Haha i love engineers
3 years into my Math degree, and I still find elegant explanations of calculus to be highly fascinating. Calculus is the reason I pursued math in the first place.
In the fourth year you will learn that for mathematicians, the actual solution is not interesting, only the fact that a class of equation has a solution 😁
@@arctic_haze Agreed , example Finding the integral makes total sense when you reverse the derivative and increase the exponent by 1 , because that gives the total area. However the denominator(which divides the total area to give you the area under the graph) you must arrive at is a rule that you just have to accept no explanation as to why areas work like this but it's just a fact. I know it works like that in order to get back to the derivative but how it arrives at the area is a rule you have to accept.
Interesting or not
Especially when the "explanation" smiles and jingles at you like you're the one!
I explained to my daughter when she was in late high school that calculus was all about slicing...lots of 'slicing' into lots of 'slices'
"Where are you going with this, Zeno?"
Not to the end, that's for sure
"And that's why it is impossible for me to get up to take out the garbage!"
@Roger Loquitur Zeno is often thought to be a student and proponent of Parmenides, rather than Empedocles. (that "ardent soul who leapt into Etna and was roasted whole") Parmenides is often thought to have argued that change is impossible; Zeno seems to be giving examples in his paradoxes of why change is impossible.
But it's hard to know exactly what Parmenides argued for two reasons: 1) Half his book is missing. The Way of Truth survives, wherein Aurora, goddess of the dawn, gives him divine knowledge of the true nature of things, but the other half, The Way of Seeming, is lost. And 2) his Greek is obscure (I am told - I don't read Greek) and difficult to understand even for those who are fluent in the ancient language. He pronounces that "Is is; and is not is not" - often translated as "Being is, and Non-Being is not." But that's not crystal clear. One author has suggested it's a description of Euclidian space: there are no voids in Euclidian space that the compass and straight edge can't traverse, no "is not" in the geometric plane or volume. Likewise it cannot be altered. You can move your desk across the room, but you cannot move the place your desk used to be. You can't alter it at all. But there are other interpretations, and the most common is that he argued that change is impossible because change involves something that is not being but rather "becoming," somewhat friendlier to the objections in Zeno's paradoxes.

@@eyeballs50 Your toenail or your shoe or whatever is foremost will always be on the beginning of a new gap, just like when runners do the 100m dash when they in position to start their fingers are positioned before the white line.
I use a lot of these maths principles weekly and you explained it better than my lecturers ever did! Even though I know this stuff it's fun to hear it explained so well and in a fun and engaging way!
Would you then hunt deers or photograph geeses?
@@allenalsop6032 Do you think the singular of mathematics is mathematic? Or physics, physic?
1:50 - Xenos paradox is much better represented by saying before you can first travel that half, you must travel half of that.This variant has you never even starting to move, as it shrinks backwards to zero infinitely.
That is a brilliant point. Using Zeno's own logic, one could never take a step.
@@carlsanders7824 Perhaps that's why he called movement an illusion?
Well, since both representations apply to arbitrary lengths including everything approaching zero, they are basically the same - at least at the limit… 😉
Which, is, I think, a tautology.
How can you move half the distance that is smaller than the distance taken up by your mass?
You can’t. The paradox doesn’t make sense in a quantum world where mass takes up a discrete amount of space.
So no paradox - just a poorly defined mathematical approximation of the physical world.
I remember thinking about Zeno's paradox in undergrad and it made me think that the fact that we can move around at all is because the infinite sum 1/2^n converges.
Well, that and friction.
"Calculus" was the word used for any systematic method of calculating. Newton speaks of "an arithmetical calculus" being used by Dr Halley to do a better calculation of the orbit of Halley's comet than he himself could do by geometrical means using very large sheets of paper. The calculus you're speaking of was really called the "Infinitesimal Calculus".
The little Roman stones (calculi) were used as counters, not to divide big things into lots of little things.
"Infinitesimal Calculus of a Single Variable " to be more precise. Many different types of Calculus exist ie., Calculus of Variations, Vector Calculus, Complex Calculus etc.
Wonderful explanations. I also liked how at 4:20 an emergency siren is heard approaching (but never quite arriving) at the filming location; it had its limit.
also at 6:25 ^^
Im so happy the animations are back. 🤗
but Zeno is looking a little mad haha, I wouldn't trust a man looking like that either.

I wish I could have watched this before I learnt calculus. It would have been super useful!
The now version of integza knows a bunch of cool things to use calculus for!
yeah the 5 months ago version of me would also find this more useful
Love your work integza
The Engineer in me appreciates it even less after 2 years of math.
Zeno's paradox is easily resolved when you remember that movement involves time as well as distance. The statement "you never reach the end" has an implicit assumption of the existence of a time dimension.
well it seems like a simple X,Y graph showing distance and velocity. tending to Zero ,,but not getting there,
@@whoarethebrainpigs because you are implicitly slowing time down to a halt
Okay, let's say it takes you 2 hours to travel from point A to point B, an hour to travel to reach a halfway point between them, and so on as with a "travel distance" example. This paradox works both with space and time.
@@FerunaLutelou Imagine recording a video of a person walking from point A to point B, and then playing back the first 1/2, then the next 1/4, then the next 1/8, etc. We'll never reach the end because of the endless pauses between playbacks, but we could just watch it all in one go with no pauses. This doesn't seem paradoxical to me at all, it's just saying endless pauses never end, a tautology.
@@joebloggsgogglebox there are no real "pauses" in this problem. Really bad example.
I love that you're so passionate and determined to teach me something that you totally ignore the sirens in the background. Awesome work. New subscriber!

Thank you! I have been learning neural networks and was so happy to see you explain the derivative so clearly.
for every step, you are moving through an infinite number of half steps, which is a subset of the bigger infinity that is the total distance you will walk, therefore, you are definitely moving and not just frozen at any point.

I kid you not. Years ago I performed in a play by Aristophanes. It's a Greek anti-War play "Lysistrada" and the men are involved in the Peloponnesian war. The women decide that withholding sex will bring them home and end the war. Since the men could not actually set fire on the stage and we (the females) had seized the Acropolis... How you ask? Nerf guns. Just like you see here. The men had Nerf guns too. It wasn't 411 B.C.E. but it was the 1990's and not taken out of period. I was a scientist before and after a few years returned to my roots. Nerf guns are educational; math and literature.
Finally, after decades, someone explains this in a clear, simple and great way! Thank you!
Same here. I scored a B in 4 courses of Calculus and then a B in differential equations. I could solve the problems but never understood why calculus works.
I lay golf so I used calculus to figure the angle the ball must take from the tee for maximum distance. It is 45 degrees which seems intuitive. However, you font know unto you know.
There’s is a highly successful pro golfer that says all his success is based on physics and math ( don’t know his name because I never watch pro anything.
This is one of the best description of the basic principals of Calculus I have seen. Since it is a public video, I am sharing it with my students. Thank you.
It’s wonderful how excited she gets when she imagines we get the right answer to her questions. Limits!
It's like we are babies and we actually slid onto the pot before we ...said anything stupid. LOL
Yes, I love being treated like a child..
An engineer, a physicist, and a mathematician are at a bar and see a beautiful woman across the room. They're all too nervous to talk to her so the physicist devises a plan to work up the necessary courage. Walk half the distance from them to her, then half the remaining distance, and again, and again, and again. The mathematician says it won't work because they will never actually get to her. The engineer says, "Well, it's close enough for practical purposes."
😂😂😂😂😂
A physicist, a biologist and a mathematician were in a bar, looking at the empty house across the street. After a short while, a man and a woman enter the house, coming out an hour later with a baby.
The physicist comments: "The house can't have been empty from the beginning!"
The biologist replies: "They must have reproduced!"
The mathematician states the obvious: "If exactly one person enters the house, it will be empty again!"
Just discovered this awesome channel, so lucid content that I had to subscribe right away. Keep up the good work.
As a life-long lover of calculus who sometimes had trouble grasping the central themes, you were able to help me visualize why integrals, derivatives and the limit actually work together to actively solve the problems I could arrive at the answer to, but not understand in an intuitive sense why it worked or the underlying logic. Thank you thank you thank you, you have re-ignited my love and admiration for mathematics!

Great job! Finally a good 5th grade level explanation of calculus I can show my nephews!
you need more subscribers!! your videos are always so fun to watch!
I have to say, the passion with which you talk about mathematics is truly remarkable. You obviously don't simply know what you are talking about, you love it, and that is the mark of the true professional. It's a rare trait in people who teach for a living, and considerably rarer in people who teach math. You've definitely earned my like and my subscription. Kudos!
Also, after watching so many science and tech videos on UA-cam that advertise Curiosity Stream and Nebula, you were the first presenter who made me interested in actually checking them out.
As an engineer, I have to say that I love the way you talk.
Usually when people explain this things, they do it with serious and deep voices, which subconsciously makes people think that this are serious, deep and difficult topics.
You on the other hand, explain this things in such a cheerful and happy manner, that it makes me feel that this are cheerful topics, that we should be happy learning about this things.
Please don't change!!!!!!!!
75 yr old engineer has that same curse. "gotta make it better."
"these".
Hey but calculus (and math and physics and cosmology and chemistry) ARE all cheerful and wonderfully interesting topics! My mom introduced me to these ideas when I was just a 3 year old toddler and I kept asking about concepts like infinity as it was so hard to wrap my head around it. I still feel the same wonder now 45 years later.
oh, brother, I cant tell you how hard I laugh reading ur comments though it make sense
Yes!
Up and Atom: "I couldn't find a bow and arrow so I am using a nerf gun instead."

I think they were going a little too PC. It is a lot easier and safer to tape a Nerf gun, too.
"modern" problems? o.O
Disclaimer. It's been over 45 years since I had my calculus classes.. BUT this is the best and most concise introduction to the subject that I've ever seen. It brings together the great "philosophical" (at the time) blockbuster of Zeno's paradox with modern mathematical tools AND keeps showing how the idea of a limit is a tool used in all of these. GENIUS!! It's like turning math into LEGO bricks! I know someone who definitely doesn't know higher maths and will be trying this out on them.
Great attitude but calculus is still in the realm of elementary math. And unless you say things like "5 deers and 8 geeses and 4 mices....math is already both singular and plural. "Maths", was just a mistake someone made that caught on with those who didn't know any better and then spread to others of the same ilk.
@@allenalsop6032 Starting a reply with a condescending remark? Check. Going on to nitpick a trivial "mistake" (it's not) that makes no difference to anything whatsoever? Check. What a sad person you must be.
Very well built up explanation of calculus paradoxes, nice video animation and a enthousiast and inspiring presentation. Wonderful.
Your enthusiasm and ways of presenting challenges is heart warming and makes me reconsider my math phobia :-D
I really wish I saw this before taking cal 1 and 2. You explained the real-life implications behind the mathematics so much better than my professors. Makes it a lot easier to grasp what exactly we are calculating in real-life. Well done!
You are doing great for sure keep you the amazing work I hope your working on these paradox’s yourself the more people who are trying to understand it the better chance we have at coming to an understanding
Years of university maths and I never fully grasped what I was calculating. Thank you for giving real life examples and making this super simple to understand!

This is amazing! I love this video. This is perfect for someone to see as an intro to Calculus.
Great introduction to Calculus! Definitely worth showing to prospective math students.
In 1969 my Calculus teacher taught us Xenos paradox by describing the erasing of the black board, which always could be halved.
This is the _best_ summary of what calculus is that I’ve seen so far. Thank you!
This would have been so helpful while trying to wrap my head around calculus in school. Limits are one of those things that make no sense up until the moment it clicks. Then you look back and can't understand how you couldn't understand it before.
I was thinking how useful watching a few hours of instruction in this format from different personalities (especially hers) would have helped me in school.
Awesome “why” video. Whenever teaching, I always think students aren’t given enough “but why am I learning this”. And sirens made me look out my window! Twice!
I don't know why no one else is talking about the sirens..I wonder if they were on purpose or just happen to be going by while she was filming
And I just then realized why sirens are called that. It's because they distract you from your goals!
Once you reached the first 1/2 Stade mark, you've already traveled an infinite number of fractional stades to get there.

When I heard Zeno's paradox for the first time as a child, my first thought was: That's silly. He's looking at increasingly smaler times. So all he's saying is: When time stands still there is no movement.
I was thinking he could easily solve it by setting the mathematical finish line beyond the actual finish line.
Very well presented. Good job!

I'm more than a bit dyslexic, and every time I see this, I go back to how I did it in high school, putting triangles in the curves, and doing the individual area from them, and arguing with the teacher I got a more accurate total. I always lost, but always got the steel to the right shape and size. I make sense of it in my head, it's rational, logical, I get lost twisting the numbers, doing it. Very well demonstrated, and with Greek, that I saw at about five, in Greece. Thanks very much.
Seriously Jade. I love your education ways
Great video!! Infinity is cool 😁
Also, I meant to say that my favorite drawing is the one on the left 😋#Entropy
ah, mr. laplace/bayes :D
Very well explained. Well done. Let me consider the first paradox covered, Zeno's.
The fault with Zeno's logic is that he assumes all we move is 1/2 of one segment each time, stopping at each 1/2 segment. If we did that, then of course we would never reach the end, because we would be shortening our step each time. Toward the end, our paces would shrink down to 1 cm per step, then the next step would be 0.5 cm, then our next step would be 0.25 cm, etc. If we did that (shorten our step to cover just 1/2 of the remaining distance), then yes, we would never reach the finish line.
But in reality, we do not keep shrinking our steps by 1/2 each step we take. We simply take as many steps as we need to cover the total distance. When we add up the distance of each step, we end up covering the entire distance to the line and even cross over it. Why do we reach the finish line? Because the sum of the lengths of all steps equal more than the distance to the finish line. We are not shrinking our steps and stopping at each 1/2 point.
But why is Zeno even proposing this? He presents a ridiculous problem. Ultimately, all he is saying is, "If you reduce your stride by 1/2 each step of the way, you will never reach the finish line." We would then say to Zeno, "Of course, you weirdo. But why would you reduce your stride by 1/2 each step of the way?"
In truth, we reach the finish line every time because we don't reduce our strides by 1/2 each step of the way. We simply add up the distance of each stride, and after enough steps we surpass the distance to the finish line and cross over it. To Zeno I say, "Zeno, motion is no illusion. Your sense of superior intellect is."
Sums up as: the greater the number of steps 👣tending to infinite, the smaller the error tending to zero 0️⃣.
I love your videos. Highlights to my mornings and coffee TY!
Actually Jade this is The Best Video On You Tube ive Enjoyed So Much ❤️❤️
I would have been so much inspired to study if I would have seen this video as a teenager! Not that I didn’t end up taking science as a career..but your way of explaining is just mind boggling dear.. Love❤️ your work and hope that all the teens aspiring to take up science or engineering watch your videos first 👍🏻
It would have been so much better in school if I had a teacher as enthused about the subject as this young lady is..
Oh my god. You're the first person that made it click for me!! Now I actually want to go learn how to do some of this!
3Blue1Brown also explains Calculus.
Very very good! Absolutely relevant knowledge, absolutely well explained! Many thanks!
Awesome video, keep up the good work!
how about this: the smaller the steps get, the faster you traverse them. so, you become infinitely fast and can get to the end of infinity this way in finite time.
Yes, if you halve the steps, you halve the time taken to make those steps, and the infinite sum of those times converges to the time taken to cover the full distance. Since time moves at a constant rate, you cover the distance in the time equivalent to the infinite sum of times taken to cover all half segments. If it took the same time to traverse each half segment i.e. your speed halved each time, it would take infinitely long to traverse the distance. The point is the paradox would be complex to get your head around if the concept of mathematical limits has not yet been established.
@@darbyl3872 The animator apparently suspects this. 🤪
@@darbyl3872 yet you can't explain it without needing a "definition fix".
Let's see you explain it in those terms in order to get to the Truth.
That's the issue.
Logic can't get you there, approximations must be made. Hence, the birth of conventions *instead* of truth.
And no, your speed doesn't change if how you divide space changes.
Proportions however...
(Your foot would be 10ⁿ compared to the miniscule divisions)
But your foot would also be divisable...
Again, the confusion comes from the half-baked portrayal of the philosophical thought.
Zeno's aim is to say: everything is one. (That's his main premise/theory.)
Division, happenings, etc, are therefore just facets of the whole. Taken in isolation, they produce paradoxes, are distractions if you wish.
A more crafty, statistical, scientific way to say this is to say scale and dimensionality of interactions matters.
Studying x in isolation from the rest, yields a considerably different model than what we observe in nature.
The reason Zeno's paradox does not work is firstly, because we are not moving half-way to any given point, we are moving towards the point and as we are, we are walking past arbitrary points between our original point and our destination. While Zeno points out we move through the 1/2 and 1/4 points, we are also moving through the 1/3th and 1/6th points. Does the fact that we now account for walking through all of the 1/3x points now increase the destination we travelled?
So the first thing he does is redefine movement using arbitrary points. But lets grant him this, but rephrase it as the turtle in a room moving from one side to the other in this manner. It would take it infinity steps to reach the other side, if we ignore that the turtle has a length itself. If we place the movement at the furthest point back to see how far he needs to travel, then the turtle will only need as many steps to reduce the distance to the further wall to being less than its own length. If the marker if half-way up the turtle, then it needs to travel until the distance is half its length. And if you want to get the marker as far up one on the turtle as possible, then you run into a zeno's paradox within a zeno's paradox.
Zeno's paradox raises interesting questions about infinity that can be explored mathematically, but do not raise interesting questions about reality because it one preposes that objects don't have length and that there isn't any interesting in saying that if you walk X units, you have also walked 1/3 + 1/3 + 1/3 units, which is what he is effectively saying but making the expanded form of X infinitely long.
Why can’t I like this video twice??? 😭
It’s so good!

Jade, spot on terrific way of describing Calculus. Although it has been years since I was in school learning about advanced math, it seems like only yesterday I was using Integration and Derivatives to solve problems. It has helped me better understand many things outside of math in everyday life too.
You explained the basic concepts of calculus in a way that finally clicked for me. Great video
I've been waiting for ages now jade. But ur vids r worth the wait hehe😄😄😁😁
Yay! Thank you!
@@upandatom You deserve it! 😊
At some point, the remaining distance is one Planck length, and you must then traverse that one Planck length.
technically we don't know if the plank length is the smallest length overall all we know is that it is the length where the Standard Model and GR break down
And in 99.99999999999999999% of all the circumstances you may ever need to measure, this will never come into play and is just an academic exercise.
An Engineer will look at this and say, "Do I need that much precision? No? Then we've arrived. Next problem."
I wish I had a good teacher like this. Your explanations are so clear
In school this year we learn integrals, and last year started derivatives, and no teacher could explain those concepts better than you. Thanks

Wait, no. "Calculus" comes from the Latin word for "small stone" ( _calculus_ , _-i_ ) because small stones were the most elementary object used as an abacus in ancient times. Or at least so we were taught in (Italian) high school! This is supported, for example, by the fact that in many romance languages a word directly derived from "calculus" is used to mean "computation" (Italian _calcolo_ , French _calcule_ , Spanish _cálculo_ , Romanian _calcul_ ).
The "breaking a big problem into smaller things" hypothesis for the etymology seems particularly weird to me, also given that the term "calculus" originates from the ancient Romans, not from the first users/inventors of infinitesimal analysis, centuries later. Or do you have some evidence for your guess?
- Anyway, you have a very lovely and enjoyable channel!
She's just shallow and quoting shallow references. Probably NPR.
As anyone can imagine, calculus as a word already existed. Actually, originally the field was called infinitesimal calculus, calculus for short nowadays, since we don't speak latin anymore and have the word calculation. Calculus just means calculations with infinitesimals.
It's not an etymological discussion. "Calculus" in modern times is used to refer to the branch of mathematics based on limits, including differential and integral calculus. What the word meant 2000 years ago is no more relevant to the discussion than the fact that the same word describes the crap the dentist scrapes off your teeth.
@@vampiresquid: yes but, if I remember well this video that I watched ten months ago, she was talking about the reasons why the word "calculus" is used to refer to infinitesimal analysis and she said "because it's a Latin word which means 'to break down into smaller pieces' " . But that's not the meaning, so...
Excellent descrbe. Thank you very much sir.
You are good. Thank you and happy new year
Zeno's mistake, of course, was that *steps* *don't* *work* *that* *way*
even so, he changed everything just by asking a simple question
What usually bothers me about this paradox isn't the steps, but the omission of time.
@@definesigint2823 I'm more fucked up that he doesn't seem to know how mass works.
@@noconaroubideaux9423 Do you? I'm pretty sure that humanity itself didn't even have an idea of what mass (i.e. the numerical measurement of a body's inertia) was until a rather short period of time before
Well, you move your foot, at some point in time it moves over all those halves and quarters etc, so they actually do work that way though?
@@iamtrash288 I don't mean mass in the sense physics describes. I mean that, eventually, if you keep breaking distance in half, your foot is gonna end up being at two of those different locations at the same time and it will continue to step on an expanding number of distances as those distances become smaller until it crosses the point of measurement.
The only way this thought experiment could work is if you were actually shrinking continuously with every step like a Mandelbrot Set to compensate for shrinking half distances.
My calculus professor boasted a 50% fail rate for his Calculus 101 class at my college. I was a Biology major and I barely passed, but I would have salvaged my GPA if I had seen this video back then. Math is fun when it is taught by someone who loves not only the content, but also the TEACHING aspect. You are a phenomenal teacher, and I’m glad I can still learn complex topics outside of school 😊
Very well presented. Keep it up.
Wow this is the clearest and most concise lesson on calculus I've ever seen!
You are so underated!
Or is she? 🧐
(She’s rated ∞)
7:45 right half of the rectangles should extend out
btw nice video
I noticed that, it was really bothering me, lol, but yes, also a wonderful video overall
That enthusiasm is so honestly cool
Wow, this is beautifully explained. The power of visualization is amazing.
As a high schooler that wants to be a physicist, this helped me A LOT.
Me too buddy.
Which grade are you in?
@@HHHHHH-kj1dg (Bad english) Last year, according to the educational system of Brazil. Converting, it’s probably 12th grade.
Just travel 2 stades and only go to the half way point. Take that Zeno
You do realize his argument also enjoys scaling the other way around, right?
His main argument could be reverted to before getting to the midpoint, you have to walk half way there
instead of the presented version of after walking half way there is still another mid point
.
The "before you get there" version is the one yielding the conclusion that you could never move anywhere presented in the video

Wonderful! Wish I had this available when I was in college-an indispensable supplement to a text book!!
Brilliant. Well done on a very coherent explanation. Thank you .
"Is math an invention, or discovery?"
Reminds me of the time an art history teacher tossed the "So.. what is art?" grenade into the class and sat back grinning while the shrapnel flew. :-)
Maths is Art, and Art is Maths ;)
alternatively what if it is all computation? Wolfram's model if true would suggest both arise from the same thing as any mathematical operation can be described in terms of computation. It is an interesting idea if we can ever get a mechanism to test it experimentally
@@archivist17 you mean math?
@@RockHudrock No. Lol.
@@Dragrath1 Some proofs aren't constructive, meaning there is no algorithm that gives you an answer through computable means. Thusly, math isn't all computation.
"Small, really small" - that's what she said 😥
i didnt need to be attacked like this today
And then she broke up with you by saying "I'm making a you-substitution."
Great description. Thanks
You are fantastic jade. Keep up the great work. I just love mathematics
I wish this video was out when I was learning infinite series in calc 2.
I will go in a wild guess here and say you didn't do so well in calc 1.
1:45
Damn
Zino looks possessed
Your way of explanation is very nice a actually you understood me calculus thanks jade.
9:40. Actually, the film is moving through the projector gate, the paper moves using the spring in the paper and the work done by your finger. Energy is imparted into both those examples of multiple still images
"I aspire to be her one day" YES! Hannay Fry is such an inspiration!!
This is why I love UA-cam 🔥
Thank you so much, this just changed my perspective for calculus, THANK YOU SO MUCH I HAVE NO WORDS!!
Had a calculus instructor in one of my Navy schools. He told us about the time he was required to integrate and equation. Instead of doing the math, he plotted the equation on paper and cut out the area under the curve. Then he weighed a ream of the paper and figured out the mass of a square inch of it. Then he put the cutout piece on a microgram scale and figured out its area. Handed in his answer which was closer than asked for and still failed on the question because he didn't do the math.
These days we have handheld calculators that will give you the answer in seconds.
I never took calculus but I was asked to calculate the surface area of a resin sculpture. so I filled a bucket of paint having weighed the the bucket and paint separately. Then I dipped the sculpture in the paint and let it dry doing so in a way that would result in even thickness of the coat of paint. then I measured the thickness of the paint. I subtracted what remained in the bucket from the total and the result was how much paint was on the sculpture. I measured the depth of the paint in 100 random spots and took the average depth and then using simple arithmetic I got an estimate for the total surface area of the sculpture. It took me a day to come up with my answer. An engineer then did the calculus using an engineering program and taking a lot of measurements but without the benefit modern high speed computers and took a week to get their answer. My answer was 0.00012% more than his answer. My boss then fired 1/3 of the engineers since that was mostly what they were hired to do and gave me a 50% raise and for the next three years I spent a lot of time dipping resin sculptures in paint.
