Slashdot Mirror

Maybe I missed seeing this in the other comments, but massive arrays here on earth are approaching and surpassing Hubble's abilities. So it is not true that we will be plunged into an eternal darkness until the new scope goes up.

While Hubble does have perfect seeing in space, it is really starting to suffer by being just not very big. Frontline research telescopes on Earth like Keck are far larger (thus more light gathering power), and, with adaptive optics, rival Hubble's resolution. Also, earthbound radio astronomers are doing high-resolution imagery with aperture synthesis that is of the same order of resolution as Hubble.

Bear in mind too that those were 1.5 billion 1980s dollars. Inflation will have changed that number by now.

you're a liar and a snotty elitist liar at that. If you "always thought it was a kuiper belt object" then you either never HEARD of Pluto before 1992 (when the Kuiper Belt was discovered), you somehow discovered the Kuiper belt before NASA did (in which case you're an idiot), or you just want to sound smart (in which case you're actually just an idiot). Or maybe you're trying to look "cool" - and even for slashdot, you look like a nerdy idiot (now that's hard to do).

my high school biology text books never talk about the 100th monkey thingy

there are people that use the guise of religion as a reason for violence. But there are those also that use atheism for exact same purpose and reason.

Communists believed that they knew the truth, absolutely. They believed that they knew through Marxism what would bring about the greatest human welfare and happiness. And they believed that power, the dictatorship of the proletariat, must be used to tear down the old feudal or capitalist order and rebuild society and culture to realize this utopia. Nothing must stand in the way of its achievement. Government--the Communist Party--was thus above any law. All institutions, cultural norms, traditions, and sentiments were expendable. And the people were as though lumber and bricks, to be used in building the new world. Constructing this utopia was seen as though a war on poverty, exploitation, imperialism, and inequality. And for the greater good, as in a real war, people are killed. And thus this war for the communist utopia had its necessary enemy casualties, the clergy, bourgeoisie, capitalists, wreckers, counterrevolutionaries, rightists, tyrants, rich, landlords, and noncombatants that unfortunately got caught in the battle

People have killed more in the name of religion

Bullshit. Communist (atheistic) states were responsible for about 100,000,000 murders in the 20th century. Hitler's atheistic Nazis killed another 11,000,000. It's amazing to me that people still push this stupid notion.

HOW MANY DID COMMUNIST REGIMES MURDER?

Am I missing something here? Can someone please explain to me how to use a laser pointer to look at stars?

Two ways.

Point it at the star. The one that reflects after several decades is the one you're looking at.

Spend several million on one of these

Not too bad - see our usage page.

I work for the Joint Astronomy Centre and did some of the work in putting those images together. If I remember correctly, I made the JPEGs from the PNGs with ImageMagick's "convert" tool. ImageMagick does seem to support JP2, but I don't know how much it is in general use (I haven't tried it myself) so I usually go for normal JPEGs in order to make sure as many people as possible can view the images.

Yes, I work there. No, I don't use oxygen. Below about 15000 feet the TUC (Time of Useful Consciousness) is "indefinite" which means some people can go hang out for 12-14 hours with nothing bad happening. There are some observatories up there that are talking about creating a single pressurized "break room" for staff - not where I work, though. :)

Oh, and the Rockwell HAWAII-2RG 2048x2048 sensors used to build UKIRT's WFCAM (it has 4 of them in a square array) were co-developed by U. of Hawaii, Rockwell Scientific and UMC, and first deployed in November of 2003 in the "ULB" camera on 88. For some time, 88 with ULB was the most powerful infrared setup for astrophotography; since UKIRT is the largest dedicated infrared scope in the world, it will now (with its own 16-megapixel camera) really take some great pictures. :) I was over at UKIRT for their 25th anniversary open house, and it's one BIG instrument.

...of course, Gemini South (8.1-meter) has ordered some HAWAII-2RG chips from Rockwell, I think... and the European folks are mumbling about doing a 4x4 array of them (64 megapixels) for their forthcoming VISTA telescope in Chile, which will be the bigger better successor to UKIRT.

Check out the man hidden in the bottom left of this image, look at the outline here!

There is government funding. See Pan-STARRS and LSST. These surveys will find millions of objects, and thousands of PHOs.

A lot of observing and imaging of comets and their dust comas, and analysis of the resulting images, is being carried out by Jana Pittichova, a postdoctoral fellow (and triathlete!) on Karen's research team, primarily using the University's 88-inch telescope atop Mauna Kea.

Being one of the operators on that telescope, I've worked with Jana on several nights - probably one-third to one-half of the Meech team's total observing this semester.

Although I understand how the observations are carried out from a purely operational and practical standpoint, I haven't seen what the actual analysis looks like... and even if I did, the odds are good that I'd need a lot of explaining, since I'm not a Ph.D. myself!

Forget about what the Senate heard; that's just political nonsense. But this subject does raise an interesting question: Exactly what effect has the increasing availability of porn had on people?
I'm not condemning it, or praising it. I'm asking a basic question. What is the effect (good or bad) of this being the first generation of children and young adults for whom porn has been ubiquitious and easily available in the comfort of their own home? In no other generation in history has this been the case, to my knowledge. Yet kids today can access porn any time they want. They are growing up with ready access to any image you can imagine.

So what is the effect? I truly have no idea. I'm not condemning porn. I'm just wondering. Will this have a good effect, making kids more at ease around sex, not viewing it as this mysterious, dirty subject? Will it have a bad effect, conditioning them into thinking of sex in an unrealistic way? Guess we'll find out over the next decade as they grow up and enter society.


Read this link. To find out what it did to Japan.

"It is certainly clear from our data and analysis that a massive increase in available pornography in Japan has been correlated with a dramatic decrease in sexual crimes and most so among youngsters as perpetrators or victims."

Because 30M is a gross lie.

See that, it's called a reference. You should use them. Of course, then you would be wrong most of the time, and I'm sure you don't want to do that.

Hormel might do well to focus more on international sales. Here is Japanese fusion dish known as ,SPAM MUSUBI which is most delicious (jpeg).

Pork is so revered in China, where the pig symbolises good luck, fertility and virility, that the meat and pork are the same word! Hormel would do well to add a large, smiling, tumescent, gold bling wearing, surrounded by bitch pigs, pig to their package label for sales in China. It might help to put him on a Harley as sort of an inside joke for the more cosmopolitan Chinese.

While they do have turkey SPAM I've yet to see an 'all beef' version. With one world government on it's way, and if you believe Jack Van Impe an Islamic government at that, Hormel would do well to push an all beef product,

Down the road, when they've got the market cornered, it will be time to branch out into flavored varieties. For example "All Beef Spam with SQUIRREL BRAINS" should sell well in SE Tennessee.

Japan underwent a massive swing from one of the most conservative nations with respect to pornography to one of the most liberal, and extremely accepting of fetishes. There was a corresponding *decrease* in sex crimes.

Interferometry of this kind is (with current technology, but even in principle) only conceivable with radio astronomy, not with optical astronomy.

Perhaps I'm reading this wrong-- or misinterpreting what you mean by "this kind". The WM Keck telescopes in Hawaii-- visible light scopes-- already use interferometry.

The principle is exactly as you describe, with timestamped data being combined on a separate processor.

Interestingly, other arrays (planned or already existing) that are designed to search for other types of signals-- such as LIGO-- use the same principles. In this case the quarry is gravity waves (predicted by theory but not yet detected), but it works by interfering the results of two linear beam detectors. When a gravity wave moves through (in theory), it disturbs the beam in one arm of the L-shaped detector more than the other. Since the wavelength is calibrated to normally exactly cancel, knocking it just slightly off-kilter will result in the sudden detection of a signal. Multiple installations are scattered across the world, partly so that each can verify the results of the others, partly so that, in the event that a wave is detected, the timestamps on the interferometers can be used to triangulate the source-- much the same way that seismologists triangulate the epicenter of an earthquake.

Sorry about these amazingly long run-on sentences!

I don't see the United States on that list, if it should be why does it get so much of the attention rather than the other countries committing more atrocities?

Ideally the answer would be "Wherever I can do the best work", but we're all human.

(The site surveys are going on right now, and I work at one of the sites being surveyed.)

If you can put one of something in orbit, you can probably put a whole lot more of something on the ground for a whole lot less money. ;)

Sorry.

How about the facts that:

* under Chairman Mao in China, 35m intellectuals died as a result of the "Great Leap Forward".

* under Hitler (leader of the National Socialists (Nazi) Party), 6m Jews died

* under Stalin (leader of the United Soviet Socialist Republics (USSR)), over 20m people died

These are all unrefuted facts. Notice also, that by strict economic definition, these were all socialist economies. They were all state-run, command economies -- that is the very definition of socialism.

This study shows that governments -- particularly Marxist/communist/socialist governments have killed about 120,000,000 people during the 20th century. 120 million.

Why is it that socialist nations tend to be totalitarian? Perhaps it is because in order to get the economy to be productive (rather than having people loaf around on their welfare checks), the state must force those people to work?

And why is it that socialist nations which do not use such force, generally -- such as Sweden -- have low rates of economic and technological growth compared to capitalist nations? (please see the CIA World Factbook).

I am quite aware of what socialism is. I have been studying economics for a few years now.

I have a better idea. Rather than me telling you what socialism is, why don't you go read The Road to Serfdom , then come back and tell me why socialism is a good thing?

Actually, what you're talking about is interferometry, which is next to useless for detecting moving objects. The problem with interferometry is that it gives you a very narrow field-of-view, which is exactly the opposite of what you want for detecting moving objects.

What the parent poster is talking about is having multiple telescopes looking at the sky independently of one another. Smaller telescopes are better because they're cheaper and they generally have a wider field-of-view. Some projects that are doing things like this are eSTAR and Pan-STARRS.
