Albert Einstein.\n1. In 29 march 1919 was a total eclipse of the Sun. The Royal Astronomical Society sent two expeditions one in Brazil and the other in Guinea to check the German scientist Albert Einstein theory, that the light of the stars is deviated by the Sun gravitational field. The results show a deviation of 1,75 seconds of arc, when Albert Einstein calculated a deviation of 1,70 seconds of arc. After 33 years in 1952 when they used a better equipment the results matched Albert Einstein`s calculation.\n2. Albert Einstein convinced the President of the United States  F.D.Rooswelt, about the emergency  of developing the A-bomb because the German scientist had the means and the material to make one before the Americans.

Of all time. There is so much choice, but here are 5 and why:\n\n1. Isaac Newton - introduced mathematical formalism to physics and created calculus (he called it fluxions)\n2. James Clerk Maxwell -  gave the first unified explanation of electromagnetism\n3. Ludwig Boltzmann - gave the first mathematical interpretation of the profoundly important second law of thermodynamics, and derived the Botlzmann distribution for gases\n4. Max Planck - founded quantum mechanics\n5. Richard Feynman - developed the first way to handle the fiendish equations of sub nuclear particle physics,  and thereby made quark theory possible\n\nOf the 5 I would pick Feynman as my number 1 - no other physicist has had such profound intuition as to how the universe works. You can still buy his popular science books.

Michaelson and Morely did some experiments to try to see if the speed of light incipient on the earth was different for light coming from different directions.  Th idea was that if light travels in waves (as it seems to in many regards), then these waves needed to travel through a medium (like when sound waves travel through the air).  This medium was termed "the ethereal ether" and was thought to pervade space, including places with a vacuum; light was thought to be a wave travelling through it.  So Michaelson and Morely decided to try to see our speed relative to the ether by using somthing called an interfereometer.  This compared the speed of lightcoming from different directions.  The idea was that a star we are headed towards should reveal a higher speed of light, while ones we're rushing away from should have a lower speed, due to the Doppler effect.  What they found was that the speed was the same in all directions, meaning that if there was an ether, then we we perfectly at rest relative to the ether.\n\nThen mathematicians and physicists looked at the theories of Scottish physicist James Clerk Maxwell.  Maxwell had taken all existing theories on electricity and megnetism and unified them into a single, cohesive set of equations.  These equations showed how electricity could create a magnetic field, and a magnetic field could induce an electric current.  This could happen in such a manner that an electric field would induce a magentic field, which in turn induced an electric field, which in turn induced a magnetic field, and so on.  The equations made it clear that this wave would travel at a certain specific speed.  Incidentally, that speed was similar to the speed of light measured by French scientist Fizeau in 1849 (several decades earlier) and confirmed by Foucault.\n\nIt was all of this that led Einstein to formulate his special theory of relativity.  Since light moved as an electromagnetic wave, and since those waves had a speed that was predicted directly by Maxwells equations and was independent of the velocity of the observer, Einstein came to recognize that simultaneity was not a universal concept, and that time changed with velocity.  The idea of the ether was discarded as needless baggage.

FARADAYS LAW of ELECTROMAGNETIC INDUCTION\nElectromagnetic Induction, in electricity, the name given to the production of an electromotive force (emf) across the ends of a conductor, such as a wire, when it experiences a changing magnetic field (see Magnetism). This effect was discovered independently by the British physicist Michael Faraday and the American physicist Joseph Henry.

Maxwell's equations (sometimes called the Maxwell equations) are the set of four equations, attributed to James Clerk Maxwell, that describe the behavior of both the electric and magnetic fields, as well as their interactions with matter.\n\nMaxwell's four equations express, respectively, how electric charges produce electric fields (Gauss' law), the experimental absence of magnetic monopoles, how currents and changing electric fields produce magnetic fields (the Ampere-Maxwell law), and how changing magnetic fields produce electric fields (Faraday's law of induction).\nfor the theory of thid equation click on the link below:\nhttp://en.wikipedia.org/wiki/Maxwell%27s_Equations\ni hope it will help you.....

overall i'd say e=mc2-einstein of course. his theory is 100 years+ old & has yet tobe proven because science hasn't caught up yet in the modern era & the internet & computers & science universally. immediately the profound effects of what thomas edison has done by far contributed the most. have you ever lost power for more than two days. i never have until last year. let me tell you it was rather bleak. water got bad. food got bad. no fresh air & no a/c.thomas edison is #1. not to say the alexander graham bells, the polio vaccine, the x-ray inventor who died from the process of discovery, & much more have all been significant factors to our well being and yes the nuclear people are included for better & for worse.

the theory that light, and all electromagnetic radiation (radio waves, x-rays, microwaves) travels as a wave, like the ripples on a plucked string. these waves look like sine and cosine graphs.\n\n\nthis was proved to be an incomplete picture by eistein's analysis of the photoelectric effect, for which he won the nobel prize. this showed light was in fact made of particles called photons. however, quantum wave theory now tells us that all matter is both a particle and aa wave; the matter is contained in a particle, but the location of the particle is determined by a wave.

Hmmm.  Reading “Tulips” by Padraic Colum?  Anyway…\n\nBoth are optical instruments of the late 17th Century.  Newton used a prism to break sunlight up into its contituent colors—red, orange, yellow, green, blue, purple, and infinitely fine gradations in between.  Spinoza, although nowadays more famous for his philosophy, actually made a living grinding lenses for telescopes and such.  Both tools bend and distort light, and both have (relatively) simple mathematical descriptions.\n\nIf indeed, the aforementioned poem is what called to mind the question, I think the reference has to do with the abstract mathematics of prisms and lenses translating into real-world manipulation of light.\n\n\nRyan Wyatt\nRose Center for Earth & Space\nNew York, New York

Nope, everyone has it wrong.  There is a secret and even though we know it, we still cannot find the answer.  The questions is, "What is light."  Nobody knows what light is.  There are many theories, but none can be verified.  If we knew the answer to this question, there would be literally no limit to what could be known and done.  At one time we had no idea what electricity was, but, once we found out it's priciples and properties, look what was done with appliances and computers.  No, apply similar advances if we knew the principles of light.  A trip to Alpha Centauri (the closest star) would take shorter time to reach than Mars does now.

Michael Farady of England created electricity through magnets. And people before him knew about electricity for long time, so its difficult to answer who invented it.

I know Einstein came up with it and it deals with energy.\n\nEnergy(E) = Mass(m) * Speed of Light(c2)

Light is both a wave and a particle at the same time.\n\nLight is a form of energy, and depending on how you observe it, it exibits both properties of an electromagnetic wave or a particle (photon).\n\nElectromagnetic waves do not require a medium in which to propigate, they are a self propigating electric and magnetic field, allowing it to travel through a vacuum.\nEvidence of this can been seen in diffraction patterns, such as when you look at the rainbow effect on a CD.\n\nPhotons are a "quantized" amount of light.  These light partciles are absorbed or given off by atoms in something called the "photoelectric effect" (which Einstien received a nobel prize for).\nEvidence for this can be seen in things like LEDs or when you study the structure of the atom.

OK, here they are verbally:\n\n"Maxwell's four equations express, respectively, how electric charges produce electric fields (Gauss' law), the experimental absence of magnetic monopoles, how currents and changing electric fields produce magnetic fields (the Ampere-Maxwell law), and how changing magnetic fields produce electric fields (Faraday's law of induction)." [See source.]\n\nGauss' Law--simply says electrons in motion will create a force field around the current.  This law follows the inverse square of the distance rule and the phenomenon is the basis for radio and TV broadcasting waves.\n\nThe monopole equation simply says that there must be both a north and south pole in magnetism.  (However, sometimes fictitious monopoles are used mathematically to solve some problems.)\n\nThe Ampere-Maxwell equation links changing electrical current to the creation of magnetic flux.  The Faraday equation links changing magnetic flux to the creation of electrical current.  This is the stuff that electric motors and electric generators are made of.\n\nThe Maxwell equations have a lot of practical applications.  Wave guides, such as for high powered radars, and coax cables, like for your TV, are designed using Maxwall equations.

The events leading to the crisis in science from which Quantum Mechanics was born begain in 1859.\n\nIn 1859 Gustav Kirchhoff came up with the theorem about "black body" radiation, that is for something the absorbs all light that hits it. This will heat the material - no matter what it is - and will emit a specific energy distribution. However, Kirchhoff didn't know what the distribution was.\n\nWhat was quickly found that the distribution could be derived from only one side of the spectrum. If you derived the blue end, then the red end went to infinifty. If you derived the blue end, the the red went to infinity.\n\nFinally in 1900 Max Planck solved the problem by making an assumption - light can only have discrete values. That was strange since it had been assumed that light could have any frequency. But in the context of the blackbody problem a series of tiny steps in energy were needed to determine a correct solution to the black body problem.\n\nThen in 1905 Einstein was looking at something called the photoelectric effect which was also puzzling people. He solved the problem by using Planck's idea of quantized energy.\n\nThen in 1913 Neils Bohr came up with a way to understand the spectrum from a hydrogen atom by postulatins a quantization.\n\nSo by this point it was all taking off, soon to be added to be Shrodinger, Dirac, and Heisenberg into the comptete base of modern Quantum Mechanics.
