 # Search for your name in e!

### News Flash! Now searching 27,182,818 base 27 digits!! Tell your friends!

(Psst! You may also want to search for your name in the digits of pi)

### How can my name be in e?

I converted e to base 27 (if you don't know what that means, read the section What does base 27 mean below). I took the digits to represent letters, according to 1=A, 2=B, and so on. The digit 0 is punctuation.

In this way, the expansion of e looks like a long string of letters (with occasional punctuation), namely

 e = B.SJPY... = B + S 27 + J 272 + P 273 + Y 274 + ...
where A=1, B=2, C=3,..., Z=26.

### How many digits of e do you have?

I have over 27,000,000 digits in base 27. This represents the same accuracy as 40,000,000 decimal digits. If that sounds like a lot, it still only gives a 85% chance of finding a given 5 letter name! If your name has 6 letters, I'm sorry but the chance is only about 7%! And 7 letters? Less than 0.25%. Four letter names have a much better chance. I would be very surprised if someone typed in a 3 or 4 letter name and didn't find it! Please let me know if this happens! Most occur dozens of times, in fact.

### Why did you choose base 27 and not 26?

Base 27 is the neatest way which allows me to represent the digit 1 as A, 2 as B, ..., and 26 as Z. With Base 26, I would have to use A=0, B=1, etc... or A=1, B=2, ..., Y=25, Z=0. I think my system is the prettiest. If you don't like it, you can always set up your own search page... :-)

### How did you get the digits?

I wrote a program in java that added up the series e = 1 + 1 + 1/2! + 1/3! + 1/4! + ... in base 27, to a few hundred thousand terms (enough to get the accuracy I want). It took about 6 months to run. Ouch!

### Why did you do it?

Do I need a reason?? :-)

### Interesting e facts

Here are some interesting features of this way to represent e.
• The first animal: The first animal is the OX, at the 859th place. But there is a CAAAAT at position 266, followed shortly by a latin mouse...
• The first country: The Middle Eastern country IRAN, population about 70 million, is the first, coming in at position 107018. Abbreviations like UK don't count!
• The first name: At the 244th place, the first name in e is MOE. Unless Dez, Jed, Tzu, Tituz or Sjpyk are names...
• The first number: E appears in the seventh place after the decimal. If you insist on whole numbers, the first is ONE, at the 895th position. But then, you've always known that ONE was the first number, didn't you...
• The first ordinal: The first - it had to be, really - is FIRST, appearing at the 687342nd place of e
• The first book of the Bible: Coming in at the 5953rd position is JOB, the story of thesuffering of a righteous man.
• The first planet: The first planet is the fourth - MARS appears at the 864650th place of e. Admittedly, the competition from the other planets is not strong.
• The first chemical element: TIN is first (at the 15408th place), beating LEAD to the lead by 19476 places. Actually, I didn't check them all. If you find a closer one, let me know.
• The first English word in e is AT, at the 24th place. Well, I suppose that means the English word A also appears at the 24th place, doesn't it?

### What does "base 27" mean?

Many people know that e, the base of the natural logarithm, 2.71828... This actually means that
 e = 2 + 7 10 + 1 102 + 8 103 + 2 104 + 8 105 + ...
Because the number "10" keeps appearing in the denominator, we say this is e in "base 10". It is also why we have 10 different digits.

There is no reason why we have to use 10, however. The ancient Babylonians used 60 different digits! Even today, computer scientists sometimes use base 16 (with 16 digits 0 to 9 and A to F), base 8 (with digits 0 to 7) or even base 2 (with only two digits 0 and 1!).

If we were using base 16, we would say e was 2.B7E15..., meaning

 e = 2 + B 16 + 7 162 + E 163 + 1 164 + 5 165 + ...
here, the "B" represents the "digit" 11, and the "E" represents 14. In base 16, there are 16 digits, usually represented as 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E and F.

I wanted people to be able to look for their name in e. The alphabet has 26 letters, and it would be nice if A was 1, B was 2, C was 3 and so on. But there has to be a zero digit! So I decided to work out e in "base 27", with the 27 digits 0,A,B,C,...,Y and Z.

That's how your name can be in e!
