Electrons Cause Fission Less Effectively than Do PhotonsIn efforts to understand fission better, at least two groups are measuring cross sections for electron‐induced fission. Their values are c...
There are other losses as well. Electrons have to flow from one side of the cell to the other through an external circuit. We can cover the bottom with a metal, allowing for good conduction, but if we completely cover the top, then photons can't get through the opaque conductor and we...

When electrons are excited by photons, they produce a flow of electricity known as a direct current. Below, we'll dive into each of these steps in more detail: 1. PV cells absorb incoming sunlight The photovoltaic effect starts with sunlight striking a photovoltaic cell. Solar cells are made...

When electricity flows into the electrodes, electrons (shown here as red dots) boil" from their surface and shoot off down the thin white tubes, which contain mercury gas, shown here as bigger blue dots. As the electrons hurtle down the tubes, they collide with atoms of the mercury. The ...
Artwork: Isotopes are atoms of an element that contain the same number of protons and electrons but different numbers of neutrons. An unstable (radioactive) isotope will naturally try to make itself more stable by getting rid of some of these particles and changing into a different atom....
as exemplified by stars, it is inefficient. For this reason alone, incandescent bulbs – which waste a tremendous amount of heat energy – are tragically inefficient when compared to CFLs, which excite and elevate electrons by simply passing electricity through tubes that contain vapors of argon...
Electrons have to flow from one side of the cell to the other through an external circuit. We can cover the bottom with a metal, allowing for good conduction, but if we completely cover the top, then photons can't get through the opaque conductor and we lose all of the current (in ...
Shohini Gose quantum physicist says in her TED talk that quantum physics describes the behaviour of atoms and fundamental particles, like electrons or photons. A quantum computer operates by controlling the behaviour of these particles, which is very different from the way our traditional computers wo...
