  • To perform calculations in SpaceTime, we need to understand that the properties of SpaceTime are different from Euclidean space. Here I discuss 5 basic differences between them
    00:00 Introduction
    02:15 Pythagoras Theorem
    12:00 Null vector & Light cones
    15:59 Circles & Hyperbolas
    20:14 Projections of a Vector
    27:00 Rotations & Lorentz Transformations
    34:00 LT as Hyperbolic rotations of spacetime
    Once you understand these simple differences between performing calculations in Euclidean space and Minkowski Space-time, you will be ready to show how various consequences of Special relativity, like Time dilation, length contraction, simultaneous events, Doppler shift, Velocity additions etc can be simply demonstrated from space time diagrams.

    Thank you, sir, for this exemplary video comparing the mathematics of Euclidean and Minkowski geometry. I am especially grateful for your explanation about the negative sign in front of the temporal term. I have searched several textbooks and educational videos for an explanation to this, but none of them ever explain it. The way you explain it gives a certain intuition into the mathematics of spacetime that would otherwise missing from many other sources.

    • @saicharan9708
      @saicharan9708 2 ปีที่แล้ว +1

      Ya I think it should have been clearly mentioned... We should not visualise the axes to be perpendicular to each other.. In fact the axes keep on changing the orientations according to the observer's velocity so as to maintain the invariance of space time under Lorentz transformation (basically keep light speed constant)

    In general physices lectures on utube two types
    1) 11th and 12th level (u wont get taste of physics . They are oversimplified to some extent atleast.
    2) pg level physics lectures by nptel.they are difficult to understand by engineers and science students(by average students.they are big in number)
    So bsc level physics lectures are most useful for bsc and engineering students.like berkely physics course books and kleppner mechanics books.

      We choose CT so that the worldline of a light photon is a line with slope 1. Thus light cones divide the space time region symmetrically, leading to ease of study. Also the spacetime interval contains "CT"

    In a previous video about relativistic velocity, you claimed that this statement must be true: m1*u1 + m2*u2 = Mv; but you didnt explain it. Why should the momentum of the colloding particles be calculated based on the reference frames velocity? They might have velocity in addtion to the reference frame, which would add to the total momentum.

    We talk about c (speed of light) to be invariant, under the second postulate of Einstein’s theory of relativity. But we know that there is no pure vacuum in space time, neither an observable stable antimatter in the stable universe. In such cases, doesn’t Minkowzkie’s space time interval, fail to inform us about space time ? Because, speed of light decreases with respect to increase in density and density increases wrt. decrease in the distance between a point and the gravitational center of a collective mass ? How do we factor in density of space (which is not constant throughout space) in Minkowzkie’s diagrams ? How do we factor in speed of light in different densities wrt. space time ? How does, ionospheric densities factor in, while deciding geostationary orbits of satellites ? How do GPS and GLONASS factor in space time dilation ?

    • @-_Nuke_-
      @-_Nuke_- 2 ปีที่แล้ว +1

      That's why we should stop talking about the "speed of light" and talk about C as a "naked" constant and invariant number.
      Everything in the Universe moves at the speed of C in SPACETIME. Regardless of the pressense of a vacuum. If you "combine" your speed in time with your speed in space (from either yours or someone else's perspective) using the Lorenz factor γ, then you should always find, that their combination gives you the number C.
      So everything in the Universe travels at the speed of C in spacetime. (again, not space, not time - C in spacetime)
      But even if you have light traveling inside lets say... A glass of water - light is still traveling inside the water with the speed of C. The only difference now is, that the distance is bigger for light to travel from the one point of the glass to the other inside the bottle - because of the pressense of water... The thickness of the water makes light (traveling at C in space) to take a longer time to make that distance because it has to also move through the thickness of the water that before wasn't pressent in an "empty" bottle.
      Light travels at C REGARDLESS of vaccum.
      For example...
      I travel at 50 km/h with my car... If you put me inside a bigger road, I will take longer to complete it, but my speed will remain the same...

    Way you do not make the comparison between the Minkowski 's geometry with the Riemann's geometry with are both of them children of Einstein work and they are completely Minkowski vs Riemann. I have at list 3 huge differences which made the mathematician and friend of Einstein Mr. De Sitter to pick up his hands and to said that space and time is impossible to work together a fabric and he was forced to break it when he worked for the Universe of Einstein-De Sitter. I am surprised that you don't know it. Indus are great mathematicians.

    The problem is that time is not a scalar. Time is a compact dimension. If time was scalar one would be able to move in time. We don't. We like to believe we are mooching forward in time at c but the universe is spinning at c and time is a compact dimension one single Planck second in size.
    If time had accrual duration we would be able to move in it similar to our movement in space.
    Minkowski spacetime was a stop gap.
