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.

Einstein used the mathematics of probability and statistics to develop a formula for the Brownian Motion which could then be used to accurately predict the motion of the particles. This formula was made up of several equations which described the motion and accounted for different factors such as the size of the collision particles and the temperature of the environment.

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. In , he 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 in , Einstein 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 wrote that if he had not been a scientist, he would have been a musician. Einstein played the violin to a high standard.

I live my daydreams in music. I see my life in terms of music… I get most joy in life out of music. Einstein died in , at his request his brain and vital organs were removed for scientific study.

Famous pacifists — People who refused to fight and people who supported different forms of pacifism. Einstein's theories concerning relativity have so far held up spectacularly as a predictive models. Astronomers have found that, as the legendary physicist anticipated, the light of distant objects is lensed by massive, closer entities, a phenomenon known as gravitational lensing, which has helped our understanding of the universe's evolution.

In , the Advanced Laser Interferometer Gravitational-Wave Observatory also announced the first-ever direct detection of gravitational waves , created when massive neutron stars and black holes merge and generate ripples in the fabric of space-time. Further research published in found that the entire universe may be rippling with a faint "gravitational wave background," emitted by ancient, colliding black holes.

Adam Mann. Social Links Navigation. Feliciano auditioned and became a vocalist for the Joe Cuba Sextet. He was the rare baritone among salsa singers, and his deep voice and quick wit as an improviser made him a favorite among the Latino public. On October 5, , Feliciano made his professional singing debut with the Joe Cuba Sextet, singing the song "Perfidia".

He remained with the sextet for 10 years. In , he joined the Eddie Palmieri Orchestra and sang for them for two years. However, at the same time he began using drugs at 21 years old. Feliciano credits Tite Curet Alonso , the author of most of his hits and his best friend, with pushing him through his rehabilitation. As a result, he was a vehement anti-drug spokesperson, who volunteered to assist in the rehabilitation of fellow salsa artists who fell prey to drug addiction.

In , Feliciano came back to music with the album Cheo , his first solo recording. The album, which featured compositions by Feliciano's friend Tite Curet, broke all sales records in the Latino music market. The album included:. During the s, Feliciano recorded fifteen albums for Fania Record Co. He also recorded one of his first albums bolero music titled La Voz Sensual de Cheo.

The album was recorded in Argentina, with a band directed by Jorge Calandrelli. Feliciano also participated in the first salsa opera Hommy. In , Feliciano started his own recording company called "Coche Records". The next year, he became the first tropical singer to perform at the Amira de la Rosa Theater in Barranquilla , Colombia.

In , he landed the role of Roberto Clemente 's father in the musical Clemente. He also sang in the Universal Exposition in Seville. In , Feliciano recorded another album of bolero music, titled Los Feelings de Cheo. In Venezuela, he had a reunion with Eddie Palmieri. The album was listed among the 20 outstanding recordings of the year by the National Foundation of the Popular Culture of Puerto Rico.

In , he recorded Cheo en la Intimidad. In , Feliciano and Ruben Blades released a collaboration album titled Eba Say Aja where both artists performed each other's previously recorded songs. In the same year, Feliciano became part of Sergio George 's group called Salsa Giants whom he was touring with at the time of his death. They married on October 5, and had four children together.
