    711,000 people viewed this and learned at least a little bit in a very short time. It was a free class taught by an extremely educated man. Imagine the world we would live in if we had this kind of access to every class

    Notes about lecture:
    conservation law
    conserved quantaty
    allowable laws of physics, allowable rules
    25:40
    non-allowable law (in classical physics)
    can't retrodict the past (opposite of predict)
    non reversable
    if reversed, unpredictive (don't know this or that comes next)
    29:20
    predictive one way, not retrodivtive other way
    not reversable, "I" don't call it irreversable
    30:10
    classical physics doesn't allow probability
    conflicts with the rules of classical mechanics
    quantum mechanics are not deterministic
    ambiguity in knowledge of initial condition, so from this statistics in classical mechanics despite deterministic
    33:30
    how precise do you know the initial condition, this determins how far you can predict the future, example three day weather forcast
    other way around, if you know how far you want to predict, then you can determine how exact you need to know the initial condition
    35:50
    allowable, if every state has one incoming and one outgoing arrow
    next example: point particle(s) moving in space
    37:30
    first some preliminary mathematics
    vectors, coordinate systems
    coordinate system: describing space quantitatively
    space with three dimensions/coordinates
    but we are perfectly free to think of systems higher dimensioned or lower dimensioned
    38:10
    we are interested in describing the basic pricipals, so we don't have to restrict ourselves to specific examples
    a particle can move in one dimension, it can move in five dimensions, but for now we use three dimensions
    39:30
    three coordinates, doesn't matter where we put the origin, but it's easiest to put it at the (? 0 location)
    the three axis are mutually perpendicular
    label e.g, x, y, z or x1,x2, x3
    40:00
    still ambiguity about the rotation of the axis, which direction they go in
    fixing the origin, we also have to fix the orientation of the x,y,z axis
    theres a convention, right handed coordinate system, if you pick x and y, still need to decide is z pointing in the blackboard or out of it, we settle at right hand, x thumb, y inex finger, then z middle finger points out of the board towards us
    this is the right hand rule
    another convention, for distance we choose units
    41:50
    point is labled by x,y,z, thats also how we describe a particle
    43:10
    what is a vector
    has both length and direction, for example a position of a point, relative to it' origin, magnitude is the distance, and it has a direction
    don't think of a vector of being located anywhere
    43:55
    vector is the same, no matter where it is drawn in space, doesn't need to be drawn in space
    vector labled by bar on top, more precise a little arrow
    it could e.g. be velocity, it could be acceleration, it could be an electronic field
    it's got, length/magnitude, and it's gotndirection
    47:55 (see formula) length equals square root the sum of squares of its components
    adding vectors, multiplying vectors by numbers
    53:30
    VectA+VectB=VectC
    VectA*VectB=AMagnit.*BMagnitude*cos(winkel feda) "the calculated dot product"
    the product of two vectors is not a vector, it's a number
    1:00:00
    we can display the dot product in component form
    VecA*VecB=Ax*Bx+Ay*By+Az*Bz, you can prove this with a little bit if trigonometry
    VectA*VectA=AMagnt.*AMagnit.
    1:08:40
    The velocity is the time derivative of the position
    Dot means derivative with respect to time (so this does not have to be writtenover and over again)
    Velocity is x of i dot (x1, x2, x3 for the coordinates)
    1:13:50
    acceleration is derivative of velocity or second derivative of xi, so it's written x with 2 dots
    X - position
    V - velocity
    a - acceleration
    r-Vector for radius, positiin vector
    1:16:00
    Formula of an object falling in gravitational field with constant acceleration,
    xt=a+bt+ct2
    uniformly accelerated particle, that has acceleration 2c
    1:18:00
    Circular motion
    x+y achsis, the angle increases linearly
    feda=omega*t
    2Pi/omega=period
    omega is the angular frequency
    X=cos(feda), y=sin(feda)
    derivatives of trigonometric functions
    velocityX=-omega*sin(omega)t
    angle between velocity and position?
    more on velocity, acceleration, calculated ways for this shown

    I remember watching videos like these before college, which definitely kindled a passion for physics and math deep inside me. Then I also started reading advanced books, which were not even part of the course syllabus, for example the famous series of books published by Lifshitz and Landau.
    Among other things, I published the step-by-step solutions to many of the classical physics problems in the first book "Mechanics" in an online course on Udemy (called: "Multivariable Calculus and Classical Physics problems"), which deals with the mathematics and physics of rigid bodies, non-inertial systems, and much more. This is to say that videos like these can be very helpful in inspiring youngsters to appreciate physics.

    Thank you Leonard and Stanford for this. The extras and insights mean a lot. You could lean this stuff from a Dover reprint, but learning it on a trajectory towards Scrodinger and company really helps one focus on what counts. I have been able to make quantum work for a long time, but I find myself returning to the roots over and over again to regain a sense of what I'm actually doing. I think lecture series like this are invaluable for contributing towards a future in which a significant subset of us understand what the world we can make claims about actually us.

    I had lost my way and my love of physics due to depression. Decided to take a break from my astrophysics studies for a year. I think I will spend the year going through his lectures just to see if I can fall in love with physics again.

    Confused? Sloppy? Look at his lecture on 'Demystifying the Higgs Boson' - Of all the lectures this was the clearest overview of all of the great rash of such lectures that came out this year. I find the lectures leave me just enough to think about and sort out myself. I am a big fan.

    Yes, but perhaps the world is full of people who do not have the same grasp or perspective. Plus, one can never over emphasize the basics. This is what separates great teachers from ordinary ones. I find that a lot of the students brush through the basics and find later that they do not have a deep understanding. The concepts of state/phase space are actually not as simple and are so critical in understanding a lot of the world, it is worth spending some time on.
    He is a great teacher!

    The point of using modulo arithmetic is that you don't even need to assign value 6 on the dice to 0, because 0, 6, 12, etc. are considered the "same" element (they belong to same equivalency class).

But there are other things, like music, that you'll want to listen to continually because it just feels good. I hope my lectures are like that... (paraphrased)." Why yes, Professor Susskind, your lectures are a treasure to listen to. Stanford for the win. :)

    According to this source, dice was once the plural of die, “but in modern standard English dice is both the singular and the plural: 'throw the dice' could mean a reference to either one or more than one dice.”

  • @netrapture
    @netrapture 6 років тому +1

    at 19:03, the laws of evolution for die world are categorized by number and TYPE of cycles, e.g. there might be three cycles: one 1-cycle, one two-cycle and one 3-cycle, like his example but there could also be three 2-cycles, so it is more than just the number of cycles - as he hinted.

    How I recommend watching these videos:
    1 Get some notebook paper.
    2 At the top of every sheet, write the UA-cam video's web address, UA-cam Channel & video name.
    3 If Prof. Susskind writes it down, you should also write it.
    4 Write a timestamp on the left side of your notes so you can easily get back to a given subject.
    5 Pause when needed.
    6 Re-watch a section if you're still unclear.
    7 Go to Khan Academy if you need to brush up on, or learn new math concepts ( ua-cam.com/users/khanacademy )

      +potugadu Yeah, I'm in the same situation and I've found something interesting here: ocw.mit.edu/courses/physics/8-09-classical-mechanics-iii-fall-2014/readings/
      Hope that helps!

    • @potugadu5160
      @potugadu5160 8 років тому +1

      +loc tran Thanks. Honestly, I prefer not to read a textbook. I am neither looking to pursue a career in physics nor knowledge of physics required for my job; I am just curious about theoretical physics. So, I wanted to know if I can get by with just watching the lectures. I am willing to put pen to the paper, though. I did calculus based physics in high school & for a quarter in college long time back, and I consider my knowledge of physics & calculus still pretty good.
      BTW, lot of reviews of Landau & Lifshitz on Amazon state that it is not a beginner's book. A book by Georg Joos was recommended instead.

    • @loctran9742
      @loctran9742 8 років тому +4

      +potugadu Totally right! Landau is horrible even for the ones who study physics =)), it rather be a doc for reviewing when you've already cover all the stuff, I think. If you want to dig (but not too deep) in the physics, Taylor's or Thornton & Marion's would also be a good option.
      Or you can wait until the Edx have this course. It's well-fitted to those who prefer self-study, especially to study without reading textbook. :)

    • @potugadu5160
      @potugadu5160 8 років тому +3

      loc tran Thanks for recommending Taylor's book. Read reviews that it is a perfect book for self study.
      An edx/online course on theoretical physic will be great for learning with some structure & discipline, and also to finish the learning/course in fixed amount of time. For me, any study/learning with no deadlines means never completing the study.

    Time in nature might not actually be the abstract of perceiving it as going back or forward to actual events but instead are actually the observable chronological movements of objects that are speeding up or slowing down "DEPENDING" on the level(amount) of gravity and perhaps G-force that's constricting or not constricting the atoms that gives the "OBSERVABLE CHRONOLOGICAL MOVEMENT" we all see around us
