Heavens-above.com follows satellites and constellations. There are many dozens of satellites in orbit around the Earth and this will tell you which is which, and where. There’s even a satellite for amateur radio operators. Also has information on stars and constellations.
IFLscience.com has fascinating bits, including “21 GIFs that explain mathematical concepts.” For instance, did you know that the number Pi (3.14159 etc.), is equal to the distance traveled by rolling a wheel exactly one revolution? That distance turns (ha, ha) out to be 3.14 times the diameter. This is true no matter what size the wheel.
PBS.org/Nova has all the TV episodes from the science program NOVA, the day after they air. “Vaccines, calling the Shots” takes you around the world to look at epidemics – particularly appropriate these days. “Rise of the Hackers” finds the super sleuths who decode the world’s most sophisticated cyber weapons.
“Neon flames” lets you design your own nebulae. Choose a color from the palette on the left and start moving your mouse cursor across a black sky. The color deepens if you move over and over the same section. The effect looks remarkably like a real star cluster. This is also available as an Android app.
We recently watched a NOVA science show about a guy who created a game that lets people from all over the world help find solutions to cancerous growths and viral infections. The solutions were tested in the lab, and when they didn’t work, people went back to their computers and found others that did work.
While you’re up, how about solving a problem or two? “World Community Grid” is a free program that harnesses the power of linking thousands of computers to solve problems. (We are proud to say we first suggested doing this in a column written more than thirty years ago.)
ScienceStudio.org is a collection of science videos, radio programs, animations and photos on the web. They range from well-known programs like National PublicRadio’s “RadioLab” to bloggers at NASA. We especially liked the subject “Why Is It Dark At Night.” (Remember: No matter how silly the research, somebody got a grant for it.)
“Survive! Inside the Human Body,” by Suk Young Song, is a series of three 180-page comic books, each of which is $18 from NoStarch.com. The books were originally published in Korea and have now been translated for the American market. They sold more than 20 million copies in Korea and they are terrific.
“Nova Elements,” a free iPad app, takes the periodic table off the wall into an atomic sandbox, where you can play with particles to create your own copper, gold or any one of the other 118 elements. You can then combine them to make molecules. It’s been downloaded over 570,000 times.
