FRACTAL REACTOR: an ALTERNATIVE NUCLEAR FUSION SYSTEM BASED on NATURE's GEOMETRY Todd Lael Siler Psi-Phi Communications, LLC 4950 S
TR0700405 13th International Conference on Emerging Nuclear Energy Systems June 03-08, 2007, İstanbul, Türkiye FRACTAL REACTOR: AN ALTERNATIVE NUCLEAR FUSION SYSTEM BASED ON NATURE'S GEOMETRY Todd Lael Siler Psi-Phi Communications, LLC 4950 S. Yosemite Street, F2-325 Greenwood Village, Colorado 80111 USA E-mai 1: [email protected] ABSTRACTS The author presents his concept of the Fractal Reactor, which explores the possibility of building a plasma fusion power reactor based on the real geometry of nature [fractals], rather than the virtual geometry that Euclid postulated around 330 BC(1); nearly every architect of our plasma fusion devices has been influenced by his three-dimensional geometry. The idealized points, lines, planes, and spheres of this classical geometry continue to be used to represent the natural world and to describe the properties of all geometrical objects, even though they neither accurately nor fully convey nature's structures and processes. (2) The Fractal Reactor concept contrasts the current containment mechanisms of both magnetic and inertial containment systems for confining and heating plasmas. All of these systems are based on Euclidean geometry and use geometrical designs that, ultimately, are inconsistent with the Non-Euclidean geometry and irregular, fractal forms of nature (j). The author explores his premise that a controlled, thermonuclear fusion energy system might be more effective if it more closely embodies the physics of a star. This exploratory concept delves into Siler's hypothesis that nature's star "fractal reactors" are composed of fractal forms and dimensions that are statistically self-similar, (4) as shown in Figures 1 & 2. -

The intersection of each of these knots with the standard R3 ⊂ R4 is a nontrivial knot in R3. Thus a natural problem is to identify which knots can occur as such slices of knotted 2–spheres. Initially it seemed possible that every knot is such a slice knot and it wasn’t until the early 1960s that Murasugi [86] and Fox and Milnor [24, 25] succeeded at proving that some knots are not slice. Slice knots can be used to define an equivalence relation on the set of knots in S3: knots K and J are equivalent if K# − J is slice. With this equivalence the set of knots becomes a group, the concordance group of knots. Much progress has been made in studying slice knots and the concordance group, yet some of the most easily asked questions remain untouched. -

October 17, 2017 Abstract Let D be a knot diagram, and let D denote the set of diagrams that can be obtained from D by crossing exchanges. If D has n crossings, then D consists of 2n diagrams. A folklore argument shows that at least one of these 2n diagrams is unknot, from which it follows that every diagram has finite unknotting number. -
