What did albert einstine invent?

Answer 1

Einstein was a theoretical physicist and not an inventor. He gave us the special and general theories of relativity, and he did some important work on the photoelectric effect. He did invent some inventions, like the Einstein calculator. He also invented the Einstein refrigerator, which University of Oxford scientists are now investigating in their efforts to develop energy efficient, eco-friendly refrigeration. The Einstein refrigerator used no moving parts, no electricity or harmful gases. Einstein also had the idea to make the atomic bomb in the united states. So, we were the first country to make and use the atomic bomb. Although that isn't really an invention, it is useful. The atom bomb was not invented by him, the formula or say theory required for its invention was first observed by him.

Answer 2

Albert Einstein was not an inventor. He was primarily a physicist. He did create some excellent models for understanding our Universe (large and small scale).

1. Special Relativity. Einstein created this model to explain the Universe under the newly discovered fact that light travelled at a constant speed. In other words, light speed was absolute. If you were in a car on the highway, and saw a light at the side of the road as you approached it, the light would approach your car at the same speed as it would approach someone stopped at the side of the road. This doesn't sound too groundbreaking, but it has some weird consequences. You've probably heard of the twins where one travelled into space and the other stayed on Earth, and when the space-travelling twin came back he/she was much younger than the other. That is because time travelled slower for that twin, since his/her speed was closer to light speed than the Earthbound twin.

2. General Relativity. Einstein at first simplified relativity by ignoring gravity. Once he put gravity back into the model, he described gravity as acting very similar to curved space (and time). Imagine a sheet held at the edges by lots of clamps. You place a weight on the sheet, and so the sheet bends downward, stretching the sheet. If you rolled a ping pong ball across the sheet before the weight was there, it would follow a straight line across. With the weight bending the sheet, however, the ball would curve, depending on its exact path. Imagine the ball travelling very near to the weight, but not through it. It would curve around the circular curvature, and perhaps would come out of that curvature at a different angle from that where it started.

Now consider the ball going closer to the weight. In this case, it might not be able to escape the curvature and get away. This is similar to falling (or landing) onto a planet. A rocket on a planet must also have enough velocity to get out of that curvature, much like a ball would need a pretty decent speed to get away from the weight. In 3D space, there is an extra dimension, but the principle is the same. Einstein did not say that spacetime was curved, just that gravity behaved as though it was.

3. Photons. Previously, most physicists has noticed that light behaves like waves. If light passes through a small hole, for example, it spreads out after passing through it, much like waves of water might through a hole in a dam. Einstein noted that light also acted like a particle, which eventually was called a photon.

4. Photo-electric effect. Einstein discovered that when sufficiently high energy (e.g. light, x-rays) hits a substance, the substance emits electrons. This is sort of like the beginning of solar power technology.

Answer 3

One of Einstein's most important contributions was his discovery of the relationship between mass and energy. Until that point, the world viewed these two things as completely different things. The fact that Einstein proved that they were related, and furthermore different forms of the same thing was a huge shock to the scientific community. This, of course, is all explained with what has to be the world's most famous equation: e=mc2.

Answer 4

Albert Einstein is most known for his groundbreaking scientific theories rather than inventions. Some of his most famous contributions include the theory of relativity, the formula E=mc^2, and his work on the photoelectric effect, which helped lay the foundation for modern physics.

Answer 5

formula leading to production of atomic bomb

Answer 6

Albert einstain was an inventor who never pass any of his exames and he invented not much just the speed of light
