In Bohr’s 1913 papers he envisaged atoms along the lines established by his mentor Ernest Rutherford: dense nuclei orbited by ...

the Bohr–Sommerfeld model provided a set of rules for selecting certain ‘allowable’ orbits of a classical system (in the case of the hydrogen atom, an electron orbiting a proton), delivering ...

Electrons are chaotic and show duality, so they don’t typically behave in an orderly way.

Thus when an atom absorbs or gives off energy (as in light or heat), the electron jumps to higher or lower orbits. Bohr published these ideas in 1913 to mixed reaction. Many people still hadn't ...

Polar orbits take the satellites over the Earth’s poles. The satellites travel very close to the Earth (as low as 200 km above sea level), so they must travel at very high speeds of nearly 8,000 ...

Examples of artificial satellites orbits include: polar orbits; geostationary orbits. Polar orbits take the satellites over the Earth’s poles. The satellites travel very close to the Earth - as ...
