Hi all,

For those of you in the UK (or who like to travel!), I'm giving a talk at the British Science Festival in Newcastle, UK on 7th September all about the PrimeGrid project and the history of searching for large primes. Full details of the event is here:

http://www.britishscienceassociation.org/british-science-festival/primegrid-join-search-world-record-prime-number

If you're in the area, please come along - it's free but you need to book a place.

Also, if someone finds I world record GFN before then, I'll personally buy you a beer(*)

Cheers

- Iain

Just booked my ticket!

I'd already booked a ticket for a talk later in the week with an old collaborator of mine but totally missed this in the programme. Very glad you mentioned it!

I might be able to get there. Depends on whether Johnny F can finally be taught about the Rule of Law before then. Will advise.

Very nice, Iain. It would be a bit of a journey for me, sadly, but if you've got an online version of slides or a video (or will at some point in the future), please post a link.

I'll check with the organisers if there will be official recordings, if nothing else I can probably do audio myself or ask a colleague to bring a camera.

Can't make it as I live in North Carolina now, but I'm from Newcastle originally. Well, just to the east in South Shields.

Did my degree at Newcastle University (Physics) so I know that place :)

Just to bump the thread for those who didn't see it the first time, and a reminder for those who did...

This coming Saturday (7th Sept, 1.30pm), I'll be giving a talk at the British Science Festival about PrimeGrid: http://www.britishscienceassociation.org/british-science-festival/primegrid-join-search-world-record-prime-number

If you are coming along please come and say hello afterwards - it's always good to meet up with fellow crunchers. I've also got an exhibition in the Discovery Museum for the day on some more general Supercomputing and computational science topics so please stop by! (http://www.britishscienceassociation.org/british-science-festival/what-makes-supercomputer-super)

Hope to see many of you there!

Hi all,

In case anyone is interested in listening in, I finally put the audio (MP3) and slides from my talk online. Feel free to download, share, re-use as you see fit.

Cheers
