How does an aneroid capsule work?

How does an aneroid capsule work? Inside an aneroid barometer is a small capsule. This capsule has had the air pumped out of it. When the air pressure rises, the sides of the capsule are compressed. The capsule is attached to levers which move a needle as the air pressure squeezes the capsule. What is […]

Who said light is a particle?

Who said light is a particle? Einstein Who discovered the particle nature of light?

Heinrich Hertz discovered experimentally the existence of electromagnetic […]

Why is U-235 better than u 238?

Why is U-235 better than u 238? The U-238 nucleus also has 92 protons but has 146 neutrons – three more than U-235 – and therefore has a mass of 238 units. The difference in mass between U-235 and U-238 allows the isotopes to be separated and makes it possible to increase or “enrich” the […]
