Physics Uncovered on Instagram: "Prof. Walter Lewin’s well-known basketball–tennis ball experiment is a classic way to show how elastic collisions and momentum transfer work. When the two balls are dropped at the same time, the basketball rebounds off the ground and passes much of its momentum to the tennis ball. As a result, the tennis ball shoots upward to a height far greater than its original drop point. This dramatic demonstration highlights the conservation of both energy and momentum duri

Naman Pal on Instagram: "The Josephus Problem is one of the most fascinating puzzles in math & computer science. 🌀 Imagine this: 100 people stand in a circle. Starting from person 1, each person eliminates the one next to them. This continues round and round… until only one survivor is left. 😨 Now here’s the mind-blowing part → Instead of simulating the whole process, math gives us a direct formula to find the last survivor. For k = 2 (kill next person): 1. Write the number of people in binary
