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.

What a fantastic program. Despite studying physics [mostly on my own], despite having physicists as friends, including-by coincidence-3 Nobel laureates, I learned more here about the early history of QM than I had previously. You guys are from Montana? I now have a new impression of your state. Your intelligence is over the top!

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)?

That is quite a stretch. That is like saying if scientists used a condom in an experiment that condoms are responsible for anything associated with that experiment. That is definitely a preschool level over simplification purely aimed at getting views. I really hate what has become of society where everything needs to be hyped up to try and make it sound exciting.

Remember that all knowledge that has come from the study of sub atom particles are models. Models that describe our understanding about how thing work. Models that work when we use them. But these models are not the real truth, they just helps us to understand. I do not think that the human brain or brains are capable of understanding the real sub atomic world. Are electrons particles, a field or something quite different? Is Higg's boson a field, a particle or a part of a string from another dimension? We all conclude on what we can measure in one way or another. We can not measure what is beyond our imagination. My regards to the people that are using their life to understand /JD
james yeung
james yeung Il y a 4 mois
You just don't understand quantum mechanics,not the rest of the world and please don't quote yourself as you'd get called out,in qft each particle in the Standard model has its own field and the mass is just the energy required to "create a particle", it's not actually a particle just some vibrations that appear as particles when we interact with them.

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?
Bubz Bubzington
Bubz Bubzington Il y a 8 mois
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...

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.

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)"?
