  But it makes your voice go all squeaky! So it’s easier to call people a chicken CHEEP CHEEP CHEEP CHEEP

  Inside a lightbulb it get excited. Inside a laser it gets so excited that when there’s a population inversion energy entering and exiting the atom can be accumulated between two mirrors and when the amount of power is just right, it can be released in the form of a powerful beam of intense light.

  Physics professor: That’s not true! You can make nuclear fusion with helium-3 which doesn’t make the reactor core radioactive over time. And I think that’s cool!

    That is a bit of cheating, speaking as a phycisist. We say “if we add enough energy to system X thing Y will happen” about almost everything. :-)

      True and, speaking of nuclear fusion, it’s a big if. Given the amount of “enough energy” needed.

  The most boring element is boron.
