Nuclear science is the study of sub-atomic particles and their application in various disciplines. Here you can learn about nuclear power plants, atomic theory and radiation.


How Radioactive Cleanup Works

It's lunchtime, and you've spastically spilled soda all over your desk. Chances are you could tackle that mess faster than we could say "Mr. Clean." What do you do though when the spill is radioactive?

    What exactly is the Higgs boson?

    Who wants to reduce our complicated universe down to its simplest building blocks? A bunch of particle physicists, that's who. Why is the Higgs boson critical to that goal? See more »

  • What would nuclear winter be like?
    What would nuclear winter be like?

    If the sight of a mushroom cloud burning above the horizon suggests that the nuclear weapon-equipped world might end with a bang, then nuclear winter presents the notion that post-World War III humanity might very well die with a whimper. See more »

  • How a Nuclear Meltdown Works
    How a Nuclear Meltdown Works

    It's hard to get beyond Fukushima Daiichi when you think about nuclear meltdowns, but in fact the first one occurred decades ago, in 1969, in Switzerland's Lake Geneva region. How does such a cataclysmic incident occur? See more »

  • How does a Crookes' radiometer work?
    How does a Crookes' radiometer work?

    I once saw this device shaped like a light bulb. It had a vertical support inside it, and on that support there were four vanes with four diamonds on the end. One side of the diamond was black and the other was white. I did a little research and found out that it was called a Crookes' radiometer -- how does it work? See more »
