Albert Einstien grew up in a secular jewish family .His father ,Hermann Einstein ,was a salesman and engineer who with his brother ,founded electrotechnische Fabric j. Einstien &Cie munich based company that manufactured electrical equipment . Albert’s mother ,the former pauline koch ,ran the family households.Einstein had one sister ,Maja,born two
years after him.
His work: Near the begging of his career ,Einstein thought that “Newtonian Mechanics” was no longer enough to reconcile the laws of classical mechanics with the laws of “electromagnetic field” , this led him to develop his famous “Special theory if relativity”.
What is the theory of Relativity: Special theory of Relativity(S.T.R.) describe the relationship b/w space and time.
It is based on two postulates
1). The laws of physics are invariant (identical)in all inertial system(non accelerating frame of reference )
2). The speed of light in a vacuum is the same for all observers ,regardless of the motion of the light source.
The SRT explains how space and time are linked for objects that are moving at a consistent speed in a straight line .One of its most famous aspects concern objects moving at the speed of light .
For understanding SRT ,simply take an object approaches the speed of light ,its mass becomes infinite and it is unable to to go any faster than light travels , unless its mass must be infinite.
So this theory simply tells that no one ting and no body can cross the limit of speed of light he can achieve 0.9x of light speed but not absolutely speed of light.
By (SRT) we can predict that time travelling even could be possible in near future.
But he was not worked only (S R T) but also many theories and principals were discovered by him here are some other famous works.
Einstein Refrigerator With Hungariun -born physicist Leo Szilard ,Einstein developed a novel refrigerator scheme that involved no motors ,moving parts or coolant. The idea exploits that the water boils at lower temperature at lower pressure .Einstein and Szilard had the idea to place a flask of butane on a flame and under a vapor of amonia .
Because the amonia had a lower pressure it lowered the boiling point of the butane, and as the butane boiled off it sucked the energy from its surroundings,cooling an adjacent compartment .
Gravitational lensing: Mandi ,who had studied Einsteins theory of general relativity ,believed that if an object in space was big enough ,it could bend light around it all on sides creating a kind of”Gravitational Lens “ that would focus on the light that appear on earth.
Bose –Einstein condensate: Einstein realized that if particles are cooled down to just a hair’s breadth above absolute zero (-459.67 degree Fahrenheit)they will all fall back to the same lowest energy state and will be indistinguishable .
That in essence would mean that a collection of particles would act as if it were just big one particle and would form entirely new state of matter .This bizzare “superblob of matter” ,now known as Bose-Einstein condensate has zero viscosity.
Grand –Unified theory: Perhaps Einstein’s most famous failure is that he never managed to crate a theory that would unite all fundamental forces (gravitational force,electromagnetism ,weak interaction ,strong interaction).
He spent all his later years plugging away at the so called “Grand unified theory “ and died without cracking it.
Mass-Energy relationship: Albert Einstein’s world Famous equation “E=MC2” .
This equation states that the amount of energy possessed by an abject is equal to its mass multiplied by the square of speed of light .
Since the speed of light is an incredibly high number almost 300000m/s ,a small amount of mass contains a lot amount of energy .This equation easily describe why atomic bombs are so powerful,once its mass is converted to an explosion.
This equation also shows that mass increases with speed ,which effectively puts a speed limit on how fast things can move in universe .Simply put the speed of light (c) is the fastest velocity at which an object can travel in vacuum .As an object moves ,its mass also increases .Near the speed of light ,the mass is so high that it reaches infinity,and would require infinite energy to move it ,thus capping how how fast an object move.
Another strange conclusion of Einstein’s work comes from the realization that time moves from the realization that time moves .An object in motion experience time dilation ,meaning that moves more slowly when one is moving ,than when one is standing still.Therefore ,a person age moving more slowly than a person at rest .So yes ,when astronaut Scott Kelly spent nearly a year aboard the :International Space Station” in 2015-2016his twin astronaut brother Mark Kelly aged a little faster than Scott.
So these are the most famous works of Albert Einstein ,that undoubtedly shows how much intelligent he was .
Some strange fact about Albert Einstein: 1). When albert’s mother ,gave birth to him ,she noticed that Einstein’s head was so big and misshapen that he was deformed!
2). As child ,Einstein seldom spoke .when he did spoke very slowly –indeed ,he tired out entire sentences his head until he got them right before he spoke aloud.
3). Einstein was a ladies’ Man, after Einstein divorced Mileva ,he soon married his cousin Elsa Lowenthal. Actually ,Einstein also considered marrying Elsa’ Daughter llse ,but she demurred
4). After his death in 1955, Einstein’s brain was removed without permission from his family by Thomas Stoltz Harvey the princeton Hospital pathologist who conducted the autopsy .Harvey took the brain home and kept it in jar .He was later fired from his job for refusing to relinquish the organ.
These are some unknown facts about albert Einstein.
