Electromagnetic Waves Quotes

Others are engaging even in an eco-type of terrorism whereby they can alter the climate, set off earthquakes, volcanoes remotely through the use of electromagnetic waves. So there are plenty of ingenious minds out there that are at work finding ways in which they can wreak terror upon other nations. It's real, and that's the reason why we have to intensify our efforts, and that's why this is so important.

Others [terrorists] are engaging even in an eco-type of terrorism whereby they can alter the climate, set off earthquakes, volcanoes remotely through the use of electromagnetic waves

Our television transmitters leak out from the Earth. And actually, there's a sphere surrounding the Earth from the earliest television signals, maybe 70 years ago, that's going out one light year per year. But it's really weak.

This change in the conception of reality is the most profound and the most fruitful that physics has experienced since the time of Newton. Refering to James Clerk Maxwell's contributions to physics.

What is history? Its beginning is that of the centuries of systematic work devoted to the solution of the enigma of death, so that death itself may eventually be overcome. That is why people write symphonies, and why they discover mathematical infinity and electromagnetic waves.

[X-ray's] accidental discovery in the late 1800s fits seamlessly into modernity's fascination with, and belief in, the power of technological transparency: the desire to domesticate time (cinema), to preserve and capture the surface of the fleeting (photography), to see inside (x-ray).

We can scarcely avoid the inference that light consists in the transverse undulations of the same medium which is the cause of electric and magnetic phenomena.

Now what is history? It is the centuries of systematic explorations of the riddle of death, with a view to overcoming death. That's why people discover mathematical infinity and electromagnetic waves, that's why they write symphonies.

Now, since the time of Newton there had been a debate about whether light was a wave - that is, a traveling disturbance in some background medium - or a particle, which travels regardless of the presence of a background medium. The observation of Maxwell that electromagnetic waves must exist and that their speed was identical to that of light ended the debate: light was an electromagnetic wave.

If it is love that makes the world go round, it is self-induction that makes electromagnetic waves go round the world.

Maxwell's Equations have had a greater impact on human history than any ten presidents.

It required unusual inquisitiveness to pursue the development of scientific curiosities such as charged pith balls, the voltaic cell, and the electrostatic machine. Without such endeavors and the evolution of associated instrumentation, initially of purely scientific interest, most of the investigations that lead to the basic equations of electromagnetism would have been missed. ... We would have been deprived of electromagnetic machinery as well as knowledge of electromagnetic waves.

For under certain conditions the chemical atoms emit light waves of a specific length or oscillation frequency - their familiar characteristic spectra - and these can come in the form of electromagnetic waves only from accelerated electric quanta.

We may produce at will, from a sending station. an electrical effect in any particular region of the globe; we may determine the relative position or course of a moving object, such as a vessel at sea, the distance traversed by the same, or its speed.

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.

From a long view of the history of mankind — seen from, say, ten thousand years from now, there can be little doubt that the most significant event of the 19th century will be judged as Maxwell's discovery of the laws of electrodynamics. The American Civil War will pale into provincial insignificance in comparison with this important scientific event of the same decade.

My decision to begin research in radio astronomy was influenced both by my wartime experience with electronics and antennas and by one of my teachers, Jack Ratcliffe, who had given an excellent course on electromagnetic theory during my final undergraduate year.

Radiative transfer calculations I can do standing on my head.

Amplifying atoms is more subtle than amplifying electromagnetic waves because atoms can only change their quantum state and cannot be created. Therefore, even if one could amplify gold atoms, one would not realize the dreams of medieval alchemy.

Nicola Tesla didn't say, 'I have to make wireless electricity!' The brain does not work that way.

Since my own genome was sequenced, my software has been broadcast into space in the form of electromagnetic waves, carrying my genetic information far beyond Earth. Whether there is any creature out there capable of making sense of the instructions in my genome, well, that's another question.

Nobody ever told us all matter radiated. We just assumed it did.

At the head of these new discoveries and insights comes the establishment of the facts that electricity is composed of discrete particles of equal size, or quanta, and that light is an electromagnetic wave motion.

. . . hummings and clickings could be heard-the sounds attendant to the flow of electrons, now augmenting one maze of electromagnetic crises to a condition that was translatable from electrical qualities and quantities to a high grade of truth.

I happen to have discovered a direct relation between magnetism and light, also electricity and light, and the field it opens is so large and I think rich.
