Before look at genetic algorithms, what is an algorithm? I know folks from non-computer science backgrounds maybe don’t have a clear idea about that(maybe Iam wrong). In a nutshell, an algorithm is a list of instructions and rules that a computer needs to do to complete a task. In essence, Algorithms are simply a series of instructions that are followed step by step, to do something useful or solving a problem. You could consider a pudding recipe as an algorithm for making a pudding. Algorithms are found everywhere, but we don’t quite notice them.

With the spread of the Covid 19 virus, epidemiology became an increasingly popular topic among scientific communities. In epidemiology, It is vital to understand the spread of an infectious disease like covid 19. There are lots of advanced mathematical models to predict and understand the spread of infectious diseases. Here let's discuss and implement a simple mathematical model called the “SIR model” to understand the spread of a disease through an initial population. The idea behind this article is to show you that, how mathematics(ultimately Calculus) is utilized in understanding the spread of disease.

SIR Model Intro

When it comes to epidemic modeling…

In this article, let’s talk about how high energy physics research revolutionized the field of computer science. But before that let’s look at the Standard Model of Particle Physics.

The concept of Atom

The concept of the atom goes back to 460–370 BC. When the greek philosopher Democritus described his theory of the atom. His theory proposed that everything in the physical world is composed of tiny particles that are small hard spherical particles called atoms and are indivisible. He believed that the world buildup with two realities, atoms and void. It is very interesting and unbelievable that he had the fundamental idea of…

What are viruses?

The virus is a microscopic organism ( parasite), exit almost everywhere on our planet. All viruses are parasites. They can infect humans, animals Plant, fungi and even bacteria which means all types of life forms can be infected by a virus. Some viruses are deadly but some aren’t.

Viruses are much smaller than bacteria. Think of a virus as a tiny package jacketed in a protein coat. Viruses contain either RNA or DNA or both. Every molecule inside of a virus has an instruction book full of genetic information that provides instructions to host cells to what…

Have you ever thought how the spaceships, space probes and the satellites get the electricity? At a glance, it is like by batteries or by a solar panel. But do you think that all the spaceships are getting proper sunlight throughout the journey? No, As an example, space probes like Voyager and Cassini are not getting sunlight for a long time more often. Mostly in deep space nothing is boundless.
