Seldom has a scientist received such public attention for Leaving the ability for learning that he had. in 1905, Einstein examined the phenomenon discovered by Max Planck, according to which electromagnetic energy seemed to be emitted from radiating objects in quantities that were ultimately discrete.
The energy of these emitted quantities—the so-called light-quanta—was directly proportional to the frequency of the radiation. This circumstance was perplexing because classical electromagnetic theory, based on Maxwell’s equations and the laws of thermodynamics, had assumed that electromagnetic energy consisted of waves propagating in a. hypothetical, an all-pervasive medium called the luminiferous ether and that the waves could contain any amount of energy no matter how small. Einstein used Planck’s quantum hypothesis to describe visible electromagnetic radiation or light. According to Einstein’s heuristic viewpoint, light could be imagined to consist of discrete bundles of radiation. Einstein used this interpretation to explain the photoelectric effect, by which certain metals emit electrons when illuminated by light with a given frequency. Einstein’s theory, and his subsequent elaboration of it, formed the basis for much of quantum mechanics.
Another of Einstein’s theories concerned statistical mechanics, a field of study that had been elaborated by, among others, Ludwig Boltzmann and Josiah Willard Gibbs. Unaware of Gibbs’ contributions, Einstein extended Boltzmann’s worked calculated the average trajectory of a microscopic particle buffeted by random collisions with molecules in a fluid or in a gas. Einstein observed that his calculations could account for Brownian motion, the apparently erratic movement of pollen in fluids, which had been noted by the British botanist Robert Brown.
Answer:
Albert Einstein was born in Germany into a Jewish family on 14th March 1879. Furthermore, Einstein had to deal with speech difficulties early on but was a brilliant student at his elementary school. His father, Hermann Einstein founded an electrical equipment manufacturing company with the help of his brother.
At the age of five, Albert’s father showed him a pocket compass. Moreover, this made him realize that the needle was moving due to something in empty space. According to Einstein, this experience left a deep and lasting impression on him.
In 1889, a ten-year-old Albert became introduced to popular science and philosophy texts. This happened due to a family friend named Max Talmud.
Albert Einstein spent time on books like Kant’s ‘Critique of Pure Reason’ and ‘Euclid’s Elements’. From the latter book, Albert developed an understanding of deductive reasoning. Furthermore, by the age of 12, he was able to learn Euclidian geometry from a school booklet.
Einstein’s father’s intention was to see his son pursue electrical engineering. However, a clash took place between Albert and the authorities. This was because Albert had resentment for rote learning as, according to him, it was against creative thought.
Achievements of Albert Einstein
In 1894, Einstein’s father’s business failed and his family went to Italy. At this time, Einstein was only fifteen. During this time, he wrote ‘The Investigation of the State of Aether in Magnetic Fields’, which was his first scientific work.
In 1901, there was the publishing of a paper by Einstein on the capillary forces of a straw in the prestigious ‘Annalen der Physik’. Furthermore, his graduation took place from ETH with a diploma in teaching.
In the year 1905, while working in the patent office, there took place the publishing of four papers by Einstein in the prestigious journal ‘Annalen der Physik’. Experts recognize all four papers as tremendous achievements of Albert Einstein. Therefore, people call the year 1905 as Einstein’s wonderful year’.
The four papers were special relativity, photoelectric effect, Brownian motion, and equivalence of matter and energy. He also made the discovery of the famous equation, E = mc².
The theory of relativity was completed by Einstein in 1915. The confirmation of his theory was by British astronomer, Sir Arthur Eddington, during the solar eclipse of 1919.
There was the continuation of research works by Einstein and finally, in 1921, his efforts bore fruits. Most noteworthy, the Nobel Prize in Physics was awarded to Albert Einstein for his services to Theoretical Physics.
