No, not the article itself, but the habits of ipod people(hah a name for a bad 50's sci fi flick), and other people who use portable music devices. Bottomline, listening to a music player in a noisy environment is bad for your hearing.
Example, start out at home or in a very quiet environment, keep the volume at what you might consider an appropriate level of hearing. Now go to some place where there is more noise activity, that same volume will not be adequate. What is going on is that people are raising the volume in an attempt to drown out environmental noise. If the outside volume is at 70 decibles, people might raise the player volume to 80 or 90 decibles to listen to music. That can cause permanent hearing loss if exposed to long enough.
There are three options, a headphone/earbud set that is designed specifically to dampen outside noise. The best reduction headphones might get is 25 decibles. The other one would be the noise canceling type of headphones, but they only work for constant noise(like an airplane or a car, I had a pair that worked so good I just left them on for the flight because it reduced the engine noise). The most impractical would be to wear a pair of saftey earplugs and using headphones.
Again when none of these work well, it means the environmental noise is loud to the point where you shouldn't be trying to listen on a portable music player.
Wi Fi is of the same wave frequency as microwave, so the fear that it might have the same cause and effect as a cellphone up to someone's ear is not at all far fetched.
What disappoints me about the documentary is that they aren't trying to compare and contrast the effects a cellular phone has up close to a person's head and match that up with being inside a wi fi area.
Most states do not recognize private rating systems under a legal jurisdiction. What can the state deem viewing appropriate to people under the age of 18 is pretty much only absolute when visual depictions of sex are involved.
Stores wanting to look like responsible businesses will have their own policy of id'ing anyone if its rated mature. Much in the same vein as the comic book authority or the mpaa rating system, the private ownership of ratings means that at the very least, legal responsiblity for a minor seeing an r rated movie, or playing an m rated video game is no where except on the parent themselves.
There is however precident that Thompson wants, he did lobby for Louisiana to make the M-rating half equivalent to the Nc-17. Again the problem can be broken down to the very simple fact that no private rating system is transparent enough to the point where every reasoning for the system is agreed upon. I don't see this court case actually going anywhere but at a settlement. If Jack thinks this is some kind of indiciation that he is in the right, he would have to be very insane to think so.
If there was a government rating system, then at least we can see the documents for ourselves and see how they rate media. It also gives an opportunity for the consumers to adjust the system by means of voting power. But as it stands a private rating system doesn't allow us that luxury, so for example movies that would be passable for Pg-13 standards will be rated R or NC-17, while ones that could be NC-17 would be rated R.
My thoughts from what scant information there is in the news right now. The university police(not the real cops) got the call that gun shots were heard in the dorm. They were doing an investigation at the time, it would take two hours for them to get close to discovering what was going on. My thoughts are that they didn't even realize anyone was injured or killed because they weren't going into people's rooms unannounced.
Again I and I'm sure most people do not know the full details, if people were killed and the police knew about it at the time of their investigation, then the only question for that scenario is why did the president of the university not immediately announce a mandatory lock down?
The scientist who looked at the polar ice cap melting said it was from a global climate change on mars, while discussed in this link http://www.realclimate.org/index.php?p=192 the ice caps are melting due to regional climate change. That conclusion was based on numerous data measurements across the planet of mars. The inferrence of solar radiation and global climate change on mars is baseless.
I think the parents who complained are tired of having their kids subjected to advertisements. It's clear that these ads are targetting kids to nag their parents into getting these cars. Read up on "the nag factor" to understand how advertisers are trying to indirectly sell adult items through children.
Yes but the cost of lawyer and court fees are numerous to a student. It is possible that the 40k and selling his car was cheaper than being in court and risk loosing.
Apparently the Penrose tile has a trademark which prevented a generic company from printing the pattern on toilet tissue. I suppose that since the photograph of arabic medieval art looks spot on to the penrose trademark, is this an example of "prior art" and thus Penrose tile can't make a valid claim of discovery?
There are algorithms within reasonable time constraints to solve coloring problems on a small scale. Sudoku is fixed on a 9x9 grid where the puzzles have to have a unique solution. Nothing needs to be made as to guess work. This is very different from a game like Mine Sweeper where no known efficient algorithm exists that can solve it every time.
In general a nxn grid is np-complete, sudoku isn't a generalization, its fixed on 9x9 grid, where within a 3x3 grid every digit shows up once.
Sudoku and Traveling Salesman problem are related, but they are not exactly the same.
Sudoku is analogous to finding a 9 coloring on a graph with 81 vertices from a partial 9 coloring. Coloring on vertices are determined by their relationship with other vertices, if they are independent, then they can have the same color.
Traveling Salesman is similar to finding the most efficient hamiltonian path on a weighted graph. The ability to travel across all vertices in the shortest distance possible.
They both can relate to topics in graph theory, but they are different problems because Sudoku does not have to worry about the weight of an edge(i.e. the distance in miles from Portland to Denver). From current algorithms, a traveling salesman problem has a complexity of 2 raised to the nth power. Sudoku has complexity of n squared.
Yes I can see this super computer being used to evaluate vast networks of roads in America to determine the most efficient routes. Because the computational time is so long a super computer is neccessary for this kind of work.
There are a lot of misconceptions running around on this blog, so I won't respond to them on a post by post basis. Rather I'll just list some and respond to them.
1.) An embryo is a fertilized egg.
Wrong, an embryo is a cell. Fertilization is a process an embryo can be subject to.
2.) Embryonic stem cells are destroying fertilized eggs.
The process of creating embryonic stem cells is taking an unfertilized embryo, replacing the native dna material with the dna of the thing that is to be cloned. This embryo is not fertilized with a sperm, nor is it fertilized in the biological sense. This embryo is not capable of cell division naturally. After the dna material is replaced, a small current is applied to the embryo to force it to undergo cell division. It's not natural fertilization, nor was it fertilization in the first place. Fertilization requires both host dna and the mate's dna.
3.) Creation of stem cells destroys a potential life.
The odds that the process to make stem cells can make a fully developed life form is very very rare, more rare than fertilization. If they just let the embryo continue cell division, the chances of it making it to the fetus stage and beyond is over one and a hundred. Their were hundreds of failed attempts to make dolly the sheep, which in the end died because of health problems. So again there wasn't complete success in making a healthy life form.
4.) extraction of Amneonic fluid is dangerous.
Doctors do these kinds of testings all the time. It is a test done in prenatal care to detect any potential health problems early on. This would not be a practice at all if the risks to the unborn was greater than the benefits. If someone asked me if I would subject my daughter to amneonic fluid extraction, I would say yes, it would a.) ensure the safety of my grandchild, and b.) contribute to the sciences, its a win win situation where I and my daughter get cake and eat it too.

If the drug kills the cancer cells inside the body, does the body naturally remove the cells? Or do they need to be removed?
Yes but the point is that embryonic stem cells are not created from a sperm fertilized egg.
