Radioactivity
Radioactivity is the process in which an unstable atomic nucleus loses energy by releasing radiation in the form of particle or electromagnetic waves. During radioactive decay, an atom emits specific types of radiation, which vary in factors like mass and charge. There are three types of radiation that are released: Alpha Particles: This type of…

UV and IR Light
Ultraviolet(UV) light and Infrared light(IR) are two forms of invisible electromagnetic radiation which are on opposite ends of the visible light spectrum. UV light has high energy and a shorter wave length making it suitable for sterilization (the process of removing all forms of microbial life) and IR light which has a longer wavelength and…

Nanorobots in Medicine
Nanobots are some of the smallest types of robots which can be used for medical purposes and are made to navigate the body at a cellular level. They usually range from 0.5 to 3 micrometers in size. They offer precision in performing delicate surgery, diagnosing diseases and transport drugs to affected tissue without affecting any…

Paraboloid
A paraboloid is a curved 3 dimensional figure with no center of symmetry but one axis of symmetry. The name paraboloid is derived from the word, parabola which is a symmetrical, U-shaped curve. There are 2 types of paraboloids: an Elliptic paraboloid and a Hyperbolic paraboloid. Elliptic paraboloid: This type of paraboloid looks like a…

Hunting Exoplanets
“What is outside our solar system” Exoplanets are the distant planets outside our solar system. Hunting exoplanets is the search for planets orbiting stars outside our solar system. Astronomers rely on clever techniques—most notably the Transit Method (watching a star dim as a planet crosses its face) and the Radial Velocity Method (measuring a star’s…

Dimensions: Part2- Living in every dimension
“How would life look like in every dimension” The part1 of “Dimensions” consisted of what every dimension is from 0d to 5d, but what would it be like to live in every dimension. Dimensions are measurable extents of a physical space. In each dimension, time and space would have different properties. Right now, we live…

Dimensions- 4D and 5D figures
“Are there 4d and 5d figures?” In our surrounding we usually see 3d figures. We usually draw 2d figures. A line is 1d and a dot is 0d, but are there 4d and a 5d figures? First, a dimension is a measurable extent of a specific kind, such as length, width, height, or depth. More…

Mobius Strip
“A 2-in-1 loop” Have you ever thought of such a loop that requires you to reach the same point after travelling twice? Well, here is the mobius strip. In mathematics, a Möbius strip, Möbius band, or Möbius loop is a surface that can be formed by attaching the ends of a strip of paper together with a half-twist. As a mathematical object, it…

Dark matter
Dark matter is an invisible form of matter that does not interact with light or other electromagnetic radiation. Originally known as the “missing mass,” dark matter’s existence was first inferred by Swiss American astronomer Fritz Zwicky, who in 1933 discovered that the mass of all the stars in the Coma cluster of galaxies provided only about 1 percent of the mass…

Matter vs Antimatter
Matter is what makes up everything. Matter is made up of small particles called atoms. There are two different forms of matter in the Universe- matter & antimatter. Both matter and antimatter are equal in mass but opposite in charge. Matter consists of protons, neutrons, electrons, quarks and leptons. Antimatter is composed of antiquarks, antileptons,…
