You know when somebody says that something is "astronomically big"?
...well, it turns out astronomers use some pretty freakin' big numbers!! o_O
Anyway, I have collected the following series of numbers from Wolfram Alpha:
6.5 10^9 Number of people currently alive.
1.1 10^11 Number of people who have ever lived.
3 10^11 Number of stars in the Milky Way galaxy.
2 10^13 Number of red blood cells in an adult human.
10^21 Number of grains of sand on Earth (currently).
6.0 10^23 Number of atoms in 12 g of Carbon-12.
5.2 10^49 Number of possible chess positions.
8.1 10^53 Number of elements in The Monster Group.
10^80 Number of atoms in the observable universe.
I note there's quite a few gaps in there, so I turned to Wikipedia to
try to fill them. Check these out:
4.33 10^19 Number of valid combinations for a Rubik's Cube.
8 10^10 Number of galaxies in the universe.
5 10^22 Number of stars in the universe.
4 10^11 Number of stars in a "typical" galaxy.
10^57 Number of H atoms in a "typical" star.
4 10^68 Number of H atoms in a "typical" galaxy.
2 10^30 Kg Mass of a "typical" star.
4 10^41 Kg Mass of a "typical" galaxy.
3 10^52 Kg Mass of the observable universe (exluding Dark Matter).
So, there's a few numbers there.
With suitable queries, you can also get Wolfram Alpha to spit out the
following numbers:
8.8 10^26 m Diammeter of the observable universe.
4.32 10^17 s Age of the universe.
3 10^22 m^3 Volume of the observable universe.
These are harder to get though.
So far, I have yet to find anything outside mathematics that even
remotely approaches a googol.

Erm, no.
3 * 10^80 m^3
(Jesus, I wonder what else I got wrong?)

I think I can add another number to my list: How many pharmacutical
analysts does it take to do a 9 year old girl's school homework? :-P
(Seriously, these two ladies are confusing the stud out of themselves
with these long division problems...)

256^307200 Number of unique 8-bit 640x480 images.
Assuming flat greyscale, 0=black, 255=white, how many are recognisable
as 'something'? How many of those are similar apart from 'noise',
rotation, and other minor distortion? How many of those are legible
text? ...that are of a monkey at a typewriter that visibly contains a
phrase from Shakespeare? etc

Assuming bacteria is not unique to this planet how many bacteria inhabit the

I don't believe that number. I think if you add all people since the
last ice age you get someting like 10-20 e9. This number also seems to
assume that there have been on average .5-1 million people on this earth
for the past 2 million years or so (half that if you think mankind is 4
million years old). I'd like to see evidence for that.

I haven't any idea what this is. :-)

I wonder if they're just talking about rest mass or what.

What, Avagadro's number? (Or however the hell you spell it...)

Apparently, there's a class of groups which can be completely classified
into something like 6 different kinds, except for a small handful of
unique groups that don't fit this classification. The "monster group" is
the largest such - and it's frickin' HUGE!
Wait - you know what a group is, right?

I fail.

I'm fairly sure it's rest mass, yes. Basically, number of atoms times
mass of an atom.

Yes. You know why anyone cares about Avagadro's number? I.e., what the basic
thing it's measuring is?
> Wait - you know what a group is, right?
Vaguely. I'd have to look up the definition again to be sure I'm not
confusing it with a ring or field or something. My higher-level alegbra is
way old. :-)

No, it just means that either measurements are very sloppy, that "typical"
means something different in those sentences, or there's 10x times as much
mass in a galaxy as their is mass in the H atoms of the galaxy. Which isn't
completely impossible - see "giant black holes", "dark matter",
"relativity", etc.

Yeah. :-)

Number of atoms? (Or sometimes ions, or subatomic particles of some
kind. Make sure you specify; it kinda makes a difference.)

There's a whole zoo of algebraic systems (I think that's the term) -
monoids, semigroups, groupoids, groups, rings, fields, etc. They're all
essentially the same "thing", just with differing numbers of properties
guaranteed.
Personally, I only bother with fields and groups. A group is closed,
associative, and possesses a unique identity element and an inverse
element for every member. An Abelien group or commutative group is...
self-explanatory, actually?

More likely I copied the number out wrong...
