In addition to the space stuff- how much difference does a Jockey make?
A lot.The jockey decides on where the horse is going to be during a race, maybe sit at the back, maybe keep in front, etc.
The jockey will also know when to start 'geeing' the horse up as the finish approaches to get the best from the horse.
The jockey will also know the best path to steer the horse through the pack of other horses in the race.
Hence why some jockeys can make millions from their trade.

Surely all you need is a light guy/girl who can sit on top of a million dollar horse with centuries of breeding and not slow it down?
I guess he may need to beat the s
t out of the animal without it getting too pissed off or dying on the course- is that a Jockey's main actual skill?
Yep. Same as Formula 1. No need for a Lewis Hamilton, surely anyone who can drive a car could do it. Just do what they tell you over the radio and you'll win :-)Surely all you need is a light guy/girl who can sit on top of a million dollar horse with centuries of breeding and not slow it down?

A horse needs a jockey and a top horse won't win without a top jockey.

Apparently that's happened before, however the problem traveling so fast so low is that the atmosphere burns it your payoad up. My mega-spring seems to be a non-starter unless I could maybe mount it on Everest. I'll give Elon a call.

If you can't adjust to these incredibly minor differences then, frankly, I'd rather you weren't on the road at all. (That's a general "you" rather than a specific accusation BTW).
people do get het up about indicators on the left or the right though, don't they?

Also, right hand dominant people (right-handed) are usually totally inept at the simplest things with their left hand, with no dexterity, yet no one struggles changing gear with their left hand. Its not the hardest thing in the world granted, but does anyone (perhaps even learner drivers) ever even think about it being a problem using their left hand to change gear? Seems not.
A little tongue in cheek but i'm interested none the less.
Which way do Wi-fi waves go?
For some reason our Home-hub router down stairs sends signals out really well to the rooms downstairs - but upstairs coverage is poor.
Our hotspot repeater that's positioned upstairs gets a decent signal to devices upstairs but also to those downstairs.
Do wi-fi waves run out of power and fall through the floor?

Person Whose Worst Subject Was Physics typing, please treat the following guesstimate with all the contempt it deserves:
I don't *think* they are the sort of waves that can really be affected by gravity at all, so no falling.
But they do have a range, and they get weaker and weaker at the edges of that range.
I know they don't penetrate (obligatory pause for schoolboy sniggering) though structure, walls/floors, terribly well, so it figures that any part of the house which is some combination of further from the router AND is through several layers of brick/wood/plaster etc wouldn't have great coverage.

It's funny, I''m right handed and live in the UK but I've always found it natural, with dominant hand steering. I find 2nd to 3rd delightful in a RHD, especially when pushing on, can't do it anywhere near as quick in a LHD. Slight pull seems so much better than slight push.Also, right hand dominant people (right-handed) are usually totally inept at the simplest things with their left hand, with no dexterity, yet no one struggles changing gear with their left hand.

I wish I knew, in the process of planning a Wi-Fi network for an office building, in answer to your tongue-in-cheek question they travel in every direction equally. Which way do Wi-fi waves go?

'Penetration' is the name of the game. Decent commercial spec Wireless Access Points are dual band, one band is good for speed, one is good for penetration but it's still very hard to look at some drawings and say "ah yes, I need exactly 3 WAPs for this, of this type, in this location" (well I'm sure some people can, but I can't) because some walls are just empty cavities, some are solid, some have pipework in them which causes problems for wifi and some are sound proof, which at least in this building are somehow completely impervious to wi-fi.
I'd guess your wi-fi router is a lower spec than your repeater.
Back on the topic of space and related matters:
Assuming the Earth's orbit around the sun is on one flat plane, is it possible for something to leave Earth's atmosphere and travel at a 90 degree angle from that upwards, into that bit of space? or would whatever we shoot out end up in orbit around the sun still?

Yes, given enough acceleration. The Pioneer and Voyager probes have escaped the sun's gravity, but all with gravity assist from Jupiter(?). I don't think we've launched anything directly away from the sun - probably not got a powerful enough rocket.Assuming the Earth's orbit around the sun is on one flat plane, is it possible for something to leave Earth's atmosphere and travel at a 90 degree angle from that upwards, into that bit of space? or would whatever we shoot out end up in orbit around the sun still?

What uses more leg power - walking up stairs or pedaling a push bike?
Cycling is more efficient than simply walking on the flat ( source) - so it would certainly use more energy climbing than cycling (and thus more 'leg power', almost regardless of how you define that).What would get you fitter, half an hour walking up and down the stairs of a 20 story apartment block or half an hour cycling?
You've changed the question by asking which would get you fitter, though. Doing the less efficient thing would get you fitter because you'd have to work harder to achieve the same result.

and that, in a nutshell, is what made me miss by 2% the distinction on the one all-of-the-sciences module that nearly all universities make everyone doing any natural science take. Presumably the effect over the sort of distance involved in a home wifi setup is pretty minimal?

I think the pattern of WiFi waves propagating from your router is to do with the shape / design / orientation of the aerial. As well as what it is near / the shape and construction of the house.
In similar way to having to carefully position an old-fashioned TV aerial (to receive, instead of to send AND receive).

Say a car was involved in a fatal accident and ended up properly mangled, what would happen to it other than be crushed? What would happen after the police retrieve it etc, and would it ever be sold on? E.g copart
Many cars ,but by no means all, involved in fatalities, murder,or serious crimes are treated as forensic exhibits ,they can remain in storage for many years .We had a corsa stored under wraps for 4 1/2 years in the garage that I worked for .The driver had deliberately used the car to cause harm and had also hit a postman who didn't recover from his injuries.
The car was retained until after the appeals were all dealt with .
A Jag E Type owned by one of the Great Train Robbers was held for many years by the police hence it's very low mileage when passed on many years later .
These days most with a fatality attached to the vehicle are crushed .
I used to work at a police barracks that dealt with serious or fatal crashes - one in particular I remember was a Mondeo (I think) that had been stolen, was being thrashed along an icy road - couldn't stop at the end, and launched itself about 20ft into the top of a factory wall (the factory was in a sunken industrial area), and stuck there.
It was still at the barracks 5 years later, all the occupants died. Car didn't look in too good shape either...
