The Serious Question Thread

Some trains have streamlined fronts, Bullet Train, TGV, Pendalinno's even Mallard!!

It's the long-distance trains that have streamlining, so I guess it must be viable for them to lose the cabin space. (ie fast trains on OneRail, but not the ones that stop at every station) Of course for the Mallard, it doesn't really make a difference since they sat right at the back of that great engine.

Every design is a compromise.

Yes, that summarises pretty much every machine in the entire world. It just always seemed strange to me.

The long-distance trains are streamlined because they are faster than the commuter trains. The faster the vehicle, the more benefit you get from streamlining. Remember that drag increases with the square of the speed. That's why buses can be like bricks; they're designed to go slow. Hence the balance: drag reduction benefits (small) outweighed by cabin increase (significant). Compromise agreed!

series 60, your basic smartphones,
series 80, Nokia Communicators
series 90, Nokia touch screen phones

SonyEricsons seems to be using it's own operating system.

If I went back in time and killed my grandfather, would that mean I wouldn't be born, so I couldn't kill my him, but then he would live, so I would be born, and I could kill him, so I wouldn't be born...................................

[janneppi]

Perhaps.

Time travel is impossible. Dont ask me to explain why, as its a massive discussion Ive had too many times and dont want to go into it now.

But ya cannae do it captain

[Brown, Jon Brow]

It is possible to go fowards in time, because at speed time goes faster. So if you went on a space probe at close to the speed of light, 1 year to you would be several years on Earth.

Jonny, you're a young fella, don't worry about time travel and stuff. Live in the present moment.

I actually had a question too.

Is it allowed (in law) to shoot to air with a gun? What if the bullet hits a plane? A para/hangglider? A bird? NASA's newest space shuttle?

[Brown, Jon Brow]

There is quite a lot of sky to aim for the chances of hitting something are quite small.

It will depend on the law of the country you are in
