Have you heard of Heron's Formula?
So I got thinking about this after I had helped a tutee of mine with a geometry problem. As I had expected, there was a formula that calculated the area of a triangle from the length of its sides alone: Heron's formula. It's understandable why we don't focus heavily on this formula, but it doesn't change the fact that it's a neat looking formula.

How did Archimedes ACTUALLY calculate pi? Pi day 2021
มุมมอง 3.5K3 ปีที่แล้ว
#piday So this fella, Archimedes, in 250BCE bounded the value of pi to incredible accuracy. That's only 2200 years ago or thereabouts. So how the heck did he do it? Well for pi day 2021, that's what we're going to be diving into in this video. Enjoy! Here's my post on the angle bisector theorem: pB-WzBspFJvD/ Here's a few of my sources I used for the video: Euclid's elements webs...
Logarithms: why do they even exist?
มุมมอง 97K3 ปีที่แล้ว
Hi guys! In this video I chat about the history of logarithms. I know... not the most exciting topic but it turns out they were pretty influential in mathematical history. Enjoy! Hannah Fry hosted a great video on Numberphile talking about Weber's Law.

Climbing falls make no sense! Exploring the physics of climbing falls.
มุมมอง 1.2K3 ปีที่แล้ว
#climbing #fallfactor #physics Oh hey there! In this video I discuss the physics of climbing falls. They seem to be so counter intuitive. For instance, as I discuss in the video, a total fall of 10m with a rope length of 5m produces the same impact force on the climber as a total fall of 4m with a rope length of 2m. How bizarre!? Surely the greater fall would produce a greater force, no? Well e...
Engineering graduate gives 4 study tips for Engineering students
มุมมอง 3923 ปีที่แล้ว
#studying #studytips #engineering Hi folks! Happy New Year to you! This video is for all those students that don't see studying as something to look forward to... so the majority, I can imagine. I focus not on the typical studying tips you see experts talk about, but on my own discoveries of what's important to try and strive for when taking on a study session. I've wanted to do these kind of c...
What is Exponential Growth Bias? And are we guilty of it?
มุมมอง 4654 ปีที่แล้ว
#exponentialgrowth #COVID19 Exponential Growth as a term has been used left, right and centre over the passed couple of months. But how many of us can really grasp what it means? And when we try, do we fall prey to exponential growth bias?

How to find Eigenvectors and Eigenvalues. And what would make us look for them in the first place?
มุมมอง 6994 ปีที่แล้ว
So the common question is, "what are eigenvectors and eigenvalues?" but I find the best question to ask is "what would make us look for them in the first place?". In this video we discuss just that. It's no good to just show the eigenvectors of a matrix transformation. Instead, I like to allow us to realise why we'd believe they existed at all. Once believed to exist, we can then ask where the ...
What is an Inverse Matrix and how can we use it to solve simultaneous equations?
มุมมอง 3504 ปีที่แล้ว
What is an Inverse Matrix? Now I used to answer that knowing only how to use an inverse matrix when solving simultaneous equations. If you were to ask me why it helped us solve them regarding the space it was acting upon, I'd have to shrug my shoulders and probably just regurgitate what I'd just said. This video is all about answering that question. What IS an Inverse Matrix? If you haven't see...

I made a medieval BALLISTA!
มุมมอง 1.9K4 ปีที่แล้ว
Yep, I made a ballista. This medieval machine fascinates the mechanical engineer in me. So I couldn't help but take it on as a project! I'll be doing follow up videos on it in the coming weeks. Discussing some of the decisions behind the design, the good, the bad and the laughable; with the aim of learning what went well and what didn't. And I'll also be diving into some mathematical research I...

Hey seem obsolete.. Like trig tables
Outstanding! Thanks mate! :)
You're welcome pal
08:25 I feel like some example would be nice, I am not sure if I understood how they could calculate any numbers. But so far the video is very interesting!
exactly! I was missing that too
th-cam.com/video/e7DAM1zFDec/w-d-xo.htmlsi=XRLgfy9BfyMHvkUk, this is much clearer, than yours
You are rambling imo. I still dont know what logs are. I must be stupid.
Great video! thx
Logarithms = slide rules. they owned the 60s.
I wish this explanation was given in my secondary school maths class without having the log tables given to you like some sort of book of magic spells!! 😢
why are logarithms hated?

Please make a video that explains why suddenly google popped up your content as a suggestion.... to which I have now subscribed.

Great one !
I wrote a Visual Basic function capable of taking logarithms in either base 10 or base e. It used square roots and was surprisingly short. (I also wrote an inverse function to extract numbers from their logs in either base.)
One of the reasons I didn’t do ‘A level’ maths. I wanted to like maths but couldn’t.
Wow 👌
Topness abounds. The enthusiasm for the history and the application is very
Thank you so much. What are they good for. This is my frist question
Hi Congratulations from the French Alps. I love your story telling about logarithmes. I had two challenges while watching your video. The language and the maths. I am getting better at both because of you. Not kidding. Keep on doing videos of such quality. All the best cheers. third challenge was typing in English.
So interesting!
Solid advice, have already been implementing some of these.
Simply amazing! High quality and high effort video with a great explanation, thanks!
Thanks pal! Really appreciate the kind words.
What error was introduced in the square root of 3 that Archimedes used? How much did that error affect the calculation of pi? Nice video, alas, fast tempo:)
Not only are you incredibly knowledgeable and engaging you are also funny, charismatic and an incredible story seller communicator. Bravo! Subbed!
I have watched this video like... 10 times already. Trying to understand each step. Thank you Very much
Hi sir✋. Great teacher Thank you sir
Every log video on youtube just adds to my limited understanding. This was excellent.
Great work❤
Why did you stop? Your content is beautiful, you must go on
think this damn thing has gone in now! I had to pause it on your final picture with all the available choices, stare at it, then cross reference it with a reply you gave to someone. By far the best explanation for me, well done...

This video deserves way more views. Ever thought about designing a ballista with vertical arm? Been wanting to make one
This is great. It didn't fully click when watching other videos. I understood how it works, but I didn't understand why was it created in the first place and its application.
