A while ago an email was posted to a mailing list I am on. The IMA, my former employer and the professional body of which I am a member (and I hope you are too), are redeveloping their website and the redeveloped site will have a section “I Love Maths”. The email asks for suggestions of content to link to and explains this will contain:

• interesting articles on the history of mathematics;
• biographies of mathematicians;
• mathematical problems;
• mathematical podcasts.

I sent an email back with a couple of suggestions. Then yesterday, on a sort of whim, I asked on Twitter for “Suggestions please: What websites, blogs, video, audio & online written resources could I link to to enthuse people about maths?” Here are the replies I have received so far. More welcome in the comments or on Twitter.

@CloudoidLtd and @joshgiesbrecht recommend the charming Vi Hart and her doodlings. Here’s an example:

@jennycaddick recommended Plus Magazine. When I would give my careers talk for the IMA I would point out the Plus Careers Library and I’d always ask: “Do you read Plus?” and comment: “If you don’t, you should. It’s good!”

Plus magazine opens a door to the world of maths, with all its beauty and applications, by providing articles from the top mathematicians and science writers on topics as diverse as art, medicine, cosmology and sport. You can read the latest mathematical news on the site every week, browse our blog, listen to our podcasts and keep up-to-date by subscribing to Plus (on email, RSS, Facebook, iTunes or Twitter).

@acmescience pointed out the YouTube channels singingbanana by James Grime and TDAmathsmoneysavers by Matt Parker. Here are samples:

As well as his blog, reflectivemathsteacher, @reflectivemaths recommended Murderous Maths.

The books, the extra bits, games, hints, tricks, puzzles… they’re all here !

You can watch a video here:

@dendari recommended Math Playground:

Welcome to Math Playground, an action-packed site for elementary and middle school students. Practice your math skills, play a logic game and have some fun!

@dansmath pointed me to his site dansmath.com, “for free lessons and link to my math(s) podcasts!”

@numberprose pointed me to the NumberProse Blog:

Welcome to my blog. I will share my thoughts on a variety of math-related topics. Sometimes when I go to a Spanish tapas restaurant after sampling some tapas, my taste buds are tantalized but I am left hungry for more. I need an entrée! Similarly if you are hungry for more information after reading a particular blog entry then click on the links for more in-depth reading.

@pkauppila recommended Math-Blog.com.

Math-Blog.com is dedicated to promoting the beauty of Mathematics at every level. It was started in 2007 by Antonio Cangiano, a Software Engineer and Technical Evangelist employed by IBM, who is very passionate about math. It began as a personal blog, but following its early success the site is now accepting external submissions and contributions by guest writers, with the long-term goal of making it a hub for those who intend to publish high quality, interesting and easy to follow mathematical articles on the Web.

Last but not least, @AbdelRSS pointed out the magazine published by his employer the RSS, Significance Magazine.

Statistics are key to understanding news, developments, and decisions. Updated daily, Significance brings you a statistical view of what’s going on in the world.

Okay, I’m off to send in these suggestions. What did I recommend in my first reply? Well the IMA already know about the Travels in a Mathematical World Podcast but I recommended Strongly Connected Components and of course gave a nod to the Math/Maths Podcast. For history I sent in the MacTutor history of mathematics archive, the BSHM web resources section (although I’ve been asked to update this) and the new Bite-sized History of Mathematics written materials and podcast. I pointed out the first of three videos Samuel Hansen and I made on our History of Mathematics Tour of Nottingham and the two videos of lectures I gave for History of Maths and x, on cryptography and gravity. For blogs, I suggested the Big Two, Terence Tao’s What’s new and Tim Gowers Gowers’s weblog, and also Greenwich Maths Time. For interesting reading I suggested Plus Magazine and Maths and Sport. For puzzles and problems I suggested Cut-the-Knot.org and recommended a link to MathsJam.

What would you recommend?
