How many colors are really in a rainbow?

“The colors of a rainbow so pretty in the sky. Are also on the faces of people going by.” -Louis Armstrong It’s no secret that white light is the light that we see when all the colors shine together and are seen at once. This has been known for over 400 years, when Isaac Newton…

The Sirens of Titan

“Everyone is a moon, and has a dark side which he never shows to anybody.” -Mark Twain Back before the telescope was invented, Saturn was known as the Old Man of the Skies. The slowest-moving of the naked-eye planets, it’s the only one that would reliably be in nearly the same location, year after year.…

“Through that last dark cloud is a dying star… And when it explodes, it will be reborn. You will bloom… and I will live.” -The Fountain I want to start off by letting you all know that I, myself, do not have any children of my own. I have taught children, adolescents and adults for…

Weekend Diversion: Where Bigfoot Dwells

“You never need think you can turn over any old falsehoods without a terrible squirming of the horrid little population that dwells under it.” -Oliver Wendell Holmes As an astrophysicist, I get sent all sorts of (unsolicited) novel ideas and theories claiming to overturn everything from special relativity to quantum theory to the Big Bang.…

…But What If There Was More Time?

“Well you run and you run to catch up with the Sun but it’s sinking, racing around to come up behind you again. The Sun is the same in a relative way but you’re older, shorter of breath and one day closer to death.” -Pink Floyd For the last four-and-a-half billion years, the Earth has…

The size and age of the Cosmos are beyond ordinary human understanding. Lost somewhere between immensity and eternity is our tiny planetary home. -Carl Sagan If the story of our entire Universe’s history, from the last stages of inflation and the Big Bang up to the present day, were to be compressed into one calendar…

A New Challenge, A New Job, and A New Chance

“If there is anything that a man can do well, I say let him do it. Give him a chance.” -Abraham Lincoln It was nearly four years ago that I started blogging back at my old site, branching out from the hardcore research of physical cosmology and the teaching of physics and astronomy, and into…

I am a Scientist

“Science is facts; just as houses are made of stone, so is science made of facts. But a pile of stones is not a house, and a collection of facts is not necessarily science.” -Jules Henri Poincaré The higher you fall from, the faster you’ll be moving when you hit the ground. Seems like the…

How stable is the stuff we’re made out of?

“I trust in nature for the stable laws of beauty and utility. Spring shall plant and autumn garner to the end of time.” -Robert Browning Like everything else that we know of in the Universe — galaxies, stars, and planets — human beings are made out of atoms. And just like galaxies, stars and planets,…

Open Wide! (What do you mean, my eyes?)

“I’ll do my dreaming with my eyes wide open, and I’ll do my looking back with my eyes closed.” -Tony Arata Would you believe me if I told you that — in terms of your own eyes — you saw better at night than you did during the day? It’s true! But it doesn’t have…
