Why I Set Out to Personally Teach My Kids Physics and Chemistry — A Journey from 1995 to Now

By: Dr. Salihu Lukman

Over the years, I’ve worn many hats — a student, a teacher, an engineer, a researcher, and an assistant professor of civil engineering. But today, I proudly wear one more: that of a father-educator, determined to personally guide my kids through one of the most important academic journeys of their lives — mastering physics and chemistry.

Why this sudden resolve?

Because my kids, like many SS1 (Grade 10) science students, are facing real challenges in understanding physics and chemistry. And I know — deep in my heart — that no science student can truly thrive without a solid grasp of physics, the most foundational of all the sciences.

Physics is not just another subject; I put it as the study of the basic nature of nature itself. It lays the bedrock for chemistry, which in turn supports the life sciences like biology and beyond. Without it, the scientific tower becomes shaky. Physics explains the principles behind forces, energy, motion, atoms, and the universe — giving chemistry its structure and biology its processes.

My journey with physics began in 1995 in SS1, when I was introduced to a mesmerizing physics class taught by the brilliant and renowned Mal. Ibrahim Physics, thanks to my nephew, Engr. Idris Nuhu Malami (Major). That moment planted a seed in me. Teaching SS1 physics quickly became one of my hobbies. Three decades later, that seed has flourished into a passion-driven profession.

I evolved into an applied physicist through my academic path — specializing in water engineering during my bachelor’s and master’s degrees. I’ve had the privilege of teaching university courses like engineering fluid mechanics, groundwater modeling, and engineering hydraulics & hydrology. My journey didn’t end there. I went on to earn a PhD in Environmental Engineering in 2013, becoming an applied chemist as well, with deep hands-on experience in analytical chemistry, using advanced equipment like AAS, GC-MS, ICP, Hg-Analyzer, FTIR, and HPLC in my research.

Ironically, while I’ve journeyed through so many advanced scientific fields, chemistry was actually my favorite and simplest subject back in secondary school — a love that never left me.

Given all this, I asked myself: Why hire someone to teach my children when I am more than equipped — both academically and emotionally — to do it myself? I not only understand the content deeply, but I also carry within me a long-standing passion to teach it in a way that is alive, relatable, and inspiring. Some of my former SS1 physics students are now professors.

That’s why I’m excited to announce that I’ve started teaching my kids physics and chemistry myself — and I’ve decided to share this journey and videos publicly, so that anyone struggling with these subjects can benefit as well.

Find my Introductory Physics Lesson 1 (Part 1 & 2) below, which I will be posting right here on my Facebook page and YouTube channel. This first lesson gives a general overview of physics and its profound connection to the cosmos, as well as its real-life applications that shape everything from your phone to the stars. I will also be briefly highlighting some of the established physics found in the glorious Qur’an.

And this is just the beginning

I’ll be releasing more lessons in both physics and chemistry, taught gradually, patiently, and accessibly. There will be no rush — just sincere teaching, step by step, until you or your loved ones fully grasp these essential subjects.

So if you, your child, or someone you know has ever struggled with physics or chemistry — this is for you. Let’s rediscover the beauty of science together, from the ground up.

Join me in this deeply personal and meaningful mission — not just to teach, but to inspire a generation with the knowledge that has shaped my life for 30 years. 

From passion to purpose, this is a father’s mission to teach, inspire, and empower.

The Three Faces of Truth: Navigating Objectivity, Subjectivity, and Power

By: Dr. Salihu Lukman

Your post insightfully captures the tension between emotion and reason, and how our perception is often filtered through personal and cultural lenses. This interplay between bias and rationality is exactly what gives rise to the three types of truth we encounter in life: objective, personal, and political truths — each shaped by a different level of subjectivity and influence.

🔹 Objective Truth is what remains true regardless of opinion. It survives scrutiny, testing, and time. For example, gravity causes objects to fall toward the Earth. No matter our beliefs or emotions, this truth holds because it is grounded in observable reality. But as you rightly pointed out, even our interpretation of facts can be distorted when viewed through biased lenses.

More examples of objective truth:

• Scientific: Water boils at 100°C at sea level.

• Mathematical: 2 + 2 = 4.

• Historical (verifiable): The Earth orbits the Sun.

Objective truths form the basis of science, logic, and factual reporting. They help societies build consensus around reality.

🔹 Personal Truth, on the other hand, is deeply emotional and subjective. It reflects an individual's feelings, beliefs, experiences, or perceptions. It may not be universally shared or verifiable. It is rooted in individual experience and internal conviction only. For instance, someone may say, "My faith saved my life." While this may not be scientifically measurable and verifiable, it is undeniably real to the individual who experienced it. These truths shape our identity and worldview, even if they aren't universally accepted.

More examples of personal truth:

• “I feel most alive when I’m praying.”

• “Chocolate ice cream is better than vanilla.”

• “I believe in a higher power.”

Personal truths are essential to identity, religious beliefs, mental health, and authentic self-expression. They shape how individuals relate to the world.

🔹 Political Truth often emerges from the manipulation or amplification of sentiments and group biases. It is typically constructed through repetition, influence, and power. A statement like "Our nation is always morally right in global affairs" may be more about nationalistic sentiment than fact. Political truths are often dressed in objectivity, but they serve agendas and are reinforced through echo chambers and media framing.

More examples of political truths:

• "Nigeria is one indivisible nation."

– A political ideal often repeated by leaders to promote national unity, despite persistent agitations for secession or autonomy (e.g., Biafra, Oduduwa Republic).

• "Our democracy is working."

– Frequently used to affirm legitimacy, even when elections are marred by voter suppression, rigging, or low public trust.

• "Power must rotate between North and South."

– A political belief shaping party decisions and elections, though it’s not in the Constitution. It reflects regional sentiments more than national consensus.

• "Security has improved under this administration."

– Politically useful during campaigns, despite rising incidents of banditry, terrorism, and communal clashes in several regions.

Political truths influence public opinion, policy, and social behavior. They can unify or divide, and may evolve with social movements or regime change. Remember, political truths are often ideological, emotionally charged, and sometimes selectively factual — shaped by power, public sentiment, or propaganda, rather than objective reality.

Ultimately, we must all confront the biases that color our lens and strive, as you said, to raise our objectivity threshold. Recognizing the type of truth we're dealing with — and whether it’s based on emotion, evidence, or ideology — is key to thinking clearly, judging fairly, and living wisely. 

Thanks for sparking such a profound reflection.

Dr. Hamisu’s Post

Sentiments and biases, largely influenced by emotions, can make even the most intelligent person appear foolish. Almost everyone views the world through the lens of their faith, culture, religion, tribe, needs, environment, knowledge, and experience. Most of us are guilty of confirmation bias, group think and cognitive short cuts. However, your ability to positively manage biases is your superpower. 

One must understand the interplay between the emotional and rational brain to suppress biases and be consistently rational. This task is challenging for most people.

There's something about objectivity that enhances your personality. It helps you separate biases and emotions from your observations, judgment, and decision-making, allowing you to see things clearly from different perspectives. Being rationally objective enables you to minimize personal opinions, feelings, and preconceived notions, and instead, concentrate on evidence as it appears.

An objective person is believable, reliable, respected, and, at the same time, feared, even by their enemies, whose sentimental intention is to distort facts with emotions without recourse to justice and shared humanity. 

Total objectivity is nearly impossible, but we can always strive to improve our objectivity threshold.

Engineering the Human Mind: The Case for Social Science in National Progress

 Your reflections (Dr. Usman Isyaku) on the indispensable role of social sciences in national development resonate deeply with me. As someone who has navigated the realms of engineering and public health, I've come to recognize that a foundational understanding of psychology in particular – a social science discipline - is not just beneficial but essential for fostering meaningful interpersonal relationships and comprehending the complexities of human behavior.

Psychology offers profound insights into our personalities, behaviors, and the underlying factors that influence our interactions. By delving into psychological principles, we equip ourselves with the tools to navigate relationships more effectively, understand the motivations of others, and foster environments of empathy and mutual respect.

Human behavior, though complex, can be effectively modeled using the Big Five personality model — Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism (OCEAN) — much like variables in physical or natural sciences. Each trait represents a spectrum that quantifies core aspects of personality, allowing researchers and practitioners to predict patterns of thought, emotion, and behavior across individuals and populations. For instance, a highly conscientious person tends to be organized and goal-oriented, which correlates with job performance and academic success. Similarly, high neuroticism is strongly linked to vulnerability to stress and mental health issues. By treating these traits as measurable psychological variables, we can apply statistical, computational, and experimental methods — just as we do in the physical sciences — to model, analyze, and even anticipate human behavior in different environments and social contexts. This structured approach makes personality psychology a scientifically rigorous field capable of informing interventions, improving interpersonal relationships, and enhancing mental health care.

 

Moreover, a grasp of clinical psychology can illuminate the nuances of personality disorders and mental health challenges, enabling us to approach such issues with compassion and informed support and do away with the stigma that is endemic in our sociocultural view of mental health. This understanding is crucial, especially in our diverse societal contexts, where mental health awareness is paramount and cannot be over-emphasized especially in this crucial time.

 

Reflecting on my educational journey, I often ponder how a formal education in psychology could have been my primary choice if only I could go back in time. The integration of psychological insights into our daily lives and professional practices can lead to more cohesive communities and effective problem-solving strategies.

 

In essence, embracing psychology as a vital component of our educational and personal development endeavors can bridge gaps in understanding, promote mental well-being, and enhance the fabric of our interpersonal connections.

 

In conclusion, the study of social science courses—particularly psychology, in my humble opinion—is not a luxury but a necessity in today’s increasingly complex world. As we strive for national development and social cohesion, a scientific understanding of human behavior, relationships, and mental health becomes as critical as advances in engineering or medicine. By investing in social sciences, we not only cultivate empathy and insight at the individual level but also build the societal foundations required for sustainable progress. If we are to address the root causes of our institutional and interpersonal challenges, psychology and its allied disciplines must take their rightful place at the core of our educational priorities.

 

Handy Household Tips for Better Efficiency and Food Preservation

 By: Dr. Salihu Lukman

In our daily household routines, small but effective tricks can make a huge difference. Recently, I have discovered and benefited immensely from two practical household tips that I believe will be useful for many. These simple yet powerful techniques help in food preservation and appliance longevity. Try them out and experience the benefits firsthand!

1. Extending the Shelf Life of Fruits, Vegetables, and Foods Using Cling Film

Have you ever noticed how quickly bananas, cut watermelon, cucumbers, and other fruits deteriorate in the fridge even when you enjoy a power supply 24/7? By simply using a cling film to cover these items securely, you can significantly prolong their freshness. When I saw those fruit vendors covering cut watermelons and pineapples on the street in Nigeria, I thought it was simply to protect them against flies and dust. Also, when I buy vegetables, fruits, and foods completely covered with a cling film in their containers here in Saudi Arabia, I never thought that the cling film actually prolongs the shelf life of these items when stored in a fridge and would normally remove the cling film before storing them in the fridge.

How It Works

• Cut watermelon: Typically, a cut watermelon lasts only about 4 days in the fridge before losing its freshness if you receive a constant power supply. However, when wrapped tightly with cling film, it can stay fresh for up to 14 days. The cling film minimizes exposure to oxygen and moisture loss, both of which accelerate spoilage.

• Bananas: Refrigerated bananas often turn brown and spoil within 5 days if you receive a constant power supply. But when fully wrapped in cling film and stored in a polystyrene pack or airtight container, they can last up to 14 days without losing their firmness and freshness even when they turn brown.

The Science Behind It

Cling film acts as an oxygen and moisture barrier, preventing dehydration and oxidation. Fruits and vegetables release ethylene gas, which accelerates ripening and spoilage. By sealing them properly, we reduce ethylene exposure, slow down enzymatic reactions, and extend their shelf life significantly.

2. Preventing Washing Machine’s Rigorous Shaking During Drying with Weighted Counter-Balance

If you use a semi-automatic washing machine which many people use nowadays, you might have experienced intense shaking or vibrations during the drying phase. This can cause damage over time and shorten the motor’s lifespan. A simple trick to counteract this is placing heavy materials like blankets or sweaters in the washing compartment during drying.

How It Works

• When the drying drum spins at high speeds, it creates an uneven centrifugal force if the load inside is imbalanced.

• By placing a heavy object (such as a blanket or thick sweater) in the washing compartment before starting the drying cycle, the force is evenly distributed, minimizing excessive vibrations and reducing strain on the motor.

• This simple step helps stabilize the machine and prevent unnecessary mechanical stress, prolonging the motor’s life and reducing noise.

Try These Hacks and Experience the Difference!

Both of these techniques are simple yet highly effective, saving you money and improving efficiency in your home. Give them a try, and let me know how they work for you. Do you have any other handy household tips? Share them in the comments for us to gain from your experience!

The Link Between Intelligence and Mastery of the English Language

 By: Dr. Salihu Lukman

The ability to communicate effectively in one’s native language is often seen as a measure of intelligence, particularly in societies where that language is the primary medium of education and discourse. In English-speaking countries where individuals receive their education solely in English, mastery of the language—both in written and spoken forms—can be an indicator of intelligence. While intelligence is multifaceted and cannot be solely determined by linguistic proficiency, the ability to articulate thoughts with precision, use rich vocabulary, and convey complex ideas effectively in English can reflect cognitive ability, critical thinking, and intellectual depth.

Mastery of English as a Reflection of Intelligence

English proficiency is crucial in academic and professional settings, where clear communication could determine success. A person who articulates ideas succinctly – especially in the social sciences, arts, and law - understands nuances in language, and conveys meaning with depth demonstrates strong cognitive ability. This does not mean that articulation of ideas is not needed in the science and applied science disciplines like engineering and medical sciences. 

Similarly, in the professional world, a person who speaks and writes well often commands respect and exudes confidence. A lawyer who presents compelling arguments in court, a scientist who explains complex theories in a simple manner, and a business executive who writes persuasive proposals all demonstrate intelligence through their command of the English language.

Shall we look down upon or destructively criticize someone with poor English grammar?

In my humble opinion – no - not because I belong to that group. We should not look down upon someone with poor English grammar. Language proficiency depends on various factors, including education, exposure, and native linguistic background. Some people may excel in other fields—such as science, mathematics, or engineering—but struggle with grammar. Instead of judgment, offering guidance and encouragement fosters growth.

What truly matters is a person’s ability to communicate their ideas effectively. If grammar errors hinder clarity, constructive feedback can help. Intelligence is multifaceted, and no single skill—be it language, math, or science—defines a person’s worth or capability.

Do women learn a new language more easily than men?

Yes, research suggests that women tend to learn new languages more easily than men, and neuroscience provides several explanations for this difference. Hence, it is not surprising to see women mastering the English language better than men. While men can certainly excel in language learning, neuroscience suggests that women have biological and cognitive advantages that may make language acquisition easier and faster for them. However, motivation, exposure, and learning strategies remain critical factors for both genders.

Notwithstanding the foregoing, I still doff my hat to those who speak or write proficiently in the English language. Some notable mentions are:

1. Prof. Farooq Kperogi: To read his articles comprehensively, your dictionary must be by your side because you will come across several words that you have never seen before. Not even a native English writer can come close to his mastery of the English language. He memorized a complete dictionary during his secondary school days to enable him to write a letter or speak in impeccable English to impress girls, and now, he is impressing the whole world with his language skills.

2. Dr. Salisu Lawal Usman: The barrister, as I fondly call him. Every post or comment of his sends me to look for my dictionary and start looking up those new entries that I have never seen before. He also memorized a dictionary like Kperogi.

These two guys are all first-class brains, even though they might not have earned a first-class degree during their undergraduate days, but trust me when I tell you that they are first-class in whatever they do. I did not include Hon. Patrick Obahiagbon, a former parliamentarian because I think he hardly communicates in his speech. While I can fetch the words written by the above 2 persons, many of Obahiagbon’s words sound completely Greek to me. I don’t know if he has a separate dictionary that is different from ours. I listen to him whenever I want to laugh.

Other notable mentions whose command of the English language fascinates me include orators, public speakers, etc.: Vice President Kashim Shettima, H.E. Muhammadu Sanusi II (SLS), former NSA to former President Buhari – General Babagana Monguno (rtd.), late Sir Abubakar Tafawa Balewa (1st Nigerian Prime Minister), late Maitama Sule Danmasanin Kano, Mallam Nasir El-Rufa’i, Prof. Yemi Osinbajo (former Vice President), Alhanislam's poetry, Prof. Yusuf Usman (former NHIS boss), and Dr. Fatima Mahmud (my beloved wife). 

The Importance of Mastering English Idioms

Idioms are an integral part of any language, adding depth and vividness to speech and writing. Mastering English idioms allows individuals to express themselves creatively and engage listeners more effectively. For instance, instead of saying, "He works very hard," one could say, "He burns the midnight oil," making the statement more expressive.

Other examples include:

• "Bite the bullet" – To endure something difficult without complaint.

• "The ball is in your court" – It’s your turn to take action.

• "A blessing in disguise" – Something that seems bad at first but turns out to be beneficial.

A person who skillfully incorporates idioms into conversations or writing demonstrates a nuanced understanding of the language, which is often associated with intelligence and cultural awareness. Native English speakers use different idioms every day. You will agree with me if you watch American movies. There are various channels on TikTok and Instagram teaching the meanings of various idioms especially those frequently used by the natives in everyday conversation.

The Importance of Correct Pronunciation and Syllable Stress

Pronunciation plays a critical role in effective communication. Mispronouncing words can lead to misunderstandings and, in professional settings, can undermine credibility. Thankfully, online pronunciation dictionaries like Cambridge Dictionary provide audio pronunciations in both UK and US formats that can help learners perfect their speech.

Understanding syllable stress is also vital, as incorrect stress can alter the meaning of words. For example:

• "Record" (noun) vs. "record" (verb) – She broke the world record vs. He will record the meeting.

• "Present" (noun) vs. "present" (verb) – She received a present vs. He will present his findings.

Even native English speakers benefit from refining their pronunciation to ensure clarity and professionalism in communication. 

Because our language of instruction is English from nursery to the university levels, people usually don’t feel the need to refine and correct their pronunciation. They assume that whatever their teachers spoke, was correctly pronounced and may not double-check any word for its correct pronunciation. Unfortunately, this is not true! Our pronunciation leaves a lot to be desired. Yet, when anyone tries to pronounce words as correctly as he can, he becomes a subject of ridicule. Bature, wai shi zai nuna mana ya iya turanci! Munga Mungo Park a wajen turanci.

I had a conversation with my son Muhammad one day when I corrected his pronunciation of the word SACHET. He responded with a logical question, if everyone around him mispronounces it, what benefit will his correct pronunciation amount to? I responded thus, do you want to study in Saudi Arabia after finishing secondary school? He replied, yes. Then I told him that he needed to take an international English language proficiency exam called TOEFL (Test of English as a Foreign Language) before he could apply to study in Saudi Arabia. I informed him that I took the exam before I won a scholarship to study for my PhD in Saudi Arabia and the exam had an oral section in which you will be given a topic to talk about. I warned him that if he spoke carelessly, pronouncing English words incorrectly, the native English speaker who was going to mark him might find it difficult to understand his speech and could mark him down as a result of not comprehending his points. I did not know if he was convinced by my argument. 

Some notable mentions of persons whose English pronunciations and intonations fascinate me include: the late Sir Abubakar Tafawa Balewa (also called the golden voice of Africa), the late Maitama Sule Danmasanin Kano, and Sheikh Muhammad bin Uthman (English, Arabic & Hausa), Prof. G.Y. Sadiq (English Department, ABU Zaria), late Ciroman Zazzau - Engr. Abdullahi Nuhu (Baban Ingila), Prof. Yusuf Usman (former NHIS boss), and Alhanislam's poetry.

A popular Hausa TikToker, Babban Kai, is seriously trying to educate on the correct pronunciation of English words by quoting other celebrities and renowned personalities who might have pronounced some words incorrectly as per his judgment. Even though he receives a lot of backlash from other TikTokers due to his approach and the correctness of some pronunciations, I still gain a lot from his clips, especially useful English equivalents of some peculiar Hausa adages. Many Hausa adages have English equivalents, demonstrating the universal nature of wisdom and expression across cultures. Understanding these idiomatic parallels enriches cross-cultural communication. By mastering both English idioms and their equivalents in other languages, individuals can communicate with greater cultural depth and intellectual richness. I also find Collinspiration’s page on Instagram and YouTube very educating in this regard.

Conclusion

While intelligence is not solely defined by language proficiency, a person’s ability to master the English language—through vocabulary, idioms, pronunciation, and cultural expressions—often reflects their cognitive abilities and intellectual capacity. In a world where communication is key, excelling in language skills could provide individuals with an edge in education, career advancement, and interpersonal interactions, especially in Nigeria where the official language is English. Regardless of one’s natural talents in other fields, continuous learning, and refinement of language skills remain an essential aspect of personal and professional development.

A Triumph of Grace and Grit: Celebrating My Wife’s Perfect 5.0 GPA in Her Most Challenging Semester

 By: Dr. Salihu Lukman

There are moments in life when words fall short of capturing the depth of admiration, joy, and pride one feels for a loved one. Yesterday, I found myself in such a moment—struggling to articulate the sheer brilliance, determination, and resilience my beloved wife, Anisa Abdullahi Abba, has demonstrated in her academic journey. Her recent achievement—a perfect 5.0/5.0 GPA in what has been her most turbulent and challenging semester yet—is a testament to her unwavering commitment to excellence, a shining symbol of her indomitable spirit, and a triumph that fills my heart beyond what words can convey.

To say that the penultimate semester was tough would be an understatement. It was, without a doubt, the most grueling test of her perseverance, patience, and strength. Balancing the rigorous demands of her biotechnology undergraduate degree program while navigating the complexities of life, she faced hurdles that would have overwhelmed even the most resolute individuals. Yet, in the face of these daunting challenges, she emerged not just victorious but spectacularly so—with parallel As across all her courses, a feat that propelled her already stellar cumulative GPA from 4.80 to an even more formidable 4.83, further solidifying her place in the esteemed league of first-class scholars.

A 5.0 GPA is not just a number; it is a reflection of countless sleepless nights, endless hours of study, unyielding dedication, and a mind fueled by an unrelenting thirst for knowledge. It speaks volumes of the intelligence, discipline, and sheer willpower that define my wife. Achieving perfection in such an academically rigorous field is nothing short of extraordinary, and I am left in awe of her brilliance.

Beyond academics, what makes this achievement even more inspiring is the woman behind it—who, despite the weight of her engagements, never wavered in her pursuit of excellence. She is the embodiment of grace under pressure, and her success is a beacon of hope for all women daring to chase their dreams, no matter how insurmountable the obstacles may seem.

As her husband, my heart swells with boundless pride. I have always believed in her, and time and again, she has proven that my faith in her is well-placed. But this moment—this resounding triumph—is one that I will cherish forever. It is a reminder that greatness is not handed to us but earned through resilience, sacrifice, and an unshakable belief in oneself.

So today, I celebrate my wife—not just for the perfect GPA, but for the extraordinary woman she is. For her brilliance, her tenacity, her passion, and her ability to shine even in the darkest of times.

You have conquered yet another peak, and I have no doubt that the summit of success is yours to claim. Congratulations, my love—this is your moment, and I am honored to stand by your side, cheering you on, now and always.

The Hidden Gifts of Mental Diversity: When Challenges Spark Extraordinary Achievements

 By: Dr. Salihu Lukman

Preamble

Mental disorders are often painted in a negative light, but what if some of these conditions actually harbor hidden strengths? While every mental condition comes with its own set of challenges, certain traits associated with these disorders can fuel creativity, focus, and leadership—allowing some individuals to achieve feats that might otherwise seem out of reach. Here’s an exploration of several disorders where, on the flip side, extraordinary potential lies waiting to be harnessed.

Bipolar Disorder: The Dual-Edged Sword of Intensity

Bipolar disorder is characterized by episodes of depression interwoven with periods of elevated mood. In Type 1, these episodes include full-blown mania, while Type 2 is marked by hypomania—a less disruptive but still potent burst of energy to pursue goal-directed activities and come up with useful innovations that could have far-reaching positive impacts.

Prominent Symptoms:

• Mania: Increased energy, excessive talking, impulsive decision-making, reduced need for sleep, and sometimes psychosis.

• Hypomania: Similar symptoms without severe disruption in normal function and no psychosis, often going undetected by those around the individual.

During hypomanic or manic episodes, individuals often experience a surge in creativity and intellectual prowess. This heightened state can lead to breakthroughs—whether composing a hit song or inventing revolutionary ideas—that might never emerge during their more subdued phases. Historical giants like Isaac Newton (who reportedly penned Principia during an 18-month high-energy phase and was subsequently depressed) and Albert Einstein have been speculated to have been bipolar, their fluctuating energies pushing them toward groundbreaking discoveries. Newton is undoubtedly the greatest scientific mind the world has ever seen with Einstein coming a distant second. Even modern musical icons such as Kanye West have harnessed these bursts of inspiration to redefine music.

ADHD: The Power of Hyperfocus

Attention Deficit Hyperactivity Disorder (ADHD) is often associated with inattention, procrastination, poor executive functions, and a lack of motivation for routine tasks. Yet, individuals with ADHD frequently possess an extraordinary ability: hyperfocus.

Prominent Symptoms:

• Difficulty sustaining attention on mundane tasks

• Procrastination and occasional impulsivity

• A unique capacity to dive deeply into topics that truly captivate them

When something genuinely interests them, people with ADHD can lock in their attention and absorb new skills at lightning speed. This intense focus allows them to master subjects rapidly—a talent that, when nurtured from a young age, can lead to exceptional expertise and innovation. For parents and educators, recognizing and cultivating these interests is key to unlocking a world of potential.

Autism Spectrum Disorder (ASD): Masters of Detail and Focus

Those on the Autism Spectrum often exhibit remarkable attention to detail and the ability to hyperfocus, traits that are invaluable in fields requiring precision and innovation. Many individuals with ASD also show symptoms of ADHD, further enhancing their capacity for deep concentration.

Prominent Symptoms:

• Intense focus on specific interests

• Exceptional attention to detail

• A tendency to engage in repetitive but skill-enhancing behaviors

• Lack of social skills

Consider Elon Musk, who has spoken openly about his experiences with Asperger’s Syndrome—a condition on the autism spectrum. Musk’s unique way of thinking has been a driving force behind his ventures: from electric vehicles with Tesla, to reusable rockets with SpaceX, underground transportation via The Boring Company, cutting-edge brain-computer interfaces through Neuralink, and the latest artificial intelligence research at xAI. His success illustrates how the distinctive traits of ASD can lead to revolutionary innovations.

Personality Disorders: When Extreme Traits Forge Uncommon Leaders

Not all conditions traditionally seen as disorders are purely negative. Certain personality disorders, when channeled appropriately, can foster extraordinary drive and leadership.

Obsessive-Compulsive Personality Disorder (OCPD)

Individuals with OCPD are known for their perfectionism and strict adherence to rules, ethics, and structure. Their intense focus on organization and financial prudence can transform them into principled leaders and high-achieving entrepreneurs.

Prominent Traits:

• Workaholic tendencies and perfectionism

• Rigidity in following moral, ethical, and religious codes

• Inflexibility combined with financial prudence

While Obsessive-Compulsive Disorder (OCD) is distinct and can be debilitating, its obsessive attention to detail also shares a common thread—sometimes pushing individuals toward remarkable precision and quality in their work.

Narcissistic Personality Disorder (NPD)

Narcissism carries a bad reputation, but classical narcissists are often charismatic, clever, charming, and confident—the so-called 4Cs. When harnessed positively, these qualities can lead to tremendous productivity and success.

Prominent Traits:

• Charisma, cleverness, charm, and confidence, arising from an inflated sense of self-image to gain admiration and validation.

• A tendency toward transactional empathy (or a lack thereof), meaning they often expect something in return

• A relentless pursuit of the 3Ps: power, pleasure, and profit

Many brilliant entrepreneurs and business leaders exhibit these traits, using their drive and self-assurance to amass wealth and achieve high goals. These properties make them on average brilliant, goal-getters, and richer than the average population.  However, it’s worth noting that a communal narcissist may use these traits for community benefit, even if their empathy doesn’t extend to their immediate circle—illustrated by the Hausa adage, “Inuwar giginya, na nesa ka sha” (the shadow of your greatness benefits those far away, but not those close to you).

Psychopathy (Antisocial Personality Disorder)

While psychopathy is often associated with criminal behavior, a surprising number of high-level executives and leaders exhibit psychopathic traits. About 1 in 5 CEOs have been identified as having psychopathic tendencies. These individuals are resilient, exploitative, and sometimes manipulative—using their charm and ruthlessness to ascend corporate ladders.

Prominent Traits:

• High resilience and a fearless attitude with zero anxiety

• Tendency toward manipulation and extreme exploitation

• Exceptional ability to remain calm and make decisions under pressure

Though these qualities can, in some contexts, drive remarkable corporate success, they come with ethical caveats. The resilience and decisiveness can be beneficial in leadership roles, but the potential for harmful behavior means it’s best not to aspire to these traits. After all, psychopaths are born and not made like the narcissists!

Embracing the Duality

From psychiatric illness (bipolar), neurodevelopmental disorders (ADHD & ASD), to personality disorders (NPD, OCPD, ASPD), it’s clear that mental disorders and personality variations are complex and multifaceted. While they undoubtedly pose significant challenges, under certain circumstances they can also cultivate the unique strengths needed to drive innovation, leadership, and groundbreaking achievements. Recognizing and harnessing these “beneficial” aspects doesn't diminish the struggles that come with these conditions, but it does invite us to view mental diversity through a more balanced lens.

In a world that often prizes conformity, perhaps it’s the very traits we deem unconventional that hold the key to extraordinary accomplishments. By understanding and where necessary, supporting individuals with these conditions—rather than simply stigmatizing them—we open the door to a future rich with innovation and diverse leadership. Embrace the complexity. In every challenge, there may be a hidden gift waiting to be discovered.

Is Rainwater Holier and Healthier Than Other Sources of Water?

By: Dr. Salihu Lukman

Introduction

Rainwater has long been regarded as a pure and natural source of water, often associated with blessings and renewal. In some regions, particularly in Nigeria, certain individuals believe that rainwater is holier and healthier than other sources, even to the extent of drinking only rainwater throughout the year. Traditional healers have also recommended rainwater for medicinal purposes. This article seeks to explore the religious, scientific, and environmental perspectives surrounding the purity and safety of rainwater. We will analyze Qur'anic verses and hadiths, examine the water cycle and origins of Earth's water, discuss the potential contamination of rainwater, and compare its mineral composition to other sources, particularly Zamzam water. By addressing these points, we aim to provide a balanced understanding of whether rainwater holds any superior status over other water sources.

1. Is There Any Hadith or Qur’anic Verse Indicating That Rainwater is Holier Than Other Sources?

Rainwater is described in the Qur’an as pure and beneficial, but no verse or hadith explicitly states that it is holier than other sources of water. The following verses highlight its purity:

• “And We sent down from the sky pure water” (Qur’an 25:48). This verse emphasizes that rainwater is clean and suitable for consumption.

• “And We send down from the sky water in due measure, and We cause it to soak into the soil, and We certainly are able to drain it off (with ease).” (Qur’an 23:18).

Prophet Muhammad (PBUH) also acknowledged the purity of rainwater:

• Anas ibn Malik (RA) narrated: “We were with the Messenger of Allah (PBUH) when rain fell upon us. The Messenger of Allah (PBUH) then removed part of his garment so that the rain could touch his skin. We asked: ‘O Messenger of Allah! Why did you do that?’ He replied: ‘Because it has just come from its Lord.’” (Sahih Muslim 898).

This hadith indicates that the Prophet (PBUH) regarded rainwater as a fresh blessing from Allah, but it does not declare it holier than other water sources. In contrast, Zamzam water has been explicitly declared the best water on earth:

• “The best water on the face of the earth is the water of Zamzam. It is a kind of food and a healing from sickness.” (Sahih al-Jami’ 3302).

Thus, while rainwater is pure and beneficial, Islamic teachings do not assign it a superior status over other water sources.

2. The Formation of Rainwater: The Hydrologic Cycle and Theories of Water’s Origin

The total amount of water in the Earth's water cycle remains relatively constant, estimated at 1.386 billion cubic kilometers (km³). This water is distributed among various reservoirs:

• Oceans: ~97.5% of Earth's water

• Freshwater: ~2.5%, mostly in glaciers (~68.7%) and groundwater (~30.1%)

• Surface water & atmosphere: Lakes, rivers, and atmospheric water make up a tiny fraction (~1.2% of freshwater)

Despite continuous movement through evaporation, condensation, precipitation, and collection, the total water volume does not increase or decrease significantly. However, its distribution changes over time due to climate effects, human activities, and natural processes.

Rainwater is formed through the hydrologic (water) cycle, which consists of the following stages:

1. Evaporation – Water from oceans, lakes, rivers, and other water bodies turns into vapor due to solar heat.

2. Condensation – The vapor rises, cools, and forms clouds.

3. Precipitation – Water droplets combine and fall as rain, snow, or hail.

4. Collection – Rainwater returns to the surface, replenishing groundwater, lakes, and oceans.

Theories of Water’s Origin on Earth:

1. Volcanic Outgassing Theory: Suggests that water vapor released by volcanic activity condensed to form oceans.

2. Cometary Theory: Proposes that icy comets brought water to Earth.

3. Asteroid Hydration Theory: Suggests that hydrated minerals in asteroids release water over time.

Scientific studies on ocean water composition indicate that Earth’s water has contributions from multiple sources, supporting these theories.

Qur’an 79:31 states:

"And He brought forth from it its water and its pasture."

This verse aligns with the Volcanic Outgassing Theory, which suggests that Earth's water originated from water vapor released through volcanic activity. According to this theory, in the early stages of Earth's formation, intense volcanic eruptions released gases, including water vapor, which later condensed to form the first bodies of water. The Qur'anic phrase "He brought forth from it its water" could be interpreted as referring to this process—water being released from within the Earth rather than arriving from an external source like comets.

This verse, therefore, supports the scientific view that at least some of Earth's water originated from deep within its crust through volcanic processes, reinforcing the idea that multiple sources contributed to the planet’s water supply.

3. Potential Contamination of Rainwater: Acid Rain and Its Effects

As rainwater falls, it can become contaminated by atmospheric pollutants such as sulfur dioxide (SO₂) and nitrogen oxides (NOₓ), leading to acid rain. Acid rain damages buildings, corroding structures made of limestone and metal.

pH and Mineral Content of Rainwater in Different Areas:

• Rainwater pH varies from 5.6 (natural) to as low as 4.0 in polluted areas.

• Nigerian rainwater studies (e.g., Lagos and Kano, 2020) found pH levels between 5.2 and 6.5, with low mineral content.

• Compared to Zamzam water, which has essential minerals like calcium and magnesium, rainwater lacks significant minerals that benefit human health.

Health Implications of Drinking Rainwater:

• Low pH can erode tooth enamel and affect digestion.

• The absence of essential minerals like calcium and magnesium may lead to deficiencies.

• Unlike Zamzam water, which contains beneficial electrolytes, rainwater is demineralized and not the best choice for long-term hydration.

4. Risks and Precautions in Rainwater Harvesting

Rainwater harvesting can lead to contamination if not properly managed. Risks include:

• Roof Contamination: Bird droppings and dust introduce bacteria.

• Storage Issues: Stagnant water can promote algae and mosquito breeding if left open.

• Leaching of Chemicals: Plastic and metal storage tanks can leach harmful substances, especially under direct sunlight.

Precautions to Ensure Safe Rainwater Storage:

• Use clean, non-toxic storage materials (e.g., food-grade plastic or stainless steel).

• Filter and boil rainwater before consumption.

• Regularly clean storage tanks and harvesting surfaces.

• Test water quality periodically to ensure safety.

Conclusion

While rainwater is pure and a blessing, Islamic teachings do not declare it holier than other water sources. Scientific analysis also shows that rainwater, though clean, lacks essential minerals compared to sources like Zamzam water. Moreover, environmental pollution can compromise its safety. Proper harvesting and storage are essential for maintaining its quality, but for long-term health benefits, mineral-rich drinking water is preferable.

The Holy Zamzam Water: Treatment & Health Benefits

 By: Dr. Salihu Lukman

Preamble

As a public health (environmental) and water engineer, I am frequently asked questions about the quality, treatment, and scientific significance of Zamzam water. Many people inquire whether it undergoes modern purification processes if it can be pumped, and whether scientific studies have confirmed its health benefits. Additionally, some misconceptions exist regarding the logistics of its distribution and whether it can be transported via pumping systems.

In this article, I will address these queries, dispel myths about the water’s pumping feasibility, and explore its remarkable health properties, supported by both modern scientific research and the sayings of Prophet Muhammad (PBUH). The Prophet (PBUH) said: 

“The water of Zamzam is for whatever purpose it is drunk for” (Ibn Majah 3062, Ahmad 15149). 

This hadith emphasizes the sacred and beneficial nature of Zamzam water for those who consume it with sincere intentions.

1. Treatment of Zamzam Water: Historical and Modern Practices

During the time of Prophet Muhammad (PBUH), Zamzam water was consumed directly from the well without undergoing any form of treatment. It was regarded as pure and was known for its spiritual and medicinal benefits.

In modern times, to ensure the safety of millions of pilgrims, several measures have been implemented:

• Regular Testing: The Saudi Geological Survey (SGS) conducts daily tests on Zamzam water. Samples are analyzed at the King Abdullah Zamzam Water Distribution Center in Mecca, where advanced laboratories monitor water quality.

• Filtration Systems: Modern filtration techniques remove particulate matter to maintain clarity and purity, ensuring that Zamzam water is free from sediments and external pollutants. 

• Ultraviolet Treatment: Zamzam water undergoes ultraviolet (UV) treatment to eliminate microbial contaminants while preserving its unique properties.

2. Scientific Health Benefits of Zamzam Water

Beyond its spiritual significance, medical research has validated several health benefits of Zamzam water. One of the most notable findings is its antihyperglycemic properties, particularly in diabetic conditions.

• Antihyperglycemic Properties: A study published in Asian Gulf Journal of Scientific Research (April 2022) examined the effects of Zamzam water on diabetic rats. The results indicated a significant reduction in fasting blood glucose levels and low-density lipoprotein (LDL) cholesterol after ten weeks of consumption.

• Antioxidant Benefits: Research published in the Journal of Taibah University Medical Sciences (January 2021) highlighted Zamzam water's rich antioxidant properties. The study found that it reduces oxidative stress, a key factor in insulin resistance and diabetes, making it beneficial for metabolic health.

• Higher Mineral Content: Zamzam water is naturally alkaline, containing higher concentrations of calcium, magnesium, and fluoride compared to regular water. These minerals contribute to improved hydration, bone health, and dental protection.

• Gastrointestinal Benefits: Some studies suggest that drinking Zamzam water aids digestion and supports gut health due to its unique composition and balanced mineral content.

Prophet Muhammad (PBUH) also emphasized its healing properties, stating: 

“The best water on the face of the earth is the water of Zamzam. It is a kind of food and a healing from sickness” (Sahih al-Jami’ 3302).

3. Can Zamzam Water Be Pumped?

A common myth suggests that Zamzam water cannot be pumped, leading to misunderstandings about its modern distribution. However, this is incorrect.

• Pumping Mechanisms: Zamzam water is efficiently extracted using advanced pumping systems installed by the Saudi government. These systems transport the water from the well to storage and distribution facilities, ensuring accessibility for millions of pilgrims each year.

• Distribution Network: Zamzam water is transported from the well to the King Abdullah Zamzam Water Distribution Center, located about 4.5 kilometers from Masjid al-Haram. From there, around 120 tons are shipped daily to Al-Masjid al-Nabawi in Madinah.

These modern engineering solutions ensure that Zamzam water reaches the faithful across various locations while preserving its purity and sacred significance.

Conclusion

Zamzam water remains an unparalleled spiritual and medicinal blessing in Islam. While historical accounts attest to its purity, modern filtration and ultraviolet treatment processes ensure its safety for widespread consumption. Scientific research confirms its remarkable health benefits, particularly its antihyperglycemic and antioxidant properties. Furthermore, contrary to myths, Zamzam water is successfully pumped and transported across Saudi Arabia and beyond.

As believers, we cherish the words of the Prophet Muhammad (PBUH), who declared Zamzam water to be a source of healing and fulfillment. Whether consumed for its spiritual blessings or health advantages, its significance remains timeless.
