The meaning behind the most famous equation ever = E=mc^2

E=mc^2

We all have heard of the equation E=mc^2. In fact, whenever we think of equations, this equation comes in our mind first. But what exactly does it mean? We'll dive into this topic today!

The equation  E=mc^2 was first proposed by the world renowned scientist named Albert Einstein. E =mc^2 is the same as m=e/c^2. I know these equations look so large and confusing at first, but we'll soon know it.

This equation tells us that energy and mass are the same. This equation allow us to convert mass into energy. 

E=energy
m=mass
c=the speed of light
In the equation, E stands for energy, m stands for mass, and c stands for the speed of light(which is approximately 300,000 km or 180,000 miles!). But here it says c^2,  which means speed of light squared or multiplied by itself.  To get the energy of an object, we should multiply the mass of the object to the speed of light  and multiply the product by itself. 
To multiply the mass by the speed of light, the standard unit of both mass and speed of light must be the same. For instance, if the mass is multiplied in kg, then the speed of light should be measured in km.
The reason behind why mass must be multiplied by the speed of light to get energy is that the pure energy in a mass is an electromagnetic radiation and any electromagnetic radiation is light. So, the speed of light tells the amount of energy present inside any object. Exciting, isn't it?

Report on Ancient Clocks and the Measurement of Time Through the Ages

  Report on Ancient Clocks and the Measurement of Time Through the Ages Introduction The measurement of time is one of humanity's oldest and most fundamental activities. From the earliest days of civilization, humans have sought ways to track the passage of time, both for practical purposes like agriculture and for more abstract concepts such as religious rituals. This report explores the evolution of timekeeping devices and methods, from ancient times to the development of modern clocks. 1. Early Methods of Timekeeping 1.1 Sundials The earliest known method of time measurement was the sundial, which dates back to ancient Egypt around 1500 BCE. Sundials work by casting a shadow on a flat surface marked with lines indicating the hours. As the sun moves across the sky, the position of the shadow changes, allowing people to tell the time. Sundials were widely used in ancient Greece and Rome and remained popular until mechanical clocks were developed. 1.2 Water Clocks (Clepsydra) Water...

Must know tips before making a blog!

  Making a blog is not as easy as you think it is. There are many obstacles that you must face to bring up your blog. I started my blog a month ago, and it took me a whole month to understand the secrets to increase the traffic of my blog. Here are some tips that may be useful to you while making a blog: 1. Choose an SEO friendly blogging platform You need to use an SEO friendly blogging platform to make it come to google quickly. According to me, the best example of this is Wix. Wix is not only a website/ blog building platform, but also SEO friendly. It took my Wix website only around 11 days to come to google, while my google sites website is yet to be indexed by google. Currently, I am using blogger as my blogging platform, but to my disappointment, it is not the first website to come in google search. So, if you are planning to start a blog, you can use Wix or Wordpress if you want a really good output. 2. Choose your goal While making a blog, you must know the reason behind w...

Why is the sky blue?

  Why is the sky blue? This is the most common question most of us have heard of. The sky is blue in the morning and red in the evening. Why is that so? In this post, we will get to know about it! In this image,  we can see that the sky is entirely blue with white clouds. And in this image, we can see that the sky is reddish pink. All these beautiful phenomena occur because of a specific reason.  The sun is 93 million miles away from us. The light from the sun takes 8 minutes to reach here. The light has to enter the atmosphere to reach us. We know that the atmosphere is composed of many gases and particles.  These particles act as an obstacle for the light of the sun as it enters the atmosphere. They make the light to scatter here and there, resulting the light to appear blue . Wait, how does that happen? For that, we have to take a look at the light spectrum! Have you seen a rainbow? Doesn't it look colourful? Rainbow is formed when waterdrops break the light of th...
