The point of view that weak interactions must have a second threshold below 300--600 GeV
is developed. Above this threshold new physics must come in. This new physics may be the …

This lecture is about my contribution to the proof of renormalizability of gauge theories. There
is of course no perfectly clear separation between my contributions and those of my co-…

It is noted that spontaneous symmetry treaking implies a finite cosmological term in the Einstein
equation for gravity. The present theories of weak and em interactions disagree violently …

In most calculations in high energy physics a certain amount of" t matrix manipulation is
unavoidable. The necessary equations were developed long ago by Fubini and Caianiello [1], …

The truly fundamental problems of physics can always be ex plained in simple terms without
the help of complicated equations or mathematical arguments. At least this was once told to …

The Higgs system is the great unknown of the standard model. Sofar, the Higgs itself has not
been seen, and experimentally, all we have is a questionable estimate of its mass. However…

In preparing this talk I have tried as much as possible to avoid the use of complicated
mathematical or graphical arguments. This type of considerations cannot be expected to be …
