View full lesson: ed.ted.com/lessons/how-does-an...
An atom smasher, or particle accelerator, collides atomic nuclei together at extremely cold temperatures, very low air pressure, and hyperbolically fast speeds. Don Lincoln explains how scientists harness the power of both electric and magnetic fields to smash atoms, eventually leading to major discoveries about the matter in our universe.
Lesson by Don Lincoln, animation by Sputnik Animation.

the thing is when mathematicians or physicists "complicate" a topic, theyre usually trying to express the full nuance of that topic. 9 times out of 10, it sounds like they're complicating things but really they're just trying to give you the full picture. Nature is absurdly complex and a simple anecdote cannot fully express that complexity.

Ten feet is near (but not exactly) 3 meters or so. To convert F (Fahrenheit) to C (Celsius), just take the F temp (-456) and subtract 32. Now you have -488 degrees. Now multiply by 5/9. -488 * 5/9 =-271.11111...

I wouldn't say that is an example of how primitive we are. It's actually quite ingenious. We want to know what is inside these tiny particles, but we can't cut them, since we can't create a knife that has an edge finer than an atom. Also, we have to overcome the strongest force in the universe that holds these particles together. So, we decide to use the particles themselves and smash them together so that they break apart. We can then examine the wreckage to see what they are made of.

For the accelerating portion (with the positive and negative plates hooked up to a battery) if an electron were being accelerated then on its way back wouldn't it be repelled by the plate of the same charge

@threeuniquefingers 8 ай бұрын

Indeed! I think what they do is use the same principle working on a DC motor. Turn the electric field on when the particle enters between the plates. Doing so will have a double benefit, the positive plate will repel the electron and negative will attract. And than turn the plates off again…tho it’d be hard to time it correctly as the e is moving quite literally in light speed…

The description of the "acceleration" part is wrong as if you do it as described the particles would brake between your accelerating structures. In a particle accelerator RF is used in a cavity (in the LHC Supra-conductive) to accelerate the particle on the edge of the oscillating RF.
