A National Security Letter (NSL) is issued by the FBI, and it allows the FBI to demand information about suspects without obtaining a search warrant, in addition, the receipient is prohibited from telling to anyone that they received it. Here is one online:
http://www.aclu.org/nsl/legal/NSL_formletter_080404.pdf

Of cource, anyone receiving one is free to treat it as toilet paper since in September 2007, a federal court ruled that the gag provision of NSLs was unconstitutional.

And now we present: Kazakhstan's pyramid.



That would be the one in Astana, it's brand new capital and pre-planned city for 1 million inhabitants?

Pre-planned cities FTW, you get cool road patterns and streets and buildings. Possibly you can rig it so that they form an amusing shape when viewed from a certain angle. Although a friend of mine does bit-work for council planning (one thing he did was planning for a massive new development, although it was just a town for ca.30,000) apparently it's an absolute BITCH to do.

Here is an interesting fact:

Why, are veins Blue?

Some, might say because oxygen deprived blood is blue. Those are the same some however who have never wondered:

When was the last time you saw someone bleed blue?

If blood without oxygen was blue, there should have been a great deal of public knowledge of images of persons, bleeding blue, cutting a vein and making a blue mess, blue stained clothes, blue dipped swords and so on. I mean, haven't you ever as kids try to cut yourself when you were feeling really down, but also thought, since you are up to it to refill two inks of your printer rather than one, but couldn't find that blue blood no matter how hard you tried?

The answer then is, that blood is actually always red and surgeons can atest that they, in fact, don't see any blue veins around. The answer apparently is:

Skin does not absorb much light at any wavelength, making it look white (depending on how much melanin is present)
Blood pretty much absorbs all wavelenghts, which makes it look "dark", but it absorbs less in the red part of the spectrum, ending up reflecting red (and so it looks dark red)

Red light however doesn't penetrate the skin as good as blue light. This because blue light has a higher frequency and so energy than red light.

If a vessel is near the surface of the skin, the much higher ratio of red vs blue light absorbed because of the blood's natural colouring makes it look red.
If a vessel however is deeper then only higher frequency "lights" remain to be reflected (the bluish ones).

It's not blue, per se. Not literally, of course- it's just quite dark red. And, I think exposure to oxygen might excite oxidation which could make blood lighter after a brief period? I don't know.

I've seen "venous" ( de-oxigenated ) blood, and it is darker- but is not "blue".

And the reason you never see the de-oxygenated blood, is the second the vein is cut, all the blood in the general region becomes oxygenated.

Bottom Cop

in July 2006, to avoid felony indictments and possible jail time, former commissioner of NYC Department of Corrections Bernard Kerik pled guilty in New York to accepting $165,000 in free construction work from a company publically linked to the mob...

this was not the first time he had run into trouble... 

in 2002 he joined the board of Taser International, which sells stun guns to such customers as the Department of Homeland Security...  Kerik was criticized for tradinh on his 9/11 celebrity when he was granted and exercersized $6.2 million in stock options...

in May 2003 he was sent to Iraq to rebuild the Iraqi police force, but he quit  and returned home 3 1/2 months later, amid charges of corruption and mismanagement... 

and in December 2004, he was forced to withdraw from consideration for Homeland Security Director after details surfaced of an illegal nanny, his use of  Ground Zero rest apartment, and the aforementioned mob allegations...

This, blue crap, is the Cosmic, Microwave Background Radiation.

It is rather uniform and it comes out of all points of the universe.

Now what it is. You know that light has a certain speed right? (c)
This means that it takes time to reach something somewhere. It takes 1.2 seconds for light to come from the moon, and 8.5 minutes to come from the sun. It takes 3 minutes to reach Mars, at its closest, and I say at its closest because when the planets are on the opposite sites of the sun each, that would be 42 minutes.

The effect of that is that when you look at something far away (or to be more accurate, you are receiving light that has reflected off something far away) you look into the past. The image of the moon we have for example is from 1.2 seconds in the past.

Well, it so happens then, that the microwave background radiation is the resulting of looking so far away into the past, that is nothing more than radiation from the afterglow of the Big Bang itself. In other words, yes it might be a "theory" (as is the atomic one I always point out) but we kind of "see it".

That of cource posses certain problems with members of a certain cult, that still hasn't synchronised itself with western science.

By sheer coincidence one of said members, was George Deutsch, NASA's press officer, Appointed appointed to the position by George W. Bush, apparently he caused quite a stir there and became loveable after he ordered a NASA website designer to add the word "theory" after every occurrence of the phrase Big Bang.
Quote
In his memo to the website designer, Mr. Deutsch wrote that the Big Bang is "not proven fact; it is opinion... It is not NASA's place, nor should it be to make a declaration such as this about the existence of the universe that discounts intelligent design by a creator... This is more than a science issue, it is a religious issue."

Thats what he said to the guys who kind of, in the next room, not only kind of see the thing, but design the next mission to increase the resolution.

But thats not the funny thing, the funny thing is that the same guy was also found to have lied about having a B.A. degree in journalism from Texas A&M University. As in, he plain lied. The University was asked and they said "who?" which ended up being the thing he had to resign for.

Complete trainwreck.

Flying High

Dubya Bush joined the Texas Air National Guard, where he was trained as an F-102 pilot...   after winning his wings, he transferred to the Guard's "Champagne Unit", made up of the sons of priveleged Texas families who wanted to avoid serving in Vietnam...

during his six-year period of obligation, Bush was absent for months at a time, without leave or explanation...

the Air Force suspended his flight status 18 months before his enlistment elapsed...  he received an honorable discharge six months early, without further official comment...
