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.
I also want to say it's great to see there's over 200 of you subscribed to the channel! Thank you! I really do appreciate the support.

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

#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!

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...
