NASA lost contact with the orbiter during this morning around 9 am when the shuttle was scheduled to land. Search and rescue teams have been activated in Dallas and Fort Worth. 'Columbia was at an altitude of 200,700 feet over north-central Texas at a 9 a.m., traveling at 12,500 mph when mission control lost contact and tracking data. ' Update (fafalone): Wreckage from the shuttle continues to fall; there is no hope of crew survival from that altitude. A news conference is scheduled for 3PM. It may take days to ascertain what specifically went wrong, however there is some speculation that it may have been caused by a piece of fuel tank insulation that struck the left wing during liftoff, but NASA officials allowed the mission to resume, confident that there was no safety risk.

Trimellitic acid contains, C, H, and O and is 51.44%, 2.88%, and 45.68%, respectively, in these elements. It can be obtained by oxidation of coal with nitric acid. A 2.416g sample of this compound was dissolved in 40.0 g of acetone, producing a solution that boils at 56.64'C. K(subscript b) [boiling point depression constant] for acetone is 1.71'C/molal. Pure acetone has a boiling point of 56.20'C. From the percentage composition, determine the empirical formula. What is the empirical weight of the compound in grams per empirical unit. --- How do I do this. I have a feeling that most of the info given is irrelivant. I don't have my book with me

::puts on tin foil hat:: Well, they did crash here first.

Not sure what to make of the whole UFO scene. Maybe the government is testing something, or maybe their are actual UFOs of some sort "visiting" us. Of course, there isn't really any scientific evidence to back up UFOs, but there are eyewitness reports, military reports [from other countries], etc. Half of my class saw one when we were on our senior trip at Breckenridge. It was quite interesting, no one [the other half of the class who weren't with them when they saw it] believed them till the local news reported the sightings later that night. Its all very interesting to me, but I dunno.

Why don't we just discover cold fusion, downsize it, and implement it into future automobiles??? :confused:

have a group that you would do nothing but observe...no placebo, no lithium. be sure you randomly assign, don't sort out males, females, ages...etc

How do we isolate H2 efficiently? How do we store it? those are the issue not the formula

Meh, really no point. Just that we havn't really invented anything completely new.

Companies need to hire some people to figure out if more oil is being used to produce and bottle the hydrogen than it would be just to use the oil in combustion.

Haha no, it was a bio lab homework assignment. "Write a summary of ______" and they gave us a research paper. I didn't know if there was some official way, or if i was just supposed to do it how I felt it should be done.

Let me rephrase this because i think i'm being misunderstood. No idea is completely original; merely a compilation of things we have already seen or heard of. Describing to someone something they've never seen or heard of would be like describing color to a life-long blind man. For example, imagine describing a computer to a person who has spent their lives living in a remote jungle, and has never seen anything but his remote village. No matter how much time you spent describing it to them, they would still have to relate it to something they have seen. Now, imagine describing a computer to someone from the early 50s. They would have a much easier time understanding the concepts of a computer because they could assimilate various things they have seen [plastic, machinery, wires, etc] to compile themselves a mental image of a computer. ------------------ We cannot think of anything that can't be broken down into things we have observed.

Do YOU have any ideas? Perhaps we could help you elaborate on some...

Not sure exactly what you can do for an experiment. For this type of project research is usually conducted through data collection and compilation, and post mortem brain examination. Its quite unethical to bring in future suicide candidates to measure their brain chemical levels

... I'm not sure whether to laugh or run

The new one? It mentioned in the article that their was another that had been a fraud, but that this one had already undergone several tests Maybe they used a picture of the old fossil find?

edit: fafalone had already made that information public

This isn't really scientific, just something that crossed my mind. When was the last time you thought of something truly original? I've come to the conclusion that everything every idea either exists in nature, or is a synthesis hybrid of previous ideas. There are no original ideas. For example, think of something that you've never seen or heard about. I see a giant purple space meatball. Sounds original, but its not. I've seen a giant, I've seen purple, I've seen things floating in space, and I've seen meatballs. Perhaps we're not so clever after all, we're just good synthesizers.

I mean a summary of someone else's research paper

i'll try, but knowing my school ebonics is a recognized form of english

anyone know the "official" way to write a summary on a research paper? Due tomorrow morning Anyone know?

Obviously man made, still cool.

Sorry to bring this back up, but thought I'd share a cool crop circle i found. See that circle with the dots? Its an encoded cd, "The disc's message begins in the centre and is carried by a clearly defined data band or strip which spirals outwards. Each letter of the message is represented by eight 'bits', each bit being a uniform square of either standing or flattened crop. Each eight bit letter segment is separated from its neighbours by a narrower piece or ridge of standing crop and there is a very subtle crop mark generally discernible between the individual bits where a group of similar bits occurs. The process of decoding, then, is to read each group of eight bits from the photograph, enter the group in 0s and 1s into the calculator in binary mode, and switch the calculator mode to normal decimal, which will then display a number. Look up this number in the ASCII Character Set to obtain an English alphabet letter. Repeat this process along the spiral data strip to obtain the full ‘message'." The message is: “Beware the bearers of FALSE gifts & their BROKEN PROMISES. Much PAIN but still time. BELIEvE. There is GOOD out there. We OPpose DECEPTION. Conduit CLOSING. Acknowledge."

Well, if it makes you feel any better, it froze my computer too. Every time the server has an SQL error, it sends the error report to me in ascii format to my email. So basically when I opened the email, I got a display of the full file in ascii format, which my beast of a machine (800mhz, 128mb ram) didn't like Needless to say, I ended up rebooting. BOO.

"I'd love to view these but I'm not installing two programs I don't want just to do so. Is there any chance you could convert them to a more familiar format?" I don't think he was really complaining, just asking a favor. Given the politeness of his statement, I don't understand why it couldn't have been a friendly exchange.
