What do you love about zero?

My favorite number is 0. I have many reasons for this, but I want more.

Does anyone have any good stories, proofs, quotations, etc. involving this beautiful, dangerous, and intriguing number?

I like ballplayers who wear 0 or 00 as uniform numbers.

0 is like Switzerland.

Zero is neither positive nor negative.

Zero is so powerful that it turns anything multiplied by it into itself. That's so powerful there isn't even a word for it, unless you're some kind of math geek or German or something.

I love how mathematics' four greatest values, e, π, i, and 1, unite to form...0:

e^(πi) - 1 = 0

It has lots of names and nicknames: zip, nada, null, nullo, love (from tennis), the big egg, etc. You couldn't argue that, say, 27 has as many nicknames.

Zero is so powerful that it turns anything multiplied by it into itself. Similarly, zero can not be divided. Its role as a divisor, however, leads to fun mathematical fallacies and spurious proofs. For example:

3*0 = 0 and
7*0 = 0 therefore
3*0 = 7*0 and so divide each side by zero to reduce this equation to:
3=7

I also like the idioms "patient zero" and ground zero."

e^(πi) - 1 = 0
Actually, it's -2. e^(πi) + 1 = 0

The center of the 0 is filled with the possibility that can only come from emptiness.

"Zero: The Biography of a Dangerous Idea" is one of my all time favorite books...should have mentioned that!

Another book, mainly about the origin of 0: The Nothing That Is: A Natural History of Zero

Appending a zero to any number multiplies it by ten (1, 10, 100, 1000, etc.), but prepending it to any number does not change it at all (1, 01, 001, etc.).

Also, you can be saved by zero.

Zero's Wikipedia page might be a good place to start.

Maybe you would also like the coolest Wikipedia category.

My favorite zero-related riddle/joke:

What did 0 say to 8?

"Nice belt"

Zero is not a number. Neither is one.

A number is a collection of units. Numbers are often very different from each other, but they are of an entirely different order and class from nothing (which we name "zero") and from unit itself (which we term "one").

You might think I'm nuts, but Euclid agrees with me.

Certainly it makes sense to have no reasons.

I suppose it could be argued that it is the only number for which every number is a factor.

I'm particularly fond of 0/0, 0^0, and any indeterminate form. It's a nice little way of calculus telling you, "That's not gonna work. Try something else."

Dear Kevin S,
Probably the best response I ever could have imagined.

Although in mathematics you can't divide by zero, in most SQL implementations, NULL / 0 is defined, and equals NULL.

There's Schoolhouse Rock's "My Hero Zero".

Thank you, NoraCharles.

I can't believe it took 33 answers to get to The Schoolhouse Rock.

Here is a kind of trippy but awesome version of the Lemonheads doing a cover of the tune.

Like black, zero is defined by lacking that which it is categorized with (color and value respectively). Lots of people's favorite color is black.

If two values are equal, this means the difference between them is equal to zero. This can be applied figuratively: if you support gender / racial equality, you argue that there should be zero difference in how members of different groups are treated. Put another way: if two things are alike in every respect, they are unalike in zero respects. Zero thus represents everything and nothing simultaneously.

By not being defined as either an even or an odd number for the purposes of roulette, 0 and 00 modify the odds such that the house has a distinct advantage over every player (that is to say, the odds of landing on any one number are 37 to 1 while the payout is 35 to 1. That tiny difference is why casinos are rich and you're not).

Culturally, we rarely respect people who have success seemingly without trying, but instead admire those who achieve through hard work and determination. Without initial failure or humble beginnings, the ultimate success is without cultural value. In this way, the expression "from zero to hero" represents the pinnacle of all human achievement.

My favorite number is 0.

Actually everyone's favourite number is 0. Proof follows...

X says "my favourite number is 8".
==> "Nothing is more appealing than 8."
==> "0 is more appealing than 8."
==> 0 is X's favourite number
