Maths, but not as you know it…
Each year one quarter of the UK population buys a new Christmas jumper, despite a third of the UK already owning one, which made me think – what impact does this have on the environment?

Following the Deepwater Horizon oil spill in 2010, scientists at the University of Cambridge have been studying underwater plumes to try to understand how the Earth’s rotation affects the spread of oil. Their experiments revealed the important role played by conservation of angular momentum after one rotation period, emphasising the importance of a rapid response to a disaster.

Dr Tom Crawford joined the Hall in October 2018 as a Stipendiary Lecturer in Mathematics, but he is far from your usual mathematician…
Tom’s research investigates where river water goes when it enters the ocean. A simple question, you might first think, but the complexity of the interaction between the lighter freshwater and the heavier saltwater, mixed together by the tides and wind, and pushed ‘right’ along the coast due to the Earth’s rotation, is anything but. The motivation for understanding this process comes from recent attempts to clean-up our oceans. Rivers are the main source of pollution in the ocean, and therefore by understanding where freshwater ends up in the ocean, we can identify the area’s most susceptible to pollution and mitigate for its effects accordingly.
To better understand this process, Tom conducts experiments in the lab and has conducted fieldwork expeditions to places as far-flung as Antarctica. What the southern-most continent lacks in rivers, it makes up for in meltwater from its plethora of ice sheets. The ultimate process is the same – lighter freshwater being discharged into a heavier saltwater ocean – and as the most remote location on Earth the influence of humans is at its least.
If you thought that a mathematician performing experiments and taking part in fieldwork expeditions was unusual, then you haven’t seen anything yet. Tom is also very active in outreach and public engagement as the author of the award-winning website tomrocksmaths.com which looks to entertain, excite and educate about all thing’s maths. The key approach to Tom’s work is to make entertaining content that people want to engage with, without necessarily having an active interest in maths. Questions such as ‘how many ping-pong balls would it take to raise the Titanic from the ocean floor?’ and ‘what is the blast radius of an atomic bomb?’ peak your attention and curiosity meaning you have no choice but to click to find out the answer!
Tom is also the creator of the ‘Funbers’ series which was broadcast on BBC Radio throughout 2018 telling you the ‘fun facts you didn’t realise you’ve secretly always wanted to know’ about a different number every week. From the beauty of the ‘Golden Ratio’ to the world’s unluckiest number (is it really 13?) via the murderous tale of ‘Pythagoras’ Constant’, Funbers is a source of endless entertainment for all ages and mathematical abilities alike.
And now for the big finale. If you are familiar with Tom’s work, you may know where we are heading with this, but if not, strap yourself in for the big reveal. Dr Tom Crawford is the man behind the ‘Naked Mathematician’ (yes you did read that correctly). To try to show that maths isn’t as serious as many people believe, to try to engage a new audience with the subject, and just to have fun, Tom regularly gives maths talks in his underwear! His ‘Equations Stripped’ series on YouTube has reached 250,000 views – that’s a quarter of a million people that have engaged with maths that may otherwise have never done so. His recent tour of UK universities saw several thousand students come to a maths lecture of their own accord to learn about fluid dynamics. It may not be to everyone’s tastes, but our current methods of trying to engage people with maths are failing, so why not try something new? This is maths, but not as you know it.
You can find all of Tom’s work on his award-winning website and you can follow him on Facebook, Twitter, YouTube and Instagram @tomrocksmaths for the latest updates.

Current underwater vehicles are rigid in structure which limits their suitability for many tasks required for ocean exploration. Francesco Giorgio-Serchi is working with a team at the University of Southampton to design new robots based on squids and octopuses that are made entirely from silicone. They are not only more mobile, but are also more reliable and more efficient.

Pollen is the main source of protein in a honey bees diet and so it’s essential that they are able to carry enough of it safely back to the hive. Marguerite Matherne at the Georgia Institute of Technology studies how they use nectar to create a viscous suspension that sticks the pollen to their hind legs and ensures that it doesn’t fall off during flight.

The air density on Mars is 1/100th of that on Earth which means that current airborne vehicles cannot be used to explore the planet. Jeremy Pohly, at the University of Alabama Huntsville, is designing new bio-inspired vehicles – based on bumblebees – which he hopes will be used in the near future for the human exploration of Mars.

By improving our understanding of turbulent flow over canopies we can design better cities to improve air quality – just one of the applications of the work of Alfredo Pinelli, a professor at City University of London working on Large Eddy Simulations (LES) of turbulence.

Another fun-filled hour of your favourite two things – maths and rock music – courtesy of Tom Rocks Maths on Oxide Radio. This week I’m joined by two of my students from Teddy Hall, Fran and Tom, who will be explaining their favourite mathematical topics, taking part in a bumper numbers quiz, and sharing some of their music tastes. Plus, the usual dose of Funbers, and excellent music from Panic at the Disco, Sum 41 and Muse.
With thanks to Alice Taylor for production assistance.
