Nobody here justified any of their claims other than by stating contradictory assertions (except maybe the first commentator 'On catching a cold'). Unless you had any direct contact with this type of knowledge (which I doubt), you all learned your 'facts' from somewhere, so if you're going to jump into this, at least take the time to check up your info and give your references. And this goes to the author of the article above all.

And this goes to Christopher: taking an authoritative, professoral stance to spray vain and condescending insults around is the oldest form of sophism. Worthless rethoric, where you attack the person itself instead of commenting their claims. You're giving bad grades to everyone? Why is that? What you're trying to do, it seems to me, is to refute by showing off, when you don't have anything to say. It's irrational and un-scientific. I'll go as far as saying that going public with your post is a narrow-minded manifesto for ignorance and dimwitness.

I don't have anything to say about the content of this site, partly because if I would give a fuck about it, I would check it out myself in books. But anybody can strip a text to its form and see what is really being said. In this case: nothing.
I'm just surprised nobody noted this before.

It's so easy to take a stance on the internet, especially one you would be ashamed to take in public (or one that would simply bring you lots of unnecessary trouble). Most people who do it only contribute to making this source of information more unreliable than it already is, which is pretty fucking sad, considering the incredible potential of the medium.

I never commented on blogs before because their contents are, in my opinion, more often than not, worthless. There are some refreshing exceptions, though. But here I stopped to read because we have a text which aims at CORRECTING common scientific knowledge, followed by what could have been a real debate. I hoped I would learn something. I expected a more solid form of argumentation than simple undocumented assertions and vain commentaries that take all their force from their thickness and agressivity.

Oh well, too high expectations I guess, than to hope people would behave in a civilised and rational manner.

Here, that's my take. In the hopes that it would find some echo. Oh, and should you feel the urge to correct my spelling or grammar, I'd like to say right away that english is not my mother tongue. I'm still learning, everyday. My apologies, I hope this is still understandable.

Cheers!]]> Thu, 22 Jan 2009 08:54:58 +1100 http://www.dailycognition.com/index.php/2007/07/09/10-science-stuff-you-got-wrong-at-school.html#comment33
spongekill - being "a thousand times more likely to get a cold walking around in the snow in your underwear than staying indoors by the fire" is complete nonsense.

Your wrong. Being in the cold while in nothing but underwear WILL increase your chances of getting a cold granted the virus is present.

trev - you are right about the speed of light. only in the vacuum of space where there are few resistances can light reach its max of roughly 186,000mps. In all other cases the speed of light varies greatly depending on the matter it is passing through (as low as about 30-40mph has been recorded).

spongekill - being "a thousand times more likely to get a cold walking around in the snow in your underwear than staying indoors by the fire" is complete nonsense.

however the germs that make up the common cold do thrive in colder temperatures, but that does not mean simply being cold gives you more chance to catch a cold since you need to come in contact with the germs in the first place. being out in the snow in your underwear makes it more likely you will end up with something more serious than a mere cold!]]> Sat, 10 Jan 2009 00:23:31 +1100 http://www.dailycognition.com/index.php/2007/07/09/10-science-stuff-you-got-wrong-at-school.html#comment31

Black Adder: yes, all meteors are formed of rocks. many commets or formed of mostly water/ice and rocks

Yaa101: you've been reading too much New Age psuedo-science and you have no idea what you're talking about

Kurt: you are a Young Earth Creationist which means you know less what you're talking about than Yaa101

The moon: the space shuttle never goes behind the moon, only apollo astronauts did that. Earth satellites also do not go behind the moon and the objects that have gone out in the solar system to send us back wonderful information are not properly called "satellites" in most cases but "probes". technically, a "satellite" is simply an object that is in orbit around another (larger) object.

While you're point on electricity is correct, flow is extremely rapid whereas movement of electron is not... but that doesn't necessarily define electricity, it's the flow of charge, not physical objects.

You won't get a cold from JUST a low temperature, but the lowering in temperature, can cause various proteins involved in immune response to behave differently/slower. However that is largely peripheral. If core body temperature drops, many problems with defence enzymes not working correctly will have a big impact.

Erm Yaa101, nice concept but I think you really don't get physics at all.

That is just plain incorrect. A great many space missions go beyond the Moon's orbit--how do you think we're receiving all those lovely Martian photos? Magic?

How about satellites which monitor solar weather, positioned roughly halfway between the Earth and the Sun?

Although individual electrons can have a very low drift velocity, electrical current is actually an electromagnetic wave and propagates as fast as any other emf in that conductor (i.e. it travels as fast as the speed of light in that medium). Note that be saying electricity is caused by an emf, this immediately means that it is composed of photons. This emf determines the "speed" of how fast electricity can be transmitted across a wire and, as stated in other comments, is related to the dielectric constant, and is exactly the speed of light in the medium of conductance. It is, however, fair to say that electricity travels slower than 'c', or the speed of light in a pure vacuum.]]> Mon, 15 Dec 2008 19:13:31 +1100 http://www.dailycognition.com/index.php/2007/07/09/10-science-stuff-you-got-wrong-at-school.html#comment13 Mon, 15 Dec 2008 09:53:40 +1100 http://www.dailycognition.com/index.php/2007/07/09/10-science-stuff-you-got-wrong-at-school.html#comment12

As space shuttles and satellites pass behind the moon, the moon becomes an obstruction between the earth and whatever is passing behind it. In the case of a space shuttle it would "go dark" indicating that we could not have radio communications with it.

Light does travel. When you get into quantum physics electrons and light share properties of matter and waves. Light can travel, seemingly as a particle, through empty space, and can also refract and reflect like a wave.

Electrons can also does not behave exactly like a particle of mass would be expected to. This is called wave particle duality and is detailed in the double slit experiment here:

Electricity=Light=Sound, just at a different frequency and this frequency plus fase determines the pace of contamination besides the material it contaminates through.
Light does only seem to contaminate with good rendement through gasses, somewhat less through fluids like water, even less with non conducting fluids and does hardly contaminate through solids.
Electricity contaminates best through conducting solids and fluids and less through gasses, although nowadays batteries of computer mice are feed with the energy of the signal that travels between the tranciever of the mouseport and the one on the mouse.]]> Sun, 22 Jul 2007 02:01:53 +1000 http://www.dailycognition.com/index.php/2007/07/09/10-science-stuff-you-got-wrong-at-school.html#comment6 Sat, 21 Jul 2007 10:22:08 +1000 http://www.dailycognition.com/index.php/2007/07/09/10-science-stuff-you-got-wrong-at-school.html#comment5 Sat, 21 Jul 2007 10:21:42 +1000 http://www.dailycognition.com/index.php/2007/07/09/10-science-stuff-you-got-wrong-at-school.html#comment4 Sat, 21 Jul 2007 07:42:21 +1000 http://www.dailycognition.com/index.php/2007/07/09/10-science-stuff-you-got-wrong-at-school.html#comment3 Sat, 21 Jul 2007 07:41:46 +1000 document.write("Black Adder"); ]]> http://www.dailycognition.com/index.php/2007/07/09/10-science-stuff-you-got-wrong-at-school.html#comment2 That's not the claim.
