One of the most perplexing and frustrating biological enigmas which scientists have been trying to solve for years is how animals from European robins to fruit flies to beluga whales can navigate their way across earth in the proper direction with each change of season. Decades have passed with no concrete evidence of any biological compass evidence found within any of these incredible travelers; theories have only been postulated. Recently, however, some researchers claim they’ve uncovered a light sensitive protein that may contain certain electrons that interact in such a way that allows animals to find their way to their destination. Photons enter through the eye and deliver enough energy to hit the protein, called cryptochrome, and separates …show more content…
Transistors control a large current flowing through a semiconductor with the use of a small current. The creation of transistors was made possible by the Pauli exclusion principle, which states that each electron has a unique set of quantum numbers, and only two electrons can occupy the same orbital. Knowledge of the exclusion principle allowed developers like Shockley, Van Vleck, and Bardeen to create the transistor with semiconductors, which also rely heavily on quantum mechanics (they only allow a certain number of electrons through until a change occurs in the junctions of its positive and negative layers). , Originally developed for the amplification of radio signals, transistors can be found in thousands of different items today. Likely the most beneficial way to utilize transistors is in computers. Due to the nature of semiconductors, when voltage is applied to a transistor, a gate can be opened or closed; thus the electrons can flow freely through or be stopped from doing so. This high or low flow of electrons can be coded as a 0 or 1, and is the basis of the binary code that runs nearly all electronics today. Those scientists who studied quantum mechanics not only changed the world of physics, but they unknowingly created something that has shaped the world and the future. Computers are vital for today’s society, for everything from communication to research to making predictions to design. Binary …show more content…
An understanding of the study and fissionable systems ultimately led to a discovery that there is a tiny, yet exsistent probability that a fissionable system at its lowest excitation state can be broken into two fission fragments. This can be harnessed into chain reactions, which was accomplished by American scientists in 1945. Fission bombs, as they were called, are known today as atomic bombs. During World War II, America dropped two atomic bombs on the Japanese, killing more than 200,000 people. While it ultimately ended with the conclusion of the war, quantum mechanics contributed to one of the biggest mass killings in world
