Well, it would not make any sense really. He gave you a name for them so you can look them up if you want but there is no use for them to show up here - that's just extra work for no reason. And if you can't be bothered to look them up, then you are not really interested, so we go back to the start and the futility of the extra work required. It is actually a teaching technique - you tell people a very good story, make them interested, then the will go and learn something themselves, which is a more efficient and healthy way of learning. That is one of the reasons why people arguing with Flatearthers are just wasting their time. A flatearther came up with his "knowledge" by "looking for it", he "investigated" and so on. So, psychologically, it is accepted more than if someone else comes along and tries to teach you something, like Earth being a globe. The first part is you "discovering", the second is you being told something. All good teachers actually just aim to get you interested - and then the magic happens, you start learning yourself because you WANT to know, you WANT to learn... not because you have to and some bloke is forcing you to read a book or something. That is why SciShow and many other like them give you a general story, an interesting story, and give you some key names and terms so that you could CONTINUE your search and learning, if they managed to get you interested. Them just giving you everything on the plate is classic school format that is proven to be bad actually.

@@Wustenfuchs109 I suppose, i already know most of the equations as a physics major, I just like seeing them in the video, it makes it more entertaining to me. Though your argument doesnt really make sense if you think about it. You say if people are interested they will look it up themselves and learn it better that way. Isn't looking it up exactly the same as someone telling you what it is, assuming you're interested? Unless you do the work yourself of many centuries of physicists building from the ground up to what we know now then everything you learn will be because someone told it to you. What difference does it make if it's from a sci show episode or from a textbook?

@@foreverofthestars4718 It makes a lot of sense and that is why modern presenters do it. I am a physicist too but I also learned a bit about presenting to a crowd (or simply, teaching mechanisms), that is why I know what it is that these people, and many more channels like them (who get prizes for their educational work). Their job is to get you interested, to dip your toes into the water. Formulas and deeper understanding is for you to uncover. Slapping a formula, without explaining it, is not only a waste of work (people who don't know it, it would not mean a damn thing to them, those who know, for them it is pointless) it can actually repel people who'd feed intimidated by them. But if you don't understand the psychological difference it makes between you looking something up yourself and someone telling you, then what ever I say would fall on def ears. If you want to understand, go and learn about teaching techniques. Just telling people information for them to memorize is actually the worst way of teaching. Telling them just enough for them to get interested and then letting them dig themselves is, so far, the most effective. It is being used from primary school up to the elite colleges where your professor just gives you the basics then gives you a shitload of homework that you CANNOT do with a basic class but he makes story basic but very interesting so you are willing to spend time and get to the details so that you could work out a homework problem. Knowledge gained in that was is by far that of the greatest quality. Doesn't make sense to you? Fine, not everything has to. The fact is, it works.

It wasn't a lottery, it was an educated guess. You can match an equation to a set of data without knowing the reason behind it.

Einstein threw a constant into his equations of relativity because otherwise gravity would lead to a nonstatic universe. He threw it out when Hubble's work showed the universe was expanding, and called it his greatest failure. When it was discovered that the expansion of the universe was accelerating, the equation still holds as long as the constant is positive instead of negative.

dev02ify Pilot Wave Theory has been shown to be wrong.

@zztop3000 anyone saying quantum mechanics makes sense or that they understand it... doesn't actually understand quantum mechanics. That's the thing about it. It doesn't make sense. But it works for what it's used for, so they keep using it until something better comes along.

@@Sanquinity Theoretical physicist Sean Carroll makes a good case for the many worlds interpretation of quantum mechanics by Everett which does make sense, actually (some implications sill have to be worked out though). But as far as I understand it, it's the most plain reading of quantum mechanics that states that there are no uncertainties but all possibilities described by the equations are actually real (the cat is dead and it's alive and there are two separate universes for each... universes branch out with every possibility which means there'd be a lot of new universes all the time) but only when you observe the outcome you find out in which universe you ended up which has a certain probability. The Kopenhagen interpretation is just the standard for teaching students at the moment and has kind of dogma status. The formula works, so they don't care about interpretation. It states that the act of observation makes the probability "collapse" into a concrete outcome. Before you observe, the cat is in a superposition of being alive and dead, whatever that means. If you are working on other interpretations of quantum mechanics because you want it to make sense, you won't be taken seriously, apparently (editors of physics journals have even publicly stated that papers which attempt to interpret quantum mechanics don't have to be read but instantly go to the trash can).

Ah, the "shut up and calculate" approach

Paulo Marques Dude I don’t like or dislike the theory.

Potato.

I don't think he "despised" it - I think he just thought it needed more work. He thought we'd find more down there under the hood, and that in the end it would all be deterministic. And he passed on before Bell and the experiments based on Bell's work conclusively proved that not to be the case.

0 is indivisible to all because interpretation of said divison without context is hopeless. 1 should be a prime. Aside from -1 there should be no prime in the negative. Yeah rules are rules can't really do anything 0,1,-1 are avoided entirely.

Zero is the antiprime since with zero as the top number in a fraction (I think that's the numerator) you can put any other number on the bottom and it will equal the whole number zero.

@@ogungou9 - Any country. Engineers think in terms Newtonian... unless they are electronic engineers maybe or specialized in space exploration. Engineer is a technical career.

@@LuisAldamiz : ​ @Luis Aldamiz : in France, any engineers and science grads are taught at various levels some notions in quantum mechanics too depending on the course/cursus (since their first years after high school, generally in the courses/cursus named Math sup and Math spé, to begin with ...) In fact in France the first notions of quantum physics begin in the last year of high school in Physics when you have chosen a field of science and/or technology at the end of the first year of high school (for the seconde and last year) ... as well as at the first years of university, if you continue in science and technology through university. At least it was like that when I was in high school (I'm 49 now), and I don't think it's any different now. So yes, I'm really baffled by what I'm learning from gthakur17, skeptical even. In France most engineers would not react like what gthakur17 says, unless they are crackpots of some sort talking about electric universe and other poppycocks.

@@ogungou9 - I don't know which is the curriculum now in Spain but I have several engineer relatives, incl. my dad and a brother, and I'm pretty sure they know only very generic concepts about quantum mechanics, at least from studies (they surely learned more from private readings and watching TV/YT). You don't need to know the Schrödinger equation to build a bridge or an engine. It may be more useful in electronics but otherwise...

​@@LuisAldamiz In France when you want to become a physicist, most of the time, you start above all by entering an engineering school for at least 5 years, but after t (some time it's through university) ... So I guess we prefer that our students have a solid general culture, solid foundations in the scientific field as soon as possible ... But now I understand why there is debates in France about how there is too much too soon to learn, for exemple in the two first years after high school (in math sup & math spé for exemple), compare to other countries (let's say Sweden, randomly) that produce scientists and engineers at least as good as ours. We call this burden 'bourrage de crâne' ...

I like to watch these videos and pretend to be smart

We’re all too dumb for scishow

Simple version: Reality gets screwy around the edges, and Max Plank spent his whole life detailing how screwy and in what ways.

Not dumb! You just haven’t gotten a full foundation yet. You may not know all the terms. That isn’t you being dumb. That’s you not knowing something. It’s okay!

Watch the crash course astronomy video for light. It will explain fairly well. Something explaining spectroscopy would work too probably. I will briefly try to summarize what you need to know to understand this video though: Basically, light is composed of particles called photons. When photons hit an atom, they cause electrons to jump an orbit. Larger orbits are more energetic, after all, and light is energy. Anyway, those electrons that took in the light energy and jumped orbits are now "excited." Eventually the electrons will lose that energy again, or become "grounded" and they will emit it back as light. They will then go down an orbit level. You can think of the electron orbit levels as a staircase. You can't go up or down half a stair. You can go up two stairs, or down one stair, but you can't go up partial steps. Anyway, the more energy an atom has, the more excited the electrons get, so they jump up to more higher orbits (aka go up more stairs.) That means when they go back down to ground level they will emit more energetic light since they will be losing more energy. More energetic light has a smaller frequency, hence it is "bluer." That is because the long wavelength end of the visible light spectrum is red and the short end is blue and purple. Every atom has a different "staircase," so they can only emit certain wavelengths of light, and which wavelengths they emit depends on how many "stairs" they went down. You can actually use the wavelengths of light matter emits to identify what atoms it is made of as a result, since different atoms have different "staircases," so they emit light in different spots on the spectrum. This video was basically just scientists accidentally discovering that atoms had "staircases" through math, as opposed to say atoms having a ramp of energy where the electrons could just go up and down an energy amount. So yeah, they discovered atoms can only absorb or emit certain exact packets of energy. These packets are the quanta in quantum mechanics.

While i generally agree with you, weirdness is subjective To (most) humans it *is* weird, because it's not like the everyday classical mechanics we all know and usually love

kzfaq.info/get/bejne/sMmnnrJ3uNiwdn0.html

You see that's exactly what the use of the word "weird" suggests in the first place. It says a lot more about our understanding than it does about the state of the universe.

Interesting position. I feel obscurely it must have to do with the anthropic principle, but my horrible flu prevents me from thinking clearly. I mean, of course it is weird TO US. We tend to interpret the world starting from what we perceive. To understand quantum physics, we need to jump to the abstract understanding of a reality that contradicts all our perceptions. And we arrived to do it way before being neurologically ready to grasp any of it smoothly (if we ever will develop that way before extinction, which I doubt). This is what makes it weird. Then, since the concept of weirdness is a construct internal to the human species (until someone finds a way to ask the dolphins or the tarantulas) and we are studying the universe for our own understanding of it, nor for the Pizzikatelzians' from Ceti Alpha 5, nor for the pandas', I guess we are authorised to call it weird for our own purposes. Aren't we cute, though? Squeezing our limited minds to the last drop to get a glimpse of what we will never be able to experience without resorting to the religious shortcut? I love us. Except when we use the glimpse to make nuclear bombs. Maybe we are not that cute. Edit: I don't own any of the planets named above, which are intellectual property of a Mr Roddenberry.
