My fave number is 4 – it goes with everything.
My favourite number is 7
I will say e = 2.71828183 because it neutralizes pi in Euler’s identity :p
e^(i*pi) + 1 = 0
http://en.wikipedia.org/wiki/Euler's_identity
525.600
1, its the most complete (unity) but its also the loneliest.
Well, for this contest, it’s either 18 or 82.
0 (but not NULL)
13
13, because it’s lucky
91!
My favorite number is 5. It seems like a very round number to me since I was little. I have always liked it… maybe it also has something to do with me having a crush on a guy in 3rd grade, whoes class number was “5”. :)
e.
Really I have four, e, pi, i, and 1
1.61; approximately the golden ratio
And approximately the ratio of successive Fibonacci numbers
My favorite number is e. Works so hard, gets no respect.
2
Even and prime.
e (the constant)
0.7734
sqrt(-1). Because of our long history together, which has not always been pleasant for either of us.
21. It’s divisible by 7 and 3, among other things. Pretty much win.
the number 3
5, it is also my favorite prime number
Is that a parrot on the cover?

My favorite number is 4, because that’s the number of people in my family!
2
Because it’s the only even prime number
My favorite number is the Feigenbaum constant, 4.66920… It’s a fundamental number that strangely pops-up in all sorts of apparently unrelated chaotic systems like the Mandelbrot set, Logistic map.
8 is my favorite number.
6.0221415 × 1023
8
21. My sons birthdate.
Zero. It’s quite powerful for something with no value.
16!
zero, where everything starts.
e
1729! Ramanujan!
My favorite number of the day would be 4, because I hope to be one of the 4 winners.
3
Need to start figuring out how to wrap my head around R properly sooner or later…

9 because sounds like nite
-0, because it was invented by computer scientists.
1, number one, the one before all others, primary, basic, selfish, the self who knows itself as one, the one and only, only one is needed, … and then there is another one, the best one, the other one, the one which makes one complete

2, because I already have 2 R books and could use another one.
The ever popular 42. Thankfully, it is at random and not for being unique.
7
My favorite is 0. It could never be 7 because as a kid I was told that 7 ate 9 and I have never forgiven it.
my favorite number is either pi or e.. I teach Alg 2 and Statistics, so I get to use both quite a bit :)
BTW – thank you so much for your site – I often use your examples of how real world data can be shown (and nicely) as examples of where kids can go with the math that they learn.

5 – Prime Number and it occurs in so many (meaningful) contexts
New to R, would love this book.
I’ll go with 22!
R these physical books or R they eBooks?

int favNum = rand();
Favorite number is 7, but I’m pretty happy with most small integers.
What a fantastic giveaway! I have been tinkering with R and would greatly appreciate such a great resource.
My favorite number is 5, mostly because of pentagons.
5!!! Lame I know, but I have my reasons.
Phi, the golden ratio

Favorite number? Zero.

Nice! My favorite number is 22 (old high school basketball jersey number)
4 – because it is square
623
I like how 6 = 2 x 3
And it’s my birthday.

200 (at least when I started). Round numbers make me feel good but for bigger, more challenging problems, I like to use R.
33
Zero. Is there anything it can’t undo?
I like 15. And I would love me a copy of the R Cookbook. The SQL Cookbook is very good too.

I have a long running battle with the number two. I have to choose it, or it might come to get me
My favorite number is .. 2. For the number of hours I spent trying to recreate the bubble chart in Excel that I could create on R in less than 5 minutes using your tutorial. Go R!
13…for luck!
6.
My favorite number is one larger than your favorite number…
My favorite number is 13, it was the day I was born.
i :)
My favorite number is the Godel number of the Godel sentence.
4, then 42, and then maybe 24 in that order. So 4 is the favorite.
I’m in! Nice price!
I’m learning R, and I’ve never formally owned a computing book.
I’ve never learned how to read a calendar either. So why did this show up on my FB feed today?
18!
10!
I’ve never won anything like this, but will give it a try anyway.
3’s my favorite #!
e
because e^(i*pi) + 1 = 0 (Euler’s formula)
My wife is learning R for her studies in Forensic Science. If I can get this book for her, it will help bring criminals to justice!
p.s. Her favorite number is 3, but mine is irrational

definitely 12. I don’t know why humans are so fascinated with it, but I guess it’s universal cause I am too
Seven, because it makes a filled hexagon.
Favorite number is 15. It just seems like a nice level-headed kind of a number.
My favorite number is 0.00000001. Why –because this is the ding-ding-ding p-value for GWAS..
17 – the least random of the random numbers!
88
42 is so old fashioned… but then, so am I. OK, 42 it is!
Interesting that only one other commenter found that March/May typo (or at least I hope it was a typo!) interesting enough to comment on. Reminds me of something I read about somewhere else… Bananas! Oh wait, wrong forum…

The golden ratio obviously : 1.6180339887
Far more impressive than pi from a viz perspective.
i
but also: 1729 (it has a good story associated with it)
1/137 which is alpha, the atomic fine structure constant

5, because it’s may not march

Here is a simple log-log graph of the data http://i.imgur.com/aamGv.png
Because it is the arithmetic mean of comments above mine with less than 10 digits.

e!!
17, because it’s the Humbug’s answer to every question in _The Phantom Tollbooth_ and because it is the least random number (according to the Jargon File).

pi is my favorite number.
yummy indeed!

Did no one else notice that the post says to leave comments by Sunday *March* 8? I think the next year March 8 will be on a Sunday is 2015, so no rush.

I like it because if you visualize it, you see a snippet of an interference pattern peaking at the centre with 4. Also, not only is it a palindromic prime, but the sum of all primes before it and this number make a pandigital number! No other sum of continuous primes has this property! Much more interesting than your average rational!
The moar you know..
My favorite number is i.
12!
15 :)
My favorite number is the aesthetically pleasing (1+SQRT(5))/2
42: the answer to life the universe and everything http://goo.gl/j7PnT
My favorite number is Euler’s Number (e). It’s got so many nice properties. It’s easy to take derivatives and integrals of e^x. Euler’s number is the main part of the pdf of the exponential distribution, and is part of what makes the distribution so fancy (memoryless distributions, anyone?).
3,720 (to 1). The possibility of successfully navigating an asteroid field…
My favorite number is definitely two times pi (a quantity that is sometimes called tau). It’s useful in all kinds of statistical formulae, and its abbreviated form (6.28) makes for a great summer holiday: http://tauday.com/

8 but I’ll change it if I can get a book.
13 … may because I am not superstitious? Oh wait, maybe I am if I think I my just win an awesome book with it! :)
I’d have to say 17.
Zero. That’s it–zero.
14.. because it was julie foudy’s number. also jerseys for high school teams are usually numbered by size – so there’s no way I would fit into no. 7.
42, nach.
Nice book. My favourite number is 13.
313
0
why? because it has unique characteristics: no effect on addition and subtraction, reduce to zero any number multiplied by zero, you can’t divide by zero, log(0) ~= negative infinity… zero is a badass number!
e^i
1/phi because the digits after the decimal are the same as phi, the Golden Ratio. It’s the same as phi^2, but I choose 1/phi because I really want the R Cookbook. We have a lot of cookbooks that we don’t use, I think I could learn a lot from this one, even if it doesn’t have a cupcake recipe.
11
Wow. People know numbers. Now I regret not paying attention in my math classes..
I’ll go with.. INFINITY (∞).

I’m torn between 0 and 42

I am a fan of 2.

9 works for me
$\phi$, she shur is purdy
1989, the year the best decade EVER started to end.

By the way I think the date is wrong, shouldn’t it be May 8?
My favorite number is 7. Not too original, I know!
7
I nominate 40.
43 .. cause if 42 is currently the answer, 42+1 is the next logical step in the evolution of life, the universe and everything
Phi, because
Phi – 1 = 1 / Phi
is just about the coolest relationship ever.
…Although 6 is a pretty ballin’ number, for an integer…

5 is the 1. The heck it is. :)
its 7/19 for me…….

A very interesting story involving two prominent Mathematicians, and dramatised by Complicite theatre company.

7 first, but others chose lucky 7
I want some R enlightenment
=)
3.5
16 – it’s always been a special number to me because it has so many different facets. It’s the fourth non-zero perfect square. It’s 2^4 -and- 4^2. 1+6 = 7, another lucky number. It’s also my birthday, and that’s four cool things about it times my square personality, which makes 16 – again.
70
37
It is obvious. My favorite number, an indeed almost everyone’s favorite number is 10. It is the basis of the decimal system and the metric system. Its fantastic. Now if only we could convince birthright Americans that 10 was a really nice number. They tend to prefer numbers such as 12 and 16.
12407 – It’s the first uninteresting number!! The smallest integer that does not appear in the Online Encyclopaedia of Integer Sequences :)
9B (or 9*10^9)
The estimated population in 2050… if we get there.
3 it’s a magic number
not sure if this is within the deadline… :)
anyway, my favourite number today is: 49
happy R cooking everyone!
338 works for me
e because pi gets all the attention.
3…if it works for 2, it may or may not work for 3…but it it works for 3, it will work for 4 or more (generally true in mathematics and programming)
14 !! what a number!
The answer is 42.

42, naturally.

My favorite number is 10, today. For the midfield maestro in me.
27, and I don’t know why. Whenever I have to come up with a number to use as an example, I use 27.
666
Because it confounds a certain sector of the Right Wing
