Einstein why is the sky blue




















In he began his school career in Munich. He studied mathematics, in particular calculus, beginning around In Albert failed an examination that would have allowed him to study for a diploma as an electrical engineer at the Eidgenossiche Technische Hochschule in Zurich.

Instead he got a clerical job in the patent office at Bern, Switzerland. It was not what he wanted but it would give him leisure for studying and thinking. While over there he wrote scientific papers.

Einstein submitted one of his scientific papers to the University of Zurich to obtain a Ph. In he sent a second paper to the University of Bern and became lecturer there. This job gave him much time for scientific research. Albert Einstein was born on March 14th, , in Wurttemburg, Germany.

He frequently moved from town to town with his family throughout his young life, and always showed an interest in science. As an adult he attended Swiss Federal Polytechnic School and earned his degree as a teacher of physics and mathematics.

This theory would later contribute to other ideas and discoveries, one of which would be the Mass-Energy Equivalence. The biggest direct effect on literature was that relativity made time travel possible.

Before Einstein was thought to be a fantastic yet impossible feat. Relativity only solved half the problem, time travel into the future. This occurs through time dilation.

The science fiction pulps picked up on this idea and went wild. Einstein was educated at the Federal Polytechnic School in Zurich where he learned to teach physics and mathematics. After graduation in , he could not find a job so he decided to take a respectful job at the Swiss Patent Office. While working there, he returned to school to pursue his Doctorate degree which he completed in After working in the Patent Office, as Privatdozent and Professor Extraordinaire in Zurich, Professor of Theoretical Physics at Prague, Professor at the University of Berlin created the theory of relativity and gravitation and Doctor of the Kaiser Wilhelm Physical Institute, in he became a German citizen and remained there until For political reasons the Nazi Control and all that it would bring that year, he renounced his citizenship and moved to America to take the job as Professor of Theoretical Physics at Princeton.

Proper use of particle accelerators, as well as the analysing of high-speed collisions within them, this wouldn't be possible without a thorough comprehension of mass-energy equivalence, which is what Einstein discovered with his theory of specia He put together the concept of mass and the concept of energy and showed that they are actually the same thing when you think about them correctly.

Or, alternatively, given an amount of energy, you can determine how much mass you can create from it. Aristotle is the first, so far as we know, to ask the question about why the sky is blue, in the treatise On Colors ; his answer is that the air close at hand is clear and the deep air of the sky is blue the same way a thin layer of water is clear but a deep well of water looks black.

This idea was still being echoed in the 13th century by Roger Bacon. Kepler too reinvented a similar explanation, arguing that the air merely looks colorless because the tint of its color is so faint when in a thin layer. But none of them offered an explanation for the blueness of the atmosphere. So the question actually has two, related parts: why the sky has any color, and why it has a blue color. In the Codex Leicester , Leonardo da Vinci, writing after , noted, "I say that the blue which is seen in the atmosphere is not its own color, but is caused by the heated moisture having evaporated into the most minute, imperceptible particle, which beams of the solar rays attract and cause to seem luminous against the deep, intense darkness of the region of fire that forms a covering above them.

Isaac Newton contributed, both by asking why the sky was blue, and also by demonstrating, through his pathbreaking experiments with refraction, that white light could be decomposed into its constituent colors. Many now-forgotten and many still-remembered scientists since Newton joined in. What might refract more blue light towards our eyes? In , the mathematician Leonhard Euler speculated on the wave theory of light helping to explain why the sky is blue.

The 19th century saw a flurry of experiments and observations of all sorts, from expeditions to mountaintops for observation to elaborate efforts to recreate the blue sky in a bottle—as chronicled in Peter Pesic's wonderful book, Sky in a Bottle.

Countless careful observations of blueness in different locations, different altitudes, different times, were made, including with bespoke devices known as cyanometers. Horace-Benedict de Saussure invented the first cyanometer in His version had 53 sections with varying shades of blue arranged in a circle. As a gas becomes colder and colder, quantum mechanics tells us that the wavelike behavior of the atoms becomes more and more important. At the lowest temperatures, within a few hundred billionths of absolute zero In this state, it hardly even makes sense to talk about individual atoms because they all behave as one collective object.

In recent developments, BECs are being used to create atom lasers, the equivalent of a laser made of light; in the study of superconductivity the ability of some materials to conduct electrical current without any resistance ; superfluidity the ability of some materials to flow without resistance and in refining measurements of time and distance.

The Einstein refrigerator is an absorption refrigerator which has no moving parts and requires only a heat source to operate - it does not require electricity to operate, needing only a heat source, e.

Patent 1,, Although Einstein did not invent the bomb and did not participate in the Manhattan Project, his theories laid the foundation for it. In Einstein collaborated with several other physicists in writing a letter to President Franklin D. Roosevelt, pointing out the possibility of making an atomic bomb and the likelihood that the German government was embarking on such a course. The letter, which bore only Einstein's signature, helped lend urgency to efforts in the U. Why is the sky blue?

Albert Einstein Was Born in In the botanist Robert Brown observed under the microscope the movement or motion of plant spores floating in water and moving about randomly all the time. It was known that when light was shone on certain substances, the substances gave out electrons, but that only the number of electrons emitted, and not their energy, was increased when the strength of the light was increased.

This theory provides a consistent explanation for the way radiation light, for example and matter interact when viewed from different inertial frames of reference, that is, an interaction viewed simultaneously by an observer at rest and an observer moving at uniform speed.

Think Like Einstein.
