[Sci-Tech] What is a Red Tide?

A "red tide" is a common term used for a harmful algal bloom.

• Harmful algal blooms, or HABs, occur when colonies of algae—simple plants that live in the sea and freshwater—grow out of control while producing toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. The human illnesses caused by HABs, though rare, can be debilitating or even fatal.

[Science] Chemistry Basics

Chemistry is the study of the composition, structure, properties and change of matter [matter is defined as anything that has rest mass and volume (it takes up space) and is made up of particles]. Chemistry is chiefly concerned with atoms (a basic unit in chemistry) and their interactions with other atoms.

Atoms
The atom is a basic unit of matter that consists of a central nucleus surrounded by negatively charged electrons. Nucleus contains protons and neutrons. Electrons revolve around the nucleus in different orbits.

[Science & Technology] Gravitational Waves, General Relativity etc

1. What are gravitational waves?

Answer: Gravitational waves are ripples that carry energy across the universe. They were predicted to exist by Albert Einstein in 1916 as a consequence of his General Theory of Relativity. Although there is strong circumstantial evidence for their existence, gravitational waves have not been directly detected before. This is because they are minuscule — a million times smaller than an atom. They are like tiny waves on a lake — from far away, the lake’s surface looks glassy smooth; only up very close can the details of the surface be seen.
Particularly exciting are “primordial” gravitational waves, which were generated in the first moments of the universe’s birth. These carry vital information about how the universe began.
