Favourite numbers

Postby Cyril Haearn » 30 Jan 2020, 6:44am

I like numbers, they have a lot of meaning, zip codes, STD numbers, heights on OS maps [imperial AND metric for many of this parish], Naismiths Rule, old milestones, distance from Charing Cross, chainrings and sprockets, gear ratios, spoke length calculators, dates, birthdays, road numbers, why, does not The Motorway City of the Seventies sit on the M666?

597 is one of my favourites, which is yours?

This year 85 has some significance as it’s the height difference in meters of the hill I am using to benchmark my return to fitness.

Back on two wheels in deepest Pastyland and loving every minute. Mission: to enjoy big, bad hills again.

It was the age I retired and was then able to cycle as often as I wanted. Pesky job always interferred :lol:

No: it's not really any sort of 'favourite' of mine - I just wanted to show off how many digits I could rattle off from memory... 8) :oops:

Touring on a bicycle is a great way to explore and appreciate the countryside and towns you pass through. Make a difference...

Another one: I've long been amused by contemplating Graham's Number - a number so vast that it cannot be represented in any conventional manner - not even if the entire volume of the known Universe were filled with memory chips - let alone paper. Nor even its logarithm, nor the log of its log, etc. etc.

Nevertheless the last few digits of this number are known, they are: ...262464195387. How these mathematical wizards know that, I'm baffled...

I can understand gears, distances, weight, but whatabout population per square kilometre? Is 39 people per km2 high or low?
