A Glance on Einstein's Relativity

A famous quote by Einstein on Humanity
A representation of Einstein and his theory of relativity 







So yeah, unlike yesterday we are gonna talk about a space prodigy who will never be replicated

Today we are going to talk about a sensational breakthrough in the history of Astronomy i.e,

The Theories of Relativity:

  1. Special Relativity 
  2. General Relativity 
So let's start with a brief introduction on it

In 1905, at the ripe age of 26, working in a patent office, 
He produced the 5 papers that made the universe to get a new look, a lot more different than the ideas by Newton and others like static time. 
Those 5 influential papers were:

  1. General Theory of Relativity 
  2. Spacial Theory of Relativity
  3. Brownian Motion
  4. Photoelectric Effect 
  5. Mass Energy Equivalence
These papers changed the course of history

Let us study 'Theories of Relativity' in detail

  1. General Theory of Relativity
Einstein proposed that objects such as the sun and the Earth change this geometry. In the presence of matter and energy it can evolve, stretch and warp, forming ridges, mountains and valleys that cause bodies moving through it to zigzag and curve. So although Earth appears to be pulled towards the sun by gravity, there is no such force. It is simply the geometry of space-time around the sun telling Earth how to move. 
The general theory of relativity has far-reaching consequences. It not only explains the motion of the planets; it can also describe the history and expansion of the universe, the physics of black holes and the bending of light from distant stars and galaxies.

   2. Special Theory of Relativity

Einstein’s special theory of relativity tells us how the Universe looks to
an observer moving at a steady speed. Because the speed of light is the samefor all such observers, moving clocks run slow, moving rulers shrink, andmoving masses become even more massive
An example of it is the famous twin's paradox in which a hypothetical pair of twins are there in which one goes to space through a spaceship at 50% of speed of light
And the other twin stays on Earth 
After a day of travel for the spaceship twin the twins meet 

 But the interesting part is the Earthly twin is 63 years and the other is only 2 days old
This is called the twins paradox which in simple words means that time slows down when velocity increases

 That's it for today

God Doesn't Play Dice

Hello Guys and welcome back to my blog !!! Today we are going to talk about a huge controversy on Science during 1920s...   Albert Einstein   is one of the greatest and certainly best known physicists. If you ask anyone to name a physicist the most common answer you will receive is “Einstein”. Einstein is also famous for his quotations. Among the many Einstein’s quotations one is particularly popular among the general public: “God does not play dice”. But what did Einstein mean by this? The quotation says, “Quantum theory yields much, but it hardly brings us close to the Old One’s secrets. I, in any case, am convinced He does not play dice with the universe.” It was addressed by Einstein to Max Born (one of the fathers of Quantum Mechanics) in a letter that he wrote to Born in 1926. The “Old one” and “He” Einstein refers to is God. The fame of this quotation stems from two sources: 1) Einstein’s disagreement with the fundamental concept of Quan...

Antimatter - The Long Lost Cousin of Matter

A beautiful quote by Paul Dirac Many of you physics lovers would have figured out what I am gonna talk about Yes, The contrary to matter - Antimattter So now let's have a brief insight about it Antimatter: Classical physics only allowed systems to have positive energy. But Dirac’s new theory of relativistic quantum mechanics allowed for a particle with negative energy solution, as a counterpart to the familiar positive-energy electron. After ruling out the possibility that this particle was simply the proton – which has a hugely greater mass – Dirac predicted the existence of a new particle with the same mass of the electron but with a charge that was positive rather than negative. It’s now understood that all particles have an equivalent antimatter particle with opposite charge and quantum spin – although some are their own antiparticle. However hardly any antimatter is seen in the observable universe, and why there should be vastly much more normal ma...

The duo of Waves and Particles

Hello guys and welcome back to my blog Today we are going to answer a question aboout explaining particle wave duality So hold tight and off we go Particle wave duality : Publicized early in the debate about whether light was composed of particles or waves, a wave-particle dual nature soon was found to be characteristic of electrons as well. The evidence for the description of light as waves was well established at the turn of the century when the photoelectric effect introduced firm evidence of a particle nature as well. Wave-particle duality , possession by physical entities (such as  light  and  electrons ) of both wavelike and particle-like characteristics. On the basis of experimental evidence, German physicist  Albert Einstein  first showed (1905) that  light , which had been considered a form of  electromagnetic waves , must also be thought of as particle-like, localized in packets of discrete  energy . The observations ...
