I thought this might be of interest – a brief investigation into what factors helped bring about the invention of bikes: https://rootsofprogress.org/why-did-we-wait-so-long-for-the-bicycle

I find this map – London, 1806 – endlessly thought provoking
It’s of a scale & level of detail where you can mentally walk (cycles have yet to be invented) around it.
This was the London of Jane Austin & the Napoleonic wars – A world were steam engines were rare & lumbering beasts and most power was provided by muscle (human or animal), wind or water – A world of wood, wool, cotton, hemp & blacksmith crafted iron.
It’s quite possible for someone to have been born into that world & in their dotage held in their arms a child who would see the moon landings.
The Apollo landings – as
The Apollo landings – as reported by James Burke, are I’m fairly sure my earliest memories.
(Am I right in remembering that the BBC’s broadcasts used Straus’s Also Sprach Zarathustra as an intro?)
Of that period I rather like this (possibly apocryphal) quote from a surprising source
“Brian Eno once confessed that he liked to explain to ‘young people’ that, back in the bad-old-low-tech-flared-trousered-analogue days things were so backward that you could fly from London to New York in three and a half hours and men regularly walked on the Moon.”

To be fair there are a number of outtakes where he fluffs his lines and they have to get the rocket back for another take.

The basic principle is the same – combine an oxidising agent with a reducing agent to expel mass at great speed.
Whilst we’re off topic, here’s a bit of James Burke reporting on Apollo 11 (the BBC wiped or lost most of its broadcast):

For a randonee through the evolutionary pathways of the bi/tri cycle “Bicycle Design: an illustrated history’ (Hadland & Lessing): https://mitpress.mit.edu/books/bicycle-design makes for an entertaining guide.
One of the things that it demonstrates is how ideas appear ‘before-their-time’ are then forgotten until they reappear when conditions are rather more propitious. Using designs that were appearing at the time it would have been possible in the later 1890’s to have produced an aluminium framed bike with full suspension & disc brakes ~ something that needed a century to pass before it became a marketable reality.
Thanks for those recommendations – I’ll see if I can add some more books to my ever expanding reading list.
I’d put James Burke’s Connections into the pantheon of ‘Great Television’ and a special mention has to be made of possibly the greatest shot ever in TV journalism. No green screen, no special effect, just one chance to get it right if you have the most incredible timing:

I did read somewhere (can’t remember where) about how the Romans could possibly have invented bicycles much earlier, but obviously didn’t. There was mention of how Roman roads often had two smooth grooves in them to allow cart wheels to travel easily and a bicycle would be a natural shape (as opposed to a tricycle) to also use one of those smooth ruts.
By the way, the most important application of clocks was navigation – the easiest way to determine longitude is with an accurate timepiece.
Incidentally, if anyone is interested in how developments in one area spur developments elsewhere, then I can thoroughly recommend James Burke’s Connections series: https://www.youtube.com/watch?v=XetplHcM7aQ

The design uses a suprisingly modern looking chain drive which to me makes it particually iffy.
