Michael Farday: The Self-Educated Inventor

Tue, 23 Jun 2020 00:00:00 +0000

Michael Faraday (1791 - 1867)

Is it possible to become one of the most influential scientists in history without a formal education? In the case of Michael Faraday, the answer would be an absolute yes. Our world is full of big and small electric motors. And we owe Faraday for discovering the principles of electromagnetism that led to the first electric motor.

Faraday’s main contributions were within the study of electromagnetism and the relationship between electricity and chemical change. His work helped develop the generators we use today. He also devised the commercial process of separating elements from their ores, such as iron. Faraday named this process electrolysis. Without him, the use of electricity in technology would have been severely delayed.

How many times have you seen milk boil and spill over, and wondered why this happens? To answer this question we have to know a little more about the composition of milk.

Milk and its composition
Unlike water, milk is not a simple liquid. It is a colloid and contains many substances in suspended form. These substances are mainly protein, sugar and fat. When milk is heated slowly, the proteins and fat get separated. Since they are lighter than the milk they collect on the surface in the form of a layer called cream.

One of the earliest memories I have as a child is when I was approximately three or four years old. I remember watching my mother work in the kitchen. She was cutting onions for the salad and I could see tears in her eyes. For a child the worst possible thing is to watch his/her mother cry. I got so upset that I got hysterical at my father for causing her pain. For I assumed my father was somehow responsible as we were only the three of us in our family.

How do you make tea? Simple, put a teaspoon of tea into a boiling cup of water. Strain the water, pour some milk and sugar to taste and the tea is ready! Interestingly, everything that we prepare has a recipe and is made up of simpler ingredients.

For example, what is sugar made of? It is made of sugar molecules, which in turn, are made up of atoms. The atom is the building block of all substances.
