Happy New Year! And welcome to the first Carnival of Mathematics of 2014. The Carnival is a monthly roundup of blog posts on or related to mathematics, from all over the internet. Posts are submitted by authors and readers, and collated by the host, whose blog it’s posted on. This month, the Carnival has pulled in here at The Aperiodical, and we’re all ready with our party hats for the celebration of mathematical blogging that implies.

Tydlig, a nice calculator for iOS
[youtube url=http://www.youtube.com/watch?v=xbXaKxxUomE]
Closer to a computer algebra system than a traditional calculator, this new app for iOS (iPhone and iPad) allows you to make calculations and create graphs, and mess around with the values to see what that does to the output. It looks like this is achieved without using any (explicit) symbolics, which results in a neat and pretty interface, made even nicer by the fact that you can move calculations around the screen and arrange them as you want. The name, Tydlig, is the Swedish word for ‘clear’.
If anyone’s willing to download a copy ((TYDLIG is also the name of an induction hob sold by IKEA, and if anyone wants to buy and review that too, you’re welcome to, but not for this site.)) ($4.99 on the App Store) and try it out, we’d be interested to hear how easy it is to use, and what other nice tricks it’s got up its sleeve. Use the ‘Send something in’ link above to get in touch, or leave a comment below.

By Napier’s bones! A new exhibition celebrating the inventor of logarithms
Put away your calculators – the National Museum of Scotland in Edinburgh has announced that it will host an exhibition all about John Napier to celebrate the 400th anniversary of the publication of his treatise on logarithms, Mirifici Logarithmorum Canonis Descriptio.
Napier’s pioneering work on logarithms offered simple and elegant solutions to previously laborious and error-prone calculations; enabling more calculations to be completed in an hour than had previously been completed in one day. From the introduction of the decimal point to the development of slide rules and ‘Napier’s rods’, this exhibition will explore how Napier’s revolutionary innovations advanced and influenced mathematics from the 17th Century to the modern day.
Power of Ten will run from 28 March to 6 July, and entry is free.

OEIS contest for January AMS/MAA meeting
Top chap (and newest Aperiodipal?) Neil Sloane, founder of the Online Encyclopedia of Integer Sequences, wrote in to direct our attention towards a “best new integer sequence” contest being run on the sequence-fans mailing list.
Any sequence submitted between the middle of December and the middle of January is eligible. The winners (of which there will be at least three) will each receive a signed copy of the original 1973 Handbook of Integer Sequences, as well as the highly coveted “nice” keyword on their encyclopedia entries.
Particularly mathematical New Years Honours 2014
With the announcement of honours for 1,195 people in the 2014 New Years list, it’s time for the latest in our ongoing Honours-watch series of posts. In this, we search arbitrarily for ‘mathematics’ in the PDFs of the various lists, and hope our well-informed readers fill in the blanks where actual knowledge is required.

Alan Turing receives Royal Pardon
It was announced this morning that mathematician and codebreaker Alan Turing has been posthumously granted a pardon for his conviction in 1952 for gross indecency. The pardon is issued under the Royal Prerogative of Mercy by the Queen, after intervention from justice secretary Chris Grayling. The conviction was at the time standard for persons found to be practising homosexuals, and was applied to more than 50,000 cases. Turing’s punishment was chemical castration, although many others in his situation were sent to prison.
