History of Calculus: Part 1 - Calculus in a Nutshell

[@sonnyobrien]

Wow, a real teacher

[@donjohnson24]

Oh! How I wish that this video had been my introduction to calculus when at school 70 years ago. I quickly learned the how of differentiation and integration, but the why of it eluded me for ages as we were told 'don't worry about that, it will come later'.

[@tareksaid81]

Thanks reza and I really like the analogy. I think picking up fruit directly from the tree is the most enjoyable way of having it and my goal with these videos is to help do the same but with ideas - seeing them directly from the source.

Thanks for your kind words and support tobias. I really appreciate it. And thanks for pointing out the time thing. At first I was feeling time pressure and wanted to publish something within a month of my first video. But it took away from the joy and passion for this project. So I decided to focus on that instead and take my time. Having said that, now that the story for whole series has been developed, I think the next videos in the series would be published a lot quicker

Dear Tarek, thank you so much for this video! Having Covid and after only lying on my couch for the past 4 days and binge-watching KZbin.... it is the first time I actually felt like there is a human being on KZbin who does not want the humanity to deteriorate.... appreciate your work! Please let me know if I can support your work in any way.

[@tareksaid81]

Thanks for your kind words and your support. I really appreciate it. Sharing it would be great as the KZbin algorithm would think it is worthy. Some people suggested that I start a patreon account but I thought it was too soon as I only have two videos. I am planning on starting one at one stage. Hope you feel better soon and here's a toast for uplifting humanity :)

[@emilyrln]

Top notch storytelling! Very excited to watch part 2 😊

[@nickxyzt]

This is a long comment. First, I would like to tell you that I arrived at your video by searching for "why do we study calculus", so it was by my need, not by a suggestion. I was so surprised to see you in another video! Second, I would like to tell you that I arrived at your video with logarithms also by searching (about a year ago), and I saw it at least 10 times (the same is true for this series). It's hard to find the proper words, but I think that you have something really special, and that is the desire to make the world a better place, the desire to make some order in the chaos (just to quote Aron Nimzovitch). Not just the simple desire, but a great satisfaction in doing it. I think that you have a great vocation to be an educator, and I strongly suggest that you should consider it seriously. My heart goes with you and all your friends and family who had to leave their home country because of the war.

[@tareksaid81]

This is an incredibly amazing comment and I really really appreciate it. I am lost for words as it deeply touched me as I felt heard and seen. From the bottom of my heart thank you and apologies about the late response. I have been off my channel for a while but now I am back on track :) I was thinking of pursuing an education role and now you have encouraged and inspired me to take action. Thanks for your thoughts about my country, I have taken a snapshot of your comment and shared it with family and friends from Syria and they send their regards. Thanks again for the deeply touching comment

[@horseloverfat6938]

I am hugely impressed by this presentation. It is invaluable for students or non-math geeks, and you have a real gift for communicating these concepts. The analogies and illustrations here are commendable for their clarity and incisiveness. You are definitely on the right track taking an historical perspective, and explaining so well right from the outset what Calculus "does". I love how you emphasise the critical role of curves in modelling all aspects of reality, and steer away from the abstractions of functions and limits in favor of visual geometry and intuitive ideas like infinitesimals. Understanding these was a breakthrough for me years ago in my own calculus journey. Your series promises to be a true service to math education. Bravo, sir! I just saw the second of your series has been uploaded, and realised I had not yet commented on the first. I wish you every success and I am only sorry I cannot support you more, being poor currently in both time and money - but I will spread the word and recommend you wherever I can.

[@tareksaid81]

Such a beautiful and supportive comment is worth more than any financial support. I really appreciate it. Thanks :) I struggled with the concepts of limits and functions when I was at school. I could solve problems, but I didn't know why we needed calculus at the time. Similar to you, it was a breakthrough moment for me when I got to understand calculus through infinitesimals. In fact, it made me appreciate limits more as only then I understood their true meaning. I believe that limits and functions can only be understood, or at least appreciated, after developing an understanding of calculus through infinitesimals and curves. Thanks again for your support. It means a lot

[@horseloverfat6938]

@@tareksaid81 I don't know what books you have been consulting for historical sources, but my favorite is one by Eli Maor, "e - The Story of a Number". It starts with compound interest and ends with Euler, by way of Logarithms and Calculus. It is only 200 pages but ranges from musical scales and harmonics to the philosophical implications of transcendental numbers whilst providing a clear explanation of what the Calculus of Liebniz and Newton "is" and "does". It is aimed at the educated reader and isn't beach-side holiday reading, but is still very accessible. Anyway, recommended - though I suspect it is out of print

[@rextransformation7418]

Fu*king hell, in less than 10 mins you've cleared up so much mental fog in my head bothering me since the early 2000s in uni class (and failing, but that's my ignorance)! Even looking at other math channels was such a challenging task, and I've asked for certain explanations (even to newly graduated students, kids of ex-colleagues) but received always the same repetitive answer. It's maddening because it seemed like they've memorized stuff without really understanding it; or because I'm too thick to understand, or they didn't know how to explain it. One thing tho I believe should have been said from the start in this video about curves in calculus (probably is in part two, but I've to still see it, will do after commenting) is that it's a visual aid for a function. Reminds me of a student in the same uni class who was puzzled in why there was a ball at the end of a semicircle (picture it starting from coordinates 0,0 curves upwards then finishes at π BUT with a circle, meaning it doesn't END there). The axis X and Y don't actually have to be perpendicular to each other, they could also be parallel, because the answer of the function will always be on Y axis, so there's actually a "hole" in the value π in axis Y, but to make things more visually better the axis are ⊥ to each other. However, TO ME this hasn't been fully explained in school (at least for what I recall, and again, the student in the uni class had the same erroneous idea) has made the initial idea of Y being the answer of any y= f(x)! Anyway, can't change the past, just glad to have found your channel. And now to part two. P.S.: THANK YOU for your channel!

[@tareksaid81]

I’m really glad the video was able to clear up that mental fog for you! I completely understand where you're coming from-it's so frustrating when you're trying to dig deeper into a concept like calculus and all you get are those same repetitive, memorised answers. I've been there too. I’ve found that looking into the history of these concepts really helps to have an intuitive understanding that often gets lost in modern teaching. Regarding your point about curves and functions, you’re absolutely right that curves could be considered as visual representations of functions today. Historically however, curves were studied long before the concept of functions was formalised. Functions actually evolved from the study of curves, which is why in the video I mention that 'calculus originated as a tool to study and analyse curves.' I’m really glad the video could help and thanks for sharing your thoughts

I have watched many videos on the calculus that I have found wanting in one or more respects. Poor production value is a big impediment for me when they put no effort into providing visual graphics beyond a white board where they scribble illegible ramblings of their improvised presentation. Another is lack of foundation where they write an equation to explain differentiation. Time out !“//“ I say. What the hell does that equation even mean and why would anyone feel the need to differentiate it? You seem to answer these failings of others who have thrown their hat into the KZbin education ring. I’m liking what I’ve seen thus far and look forward to contributing on patreon the impetus and support you need to produce and release the video series listed in your curriculum.

[@tareksaid81]

Thanks for your support, I really appreciate it and I will work on creating a patreon account soon. I totally agree regarding the need to understand what the equations mean before we work with them and this is the goal of this series.
