A method is presented for obtaining irrational speeds of growth of configurations in generalized Pascal triangles and one-dimensional cellular automata. ... This method does not use diagonalization or simulation of Turing machines but uses a number-theoretic idea. ... We shall use this idea to construct generalized Pascal triangles (and, hence, implicitly also one-dimensional cellular automata) with this speed of configuration growth also for some noninteger b and q ...doi:10.1016/0304-3975(93)90029-s fatcat:b5krc7w47bcqbeav6j4cvyvbpa

Using this idea, generalized Pascal triangles and also one-dimensional cellu- lar automata with the above speed of configuration growth can be constructed for some noninteger p and q. ...
Speeds of configuration growth in GPT -Definition. Generalized Pascal triangles can be considered as computations of one-dimensional cellular automata from finite initial configurations. ... In the next section it is shown how to meet this condition in a nontrivial way. 5. Irrational speeds of configuration growth. ...doi:10.4064/-28-1-125-134 fatcat:n6r3c6km4nhe7bjwrvedz4aioy
The predominance of Fibonacci order in botany is related to this continuity: during the ontogeny, because of the continuous decrease in G, only this branch is followed. ... The dynamic is controlled by only one parameter, G, equivalent to Richards' plastochrone ratio (1951) , which characterizes growth. ... The programme was written in Think Pascal (18 pages, mostly used for the presentation). ...doi:10.1006/jtbi.1996.0024 fatcat:5jy5dths2vd3xlvrvfonqik5ki
The present chapter introduces the fields of mathematics that will be considered "elementary" in this book. ... They have all been considered "elementary" at some stage in the history of mathematics education, and they are all still taught at school level in some places today. ... For the germ of the idea that led to this book, credit should go to Vagn Lundsgaard Hansen and Jeremy Gray, who commissioned my article on Klein, and later suggested that I write a book of a similar kind ...doi:10.5281/zenodo.6080488 fatcat:duf7ea2kpbemvj4yfg4ewizlw4
Making up Numbers
In the seveteenth century Blaise Pascal used induction explicitly when justifying the properties of his well-known Pascal triangle (see Figure 30 , page 122). ... Dedekind's elegant paper (  ) is entitled Stetigkeit und Irrationale Zahlen (Continuity and irrational numbers). ... We might counter their concerns with Hadamard's confident assertion (quoted in Section 1) that 'essential progress in mathematics' results from including notions which, for earlier generations, 'were " ...doi:10.11647/obp.0236.06 fatcat:v22whoog6bgzjfevq2dd74g35a
This workshop brought together people working on the dynamics of various flows on moduli spaces, in particular the action of SL 2 (R) on flat surfaces. ... The new results presented covered properties of interval exchange transformations, Lyapunov spectrum of this flow and the geometry of Teichmüller space. ... In joint work with Pascal Hubert and Howard Masur  , we show that (i) H. Dim DIV(P λ ) = 1 2 if λ is irrational, and is otherwise zero; (ii) H. ...doi:10.4171/owr/2011/25 fatcat:gkhpmswwgfb7pnuvzi5yy2vqku
