So, having covered pi and e, we have the curious fact that



e^pi is called Gelfond's constant; nobody knows why it is nearly identical to pi+20 other than a crazy coincidence.
Another quite interesting constant is exp (π √163). Wolfram shows that
exp (π √163) = 262537412640768743.99999999999925007...

The quite interesting difference between the two is that (if memory serves) the latter is not considered so much of a coincidence: the reason is because when you express the value as an infinite sum, you get two large integer values (262537412640768000 & 744 or something) and everything thereafter is very, very small. Whereas e^pi -pi is just very coincidentally very close to 20.

The record for the largest known prime number has been broken, and it is a gimp.

The Great Internet Mersenne Prime Search (Gimps), as covered previously on QI, has found that the largest prime number now known is 2^74,207,281-1. It is 22,338,618 digits long.

if any natural number is multiplied by nine, and repeatedly add the digits of the answer until it is just one digit, the sum will be nine

4344563120409 (4 + 3 + 4 + 4 + 5 + 6 + 3 + 1 + 2 + 0 + 4 + 0 + 9 = 45; 4 + 5 = 9)

With all these definitions it is convenient to include 0 (corresponding to the empty set) as a natural number. Including 0 is now the common convention among set theorists and logicians.

0 * 9 = 0

Here is what I think is a quite interesting question connected to numbers and popular culture:

What's terrifying about Japanese number twos?

The answer is that it is very scary if it would be said by a bunch of knights from a Monty Python film, because the Japanese for the number two is "Ni".

Sorry, but are you talking about '2' or 'shit'?

The Japanese for "2" is "ni". The Japanese for "shit" is "kuso".

Clearly there is confusion, which is why I wrote the question like that, for the cheap laugh.

Since this is Japanese we're talking about, doesn't the word for shit depend on whether it's your feces or someone else's, and on the social standing and relationship to you of that someone else?

Yes indeed, and Japanese for the number 10,000 is "itchy man"*.

Which I find interesting if only because they have a unit (is that the right term?) equal to ten thousand. So for instance, 654000, which we think of as

6 hundred thousand,
54 thousand,

they think of as:

6 hundred thousand,
5 ten thousand,
4 thousand.

They also do time based on the speed at which the time unit ticks over. So

12:34 pm on the 5th August 2001

would be

2001 August 5 PM 12 hrs 34 mins.

(I think that's right.)


* well, 一万, which is transliterated as "ichi man"

At Tets' suggestion:

South African cricketers count like this:
1,2,3,4,5+0,6,7,8,9,10 etc

The shirt number 5 has officially been retired out of respect for Hansie Cronje. The chap using the number 5 at the time it was retired decided to go for 5+0 as his new shirt number.

(see cricket thread for my attempt at reasoning this out loud as it were)

I am now wondering at which point did English shit become 'holy'?

Before 1850.

Holy shit, Holy guacamole (first cited in Batman), Holy Moses, and all sorts of others are minced versions of Holy Christ, which was originally a genuine call for divine intervention.

The American buckthorn (Rhamnus purshiana) has several English names, one of which is Holy bark. It is used as a laxative, and was given that English name precisely because of what it led to ...
