SEQS with subject matter from Biology, Chemistry, Astronomy

[Jonathan Post]

There is no good reason to have a SCI keyword for Science.  However...

There are some seqs which are clearly from subject matter in  Biology (other
than Fibonacci's rabbits), Chemistry, Astronomy (other than calendars),
Physics, and the like.  For instance:

Astronomy:  A111050 <http://www.research.att.com/%7Enjas/sequences/A111050>
 Relationship between the planets' orbits and a simple mathematical number
sequence.

Biology:  A104155 <http://www.research.att.com/%7Enjas/sequences/A104155>
 The 64 codons of the genetic code, giving the value 1 to thymine (T), 3 to
adenine (A), 2 to cytosine (C), and 4 to guanine (G).

Chemistry:  My newly submitted example below, and such as:



  A007656 <http://www.research.att.com/%7Enjas/sequences/A007656>
 Atomic weights of the elements.
Physics: A003678 <http://www.research.att.com/%7Enjas/sequences/A003678>
 Decimal expansion of speed of light (m/sec).
 A003676 <http://www.research.att.com/%7Enjas/sequences/A003676>
 Decimal expansion of Planck constant (joule sec).

%I A000001
%S A000001 1, 5, 12, 21, 31, 43, 57, 73, 92, 112, 135, 160, 187, 215,
246, 278, 318, 353, 392, 432, 477, 525, 576, 628, 683, 739, 798, 857,
920, 986, 1055, 1128, 1203
%N A000001 Rounded partial sum of atomic weights of first n elements.
%C A000001 Since, for sequences of reals in general, the rounded value
of a sum is not equal to the sum of the rounded values, this sequence
is not identical to a partial sum of A007656 Atomic weights of the
elements. See also: A070217 Numbers not represented by a known atomic
weight. This relates the the question: "what is the mean atomic weight of a
dilute plasma of monoatomic elements with atomic numbers 1 through n."
It is poorly defined, even with the caveats of A007656, for highest
atomic numbers (with no stable isotopes) and the values given are with
respect to Earth, as different planets have slightly different isotopic
ratios even in this solar system, and differ more widely from one star
system to another, and one galaxy to another. Taking round(mean(sum))
gives sequence: 1, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17,
18, 20, 21, 22, 23, 24, 25, 26, 27, 28, 30, 31, 32, 33, 34, 35, 37, ...
whose compliement (analogous to A070217) is 2, 29, 36, ...
%e A000001 a(1) = round(1.0080) = 1 = mean atomic weight of hydrogen
(protium + deuterium + tritium).
a(2) = round (1.0080+4.003) = round(5.011) = 5 (heium 4 and rarer
helium 3).
%Y A000001 Cf.A007656, A070217.
%O A000001 1
%K A000001 ,nonn,
%A A000001 Jonathan Vos Post (jvospost2 at yahoo.com
