Cyclic Definition and 309 Threads

How does one find the most probable central location of something/someone when four points of their earlier location have been recorded and drafted? For example, if one is given points A, B, D, and C, how would they find the central location? This method must use cyclic quadrilaterals, and four...

I'm trying to do this ferrocene lab, and we did cyclic voltammetry on our purified product and I calculated these results: E_1/2= 664.6 mV I_pc/I_pa=-.6221 Delta Ep=29.2 mV Can anyone tell me what these numbers mean? I don't really understand what voltammetry tells you about your...

If I have an abelian group A that is the direct sum of cyclic groups, say A=[tex]C_5 \oplus C_35[\tex], would I be right in saying the annihilator of A (viewed as a Z-module) is generated by (5,35)? If not, how do I find it?

Here's an interesting question which is related to proofs, one of the hardest chapters of math: If a circle can be drawn to pass through the 4 vertices of a Quadrilateral, we call this a "cyclic quadrilateral". What special properties do you think a cyclic quadrilateral has that wouldn't be...

Here is a new paper by Niel Turok and Paul J Steinhardt. http://uk.arxiv.org/PS_cache/hep-th/pdf/0403/0403020.pdf The initial reading makes one ask a simple question, if I was to be at a far away location, say at the QSO of farthest detected Galaxy, and I looked back to the location of...

Hi everybody! Question #1 What is the definition of a Klein group? The K_4 group has a table that looks like this: \begin{array}{c|cccc} *&e&a&b&c \\\hline e&e&a&b&c\\ a&a&e&c&b\\ b&b&c&e&a\\ c&c&b&a&e \end{array} What is the strict definition of a Klein group? That every...

The cyclic model was introduced in this paper: "A cyclic model of the universe" http://arxiv.org/abs/hep-th/0111030 and is a idea of Steinhardt and Turok. (Some might some day recognize the great quantities of ideas that Steinhardt has introduced in the last 30 years). The model proposes an...

A cyclic group of order 15 has an element x such that the set {x^3, x^5, x^9} has exactly two elements. The number of elements in the set {x^(13n) : n is a positive integer} is : 3. WHy is the answer 3? Thanks!

1/7 = .142857... (repeated) 2/7 = .285714... 3/7 = .428571... 4/7 = .571428... 5/7 = .714285... 6/7 = .857142... So, you get all n/7 from the same 'cycle' of 6 digits. Let's call 7 a 'cyclic' integer. The next cyclic integers are 17, 19, 23,... They are all prime. But 11, 13, or 37 are...
