Took these pics last night as Professor Martyn Poliakoff and Neil Barnes prepared for our lecture on Friday night at the Royal Institution.
Preparations for Lecture
More fun with the Nepal Flag
A while back we posted a Numberphile video about the constitutional instructions for drawing the flag of Nepal.
I subsequently received a few emails.
These include three from a chap named Edward Rousso who followed the same instructions and used Illustrator.
Here are his pics as they came through:
For comparison, here's a Flickr link to Dr James Grime's hand-drawn version as seen in the video.
And finally, here's a video response to our video by a chap named Simon Tyler who used something called GeoGebra.
A Special Visitor from Italy
I'm on holiday at the moment, but was just CC'd on a great email from Professor Martyn Poliakoff in Nottingham.
Here it is, with some pictures too. (The email was addressed to Chris Rudd, pro-vice-chancellor at the University of Nottingham)
Dear Chris,
Yesterday (Sept 15th) was, I think, the best day that we have ever had for PTOV because a 10-year old Italian fan, Edoardo, was brought specially to Nottingham by his mother as his 10th birthday present.
Edoardo attended the demonstration lecture for A-level students, sitting in the front row, and putting up his hand to answer questions!
He brought some biscuits as a present for the team, and cards for Pete, Sam, Debbie and me.
After the lecture he visited my office and went to lab with Pete Licence.

Edoardo has watched all the videos, quoting from them, and even reciting perfectly the limerick about DDT!
His mother said that last year Edoardo chose "Chemistry" as the conversation topic for his English test at school.
It was really a moving experience. It's occasions like this that makes it all worthwhile.

Your Mind Is Like Soup
The other day I received this tantalizing picture via Twitter.
It is a quotation at the front of a master's thesis.
Quoting Professor Poliakoff was Lasse Nørfeldt, who was about to complete his masters in pharmaceutical sciences.
He was on the eve of defending his thesis and did not elaborate on the tweet, promising he would do so later.
Well he has since emailed with more details and pictures.
"I started studying pharmacy in 2006 at the Faculty of Pharmaceutical Sciences at Copenhagen University.
"During my first semester I had a course in fundamental chemistry and was given the task of learning all the atomic numbers in the periodic table (except the Lanthanoids and Actinoids).
"I found a site that had some flashcards and actually learned all the numbers (most I forgotten by now).
"During my search I came across the periodic videos channel and LOVED it! I believe that this was my first youtube subscription.
"During my study I have continued to watch this channel (along with the other channels that emerged) even though I don't so much chemistry any more.
"I am very inspired by the way that the professor and the other scientists communicate the scientific knowledge.
"They really boil it down to an interesting soup of knowledge. During my Master's Thesis I was dealing a lot with scientific knowledge from other disciplines such as computer science, material engineering and mechanical physics.
"It was very difficult to understand since much of this knowledge is not so common in pharmaceutical science and I therefore kept reminding me of my favorite citation: Your mind is like soup...
BTW: My favorite dish is soup and opponent really liked my thesis...
PS: Could you please make a video about air pressure and altitude? My mind needs to be stirred again.
Yours Sincerely / Venlig hilsen Lasse Nørfeldt
A Little Rubik's Game to Play
On Numberphile we're uploading a series of videos about the Rubik's Cube.
One of the highlights is a huge compilation of videos submitted by our viewers.
Hidden away in this monster video are all sorts of gems...
Can you find or count the following:
How many people are solving the cube with blindfolds?
How many cubes break while being solved?
Can you see me (Brady)?
Can you see three shots which feature the world's top speedsolver Feliks Zemdegs?
Can you see Michael from the well-known YouTube channel Vsauce?
Can you spot Brady's fitness instructor Phil!!!?
Speaking of fitness, can you see someone solving the cube on a treadmill?
How many animated "self-solving" cubes appear?
Can you spot the underwater cube?
Most of our cubers are male... But how many females can you see?
Someone cubing while singing along to a Justin Bieber song?
Can you see the cuber with the brown Numberphile website on his screen?
How many cubes appear which are not the standard 3x3?
Did you spot a magic trick?
Can you guess which video is a self-admitted forgery (not the "magic trick" but someone else not really doing it - and this doesn't include sped-up videos which appear!)
And finally, how many Rubik's Cube appear in the video (not including he same cube being shown twice at different parts of the video)?

A nice story from Barry
I think anyone following Numberphile will be familair with my current One-Roll Yahtzee obsession.
The odds of rolling five matching dice are 1 in 1296.
Anyway, I recently received an email from a chap named Barry Smith.
Here it is:
My name is Barry Smith and I really enjoy what you guys are doing on Numberphile. Ive been keeping up with all of your one roll Yahtzee videos, and they made me want to share with you a related story.
It has been a while since it happened, but I believe you got 2 rolls for $1, but the catch was that you got only one attempt per night.
Anyways, I was right next to my Brother-in-law and witnessed him roll a One Roll Yahtzee with 6s on his first attempt. He won around $850 cash.
It was one of the luckiest things I have seen in my life.
Anyways, after watching your one roll yahtzee videos it made me want to dig up the picture I took of his roll and share it with you. Attached is the picture.
Amazing Yahtzees
One viewer names Seth (right) not only sent in a Yahtzee - he also included a remarkable moment when one dice came to rest on top of another (links directly to the moment).
Some viewers seemed unimpressed - but I think it's far rarer than rolling five matching dice.
