Einstein’s Greatest Mistakes: 1st Anniversary Special Post!!!

Well…Einstein…we
all know about him!!!

His contribution
in physics was so great and influential that it is directly responsible for the
creation of a completely new field in physics. He helped us to solve problems
like mercury’s orbit and his theory of relativity helped us to understand black holes. For his theory of relativity, today we all are enjoying various services
from the satellites. Well, if that’s not enough….his joint paper with Satyandra
Nath Bose, the Bose-Einstein Statistics directly helped in the creation of
today’s Quantum Mechanics. And consequently, he became the Time’s Person of the
Century for the 20^th century.

It’s hard to
imagine that such a person made some serious mistakes in his field but, as they
said “Facts are Stranger than Fiction” and this case is not an exception. So,
are you ready to dig into this???

Well, before
starting, I want to thank everybody who consistently visited my blog and gave
their valuable suggestion to me to improve this blog. For the last 1 year, I am
just trying to enrich the knowledge of people without any cost. The motto,
target and enthusiasm is still the same as it was in day 1 and it will remain the same for
coming years!!!

So, let’s dig into
this article….

1) Adding Cosmological
constant (Λ):

This was a
great mistake. The gravity of this was so much great that the Einstein himself referred this as his greatest mistake. Initially, Einstein thought that the universe was
static and unchanging. But, his equations constantly showing that it wasn’t. To
rectify this error (which is actually correct), Einstein added cosmological constant
in his equation of relativity. This rectification was unstable anyways as a
slightly denser region than the normal would collapse and slightly less dense
region would expand. That means everything should be perfect.

If Einstein didn’t
add that constant then he would predict the expansion of the universe before
Friedman and Lamaitre and before Hubble found the evidence of it.

Later,
Einstein rectify his mistake and removed the cosmological constant from the
equation.

2) Accepting
Gravitational Waves:

Although, Einstein
predicted the gravitational waves in 1916 but he believed that they would be
incredibly hard to measure and also doubted the existence of the black holes
that may be causing them.

But, scientists
of LIGO detected gravitational waves successfully for the first time in 2015,
about 100 years after Einstein’s prediction.

3) Rejecting
Quantum Mechanical model:

Einstein
contributed significantly in the field of quantum mechanics by developing theories
like the photoelectric effect and developing mathematical structure like
Bose-Einstein statistics. Even Einstein won Nobel Prize for photoelectric
effect.

4) Einstein’s
wrong approach to find Unification theory:

Unification
theory or Grand Unification Theory is theory by which all of the forces and phenomena
of nature can be explained by using few simple rules, equations and parameters.

For example,
Maxwell’s law unifies both Electric and magnetic forces and forms
Electromagnetism.

Ever-since, we
all are trying to unify all those forces and Einstein was no exception.

In the last
years of his life, he tried to unify electromagnetism and gravitation. Many
experiments revealed various new rules but, Einstein ignored all those. Even it
was also showed that the strong nuclear force can be unified with
Electromagnetism and weak force. This unification can be seen in the current Standard Model. But, Einstein decided to stick with gravity and electromagnetism and try
to unify those without using new rules which results in failure.

Today, the scenario
changed. Grand unified theory now can be explained by various theories like
String theory. But, still, those are yet to be proven.

5) Einstein
simple mistake in the derivation of E=mc^2:

After reading
this heading, you probably thinking that I have lost my mind. But believe me, I
haven’t …..

It is
absolutely correct that Einstein derived E= mc^2. But, the strange truth is
that he derived it for only rest particle only. In other words, you can say
that his derivation meant for frame-dependent observation only. It is hard to
believe that he did this even after setting the laws for relativistic phenomena
in his Special Theory of Relativity paper.

It wasn’t six
years later, when Nobel laureate Max Von Laue showed that one must remove the
idea of kinetic energy to fix this error and by this way ultimately fixing the
error.

It is hard to
believe that even geniuses like Einstein made some critical mistakes but, at
the end we should remember that they are also humans and humans make mistakes.

At last, I
again want to thank all of you who stayed and supported me for last one
year. Thank you very much!!!
