Is it me or are summers getting hotter and hotter.
Not consistently hotter and hotter but certainly they tend to be hotter than before.The MET office has records going back to 1910.
The 5 hottest days in UK history were in 2019, 2003, 2020, 1990 and 2013.
The longest heatwave in UK was 2018 and we're seeing generally higher than average (since 1910) temps routinely every year.
That's not to say we're moving towards a consistently warmer / sunnier climate, just more extreme, last summer, despite being very warm at times, we also the wettest in history and in 2012 it rained every single day from May until September.
For my entire childhood I dreamt of a proper snowy winter, but it only ever happened once, in 1982, for nearly 30 years it hardly ever snowed again, we might set a few mm and we'd run to the shops to buy bread and milk because that's what you did and school would close for no good reason and you'd head up the hill on anything flat you could find to ride down it because it all melted mid-afternoon. Then, bam, suddenly in 2010 it really snowed, then again the next winter, and the winter after that. Winter tyres have become a 'thing' in the UK Now and it seems most winters we'll have at least one day of 'proper' snow.

I only said "info based on South Wales" so all the Scots on PH didn't jump on me for the Snow references.

1987 was pretty bad for me in Cheltenham. The snow was piled up taller than a Transit van on the sides of rural roads (I have photos somewhere) and I remember it because my driving test was cancelled twice that year due to snow. However, I have not seen snow like that since.

It definitely feels like there are more hot days above 30c every year than there have been. I remember thinking that 25c was hot, now I wish for it.
It's 34 in London right now, and has been above 30 for the past week. That seems to be happening more often, even if the extreme temps aren't.

What prevents an engine running backwards?
Not as in reverse, I mean as in the crankshaft moving clockwise when it should go anti-clockwise or vice versa.
Is is just the way it is spun on start-up ?
Can a normal engine be run the wrong way?
The timing would be all wrong.Not as in reverse, I mean as in the crankshaft moving clockwise when it should go anti-clockwise or vice versa.

However some engines can, and do, run in reverse.
Steering it wasn't too easy though!

Supposedly there was a micro-car that you had to stop the engine and start it the other way to get reverse.
The Bond Minicar had a motorbike engine and gearbox, hence no reverse. But you could indeed start the engine to rotate in the opposite direction to normal and hence reverse the car. It meant switching off and back on again each time you changed from forward to reverse or vice versa.vonuber said:

I believe that whilst the average temperatures over the course of a year remain largely the same, the peaks and troughs around that average are becoming more extreme. It's 34 in London right now, and has been above 30 for the past week. That seems to be happening more often, even if the extreme temps aren't.

It just wouldn’t run because the timing would be out.Not as in reverse, I mean as in the crankshaft moving clockwise when it should go anti-clockwise or vice versa.

However, years ago a truck engine manufacturer ( could be Gardener ) made a two stroke diesel for lorries that could run backwards, this usually ended with them over revving to destruction.
But a four stroke engine, no.

Some numbers are based on distance (from road start) rather than property e.g. 1500 could be 1.5miles from whichever end of the road is defined as its beginning.

This is done in New Zealand. 1500 would be 15km from the start of the road. This makes a lot of sense in rural areas as chances are there could be a house built between you and your neighbour a few km down the road. Otherwise your house number of being something like number 12000 on State Highway 1 could end up getting shuffled up every time someone builds on a plot on the other island. I think in practice, if a big development or a town is on the main road, that section will be given a road name and a set of numbers. This happens often as to save building more roads, a lot of smaller towns are mostly developed along state highways, so any long road trip involved going through the middle of dozens of villages and towns.

Why did all this stuff happen on this rock in space? Is any of it real?
I mean, what even is 'real'?
A near infinite number of independent physical actions timed to such coincidentally timed perfection as to be beyond fathomable. Attempting to make the unfathomable, fathomable has divided man since we first started to think about it.I mean, what even is 'real'?
Where were all the atoms and such needed for the Big Bang then?
Are we in a computer simulation? Were the atoms developed/kept in a beta universe, on ice so to speak?
I might start a cult to find out.
What finishing product do manufacturers put on cotton shirts to make them feel soft when new? After a few washes the wet cotton sounds like a flapping sail on a boat and I know when dry it's going to turn to cardboard with lots of creases. Poly/Cotton mixes are far superior for lazy sods like me with no irons but I prefer the 100% cotton experience.
