  2. Clarke Studies - Wikipedia

    en.wikipedia.org/wiki/Clarke_Studies

    The second volume, published in 1912 as Clarke's Technical Studies for Cornet, includes 190 exercises divided into ten studies with notes from the author suggesting how to practice them. Each of the ten studies concludes with an exercise serving as an étude , except for the ninth study, which lacks an exercise labeled as such, and the tenth ...

    en.wikipedia.org/wiki/Clarke's_three_laws

    The second law is offered as a simple observation in the same essay but its status as Clarke's second law was conferred by others. It was initially a derivative of the first law and formally became Clarke's second law where the author proposed the third law in the 1973 revision of Profiles of the Future, which included an acknowledgement.

    In particle physics, the doublet–triplet (splitting) problem is a problem of some Grand Unified Theories, such as SU(5), SO(10), and .Grand unified theories predict Higgs bosons (doublets of ()) arise from representations of the unified group that contain other states, in particular, states that are triplets of color.

    Mary Elizabeth Tyler (July 10, 1881 – September 10, 1924) was an Atlanta public-relations professional who, along with Edward Young Clarke, founded the Southern Publicity Association. Their organization helped to turn the initially anemic second Ku Klux Klan into a mass-membership

  7. Doublet state - Wikipedia

    en.wikipedia.org/wiki/Doublet_state

    In quantum mechanics, a doublet is a composite quantum state of a system with an effective spin of 1/2, such that there are two allowed values of the spin component, −1/2 and +1/2. Quantum systems with two possible states are sometimes called two-level systems .

  8. Multiplicity (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Multiplicity_(chemistry)

    The total angular momentum quantum number J can vary from L+S = 2 to L–S = 0 in integer steps, so that J = 2, 1 or 0. [1] [2] However the multiplicity equals the number of spin orientations only if S ≤ L. When S > L there are only 2L+1 orientations of total angular momentum possible, ranging from S+L to S-L. [2] [3] The ground state of the ...

    The first was that he and Watson never had before counted the 20 amino acids or the possible 20 nucleotide triplets [19] (although Gamow was subsequently proven to be correct and his model was the first prediction of the genetic code [17] [23]). The other issue was that RNA and protein synthesis appeared to exclusively take place in the ...
