    Just to say how grateful I am for your video's - I am nearly 70 and I took my Applied Maths degree many years ago and seeing your lessons has contributed to a decision to sign up for a second degree this year in pure maths. My dad was born in the latter part of 1899 and I often wonder what he would think of seeing a guy teaching maths all the way from Australia whilst he was sitting here in the UK - pondering the wonders of the internet is something your average high school student may not think about all that often. I'm sure to them the wonders of modern communication - all based on mathematical modelling and thinking - is just an everyday occurrence. May your excellent efforts continue.

      The internet is wonderful isn't it? Where I'm from easy access to science and math education is not possible, yet I now get to have top quality education without leaving the comfort of my home. It's amazing! :D

    I’ve been watching the videos in your Random Variables playlist and I have to say, I haven’t thought much about the Statistical applications of Calculus until I came upon it. I’ve been really liking this series. Keep up the good work!

    What happen if we take modulus of x-mu instead of squarring?

      It's a good question and is related to least squares regression. But I too don't have a crystal clear understanding of it. Would love to hear his explaination.

    6:25 Why can't we use |x - μ| instead, in the formula of variance? That works too right?

      Yes, perhaps even forge a connection between number theory and algebra, with cyclotomic polynomials. Then again, in all of his videos, he is adhering to the curriculum, wherein number theory doesn't appear so frequently.

      Ezekiel 25:17
      The path of the righteous man is beset on all sides by the
      Inequities of the selfish and the tyranny of evil men
      Blessed is he who, in the name of charity and good will
      shepherds the weak through the valley of darkness
      for he is truly his brother's keeper and the finder of lost children
      And I will strike down upon thee with great vengeance and furious
      Anger those who attempt to poison and destroy my brothers
      And you will know
      My name is the Lord when I lay my vengeance upon thee
