Relativity theory is one of the most famous theories to science. It was discovered by Albert Einstein. Nowadays it is used as the base for space-time and the explanation to some of the most common yet complicated questions. Here I will explain about how it works and its history and controversy. Its discovery was made in 1905 and a space probe designed specifically for the proving of this theory confirmed it. On discovery, many other scientists rejected the theory as they thought it was overly far-fetched and worthless. However, over time this theory gained popularity. After all, it still complies with all the normal laws of physics. The point of the theory is that all time and speed are relative to the person measuring it. For example, if in the USA it is midnight, then in Russia it would probably be noon. Similarly, a person measuring the speed of a tree on the ground would measure it as 0. However, if this person were on a bus instead, he would measure the speed as the inverse of...

Hello there! This time my blog will discuss about Tesla Coils, its origin and how they work in the first place. Tesla Coil was invented by Nikola Tesla in 1891 – that’s why the device has his name, and was shown in a presentation by him. Scientists were amazed by this eye-opener invention. Nikola got the idea from an 1826 invention that could amplify electricity via a wire current. He improved this idea and magnified it as to have the complete setup for a modern amplifier. To this day, it is used as an alternative for an amplifier. However, now there are other electric amplifiers that may be more effective. The Tesla Coil is very famous for being able to easily discharge massive amounts of electricity in a short amount of time. The device has the ability to reach discharges of several million volts. Many scientists use this coil to release electricity into the air for experiments, entertainment, museum exhibitions, and special effects. Some even create a mini Te...

This is part 2 of the Math Calculations: Simplified blog. Welcome back! This time I’m going to share tricks about counting squares such as 41 2 or 52 2 .  There are 2 simple methods that I am going to explain. Here is the first one: METHOD  1 For numbers that begin with 1, the formula is simple:  (N-1)²+ (2N-1).  For example, let’s calculate 51². The equation becomes (50)² + (101). It is now easy to figure out the solution, which is 2601. This method makes it much easier to do these types of calculations rather than using the traditional method of carry-multiplying. Next, we have the 2 digit numbers that begin with 9. We can figure this out by using pretty much the opposite of the method used to calculate the square of one digit numbers. The formula: (N+1)² - (2N+1). Let’s use 29² as an example. We put this into the equation, which makes it (30)² - (59). That leads to a solution of 841. This method also helps with these types of calculations. ...

In Math, calculating numbers can indeed be quite annoying for some students. For example, you are doing a math test and end up spending too much of your precious time calculating 51 ² or √67. Fear not, for I have a quick and easy solution in squaring and square-rooting numbers. Just a quick reminder, N in the methods stated below means the number you are trying to square or square root. Let’s start with squaring 2 digit numbers and the ones that end with 0. These numbers are simple to be squared because all you have to do is to square the first digit then give two zeroes in front of it. Pretty simple, right? Here’s an example: 30². We can calculate this by first giving 3², which is 9, then give two zeroes in front of it, which makes it 900. Easy peasy! Conclusion, 30 x 30 = 900   à   3 x 3 = 9 and 00 = 900 Another example :           80 X 80 = 6400 And                 ...
