Maths money savers

Matt Parker, who we heard from in Travels in a Mathematical World episode 31, stars in a new series of videos for the TDA. In each, Matt uses maths to solve a problem involving money. According to a press release the aim is to recruit maths teachers.

Dude, where's my petrol money

Podcast: Episode 44 - Andrew Cates, his career

These are the show notes for episode 44 of the Travels in a Mathematical World Podcast. 44 is the smallest number which is the sum of a reversible pair of non-palindromic primes. More about 44 from Number Gossip.

Dr Andrew Cates, CEO of SOS Children, talks about his career working for Shell as strategy consultancy, country manager for Shell in Côte d'Ivoire, as co-ordinating manager for "everything Shell sold to ships worldwide" and in charge of gas and power business in Europe. Andrew also talks his recent work for charity SOS Children, the world's largest orphan and abandoned children's charity.

This recording was made live during the panel discussion at the Young Researchers in Mathematics 2009 Conference at the University of Cambridge. Find out more about future events at the Young Researchers in Mathematics website. You can watch the whole panel discussion, including an extended question & answer session as "Where has maths taken you?"

Podcast: Episode 43 - Victor Arulchandran, wave dispersion and PhD skills

These are the show notes for episode 43 of the Travels in a Mathematical World Podcast. 43 is the smallest non-palindromic prime which on subtracting its reverse gives a perfect square. More about 43 from Number Gossip.

This time on the podcast Victor Arulchandran of Brunel University talked to me (in a quite noisy tea room!) about his PhD topic looking at wave dispersion and the wide range of applications of that area of mathematics. Victor's supervisor is Julius Kaplunov. There is a wealth of information on waves and dispersion in the Dispersive PDE Wiki. There is a page on that wiki detailing dispersion relations.

Victor also talks about the skills he is able to acquire during his PhD which will aide his future career aspirations in financial modelling. There is good information on skills employers are looking for in the IMA Mathematics Careers Advice leaflet and more information on postgraduate study at the Maths Careers website.

Barcodes

Recently I found out via @beverycool on Twitter that Wolfram|Alpha encodes text as barcodes. For example, here is Peter Rowlett:

Just imagine the uses! Well. Hmm. Not sure how useful, but it certainly seems neat! ;)

@beverycool is suggesting the Google Doodle for 7th October (a barcode of the word Google) might have been created using Wolfram|Alpha. From a blog post on walyou.com by Eran Abramson I discover the 7th October was the anniversary of the Barcode patent in the US by Joseph Woodland and Bernard Silver in 1952. And from a comment on that post by Scott Blake I found this video of Scott scanning the onscreen barcode: "Google barcode logo actually scans!!!".

Podcast: Episode 42 - Ed Galea, His career, part 2: Crowd evacuation modelling

These are the show notes for episode 42 of the Travels in a Mathematical World Podcast. 42 is The Ultimate Answer to The Ultimate Question of Life, the Universe and Everything.

Last week we heard Professor Ed Galea of the University of Greenwich talk about his career from origins in astrophysics and how this led to industrial steel casting and fire modelling. This week on the podcast Ed's career develops to look into crowd evacuation modelling. There is a wealth of information about Ed's research on his webpage and on the website of the Fire Safety Engineering Group (FSEG).

On Ed Galea's webpage, you can watch a piece from BBC News with Ed talking about aeroplane evacuation. You can listen to audio of a piece with Ed talking to The World on the 7th anniversary of 9/11 on that tragedy and what we can learn about skyscraper evacuation.

Podcast: Episode 41 - Ed Galea, His career, part 1: How astrophysics leads to steel casting and fire modelling

These are the show notes for episode 41 of the Travels in a Mathematical World Podcast. 41 is prime, the smallest non-palindromic prime which on subtracting its reverse gives a perfect cube.

In this episode, part 1 of 2, Professor Ed Galea of the University of Greenwich talks about his career in various aspects of magnetohydrodynamics, from origins in astrophysics and how this led him to industrial steel casting and fire modelling. We learned about magnetohydrodynamics from David Fearn in podcast episode 33. If you are interesed in this topic you can get an overview from Wikipedia: "Magnetohydrodynamics", with plenty of links to further reading from more reliable sources. There is a wealth of information about Ed's research on his webpage.

In part 2 next week Ed talks more about crowd evacuation.

Podcast: Episode 40 - Maths news with Sarah Shepherd

These are the show notes for episode 40 of the Travels in a Mathematical World Podcast. 40 is, in English, the only number whose constituent letters appear in alphabetical order. More about 40 from Number Gossip.

This week on the podcast I met Sarah Shepherd, PhD student at the University of Nottingham and Editor of iSquared Magazine and we discussed some maths news. Links to all the articles we mentioned are below.

British Science Festival
There was an active mathematics component at the recent British Science Festival. Information about the festival is available on the British Science Festival website. Read the BBC daily reporters log by Sue Nelson. Read "Simon Singh: My quest for a perfectly awful formula" in the Guardian.

Turing apology
Alan Turing has received a posthumous apology from the UK Government for the treatment he received for being gay. Read the apology on the Number 10 website, watch a BBC News video giving some background and listen to a short piece from the Today programme. You can read "How Alan Turing Finally Got a Posthumous Apology" by petition organiser John Graham-Cumming.
Guardian piece: "PM's apology to codebreaker Alan Turing: we were inhumane". BBC: "PM apology after Turing petition". Alan Turing's life and work was covered by Noel-Ann Bradshaw in podcast 21.

First one trillion cases of congruent number search
Mathematicians have resolved the first one trillion cases of an ancient mathematics problem using "a clever technique for multiplying large numbers". Read "Mathematicians Solve 'Trillion Triangle' Problem" at Science Daily.

Andy Burnham and exponential growth

President Obama has presented the Presidential Medal of Freedom to Stephen Hawking for "overcoming disability to push the boundaries of science". Read "Obama presents presidential medal of freedom to 16 recipients" from the Guardian.

Brain chaos
Researchers believe the brain operates in a state of "self-organised criticality", on the boundary between stable and chaotic behaviour - and this is a good thing. Read "Disorderly genius: How chaos drives the brain" in New Scientist.

MTi journal launched by ATM at MEI conference
The Association of Teachers of Mathematics (ATM) has launched Mathematics Teaching interactive (MTi), an online journal to accompany their print journal Mathematics Teaching, at the Mathematics in Education and Industry conference.

"Odd day" and other 'significant' dates

Turing apology

With the news that Alan Turing has received an official apology from the government over the terrible treatment he received due to his homosexuality quickly vanishing into the distant past, I decided to dig out a couple of photos I took on a visit earlier in the year. I ran a stall at a postgraduate conference at the University of Surrey. The University is in Guildford where Alan Turing lived as a child and he is honoured by a bronze statue outside the Austin Pearce Building where the conference took place. My photo of this and the corresponding plaque are below:




Read the apology on the Number 10 website, watch a BBC News video giving some background and listen to a short piece from the Today programme. You can read "How Alan Turing Finally Got a Posthumous Apology" by petition organiser John Graham-Cumming.
