All modern people are the conglomeration of so many ethnic mixtures that no pure race remains. Once in the US, Einstein dedicated himself to a strict discipline of academic study. He would spend no time on maintaining his dress and image. Einstein was notoriously absent-minded. In his youth, he once left his suitcase at a friends house. Although a bit of a loner, and happy in his own company, he had a good sense of humour.

On January 3,Einstein received a letter from a girl who was having difficulties with mathematics in her studies. Einstein consoled her when he wrote in reply to her letter. I can assure you that mine are still greater. But, he followed no established religion. His view of God sought to establish a harmony between science and religion. Einstein described himself as a Zionist Socialist.

He did support the state of Israel but became concerned about the narrow nationalism of the new state. Inhe was offered the position as President of Israel, but he declined saying he had:. Albert Einstein was involved in many civil rights movements such as the American campaign to end lynching. But he also spoke highly of the meritocracy in American society and the value of being able to speak freely.

On the outbreak of war inEinstein wrote to President Roosevelt about the prospect of Germany developing an atomic bomb. He warned Roosevelt that the Germans were working on a bomb with a devastating potential. Roosevelt headed his advice and started the Manhattan project to develop the US atom bomb. But, after the war ended, Einstein reverted to his pacifist views.

Einstein said after the war. In the post-war McCarthyite era, Einstein was scrutinised closely for potential Communist links. He was also a strong critic of the arms race. Einstein remarked:. Einstein was feted as a scientist, but he was a polymath with interests in many fields. In particular, he loved music. He established that lead was the final decay product of uranium, noted that the lead-uranium ratio was greater in older rocks and, acting on a suggestion by Ernest Rutherford, was the first to measure the age of rocks by the decay of uranium to lead, in He got results of ages of to million years, the first success of radiometric dating.

More recently, older mineral deposits have been dated to about 4. We're doing our best to make sure our content is useful, accurate and safe.

However, during his life, Einstein participated in brain studies, and at least one biography claimed he hoped researchers would study his brain after he died.

In keeping with his wishes, the rest of his body was cremated and the ashes scattered in a secret location. According to The New York Timesthe researchers believe it might help explain why Einstein was so intelligent. Rorke-Adams said she received the brain slides from Harvey. Einstein has also been portrayed on screen. Walter Matthau portrayed Einstein in the fictional comedy I.

A much more historically accurate depiction of Einstein came inwhen he was the subject of the first season of Geniusa part scripted miniseries by National Geographic. Johnny Flynn played a younger version of the scientist, while Geoffrey Rush portrayed Einstein in his later years after he had fled Germany. Ron Howard was the director.

At its core, the Photoelectric Effect occurs when a photon of light strikes a metal surface and energy is transferred from the photon to the electrons of the metal. This is known as the absorbance of the photon. With enough energy, the electrons can become excited and leave the surface, transferring their energy to the outside environment.

This is known as the emission of electrons. What sets the Photoelectric Effect apart from other phenomena is that the amount of energy required to cause the effect is fixed. This means that the minimum required energy of the photon must be above a certain threshold in order to cause the effect. This threshold energy is called the work function and is dependent on the material of the surface.

The Photoelectric Effect has a number of real-world applications. One of the most well-known is the photodiode, which is a device that detects light and converts it into electricity. These are used in devices such as cameras and photocopiers. Additionally, solar cells rely on the Photoelectric Effect to convert sunlight into direct current DC electricity.

This is used to power everything from homes to electric cars. It states that matter and energy are related, and can be converted from one to another. This equation has been used to explain many phenomena in the cosmos, including how stars create energy through nuclear fusion and how black holes convert matter into energy. In other words, mass can be converted into energy and energy can be converted into mass.

This equation is often used to describe the process of nuclear fission, where atoms split into smaller particles, releasing energy in the process.

It is also used to explain how nuclear fusion occurs, when atoms combine to produce heavier elements, resulting in the release of large amounts of energy. In these events, enormous amounts of energy are released when two stars collide, which is explained by this equation. In addition, the formation of black holes is also attributed to the mass-energy equivalence.

As matter is pulled into a black hole, it is converted into intense gravitational energy. Albert Einstein is one of the most celebrated scientists of all time, and his work on the Brownian Motion is one of his lesser known but still impressive studies. This study was a mathematical investigation into the random motion of particles suspended in a fluid.

First, that the average speed of these particles stayed constant regardless of the temperature of the environment. Second, that the average displacement of the particles increased with increasing temperature. From this, he concluded that the motion must be due to the bombardment of the particles by individual molecules, each exerting a tiny amount of force on the particle.
