The Geometric Algebra and the Numbers I
Path to the Infinities?
"Mathematics is the queen of sciences
and number theory is the queen of mathematics"
(Carl Friedrich Gauss)
The algebra started as a science of the counting and then it became general abstract area of the operations. The geometry evolved from the land-survey and it became the theoretical science of the spatial contexts. The calculation and measurement methods were more and more necessary because mathematics is becoming more and more abstract. So mathematics bifurcated into two areas and now we are making difference between pure and applied mathematics. No need to be explained why the number theory is the most important area in the theoretical and the applied mathematics. The science of numbers unbrokenly is the key area of mathematics Gauss citing the "queen of mathematics".1

1 I consider the counting as a special temporal operation and on the other hand the measurement as a spatial one. The geometric algebra is an encounter of algebra and geometry; it means an interconnection between the time and the space. It is no coincidence that the geometric algebra is currently the best way of describing space-time.

Thomas S. Kuhn and the Scientific Revolutions
Letter to BZ
Dear Z,
As I read, you deal with Kuhn's theory of paradigm as well. If you could see that my book is full of scribbled notes! (Incidentally, 1984 was 44Ft the price of this book. Incredible! This represents a 100-fold price increase in past 30 years!)
As much as I appreciate Thomas S. Kuhn's book on scientific revolutions, I do not agree with it in many respects, and even then I did this when I first read it. Maybe you are interested, so I summarize my feelings against his opinion.
(Additional contents:
– „Paradigma shift” and the law of “the transformation of quantity into quality”
– Kuhn and Karl Popper’s "falsificationism"
– Changes of information in a paradigma shift)

Einstein and the Dice
I would like to write about EPR experiment and Bell inequalities as well. Before writing this it is worthwhile to mention the much-quoted phrase of Einstein; “God does not play dice with the universe”1. Einstein thought that the world determined with causality and the outside world is independent of our cognition process. This belief of Einstein does not mean that our knowledge about the world would not be true only on a probability level. Reputedly Einstein said: “As far as the laws of mathematics refer to reality, they are not certain, and as far as they are certain, they do not refer to reality”. He believed that the probability character is not the attribute of the reality, but that of our knowledge about the reality.

Brief thoughts on John Gribbin's book1
John Gribbin’s book titled Computing with Quantum Cats is an eclectic opus. It mixes the history of science with biographical elements of some scientists and with presentation of IT development, supplemented by the theory and practice of quantum computers.
1. Schrödinger and the Kitten
Since there is a lot of hearsay about this Schrödinger’s thought experiment, it is worth reviewing it in more detail.
