DISCOVERY: One Of The Roundest Objects Ever Created By Humans

-

 By Victor Olubiye


What you're seeing in the image is not just an ordinary sphere… it’s a scientific marvel!

This sphere, made from ultra-pure silicon-28, was developed by scientists in the Avogadro Project to help redefine the kilogram using universal constants instead of physical objects.

Why is it so special?

It was crafted with such precision that its deviation from a perfect sphere is only 50 nanometers. To put that in perspective: if this sphere were the size of the Earth, its imperfections would be just 2 to 3 meters high.

This level of perfection allowed scientists to calculate exactly how many atoms it contains, which helped redefine the kilogram in 2019. Since then, the unit has been based on the Planck constant, not on a physical cylinder stored in France.

Its surface is so smooth that a single speck of dust could reveal whether it’s rotating. There’s truly nothing like it.

 The image reflects a scientific laboratory, where this technological gem was handled with extreme care and precision.

Image
By Victor Olubiye Symbolic representation of Nigeria in crisis, amid abductions, attacks, and rising insecurity. Credit: Public Domain Nigeria is reeling from a wave of crises that together expose the fragility of its security, politics, and international standing. Twenty-five schoolgirls were abducted from a boarding school in Kebbi State in a pre‑dawn raid. In Kwara State, armed bandits fired into a church during evening service, killed several people, and carried off dozens of worshippers. In Abuja, Nnamdi Kanu, leader of the proscribed Indigenous People of Biafra (IPOB), was convicted and sentenced to life imprisonment on terrorism charges. All this is unfolding against a backdrop of earlier, sharp international pressure — including a warning from U.S. President Donald J. Trump, who last month threatened military intervention in Nigeria if Christians continue to be attacked. In the early hours of Monday, November 17, gunmen on motorcycles overran the Government Girls Comprehensive ...

Polytechnics Build Creators, Universities Breed Job Seekers: The Nigerian Education Paradox

-
Image
Photo sources: Osun State Polytechnic, Iree (left); Federal University Oye-Ekiti main gate (right). By Victor Olubiye In Nigeria today, one of the most debated topics in education circles is the widening gap between university and polytechnic graduates. While universities pride themselves on academic excellence and theoretical rigor, polytechnics are quietly raising a generation of self-reliant young Nigerians who can create, build, and sustain jobs in a country where unemployment remains an unending national crisis. For students of Osun State Polytechnic, Iree, education goes beyond lectures and PowerPoint slides. In the engineering workshop, students handle real machines. In the mass communication studio, budding broadcasters produce, record, and edit programmes. Fashion students cut, sew, and design their way into entrepreneurship even before graduation. This practical-oriented system is what sets polytechnics apart. “Here, we are not waiting for anyone to employ us,” says Boluwatif...

PROFILE: Grigori Perelman – The Brilliant Mathematician Who Solved the Impossible and Turned Down a Million Dollars

-
Image
 By Victor Olubiye In a world where recognition, riches, and reputation often define success, one man defied them all—and became a legend. Grigori Perelman, a reclusive mathematician from Saint Petersburg, Russia, stunned the scientific world not only with his genius, but with an even rarer quality: indifference to fame. In the early 2000s, Perelman achieved what many believed was impossible—he solved the century-old Poincaré Conjecture, one of the most complex and elusive problems in the history of mathematics. The Poincaré Conjecture was more than just a puzzle. It was one of the seven Millennium Prize Problems, identified by the Clay Mathematics Institute in 2000 as the greatest unsolved problems in mathematics. Each came with a $1 million prize and global acclaim. The conjecture itself dealt with the very nature of space and shape in three dimensions, baffling the sharpest mathematical minds for over a hundred years. Perelman’s solution, published in a series of low-key online ...

Folake Solanke: The Woman Who Shattered Nigeria’s Legal Glass Ceiling

-
Image
 By Victor Olubiye In the grand corridors of Nigeria’s legal history, one name stands out like a shining beacon—Chief Folake Solanke, SAN, OON, CON—a woman whose brilliance and determination broke barriers, inspired generations, and redefined what was possible for women in law. Born on March 29, 1932, Solanke’s path was perhaps destined for greatness. She is the daughter of Chief Jacob Sogboyega Odulate, the celebrated pharmacist and inventor of the iconic Alabukun medicine—a household remedy whose reach spanned decades. With such a legacy of ingenuity and grit, it was no surprise that Folake carved her own path to history. After earning her law degree from the University of Newcastle, she was called to the English Bar in 1962. Returning to Nigeria, she etched her name in the nation’s legal annals by becoming the first woman to be conferred the prestigious rank of Senior Advocate of Nigeria (SAN)—a feat that made her the first woman to don the silk gown reserved for the country’s t...

Opa Oranmiyan: The Staff That Holds the Secrets of a Warrior King

-
Image
 By Victor Olubiye In the heart of Ile-Ife, the spiritual cradle of the Yoruba people, stands a tall and mysterious monolith that has defied time for centuries. Known locally as Opa Oranmiyan—the Staff of Oranmiyan—this 18-foot granite column is more than a relic. It is a living memory, a cultural compass, and a sacred link to one of the most controversial and legendary figures in Yoruba history: Prince Oranmiyan, the last son of Oduduwa. The tale of Oranmiyan is as layered as the myths of ancient Greece. Oral tradition recalls that he was born of Lakange Anihunka, a slave woman captured during war, but his paternity was shared by two titans—Oduduwa, progenitor of the Yoruba race, and Ogun, the fiery god of iron and war. This unusual origin gave him his name Oranmiyan, which loosely translates as “the child who chose controversy.” Half of his body was said to carry Ogun’s bronze-like complexion, while the other half mirrored Oduduwa’s darker hue. From birth, he was destined to be b...

Colonel Victor Banjo: The Yoruba Officer Who Crossed the Lines of War

-
Image
 By Victor Olubiye On the morning of September 22, 1967, four men were lined up at Enugu and condemned to face the guns of their comrades. Among them was a tall, soft-spoken officer whose life had once symbolized the promise of a modern Nigerian military—Colonel Victor Adebukunola Banjo. Moments later, the sound of rifles tore through the air, ending not just his life but the ambitions of one of the brightest officers of his generation. Banjo’s story is not just the tale of a soldier. It is a window into the turbulence of Nigeria’s 1960s—an era of coups, betrayals, and civil war, when loyalty to tribe or nation could decide between life and death. Born on April 1, 1930, in Ogun State, Banjo grew up in a Nigeria still under colonial rule. In 1953, he joined the Nigerian Army as Warrant Officer 52 and began a journey that would set him apart. He trained at the prestigious Royal Military Academy, Sandhurst, in the United Kingdom, where discipline and intellect combined to shape his ca...

FEATURE: Better Eat Well — Your Future Doctors Are Using ChatGPT to Pass Exams

-
Image
 By Victor Olubiye  In the lecture halls of Nigeria’s medical and health institutions, a quiet revolution is underway — not in the laboratories or operating theatres, but on smartphones, laptops, and AI chat windows. Increasingly, student doctors are turning to tools like ChatGPT to prepare for — and sometimes cheat in — their examinations. While artificial intelligence has opened new frontiers in learning, educators, students, and health professionals alike are raising a red flag: Are we training a generation of doctors who don’t truly understand medicine? At first glance, using AI-powered tools like ChatGPT for academic assistance may seem harmless — even innovative. After all, the future of healthcare is undeniably intertwined with technology. But as reports grow of students using these tools not just for study but to bypass learning altogether, the issue has become a ticking time bomb in Nigeria’s already strained medical education system. “You had better eat good food,” w...

FG Honours Late Buhari: Five Public Structures Renamed in Borno

-
Image
 By Victor Olubiye  The Federal Government has approved the renaming of five major public structures in Borno State after Nigeria’s former President, Muhammadu Buhari, in honour of his service and historical ties to the state. The decision was reached during a special Federal Executive Council (FEC) session held on Wednesday, July 17, just days after Buhari’s passing on July 13. The move is part of efforts to immortalize the late president, who served as military governor of the former North-Eastern State and played a key role in the region’s development. Among the renamed institutions is the University of Maiduguri, which will now be known as Muhammadu Buhari University. The university was established in 1975, during Buhari’s tenure as military administrator of the North-East, before Borno State was carved out in 1976. Other public assets in Maiduguri renamed after the former president include: Maiduguri International Airport, now Muhammadu Buhari International Airport Muhamm...
