From memory: 3.1415927 - as much as my teenage Casio calculator would display. 

Nobody was more surprised than I when I scraped a C at O level maths, but two things stuck with me, Pythagoras' theorem and pi to fourteen places thanks to having the following sentence drummed into me by the maths master: "How I want a drink, alcoholic of course, after the heavy lectures involving quantum mechanics."

I think of the excellent books by Mick Herron (and now excellent series on Apple TV - or so I am told as I haven't watched it).

Not come across those, noted for my next library visit! The other thing that particular sign always makes me think of is the incomparable Tom Waits and the line from Jitterbug Boy, later used as a title for a compilation album, "It's fast women, slow horses..."

How useful is the fourteenth decimal place of pi? Well, the thirteenth and fourteenth digits are 7 and 9, so you could drop the fourteenth and round the thirteenth up to 8. Doing so would result in a rounding error that, when calculating a circle the size of the equator, of about 0.12 nanometres - less than the diameter of some atoms.
Hardly worth the effort of drumming into any child's head, but hopefully Pythagoras' theorem comes in handy from time to time.

Why π^π^π^π could be an integer (for all we know!)

Pie to the pie to the pie to the pie?

Is that like one of them turduckens, but with pastry?

In a similar vein, a bar chart of how much of the door I've painted.

Of more interest is the scatter chart showing how much of the floor you've painted.

The Guardian do a nice line in Venn Diagrams.

Some kind of ratchet in that hub? It doesn't look like he can even push the pedal all the way to horizontal.

Ah - yes, they've got an American Star the wrong way round (means the child carrier needs rearranged though).  Or it could be a Facile but inverted?

Any one who knows Pi to 26 decimal places will have that off in 10 seconds.

I assumed it would be a large number and its prime factors.

You'd be wanting the Topology Department

He needs to get that rack bolt replaced too.

New leadership self-help book out from the Evil Cycling Lobby

I'm about halfway through 'Roads were not built for cars', and I hadn't realised how early on history, opinions, and the built environment were edited to create motonormativity.

Yup.  The more digging I've done the more the story changes from just "the market offered what people were calling for and they eagerly bought into it".  Just like the invention of jaywalking or the massive expansion of semi-trucks and "SUVs" (and auto-outrages like the leaded petrol scandals) this is more a tale of conscience-free marketing, corporate lobbying, tax dodging and rule circumventing, political machinations and ultimately the quest for power and vast accumulations of money.  (Gets even more murky when you throw in the important driver of the military-industrial complex).

Of course we are all "to blame" also - for all kinds of reasons beyond just their utility for transport people do want what motor vehicles now provide.

Stockholm Syndrome, between people and their cars, one of the American commentators was saying on X Twitter today. Active travel must be such a very lonely path to tread over there. 

You have to solve the Bonnie & Clyde problem to get people to give up their cars, "the I will, if you will" conundrum.  Let's see if I can remember - Bonnie & Clyde stole a car and used it to rob a bank. Police are holding them in separate cells.  Everyone knows the jail terms.

The police have enough evidence to convict both of them for the car theft - that's a jail term of 5 years each. The penalty for the robbery is 15 years each, but the police will need a confession from one or both parties as they don't have enough evidence.  However, if one informs on the other (who stays silent) the reward is that person goes free and the other one gets 20 years in jail. 

Put another way, everyone in the country lives in town A and they all work at factory B 10 miles away.  The bus service is pretty good and takes 20 minutes.

10% of the workers decide to get cars, which halves the journey time for them. Another 10% see this and also get cars - it's a little more than 10 minutes, but still better than the bus. Another 10% get cars and the bus timetable is amended to take 25 minutes and is slightly less frequent. Another 10% make the shift to cars - it's quicker for them than the bus. 

When we get to the 50% mark, the car journey is now 20 minutes - older workers remember the bus used to take this amount of time. But the bus is nudging half an hour these days, so another 10% get cars. Older workers again remark that it's all very well, but everyone used to get to work in 20 minutes back in the day, and that even the drivers cannot match this now.  But that memory has long faded.

It's not just a plain prisoner's dilemma or tragedy of the commons either - the authorities (heavily lobbied by the various industries and businesses concerned - which is apparently everyone down to shop owners) are not neutral. So it's not just "change society by changing a serious of individuals".

Again, I'd have written this off as like drying to drain the sea (given the feedback loops) BUT there are examples of not just "how it could be different" (NL) but also "you can get there from motornormativity and no cycling" (Seville).

I'd be interested in hearing more on this book. We're in Drivers and their Problems territory here.

You had to create the narrative that car mishaps were all "accidents" and treat accordingly, and always trivialise driving offences. It helps if traffic law enforcement is ridiculed for this reason. 

Queues of cars forming have to become a state problem for the state to solve - editing the environment is framed as improvement and progress.  The framing of public transport as old, slow, humdrum and inefficient must be a useful underpinning.

I wonder if it's just luck that air pollution made by ICEs is odourless and generally invisible, or if they had to work at that - if cars generated a smell of rotten eggs, it might have made a difference.  You have to work to suppress ideas around a link between air pollution from ICE and respiratory disease. 

I wonder things like the so-called Blade Runners are the result of an experiment gone wrong? 

People's Stockholm Syndrome becomes apparent in things like "don't live near a main road then; don't live near a school".

Part of the tragedy of the commons story is the passage of time, and lack of memory - I pass village bus shelters that stand as a memorial to a long gone services; you have to find timetables from the 1970s on EBay to see what has been lost. 

Old photographs (often put about by the "wasn't Britain great before it got invaded?" crowd), Post war Buildings (e.g. schools) with hardly any parking provision, "50 years ago" local newspaper features of a village fete sack race and childhood obesity practically absent.  Life was happily lived before mass car ownership.

Thanks. At 340 pages, I assume this is a bit more broad-ranging than the title might immediately suggest? ("Roads are for cars"/ "roads were built for cars", etc is of course a so what? / non-argument.)

Looks like there's some copies floating around, but I've just used my last 10s chain : https://www.amazon.co.uk/Roads-Were-Not-Built-Cars/dp/1610916891

He's quite big on detail!  You can get some of his work for free - for example his latest endeavor covering "when the UK's infra was (first) the envy of the Dutch" and what happened after that - the history of the 1930s cycle tracks, now online.
