Wikipedia : Gadget / proposals has a few gadget proposals ( such as the log table and metadata scripts ) that have been there for quite a long time with no objections, some support, but not many people commenting.

Of course, the concept of logarithms is not hard to derive, even for an elementary mathematician, so it is possible that Muslims used log tables, but this is my best source, and I would try to stick with verifiable sources if you can.

I went on to learn ( not very well ) log tables ( and on entering industry ), slide rules ( " which, over forty years on, still work without having their batteries replaced even once " ) and then big desk top calculating machines with nixie tube displays.

In 1703, Magnitsky also produced a Russian edition of Adriaan Vlacq's log tables called " " 01; 8FK; > 30 @ 8D < > 2 8 A8 = CA > 2, B0 = 35 = A > 2 8 A5 : 0 = A > 2 " ( Tables of logarithms, sines, tangents, and secants ).

:Of course that conversion into powers-of-10 format is a bitch to do-but they published big, thick books ( " log tables " ) containing the logs of numbers from 0 to 1 ( to perhaps 4 to 7 digits of precision ) and other big books that did'antilogarithms'that convert from the log back to the normal number.

You could take the log 2 10 and suppose that the half-life is 24 / 3.32 = 7.2 hours, but that's a fraught assumption since there could be many sequential steps the molecule goes through that impose various delays so that it doesn't pee out according to a log table . ( I suppose even saying " half-life " already wades into these issues, come to think of it ) In any case it would be OR; stick to what the paper says . : ) talk ) 13 : 34, 17 January 2015 ( UTC)
