- Physicists started applying these ideas to the quantum world too, realizing that charged particles like electrons also have symmetries. Electrons have a phase, which you can think of as an arrow pointing in some direction, but you can offset this phase by any arbitrary amount so long as you do it simultaneously for all electrons.
He proposed that everything. Electrons, basketballs, people, absolutely everything has a wavelength. And he defined this wavelength analogously to light as Planck's constant, divided by the particles momentum or mass times velocity.
So the professor starts by explaining the setup. Electrons are fired one at a time through two slits to be detected at a screen. Now, because you can't say for certain which slit the particle went through, quantum mechanics tells us it must go through both at the same time.
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
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, electroweak force is real. The way we make it so that there is now an electromagnetic force and a weak force is the force-carrying particle of electromagnetism has no
Since the Higgs field is zero, the weak force particles don't feel mass, and therefore, they can travel at the speed of light, just like the electroweak symmetry theory doesn't need Higgs because that only really applies at very, very high energies.
Since the Higgs field is zero, the weak force particles don't feel mass, and therefore, they can travel at the speed of light, just like the electron and an antimatter electron, and it just does. And we know that. The antimatter electron was discovered in 1932.
- Is everywhere, and we particularly use a type of hydrogen called deuterium, which is a heavier isotope of hydrogen. Hydrogen is typically one proton and one electron, atomic mass of one. Deuterium is an atomic mass of two, which is a proton, which is a charged particle, and it has a neutron in its nucleus, which is an uncharged particle. And so that's deuterium.
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 had been a paradigm shift, obviously. Rock music with the hero on stage was dead. Now it was, you know, dance, electronic music, which a lot of people today think it's kind of simplistic music form, but it's actually a very highly intelligent music form. At least it was in the '90s. People were really experimenting with that music. That was the new
the atoms are made of smaller things. Electrons in orbit around a nucleus that has neutrons and protons and neutrons and protons. They even have smaller particles, particles called quarks. The question is, is that the end of the story? Is it electrons and quirs and
together in a green leaf somewhere, right? Photosynthesis. What your mitochondria do is they they kind of unpack this, and they rip off the electrons one by one, and then they flow them like an electrical circuit. And that happens in the like the 5,000 trillion mitochondria that are in your body. And then when the electrons flow, they need to flow towards something. Just like an electrical circuit, electrons
And the Warburg effect is when a cell, in the presence of oxygen, right? If it wanted, it could use oxygen, flow electrons through mitochondria, and transform energy, and and live a nice social life, uh like every cell in in this social collective does in the body.
like smoking be cancer causing? electrons, right? Very direct parallel with the electrical circuit. There electrons stuck here on these little
like smoking be cancer causing? electron and you're trying to go through the the metabolic pathways looking for oxygen in a mitochondrion, but then
String theory says that what is a proton? What is an electron? They're nothing but vibrations of a string. So from a distance, this looks like a point particle. From a distance, this is an electron. But if you could magnify
Okay. So, a desalination plant takes salt water from the seas, and then through an electrochemical process, turns it into portable water that people can use uh for drinking purposes and for agricultural purposes.
also for people like Professor Fritz Vollrath at the University of Oxford, who worked with spider silk but also the silk of nearly anything. electronic waste is probably more pernicious than plastic waste because look how much of it there is.
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.
they can be in superpositions, you might say, well, electron one is in a superposition of up and down. Electron two is in a superposition of up and down. Quantum mechanics says there's not two separate wave functions for the two electrons; there's only one, and they are entangled in the following way.
They've been doing it for a while. Electronic music-- are you talking about Ableton and those kind of thing?
Sin embargo, si les dices-- Bueno, sin embargo, sabemos que sí se procesa la información de que hay algo porque uno, se puede ver en el cerebro con un electroencefalograma. Y 2, si les preguntas en qué casa preferirías vivir, siempre eligen la casa sin el fuego. Sin embargo, no lo perciben conscientemente.
Electronic health records were introduced.
Electronics, especially in the 1970s, were not ready to operate at those kinds of conditions.

Electronic devices such as phone, radio, and TV emit electric waves and so do the celestial bodies. Astronomers using electric waves to observe are called radio astronomers, like myself.
