F = ma, where m is "fk all". The insect kingdom in general has little to fear from falling.
same reason they can only get so big? As in not really that big?
that's because they don't 'breathe' they just get air through holes in their exoskeleton

a bigger creature wouldn't get enough air
I understood that because insects have exoskeletons, their skeleton makes up a far larger proportion of their mass than it does in mammals by way of comparison, so their is a natural limit they reach before they would collapse under the weight of their skeletons. Limited by design if you like.

There was that, and also some link to oxygen levels it was believed, as seen by the massive carboniferous dragonflies, but the link isn't perfect, so under some doubt.

Looking a bit baldy





Now it looks like arse hair

Is that a Rooney? Or a Brucie?

Either way, it's not very convincing.

Baldies always over egg themselves when they get a transplant, it goes from "well, now you mention it, you do look a little thin on top, but I never paid much attention" to "what's that thing sitting on your head?"

I can only take a guess as to where the transplant came from.

We haven't - take Einstein, he was was a theoretical physicist, he was a very famous one, but there are a hundred or so prominent theoretical physicists working today a mere generation later, including Stephen Hawking. He's thought to be even more brilliant than even Einstein.

In terms of why we don't see the huge leaps in comprehension, IMO is simply down to the fact that despite the huge advantages Hawking has over Einstein in terms of computer power to help him, the most important bit is the mushy bit between his ears and that hasn't changed since Newton was trying to do the same as Hawking does with a super computer with an apple and it's not enough to overcome the law of diminishing returns.
Thanks, but that leaves the question why does a brain of such capability come along so infrequently? Einstein was recognised within his lifetime as a one off, I don't think Hawking reaches that rarified atmosphere with his theories quite so much.
Stephen Hawking is not that brilliant he can’t ever ride a bike

People are being vilified and reviled for jokes about a dogs home yet this goes uncommented.

Not having a go at you red rider, just about 'odd' standards hereabouts.

It also depends in which areas of specialisation you are looking. This guy is pretty bright, but I imagine less than 0.1% of the population of the UK have ever heard of him;

http://en.wikipedia.org/wiki/Simon_Donaldson

- and I'd even attended the same school and never heard of him. He has been awarded the Fields Medal and was Wallis Prof of Maths at Oxford, but as for his work in 'four-manifolds' although very PH sounding is not actually exhaust related. Shame really.

What (if any) advantage does a flat head screw have over a cross head screw - or vice-versa?

I wondered this because what sort of vindictive cretinous moron supplies me with a fricking flat head so that I can stab myself in the hand multiple times.
The advantages to a cross head are surely obvious to anyone with an elbow that actually hinges - namely - the screwdriver stays put even when the angle of attack isn't exactly 90deg.

So I asked my professional boat-building father-in-law.
He hates flat heads too but admitted he had to use them because they are seen as more aesthetically pleasing apparently.

Why do cyclists - particularly the middle aged Lycra wearing £5k super lightweight bike brigade - have hard, razor sharp seats but still wear padded shorts?

Why not just get a nice comfy seat?

It's true. All the deaf cyclists I know are all dead. Just like all the drivers who listen to music in their cars. Or Lotus drivers and motorcyclists with earplugs.
(I wouldn't wear headphones on a bike but I think you have every right to...)

On the seat thing is seems to be because to get comfy on a saddle you need your seat bones supported so if you sit properly on a squishy saddle it starts off comfy but as it inevitably squashes down it is no longer supporting you properly. Whereas in your shorts it is held in place. Also - it isn't really for padding (it's very thin) - it's more to help with chafing (don't ask).

Continuing with the cycling theme....why oh why when out in packs do they abandon the highway code and ride along in some sort of tour de france swarm? Maybe 3 or 4 across and 5 deep?

I do respect their right to use the road in safety etc but why I see them pissing along the road like this I find jt hard not to think about a gruesome ending for them. Cyclecocks

I'm hosting the parents in Edinburgh at the moment, and my mum pointed out that once you get out of the centre there's a much higher proportion of bungalow type houses compared to elsewhere in the UK. I'd never noticed it before, but driving through lots of random areas in and around Edinburgh I noticed that she seems to be correct. Why might this be the case (if it's true at all!)?

A chum is up before the beak tomorrow for bashing someone. This twonk hid my jacket with my phone/keys at a birthday party, annoyed everyone and started sharking my mate's young niece.

One guy told him to shut up, another was so worked up he went outside and punched the wall to calm down. The third just picked a glass up and smashed it on his head.

Lots of blood and snot on the floor and this vile tit comes out looking like the victim. He IS a tt but my mate may go down for 2 1/2 years.
