Physics – What is the Archimedes’ Principle?

Say you have a beaker filled with water and you put your index finger inside it. You’ll observe that the water level rises slightly. You put in two fingers, the water level rises a bit more. And now when you put in your hand up to the wrist level, you’ll see that the water level […]

Maxwell’s Equations: Crash Course Physics #37

By the 19th century, we were pretty sure there was something was going on between electricity and magnetism. First, in the early 1800s, Michael Faraday showed us how a changing magnetic field induces an electromotive force, or emf, resulting in an electric current. He also found that electric fields sometimes act like magnetic fields, and […]

Mod-01 Lec-10 Elemental Semiconductors

Today, we shall discuss about the Elemental Semiconductors. You know that the electronic materials are mostly semiconductors and it can be categorised into a large number of materials; practically it is a material family. And, broadly we can divide semiconductors into two groups; one is the elemental semiconductor, another is the compound semiconductor. So, one […]

#withC8 – Puerto Rico Generator

With C’8, a friend of mine in Puerto Rico would have been able to enter the data for her mother’s need for a generator, a medical need for a generator that went out several weeks after the hurricane and after the loss of power. It was something of a medical emergency, something of a serious […]

Vectors and 2D Motion: Crash Course Physics #4

So far, we’ve spent a lot of time predicting movement: where things are, where they’re going, and how quickly they’re gonna get there. But there’s something missing — something that has a lot to do with Harry Styles. And today, we’re gonna address that. We’ve been talking about what happens when you do things like […]

Physics – Do Liquids exert Pressure?

A Wooden block kept on a table exerts a force on it, and we know that the wooden block is a solid substance. What about liquids? We know that liquids are kept in containers. Do liquids or fluids exert pressure? Yes, they do. They exert pressure on the base and the walls of the container […]

Redefining the Kilogram with the DIY Watt Balance

A meter is defined as the distance traveled by light in 3 billionths of second. A second is defined as the time it takes for about 9 billion cycles of radiation of the cesium atom. But the definition of the kilogram is a little bit more approachable: it’s literally the mass of a particular chunk […]
