 note on talking about data comes in all shapes and he's here today. So yeah Tim. Okay and I think it will be appearing on the screen. I have nothing specific about big data to say just now but my science fiction novel within Stuart is just now published. And can you scroll up a little bit? Now if I was a lot more agile I might beep it up. Wonderful line we have from Stephen Baxter. If you're science fiction fans you'll know Baxter is a big science fiction author and Niven is an even bigger one so this is rather grand company to be in. And I won't tell you the premise because initially you have to see if you can guess the premise which is a nice puzzle in the first part and then we have endless interesting implications of the premise as society for transport for cookery for sex it affects absolutely everything. So a very geeky book I'm glad that Baxter said it was a nice dramatic and driven story but also you have the great game of trying to figure out where the author is wrong where it doesn't make sense. So I look forward to a lot of email saying ah but so I don't know why I'm invited to plug my book here because it isn't big data but I'm very grateful and I will stop taking up your time unless anybody wants to ask a question and there is time for questions is there? Oh one more piece of information the link to Amazon doesn't work yet give it a few days you can order the ebook if you like ebooks direct from the publisher from here but from the paperback is from Amazon and it's not quite yet but very very soon. So I feel happy and I hope some of you will find the book exciting interesting or worth a mental argument with. Thank you very much. Thank you Tim. So a couple of announcements before we start the next talk the BOF sessions are starting in auditorium three so there's a math and stats BOF happening from three to four and there's the alternative data BOF start
