If the speed of light changes very slowly – say a small percentage every 1. November 2. 01. 7. Is there a physical limit to the wind speed of a hurricane?

If so, what is it? November 2. 01. 7. All astronomical bodies, from moons and planets up to galaxies, spin and have orbits.

In case you’ve somehow managed to avoid the growing hype, on August 21, a solar eclipse will pass over the United States. And to protect your eyesight when staring.

Why is spin unimportant for us, but at other levels it is all- pervasive? How do the laws of physics make our biosphere so special? October 2. 01. 7. People seem to come in all shapes and sizes. Do any other animals display the same amount of variation in size as humans among healthy adults?

Why is there this variety, and what are its consequences for the future? October 2. 01. 7. Watch ATM Online Fandango. It seems ubiquitous at beaches for children to build sandcastles.

During the recent total solar eclipse in the US, I overlapped my hands, using the gaps between my fingers to form "pinholes".

Just before the start of totality, someone noticed that the shadows formed through this "pinhole camera" onto a white board were so sharp that the individual hairs on my arms were visible. How thin must the solar crescent be for the shadows to be this sharp, and how soon before totality would this occur? October 2. 01. 7.

Recently, my wife's silver car became covered by a swarm of flying ants. This was odd because none of the other cars parked nearby had any on at all.
