Now it is possible to see a movie of an electron. The movie shows how an electron rides on a light wave after just having been pulled away from an atom. This is the first time an electron has ever ...

They sound like futuristic weapons, but electron guns are actually workhorse tools for research and industry: They emit streams of electrons for electron microscopes, semiconductor patterning ...

Ernest Rutherford, pioneer in studying the world inside atoms, famously remarked that all science is either physics or stamp collecting. But sometimes physics itself involves dutifully collecting the ...
