    Seems to be an excellent teacher. I am 77 years now and was a student of biology in my younger days. Unfortunately I had very limited exposure to mathematics. I followed now his lesson. on logarithms. It is interesting. Had I learnt mathematics from a teacher like him in my formative years I would have fared even better in my Physical Chemistry paper way back in 1967 when I was doing my post graduation in Soil chemistry. Such teachers can create interest even for biology students for whom mathematics is dreaded subject .

      Another thing that’s sad is that nothing has changed since 1967 (or even before that), neither the boring lecturing approach nor the attitude and ego of teachers and the regimentation and control of school. The boon however is the Internet, knowing that I have an escape and I can go home and grasp a concept leaves me with such less stress. I always wonder how people such as you used to cope without the Internet. Anyways, incredible how you still have the thirst for learning! You just inspired me:)

      Oh i wish i could learn in countries that i love because the people their really got this kind of motivation to teach people in smooth way...as for me in middle east however...the curriculum is just so rigid and the teachers are horrible...im bachelor now and taking math at a filthy educational center just to learn the basics of math and not the whole thing...im just taking all in a rush because i bachelor and i have to finish books before my exam...is just feels off...i really dont get people in contries such the US or UK however...never appreciate the gifts that they have during there education process...all taken by ease and great teachers...i just want to make my dream come true and learn my favorate subjects in the countries i love...feel like a student...uh just someday.

      Actually none of his videos are monetised, even those over 10 mins. He is pretty much like Khan Academy; non-profit. That just makes me sad. He teaches millions of students for free, and chooses not to gain any salary. What a lovely, humble and intellectual human being.

    I start to hate mathematics when I became a junior high school student. And it begins again when I got entered senior high school. I looked for the functions, why they can put that formula, but my teacher always skips that concept and tell us to remember the formula. But now, after I watched the speech of Josh Kaufman about 'the first 20 times' I start to jump into mathematics again and I find your channels. I enjoy learning, and I was like Oh-what the magic you give to me sir? Cause I used to doze off or lying on my bed. Thank you, I'll try to start loving mathematics again^^ thanks for being the 'good teacher' just like what I think never suit in a person surrounding me for this time.

  • @davidplanet3919
    @davidplanet3919 3 роки тому

    In the 70s the main purpose of learning logarithms (base 10) and the addition rule was to expedite multiplication. There we no calculators so students needed an approximate way to multiply values together. The logarithms were provided in printed tables. The generalisation to different bases came a bit later. Sometimes in physics calculations where large numbers need to be multiplied, the logarithms will be added instead, even today when calculations are done on computers. In binary computers floating point multiplication uses the addition rule, multiply the fractional parts and add the powers of 2. So this is very relevant today. Learn your logs students.

    2^3 = 8 2^4 = 16 The 3 and the 4 are indices - ALSO KNOWN AS LOGS.
    So when we multiply the 8 and the 16, ADD the logs ie. 3+4 = 7.
    2^7 = 128. QED.

    @Nobody-th3qc 5 років тому

    it would be a lot simpler to find the answer if you were to make the two squares equal. they'd both have diagonal lengths of 10 and angles of 45 degrees so you cold you sin rule to find the lengths and then find the area. 10= x/sin 45 . x= 10 x sin45 . x= 7.01067812 . Area= 7.07067812 squared x 2= 100
