  1. Everyone saying "i understand it" ironically are misunderstanding the quote. By "understand it" feynman meant have an intuition for it or know all the underlying reasonings for why quantum mechanics exists. Not know how to find the energy levels of an electron in an infinite potential well or how to use perturbation theory; that isnt "understanding" quantum mechanics, thats knowing how to use it

  2. you guys only get taught at 3rd year? We got some basics in first year and got more in depth by second year

  3.  @subhandin3435  Oh fair, yeah our first year was basically highschool although (my memory is a bit faded) I think they introudced the general concept of a wave function and some basic properties like orthogonality and normalisation along with discussing some of the easy to understand experiments like double slit stuff. Second year we got a bit more into particles in boxes and things like tunneling and uncertainty principle then this year we got more into particle physics and perturbation theory as well as applying qm to things like electromagnetism

  4.  @xopha  Kind of, but observation does change things. In the double slit experiment if you fire a single electron at a time through the slits, it still forms a diffraction pattern, but if you put censors in the slits so you know which one it passes through, it no longer creates a diffraction pattern

  5.  @jorgepeterbarton  information is transmitted between particles through the use of virtual particles

  6. @bronzedeuce thats not what OP was referring to. If you have a technique for measuring which slit each photon goes through, the diffraction pattern no longer appears

  7. quantum physics hadnt been written by them, they just had similar ideas. In the scientific community saying 'observation leads to reality" is completely meaningless and worthless unless you have math and experimentation to back it up

  8. depends on what you mean by understand

  9. we dont "know" how anything works, we just have best guesses

  10.  @billyt8868  Im actually a physics major whos graduating this year, we do a lot of work with quantum mechanics. Ill be the first to admit I dont know even close to everything there is to know about it, but I know a damn sight more than most of the public.  How can my comment be proof I know it superficially when to demonstrate I know it thoroughly would take far more than a single youtube comment.

  11.  @billyt8868  Made it easy for you yet you didnt say shit

  12.  @billyt8868  what, because i say i have a degree in physics? Youre the one who brought up my knowledge. Whats more of a joke is you saying its easy yet still being too incompetent to do whatever is "so easy".

  13. @bronzedeuce no, its just particles exhibiting wave like behaviours.

  14. ​ @jorgepeterbarton  Assuming I passed my exam a few days ago im going to be graduating with a physics degree in a couple months and I smoke weed and drink often, have taken shrooms, ket and mdma. And can assure you many others that Ive met (even the ones smarter than me) have at least tried drugs also
