Well actually, that’s debatable. The title could go to Archimedes who also calculated pi, but did so during the times of early Ancient Rome. Or it could go to Pythagoras, who developed the Pythagorean Theorem, allowing the discover of pi. The title could go to Nikola Tesla, or Benjamin Franklin, or Schrodinger, or Galileo, or Aristotle, or Socrates, or Plato, or Marcus Pollio. There are millions of candidates for this position, I don’t think we can declare just one person for it.

Thanks mate! Just found your channel and I am loving it.. I am not an academic nor a math ninja but I love seeing these "behind the scenes"! I was actually looking for something you might be able to help me (and many more, I hope) with... I am trying to "understand" the thought process behind reciprocal and reciprocal formula. I have been learning about circuits and was faced with the Parallel Operator/Sum which strikes me as something very "deep" in derivation of formulas and algebra/math itself but 99% of people will only ever copy the formula and solve it without ever understanding why.. How I see it is that by using the reciprocals of parallel domains (in this topic, circuits with resistances) the "formula" allows us to "sample" a new kind of "unit" of that abstract domain where we can then calculate the participation (the % contribution of the total) of each "parallel resistance" in the overall system and the final step (multiply by the volts) will apply each "participation" (the new "unit" / the new "one") relative to the total voltage of the circuit and give us the correct value on that particular point of the system. I have NO IDEA if what I wrote makes any sense, as I said I am far from a math geek just the everyday nerd on youtube. It would be great if anyone could share some insights and/or send me some reading material... It took me forever to learn what are reciprocals, reciprocal rules and see how it's used beyond "copy the formula and replace the variables". Somehow I have a feeling that learning about this thought process might help me a lot with understanding how things actually work. My education never focused on reciprocals, we would learn to multiply fractions by putting one on top of the other and multiply TOP x BOTTOM / BOTTOM x TOP ... again, just another formula we would memorize and repeat (before year 2000)... Cheers from Brazil! Keep up the cool videos!!!
Hello and thank you for liking the channel. I will admit that I am not familiar with the formula on reciprocals as it relates to circuits. I hope you find an intuitive understanding of the formula!
Sounds like a good way of thinking about it. Essentially, you are taking resistances (which don’t add in parallel), converting them to conductances (through taking the reciprocal), adding the conductances (to get the combined parallel conductance), and then converting back to resistance. One motivation for why conductances add is parallel is the following: the conductance of a path times the voltage across that path yields the current that would flow. Two paths in parallel have the same voltage, so the sum of the currents through each path would equal the voltage times the sum of the conductances, so it would be reasonable to say the conductance of a parallel combination is just the sum of the conductances on each branch. Hope this makes sense.
@@matthankins6206 THANK YOU! That was a great explanation and I had not been able to think about it in the "conductance" light. I believe I now understand why reciprocals / inverse numbers are used in the formula. It is because the inverse of the resistance IS the conductance. Beautiful as it all came together! I confess I thought it would open up a new way of looking at this derivation, but it was "so simple" (with your help) that it completely makes sense why it was done this way, incredible thought process. I thought reciprocals would be more of a wildcard in derivations (due to my lack of understanding), but understanding its use in this formula has put my mind at ease. Once again, thank you mate! It's the kind of stuff almost impossible to find the right google search. Cheers!
Basically, the binomial expansion is used to expand a binomial to any power, it uses the binomial coefficient (the combination symbol of ncr), I suggest googling to find out more.
Epic Math Time made a really good video about it. Edit: Did want to note that it was originally supposed to only work for positive integer n; this is why Newton's discovery was novel. For a more rigorous definition, you can use a MacLaurin series expansion.
For (a+b)^x where x isn't a positive integer, we can find an approximate using that formula. Since the square root is ^1/2, we can only approximate it. It only works if x is between 1 and -1 and if x is rational.
I've always wondered how pi was originally calculated. Plus the visual really helps! It's interesting how the quarter sections of the circle match up to the radians of the angle. Just another way to show that math always comes back to prove itself
in order to get expand (1-x^2)^1/2 Newton broke the previous rule of only using the binomial expansion formula for powers that were counting numbers (positive integers) Newton was the first to realise that the binomial expansion formula applies to all real numbers, if you're comfortable with infinite series. Newton took it a step further: He integrated the circle fromula between x=0 and x=1/2, which gave him the area of a sector of angle Pi/12 radians + a triangle with base 0.5 and height (root 3)/2 root 3 is equal to the binomial expansion 2(1-1/4)^1/2 Therefore Pi = 12 x(integral ((1-x^2)^1/2) - (root3)/8) This value converges quite quickly
Just using Pythagoreans theorem, I was able to calculate pi to ten decimal places... I could have gone further but I did it by hand. It took several days and I got bored. It makes me wonder why it was so hard to calculate before Newton when the theorem has been known for centuries. Another thing that blows my mind is that if we know the radius of a circle, we can never measure the circumference and vice versa. We can see the beginning and end but it can't be exactly measured... 🤯
an important thing is that he was the first to apply the binomial expansion to the circle because for that he needed to use a fractionary power, and no one before had tested the binomial expansion for a non-integer n, but newton did and proved he could, that's the beauty of what newton did, expanding a theorem, proving the expansion is possible, start playing with it and using the other knowledge he "created" to revolutionize pi approximations
