Cool Science Facts

"There are a million points of light in the universe traveling a million miles an hour away from us, yet they are so far away they appear to be standing still." "Estimate for # of planets in visible universe: 10^25, which = # molecules in a cup of water" Robert Garisto, PRL "I'm is Juliet Retenford and my favorite science fact is that marmoset siblings are all genetic chimeras of each other because they all share a single placenta so a single circulation." "Hi Dr. Jim Macena, University o...

 Science is Disconnected from the Needs of Man

A plain, reasonable working man supposes, in the old way which is also the common-sense way, that if there are people who spend their lives in study, whom he feeds and keeps while they think for him—then no doubt these men are engaged in studying things men need to know; and he expects of science that it will solve for him the questions on which his welfare, and that of all men, depends. He expects science to tell him how he ought to live: how to treat his family, his neighbours and the men o...

 Energy from the Sun to Earth

It is a feature of the way the world is made that two protons together have less mass than two protons separately. This is a startling but indisputable fact. Weigh two protons separately, then weigh them together: the numbers don't match. The numbers differ by about 1 percent. This curious difference is not to be explained by some law of nature; it is a law of nature, as basic to the way the world works as any fact in our possession. The mass discrepancy is equivalent to an amount of energy g...

 Bumbling Humans Made It to the Moon

So there he is at last. Man on the moon. The poor magnificent bungler! He can't even get to the office without undergoing the agonies of the damned, but give him a little metal, a few chemicals, some wire and twenty or thirty billion dollars and, vroom! there he is, up on a rock a quarter of a million miles up in the sky.
