Comment Re:Scientists Vote Sceptic (Score 1) 695

This is not what belief means. If you believe something, it just means that you're convinced enough that it is true to act as if it were true. It does not mean that you cannot or will not change your mind. As a physicist, I believe that electrons exist, but this does not mean I could not be convinced otherwise. On the other hand, I do not believe that neutrinos travel faster than the speed of light, but this does not mean I could not be convinced to change my mind. I would say that I am skeptical about the existence of superluminal neutrinos, but I'm certainly not any sort of "electron skeptic".

This is why, when someone says that he a "climate change skeptic", I'm never sure whether he is just very careful about attaching the "belief" label to things (as Manip is), or if he really does have serious doubts that climate change is happening and caused by humans. This is why I don't normally tell people I'm a climate skeptic, even though I do have some doubts about certain aspects of the issue, and I am well-open to the idea that my beliefs are wrong.

The real trouble is that being a "believer" and a "skeptic" are not mutually exclusive.

Comment A good neighbor (Score 1) 70

I lived next to him while I was attending U of I as an undergrad. He was a great neighbor. The house I was in had five bedrooms, all occupied by male college students. He told us we could have parties and be loud, so long as we warned him, and gave him $20 to get a burger and see a movie.

Comment Physics Van! (Score 1) 225

The University of Illinois Department of Physics has a good site for their outreach program, the Physics Van: http://van.physics.illinois.edu/ It's good if kids want to ask questions of professors and students in the department, or read previous answers to questions. It's also good if you or the students want to learn about demonstrations, some of which can be done at home.

Currently, I pay the bills as a graduate student by going to elementary schools to do physics demonstrations on behalf of my department (not at U of I). I don't know where you teach, but there is probably an outreach group nearby (at a University, National Lab, or even a corporation that employs research scientists) that can come to your school. I realize you weren't asking about live demonstrations, and I certainly think you're doing the right thing looking for good, engaging online activities, but I still think this bears mentioning.

Another thought is that because clear and accurate representation of results is so important in science, you might consider doing an activity that involves a computer visualization of some kind of measurement taken by the students. You could even have them publish it on the web. It wouldn't need to be anything super-fancy, just something to encourage creativity and careful thinking about what the results mean and what's important about them.

Good Luck!

If this is trolling, it is very good trolling. If it is not, it represents the majority opinion of people who contribute to the car culture in this country and make it unsafe or impractical to use alternative transportation. Either way, you should grow up.

The fact that they're wrong isn't necessarily important, because they're still *useful*. If you are in a geeky field that involves solving problems, and most of those problems can be solved using techniques governed by very good approximations, such as Ohm's Law or Maxwell's Equations, that seems to me like a good tattoo to get. Similarly, if you do work with nonlinear devices where Ohm's Law breaks down, why not get a tattoo of the contradiction of Ohm's Law (V != IR)?

Tetris Clones Pulled From Android Market 396

sbrubblesman writes "The Tetris Company, LLC has notified Google to remove all Tetris clones from Android Market. I am one of the developers of FallingBlocks, a game with the same gameplay concepts as Tetris. I have received an email warning that my game was suspended from Android Market due to a violation of the Developer Content Policy. When I received the email, I already imagined that it had something to do with it being a Tetris clone, but besides having the same gameplay as Tetris, which I believe cannot be copyrighted, the game uses its own name, graphics and sounds. There's no reference to 'Tetris' in our game. I have emailed Google asking what is the reason for the application removal. Google promptly answered that The Tetris Company, LLC notified them under the DMCA (PDF) to remove various Tetris clones from Android Market. My app was removed together with 35 other Tetris clones. I checked online at various sources, and all of them say that there's no copyright on gameplay. There could be some sort of patent. But even if they had one, it would last 20 years, so it would have been over in 2005. It's a shame that The Tetris Company, LLC uses its power to stop developers from creating good and free games for Android users. Without resources for a legal fight, our application and many others will cease to exist, even knowing that they are legit. Users will be forced to buy the paid, official version, which is worse than many of the ones available for free on the market. Users from other countries, such as Brazil in my case, won't even be able to play the official Tetris, since Google Checkout doesn't exist in Brazil; you can't buy paid applications from Android Market in these countries."

Scientists Say a Dirty Child Is a Healthy Child 331

Researchers from the School of Medicine at the University of California have shown that the more germs a child is exposed to, the better their immune system in later life. Their study found that keeping a child's skin too clean impaired the skin's ability to heal itself. From the article: "'These germs are actually good for us,' said Professor Richard Gallo, who led the research. Common bacterial species, known as staphylococci, which can cause inflammation when under the skin, are 'good bacteria' when on the surface, where they can reduce inflammation."

You also have to keep in mind that for something about which we know so little, learning more about it will probably lead to applications we haven't even thought of yet. When X-rays were discovered, do you think Roentgen immediately thought of using it for detecting weapons in bags or measuring atomic spacing in crystal latices? Probably not. It could very well be useless, but I expect we will find something useful to do with them if and when we detect them (assuming they exist).
