    At 8:15 , Jeff says that the displacement vector connects two vectors. Then in the example he gives, there are two masses at those points (scalars) and then 1 force connecting them? Can displacement vectors be between two scalars like he used the example of , or does it have to be two vectors (which would contradict the video) ? I have a misinterpretation/misunderstanding, please correct me .

    • @ProfJeffreyChasnov
      @ProfJeffreyChasnov  2 ปีที่แล้ว

      The two vectors are the position vectors of the masses.

    Hello Jeffrey, I have no idea if you read any of the comments on here, however I was wondering if you could explain a little more about where the I,j and k system comes from.

    • @ProfJeffreyChasnov
      @ProfJeffreyChasnov  4 ปีที่แล้ว +5

      I guess you are asking about the notation for the unit vectors? There was a big argument in the late 1800's between advocates of quaternions and those of vector calculus. Vector calculus won and quaternions are no longer taught to students. The notation comes from quaternions. i, j, k were all the square root of -1, but were co-opted by vector calculus to become the Cartesian unit vectors.

      @@ProfJeffreyChasnov Dear Jeffrey, yes I was. I was also wondering if you have got any videos on just calculus and how to find derivatives? I like your teaching method and find it easy to follow. I don't mean the rules of derivatives but how to find the initial derivatives to start with?

      Imaginary numbers i, j, and k came from Sir William Rowan Hamilton who got his inspiration at the Broom Bridge in Dublin, Ireland. In the past, I had numerous times passed under the bridge on a railway line. I suppose Broom Bridge has rubbed something into me - my interest in maths. It is a two-mouthed bridge, under which there are a railway line and a canal nearby.

    Don’t take offense sir but you’re kind of a J.K. Simmons lookalike. Or maybe lack of pictures of Spider-Man made Mr. Jameson into an awesome physics tutor.
