The shrinkage of a body in response to cooling was experimentally derived by Dr. Costanza in the 90's.
We have to wear N95s in the medical profession if we are interacting with a patient with suspected or confirmed active tuberculosis. They are, indeed, miserable to wear. Try performing a complicated procedure that is hard enough normally with a mask crushing your face and the constant feeling of suffocation.
CS was a popular elective in my school (class of 2002). Full copying and pasting of programs, including the comments was routine for nearly the entire class. Even interested students such as myself (I had had some programming experience at a...computer camp in junior high), didn't really have the opportunity to learn anything from the teacher or write programs because of the attitude in the class. Of note, there were a lot of gifted & talented / AP / whatever students in the class that actually had rather high academic achievement in high school but the class had become a such a joke that even they copied and pasted the programs.
Of course, this is an isolated school. I'm sure things go differently in different schools, but I am sure code plagiarism (is that even the right term? I am not a programmer by trade) is fairly common when you get a high school teacher that is teaching out of the book and doesn't really care about the source codes as long as the programs compile and she can check the "pass" box in the grade book for the assignment.
We actually learned some true basic when I was in 4th-6th grade as a part of the gifted curriculum, and I received far more teaching at that time despite it not even being a full CS course...probably because the teacher actually cared.
Keep in mind that studies have shown that we only read the beginning and end of the words to save time, particularly when we are in a rush. Therefore astr - onom - y and astro - log - y can be interchangeable depending on how quickly you are reading. In the context of a survey that is predominantly concerned with science, your brain is most likely to spit out the definition for astronomy if it only receives astro **** y as input. The US has its fair share of idiots, but I'll bet that a significant amount of the 40 percent that "confused" the two actually know the difference.
P.S. I am too lazy to provide a citation because my psych 101 textbook has been in a landfill for 10 years and google did not immediately return the result I wanted.
I come to
/. for the comments, but with the new Beta, I can't even see anything! It just says:
''Shazbot! We ran into some trouble getting the comments. Try again... na-nu, na-nu!
It seems like the "developers" need to take some advice from people who actually know what they are doing. I'm happy to help explain what graceful degradation means if they like...

Boycott the site Feb 10-17th
If the beat is still here on 18th Feb do not return.
Do not fix that which is not broken."
Oh, BTW, FUCK BETA"
Slashdot has been around, well, a very long time. Longer than any of it's competators, but not as long as IIRC. Slashdot was a very much one of the first true social media web sites.
On Slashdot, you could create a handle or ID. Something personal, but not too personal, unless you wanted it to be. But it was not required either. We know each other by our handles, we have watched each other grow as people. We may have even taken pot shots at each other in threads. Unless of course you are anonymous, but often we can guess who that really is.
One of Slashdot's first motto's was "News for Nerds" that Matters. I have no idea when that was removed. I have not always scoured the boards here daily, life can get too busy for that. That excuses my ignorance in a way. I guess someone thought it politically incorrect, but most of us "Nerds" enjoyed it. We are proud of who we are, and what we know. Often we use that pride and knowledge to make someone else look bad. That is how we get our digs in, and we enjoy that part of us too. We don't punch people, we belittle them. It's who we are!
What made Slashdot unique were a few things. What you will note here is "who" has been responsible for the success of Slashdot. Hint, it has never been a just the company taking care of the servers and software.
— First, the user base submitted stories that "they" thought mattered. It was not a corporate feed. Sure, stories were submitted about companies. The latest break through from AMD and Intel, various stories regarding the graphic card wars, my compiler is better than your compiler, and yes your scripting language stinks! Microsoft IIS has brought us all a few laughs and lots of flame wars to boot. Still, we not only read about the products but get to my second point.
— User comments. This is the primary why we have been coming here for as long as we have, many of us for decades. We provide alternative opinions or back what was given in the article. This aspect not only makes the "News" interesting, but often leads to other news and information sharing. It's not always positive, but this is the nature of allowing commentary. It also brings out the third point.
— Moderation. Moderation has been done by the community for a very long time. It took lots of trial and error to get a working system. As with any public system it's imperfect, but it's been successful. People can choose to view poorly modded comments, but don't have to. As with posting anonymous versus with our own handle it's an option that allows us to personalize the way we see and read what's on the site. And as a reward for submitting something worth reading, you might get a mod point of your own to use as a reward for someone else.
Why we dislike Beta and what is being pushed, and why this will result in the end of an era if it becomes forced on the community.
1. Bulky graphics. We get that Dice and Slashdot need revenue. I have Karma good enough to disable advertisements, but have never kept this setting on. I realize that Slashdot/Dice make money with this. That said, the ads sit away from my news and out of the way. I can get there if I want it (but nobody has ever gotten a penny from me clicking an ad... nobody!), but it's not forced into my face or news feed.
2. Low text area. I like having enough on my screen to keep me busy without constant scrolling. Slashdot currently has the correct ratio of text to screen. This ratio has never been complained about, yet Beta reduces the usable text area by at least 1/2 and no option for changing the behavior. I hate reading Slashdot on mobile devices because I can't stand scrolling constantly.
4. Ordering/Sorting/Referencing. Each entry currently gets tagged with a unique thread ID. This allows linking to the exact post in a thread, not just the top of the thread. In Beta this is gone. It could be that the site decided to simply hide the post ID or it was removed. Either way, going to specific posts is something that is used very commonly by the community.
5. Eye candy. Most of us are not here for "eye candy" and many have allergic reactions to eye candy. Slashdot has a good mix currently. It's not as simple as the site starting with a r-e-d-i-t, which is good. That site has a reputation that keeps many of us away, and their format matches my attitude of them (s-i-m-p-l-e-t-o-n). At the same time, it's not like watching some other "news" sites with so much scrolling crap I can't read an article without getting a headache. The wasted space in beta for big bulky borders, sure smells like eye candy. Nothing buzzes or scrolls yet, but we can sense what's coming in a patch later.
The thing is, the community cares about Slashdot. We come here because we care. We submit stories because of that, we vote because of that, we moderate because of that, and we comment because of that. At the same time we realize that without the community Slashdot loses most of its value. We respect that we don't host the servers, backup the databases, or patch the servers. Slashdot/Dice provide the services needed for Slashdot.
It's a give give relationship, and we each get something in return. Slashdot gets tons of Search hits and lots of web traffic. We get a place to learn, teach, and occasionally vent.
Look, if you want to change default color scheme or make pre-made palettes for us to choose from, we would probably be okay with that. If you want to take away our ability to block ads by Karma, or move the ads to the left side of my browser window, I would be okay with those things too.
If you want to make drastic changes to how the site works, this is a different story all together. The reason so many are against Beta is that it breaks some of the fundamental parts of what makes Slashdot work.
User input until recently has not been acknowledged. The acknowledgment we have received is not from the people that are making the decision to push Beta live. We told people Beta was broken, what it lacked, and we were rather surprised to get a warning that Beta would be live despite what we told people. People are already making plans to leave, which means that Slashdot could fade away very soon.
Whether this was the goal for Dice or not remains to be seen. If it is, it's been nice knowing you but I won't be back. A partnership only works when there is mutual respect between the parties. A word of caution, us Nerds have good memories and lots of knowledge. The loss of Slashdot impacts all of Dice holdings, not just Slashdot. I boycott everything a company holds, not just the product group that did me wrong.
If that was not the goal of Dice, you should quickly begin communicating with the user base. What are the plans are to fix what Beta has broken? Why is Beta being pushed live with things broken? A "Sorry we have not been communicating!", and perhaps even a "Thank you" to the user base for helping make Slashdot a success for so many years."

Slashdot users are extremely unhappy with the new Slashdot Beta design. The comment section of every single post is devoted to dissatisfaction with the new design.
... ... The thing to keep in mind about community sites devoted to user generated content is that the users generate the content.
1) Absorption of the xray beam is not just based on a material's electron density. The contrast media we use today have a k-shell energy in the mid 30 kev which causes a sharp increase in the amount of absorption due to the photoelectric effect proportional to compton scatter. This means they have a higher absorption at these energies than their atomic number would indicate. Gallium's atomic number is lower than iodine's and its k edge is at 10 kev rather than in the 30s. I find it hard to believe that it provides better contrast resolution AT SIMILAR DOSES than iodine based contrast media. The actual paper (http://arxiv.org/ftp/arxiv/papers/1311/1311.6717.pdf) does not discuss the dose of gallium administered but based on the images I would assume they completely filled the coronary vasculature with gallium. This would not be compatible with life.
2) We have administered gallium 67 salts intravenously for medical imaging for decades, although it is out favor these days due to relative inferiority to newer imaging agents such as FDG-F18. Since the isotope is emitting photons out of the patient rather than us shooting photons into the patient and depending on gallium to absorb them, the doses are much lower for the type of imaging currently used than they would have to be for the proposed use as a contrast agent. As described above, completely replacing the blood with gallium to perform conventional or CT angiography would not be compatible with life.
