Comment to win a signed copy of Data Points

Data Points: Visualization that Means SomethingIt seems like ages since we ran one of these.

It’s hard to believe Data Points hit the shelves two months ago. (Thank you to everyone who got a copy!) It still feels brand new in my head. I kind of thought that time would slow down after I finished the book (and dissertation), but it seems to be moving even faster now.

Anyways, if you’d like a chance to win a copy of Data Points blemished by my signature, leave a comment below by Wednesday, June 5, 2013 11:59pm PST. Tell us what your favorite number is and why. One entry per person please. I’ll pick a winner at random via sample() in R. Good luck.

And of course, if you can’t wait, have never been lucky at cards, or want a blemish-free version of the book, you can get it at online and physical bookstores everywhere.


  • Favorite # = 17. Why? Ever since I’ve been little, I’ve thought of mint every time I hear or see the number 17… Don’t ask how that happens, it just does. The brain works in odd ways!

  • Neat :). My favourite number is 113, a nice prime number.

  • 42 (Douglas Adams fan)

  • My favorite number is 42 because it’s the answer to life, the universe, and everything.

  • Nice

  • Erik Englund June 4, 2013 at 4:59 am

    42 – for obvious reasons

  • Patrick Hart June 4, 2013 at 5:01 am

    You can’t beat Pi. It’s just delicious.

  • Patrik Törmänen June 4, 2013 at 5:01 am

    My favorite number is 8 because it has no loose ends!

    Finished your first book a while ago so would love to continue the reading!

  • J. Dolberg June 4, 2013 at 5:02 am


  • My fav number is 13, because it looks so nice. :-)

  • John Kapson June 4, 2013 at 5:03 am

    Who doesn’t love pi?

  • 10, for the decimal system of units

  • Annie Chas June 4, 2013 at 5:05 am

    7. It doesn’t seem to fit anywhere. I guess that’s why people have been fascinated by it and attributed mystic powers through history..

  • Chris Fauske June 4, 2013 at 5:06 am

    One. It was the first number I learned.

  • 89 because when your slide deck has that many slides it makes you look smarter than you are.

  • My old jersey number: 4.

  • 42, it is the answer to the Ultimate Question of Life, The Universe, and Everything (or 7 which is my other favourite number)

  • 13, while it is unlucky for most, it has done some wonders for me.

  • Doug Cornelius June 4, 2013 at 5:11 am

    Three is the magic number. And the first schoolhouse rock song.

  • My favorite number is zero. This number is so rogue that is has multiple cool slang names for itself: Zilch, Nada, Zip, Big fat nothing, etc. I just heard about your Data Points book, Nathan. Good luck with it!

  • My favorite number is 135 because that is what round(rnorm(1,100,50),0) told me.

  • 49 – that’s my house number.

  • My favorite number is Euler’s number, ~2.72. It’s at least as prolific as Pi, appearing in pretty much every field of math at some level, but it doesn’t get nearly the same recognition (ever celebrated e-day? ever heard of someone memorizing e to 100 digits?)

  • I would have to go with 42, for reasons that should be farily obvious. Seems I’m the first one to leave a comment! Too bad that won’t help my chances!

  • Favorite number is 7 for my favorite baseball player Greg Gagne.

  • 25 – my bday is 5/25, so I’ve always liked squares of primes.

  • Hi Nathan,

    I’m an art director in Cape Town. Your book looks amazing!

  • r.e. spondent June 4, 2013 at 5:32 am

    9: It was used by in a Dilbert cartoon describing their random number generator

  • My favorite number is 3 because saying “three” forces you to smile.

  • Nick Jones June 4, 2013 at 5:33 am

    Yes, I’d really enjoy a copy!

  • Gösta Jonasson June 4, 2013 at 5:38 am

    19, Born the 19/9 living in a house with address 119.

  • 53 is my favorite number.

    It is a prime (also a Eisenstein prime). The sum of the first 53 primes is 5830, which is divisible by 53.
    53 can not be expressed as the sum of any integer and its base 10 digits, making 53 a self number.
    53 is the smallest prime number that does not divide the order of any sporadic group.

  • Favorite number: 26
    It is perfectly positioned between a square number (25=5^2) and a cube number (27=3^3).

  • Mário Cordeiro June 4, 2013 at 5:48 am

    1977, first because it is my birth year and second because 77 was a declared a A classic Vintage port wine year:

    By the way, the book is great. Let’s see if it ages like the 1977 port wine and deserves to be declared a “vintage” book in the area of visualization in a couple of years.

  • e (2.718281828) because it is its own derivative. So cool!

  • 333

    • because it´s was my house number, and it somehow shows up randomly in my life routine.

  • My favorite number is 4, because it is near the 3 but not as mainstream as the 3 ;-)

  • Rajay Teraiya June 4, 2013 at 5:56 am

    My favorite number is 73. Go Chuck Norris! (Reference: Sheldon from Big bang theory)

  • 1. Because I’d like to be the ‘one’ that wins the signed copy of your book.

  • My favorite number is 27 –> 3ˆ3

  • My favorite number is 2. And I would love to win the book! :)

  • 23- seems to pop up a lot and be a common birthday among family and friends.

  • Anne-Laure June 4, 2013 at 6:04 am

    I like 13 because of a family story… My great-grandmother used to tell me that when she was little they began putting numbers on the house in her street and nobody wanted the number 13. Her mother volunteered. For 90 years (except for the war) it was a very happy house.

  • My favorite number is 37, but eleventy billion is a close second. There’s something inherently funny about 37.

  • I love 11 because it looks so nice on a 7 segment display and 11:11 is my wishing time.

  • 583,089
    … because that’s the number R gave when I asked for a random number between 0 and 1 million. However, when I went back to check my work, R gave me an entirely different number. I think R is broken. Ha!

  • 10 – It’s a family tradition that every sports jersey worn in competition by anyone in my family (aunts, uncles, cousins, siblings, etc.) is some combination of numbers (73,64,82,19,etc.) that add up to 10.

  • 29. It was my laundry number in Marine Corps boot camp, and again later at Officer Candidate School, and it has been in every phone number I have had since circa 1990 (four different phone numbers).

  • 11 because it is a fun prime. Also like 3 because it is 11 in base 2.

    Visualize This is the most grabbed book by people visiting my cube. Looking forward to more ideas from your next book!

  • Zach King June 4, 2013 at 6:20 am

    I like Pi because it is important to a great many calculations.

  • 8 is my favorite number because it’s so, symmetrical. Thanks for the contest!

  • Sean Parmelee June 4, 2013 at 6:22 am

    Mine is 11. It was my number in soccer & volleyball, plus my amps go to 11.

  • Joao Beno June 4, 2013 at 6:22 am

    13, Because a lot of people seems to dislike it…

  • Favorite number is 8. Has been so from a young age and my best explanation is that I like the aesthetic symmetry when placed on uniforms in football and basketball. A disproportionate number of my favorite athletes wore that number. Loved your previous book Nathan and would of course love to win a copy of the new one.

  • Seven (7) – it’s a divine number, repeated over 250 times in scripture.

  • 17. After all I went to Hampshire College’s Summer Studies in Mathematics.
    The first occurrence of 17 in a mathematical table was incorrect!

  • I know it’s stereotypical, but pi. Beautiful!

  • 42 – It’s the answer; we just have to figure out the question. Preferably via planet-sized simulation (now THAT’S big data!)

  • Bill Morgan June 4, 2013 at 6:35 am

    37 – Our car number in a rallye crash which I survived.

  • Zero.. depending on ones views about it being a number or not

  • 88, it has visual symmetry and it’s good luck!

  • 13 – for its undeserved bad reputation.

  • 6 because it is Bert’s favorite number and it’s the first perfect number. I actually like Ernie better, but I couldn’t remember Ernie’s favorite number (8,243,721) as he said it too fast when I saw the segment on Sesame Street. It took me years to finally track it down.

  • 6 has been my favorite number since I was a kid and my dad told me about perfect numbers.

  • 1 = indivisible

  • Mine’s the same as Avagadro’s. It’d be nice to have a number named after yourself. He must have gotten a lot of pints bought for him at the pub after long hours chemistrizing.

  • My favourite numbers are 4, 8, 15, 16, 23 and 42. Do I need to say why? :P

  • My favorite number is -6943. That’s the SAS date of my sweet mother, RIP.

  • ^ sas birthdate, I should say

  • I’ve always been partial to 23. Seems to keep showing up everywhere…

  • 3 because I am mainstream.

  • Deeanna Antosh June 4, 2013 at 6:55 am

    7, a little cliche but it appears 3 times in my birth date and I weighed 7 pounds 7 ounces

  • Ricardo Sanchez June 4, 2013 at 6:55 am

    zero is pretty cool. i like the idea of representing nothing.

  • My favorite number is 47. It is the most common of all random numbers

  • Howard Yamaguchi June 4, 2013 at 7:00 am

    63 – I had (and still do) a childhood fascination with this number; maybe that the second digit was half of the first, among other things.

  • 24. It’s nicely divisible by 2, 3, 4, 6, 8 and 12.

  • My favourite number is 2 because it’s the only even prime.

  • 818 because it’s my birthday!

  • I’m going to have to go with e (2.718…). I has a tendency to keep showing up in a variety of mathematical fields and applications!

  • My favourite is 73 because it is a palindrome in both binary AND international Morse code. (Sheldon didn’t get the second part).

  • Christian June 4, 2013 at 7:17 am

    phi – 1.618… – the golden ratio – truth, beauty and goodness all wrapped in one nice little package

  • 10 – because its the foundation of our numerical system.

  • Current favorite number is 36. It changes every year though.

  • Matthew Hertz June 4, 2013 at 7:19 am

    0 because zero is my hero.

  • My favourite number is 1111 especially when it shows up on a clock. as 11:11. I always seem to catch sight of it and it makes me happy when I do.

  • Number 8. It has always been lucky for me.

  • 70 because its the smallest weird number

  • My lucky number 6.

  • 219 – When I was a child I won a Nintendo in a game with that number :)

  • Jason Francis June 4, 2013 at 7:31 am

    01189998819991197253. They’re not the emergency services, they’re your emergency services.

  • 23 – favourite Jimmy Eat World song

  • 14, because this is how many dimensions we live in, according to the new Geometric Unity theory of Eric Weinstein.

  • bill carrera June 4, 2013 at 7:40 am

    5 its the size of my family and biggest we can get before we have to buy a minivan. its the perfect number.

  • My favorite number is 56, because it was the hardest part of the multiplication table to remember, and it was a victory when I finally got it.

  • 2 – the only even prime number :)

  • My favorite number is 89, because I was born in 1989 and it’s showed up on a couple school ID numbers as well!

  • Matt Hofmann June 4, 2013 at 7:57 am

    34–Walter Payton!

  • 13. Such a sexy number…

  • 1 would be my favorite number..

    multiplied by itself, it stays the same
    divided by itself, it stays the same
    it also represents the “other part” of the binary system
    it’s also the atomic number for hydrogen, which makes your voice sound funny.
    it’s also a song/album by way too many bands to list here..
    it’s also the local service in nyc to get from lower manhattan to tha bronx

    and this post is 100% (1) done.

  • 23, because it was my baseball jersey number every year I played (before Michael Jordan made it popular).

  • Favorite numbers tend to shift for me, but my current favorite is tau, since tau day is less than a month away and I then I’ll get twice as much pi! :)

  • fav # = 3, simple, small, prime, odd. though 23 is a close second.

  • 42… Yup you what it is.

  • I love 70 – it’s the first weird number.

  • sqrt(2) – The first irrational number known.

  • One. It’s the loneliest number I ever did hear.

  • 6. My 6th sense told me so!

  • My favorite number is 27 because it was worn by favorite player when I was a kid.

  • 18. I am lame and chose to like it as a kid because my best friend liked the number 17. Doesn’t explain why I still like the number, just do :)

  • My favorite number is 8. On its side it is infinity.

  • 2^31 aka, 2,147,483,647
    in base 16: 0x7f ff ff ff

    The largest _signed_ integer on a 32 bit instruction set

  • James Ortega June 4, 2013 at 9:05 am

    Favorite Number: 17
    I’ve always like the look of it. It was also my Dad’s baseball number, my wife’s high school volleyball number, her dad’s football number. I’m just continuing the tradition I guess.

    I’m reading your first book, visualize this, it’s great. Would love to win the second one.

  • 5 – just like the way it sounds.

  • Rob Rolleston June 4, 2013 at 9:05 am

    i – “Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand” – Albert Einstein

  • 7 – For reasons I do not know.

  • 42. (2 x 21) 21 Was the “Great One” Roberto Clemente.

  • Gerardus Calcitrosus June 4, 2013 at 9:11 am

    i – I’m a complex guy

  • e – Euler’s Number – because it’s pi’s less appreciated cousin.

  • Canoehead June 4, 2013 at 9:14 am

    320! (the number of pages in the Data Points book I’m going to win!)

  • 16. 4^2 == 2^4 has some nice symmetry. And it’s when I could finally drive myself to school!

  • Joshua Muskovitz June 4, 2013 at 9:20 am

    “69, dudes!”
    Gotta love Bill and Ted.

  • 1 is the loneliest number, however, if I had Data Points to read I could multiply the number of friends and maybe make a duo!

  • 3… cuz is the magic number…

  • 2. It’s better than 1.

  • Greg Sjaardema June 4, 2013 at 9:26 am

    12.5 or ~pi^2. It was the multiplier needed in some early work I did on matching salt creep behavior with analytic results. We then needed to find out where this value came from…

  • Jonathan Perry June 4, 2013 at 9:26 am

    4 – it’s the numeric representation of my most frequently occurring utterance while golfing.

  • HealthStatsDude June 4, 2013 at 9:27 am

    Never been lucky at cards (too many tells) but I’ll give this drawing a shot anyway!

    18–Payton Manning’s jersey number. Yeah, not very geeky (looking at you, susan silver!), but what can I say–I’ve been a Broncos fan since I was a wee lad in the 1970s.

    Zero’s close second, though, mostly cause of Seife’s book on the subject. And, as you know very well, books are POWERFUL! (So keep ’em coming, Nathan!)

  • JonnyHope June 4, 2013 at 9:27 am

    Got to be 6, its perfect, real, great all rounder, fabulous curves

  • Stephanie W June 4, 2013 at 9:28 am

    6036. Is the sum of all the birthdays in our house and is our daughter’s birthday backwards.

  • 1
    is not the loneliest number
    it’s true

  • Marc Fernandes June 4, 2013 at 9:32 am

    Favorite number is 6 for a variety of reasons.

  • My favourite number is 2 — I was born 2/22!

  • 42 because I am a nerd and unoriginal. :P

  • Mano Senaratne June 4, 2013 at 9:36 am

    My favorite number is 13; despite the myths, I have found this number to be lucky for me. After all my name has 13 letters :-)

  • 137 – For some years, physicists thought that the ‘fine structure constant’, a dimensionless ratio expressing the strength of electromagnetic interaction, was exactly the reciprocal of 137; this imbued the number with near-mythic significance, and a entire book was written about the magical properties of this special number. With further research, the ratio was determined to close to, but not exactly 1/137, so the number lost some of its sheen. A metaphor for so much of life.

  • My favorite number is googleplex ( A google just isn’t large enough.

    A close second is the number one, because one is the loneliest number that you’ll ever do.

  • Until recently I would have said 42, but my new wife and I chose a series of prime numbers for our wedding: 2/23/13. So recently 23 has come to the fore as the number I favor.

  • 0. For nothing (pun intended)

  • 8, it’s fashionable i.e. Q: ” What did the zero say to the eight? ” A: ” Nice belt. “

  • Paul Wiegand June 4, 2013 at 9:46 am

    As a computer scientist, I have to be prosaic and suggest that the number 2 is the best. It is the only even numbered prime, also a power of two, and the smallest base in which numeric information can be encoded. Spelled in English, it also has two homonyms (to and too). When displayed on your hand in the traditional way, it also doubles for the symbol for peace and can be held over people’s heads to make them look silly in photographs. Clearly there are only two categories of numbers: 2 and everything else.

  • Alessandro Gagliardi June 4, 2013 at 9:49 am

    I’m not sure if it counts as a number, but my favorite numerical expression is 0/0 because 0 over anything is 0, but anything over itself is 1, and anything over 0 is infinity (or undefined, depending on your religion). It’s like a zen koan expressed in a number.

  • e . . . its just so natural

  • It’s silly, but I’m going with 45,954 – my pubescent, middle school self was very excited when it realized the product of 69 and 666 is a palindrome. The irreverent, immature, and oh-so-nerdy nostalgia that number elicits for me captures the essence of those years perfectly.

  • I’d love to win another copy so I can finish reading it. So far, 6 of my collegues have “borrowed” mine before returning it saying they have purchased thier own copy. Collegues #6 is a slow reader….

  • 24. It just hits a great balance between a high number of factors, making it easy to do arithmetic in modulo, with its relatively low numerical value. The sum of its factors is 57, so the ratio to itself is almost 2.4!

  • Gwyndolyn June 4, 2013 at 9:56 am

    My favorite # is 2. First is the worst, second is the best, third is the one with the hairy chest.

  • It’s already been picked, but 24 for the same reason.

  • Gosh, I totally messed that one up! I forgot 3! The sum of 24’s factors is 60, so the ratio is 2.5. Even better!

  • 9 because it has absolute symmetry by 3.

  • 42. For life, the universe, and everything.

  • 2 is my favorite!

  • My favorite number is 7 – I don’t know why, it’s just what’s stuck with me since I was a kid.

  • 17. It’s prime, part of a prime pair (w/19). And it was a lovely age, too. :)

  • 27. for me, no pair of numerals looks as pretty set non-lining.

  • 121…because it’s 11×11 and builds to all of the other 11 multiples in its cool way. (okay…probably *really* 42, but that would just look too much like following the crowd).

  • Favorite number is 3. Everything can be measured with the number 3.

  • 6 is my new favorite number since that is the month that will play host to the birthdate of my expectant little one. :)

  • 3 – because Schoolhouse Rock says 3 is a magic number.

  • 86400, the number of seconds in a day. Pops up all the time in hydrology and hydrogeology (as well as many other disciplines, I presume).

  • My favorite number is 9 because I’m Life Path Number 9. I know, it’s pretty naive. ;)

  • My favorite number is .618

    I use the golden ratio at work everyday!

  • 10 – the best number that makes measurements easy!

  • 3,141592653589793 because it’s magic

  • i like 5; always have. It’s so useful “let’s take 5.” “High five” etc.

  • e, but not for any rational reason.

  • 16384 – The first power of two that I have to calculate–too many syllables to memorize.

  • A googol. (I remember now being able to find because I misunderstood a friend in school.)

  • Well, since 42 is already taken… how about 2.7182818284590452353602874713526624977572470936999595…

  • 525,600 — number of minutes in a year, part of the lyrics from one of the songs from Rent

  • Jared G. West June 4, 2013 at 11:27 am

    I like Moser’s Number – for no other reason than I looked it up and no one has claimed it as their favorite number yet.

  • 8, because it seems to coincidentally pop up in several significant dates in my life.

  • I like 1729, because I still remember the story I read about Ramanujan, upon hearing that his friend Hardy had ridden in a taxi with that number said, “it is the smallest number expressible as the sum of two cubes in two different ways.” I never cease to be amazed by a mind that could work like that.

  • 2. I don’t remember how I started liking it but it’s been my favorite since I was a child.

  • 21, because that’s how old I am. In hexadecimal.

  • 27 is a good number. Hard to pick just one favorite with so many good choices.

  • 0. It’s modern as far as numbers go, is easy to multiply yet hard to divide, and doesn’t take up much space.

  • I learned a lot from the first book. Looking forward to this one!

  • 7. No idea why, but it works for me!

  • 6 – I was number 6 at my elementary theater show :)

  • 33 just because

  • Either 42 for obvious reasons or e^pi i + 1 since it’s the average of all numbers in the universe.

  • Fibonacci sequence: 11235813

  • 13. I was born on the 13th, and always liked the fact that a lot of people think it is unlucky.

  • Neil Bowers June 4, 2013 at 12:31 pm

    87110: my zip code from a very enjoyable 3.5 years spent living in Albuquerque.

  • 1024 – that’s 1 followed by 10 zeroes

  • One, because it means the same in any base.

  • fav number: e
    why?: it’s everywhere!

  • 17, i’ve just always liked it. it used to be 7 but the 1 just kind of slipped in front of it i guess. It is also the least random number.

  • My fav number is pi: 3.14159…especially on pi day (3/14/YYYY) – and pi day in ’15 should be extra special!!!

  • 2, you and somebody else :)

  • Drew Daniel June 4, 2013 at 1:26 pm

    3 – because my dad use to take me to the horse tracks as a kid and we would always put a WPS on the 3.

  • 13 just because all good things happen to me either on 4th (1+3) or the 13th.

  • Shawn Freeman June 4, 2013 at 1:32 pm

    Well, 42 is my first choice, for obvious reasons. Since that is over-represented here, I will take my second choice of 25.

    Why? Because I spent two years being “25 years old”. Strangely (or not), I often do not remember my age off hand. I have to calculate it from my birthday. Sometimes, when under the pressure of a doctor checking that you don’t have some mental damage, the calculation fails (or failed in this case). The rest is history.


  • My favorite is 9, because for me, it is shaped like the word “dream” appears in my head. Seems like a particular kind of synesthesia somehow. But the number just feels nice, warm and cozy.

  • Nick McClure June 4, 2013 at 1:44 pm

    22/7 = 3.142857. An easy real world approximation to Pi.

  • I am a Pi day boy, so it is Pi of course :)

  • 7 because it means perfection! :)

  • 8,589,869,056. It is the 6th perfect number. Or, it is the first perfect perfect number.

  • 37

    Many interesting things…
    All three-digit repdigit numbers are divisible by 37 (e.g., 111, 222, 333, …)
    pi(37) = 12, pi(73) = 21.

  • 11. It’s lucky.

  • Peter McMenamin June 4, 2013 at 2:45 pm

    My favorite is 789, because we all know why 6 is afraid of 7.

  • Joseph Brew June 4, 2013 at 2:51 pm

    26. Cause that´s the number you´re gonna pick, and I want this book.

  • 17!
    My 3rd grade teacher numbered our desks and would pull numbers to do fun jobs. I loved clapping erasers outside. :) 17 was my desk number.

  • 97, the highest two digit prime.

  • 200 for HTML okay and making my life easy (for that particular moment)

  • X because it is unknown (or roman numeral 10 if you want to get pedantic)

  • 1729, ramanujan remarked it was the smallest sum of 2 cubes in 2 ways

  • 25. Always liked it.

    5 because that’s how much lunch should cost

  • Chris Hogg, VP of Data Sciences at Practice Fusion, if another one of my data-nerd heroes.

  • 203 – my birthday falls on the 23rd of March, and 203 was my high school locker number!

  • Hard to choose between 1 and 0. Pi and e are cool to, but you gotta love 1 for its completeness. 0 is for the cynics! ;-)

  • 42 is the answer.

  • 14.

    – It’s 7×2. My birthday is on the 21st, which is 7×3 (July 21). July is the 7th month of the year. Halfway between 7 and 21 is 14. 7 is a cool number, which makes all of that cool.
    – It’s the day I started my job, which is where I learned about big data and visualization (July 14)
    – It’s the day I’ll marry the love of my live (October 14)
    – It’s my sister’s birthday (September 14)
    – It’s Bastille Day (July 14)

  • 699998. Its the smallest positive uninteresting number.

  • 2006, the year I got married.

  • Naughty. Number. Nine.

  • 37 – I was born on the seventh minute of the seventh day of the seventh month. 12:07 am, July 7th. So three sevens.

  • 25, because it is 1/4 of 100

  • Lucky number 7 was the first number that popped into my head. The Perfect Number.

  • 4. birth date.

  • 42 is the best number, of course!

  • Barbara Chatzkel June 4, 2013 at 8:21 pm

    5292 – My husband’s name on a key pad.

  • Mark Emmett June 4, 2013 at 8:34 pm

    My initial is ‘M’, which is the 13th letter of the alphabet, so 13 always been my favourite number.

  • 5, it’s my birthday

  • Pam Brown June 4, 2013 at 9:41 pm

    13 – some consider it unlucky but not I. It is my birthday when cake soon follows….

  • 2000, Knight Industries Two Thousand. Need I say more.

  • Phi – the golden ratio – 1.618. Because it is everywhere – pinecones, pineapples, sunflowers, trilobites, the solar system, our body, … The list goes on and on.

  • My favorite number is 10 because that’s as high as I can count using my fingers.

  • 39072

    Because it’s the value to use with set.seed() in order for sample() to select this comment.

  • My favourite number is 33 and always has been. It has a certain equilibrium to it. My brother’s favourite number is 32 and we always had long discussions about which number occurs more. 32 being 2 to the 5th, it appears often in relation to computers (e.g. when 32MB RAM was a big deal), while 33 is a third of a 100 and appears on soda cans and beer bottles (33cl). Of course, once those two numbers are on your mind, you start seeing them everywhere!

  • 2. As a Computer Scientist we always break information into a series of states consisting of on and off.

  • My favorite number is 0.
    0 represents continuity (10 after 9, 100 after 99, 1000 after 999).
    0 represents completeness (no number system is complete w/o 0).

  • 4: my daughter, my son, my wife and me :)

  • 0: I like how is written!

  • Andy McKeown June 5, 2013 at 12:56 am

    1440. It’s when Countdown used to start.

  • Philip Keogh June 5, 2013 at 1:03 am

    Number one, because, as my wife keeps telling me, it’s all about me!

  • 23 b/c it’s my birthday!

  • 23. Because of conspiracy theory.

  • 3, I like the shape, I like to write it in various manners, and it bizarrely comes back many time in my family birth dates…

  • 19. No real reason why!

  • 7, always loved it

  • 6 it is the 1st perfect number

  • Adam Doherty June 5, 2013 at 4:02 am


  • 8 – because I like circles.

  • Ken Levasseur June 5, 2013 at 4:31 am

    The golden ratio, (1+sqrt(5))/2.

  • > sample(1:100, 1)
    [1] 2

    So I guess my pick is number 2…

    Go #2!

  • 21, that has been my lucky number :)

  • Favourite number = 8790

  • 4. I tend to see numbers as physical representations, and 4 is this 3D 4-pointed star shape that I seem to have more of an affinity for.

  • 3600 – The number of seconds in an hour (and a nice square number).

  • Has anyone picked 216 yet?

    That’s a good one. Untouchable. Sum of a twin prime. The smallest cube that’s the sum of three other cubes. And it’s apparently a “Friedman” number, whatever the heck that is.

    But it’s best-known to me (and my fellow web old-timers) as the number of colors in the “web-safe” color palette.

    And it just has a nice ring to it, don’t you think?

  • 6.28… Support Tau (abolish pi)

  • Tarcízio Silva June 5, 2013 at 7:53 am

    34! It’s the number of the Magic Square of Albrecht Duhrer, my first tattoo. =)

  • 9 – the largest single digit plus see all John Lennon references.

  • 8 – even, balanced, divisible numerically.

  • 13 – because it’s a odd number

  • 2.71828 because I’m irrational

  • Ed Gilbert June 5, 2013 at 9:15 am

    6. I deny having a favorite number now, but 6 was my favorite number when I was a kid. I don’t know why.

  • Kevin Shipman June 5, 2013 at 9:24 am

    7. It’s ‘lucky’, always comes up in dice and life.

  • Brett Kleinschmidt June 5, 2013 at 9:36 am

    aleph-naught — the source of a sort of enlightenment for me in university.

  • 10.
    Because it’s the biggest number I could think of.

  • 3 because it’s been my favorite number since childhood. And it’s prime.

  • 44 – Mr. October’s number

  • My favourite number is 8 – I think I like the shape of it. And my birthday is in August.

  • 2: i like being together with my girlfriend..

  • 13 – birthday number and b/c people are so superstitious about it.

  • 323 – birthday of my son

  • Mine is 11. I was born in 11-11, it was my basketball number, I was 11 years old (loooong time ago), and a couple more of 11-related stories :)

  • 7 – It’s lucky!

  • Mine is 7, because it is the day of my birthday and because it has “magical” or “mystical” meaning. Good luck!!!

  • My favorite is 0. It is the beginning of everything.

  • 73 – its a star number so you can make a six pointed star from 73 dots. It is also an emirp number, a pallindrome when converted to binary 1001001. Amazingly the binary consists of seven digits and three 1’s – nice. It also describes something rare and blue in chemistry – it is the atomic number of Tantalum. Plenty of attachment to the visual world in the number 73, so let’s go for that.

  • i. Blew my mind when I found out the “imaginary numbers” Hobbes told Calvin he needed to use for his 1st grade homework problem of 9 + 4 was a real thing. Tigers are good at mass (and/or they’re jerks.)

  • Alex Yakubovich June 5, 2013 at 11:53 am

    2 – because it’s so fundamental to math and computer science.

  • Eugene Evon June 5, 2013 at 12:22 pm

    ∏ Pi. I’ve had it memorized to this many digits since 1976

  • “∞”
    ∞ because there are ∞ possibilities!

  • I’m with the other Paul who likes Euler’s number. Why:
    o Natural log of e = 1
    o Sum of an infinite series 1/1 + 1/(1)(2) + 1/(1)(2)(3) + … = e
    o derivative of e^x = e^x

  • THIRTEEN, as in thirteen dancing vegetables. Or, if you are feeling lucky then SEVEN, as in seven coconut cream pies.

  • Got to be e^pi*i +1, AKA zero.

  • Claudia Alcala June 5, 2013 at 1:16 pm

    My favorite number is 7, besides its symbolic meaning, I think it is the easiest number to write.

  • 0 – it’s unpretentious.

  • 1 because its the loneliest number. 2 can be as bad as 1, but 1’s the loneliest number ever done

  • I like 3, because I find myself linked with it always.

  • Must be 4. . . just because.

  • David Lowe June 5, 2013 at 2:15 pm

    Not sure why, but
    6.022 141 29 x 1023 mol-1
    always makes me hungry for guacamole. I’ll have mine very garlicky, please.

  • Tor Bertin June 5, 2013 at 3:32 pm

    Boringly, and commonly, 42.

  • Zero. Without it, numbers would only be useful for counting.

  • 80085 because it’s what every boy typed into their first calculator among friends.

  • Gil Gilliam June 5, 2013 at 4:28 pm

    3.14 – it’s the only number you can eat.

  • Ulrike Bende-Michl June 5, 2013 at 4:39 pm

    wow – I just like the book!!! Since I am a geographer I like principles on spatial distribution – I’ll go for figure 3-16.

  • Steve Taylor June 5, 2013 at 4:56 pm

    4. When I was a kid I was obsessed with the number 3, which made tetrahedrons the most interesting 3d shape. Tetrahedrons have 4 vertices, so 4 is the most “3-like” number, even more so than 3.

  • 2976579765 – because it is so delicious in hexadecimal :)

  • Kenny Williams June 5, 2013 at 5:20 pm

    Nathan, I will go with 6520131159 to honor the date and time this number must be received for validation…thanks!

  • The number 164 has always been a favorable choice, due to its resemblance to famed boxer Lupé Brommix.

  • 3 is a magic number; but I think I prefer 11, because it’s the fifth prime, and 11 is three deeper than 5 in the prime list.

  • My fav number is 0 : It was the most dangerous idea which came to men!

  • 4815162342, but the meaning is lost…

  • 1014 – and my wife would be proud ;)

  • My favorite number is 4. It started out for rather silly reasons, but when I discovered that it was also my wife’s favorite number (10 years before we got married), it began to carry a new significance.

  • 7 – I’ve had several lucky experiences involving that number!

  • 36. It’s such a well rounded, talented number.

  • Comment left behind. Book right ahead.

  • 2517
    this is the number of the fake passage from the book of ezekiel that Jules in Pulp Fiction recites a couple of times. also it happens to be the zip code of a tiny village in Hungary. that is Kesztolc, my home.

  • 13, my lucky number :)

  • 23.
    My 23rd birthday fell on 13th October 2007, which is 13+10+2007=2030.
    13th October itself is 13+10=23.
    On that day, I took my friends for dinner,spending Rupees 3929. 3+9+2+9=23.
    A friend was wearing a tee on which “DEVIL” was written. 2/3=0.666 the devil’s number.
    Later that night, I and my date checked into a hotel. Room number 19D. D is the 4th letter of the alphabet. 19+4=23.
    Finally, at work, the project I was involved in was code named Vanadium. It’s atomic number is 23.

  • 21 – the sum is 3, it’s a miracle.

  • Dan Mandle June 6, 2013 at 5:05 am

    8. It’s the same if rotated 180 degrees. Spin it 90 degrees in either direction and it goes on forever. (Playing the position on my rugby team in college also helps!)

  • wei chong June 6, 2013 at 9:10 am

    7. It’s the best number for the first roll of the dice.
