Things that have bothered you for a long time.

When you have a clear open cycleway that stretches into the distance in both directions and is completely free of obstructions, the two pedestrians walking towards you and the one pedestrian-anna-dog combo that is walking in the same direction as you are riding always meet, thereby blocking the cycleway, just after you would have passed them, so you can't nip through the gap without causing them to panic, and instead have to slow down, let them pass each other, pass them, and then work back up through the gears?

Don't they allow vaporising rays in Germany like they do here then?

Why when whoever decided which way electric current flowed (I think it was Benjamin Franklin) did he get it the wrong way? And when they found out, why didn't just grasp the nettle and change it?

Why does mains current have to be bang on 50 Hz? Stuff like kettles don't care what the frequency is. Computers convert AC electricity to DC, so why would they care? What exactly needs to use 50Hz AC current?

Latin - why was it so much harder than every other subject at school? I did three years of it. I can't remember ever reading a Latin quote in a book and understanding it.

Why are checked trousers back in fashion? Haven't the younger generation heard of Rupert the Bear?
I have a pair, to go with a jacket and waistcoat. I bought it for attending beer festivals. I very rarely wear it in case people think I'm a self-gratification artist.

I saw a Rupert the Bear annual in WH Smith's. I thought Rupert the Bear was a bit surreal when I was young. It looked completely trippy now.

Blame Nikola Tesla. It was he who showed, and proved, that it works best. Much to the detriment of those who spent years trying to prove that 133Hz was better.

Range is 50-60Hz, not a steady 50Hz.

It's 60Hz in America. Here it's 49.5 to 50.5 Hz.
Blame the Germans!
"When the German company AEG built the first European generating facility, its engineers decided to fix the frequency at 50 Hz, because the number 60 did not fit the metric standard unit sequence (1, 2, 5). At that time, AEG had a virtual monopoly and their standard spread to the rest of the continent. In Britain, differing frequencies proliferated, and only after World War II the 50-cycle standard was established."

I wondered more why mains frequency had to be exactly 50Hz in the UK and not be allowed to decrease to 48Hz maybe in time of high demand. I read it's to do with keeping the mains frequency in step across the network, which I can understand (I think). Weird things would start happening electricity of different frequencies was transmitted along the same cables.
