- Lecture Date: Tuesday, February 22, 2005. When we explore Nature at distances much smaller than the size of an atom, we find new and mysterious physical principles. At such small sizes, particles are governed by "quantum theory". Quantum theory tells us that some aspects of particle motion cannot be known as a matter of principle. This is a challenge to those of us who would like to do experiments to understand how these particles behave. Fortunately, quantum theory, for all its uncertainty, has its own logic. It predicts patterns in the subatomic world that hold definite information and can be measured to high precision. In this lecture, I will explain how we use these patterns in experiments with high energy particles to learn about the nature of the subnuclear forces and about the structure of the universe. Lecturer: Michael Peskin, SLAC National Accelerator Laboratory.

This is very good - not only did it explain some possible realizations of dark matter, but this really gave me a "feel" for how scientists actually USE those particle accelerators to suss out stuff about the world. Well done!
Start is at 6:14
I got this Thank you
@17:52 I never seen a picture of Einstein with a beard
23:54 Spin of particle
why the 50 min bluescreen at the end?

Perhaps a more accurate way to put it is: This kind of science shows that the universe is governed by probability.
It's more likely that we are currently only able to understand it in terms of probability. There's probably a more advanced math that might give a more exact answer to this stuff but either we haven't found it yet or our brains aren't complicated enough to understand it.
until its not anymore thanks to more advanced science
An atom is in the neighborhood of one hundred thousand times the size of the nucleus length wise.
What PARICL. OF WHAT ATOM. ACCORDING WHAT? PLEASE TELL ME WHAT PARTICULAR PARTICLE.? THE BYPRODUCT OF WHAT? THE ACCELERATION OF WHAT ELEMENT? TIME DILATION IS ONLY POSABLE THROUGH A MAGNET FIELD. EYENSTIN WAS A GREAT THEORISTS. WHEN I OBSERVED HIS UNIFIED FIELD THEORY. WHY THEN DID HEY USE METAL THAT COULD NOT WITHSAND THE EXCITEMENT OF A MAGNET FIELD. THAT MAKES NO SENSE. ARE ARE TELLING ME NOW. HE DIDN'T KNOW HIS TABLE. IT DOESN'T ADD UP. E=MC2. NO KIDDING. I WAS HAPPY WHEN AT THE TIME THAT TESSA SAID WE ARE GOING TO DO IT ANYWAY. QUESTION? DID TESSA KNOWING HIS FIELD OF FREQUENCY NOT KNOW THE EXCITEMENT OF THAT EXCITEMENT. I would work that problem all day, Given the chance of course!!!!
Adding a dash of philosophy to the cocktail, I would say: there exists no nonprobabilistic science of phenomena. Physics cannot deal with things in themselves but only with how phenomena work. It is wise not to forget this when extrapolating from physics to metaphysics, from experiments to the universe as a whole. Otherwise, we are just producing naive realism metaphysics.

Quantum mechanics is simply mind blowing, I can't wait to see quantum computing in a few years.
I know im asking randomly but does anybody know a way to get back into an Instagram account?
I was dumb lost my password. I love any assistance you can give me.

Q
Wonderful! Could you just explain how this disproves the existence of God?
That is the million dollar question. Do you read your Bible. It is a history book nothing else. They that came from the sky. It is a history book in my opinion. They, we're badass. A technology that wasn't comprehend. I have no problem with that at all. I'm just wondering if we can reach that level. That would be great. It's just to bad that people are involved with things that won't get this race off of the ground.. Just wondering. How in the he'll do you think that they came here. Do you think that it was by cayosss, or working together ❤
"If an atom was the size of the Earth the nucleus is the size of a basket ball"
Bull shit.
+Ralph Latham Pay attention. He said basketball court, not basketball.
