Expansion ideas / Move to Orders of magnitude (entropy and information) ?

Nice new page idea.

Thinking about where to take it, what would people think of widening to the above (and also changing the reference unit to the bit), to include measures such as the capacity of a CD, DVD, Blu-Ray, the first stored-program computer, the first hard drive, etc; the quantity of text in the Library of Congress (if ASCII coded, and excluding illustrations), and its annual growth, etc; the estimated size of the accessible internet (5 million terabytes = 4 × 10¹⁹ bits, according to Google's Eric S. Schmidt in 2005 [1]); as well as chemical/physical quantities like the entropy increase if one joule of energy is added to a heat-reservoir at 300 K (0.0033333 J K^-1 = 3.4831 × 10²⁰ bits; the configuration entropy of a mole of a noble gas at STP (eg Neon 146.33 J K^-1 = 1.5291 × 10²⁵ bits) [2], or an average 25.391 bits per atom); the standard entropy change for a mole of one or two interesting reactions, etc ?

Perhaps also add 1 deciban (0.03 of a bit) -- according to I.J. Good, about as finely as humans can reasonably comprehend the weight of evidence for or against a hypothesis. Jheald (talk) 10:58, 20 April 2010 (UTC)Reply

Hmmm. I see there is already Orders of magnitude (data). I'll try adding some of the items above there. Jheald (talk) 14:04, 20 April 2010 (UTC)Reply

Isn't it redundant to have pages about both data and entropy when the two are so closely linked?108.18.223.72 (talk) 01:11, 9 September 2011 (UTC)Reply
