Einstein greatest 5 accomplishment


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.

Final post


Hi everyone, this is my last post. So I thought that I would look over things from my previous post and about making a blog. I thought that I would just rap it all up.

What I learned while bloging


Most confusing of all
The most confusing things I talked about were the Theory of relativity and E=Mc^2. Both dealt with complex ideas describing the universe that we don’t fully understand still. Even though we know the relativity theory deals with space, time, gravity and more, and E=Mc^2 deals with the relation of energy, mass, and the speed of light.

A few fun facts and good quotes
I learned some interesting little fun facts about Einstein when I was doing my research. I also found a lot of good quotes that make a lot of sense to me. Actually here are a couple of links you can check. “Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.”

Hardest part of blogging

Finding resources
The hardest part of writing this blog was finding strong reliable resource of information for what I needed. There are a lot of websites and blogs out there with unreliable information plus not a lot is known about Einstein’s early days.

Writing
After you get your information the next real challenge is what are you going to say. I mean you have the facts but how are you going present them to the readers. Getting an idea is easy sometimes but following through is so much harder.

Rewords of completing a blog

Being done
It feels great to say I’m done. I have my research, I’ve written it out, and it flows smoothly. I am done. The feeling of a finished task is great. But it can get even better.

Praise
When someone compliments you on your work and really means it, that is the best. That feeling drives you to do better, and push harder the next time. When you are complimented on a job well done and you know you worked hard, it is the greatest of feelings.

Overall making this blog has been kind of fun. I feel I have a new respect for writing and for old Albert. But to be honest I hope I never have to do anything like this ever again.

Two bombs of a thery


Welcome back to E=Mc^2. Last time we talked about the A-bomb. So this time I want to compare it to another weapon created with Einstein’s Theory of relativity, the H-bomb.

First I think we’ll look at the A-bomb a little more closely. Last time we learned that the A-bomb used a rare isotope of Uranium U-235. Now let me explain why. U-235 is an unstable isotope witch makes it easier to brake. You see most nuclear bombs use fission the splitting of atoms. When this happens the exes mass is transformed into energy resulting in an explosion. This is a quote describing the blast.
The brilliant light from the detonation pierced the early morning skies with such intensity that residents from a faraway neighboring community would swear that the sun came up twice that day. Even more astonishing is that a blind girl saw the flash 120 miles away.”

WOW right, but now let’s talk about the H-bomb. Unlike the A-bomb the H-bomb uses fusion. Witch is the nonbinding of atoms to make new heaver atoms. But the leftover mass is still converted to energy. Do to the immense heat rewired for fusion the destructive power in terms of physical forces is even grater then the A-bomb. It is also how the H-bomb got its nickname the thermonuclear bomb.

Fusion and Fission aren’t the only deferens between A and H bombs.
Since the fusion reaction produces mostly neutrons and very little that is radioactive, the concept of a "clean" bomb has resulted: one having a small atomic trigger, a less fissionable tamper, and therefore less radioactive fallout”
The lasting radiation from the A-bomb causes more physiological and environmental damage in the long run.

Even with these defenses there are some similarities like,
Like other types of nuclear explosion, the explosion of a hydrogen bomb creates an extremely hot zone near its center. In this zone, because of the high temperature, nearly all of the matter present is vaporized to form a gas at extremely high pressure.”
Also both use the energy formed from exes mater witch is the forces behind the explosion.

Both of these bombs were formed using some of Einstein’s equations. I was interested to see the direness in the effects of both bombs bout immediate and lasting. It’s sad that a theory meant for peas could be used to blow cites to peaces.
