    Nucleotide Frequencies in Human Genome and Fibonacci Numbers

    This work presents a mathematical model that establishes an interesting connection between nucleotide frequencies in human single-stranded DNA and the famous Fibonacci's numbers. The model relies on two assumptions. First, Chargaff's second parity rule should be valid, and, second, the nucleotide frequencies should approach limit values when the number of bases is sufficiently large. Under these two hypotheses, it is possible to predict the human nucleotide frequencies with accuracy. It is noteworthy, that the predicted values are solutions of an optimization problem, which is commonplace in many nature's phenomena.Comment: 12 pages, 2 figure

    Puritanism

    Puritanism was a strain of English Protestantism that emerged after the re-establishment of the Protestant Church of England by Elizabeth I in 1559. Puritanism was not a coherent set of ideas, but rather a form of intense piety that led many to criticise the Church of England for not being as Reformed as Calvinist Churches on the continent. As such, Puritans and Puritanism changed in light of changing religious and political dynamics in Early Modern England, becoming an increasingly political force under Charles I and leading to the English Civil Wars. Different Puritans promoted different models of a spiritual society in order to realise their ideals including conforming to the established Church; Presbyterianism; or Separation and exile to America. What was constant, however, was a commitment to personal spiritual growth that produced an influential genre of writing on practical divinity
