    Anyone interested in the history of science will find this film valuable.
    Thank you AT&T

    Such deep and true Knowledge is impossible or at least rare to find nowadays

      what are you talking about? this is in college physics textbooks, it is pretty standard.

      ​@@nobodynowhere7163 College textbooks are limited text , but Teachers of present days don't Bother to Explain anything intuitively they just wants to do formalities but Nowdays RUclips is best Alternative to find Best . Do you think all schools and colleges teaches science to students as of in MiT?

    The AT&T Archive series it top notch, thank you so much for sharing this!

      I second that! Not a bad video in the lot! The very epitome of how useful RUclips can be as an educational tool. Aside maybe from opencourseware etc.

    Everytime I watch old informative videos about something in science, (much like what this video is) I'm amazed at how incredibly concise they are. It makes me wonder why the more updated science videos are so difficult to understand.
    Well, either they really knew how to explain these things they know or I know more so I understand better. hmmm... I can't tell.

    • @omsingharjit
      @omsingharjit 4 года назад

      Yeah you are rights , now days people's are inefficient to explain anything from scratch to edge.

      I think in large part it boils down to the basics. For instance they simply did not know all we know about Lasers these days so if someone wished to make a 55 minute video on lasers these days there is much more information they need to compress into that time slot. Here he has 55 minutes to explain only the very very top surface of laser functionality. This is good and bad and what one should do is seek out these sort of things for topics they don't currently know or understand and only after getting this overview move on to more modern and complex explanations of a topic. Doing so one will find the more in depth modern stuff was not as confusing as it first seemed because now that you have the basics stuff like Population inversion and Three level systems will make more sense. Without this overview however it will seem like the modern video is speaking alien language.

      It's a matter of depth of knowledge. You only truly understand a subject when you can explain it in a way that a person who does not know the subject can understand it.

    The viewer is asked to forgive the cadences and stiff upper lip delivery indicative of a posh Oxbridge rearing.
    It turns out that Dr. Garrett passed away just last spring. Nice to have listened in at least one of his lectures.

    If you strike my Fork enough times I get spontaneous emission too.
    You need a much higher pumping intensity to make Ruby oscillate. SMH..... 🤐

    Благодарю Вас за видео. Здравствуйте, интересно можете думать не по шаблону?
    Как воздух носит волны звука. Так и гравитационное поля носит волны света.
    Данные выводы возможно подтвердит экспериментально:
    1. На поверхности земли, его гравитационным полем, сносим направлено скорость света в волокне у оптических угловых гироскопов которые, расположены симметрично на специальной платформе и движутся по кругу без угловой скорости.
    2. Используя два равных источника твердотельных мазеров, установленных встречно на периметре диска и при помощи отражателей и интерферометра Майкельсона возможно построить опыт определяющий скорость на периметре диска если он вращается или скорость движения автомобиля в «ДОМИНИРУЮЩЕМ ГРАВИТАЦИОННОМ ПОЛЕ ЗЕМЛИ.
    Вопрос. Почему нельзя при помощи этих же инструментов также определить на Земли её скорость по периметру орбит? Скорость света константа - но в рамках доминирующего гравитационного поля; планеты, звезды, галактики, скопления галактик … . -
