signal using a cavity magnetron. The dimensions of the larger spherical cavity have to be calculated from the paper, (*))

59. Some Arguments for the Wave Equation in Quantum Theory 2 (pdf), (published in Open Journal of Mathematical Sciences (Volume 6)), (2022)

(This provides the theoretical justification for the idea that if an electromagnetic system is in thermal equilibrium and doesn't radiate

at infinity for all obsevers, then the charge and current obeys the relations given in (58). It seems clear that in the design of (58), the

larger spherical cavity should be in thermal equilibrium, and, as the charge is confined, shouldn't radiate at infinity, by Rutherford's

observation for atomic systems. The vanishing of the magnetic field in (58) can be checked by zero induction through a loop.The

signal can be detected by deflection of electrons; replacing the deflecting coils on a cathode ray tube with a wave guide.) I've added a

lemma at the end since the original publication.

we currently keep temperature and pressure in electrolyzers fixed. I've included the basic design and a further design more compatible

(I've included another design to generate the corresponding fundamental electromagnetic signal using an antenna. The three fundamental

modes and one reverse mode, as in the paper, could be simulated with four antennae or combined directly in one. The approximation

becomes better with the use of an n-gon and large n, instead of a pentagon, (**) The field created by the inducting loop can be cancelled

by winding the inner approximation like in one side of a transformer. The signal can be detected by electromagnetic induction, using a

circular loop for the antenna, attached to a radio reciver.)

72. Cosmati Pavements: The Art of Geometry, (published in Bridges Leeuwarden Proceedings (2008))

I've included a design to achieve igntion and control the firing rate wirelessly in a car or aircraft engine and a design to achieve controlled nuclear fusion. Both ideas rely

on the telecommunication designs of (58) and (63), the fusion idea is also related to the papers (60) and (61). These connections might lead to further integration between

these fields, the automotive, aviation and fusion industries.

2. The Fundamental Theorem of Calculus

My PhD adviser, at M.I.T, was Professor Byunghan Kim, who is an expert in the area of simple theories. A simple theory is a structure in which certain amalgamation

properties hold. You can find, here, some geometric pictures of 1-amalgamation and 3-amalgamation (1>2>3), used, particularly, in the second paper. My PhD thesis

was mainly concerned with developing properties of minimal structures in such theories. A minimal structure is, very roughly speaking, an abstract version of an algebraic

curve. Since then, I have been a research fellow at Edinburgh University, The University of Camerino and The University of Exeter, specialising in the geometry of

such curves.

(*) An attempt to recreate this design could be dangerous, due to the increase in charge density and current inside the spherical cavity.Note that this design is not the

same as putting a hollow metallic sphere inside a microwave oven; the radiation caused by a cavity magnetron would induce a current through the metal and cause

arcing, due to the changing magnetic field. The radiation generated by this design should have a zero magnetic field, though it can still accelerate charge due to the

electric field.

(**) This design is probably safer. It differs from a conventional transmitting antenna in that the current and charge density, at a given time, changes along different

portions of the loop.
