Another to speculate on then is how gravity would affect the evolution of life. The planets that we find that may have life on them will not necessarily be the same size as Earth.

So true. I'm sure that those statistics represent at most less than 20% of the total population (Actually, that is probably giving them too much credit). After all, a little more than 40% of the total population of the US actually vote for president, and even less for state governments and senators, so why would they even bother to answer this poll...

Well, I stand corrected then. What I'd like to know though is how many of those people who do believe are the older generation. In my school most anybody believes in evolution, or at least that evolution did take place. Again I don't think we have anything to worry about from the creationists. The bigger concern is that America is reported to have the lowest science and mathematics scores of any industrialized country, developing country, and even some third world countries. Take a look at this disturbing article written as recently as last year! link: http://abcnews.go.com/2020/Stossel/story?id=1500338 One has to wonder if there is a direct correlation...

Well, contrary to your claim, I don't think most Americans are on the creationists side. I'm pretty sure that most support evolution. Its just that the creationists are the ones who are the loudest and make it appear that way. I don't know if this will ever end. I'm sure it will though, since at this day and age this issue is now nothing more than an annoyance. And just because a creationist is president doesn't necessarily mean that schools will be forced to teach intelligent design as a science, as that would obviously cause some serious issues.

When you are depressed your brain chemistry changes, which is another example and a well known example of a physical cause. Drugs that treat depression usually aim to stimulate some neurotransmitters such as Dopamine. You can check for yourself here: link: http://www.nimh.nih.gov/publicat/depression.cfm#intro I mentioned this in another thread a long time ago (http://www.scienceforums.net/forum/showthread.php?t=25458), but I once attended a lecture by a guy with bi-polar who talked about depression and mania. He said that when one is depressed the brain reacts in a similar way when it is reacting to physical pain or physical trauma, so yes there is a direct correlation between mental and physical states. In the above posts however the controversy is revolving around the fact that people are being pressured into buying drugs they don't need because of the fact that it is easy to use mental disorders as an excuse or as a convenience to shy away from responsibility, to place blame, or mask the fact that it may be the fault of the system and not the patient in question. Also, some people just don't realize that people are just, well, different and that the "cookie cutter" just isn't an effective or efficient way to tackle a problem or address issues.

A race that I think is absolutely awesome are the Borg. Sometimes I wonder if we will one day end up like them, as we are certainly developing the technology right now that will allow us to interface with a computer and create cybernetic organisms. If there is anything I do question about them is the fact that they only send 1 ship to attempt to conquer the human race, and the other ones for that matter. Given that they are virtually invincible you'd think they would sent at least a dozen of them. But that is besides the point. Another thing about the Borg is their astonishing ability to regenerate, if you've seen that ability in Picard's first encounter.

I don't know, it seems like we are complaining about stuff that we can't really do anything about. For one, there are always going to be abysmally stupid people that will come by (check a couple of threads in the General Section for an example), and we can't do anything about that. Also, people make mistakes in their posts, and the best we can do about that is raise awareness among the members of this site to avoid doing that. Personally, I have a hard time finding what not to like about this site, other than the aesthetic appearance of this site. I like most of the people here, and I think the mods and admins do a good job maintaining this site.

I know that, but you need to know math in order to do physics. sorry if I didn't point that out or wasn't clear

I think this is just one of those threads made by people trying too hard to discredit the nay-sayers. I mean, seriously, in both threads (i.e. the Inconvenient Truth one and the Global Warming Explained one) the people who were pro-GW already won the debate by a landslide. They don't need post threads like this to prove their point, all this does is that it makes them look like crazy cult fanatics and jerks.

Well, mathematicians aren't notable for their high IQ's, just look at Richard Feyman, his test result was average. <edit> Richard Feyman was a physicist by the way.

Well, its not so much bending the rules of ecology as it is being able to control the factors that determine our survival, such as food supply. Humans have been able to do this for tens of thousands of years. The Agricultural Revolution was just another innovation that greatly increased our control over those factors. The problem is the fact that today's agricultural methods are very destructive, and inefficient as Swansont pointed out. Unlike more traditional methods, our methods destroy biodiversity, lower the nutritional value of the food we eat, and contribute to the depletion and pollution of our natural resources. I'm not sure how it works in other countries, but in the US most of our production of food is industrialized, right down to its growth. Our plants are grown in huge mono-cultures that spread out for hundreds of square miles. Because they are mono-cultures, they require an enormous amount of pesticides to ensure that they aren't eaten by bugs or microbes. Mono-cultures are also very fragile ecologically since they are only one kind of plant. With livestock they are injected with various hormones to increase their size and it is uncertain what kind of effect those chemicals have on human health in the long run. I remember attending a lecture on Agro-business not to long ago and they talked about the environmental impact and health impact. First of all, a lot of our food such as potato chips to drinks and even ketchup are made from corn! Of course, you would have figured this if you looked at the ingredients. Also, the variety and diversity of foods that was available before the second world war (before they industrialized food production) no longer exists. That means that some of the foods our grandparents may have eaten are no longer available for us to eat, and hence the availability of food itself has decreased because we killed off many other food sources.

lol! well, I'm just going to have to take that risk but you know what I mean.

You know guys the ignore button does work .

Its more than just politics, but I also think there is lots of money involved as well. One the one hand, gas company giants would want to present data that would contradict the IPCC claims so that it can continue to keep doing what it can. Also, the media and some liberal politicians are using this as a way to horde in lots of wealth; after all this would make any journalists careers and politicians can sway the public to get their vote. This is probably why there isn't much progress into actually reducing CO2 emissions or pursuing cheaper, more efficient energy options, of which I discussed in another thread. But yes, ecoli does have a point with how the data could be inconsistent on both sides. However, the one thing that is undeniable is that CO2 emissions have spiked up during the 200 years or so, especially during the 20th century. I read somewhere that the rate of CO2 emissions that occurred in the past century is the equivalent of burning all the land plants that have ever grown on Earth over the past 13000 years.

I was the first one to nominate .

`Deleted`. I had an example, but somebody beat me to it.

Certainly some new physics, though we won't know for sure what we will find once it goes online in November.

Yeah, this is pretty typical for a person with Autism. Often they have a very intense interest in some subject or some form of entertainment, and they can get quite good and knowledgable at it too, as in his case with Shrek. I need to know more details before I can determine what type of Autism he has because this is common with most any form.

Ok: Physical Properties vs Chemical Properties: 4 is still wrong. Solubility is a physical property because it determines how well it can mix with other substances. Physical vs Chemical Change: 1 is wrong. When a substance dissolves in a liquid, it is a physical change because it is not reacting with the liquid, just mixing in. 10 is wrong. Wood rotting is a chemical change. Substances vs Mixture: 6 is wrong. Alcohol is a substance (For example, the one we drink, Ethanol, is C2-H5-OH.)

Well, just about anything can be a substance. Air is a mixture of all different types of gases, and on Earth it is mostly Nitrogen and Oxygen. About physical and chemical properties: #2, 4, 8 and 12 are wrong.

Well, I guess if you put it that way, then I don't know if the chemistry of life on Earth is the only possible chemistry. But, to back my point up, DNA is the only known molecule that can self-replicate, and that is needed for life to actually exist. Also, even the life that live in extreme conditions are carbon based.

Well, cosmic rays hit the Earth with more energy than any particle accelerator that has been created to date, so no, I don't think we would destroy the universe with the RHIC

How many MOND theories are there? I've heard of one, in which I think goes like F=ma^2. I know acceleration is squared in one of them at least.

Does anyone here have any experience in programming video games of any sort? I've had a couple of ideas and reading those "Teach yourself Java" books, but experience is showing that this making a game is really, really complicated. I'm trying to make some sort of TBS (Turn Based Strategy).

I don't know. I like the Cenozoic era .
