Weak and electromagnetic interactions have
actually been unified as different aspects of a
single force called the "electro-weak force."
Historically, the weak force was seen to underlie
certain kinds of radioactive decay at a sub-atomic
scale. Electromagnetic interactions, on the other
hand, affect matter at the atomic scale. However,
it has been shown that at high enough
temperatures/energies (i.e. energies exceeding the
"unification energy"), the two "types" of
interactions actually merge into one. I hope this
