### Puzzle from Proof: Seven Gold Rings

In our latest podcast about the movie "Proof", we set the following puzzle:

Tom employs a labourer, who is going to work for him for seven days.

Every day he wants to pay the labourer one gold ring for each day they have worked.

Unfortunately Tom is a strange person who keeps his gold in the form of a chain with seven gold links, and a miser who doesn't like wasting gold. What is the minimum number of links that Tom must cut in order to make sure the labourer can always leave with the correct number of gold links?

### MATM Appendix: Who the hell are we?

You've listened to us talk, but what are our credentials? What do we know? What are our backgrounds? When should you take our "facts" at face value and when should you call bullshit?

### Puzzle from 21: How old will Ben be on his next birthday?

Here's the puzzle from the first episode of the podcast, Maths at: the Movies, 21, where we learnt that mathematicians like Fibonacci Birthday cakes.

However, here's the question for this week. Comment below, or send your answer to podcastmaths@gmail.com, tweet us @podcastmaths, find us on facebook, to receive a shout-out on a future podcast and a warm fuzzy glow.

"Ben is currently 50 years, 50 Months, 50 Weeks, 50 Days, and 50 Hours old. How old will he be on his next birthday?"

(Ben would like to point out he is nowhere near that old, despite Tom's insinuations)

### Maths at the Movies: 21

In our first ever episode we watch the movie 21.

This film has it all: racism, sexism, disableism... and a smattering of mathematics.

Join us as we peel back the layers of gambling and card counting to reveal why you should never keep your money in your ceiling and why you'll never be as good a mathematician as Kevin Spacey.

### Who are we?

is a Lecturer in Applied Mathematics at Cardiff University. He was an undergraduate, graduate, doctorate and post-doctorate at the University of Oxford, St John's College since 2004 and thought it was about time to leave in 2017.

He specialises in mathematical biology and focuses on the pattern formation behind fish spots and zebra stripes. He also researches mathematical models of stem cells movement. The hope is that by understanding how stem cells move we can influence them and, thus, speed up the healing process.

When not doing mathematics he is a keen participant in mathematical outreach workshops and has given a variety of popular maths lectures nationally and internationally. He has previously worked for the BBC, illustrated Marcus du Sautoy’s book, "The Number Mysteries"; set questions for the popular maths show “Dara O’Briains school of hard sums” and helped redesign the the London Science Museum's Mathematics Gallery.

is a Lecturer in Statistics, in Mathematical Sciences, and the Southampton Statistical Sciences Research Institute. He received a MA in Mathematics and Diploma in Computer Science from University of Cambridge, Pembroke College.

Previous employments include:
• working on an EPSRC grant at Queen Mary, University of London, entitled “Design of Experiments for Complex, Large Scale Networks".
• PhD from Queen Mary, University of London, thesis: “Design of Experiments for Packet Communication Networks”.
• MSc in Applied Statistics and Operational Research from Birkbeck College, University of London.
