“A large school of mobula rays fades into the waters of Baja, Mexico. “The rays were moving quite fast and it was hard enough keeping up with them from the surface, let alone diving down to take a closer look,” writes photographer Eduardo Lopez Negrete. Mobula rays are often referred to as flying rays due to their fondness for breaching.” — the 2014 National Geographic Traveller Photo Contest
Let’s also keep in mind that a mobula ray can reach 17 foot (5.2 meter) wingspan and weigh over a ton. Freaky or cool?
I love how the houses in ARITHMETICS are arranged according to the Fibonacci sequence.
When you fire particles over different trajectories at the same initial speed and record their highest points, the curve joining these points appears to be an ellipse. This article on arXiv presents the calculations behind this ballistic curiosity.

I don’t think I’ve met anyone who isn’t properly defined by their past in one way or another. There are some incredible things to be learned from past mistakes, so I don’t understand why anyone would want to forgo that opportunity for the sake of having a “clean slate” in life. A person who isn’t ‘defined by their past’ would be awfully dull in my book.
