I typed "solve((a/(b+c) + b/(a+c) + c/(a+b), a)" on my school-issued TINspire. The calculator took a much longer time to load than I'd ever seen it load, then gave me a huge line that I decided not to look at all of o_o

Why is "electromagnetic" energy called "electromagnetic"?
I've just started learning about currents, and that means lightbulbs! So does electromagnetic energy have a lot to do with electrons?

I remember when I first learned about energy, the teacher was grouping energies with each other, but I forgot those groups :/
