Arthur Benjamin fait "Mathémagie" A story for tomorrow. What do we have in common with wildlife? What do. New York City by autistic artist?Stephen. Dr. Roy Lowry of Plymouth University in the UK. Dr. Roy Lowry of Plymouth University in the UK made science explosively exciting for his class by demonstrating how powerful (and loud) it can be when the pressure of cold, trapped Liquid Nitrogen, a liquified gas, is warmed in a bucket of water. Then he added 1500 Ping Pong Balls. If that didn’t make sense, watch. He’ll explain it all. And then when you see him pour the balls in and run away (it’s dangerous!) , cover your ears or turn down the volume, and let the science commence! "Wow the moon looks huge tonight!" We’ve all said. "Wow the moon looks huge tonight! " We’ve all said it, but is the moon ever larger or closer at the horizon? (No, it’s not.) Is it some visual magnification by the atmosphere? (Nope, evidently that’s not why either.) The answer(?)

: evidently our brains are playing tricks on us when we see a huge moon. The perception of the moon’s size is influenced by what’s surrounding it. Created by Mitchell Moffit and Gregory Brown, this ASAP Science video, The Moon Illusion explains why the moon looks larger near the horizon. Via Geekosystem.
