Prologue to Calculus (1 of 5: How fast did Usain Bolt run?)

[Physically_tired]

“We don’t think in metres and seconds generally” *offended in physics*

[grahamkerr]

This is the best lesson on the basics of differentiating I’ve seen across the internet and in textbooks. A godsend 🙏

[marcushendriksen]

Great video! I am however a little saddened by the missed pun in the title. It should have been "How fast did Usain bolt?"

[sgdukerable]

You are a fantastic teacher, thank you for doing what you do. I hope you never lose the inspiration to teach

His acceleration comes when he was fully upright. Shoulders are square with his hips, which make his kicks propel him faster than anyone in that race.

[ashwin]

That was just his average speed, his peak speed was 40+ kmph. And if he wanted to make a record he would have run faster instead of celebrating before reaching the finish line

[bobtivnan]

I'm guessing Eddie has read Steven Strogatz's new book Infinite Powers. He uses the same example to introduce calculus.

[qualquan]

Differentiation is basically finding the Individual Components (IC) of the Whole and not restricted to finding the velocity.
Integration is finding the Whole given the ICs and not restricted to finding the Area.
So its all about ICs and the Whole and not just speed and areas.

I don't know which class your teaching but we learnt these conversion in primary school .And we are expected to do those all calculation in just one step.
By the way your teaching skills are just awesome

[mugyenyiedward]

Thank you l think you are just talented because there are some concepts in that were difficult for me to understand but when i watched your videos they are now so easy

[abhishekpariyar]

This is for the commentator in the Usain Bolt video, it ain't easy mate.

I am from india your vedios are awsome sir ..✌️✌️

[architad.]

He simplifies it so much we Indians can never find a teacher like him 😭

Correct answer for 100m/9.58 seconds will be 37.57Km/h
150m/8.70seconds will be 62.06km/h

[jayden]

And to think his overall top speed would be higher than that cause of course your dealing with averages in this case. Which is why it's good that you point out that his 150m race gave him a faster 100m time. Think it would give people an insight behind the magic of numbers I feel.

1:04 THAT 9.69 THAT 69 AKA JEN'S CONSTANT NICE.

[ksrinivas]

Thanks for the Video .. I will change my name to Eddie Woo😍😍🙏👨‍🚀👨‍🔬

[alert]

I am from pakistan
You make me to love with math

[avi]

Eddie, be careful to not get this video demonetized

[mccalliechinese]

Interesting fact. 10m/s. 10 meters is it's about five times as long as a Twin Size bed!!!
