I'm impressed and grateful.>> <<@syaoransakura8839 says : I am double stupid>> <<@Comenter0999 says : 2mintues in I’m lost>> <<@OfficialJoeyC says : not sure how i ended up here, but im enjoying this>> <<@YAYATUBE. says : Hi>> <<@jadem8052 says : I can never get tired of learning with crash course !!!>> <<@Sebastianmaz615 says : Never noticed her pronunciation of the letter "h" until it was brought up. 😆🤣>> <<@meaww7373 says : 🤔>> <<@VDcharlie says : Reddit trying to teach me Quantum mechanics>> <<@norel457 says : Why am I not understanding this clearly?>> <<@Munna_Choudhury02 says : Hi>> <<@aperson2020 says : On a serious note, i have a masters degree in Physics from 1982. I have studied QM. I will admit i didn't quite get it fully. But i think the truth is, after watching over 50 plus videos on YouTube, QM has not been taught well by these geniuses. They cannot simplify it for us common people.>> <<@aperson2020 says : I couldn't understand a word. She was speaking too slowly 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣>> <<@Al-cynic says : why is this aimed at 12 year olds?>> <<@FaresMohamed-mi1vp says : 3.51 error - "Hydrogen Attom">> <<@bigyeticane says : Higher dimensionality limits the framework of human understanding. I appreciate that scientists are intelligent enough to see this barrier/hurdle. There is only so much we will be able to solve without finding away to evolve how our consciousness processes information.>> <<@ringo4543 says : Trying to understand quantum mechanics makes me so angry like if I think about it for more than 1 minute I start getting irrationally angry at all quantum mechanics and wanting to actualy blow them up>> <<@Igris_Gladius says : my teacher told me to write down the points, do you guys have any?>> <<@primovid says : Watch this video at 1/2 speed>> <<@marccondarcure1698 says : Where's John :(>> <<@eternalmaximum6899 says : Really thing I don’t understand the reason for my life wasted I should not have been born as a Capricorn>> <<@zidaneprendergast9815 says : Can light source also travels in Ray>> <<@Naughty-jq2gg says : Thank you❤🌹🙏>> <<@bubbalandbeau9872 says : Huh?>> <<@aminakonarbayeva4005 says : 3:55 Let's just say THANK YOU to Mileva Maric Einstein, Albert's wife, who did most of the calculations, worked on their common researchs and actually helped to come up with this theory. Credits to you, Miss Mileva Maric Einstein>> <<@mrboombastic_69420 says : Da fuk i just heard. It sounded real cool>> <<@JOHNTECH112 says : woh ,woh ,woh reduce the speed , you are explaining , your not catching any bullet train>> <<@Lucky10279 says : The idea of light sometimes behaving like a particle and sometimes like a wave is, at best, a misleading oversimplification. I can't really blame Crash Course in particular, as it's a very common explanation, but it's wrong. Light is _always_ a wave _and_ it's _always_ a particle. The thing to realize is that it's _never_ a _classical_ particle. In quantum mechanics, the word "particle" has a very specific meaning -- it's just shorthand for "localized wave function." Essentially, a quantum particle is just a tiny wave. A _very_ tiny wave, which is why it often acts like what we think of classical particles. But it's never actually a classical particle. It's _always_ a wave. What the photo-electric effect proved is that light was quantized -- that means it's a particle in the quantum mechanics sense of the word, but honestly, sometimes it's just easier to forget about particles altogether, because the word has such a strong connotation of "tiny solid sphere", at least for me.>> <<@benjy22 says : Great vid>> <<@Imran_sgsM says : I love this mam>> <<@universenerdd says : black bodies exist, theyre called blackholes>> <<@whycantthiswork says : Did Shini just say haych?>> <<@bliss_fullness3218 says : her british accent uhhhh>> <<@PraveenKumar-mb3kg says : I have a got a lot of crazy answers from your channel.... My kind request is you are running up, keep slow to make us understand the concepts.>> <<@deboi525 says : So how much is the work function?>> <<@mitchellbriggs2954 says : Wouldn't a black body be a black hole, the heat of which is produced being hawking radiation?>> <<@mdsharafathossain3767 says : Felt like she had a train to catch after this presentation...thereby she was in such a rush. A question to her.... Could you finally catch the train???>> <<@BB-qr7fz says : "All you have to do is create a few simple tests," she says....>> <<@Redphionix says : So he invented the Planck length>> <<@Redphionix says : Isn’t light energy>>
