Aperiodicolleague Kit Yates has recently had a new book out: The Maths of Life and Death. He’s kindly agreed to share a sample chapter with us, explaining the God Equation: it’s used by NICE to decide whether to fund new drugs.
In my new book, The Maths of Life and Death, I explore the true stories of life-changing events in which the application (or misapplication) of mathematics has played a critical role: patients crippled by faulty genes and entrepreneurs bankrupt by faulty algorithms; innocent victims of miscarriages of justice and the unwitting victims of software glitches. I follow stories of investors who have lost fortunes and parents who have lost children, all because of mathematical misunderstanding. I wrestle with ethical dilemmas from screening to statistical subterfuge and examine pertinent societal issues such as political referenda, disease prevention, criminal justice and artificial intelligence. I aim to demonstrate that mathematics has something profound or significant to say on all of these subjects, and more.
We asked #bigmathoff competitor Lucy Rycroft-Smith to tell us a little about her latest project – CM Define It, an app aiming to collect and define mathematical vocabulary, which launches today.
you teach mathematical vocabulary, how do you define its meaning?
you exact, choosing your words specifically?
Do you give a written definition?
Do you give multiple explanations?
Do you use diagrams? Metaphors?
Connect to previous vocabulary?
As part of our work at Cambridge, creating a Framework for mathematics learning, we are creating a network of semantic links across nodes in our mathematical layer – and we initially thought we could just import a mathematical glossary from somewhere else to populate this. But we found so many inconsistencies, technical errors, and definition loops in many existing glossaries that we decided to make an app to ask the mathematical community what they thought, with the aim of developing a crowdsourced, multi-layered collage which takes into account different layers of mathematical experience.
Aperiodipal and MathsJam regular Rob Eastaway organised an inter-MathsJam competition for last month’s events, challenging Jams to make Fermi estimates on the back of an envelope. The prize was a copy of his new book, Maths on the Back of an Envelope. Here Rob gives a summary of the entries he received, and shares his favourites.
Regular attendees of MathsJam will know that in September, Katie Steckles kindly allowed me to hijack the evening (in the nicest possible sense) by posing some envelope-related challenges, in celebration of the publication of my new book Maths On The Back Of An Envelope. In addition to some envelope-related puzzles, there was also an open challenge to Maths Jam groups to come up with their own back-of-an-envelope problems, with the chance to win the book as a prize.
The Bank of England has announced, following a public poll, that the new £50 note will feature mathematician, cryptographer and computer science pioneer Alan Turing. While this might seem like unambiguous good news, the issues it raises are more complicated than they first appear. Here’s a guest post from LGBT+ mathematician Calvin Smith with his thoughts on the decision.
It’s obviously fabulous that Alan Turing is being recognised on the new £50 note, but this joy at seeing a gay mathematician given this recognition is tainted with the memory of his cruel treatment by the society of the day and the ongoing persecution of queer and trans people today.
This is a guest post from Philipp Legner, the creator of Mathigon – an interactive maths education platform.
Every year, thousands of students around the world ask themselves why they have to learn mathematics. Calculators can do long division. You can look up the quadratic formula on the internet. And when will you ever need calculus in everyday life? It seems like they have a point.
In fact, the maths curriculum has not changed significantly in the last 50 years. Its primary focus is on memorising rules and procedures which can be used to solve standardised exam questions. I created Mathigon because I strongly believe we need to change this – not only to make mathematics more enjoyable for students, but also to teach different skills that are much more useful in life: problem-solving, abstraction, logical reasoning, creativity, and curiosity.
In 2017, the University of Bath hosted the first Talking Maths in Public conference, a gathering for UK maths communicators. As part of the event, attendance bursaries were awarded to students interested in maths outreach, and the recipients of the bursaries wrote about their experiences. To celebrate the fact that a second TMiP conference will be happening this year (booking is open now, and we’re all going to be there!), we’re sharing their report of TMiP 2017. You can find out more about this year’s event (which also includes a bursary scheme) at talkingmathsinpublic.uk.
This post was jointly written by Imogen Morris, (University of Edinburgh), David Nkansah (University of Glasgow) and Olivia Sorto (University of Edinburgh).
The programme for this year’s Cheltenham Science Festival has now been released, and tickets go on sale to members today (general booking opens next Wednesday). We asked Cheltenham local and science festival regular Martin Whitworth to send us his pick of the events for the mathematically inclined.
Festival season will soon be upon us. In a recently announced programme of over 200 events, the 2019 Cheltenham Science Festival includes many that will be of interest to the mathematically-minded, including events by maths presenters Marcus Du Sautoy, Ian Stewart, Matt Parker, Katie Steckles, Zoe Griffiths, Ben Sparks, Kyle D Evans and Hannah Fry.
