TEDx: Using Maths to Save Our Planet

By creating a mathematical model which identifies where pollution goes when it enters the ocean, we can stay one step ahead of the waste and help to save our planet. Dr Tom Crawford is a mathematician at the University of Oxford with a mission to make maths fun and accessible for all. In this talk, he discusses his research in the field of fluid dynamics, and how he has been able to construct a model which can predict where the pollution from any river, anywhere in the world will end up, using only three pieces of information widely available on the internet. For many people, mathematical formulae and calculations can be a source of anxiety, but Tom's experience and expertise will have you hanging on his every word from beginning to end, as he explains not only how we can use maths to save the planet, but how YOU can use the power of mathematical modelling to help to solve any problem you might encounter in your life.
Produced by Dr Tom Crawford at the University of Oxford. Tom is an Early-Career Teaching and Outreach Fellow at St Edmund Hall: www.seh.ox.ac.uk/people/tom-c...

[@Arkanorum98]

Hey, this was a great explanation of your work and made me want to read your actual PhD thesis. Is it available somewhere?

[@Harrykesh630]

12:40 now I know why you love Navier-Stokes so much !

[@Malak-kc9in]

Fantastic explanation of such an interesting and equally important idea. Very easy to understand..loved this!

[@rajasaurus3229]

I'll watch it!

[@linsteadar496]

Brilliant Tom

[@josephhernandez9098]

me gusta todo lo que haces en este canal, suerte y muchas gracias por compartir esto. Soy de Honduras y me meta es estudiar en Oxford, espero algún día ser tu estudiante.

[@AshutoshSingh07]

Thanks for uploading❤

[@jessicasmith7658]

Great lecture once again tom,
btw i might be completely wrong but i think i saw you as a flight attendent on my ryanair flight yesterday (as of writing this) coming from poland to london stansted,
i wasnt sure if it was you and it may just be someone similar to you and if so sorry for this very strange comment lol

[@D.Axtmann]

Watching it right now!😍

[@note9280]

Absolutely amazing explanation love it

[@benedwards7516]

I saw you give a talk similar to this at maths fest. Very interesting and well explained 👍.

[@drziggyabdelmalak1439]

Ignore the first 37% of those you date?! So, that's 37% of 1, then, for some of us!

[@bonky216]

At around 11:40 in the video you mentioned a current on the edge of your tank that represented the coast; That's the bottom edge of the tank in the videos perspective, right? So it seems that right-side edge on the northern hemisphere(and left-side edge of the mirrored southern hemisphere) flows along the equator? Is it correct that the pacific garbage patch is concentrated near the equator since the currents from both hemispheres flow through that direction? Very interesting video, thank you.

[@reoxoglephic603]

I think this might possibly be the first video I understand completely, possibly?

[@PMA_ReginaldBoscoG]

Waiting❤

[@sahlansidjara6838]

Brilliant

[@easyfundbles2608]

How it is so hilarious to know that everything can converted and transformed from real life to a mathematical models . Especially the last one one the modeled the love based on the theory of optimal stopping.❤❤❤

[@RpMcMurphy_]

Everything “in real life” can’t be transformed into mathematical models unfortunately.

[@cactuskiller3558]

How i can apply to oxford for the fourth and fifth year of a course in physics ?

[@DracoMhuuh]

OMG I was there. The lecture was absolutely fantastic!

[@ussr8410]

Bro but it is a live lecture 💀

[@DracoMhuuh]

@@ussr8410 it was back in April when I attended TEDxUHasselt

[@D.Axtmann]

🔥🔥🔥

[@signumscaler]

Amazing as always. I wish I was gifted towards mathematics but sadly I'm not.

[@ranjan924]

it's not a gift! simply practice and dedication to the craft should get you very far

[@comquatcash]

Let’s gooo

[@schulem1409]

Hi ,could someone please tell me:How can I become good at mental arithmetik? Are there any books related to that?

[@ethanpower4613]

Saw you give this talk with my college at some music university, icl the juggling guy was better

[@aventura1266]

I want to do math like you

[@Oneirophrenic123]

Hello Dr Tom Crawford! What is your favorite rock music? Please name a few genres, bands/artists and/or albums! I am a fellow rock enthusiast myself!

[@MariadeLourdesAniesSanch-ze7hf]

I guess
I have one for me

[@racquelsabesaje4562]

math

[@davcaslop]

USA, India, China and Russia actually agreeing on emiting less (way less) IS the solution. There's your model. 5 bucks please. C'mon, do we really have to make all of this to just arrive to the conclusion that we must see country by country how much each has produced to damage the environment and end up pointingh to the big 4 or 5 countries I just mentioned??????????

[@AhirZamanSairi]

Why focus on where the pollution goes, instead of where it comes from (people). Seems like a more direct approach to the root cause - unless you are looking for an alternative way to dispose of garbage than dumping to the ocean. If not, you somehow either make people put out less garbage, or garbage that's less harmful. There's no other way is there?

[@RpMcMurphy_]

Tom are you making the claim that CO2 is driving climate change?

[@davidc4408]

Mathematical modelling to solve any problem? To build a $1 billion investment portfolio from a $100k cash pile :)

[@abublahinocuckbloho4539]

too much lip smacking
