  • Where is video 11??

  • This had nothing to do with the photoelectric effect.

  • Totally awesome

  • White version of steve urkle lol

  • To see a video like this with only 9,138 views at this point in time is upsetting.

    I'm only 15 and I LOVE quantum physics.

    It would be nice to see more people take an interest in it.

    As much as I enjoy it being an exclusive hobby of mine among my school peers, I'de like to see the community for this sort of thing grow.

  • Hey... Please come to my school and be my physics teacher!!! You are the best teacher I've ever seen you seriously know everything and retrieve it from your brain very well

  • Great job. You are a good teacher

  • skip to 2:30

    save time

  • nice

  • thanks for help you are doing a great job

  • Maybe zoom out next time...half of the time you're talking off screen :S

  • @ibajem your right and i dont believe that about the electron its just my observation so far of what i have seen and i was just trying to get a physics professors view and i hope you get to falsify a theory i think science needs some mavericks.

  • @ibajem it still doesnt fall to earth when they measure it as all mass does my conclusion is it has no mass

  • @ibajem you can eject electrons try cathode ray tube like in old TVs and you can capture a single using a penning trap.

  • @ibajem again i am talking about when they are ejected into a ultra low vacuum not inside matter and since most chambers are metal that they are contained in which act as farday cages no charge can effect them while they are in there and an acceleration of 9.8m per second is not to small a force to observe.

  • @ibajem But all things fall to earth at the same speed

    sure they may be jostled around by some force but the

    net movement would still be towards earth and even if

    they were waves like photons they would still be

    effected by gravity.

  • @ibajem yeah ok but does that mean they dont have mass

    in the classical sense since all mass falls to earth?

  • No i mean when they are in free space they dont fall to earth.

  • why dont electrons fall to earth?

  • Your videos are incredibly boring... I'm not actually sure if you covered the promised photoelectric effect I stopped after 6 minutes of general waffle. Much of what you said could have been summarised quite succinctly without the need to delve so deeply and you would have still given the same if not a better understanding. Also I found your general mannerisms and presentation quite irritiating. Thumbs down from me.

  • thank you for all your videos! you're a fantastic teacher.

  • If they ever make a biographical film about the life of Jon Cryer, they should definitely give this guy a call.

    Anyway, this is a nice lecture. All the haters should try making a video about this subject themselves and see how well they do.

  • all ur videos rock. greatly appreciated.

  • thanks a lot for the videos(:

    even if they are a bit boring, they HELP

  • your videos are to long. you need to just get right to the point

  • Thank you so much for putting these videos up here ;D

  • Its Greek. Foto is light , and in the word photograph, graph comes from another Greek word, graphi, which means "to write". Isnt that the perfect description of a photographs, to write light.

  • the man seems to know his stuff!

  • GAY!!!!! boring.. i would fall right asleep in your class.

  • totally agreed.. I feel as if this guy is just reciting a friggen textbook.

  • teachers need to do more hands on assignments. not read half asleep
