Hi welcome back. So far
I have covered a narrow spectrum of Einstein’s life. So this time I
would like to cover what I think are his greatest accomplishments.
Counting down from #5.
#5. Partial lite
theory
This was important I
think it opened all kinds of new doers for physics. It pretty much
sates that lite travels in partials not just waves.
“In 1905 Albert
Einstein had proposed a solution to the problem of observations made
on the behavior of light having characteristics of both wave and
particle theory. From work of Plank on emission of light from hot
bodies, Einstein suggested that light is composed of tiny particles
called photons, and each photon has energy. Light theory branches in
to the physics of quantum mechanics, which was conceptualized in the
twentieth century. Quantum mechanics deals with behavior of nature on
the atomic scale or smaller. As a result of quantum mechanics, this
gave the proof of the dual nature of light and therefore not a
contradiction.”
#4. Why the sky
is blue
Here is a question
people have been asking for centuries. Einstein finely figured it out
cool right. It is pretty much caused by how the lite reflex off the
particles in the atmosphere until the lite hits our eyes. The logger
wavelengths pass state throw the atmosphere, but the shorter blue
ones get bounced arrowed till they reach our eyes.
#3. Nobel prize
In 1920 Einstein won
the Nobel physics prize. Although it was not for his most fames
equation or theory of relativity. Instead it was for his particle
lite theory. This was due to the fact that so few people understood
it at the time few people still do. It was a good thing he got it to
his kind from his divorce wife lived in Switzerland just after WW2
and they needed the money to survive.
#2. E=Mc^2
I have actually talked
about this in one of my previous post “The A-bomb” for technical
refrains go there.
This equation was one
of the many things that came to Einstein in his dreams.
#1. Theory of
relativity
This was definitely
Einstein’s greatest accomplishment. This theory completely changed
how we looked at the universe. It clams space and time as one object
not two. The theory describes them as a fabric and gravity as an
effect caused by mater. Like putting a marble on a taunt fabric the
bigger and heaver the marble the grater the distortion or
gravitational pull.
“An important
aspect of Einstein's theory of relativity to note is that he proposed
matter causes space to curve. If we pretend that "space"
is a two-dimensional sheet, a planet place on this "sheet"
would cause it to curve (see diagram below). This curvature of space
results in what we perceive as gravity. Smaller objects are
attracted to larger ones because they "roll" through the
curved space towards the most massive objects, which cause the
greatest degree of curvature. In relation to time, this curvature
causes the gravitational time dilation effect. Under normal
circumstances, this effect is impossible to observe. However, in the
presence of the extremes of our universe (such as black holes, where
a huge amount of matter is compressed into an extremely small
volume), this effect becomes much more obvious. To a distant
observer, an object falling into a black hole would appear to never
reach it, due to time dilation causing time to "progress"
extremely slower, at least relative to the distant observer (the
object in question, however, would very rapidly be destroyed by the
black hole).”
These 5 are just a few
of his many accomplishments. Einstein has contributed greatly to the
ideals of modern physics. All though that’s not all he has done I
just can’t think of anything ells right now.
