History of Calculus: Part 3 - The Historical Motivation

This is part 3 of the series: History of Calculus. Where I talk about the origins of calculus from ancient times to modern history.

In this video I talk about the motivations that led to the discovery of calculus.

Notes:

- 0:05 The work of the ancient Greek mathematicians was forgotten and was confined to libraries scattered around the mediterranean. Almost a thousand years later, Arab and Muslim scholars translated the works of the ancient Greeks and revived some interest in studying curves, and although they made great contributions to the study of curves, they stayed within the limits of the method of exhaustion.

- 0:05 During the 2000 years' gap, mathematicians in India, particularly in Kerala school of Astronomy and Mathematics, made discoveries similar to what we may call today calculus, while their work is brilliant and has elements of calculus, it can not be called calculus. I will make a separate video about their brilliant work in a later video in the series as it gives an understanding of calculus from a different perspective. One based on arithmetic more than on curves.

- 1:13 It is important to note that many mathematicians are not necessarily motivated by the practical applications of mathematics and are interested in mathematics as a form of art, however, when other factors like political, cultural and economical are at play, we can see how the absence of the practical applications of geometry shifted the focus away from it.

- 7:25 Galileo later found that the motion of objects in free fall is uniformly uniform.

- 13:34 Such a rod doesn't exist in nature and is used for demonstration purposes only.

- 15:07 Finding the differential equation of the water from a tap is not possible since it is assumed to be done randomly.

-17:06 The origin of the cycloid is not clear, some historians proposed that it was known to the ancients, while others think it was discovered in the 15th century and others proposed that it was only discovered in the 17th century.

- 20:29 The Copernican model was already known at the time but it wasn't accepted. Another model that also existed was proposed by Tycho Brahe. Tycho assumed that the planets revolved around the sun, but the sun revolved around the Earth. Having said that, the most commonly accepted system at the time was the Ptolemaic system which is the one shown in the video.

I love your style. You don't dumb down the concepts but instead find ways of communicating the concepts that are accessible. It is a pleasure to learn this history from you.

The world is awaiting for the next part with a lot of expectations. Please publish it asap.

Fantastic videos! I'm looking forward to the rest of this series.

I have never watched a long video for more than 3 min ... And that too with time Waiting for your next video in This is Awesome 💖💖💖💖💖💖

[timshel]

Thank you!!! Wish I had this videos in highschool. Looking forward to your next explanations!

[infinitelove]

Such a great video ❤ deserves an award 👏

The first person to discover the heliocentric system was the Greek Aristarchus of Samos in the 3rd century BC. Copernicus and Galileo were 2, 000 years after Aristarchus

Why did you stop making the videos? You will fulfill your goal of 100, 000 viewership only with persistence and consistency. You have already taken the first steps to climb the mountain; please keep climbing. I assume it took you many hours of persistence and consistent practices to achieve your command on mathematics. The same goes for your success in YouTube viewership.

I found the history of natural logarithm video, binge-watched the calculus ones and now i find out you just released the 3rd! Please keep making this series, looking forward to it :)

[asif]

I hope this channel grows and you continue to release more fascinating videos. Absolutely amazing content
Thank you.

I wish you were my math teacher when I was young. I hope you will have the passion, the motivation and the discipline to continue making these videos.

[anatoliikryvorig]

Man your seria is absolutely brilliant. Please continue to do this. I can’t wait to see the next video!

[johnlennon]

Holy shit, I dont remember when I have felt such an enlightenment and clarity after watching any math videos here. This series is so good, its like made from future, when they finally got how to teach properly. The design is also amazing. The author is definitely one of high souls living on planet our time. Thanks, and I wish you all the best!

[gametimewitharyan]

I cannot expess how masterfully you explain each concept, and the history series is just so good, keep up the good work 💯

[dathkakashi]

Great and understable video. Really like this series of the history of calculus and videos about the history of mathematics in general. Looking forward to your next video and I'm really glad that I discovered your channel a while ago.

[tanvirahmed]

Such a magnificent work.!
Thanks a lot ❤

[mrshodz]

Could you possibly do a video how Hindu Mathematician worked out the series for Sine, Tan, Cosine and the Taylor series and infinite series for calculating areas under curves from a historical perspective please.

[gokulkrishnans]

If people like you taught maths people would never hate maths. Iam a physics graduate. I really adore and enjoy the beauty of mathematics. But some times i do feel exhausted by the amount i have to study. But videos like this reminds me, why i study this subject. It reigintes that passion i have for studying. Thank you for sharing this. Please continue the series. We are waiting.❤

[moularaoul]

Thank you for your outstanding work! This is a wonderful share!

You are an amazing orator. Every statement said is a bullet of information, dense and precise.
