....certainly no need to appologise to me.. . Here's one.. 'if a bear poos in the woods and there is no-one else around - does it still make a smell'?

Yes - it brings me back to the stupid question of "if a tree falls in the woods........ etc.. BS, BS... would it still make a sound?" Ans: Of course it would you plonker! Aren't some of these 'philosophical' type questions made up just to stir debate, to practice argument, and to annoy the hell out of scientists?? QUOTE: OP As Aristotle said: That which is in locomotion must arrive at the half-way stage before it arrives at the goal. - What about an electron going from n=1 to n=2. No halfway there - just one quantised leap the WHOLE way.

I agree, but I must admit, I do use my memory of a running track to visualise 100m (that's valid actually as it is 100m, but you get the point I hope). Visualising football pitches or tennis courts is actually quite a good way of estimating/visualising ball park areas. I bet if you said to the average Joe 'visualise 4500m^2' They would say 'WTF??' Whereas if you said 'it's about one football pitch, they would understand. Perhaps this is where the saying ' its just a ball park figure' comes from.

What end zones? Or are you talking about that game where they wear body armour, pick the ball up with their hands and stop for a rest every 30 seconds? They should try Rugby mate - mud and blood - no resting, no armour.. Also, what is it with base ball? We have a game similar in the UK called rounders that the girls at primary school play. The real men play cricket! This suggests that a propper footbal pitch can be between 90 to 120m.

Have you (or anyone else) ever seen 'Look Around You' ?? I prefer the 1st series. It's done in a very dead pan way in the style of the old 1970's open university programs. The science is of course - completely off the wall and a load of crap, but it is presented as fact with experiments to back it up. They come up with some interesting versions of teh periodic table... Vey funny.

GIRLS ARE EVIL - Mathematical PROOF!: 1) Girls require Time and Money so: Girls = Time x Money 2)we know that Time = Money so: Girls = Money x Money = Money2 3)Money is the root of all evil (Money = sqrt-Evil) Therefore: Girls = (sqrt-Evil)2 4) so finally it is proven: Girls = Evil .................................................................

I've not been a member here long, but I reckon your question will get more feedback on one of the following sites: http://www.eng-tips.com/threadforum.cfm?lev3=57 http://www.corrosion.com/corroforum/default.asp http://www.coatings.de/fcforum/forum.cfm http://www.chemicalforums.com/ The first 2 are US based forums for professionals. I think that the 3rd one is mainly europe (?). and the last is mainly kids doing their homework, but it has a subforum for professional contacts. I hope this helps.

What if the coins were mearly damp when frozen. This would stick them without all the expansion if they were simply moist rather than under water. Setting in Urea Formaldehyde resin or any clear glue would look good, but it's a bit permanant.

I once saw a 2.5 L Winchester bottle of this stuff just break apart into 3 bits on the bench. It really made the guy who was using it jump. He was about to open the bottle and before he even touched it it just fell apart! About 1.5L of diethyl ether spread accross the bench and floor. It looked really weired - like looking through intense heat distortion as the stuff evapourated. Guessing their was a weakness in the bottle and the stuff had got warm (sunny day you see) and pressure had built up thus cracking the bottle. Very dangerous - good job there was no bunsen alight! I stood by the door getting fresh air and kept an eye on him (in case he passed out from the fumes) as he was cleaning it up.

Yea I liked the bit with the rats. Drifting a bit of topic here I think, but pertaining to the experiment in the video, I had a similar experience in a car just after passing my test (I was 18 and a bit of an idiot) - I went round a roundabout in a rear wheel drive car in the wet - I thought it would be cool to accelerate out of the roundabout hard so the back end of the car would just drift slightly on exit (what a div - I thought it would impress my mate). Anyway - needless to say the car span (In my defence I made sure there were no pedestrians or other cars about) - during the spin time slowed down such that me and my mate had a conversation about how stupid it was that I had tried this and decided that we were certainly going to crash. Luckily we just came to a halt and drove off a bit embarrassed.

Would you not get attracted to the sides of the hole at hit the closest one? Or are we assuming we are going exaxtly down the middle?

That was quite a cool video - thanks. QUOTE IA "i don't think it would be safe to drive even if you were only slightly high." .... or tired, or ill etc......

Yea - OK, if you were THAT monged out then maybe, BUT () - just to play advocate here - I rekon that if driving a real car your subconsious might sharpen you up a bit due to the real dangers of being killed if you make an error. You knew that you could crash your playstation car and not hurt anyone so so your subconsious, stoned brain placed a lower priority on being able to drive as well as normal. If going at a measly 30 mph arround normal roads instead of a race track, you may have been alright. ( I still don't suggest you try it though) QUOTE - from link I posted: "Results :-All subjects were able to complete the series without suffering any untoward reaction while driving. Data from one female subject were excluded from the results because no drug was found in her plasma after smoking. "

Agreed - but NOWHERE near as much as when under the influence of alcohol - it really is just a fraction where with alcohol you are talking multiples. (as I said before it sometimes seems that way due to the increased parinoia). (PS - I am not condoning dope driving at all - I am just saying that compared to drinking and driving it is nothing like as bad.)

You thought they did! They probably wern't as bad as you percieved them to be. That is the whole point of my argument. INOW "Not sure why, but your statement (likely not very accurate) reminded me of this from a Michio Kaku presentation:" I will watch it with sound when I get home tonight. Why wouldn't it be accurate - I read it about 3 years ago in the New Scientist. They were doing an article as to why you shouldn't drive when stoned. I thought they missinterpreted their results. I'll look it up for you when I get home.

The person who dug the hole would shout 'MIND THAT BIG F@#;ING HOLE!!' and after you fell in he'd say 'what a dick!' :D:D:D

My 2p: - (figures are rough quotes from memory until I look the article up and give you the facts). Alcohol - seriously reduces reation time by a mile (cant remember exact figure - half to x3 or more if really drunk?) - INCREASES confidence and risk taking by miles. THUS - you drive more dangerously, taking more risks and are nowhere near as capable as you think you are! THC - reduces reaction times SLIGHTLY by about a tenth (Obviosly not good - but NOWHERE near as bad) - DECREASES confidence so you drive more carfully. THUS - you drive well within your abilities, stick to the speed limit and are alot more curteous to other drivers. -- SAFER! The case against dope driving is that it reduces your confidence and slows reaction times - seems valid. However, in comparison, if you are driving more carefully due to reduced confidence / increased parinoia, but are only alittle slower (10%) then you are LOT safer than the drinker (or in fact a tired/ill person or someone using a mobile phone). An experienced driver/doper is alot safer in my book than a completley sober person just out of their test who thinks they are invincible. Most accidents happen in the first year or so of driving. 2ndly! Football hoolagans! They drink 10 pints and start fights and riots! Give them 10 splifs and see how many fights they start then! Notice that when the Brit footie hoolagans went to Holand there was absolutly NO violence at all.. I wonder why??

yea right! I knew a guy with 3 nipples at school - he never got laid either.

IIRC from watching David Attenborough, the fork in the tongue allows the snake to sense direction as well as smell/tase. It picks up scent through tasting the air - the fork gives it 2 refference points with one being more potent than the other so it can tell which direction it's prey went.

I'd go for fatalistic.

Hmmm.. what about the Venus Fly Trap? Or Triffids even?

I think Terry Pratchett has a computer called Hex made from an ant collony and mice in the wizards tower in Ank-Morpork.

http://www.billionheartbeats.com gives a brief overview. Type 'billion heartbeats' into google for loads of stuff. -- I havn't read any respected scientific journals regarding this but there is alot to suggest that it is a good approxination. Humans however go way beond their billion heartbeats (science cheating nature??) - we get about 3 billion according to the pages I read.
