over quite a few years actually. But all right, so now let's-- what you said is true. So Weinberg, Glashow, and Salam showed that electromagnetism and the weak force at high energies were the same. There was a problem, however, and the problem is that electromagnetism has an infinite range, And we know that because we can see stars that are millions of light-years
million degree temperatures. And temperature really is kinetic energy. It's motion, it's velocity. So that these particles are moving so fast that even though they're coming together and there's this repulsive electromagnetic force, they can still come close enough that another force comes into play, which is the strong force. And then once you get within a very close distance on the order of the scale of those nuclei themselves, of those atomic nuclei. So the tiniest thing you could
There's no obvious way to fit in Newton's gravity to relativity. Electromagnetism fit perfectly, but gravity was a stubborn resistor. So Einstein thought about that.
and we can get to that doubling number. "electromagnetic radiation"-- light, heat, radio waves.
And it does so by the exchange of a particle-- a photon-- the quantum of the electromagnetic field. Electromagnetic waves come in particles and photons of the individual Now, what Feynman used in developing this is a key aspect of quantum mechanics, which is central to quantum mechanics, which is really the same thing that's used in Washington
According to the standard model, all the fundamental particles are originally massless, like photons, the particle carrying electromagnetic force, also known as a particle of light, whose speed in space-time is the maximum allowed speed, the speed of light.
What I love about his research-- and this always blows me away --is that the heart-- what they've discovered --is the heart actually has-- generates the largest electromagnetic field in the whole human body. And it's waves-- the amplitude of these waves are 60 times greater than that of the brain.
around, uh, one of the lab technicians and a physicist. We're about to step into the so-called radio frequency room. That's a room that has been electromagnetically isolated from everything else and that's where the dark matter detector is placed and you can see that we are dressing up as if we're going into a clean room. In fact, it's worse than going into a clean room.
variety of means, physical means, those particles. You push them together. The most common is called laser inertial fusion. An electromagnet is a loop that has electrical current flowing in it that generates a magnetic field. And for a theta pinch,
force. Uh, there are four fundamental forces of the universe. There's the gravitational force which keeps us here, the electromagnetic force which lights up our our world, and the two nuclear forces. We want a theory that explains all four. You know, when people watch your interviews and they read your books, what do you think is the fundamental
You cannot see them, but they do exist, just like the electromagnetic spectrum. These electromagnetic waves are all around us. We cannot see them with the naked eye.
But we're in complete disharmony with EMFs. And electromagnetic fields is a terrible thing. It's discombobulating our energy field and creates dis ease in our body.
And that's the spooky action at a distance that he invented. For electromagnetism, the nuclear forces, particles that we know about, electrons and quarks and so forth, you start with a classical theory,
Also, one of very interesting characteristics of this electromagnetic spectrum we are focusing on is that plants are reflecting two parts of electromagnetic spectrum. One is green light, what we see in our eyes as green light. Another is infrared. Unfortunately, we can't see it, but we can sense it from space.
can you navigate free-flyers using just electricity-- Electromagnetic formation flight where you're trying to control the distance between two objects using big RINGS generating an electromagnetic field. And certainly one of the concepts they're looking at for wide aperture type telescopes, where you want to keep a lot of different things in synchronous operation in orbit without using fuel.
OK, again, what's this got to do with anything? the electromagnetic interactions responsible for all the interactions in the biology of your body-- the weak force is actually responsible for the processes
So we're going to build on that as well. So electromagnetic field three feet from you. The other thing with the human energy to touch on is that, I mentioned, you're a battery.
So electromagnetic magnetic were invented.
variety of means, physical means, those particles. You push them together. The most common is called laser inertial fusion. So in an electromagnet , there are a variety of ways to make a magnetic field. One of the most famous, I think everyone is familiar
And used an electromagnet to show he had powers strongest person in the village would go over and lift -- what's called the Light-Heavy chest.
We can do electromagnetic compatibility measurements here.
Then a second electromagnetic lens magnified this imprint down onto a fluorescent detector, producing the final image.
That's why all electromagnetic lenses by default will converge that beam, and never diverge it.
in holding us together. So it's a staggering advance in science to have a good behavior on that. And of course, being able to, to tame electromagnetism is why people can hear you when you do your podcast because through the miracles of the internet just-- or just electricity running the computers. I mean, this is a case if I can get on a small soapbox, where people back then said, "Well, why are you messing around with magnets and
And at, by that time, people had realized that there are four distinct forces that do not seem to be connected. One is gravity, two is electromagnetism, and those are things people are relatively familiar with. But there are two other forces that only have any real importance inside the nucleus of atoms, which is why most people
The way that could happen is if these forces were transmitted by a particle moving from one subatomic particle to the other. In the case of electromagnetism, it's the photon. In the case of the weak force, we call them now the W and Z particles. So the idea is that Higgs and his colleagues came up with is saying, "All right,
variety of means, physical means, those particles. You push them together. The most common is called laser inertial fusion. can't do these electromagnetic pinches, but we now have inv- this new thing has invented the laser," which turns on in nanoseconds.
Maxwell's equations in electromagnetic stuff for everything we do in electromagnetics, we have Einstein's equations in general
And then in the electromagnetic field, for example, let's say like an ocean, and that ocean has waves.
And all electromagnetic phenomena in plasmas exist because of these small departures from strict neutrality.
All you have is electromagnetic radiation of different wavelengths and so on.
Even just the electromagnetic spectrum at that point is wiring us further.
waves of electromagnetic activity across Troms County in a little minibus.
So this is electromagnetic radiation that bounces off objects and hits specialized receptors in the back of our eyes.
So all this is electromagnetic radiation.
regime of the electromagnetic spectrum.
So just as electromagnetic waves are produced by moving electrons, my fist here is producing gravitational waves because I'm moving it about.
And if it can exist for an arbitrary long time, it can travel from here to Alpha Centauri before it's absorbed. So the fact that electromagnetism is a long-range force is uniquely related to the fact that the photon is massless, in this picture. OK? And this photon, because you can't see it, it's called a virtual photon because it doesn't really exist.
And it is one of the most promising channels for the Higgs discovery when the Higgs mas is relatively low, between 110 GeV and the 150 GeV. Thanks to the electromagnetic calorimeter, photons can be clearly identified. Furthermore, their energies could be mirrored with excellent resolution, from which a quantity called two-photon mass can be reconstructed
We know electromagnetic radiation attenuates with distance.
so much really hard electromagnetic radiation around-- it's hard to see how life could exist.
They were electromagnetic. They were slow in a manner of speaking because they weren’t electronic.
because you're getting electromagnetic radiation which is a classical force field constructed from many many bosonic
Because it suggests that the electromagnetic and gravitational potentials can influence reality at the most fundamental skill, even when all the fields are exactly zero.
There was a flaw in the electromagnetic lens, he wrote, that was completely unavoidable.
But in about the 1860s or so, James Clerk Maxwell took all of those ideas that had been percolating around for the previous 50 years and wrote his laws of electromagnetism, and they're really fascinating. If you look at the laws of electromagnetism, they are-- they're differential equations or inter- integral equations. But basically, what they say is on one side, you have a bunch of terms that have electricity in them,
work, and so that's why we study forces. So there are the various subatomic forces of which we're familiar and for instance, electricity and magnetism are components of electromagnetism, which then governs the behavior of things like-- This is amazing. Electromagnetism explains, of course, electricity, magnetism, but it explains how light works.
equations." And that had to be, I think, very persuasive. And of course, electromagnetism also plays a really significant role in chemistry because after all, atoms are held together by electromagnetic forces. There's more to how atoms work. There is all the quantum mechanics stuff. But if you did not have electromagnetism, or if electromagnetism was very different, then atoms would be very different. So it plays a very big role
atoms are held together by electromagnetic forces. There's more to how atoms work. There is all the quantum mechanics stuff. But if you did not have electromagnetism, or if electromagnetism was very different, then atoms would be very different. So it plays a very big role in holding us together. So it's a staggering advance in science to have a good behavior on that. And of course, being able to,
that's where we were. There were the four forces. So we move ahead, and in the late '50s and early '60s, some people were thinking that maybe the weak nuclear force and electromagnetism actually were the same. So they were working on trying to bring together these two forces to show that they're connected.
