***************************
The AstroNuclPhysics system presents a number of interconnected scientific treatises in electronic form in the fields of nuclear and radiation physics, including some applications, the theory of relativity. , astrophysics, cosmology and scientific- philosophical considerations. Supplemented by passages from the field of culture, sacred music and marginally also a few observations and social views. Structure of web-pages: Clicking on one of the four thematic frames will open the relevant page, on which the content is listed in the narrower left frame. (list of materials) of a specific heading. We start individual materials by clicking on the appropriate entries in the left bar - the selected topic will open and be displayed in a wide main frame. If we want to go to another basic area, we click on " cTitle page ", which is this page, on which we select a new basic area by selecting one of the thematic frames again. Note: When navigating from the introductory page, an introductory text characterizing the content of the area and provided with the author's personal notes will be displayed together with the list on the left. To display the text of materials in the entire screen window, use the menu in the table below: í |

When opening the frames with thematic areas mentioned above,
the content is permanently displayed in the left bar and the
actual materials are displayed in the window on the right - this
is clear in terms of switching between individual titles.
However, to study a specific selected title, it may be more
advantageous to display it in the

Excuse for errors and distortions:
The AstroNuklPhysics system is continuously supplemented and
modified. I therefore apologize for some errors and
inconsistencies that arise during the creation and editing, as
well as for incompleteness - other topics will be added
gradually, some passwords that are still inactive will be
operational. When transforming texts from other editors,
mathematical formulas were distorted and destroyed in some places
- it will be gradually corrected. ...Thank you for
understanding...
Apology to fellow
specialists
If these materials are opened by a fellow physicist
professionally working in nuclear physics and radiation
applications (research, industry, medicine), theoretical physics
or astrophysics and cosmology, I must apologize if he finds
nothing new for himself and interesting. However, as I can judge
from my own experience, reading something I already know from
elsewhere can be a pleasure - especially when it is given from a different
perspective .
In specific specialized materials, I also
try to overlap some of the neighboring
disciplines (sometimes even more distant ones) and to put some
special knowledge into the broader context of science..
So, for example, when reading X-ray diagnostics, Radiotherapy,
Nuclear Medicine, a doctor can learn something interesting about
nuclear physics, elementary particles and possibly about related
processes in space. Conversely, in the chapters Nuclear Physics,
Ionizing Radiation, Radiation Detection, a physicist can read
about the processes in cells, the biological effects of
radiation, the diagnosis and therapy of certain diseases ...
The Joy of Knowledge
Scientific knowledge of new, often previously unsuspected
phenomena and the beauty of the architecture of their
interrelationships, expressed in the laws of nature, gives the
thoughtful person the ultimate joy of knowing
"how our world works", what the essence of
things and events is. This inner feeling is spiritual in
nature, not unlike "religious ecstasy" or samadhi in
meditation. This leads us to a deep respect for
the grandeur of the hidden order and the "reason" that
is immanently embodied in being. Through internally understood
scientific knowledge, we can attain liberation
from the shackles of pettiness and selfishness, attaining the
spiritualization of our understanding of the world and refinement.
mutual relations with each other and with living and inanimate
nature.
However, there is still a lot we do not yet know
and may not even know. More adventures of knowledge
await us!
The basic motive for the creation of these
pages is the desire for knowledge - knowledge of
the often hidden, innermost and most basic mechanisms and laws
that govern our world. And a friendly sharing of inspiration and
joy from discovering the beauties and secrets of nature
and the universe with other colleagues and "soul
mates" on this journey ...

welcome comments, opinions and personal knowledge of readers

The Path of
Knowledge
When a person embarks on a path of knowledge in his youth, he does
not know and understand almost anything. He has only an open head
and a desire in his heart to know and understand everything
. Then all his life he slowly
walks along the shore of the ocean of the unknown and modestly
collects shards of knowledge. At the end of his journey , however, he often has to
admit that he does not know much
more than at the beginning. He knew and understood a lot of
partial knowledge of the functioning of the world - current
knowledge fills us with joy! However, the innermost essence of
all phenomena and events, the root cause of everything ,
is perhaps as distant to us as at the beginning ...? !. .
Personal limitations ...
One would like to know so
much - to explore, to study, to understand, to pass on - but
there is not enough time and energy
Today I understand many
things that I did not understand before; but again I cease to
understand other things that I previously took for granted
For example: quantum physics (the essence of
stochastic behavior of interactions?), electrodynamics (origin of
electric forces, magnetism - what structure in an electron
excites a magnetic field by its motion? field is an electron ??)
.. and many more ... The question is whether it is a gradual
"fooling around" with increasing age, or the fact that
in youth one tried to quickly grasp and apply existing knowledge
without thinking so much about the inner nature ..? ..
My view on the relationship between science
and the development of society: The utmost modesty in
personal life and maximum effort in scientific cognition
, along with the cultivation of culture, art, a sense of goodness
and beauty. Only these values ??can be passed on to future
generations; not transient material "goods." Keep
your heart simple and mature to the wisdom of the spirit
.
It is a great pity that we have only one life, which is
too short - just a small moment in the evolution
of the Universe. Lots of amazing possibilities, different paths
of life, knowledge, creation, beauty, is thus out of reach for
us. Whatever path we choose (or this path is chosen for us by
circumstances), it will be just one of many other possible ones,
on which many unfulfilled ...
I did not embark on the path of "collecting"
scientific titles and ranks. Due to my personal modesty and
unpretentiousness, I did not even aspire to public recognition,
leadership or social status. I have no need to command or exalt
anyone, nor to listen headlong to anyone - I only recognize the
power of objective arguments ... My only
"ambition" in this regard is to know and understand how
our world works? From physical fields and elementary
particles, through atoms, molecules, matter, to stars, galaxies
and the entire Universe. And also life-
biological systems. Although this is not my professional
"parquet", I consider molecular biochemistry and
genetics, subcellular and cell biology in particular to be the
most interesting parts of science, together with "its"
nuclear physics, astrophysics and cosmology ... And share
, complement and refine this knowledge with other colleagues and
candidates - regardless of their formal education, titles, ranks,
social status (I do not need much inflated
"elites" ...) . Even discussions
with employees from other fields, with lay people or students who
are just getting acquainted with the given area, can enrich our
professional conception with new perspectives.
Physicist - " sunken
patriot "
With this comparison, it is possible,
with a bit of exaggeration, to express my personal position -
symbolically and literally. In terms of social attitudes,
patriotism is really close to me in the spirit of our National
Revival (" Czechoslovakia - our homeland
": Czechness + Slavism, with respect and friendship to all
nations - internationalism ). And as a physicist, I move
in seclusion , in an environment far from large
research centers, financial resources and subsidies. Internally
deeply passionate about his field, but mostly without the
possibility of applying and enforcing his ideas, experiences and
approaches. This is how it developed in life (a few notes on this
are in the passages " About the author ",
" Nuclear
and radiation physics - author's notes
" and "Theory of relativity, astrophysics - author's notes "); in general, it is largely due to the modest
and introverted nature ...
Note on the thematic area Society - Philosophy - opinions -
attitudes:
This thematic area is included in thespecialized
pages of AstroNuklFyzika only marginally
and expresses my personal opinions and attitudes, based on life
experience. I always strive for an objective view
and evaluation, without any personal interests and ambitions,
regardless of the current ruling ideology and trends
imposed by the mass media. Therefore, perhaps this view may seem
nonconforming and controversial to some. Nevertheless, I
will be happy if readers think about these topics as well. If any
of you, dear readers, have a different opinion - which I
respect ! - and my
attitudes make him angry and annoyed, believe me, it is a misunderstanding
: as people of good will *) we are " on the same
boat " and in my opinions I speak for you, only
maybe from a different point of view .
*) I do not assume that these pages will be read
by people of will other than good ...
I will only side
with everything that serves the benefit of good and
decent people , their mutual equality, freedom,
tolerance, cooperation, justice, equal opportunities for
education and all-round development. I then denounce the opposite
phenomena and trends and call them by their real names
. I believe in the prevailing human wisdom ,
goodness and nobility that needs to be cultivated and protected
from willpowerselfish, proud and arbitrary people. This
should be the main task of the left.
If some of the
readers do not know that this is a well-meaning view from another
angle and do not want to think about it soberly and without
emotion, then I would like to ask that instead of anger and
negative attitude, they ignore this whole topic
and not connect it with others. professional topics on this site.
I always emphasize what unites people and not
what divides them! I ask for kind tolerance for
different opinions and attitudes, as manifestations of the diversity
and diversity of our beautiful world
.
