IRC Bouncer on a Pi
Internet Relay Chat is one of the original forms of social media. It was once the go-to destination for socializing with online communities. IRC has been around the 80’s and isn’t going to fade away any time soon. The way IRC works is similar to a typical client-server model. IRC servers are hosted all around the globe by many universities, individuals and ISPs. These servers may be organised under ‘networks’. Each IRC network hosts many ‘channels’ which are chat rooms, groups, multi-user conferences, however you may put that. Users use their IRC clients to connect to one of the hundred …

The Power of Enzymes
Biological catalysis was first recognized and described in the early 1800s, in studies of the digestion of meat by secretions of the stomach and the conversion of starch into sugar by saliva and various plant extracts. Louis Pasteur had concluded that fermentation of sugar into alcohol by yeast is catalyzed by ferments. Enzymes are bio-catalysts mostly made up of proteins (except ribozymes), which increases the rate of bio-chemical reactions by lowering down the activation energy. They were first isolated and discovered by the German chemist Eduard Buchner. The enzyme that he had discovered was zymase obtained from yeast. The term enzyme however, was given by the German …

Fertilization: A Key to Your Existence
Fertilization starts just after the transfer of gametes takes place and ends with the formation of zygote, which then differentiates to form your physical self. It is not just the fusion of the nucleus of a sperm with that of an ovum, but a sequence of events that takes place even before the sperms reach the ovum.

The Mystery of Aurora
Although they look elegant and calm, aurorae are produced when a large number of charged particles undergo collision while being trapped in Earth’s magnetic field.
This splendid display of colours and appearance of dancing lights is fascinating, and equally puzzling. These haunting lights are a form of intense space weather, a result of the atmosphere shielding the Earth against fierce solar particles that would otherwise make our planet uninhabitable. Millions and millions of electrically charged particles in the solar wind wash over Earth and smash into upper atmospheric gases. The energy from each collision is released as photons – particles of light. This causes the particles to glow.

A Physical Pendulum Problem
About 2 weeks ago, Former MIT Professor Walter H. G. Lewin posted a Physics problem on his YouTube channel as a part of his series of problems for the viewers of his channel. This question was divided into two parts – the first one, which was quite simple and a trickier sequel to it. The videos have been embedded and the solution is derived along the problem.

Alcohols and Phenols
Alcohols and phenols are formed when a hydrogen atom in a hydrocarbon, aliphatic and aromatic respectively, is replaced by –OH group. From the ordinary spirit used for polishing wooden furniture is chiefly a compound containing hydroxyl group, ethanol, to the sugar we eat, the cotton used for fabrics, the paper we use for writing, are all made up of compounds containing hydroxyl (-OH) groups.

The Father of Genetics
Gregor Johann Mendel was the first to demonstrate the scientific basis of inheritance and variation by conducting hybridisation experiments. He is best known today for his work on Pisum sativum (Garden pea) and proposal for the laws of inheritance in living organisms.
