Re: Order being born from disorder?-ERRATUM



Oops. I noticed a typo in my last megapost. I said:
<SNIP>
The conversion factors relating different entropy units are given as:
1 J/K = 1/(1.380658*10^(-23)) nat = 1/(ln(2)*1.380658*10^(-23)) bit =
1/(2^(38)*ln(2)*1.380658*10^(-23)) gigabyte.

The last line above should say:
1/(2^(33)*ln(2)*1.380658*10^(-23)) gigabyte.

Here ^ the 38 should be a 33. This is because there are 2^33 bits in a
gigabyte, not 2^38 bits. This error influences another number I also
errantly wrote in that post. Where I wrote:
<SNIP>
... so
much so that after the absorption it requires an extra 3.801*10^11 gigabytes
of information to specify the microstate afterward (this being equivalent to
an entropy increase of 3.356*10^(-10) J/K).

The phrase above that says "extra 3.801*10^11 gigabytes" should read
"extra 4082 gigabytes". The parenthetical 3.356*10^(-10) J/K is correct.

Sorry about that.
