Quotes About Electromagnetism

Way back in 1831, Michael Faraday, one of the founders of our modern understanding of electromagnetism, was asked by an inquiring politician about the usefulness of this newfangled "electricity" stuff. His apocryphal reply: "I know not, but I wager that one day your government will tax it".

The electromagnetic attraction between negatively charged electrons and positively charged protons in the nucleus causes the electrons to orbit the nucleus of the atom, just as gravitational attraction causes the earth to orbit the sun.

declared Tesla as the true "father of radio.

Laplace's Demon, the hypothetical imp that knows the instantaneous positions and velocities of every particle in the universe, was said to be able to calculate the entire future or past by plugging these values into the equations that express the laws of mechanics and electromagnetism.

We should not be surprised that what people take away from science education is a syncretic mishmash, where gravity and electromagnetism coexist with psi, qi, karma, and crystal healing.

But the gravitational attraction between two smaller things, like two electrons, is a million billion billion billion billion times weaker than their electromagnetic repulsion.

The remarkable Scottish physicist James Clerk Maxwell worked out in the early 1860s that light was an interaction between electricity and magnetism. And this meant that in principle, you could have an electric wave creating a magnetic wave, creating an electric wave and so on, hauling itself through empty space by its own bootstraps without any material medium required – it is the electromagnetic field that acts as the material.

Einstein comes along and says, space and time can warp and curve, that's what gravity is. Now string theory comes along and says, yes, gravity, quantum mechanics, electromagnetism — all together in one package, but only if the universe has more dimensions than the ones that we see.

Electromagnetic theory and experiment gave us the telephone, radio, TV, computers, and made the internal combustion engine practical - thus, the car and airplane, leading inevitably to the rocket and outer-space exploration.

Max Planck s?cak bir kutu içinde denge durumunda bulunan elektrik alan?n? hesaplar. Bunun için küçük bir hileye ba?vurur: Alan?n enerjisinin "kuantumlar" yani enerji paketçikleri, topaklar? biçiminde da??ld???n? varsayar.

They meant to bring back together, as a unified subject, the discipline that had been subdivided for undergraduates into mechanics, electromagnetism, thermodynamics, hydrodynamics, and optics.

In 1914, a Finnish physicist named Gunnar Nordstrom found that all you had to do to unify gravity with electromagnetism was increase the dimensions of space by one. He wrote the equations that describe electromagnetism in a world with four dimensions of space (and one of time), and out popped gravity. Just by the extra dimension of space, you got a unification of gravity with electromagnetism that was also perfectly consistent with Einstein's special theory of relativity.

Love, that most banal of things, that most clichéd of religious motivations, had more power—Sol now knew—than did strong nuclear force or weak nuclear force or electromagnetism or gravity. Love was these other forces, Sol realized. The Void Which Binds, the subquantum impossibility that carried information from photon to photon, was nothing more or less than love.

James Clark Maxwell

The fine structure constant is undoubtedly the most fundamental pure (dimensionless) number in all of physics. It relates the basic constants of electromagnetism (the charge of the electron), relativity (the speed of light), and quantum mechanics (Planck's constant).

Calculate the fine structure constant from first principles.

The physical brain continues to be probed, and electromagnetism continues to be thought of as the carrier of ESP "signals," while all along, new wave research in physics has virtually established the fact that there is a second reality that operates totally independently of any brain-electromagnetic arrangement. In fact, the old reality pales in importance if the basic elements of the new second reality are grasped.

The relationships (Maxwell's equations) are the epitome of mathematical consieness, compact enough to fit on a T-shirt yet powerful enough to describe all manner of electromagnetism.
