You might think that quantum physics was discovered because of some super complicated electron behavior or something, but it was actually invented to explain ovens.

Never upset to see an ad in a video I thoroughly enjoy, but I wish you guys would have let the viewer know when the informational part ends and the advertisement begins. Even writing a more solid, conclusive closing statement would work. Anyway, love the video!

If I heat up a piece of tungsten up to 5500 Kelvin, it should be the same color as the sun, correct? Does that mean the tungsten filament in my lightbulb that puts it's light out at 5500 Kelvin; does that mean the filament in my bulb is 9440 degrees F (5500k)?

I once mentioned the fact that light sometimes behaved like a paricle and sometimes like a wave, sighting the double slit test as an example, and was berated by a "real scientist" for 15 minutes. Am I insane or did this 'professional scientician' not quite understand what I was saying?

Ah he mightve made the same mistake i did. That particular experiment proved particle and wave forms, which ALSO proves quantum superposition. Its too easy to fall into the one experiment disproves or proves one concept frame of mind, all neat and tidy. I thought the double slit experiment just involved superposition myself till i went back and referenced the project.

I think Schrodinger's Cat thought experiment is a horribly flawed way of thinking, because it makes the assumption that only _human_ observation is capable of collapsing a waveform, and ignores the fact that the cat has its own consciousness, and a cat's going notice if a canister of poisonous gas is trying to kill it. If it were only _human consciousness_ that could collapse a waveform, it would mean dinosaurs never really existed, and they're just a figment of out god-like imaginations. Pretty arrogant and homocentric view, in my opinion...

Radical Ideologues: Men and women are effectively the same, gender is a social construct. Science: If some part of the world, even a simple one, says NO to your theory, you eventually have to stop fighting reality. Radical Ideologues: REEEEEEEEE!!!!!

If you want to know more about famous Quantum Physics debates, Albert Einstein and Niels Bohr had some and the story is kind of interesting. They had a rivalry, but they respected each other and Einstein did manage to challenge Bohr successfully, but Bohr was extremely smart and hard to beat. Had it not been for Einstein, Bohr would have had an even bigger ego than he already had, Einstein took him down a peg or two by challenging him with things he could not answer (which was unusual for Bohr). It forced him to think and reconsider his opinions, which made Bohr and Einstein better. Had this friendly rivalry not existed, it would have led to less knowledge. Every day Einstein would come with a new question/challenge for Bohr and most of the time Bohr shot him down, but there were times when Bohr had no answer and was intrigued by Einstein, hence their "friendly" rivalry.

Fuckin' integers... I hate whole numbers... You know that the whole cat violence thing is why you physics nerds never get it right, you can't unify anything. You couldn't unify your way out of a wet paper bag. You are focusing on cat violence way too much. The key is that it's dead puppies all of the way down. If you can't say something nice about cats, say something surreal.

I have a question. How is it that a guy who says, AND SINCERELY MEANS: "If some part of the world, even a simple one, says 'no' to your theory, you eventually have to stop fighting reality. Some assumption your theory makes must be wrong." ... can speak so UNCRITICALLY of the gravely inconsistent explanations and repeatedly failed predictions we have been handed for some three decades or so now, under the heading of "Global Warming (aka Climate Change)"?

For a science show, you would hope that you would do some fact checks and use the scientific process too not perpetuate a myth. The cat in a box that’s only alive when you look at it thing is a journalist, taking something out of context as usual. Leading to people taking it literally. I learned that on joe rogans podcast. What does it say about this channel?

our clearly quantum cosmos expressed in the discrete "whole numbers" mathematics of quantum mechanics gives our complex cosmos a far more uniformly ordered structure for both energy and matter, which point to an Intelligent Creator-Designer, than those hoping for a more mish-mash randomness of an unordered incomprehensibly chaotic cosmos, which is merely "self-existent" on its own (materialism)

Ummmmm, "Max Planck" is pronounced "Mox Plonck", or Mahx Plahnck". It's "German". A "foreign language". Do try to keep up. I can't stand linguistic ignorance.
