Japan's -what- 6TH Prime Minister in HALF A DECADE

he's in trouble

Naoto Kan, the current prime minister of Japan,  is being blamed for the delay of emergency procedures at the Fukushima nuclear power plants and a pot of other complicated things.

He's the 5th PM of Japan in 4 years (if I wasn't losing track of PMs)
Weird, right? And normally, PMs stay in office for 4 years.

When Koizumi quit the seat of PM after a long happy 1980 days, Abe took on. (not read "Abe" as in Lincoln's nickname, but sorta like "a- bay")

Meteorites (part 2 -rock or metal - or both)

part 1 is here- http://odysseypod.blogspot.com/2011/05/meteorites-part-1-basic-info.html
There are mainly 3 types of meteorites-
iron, stony, and stony-iron meteorites.

Iron meteorites are made of- you guessed it- iron.

They're the closest to our mental image of "meteorites", so most of the meteorites that landed a long time ago and have been just recently discovered is this.
Of course, there maybe a lot of stony meteorites rolling around everywhere,

Meteorites (part 1 -Basic info)

part 2 is here http://odysseypod.blogspot.com/2011/05/meteorites-part-2-rock-or-metal-or-both.html
I'm gonna go to a mineral fair next Monday, and I want to buy a meteorite there, so I thought I should learn a bit about the rocks from space.

Meteorites come from space, so they have to enter the Earth's atmosphere. They enter at great speeds into it, so the friction with the air is huge and it heats up a lot. (that's why spacecrafts have heat shields- to protect it from the heat of re-entry)
this is a meteorite I have. You can see the fusion crust
it's cool knowing this tiny piece of rock came from space :)

But of course, rocks don't have heat shields, so its surface melts and forms the fusion crust- a thin(about a millimeter) black layer covering the meteorite.

The surface of the crust is a little coarse and has shallow dents, because the pointy edges melt down with the heat.

So, I thought, "a 1 millimeter layer? duh, that's nothing!" and so...
I carved A LITTLE BIT of it and tried to see how it looked like.
Sure enough, it didn't go exactly as I wanted.

But still, I think you can see a glimmer of silvery stuff peeking out from the carved area.

Dimensions (part 2. dots, lines, squares and cubes)

(some ideas here are mine, and I'm really not an expert about these dimensions, so please, please take them with a grain of salt)
Part 1 ended with a confusing hypercube
So this time let's just look at what we know best- dots, lines, squares and cubes.
Hypercubes won't come out today(except for the very end, a tiny role.)

dimentions form]
This form counts the number of dots, lines, squares and cubes in... a dot, line, square and a cube.
To make explaining easier, I'll call each of the components x-D components (a dot will be 0-D, lines are 1-D, squares are 2-D and so on)
For example, a square is made from four 0-D components (dots), four 1-D components (lines)  and one 2-D component (square). Get the idea?

As you can see, the number of 0-D components always gets multiplied by 2 every time there's a new dimension.
This is because, adding a new dimension means you slide the shape from one dimension back to another direction. (e.g. to make a square, you slide a line in the direction of the Y-axis)

So when you think about it, it's natural that the number of dots gets multiplied every time there's a new dimension.
With that info, let's look at the number of dots in  hypercube(you know, this one)
yep, it IS 8 x 2=16 dots!!

So next time, let's look at this hypercube with the number of dots, lines, ...(i hate having to have to keep repeating this)
... well, components, in short.

I think I've got a pretty good idea.
