After 1 year in orbit, according to relativity, Scott Kelly became 0.01 seconds younger than everyone on Earth, including his twin brother

In 1951, Robert M. Fano, a professor at MIT, assigned his information theory students a deceptively simple-sounding problem as a final term paper: find the most efficient way to represent numbers, letters, or symbols using binary code. What he didn't reveal was that this was an open problem - one that even Fano himself and Claude Shannon had been wrestling with for years. One of Fano’s students, David A. Huffman, rose to the challenge. He not only solved the problem but discovered a theoretically optimal solution under certain constraints. This solution - now known as Huffman coding - is the basis for many modern file compression algorithms, including those used in ZIP, JPEG, and MP3 formats.

Here's an easy way to measure the acceleration of gravity at home with a yardstick, a bouncy ball and a stopwatch. h? - height of the drop h? - height of the 1st bounce T? - time for x bounces c=√(h?/h?)

This is one of the biggest numbers you can find in a physics paper. It's the expected distance one would travel before encountering another visible-universe-sized region of space with an identical quantum state as ours.

About 85% of people only breathe out of one nostril at a time. This is due to a tissue that swells in one nostril and shrinks in the other creating only one open airway. This 'nasal cycle' changes every 2.5h
