## Do We Really Need a Battery | Physics

Hey friends! Ever wondered, what drives the current in an electrical circuit? What’s the role of a battery we get at the electrical stores. For those of you, who are really fascinated by gadgets, electrical appliances, in this video we find out that do we really need a battery in a circuit. Let’s have a

## Casual and Scientific Use of “Theory” and “Law”

Captions are on! Click CC at bottom right to turn off. Some words used casually have different meanings than when used scientifically. I’m going to give you an example. When I was younger, I noticed that sometimes after it rained, I’d find earthworms in puddles. And I’d wonder—why are these earthworms coming out of the

## Ohm’s Law | Physics

Hey friends! Do you like experimenting with electrical gadgets? Many of you must have got a scold for your parents, when you try to open a TV remote, a computer cpu, etc, in order to fulfill your curiosity to know what inside.

## Math Antics – What Is Arithmetic?

Hi, welcome to Math Antics. In this video, we’re gonna learn about Arithmetic. Sometimes when people use the word “arithmetic” they just use it to mean the same thing as the word “math” or “working with numbers”. But often, it’s used more specifically to refer to four basic math operations: addition, subtraction, multiplication and division.

## Lecture 26 – High order Derivatives From Difference Formula

But remember we are talking about finding the derivative of a function numerically that is given a set of data points, how do we find the derivative on one of this defined data points or on some other points in between and we looked at the method in which we would interpolate we will construct
