People often stop me in the street and say: "You are Brady from Numberphile. Can you recommend a good mathematical book for Christmas!"<br />
<br />
This is entirely untrue. It has never happened.<br />
<br />
However I will use this blog post to recommend some books written by people from Numberphile videos.<br />
<br />
This list of not exhaustive, just a few that sprang to mind while I was waiting for my computer to process a video.<br />
<br />

<br />
Matt Parker's shiny new "<a href="http://bit.ly/Matt_4D_US">Things to Make and Do in the Fourth Dimension</a>" is cracking - very funny like the man himself.<br />
<br />
You can buy on Amazon in the <a href="http://bit.ly/Matt_4D_UK">UK</a> and <a href="http://bit.ly/Matt_4D_US">US</a> - or get <a href="http://bit.ly/Matt_Signed">a signed copy from Matt</a>.<br />
<br />
Simon Singh's <a href="http://bit.ly/SinghBook">The Simpsons and Their Mathematical Secrets</a> - great hidden gems from the TV show (plus Futurama).<br />
<br />
Simon's <a href="http://amzn.to/1jWqMTa">other books are great too</a> - <a href="http://bit.ly/SinghSearch">check him out on Amazon</a>, etc.<br />
<br />
<a href="http://bit.ly/BellosBooks">Alex Bellos</a> - of cake cutting fame - has got <a href="http://bit.ly/grapesmath">Alex Through the Looking Glass (aka Grapes of Math)</a>. It is the sequel to <a href="http://amzn.to/1l0yX46">Alex's Adventures in Numberland (aka Here's Looking at Euclid)</a>.<br />
<br />
Ed Frenkel has <a href="http://amzn.to/1g6XP6j">Love & Math</a> - well worth a look.<br />
<br />
Ron Graham - yes, that Graham - has <a href="http://bit.ly/MagicalMath">Magical Mathematics</a> written with Persi Diaconis (Persi is coming to Numberphile soon!)<br />
<br />
<a href="http://bit.ly/MazurBooks">Barry Mazur does great books too</a>.<br />
<br />
That'll do for now... Will add some more later perhaps.<br />
<br />
Clearly I am biased towards Numberphile contributors - what did you expect!?<br />

If you are a scientist, science student, teacher or somehow involved in science, we need your help.<br />
<br />
We are collecting "science selfies" of people from <a href="http://en.wikipedia.org/wiki/Commonwealth_of_Nations">Commonwealth countries</a>.<br />
<br />
Professor Martyn Poliakoff would like to use them in a video which will be shown at his address at the <a href="http://commonwealth.royalsociety.org/">Commonwealth Science Conference 2014</a> being held in India.<br />
<br />
See <a href="https://www.youtube.com/watch?v=LAn20Dyh83U">his explanation here</a>:<br />
<br />
<iframe allowfullscreen="" frameborder="0" height="225" src="//www.youtube.com/embed/LAn20Dyh83U" width="400"></iframe><br />
<br />
If you can help, here are some pointers:<br />
<br />
Email: periodicvideos@gmail.com with SELFIE in the subject field to help us sort them.<br />
<br />
- It is good if the photos looks like a selfie rather than anything too pro!<br />
<br />
- Please include a name, country and what you do in the email too. This is important. It's okay if you don't want a surname to appear.<br />
<br />
- Show us in your science environment (lab, classroom, outdoors?) if you can.<br />
<br />
- The pics will be used in The Prof's video plus the video will appear here on our YouTube channel.<br />
<br />
- Sorry if we can't use them all.<br />
<br />
NEED THE SELFIES BY WEDNESDAY, 26 NOVEMBER, 2014.<br />

<br />
<div class="separator" style="clear: both; text-align: center;">

<br /></div>
It's called Things to Make and Do in the Fourth Dimension.<br />
<br />
I really recommend it.<br />
<br />
<a href="https://www.youtube.com/playlist?list=PLt5AfwLFPxWKuRpivZd_ivR2EvEzKrDUu">Matt gives a lot of time and energy to Numberphile</a>, and his main reward is enduring the mixed bag of YouTube comments! :)<br />
<br />
So it's at rare times like this we can give something back by showing support.<br />
<br />
But the main reason you should buy his book is because it's really good.<br />
<br />
Like a series of really good, funny Numberphile videos in written form. So without my dodgy camerawork and editing! :)<br />
<br />
WAYS TO BUY:<br />
<br />
<a href="http://bit.ly/Matt_Signed">A signed copy direct from Matt</a>.<br />
<br />
<a href="http://bit.ly/Matt_4D_US">Amazon US</a>.<br />
<br />
<a href="http://bit.ly/Matt_4D_UK">Amazon UK</a>.<br />
<br />
Or buy it from a book shop... Apparently they are a thing.<br />
<br />
The book looks like this in the UK and US.<br />

<span style="font-family: Courier New, Courier, monospace;">Dear Brady, Hi. </span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">My name is Filipe (or Philip) and I live in Brazil. </span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">Two years ago aprox, I was working at an Investment Company in São Paulo. </span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">I was very unhappy with my current job.
I was working insane hours and doing a job that I didn’t love. I graduated as an engineer and I love Physics and Maths. But I wasn't doing any of that. </span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">Long story short: I saw your videos, particularly <a href="https://www.youtube.com/user/sixtysymbols">Sixty Symbols</a>.
They inspired me to change my life around.
I decided to try going for a PhD. </span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">Everybody said I could not do it because I was already 3 years in the investment industry and it has been a long time since I had formally studied all the Maths and Physics. </span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">I decided to ignore these people. </span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">I quit my job, spent most of my savings on 30 day trip to England. </span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">I wanted to do a PhD in Physics. I travelled to meet people at the top universities (Cambridge, Oxford, Kings, Imperial, Nottingham...) and talked to everyone I could about my situation. </span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">In Nottingham I talked for hours (on several different days actually) with Prof Roger Bowley. Emailed Prof Martyn and talked with Prof Tony Padilla and with Samantha. </span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">And had a brilliant interview with Professor Philip Moriarty.
I explained to him what I want to do. He said that he had just the exact idea and was waiting for the right person. </span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">I received and bunch of offers and I’m starting my PhD 1st of April at <a href="http://www.nottingham.ac.uk/">University of Nottingham</a>. Philip is going to be my Supervisor. </span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">My whole life is changing. My girlfriend is considering doing a PhD as well in Medicine at Nottingham and my family is planning to move in to England the next year as well. </span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">I would very much like to thank you. </span><br />

<br />
Last night (12 September) a new chemistry building at the University of Nottingham was <a href="http://www.bbc.co.uk/news/uk-england-nottinghamshire-29188682">destroyed by fire</a>.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

<span style="font-size: x-small;">Aftermath</span></div>
<br />
It was a horribly spectacular blaze tackled by 60 firefighters.<br />
<br />
<a href="http://www.bbc.co.uk/news/uk-england-nottinghamshire-29188682">BBC NEWS REPORT ON THE FIRE</a><br />
<br />
The building was under construction, about 70% complete. It happened at night and no-one was hurt.<br />
<br />
It was <b>not</b> the university's main chemistry building, where <a href="https://www.youtube.com/user/periodicvideos">we film Periodic Videos</a>.<br />
<br />
In fact the new building was on a separate but nearby campus.<br />
<br />
However everyone in the chemistry department was looking forward to using the new labs. Our very own Professor Pete Licence was to oversee their operation.<br />
<br />

<br />
It is too early to know how the fire started and what will happen next.<br />
<br />
We had been meaning to make a film about its construction and, in fact, had recently scheduled a film shoot but cancelled at the last minute.<br />
<br />
I sincerely hope the project starts again and we get to make that film!<br />

I think some people do not realise this.<br />
<br />
And many more do not realise artist <a href="http://www.petemcpartlan.co.uk/">Pete McPartlan</a> based his depictions of characters from <a href="http://www.amazon.co.uk/gp/product/B001E454FC/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=B001E454FC&linkCode=as2&tag=numberphile02-21">the BBC adaption</a>.<br />
<br />
I requested this because I LOVE the BBC version.<br />
<br />
I believe Pete had not seen it, but watched some episodes before starting his work. I think I converted him!!!!<br />

<br />
Philosopher Jonathan Tallant discusses the role of intuition - or gut feelings - in science.<br />
<br />
It is an interesting debate. To what extent should scientists make decisions based on intuition?<br />
<br />
There are arguments for and against. Many of these have been appearing in the comments section.<br />
<br />
It also raises questions about what is <b><i>really</i></b> meant by "intuition".<br />
<br />
Here is <a href="https://www.youtube.com/watch?v=0jRppd6c5J8">the main video on Sixty Symbols</a>.<br />

<br />
As part of my preparation, I had some special friends collect some quotes about science and intuition.<br />
<br />
I did not use them in the video, but they are well worth sharing. Thanks to the people who found them. Quote finding fiends!<br />
<br />
<b><i>I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research. </i></b><br />
— Albert Einstein
Cosmic Religion: With Other Opinions and Aphorisms (1931), 97.<br />
<br />
<b><i>The intellect has little to do on the road to discovery. There comes a leap in consciousness, call it intuition or what you will, and the solution comes to you and you don’t know why or how. </i></b><br />
— Albert Einstein
Quoted in Forbes (15 Sep 1974). In Larry Chang, Wisdom for the Soul (2006), 179.<br />
<br />
<b><i>The supreme task of the physicist is to arrive at those universal elementary laws from which the cosmos can be built up by pure deduction. There is no logical path to these laws; only intuition, resting on sympathetic understanding of experience, can reach them. </i></b><br />
— Albert Einstein
Address (1918) for Max Planck's 60th birthday, at Physical Society, Berlin, 'Principles of Research' in Essays in Science (1934), 4.<br />
<br />
<b><i>It is by logic that we prove, but by intuition that we discover. </i></b><br />
— Henri Poincaré
In Science and Method (1908) translated by Francis Maitland (1914, 2007), 129.<br />
<br />
<b><i>I’m supposed to be a scientific person but I use intuition more than logic in making basic decisions. </i></b><br />
— Seymour R. Cray
In transcript of a video history interview with Seymour Cray by David K. Allison at the National Museum of American History, Smithsonian Institution, (9 May 1995), 30.<br />
<br />
<b><i>My view of the matter, for what it is worth, is that there is no such thing as a logical method of having new ideas, or a logical reconstruction of this process. My view may be expressed by saying that every discovery contains an 'irrational element,' or 'a creative intuition,' in Bergson's sense. In a similar way Einstein speaks of the 'search for those highly universal laws ... from which a picture of the world can be obtained by pure deduction. There is no logical path.' he says, 'leading to these ... laws. They can only be reached by intuition, based upon something like an intellectual love (Einfühlung) of the objects of experience.' (1959) </i></b><br />
— Karl Raimund Popper
The Logic of Scientific Discovery: Logik Der Forschung (2002), 8.<br />
<br />
<b><i>Notion without intuition is empty, intuition without notion is blind. </i></b><br />
— Immanuel Kant
In Ralph Keyesr, The Quote Verifier, 52.<br />
<br />
<b><i>Science does not mean an idle resting upon a body of certain knowledge; it means unresting endeavor and continually progressing development toward an end which the poetic intuition may apprehend, but which the intellect can never fully grasp.</i></b><br />
— Max Planck
In The Philosophy of Physics<br />
<br />
<b><i>Thoughts without content are empty, intuitions without concepts are blind... The understanding can intuit nothing, the senses can think nothing. Only through their union can knowledge arise. </i></b><br />
— Immanuel Kant

<br />
<b><span style="font-size: large;">1. What is Numberphile2?</span></b><br />
<br />
It is the second or supplementary channel to <a href="https://www.youtube.com/user/numberphile">Numberphile</a>.<br />
<br />
<b><span style="font-size: large;">2. What is it for?</span></b><br />
<br />
It is designed to host Numberphile material that I do not want to put on "<a href="https://www.youtube.com/user/numberphile">main channel</a>" for various reasons.<br />
<br />
<b><span style="font-size: large;">3. What sort of material is that?</span></b><br />
<br />
It could be anything. Mainly it is "extra material" cut from Numberphile videos. It could also just be stuff that I thought did not quite belong on the main channel or behind-the-scenes stuff. Maybe it is too niche, too long, too short, etc.<br />
<br />
<b><span style="font-size: large;">4. But I love seeing all that stuff, why not just put that on Numberphile?</span></b><br />
<br />
Because Numberphile has a large following (<a href="https://www.youtube.com/user/numberphile">about one million subscribers</a>) and casual viewers do not want their feeds clogged up with "extra material" or 2-3 videos every time I put something new out. They just want the headline act.<br />
<br />
<a href="https://www.youtube.com/numberphile2">Numberphile2</a> can be a channel for the real die-hards who want everything. Like a little club for the true believers! :)<br />
<br />
<span style="font-size: large;"><b>5. Why not just put that "extra stuff" on Numberphile (main) and make it unlisted?</b></span><br />
<br />
I used to do that, but the material then becomes impossible to find in searches. And some people do want to be able to have this turn up in a subscription feed in some form so they don't miss it.<br />
<br />
<b><span style="font-size: large;">6. Then why is some material on Numberphile2 still marked as unlisted?</span></b><br />
<br />
There are a few reasons that <a href="https://www.youtube.com/numberphile2">Numberphile2</a> videos START as unlisted and become listed later.... The main one is this: When I release a new video on Numberphile, I probably release the "extra material" at the same time and link to it from the main video. If I made them both listed, they would turn up in subscription feeds around the same time, increasing the chances that people might watch them in the wrong order. To get around this, I make the second video unlisted so it does not show in sub feeds... I then list it a few day later.<br />
<br />
<span style="font-size: large;"><b>7. Why is the logo/avatar for Numberphile2 the number 2 and not Tau?</b></span><br />
<br />
The <a href="https://www.youtube.com/user/numberphile">current avatar for Numberphile</a> is Pi on a brown paper background - a famous "number" everyone recognises and it just looks cool. Now because Tau is 2Pi, many people think that should be the logo for <a href="https://www.youtube.com/numberphile2">Numberphile2</a>. I agree that people who "get the joke" would appreciate that. But I think it would be confusing for people who do not. For a start, Pi has two "legs" and Tau has one. Some people might think Pi should be the second channel logo? The number two is just really clear and obvious... It says: "This the second channel". Sometimes it is best to not be too clever.<br />
<br />
<b><span style="font-size: large;">Should I subscribe to Numberphile2?</span></b><br />
<br />
In some ways, my advice to casual viewers is "no". I will usually link to Numberphile2 material from main videos, either via links or annotations.<br />
I will also let people know about anything great on Numberphile2 via <a href="https://www.facebook.com/numberphile">Facebook</a> and <a href="https://twitter.com/numberphile">Twitter</a>.<br />
However if you are really into all the extra stuff and not want to miss anything, than of course <a href="https://www.youtube.com/numberphile2">please do subscribe</a>.

<span style="font-family: Courier New, Courier, monospace;">My class has been studying probability and yesterday we calculated the probability of rolling a Yahtzee on the first roll. </span><span style="font-family: Courier New, Courier, monospace;"><br /></span><span style="font-family: Courier New, Courier, monospace;">So, today, <a href="http://www.numberphile.com/yahtzee/">we watched your video</a>. </span><span style="font-family: Courier New, Courier, monospace;"><br /></span><span style="font-family: Courier New, Courier, monospace;">The students were intrigued and waited for that Yahtzee with close attention. After the video, I told them, like you said, in the game Yahtzee, you get three tries. </span><span style="font-family: Courier New, Courier, monospace;"><br /></span><span style="font-family: Courier New, Courier, monospace;">So I rolled five dice...and got a Yahtzee! </span><span style="font-family: Courier New, Courier, monospace;"><br /></span><span style="font-family: Courier New, Courier, monospace;">The class and I were stunned. Utter silence and disbelieve. </span><span style="font-family: Courier New, Courier, monospace;"><br /></span><span style="font-family: Courier New, Courier, monospace;">The look of "did that really happen" on 30 7th grade faces. </span><span style="font-family: Courier New, Courier, monospace;"><br /></span><span style="font-family: Courier New, Courier, monospace;">Thank you for showing the students your perseverence of waiting through 600 some trials. </span><span style="font-family: Courier New, Courier, monospace;"><br /></span><span style="font-family: Courier New, Courier, monospace;">And thank you for making my roll look so special!!</span></blockquote>

<br />
Two recent videos from CGP Grey and Vi Hart are well worth watching (and maybe acting upon?)<br />
<br />

This video by Emily from BlinkPopShift from a while ago was also good.<br />
<br />

<br />
<b>UPDATE...</b><br />
<br />
Oh, I missed this excellent video on the topic by Hank Green.<br />
<br />
<iframe allowfullscreen="" frameborder="0" height="225" src="//www.youtube.com/embed/mc2aso6W7jQ" width="400"></iframe><br />

<br />
Guess that's because I've been busier than usual.<br />
<br />
Plenty of new videos have been coming out - will list some of the better ones below.<br />
<br />
Some of you may also know I've started working on a new podcast with CGP Grey called <a href="http://www.hellointernet.fm/">Hello Internet</a>.<br />
<br />
I've known Grey for a few years now. He has even cameoed in a few of our videos, <a href="https://www.youtube.com/watch?v=YBbBbY4qvv4">most memorably this one</a>.<br />
<br />
<iframe allowfullscreen="" frameborder="0" height="225" src="//www.youtube.com/embed/YBbBbY4qvv4" width="400"></iframe><br />
<br />
The podcast has been great fun so far (we've recorded 11 at the time of posting).<br />
<br />
The best way to follow the podcast is via things like <a href="http://www.hellointernet.fm/itunes">iTunes</a> and <a href="http://www.hellointernet.fm/podcast-rss">RSS</a>, etc… More details are at the <a href="http://www.hellointernet.fm/">Hello Internet website</a>.<br />
<br />
We really discuss everything - but I guess a major theme is life as YouTube film-makers.<br />
<br />
Other important topics have included education, freebooting and plane crashes!<br />
<br />
Our latest move has been putting the podcasts on a <a href="https://www.youtube.com/channel/UCwez9XDNV_wS0WNDZteXjgw">Hello Internet YouTube channel</a>.<br />
<br />
These are obviously a bit behind the general release of the audio podcasts, but another way to digest the show!<br />
<br />

Anyway, back to may "day job".<br />
<br />
Here are just some of the videos to come out in recent weeks.<br />

<br />
He's released the results to coincide with his new book - <a href="http://bit.ly/looking-glass-number">Alex Through the Looking-Glass</a>.<br />
<br />
Numberphile had its own, less formal poll a while back.<br />
<br />
It <a href="https://www.youtube.com/watch?v=ygqIfLHGTu4">started with this video</a>:<br />
<br />
<iframe allowfullscreen="" frameborder="0" height="225" src="//www.youtube.com/embed/ygqIfLHGTu4" width="400"></iframe><br />
<br />
And then we harvested the stats <a href="https://www.youtube.com/watch?v=-rwqnVsGFTU">to make this one</a>:<br />
<br />
<iframe allowfullscreen="" frameborder="0" height="225" src="//www.youtube.com/embed/-rwqnVsGFTU" width="400"></iframe><br />
<br />
Seven won that poll also.<br />
<br />
Here are some previous appearances by Alex on Numberphile…<br />
<br />

<br />
And his first book is <a href="http://amzn.to/1l0yX46">Here's Looking at Euclid</a> (aka Alex's Adventures in Numberland).Bradyhttp://www.blogger.com/profile/12339819735220226666noreply@blogger.comtag:blogger.com,1999:blog-44780290347799730.post-8535011845441613942014-04-04T04:33:00.000-07:002014-05-02T07:33:44.232-07:00Alan's AlbumRegular viewers will be familiar with the music of Alan Stewart.<br />
<br />
Alan is a physics teacher who composes and performs music in his spare time.<br />
<br />
I love his work and we've collaborated together on MANY videos, some of which are listed below.<br />
<br />
Well, Alan was too humble to tell me, but he has pulled together <a href="http://bit.ly/1sdwTHF">many of his best tracks into an album</a> on iTunes.<br />
<br />
<a href="http://bit.ly/1sdwTHF">Here is the link</a>.<br />
<br />
I think it's great value.<br />
<br />
Despite having many of them on my computer already (for obvious reasons), I downloaded the album myself last night and have been listening non-stop.<br />
<br />
Gorgeous background music.<br />
<br />
I especially recommend the tracks "Time Passes" and "Wait" - but maybe that is because they appear on some of my favourite videos.<br />
<br />
(As a bonus, Alan included his Good Will Hunting inspired track, which is often requested!)<br />

<br />
(Because although I love them, you are more than just numbers to me!)<br />
<br />
You can help by sending me a "selfie-style snap" of you <a href="http://www.numberphile.com">watching Numberphile</a> (maybe a favourite presenter on screen, a video you liked or hated, etc).<br />
<br />
The picture will be used in my talk and, unless you tell me otherwise, I might put some of them here on the blog?<br />
<br />
Email to numberphile at gmail dot com<br />
<br />
Include as much or as little information as you like... I'd love to know your name, where you are, maybe why you watch the videos... and your favourite number. You can include nothing or write me an essay - the pic is the crucial bit.<br />
<br />
I will reply to all of them (unless you tell me not to!)<br />
<br />
Here's a just a sample photo, but be as creative or simple as you like.<br />
<br />

<br />
There are great images everywhere of SN2014J, and <a href="http://www.youtube.com/watch?v=JtjVqmi45ds">we have done a short film for Deep Sky Videos</a> (see embed below).<br />
<br />
I emailed UK astrophotographer <a href="http://s175657640.websitehome.co.uk/CCDLandWebSite/index.html">Nik Szymanek</a> - <a href="http://www.youtube.com/watch?v=fig8WFALU_k">who features in some of our videos</a> - to ask if he had grabbed an image.<br />
<br />
Despite some cloudy nights, he managed to get this one:<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

Another friend of ours (and a world-class imager) is <a href="https://twitter.com/Avertedvision">Pete Lawrence</a> (of <a href="http://www.youtube.com/watch?v=LWw8z75AXwU">green flash fame</a>).</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
Again, the supernova was not a priority for Pete, but he did manage to grab this image:</div>

<br />
<iframe allowfullscreen="" frameborder="0" height="225" src="//www.youtube.com/embed/ab_dY3dZFHM" width="400"></iframe><br />
And indeeed I made an error showing the path of magic knight's tour, making a mis-step over the final few moves… 61-62-63-64.<br />
<br />
This one, from the video, is wrong (it is legitimate tour, but not quite magic):<br />
<div class="separator" style="clear: both; text-align: center;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgVh6JWVVqx-XSDT77hAjZPFLSgRjgtFHiaQ6egYrqJlr8DIR9dDoHmdKr6XrF9CJBd0LiM-myCYyJV6BG5eStNAEnyBUijV6qp1waulvE398BBmlXkYeruutGH0knu_IVmjxwPkx4e/s1600/wrong.jpg" imageanchor="1"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgVh6JWVVqx-XSDT77hAjZPFLSgRjgtFHiaQ6egYrqJlr8DIR9dDoHmdKr6XrF9CJBd0LiM-myCYyJV6BG5eStNAEnyBUijV6qp1waulvE398BBmlXkYeruutGH0knu_IVmjxwPkx4e/s1600/wrong.jpg" /></a></div>
<br />
And this one is right (I think):<br />
<br />

<br />
<a href="http://bit.ly/TonyResponse" target="_blank">Dr Tony Padilla has written his own response - read it here</a>.<br />
<br />
And here is a <a href="http://nyti.ms/1iftqSv">New York Times article on the video</a>.<br />
<br />
(And see <a href="http://terrytao.wordpress.com/2010/04/10/the-euler-maclaurin-formula-bernoulli-numbers-the-zeta-function-and-real-variable-analytic-continuation/" target="_blank">Terry Tao's blog on this topic</a> and analytic continuation, etc)<br />
<br />
This is a general response to people who have messaged and emailed about our <a href="http://www.youtube.com/watch?v=w-I6XTVZXww" target="_blank">1+2+3 video</a>… Trying to cover a few general points rather than reply to everyone individually!<br />
<br />
1. Firstly, thank you for taking the time to message and (in most cases) being so polite and constructive. It is great that the <a href="http://www.numberphile.com/" target="_blank">Numberphile</a> audience is so passionate.<br />
<br />
<iframe allowfullscreen="" frameborder="0" height="225" src="//www.youtube.com/embed/w-I6XTVZXww" width="400"></iframe><br />
<br />
2. I think many people have not watched the second, <a href="http://www.youtube.com/watch?v=E-d9mgo8FGk" target="_blank">more detailed video</a>. I would suggest it before firing off a lengthy email.<br />
<br />
<iframe allowfullscreen="" frameborder="0" height="225" src="//www.youtube.com/embed/E-d9mgo8FGk" width="400"></iframe><br />
<br />
3. For those taking issue with 1-1+1-1 etc, I would also suggest watching <a href="http://www.youtube.com/watch?v=PCu_BNNI5x4" target="_blank">our video on Grandi's Series</a>.<br />
<br />
<iframe allowfullscreen="" frameborder="0" height="225" src="//www.youtube.com/embed/PCu_BNNI5x4" width="400"></iframe><br />
<br />
4. The concepts in these videos include some more obscure techniques, such as <a href="http://en.wikipedia.org/wiki/Analytic_continuation" target="_blank">Analytical Continuation</a> and <a href="http://en.wikipedia.org/wiki/Ramanujan_summation" target="_blank">Ramanujan Summation</a>. It is worth reading about them.<br />
<br />
5. There is <a href="http://en.wikipedia.org/wiki/1_%2B_2_%2B_3_%2B_4_%2B_%E2%8B%AF" target="_blank">a Wikipedia article on 1+2+3+4</a>. Check it out.<br />
<br />
6. <a href="http://www.numberphile.com/" target="_blank">Numberphile</a> is not mathematics text book. In a short video for a popular audience you should not expect the level of detail and background explanation possible in a tome that is hundreds of pages long. Also some topics covered in the videos may involve numbers in our lives without necessarily being mathematical!<br />
<br />
7. These are unscripted interviews. There's little point getting upset about imprecise or layman's language… I would hate to change that informal and spontaneous format. I know some of you have a PhD is mathematics and know this stuff back-to-front… But spare a thought for those who do not.<br />
<br />
8. We often look at some advanced, obscure and controversial topics. There's no denying that some physicists do use this -1/12 result, whatever you may think of it.<br />
<br />
DR TONY PADILLA (featured in the videos) has written a further article - <a href="http://bit.ly/TonyResponse" target="_blank">here is a link</a>.<br />
<br />
<a href="http://terrytao.wordpress.com/2010/04/10/the-euler-maclaurin-formula-bernoulli-numbers-the-zeta-function-and-real-variable-analytic-continuation/" target="_blank">ALSO RECOMMEND TERRY TAO'S BLOG ON THIS VERY TOPIC</a> (and he's a Field's Medallist!)<br />
<br />
9. On the topic of Divergent Series, <a href="http://en.wikipedia.org/wiki/Divergent_series">the Wikipedia article is very good</a> and I'm also advised that Chapter XIII of Konrad Knopp's book "Theory and Application of Infinite Sequences and Series" is excellent if you can find it.<br />
<br />
10. You should <b>NEVER</b> disregard what your teachers or professors tell you (especially if they are setting yours tests and exams) - but it can be fun hearing what professional people are doing and the techniques they use?<br />
<br />
11. Apparently this play - <a href="http://en.wikipedia.org/wiki/A_Disappearing_Number" target="_blank">A Disappearing Number</a> - is partly based on the result. I'm told it's quite good.<br />
<br />
Most importantly just remember, <a href="http://www.youtube.com/watch?v=w-I6XTVZXww" target="_blank">it is a YouTube video</a>. It is supposed to be fun and thought-provoking. Don't get upset.<br />
<br />
Many people send very long and detailed emails… I really appreciate this but please bear in mind that a) I cannot answer them all and b) I am not a professional mathematician (though many of the interview subjects are).<br />
<br />
A great place to leave your comments, ideas and arguments is in the YouTube comments where other people will see them, and maybe share their own views.<br />
