What’s a Martian meteorite, you ask? It’s a piece of rock that was
formed on the Red Planet, knocked into space by an asteroid or comet
impact, that somehow managed to crash-land on Earth. As one can imagine,
the odds against this happening are, well, astronomical! In fact, of
the over 60,000 meteorite specimens known to science, only 132 hail from Mars. A fragment from one of these was auctioned on ebay in 2003 for $450,000.

58,750
The US is giving Gaza $47,000,000 in "humanitarian aid". At $800 per missile, that will buy 58,750 missiles to fire at Israel.

164,597,832
164,597,832 = 6 x 7 x 9 x 524 x 831 .
Notice that both sides use each of the digits 1 - 9 exactly once.

422,481^4 ~ 3.18587 x 10^22
Euler conjectured that a 4th power could not be the sum of 3 4th powers. He was wrong. The smallest case is
422481^4 = 95800^4 + 217519^4 + 414560^4
422481^4 = 95800^4 + 217519^4 + 414560^4

60,000
The Seattle Fire Department says a man using a spray paint can and a
lighter to try and kill a spider started a West Seattle fire that caused
$60,000 worth of damage.
A fire spokesman says no injuries were reported.
The Red Cross is providing temporary shelter for the home's two residents.
It is unclear whether the spider survived.

0.207879576...
ii = 0.207879576... (i^î)
(Here
i
is the imaginary number
sqrt(-1). Isn't this a real beauty? How many people have actually
considered rasing i to the i power?
If
a
is algebraic and
b
is algebraic but irrational
then
ab
(a^b) is transcendental. Since
i
is algebraic but irrational, the theorem applies.
Note also:
ii
is equal to
e(- pi / 2 )
and several other values.
Consider
ii = e(i log i ) =
e( i times i pi / 2 ) .
Since log is multivalued, there are other possible values for
ii.
Here is how you can compute the value of ii = 0.207879576...
Here is how you can compute the value of ii = 0.207879576...
1. Since e^(ix) = Cos x + i Sin x, then let x = Pi/2.
2. Then e^(iPi/2) = i = Cos Pi/2 + i Sin Pi/2; since Cos Pi/2 = Cos 90 deg. = 0. But Sin 90 = 1 and i Sin 90 deg. = (i)*(1) = i.
3. Therefore e^(iPi/2) = i.
4. Take the ith power of both sides, the right side being i^i and the left side = [e^(iPi/2)]^i = e^(-Pi/2).
5. Therefore i^i = e^(-Pi/2) = .207879576...

7
The Number 7 is considered a lucky number in many societies. This may
have many different origins. There are religious origins as in the
seventh day is considered the Sabbath. Among the ancients, seven
represented the seventh son of a seventh son would be born with special
powers. The seventh daughter of a seventh daughter would be born with
the gift of healing.
Of course today, the number 7 represents luck in virtually every casino in the world. 7 is a winning roll in Craps when there is no number chosen. 777 also stands for a winning spin on many slot machines.

3792
I got an email:
_________________________________________________________________________
Amy --
$3,792.
That’s the magic number tonight. That’s how much we have to raise in the next 6 hours to hit our $550,000 Reporting Deadline goal before midnight.
Time is running out. Even $5 will get us that much closer to our mark. If you can, make a contribution tonight.
____________________________________________________________________________
I'm not sure what they are collecting for. Someone's campaign, I think.
