This is quite cool. If you don't mind me using the comments here, I would need your opinion about something related actually. Recently I was looking at the Wikipedia entry for the Bekenstein Bound and it had the following (and what I thought was misleading) account regarding the Human brain http://en.wikipedia.org/wiki/Bekenstein_bound :

"An average human brain has a mass of 1.5 kg and a volume of 1260 cm3. The energy (E = mc2) will be 1.34813×10^17 J and if the brain is approximate to a sphere then the radius (V = 4πr^3/3) will be 6.70030×10^−2 m.

The Bekenstein bound (I ≤ 2πrEħc ln 2) will be 2.58991×10^42 bit and represent the maximum information needed to perfectly recreate the average human brain down to the quantum level. This implies that the number of different states (Ω=2^I) of the human brain is at most 10^(7.796405960701×10^41)."

While this is cute and represents an upper bound, it immediately struck me that it was misleading as this would hold for

*any*sphere of that size and hence the "emphasis" on a brain was sort of to get attention and I put it on hold. Do you think it deserves to be put back and if so how should it be reworded or introduced because certainly it is not clear how many states an actual brain could take and the Bekenstein bound might be off by quite a bit?
