Image
On July 16, 2025, a 54-pound (24.5 kg) Martian meteorite named NWA 16788  shattered records by selling for $5.3 million at a Sotheby’s auction in New York . This extraterrestrial rock, the largest piece of Mars ever found on Earth, has sparked fascination not just for its rarity but also for its scientific and cultural significance.   But why is a chunk of Mars worth millions? And what will its new owner—who remains anonymous—do with it? Let’s explore the story behind this cosmic treasure.   Why Is This Mars Rock So Expensive? 1.

Image
  In a time when opinions flow freely and narratives are shaped with just a few keystrokes, the ability to back up a claim with verifiable data and charts has become not just a privilege — but a necessity. A recent conversation with a senior professional brought this to light. We were discussing Nigeria’s former presidents and their economic impacts, particularly the contrasting legacies of Goodluck Jonathan and Muhammadu Buhari . I argued — like many Nigerians do — that the economy under President Jonathan was stronger and more stable than it became during Buhari’s tenure. But when I was asked: “What data or analysis supports your conclusion?” my response was vague: “I saw it online and heard it in the news.” That moment stirred something deeper in me — a hunger not just to form opinions, but to understand them through facts . 📌 Why Data and Charts Matter in the Age of Information 1. They Cut Through Noise and Bias Opinions are everywhere — on social media, in conversati...

Image
The recent Israeli strike that killed children waiting at a health center in Gaza is a heartbreaking reminder of the devastating human cost of war. This incident, like so many others in the ongoing conflict, raises urgent legal and ethical questions: Who is responsible? What does international law say? And when does self-defense cross into unlawful violence?   1. The Rules of War: Protecting Civilians   International Humanitarian Law (IHL)—also called the "laws of war"—sets clear rules to minimize suffering in conflicts. Key principles include:   - Distinction : Combatants must always  distinguish between military targets and civilians. Schools, hospitals, and homes should never be attacked .   - Proportionality : Even if a military target exists, the attack must not cause excessive  civilian harm compared to the expected military advantage .   - Precautions : All possible steps must be taken to avoid civilian casualties , incl...
