Example text

Now we recapitulate the well-known Kepler’s third law, which says that the squares of the periods of revolution around the Sun are proportional to the cubes of the distances. 5) where R is the distance from the planet to the Sun, and T is the period. A planet moves around the Sun in a circle or an ellipse in one topological dimension, D = 1, so the exponent should be 1/2 or a multiple of 1/2. 6) where D is the dimension of the organism’s construction, for example D = 2 for a leaf [11], D = 3 for an animal [12], and D = 4 for a human brain [13].

Thus, at the quantum scale, Einstein’s space–time must become discrete in the sense of quantum mechanics, resembling a stormy ocean due to quantum fluctuation or the equation would be extremely limited. The problem in Einstein’s field equation can be eliminated using El Naschie’s E-infinity theory [22], which regards discontinuities of space and time in a transfinite way. Introducing a new Cantorian space–time, El Naschie admitted formally an infinite-dimensional ‘real’ space–time, which is hierarchical in a strict mathematical way.

19) Here κ is twice the mean curvature of the interface, κ = 1/R1 + 1/R2, with R1 and R2 the principal radii of curvature, ε is the dielectric constant of the fluid, and is the dielectric constant of air. 20) In addition to conducting bodies, there are also dielectrics. In dielectrics, the charges are not completely free to move, but the positive and negative charges that compose the body may be displaced in relation to one another when a field is applied. The body is said to be polarised. The polarisation is given in terms of a dipole moment per unit volume P, called the polarisation vector.
