Why do we get light from collapsing underwater bubbles?
pwagen replied to dimreepr's topic in Quantum Theory
Not quite. So while it seems the light is due to the temperature, the way I'm reading it, it's still unclear what causes that. I vote aliens. Maybe the same ones that made the cross on the Sun. -
I'm still talking about the scientific consensus. You claimed that "scientists say..." and then went on to give an inaccurate description of what scientists actually say. Scientists don't say "first there was nothing". The origin of the components are unknown, and might very well stay that way. Therefore it's incorrect to say there was nothing to begin with, the components might as well have been there for an eternity, we simply don't know. But not knowing is not an excuse to put misconstructed ideas into scientists' mouths. If you want to be picky, there also was no explosion. There was, and still is, an expansion. Not quite, but it's a common misconception. The BB theory doesn't deal with the actual origin, it only describes the process of expansion which is still observable today.

I have no idea what any of that is supposed to mean. But I will say this: If anyone feel personally insulted when their theories or ideas are debunked/falsified/corrected, that's their problem. They are not their ideas and their ideas are not them. Telling someone they're wrong is not disrespecting that person. If, however, someone goes on targeting a person instead of what that person is saying, that would be an ad hominem, which is a logical fallacy. For example, telling someone to "use one brain cell" doesn't add a whole lot to a discussion, now does it?
-
It's obvious you're wrong on the current scientific consensus. In other words, what "most scientists say". While I appreciate my unimaginable intellect might shine through despite me trying to be subtle about it, I don't claim to know the answer to "the ultimate question". Unless, of course, you're talking about the question from the Hitchhiker's Guide to the Galaxy, then it's 42. I do, however, know that the whole "first there was nothing then this nothing exploded" is complete bunkum.
-
Citation for the "first there was nothing then it exploded", please.

That's not how I read the question. As far as I understood it, the question is only whether gas has been solved, or it's pure water. Of course, if there are other options than gas, tasting probably wouldn't be definite, unless you're very familiar with the taste of a certain gas.
-
3 ways to decide whether there's a gas in a solution, OP's question! Mind you, I'm no chemist.
-
So bubbles, PH and... tasting it?
-
Fixed that for you. You're welcome.

Can wisdom teeth affect your speech at all?
pwagen replied to Fanghur's topic in Anatomy, Physiology and Neuroscience
Sure, I can imagine it does. Anything in your mouth probably affect your speech in one way or another, your teeth should be no different. If they're growing the wrong way, it's even more likely removing them would make a change for the better. As another example, I have a friend who's got a tongue piercing. And when she removes it, she starts lisping. In her case, it's the other way around - a foreign object in her mouth (and please don't go down the gutter with that one) allows her to speak better. -

External influences on the development of science
pwagen replied to Alfred001's topic in Other Sciences
A never ending source of material would be the ongoing attempts to indoctrinate children in the US with idiocy creationism because of religious dogma. -
Reasons not to worry (Climate change debate)
pwagen replied to Tim the plumber's topic in Climate Science
Yes, because why would you want anyone else's opinion now that yours has been "confirmed"? -
You might want to rethink that, since only 1.1% of people have displays with that kind of resolutions, height wise. http://www.w3schools.com/browsers/browsers_resolution_higher.asp Even if you actually mean x1200, that still only bumps the available users to 4%, meaning whatever target audience you have are unlikely to be able to use the program.

Not at all. But I would think you'd still need some kind of micro controller to detect positions and decide when the whole thing stops. I won't link commercial sites here, but you can probably find the controllers themselves for something like $20 or so, then make the whole construction from that. https://www.google.com/search?q=schematics%20of%20a%20servo%20controller&aq=f&um=1&ie=UTF-8&hl=sv&tbm=isch&source=og&sa=N&tab=wi&ei=KpOfUYf0K4SI4ASCloHQAQ&biw=1093&bih=1071&sei=OpOfUdDyOMeE4ASpxIGICg Perhaps it's possible doing it more from scratch, but that would be far beyond my knowledge unfortunately. Another link I found and skimmed through, which might be of interest: http://www.audiworld.com/tech/elec142.shtml

Just remember; if someone is mad at you, nothing ticks them off worse than being super polite to them.

What are some cheap metals/ plastics that are heat resistant?
pwagen replied to jelowry87's topic in Engineering
There are tons and tons of materials that are heat resistant, especially at such relatively low temperatures. If you give a hint on approximately what you'll be making, that should probably narrow the list down a bit. Other things to take into account would be how easy it is to work with, toughness, hardness etc. As for paint, there are a lot of paints used for coating engines that are very very resistant, cheap, and easy to get your hands on. Your local car part supplier should be able to to supply you with some, or at least point you in the right direction. -
Sounds like you're looking for something like this. http://en.wikipedia.org/wiki/Motor_controller#Servo_controllers Also of interest would be this page, linked from the above. http://en.wikipedia.org/wiki/Servomechanism#Position_control

Sounds great. Can you describe your theory for us?

Power isn't measured in volts.

If that was true, China is about to become airborne. http://en.wikipedia.org/wiki/Ultra-high-voltage_electricity_transmission_in_China What kind of radiation does a flying saucer give off?

I'd hate to have that said to me.

Measure a lot (a LOT) from all kinds of people with relatives, then look for evidence in the statistics, of men with larger heads having female relatives with smaller heads and vice versa.

You'll need to show what you've done/tried so far. Nobody will do your work for you, but they are likely to help if you show you've made an effort.
