Now we know that some people truly have "rocks for brains".

On a side note, Ear rocks and brain sand: why you really do have rocks in your head.

That talks about finding the decimal expansion of Pi by analysing cases where the ratio of the block's masses is a power of 100. Am I right in assuming you could find Pi in any other base by analysing collisions where the ratio is a power of base^2 (assuming the base is an integer>1)?

The "This is your brain..." ad campaign only goes back to the Reagan Administration.

Yup.

Think about it and it should be obvious. Hint: there is absolutely nothing special about base 10 unless you have 10 appendages.

Thanks. I thought it would be true, but was wondering if there was some non-obvious reason it would not work for all bases.

Which is 21-12-1221.

I don't see any palindrome there.

Oh, ISO format: 1221-12-21. Got it.
