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.

The A-BOMB


One of the things some people don’t realize is that Einstein worked for the military for a time. He helped create the atomic bomb.

The Americans were not the first to come up with the idea. The Germans were. Einstein actually didn’t want to help the military in WWII at first. But in 1933 he changed his mind when Hitler rose to power in Germany. After that he talked to the president about the bomb.

The a-bomb uses a very rare isotope of Uranium called U-235. At the time it was incredibly hard to extract it though. This was mostly because it has nearly identical chemical properties to the useless isotope U-238. Making it impossible to extract the isotope using traditional chemical proses.

The concept for the bomb was from Einstein’s equation E=mc^2, which means.
In physics, in particular special and general relativity, mass–energy equivalence is the concept that the mass of a body is a measure of its energy content. In this concept, mass is a property of all energy, and energy is a property of all mass, and the two properties are connected by a constant. This means (for example) that the total internal energy E of a body at rest is equal to the product of its rest mass m and a suitable conversion factor to transform from units of mass to units of energy. Albert Einstein proposed mass–energy equivalence in 1905 in one of his Annus Mirabilis papers entitled "Does the inertia of a body depend upon its energy-content?"[1] The equivalence is described by the famous equation: E=mc^2

Shortly after the bomb was complete the Allies demonstrated its power by dropping it on Hiroshima, and Nagasaki, Japan.

Overall, this was a truly devastating weapon. It was probably one of Einstein’s biggest regrets.

recent


In this post I was going to post some thing resent about Einstein, buuut because he is alertly dead I’ll just have to post some thing resent related to Einstein. In this case some thing made possible by his threes in physics.

The worlds fastest stop watch. It works by flinging 2 special particles together. Then mishearing the specific light palsies it emits. But I think the article I got my information from explains it beater.

“ ‘Atomic nuclei in particle colliders like the LHC (Large Hadrian collider) at CERN or at RHIC (Relativistic Heavy Ion Collider) can create light pulses which are still a million times shorter than that’, says Dr Andreas Ipp, of the Institute for Theoretical Physics at TU Vienna. The proposed stop clock would be able to measure time in ‘yoctoseconds’, one septillionth of a second or 10-24 seconds. To put this in perspective, yoctoseconds are the next meaningful order of magnitude up from the time required for light to travel one Planck length, the briefest physical span of time: 10-44 seconds. So the new stop clock would be very quick indeed.”


For those of you how didn’t understand it is pity much a supercollider that can measure almost the shortest possible span of physical time. Pretty cool right? How about having that time the runners for the Olympic Games.

how to


Hello on this post I thought I would tech you some thing related to what Einstein loved to do. In this case sailing. This is a step-by-step process for folding a sail for proper storage in the winter.

1.      Rolling your sails is the best way to prevent wrinkles and crease lines in the sail. Folding the sail properly will take 2 people- one kneeling along the leech of the sail, and another along the luff.

2.      First, remove the mainsail battens from their batten pockets. Begin the folds, along the foot, both on mainsails and genoas. Pull the sail tot until all the wrinkles have bin smoothed. Fold the sail from bottom to top. While looking at the medal of the sail, place one knee on the bottom of the sail and the other about 14”-18” from the bottom. This could change with the size of the sail and how big you want it at the end.

3.      Then grab the leech at a point about the same length as you are trying fold it. Lift the material and pull it toward the bottom of the sail putting it on top of the first fold and pull it on the sides to remove any wrinkles.

4.      Repeat step 3 moving your knee gently toured the center so you don’t mess up the other folds. The material will get narrower with each fold. Carefully place each fold on top of the other ones being careful not to crease the material.

5.      Sails with plastic windows need special attentions. Fold so plastic windows lie flat in the center of a fold. Don’t let the plastic be along the middle of a crease. In cold weather, the plastic will become stiff and likely brittle. It will probably cause it to split when you unfold in the spring. Sprinkle a little a talcum powder on the plastic to prevent the plastic window from sticking to the sail while folded.
 
6.      Finish by folding the flaked sail toward the center to create a brick like shape.

I found it interesting when I learned Einstein liked to sail. I gees it mite be fun. Maybe I'll try some day.

When he was yong


Hello and welcome. Since this is my second post I think I’ll cover some of the stuff people might not know about Einstein at the beginning of his life.

Einstein actually didn't start talking until he was 4 years old. He also repeated his sentences softly for many years. He also didn't start to read until was 7, because of all this he was considered retarded, slow- witted, and possibly schizophrenic. Or so people thought.

But as a matter of fact it was later revealed in his biography by his family he actually had a relatively good understanding of the world at a young age, “The same family legend, though, reports that, at the age of 2 ½ years, when his newborn sister (a Mädle) was shown to the boy, Albert, obviously expecting a toy to play with, could already verbalize his disappointment: “But where are its wheels (Rädle)?””.

Looking back, there are a lot of misconstrued ideas about Einstein. This is largely due to the fact that not much is known about his early years. I’m really excited to see what else I learn and what will contradict or support what I think I know.
