Hydrogen atom contains single proton and electron bound by Coulomb force. Atomic hydrogen constitutes about 75% of universe's baryonic mass. Most common isotopes are protium (99.985%), deuterium (0.0156%), and tritium (12.32 years)
Spin quantum number (s) describes intrinsic angular momentum of particles. Electrons have s = 1/2, while bosons have integer values. Spin magnetic quantum number (ms) represents z-axis component of spin. Total spin and z-component are quantized, leading to two quantum numbers
Quantum is the minimum amount of physical entity involved in an interaction. Quantum is a discrete quantity of energy proportional to radiation frequency. Physical properties can only take on integer multiples of one quantum. Electrons in atoms exist only at discrete energy levels
Sergei Korolev pioneered practical astronautics and space technology. Mikhail Lomonosov founded geology and revolutionized Russian literature. Dmitri Mendeleev created the first periodic table of elements. Alexander Popov invented the radio, which is still used in modern technology
Cosmic connections are bonds that encourage personal and spiritual growth. Universe naturally brings people together in due time. These connections can be positive or negative in various relationships
The 5th dimension is a microscopic space dimension smaller than an atom. It's curved so tightly that it's closed in on itself. Estimated width is only 10^-33 centimeters. Cannot be directly observed by humans
