Orders of Magnitude
The Order of Magnitude of a number is an approximation of its logarithm. Simply put, the order of magnitude tells us the scale of a number. Whether it is in the tens, hundreds, thousands, millions, and so on, or in […]

Hulse-Taylor Binary [PSR B1913+16]
The Hulse-Taylor Binary is a pair of neutron stars in the region of the Aquila constellation as viewed from Earth. Even though the neutron stars of the Hulse-Taylor Binary orbit one another at a distance about 30% greater than the […]

In QFT all particles are considered as “excitations” that form from the underlying fields of physical reality. In essence, particles — the base “material” of physical reality — emerge from a nonphysical source. Paul Dirac, a British mathematician and physicist, […]

Dimensional Analysis
Dimensional Analysis is a technique used in physics, chemistry, engineering, and science in general to track the dimensions of all physical quantities while performing calculations. The purpose of this practice is to ensure our final value is accurate in that […]

The universe is filled with cosmic objects and dynamics that have no counterpart on Earth. In a literal sense, beyond the Earth is an alien reality, filled with alien worlds, objects, phenomena, events and dynamics that defy the imagination in […]

Radio Waves are a range of frequencies within the spectrum of light — a type of electromagnetic radiation (EMR) — found throughout the world. They are generated whenever a charged particles are accelerated, thus there is radio noise that results […]

The Messier Catalogue (pronounced Meh-see-ay) is a catalogue of cosmic objects published in 1781 by the French Astronomer Charles Messier. These deep-space objects are non-stellar (i.e. not stars) and are well beyond our solar system. Over more than two decades […]

Today we measure Star Brightness with a system that was invented by the great scientist, mathematician, and astronomer of Ancient Greece — Hipparchus. Hipparchus was truly ahead of his time. In my opinion, relative to the level of knowledge, skills, […]
