@goatsarah We've been tempted. Very tempted, but it's been OK so far.

OK, that's 10 minutes without a new account to approve, so I'm going to bed.

See you all in about 8 hours.

Cheers!

@rodhilton Are you aware of the Gell-Mann Amnesia Effect?

An interesting and original (I think) puzzle from Micky Bullock.

"Last week Negligent Neil calculated length AC. He had forgotten to switch his calculator from radians to degrees but, fortunately, he still got the answer right.

"An inky splodge has now obscured the angle at A. Negligent Neil has forgotten what his answer was for length AC, but he insists it was between 40 cm and 50 cm.

"Find length AC to 3 significant figures."

@4raylee Yup, or 44.1 to 3 sf.

Nice puzzle?

@OscarCunningham "Rounding to Even" will mean either 44.0 or 44.2. The value 44.052 is closer to 44.0 that it is to 44.2, so I'm not sure why you say it doesn't round to 44.0.

44.0 < 44.052 < 44.2

Differences 0.052 and 0.148.

@yetiinabox Well, I co-authored a paper on juggling with Joe Buhler (and Ron Graham and David Eisenbud)

Is that relevant?
