On trust to the own imagination Without the knowledge accumulated in centuries, one fails even to make a step in physics. On the other hand, without the imagination, how can you perceive new things that are absolutely unknown yet. Therefore, … Continue reading
On simulation of status of a star In order to build an expensive detector for experiments at accelerators or in space, one should carefully calculate the response it gives to elementary particles trapped in it. Here, the nature has prepared … Continue reading
About that the laws of the mathematics allow to a person Mathematics rests more on the flight of thought, and therefore was developed faster than physics that was nourished by man-made experiments that require a lot of time and money. … Continue reading
On the possibility of losses due to negligent treatment People carry out experiments constantly, each day and not only in the science, just curious to see what would happen if … And later, when there is time, they attempt to … Continue reading
Going step by step, from ancient Greece to Europe via the east The Miletus school — Thales and his disciples Anaximander, Anaximenes — is considered to be the first at the beginning of the VI BC. It lasted for about … Continue reading
On the stunning results of elementary particle physics and cosmology Modern knowledge of the microcosm and the cosmos is still far from perfect. For example, we can not describe in detail the strong interactions of elementary particles, or explain the … Continue reading
Creating new technologies in the process of studying the universe In various fields of science, there are many examples where access to new technological levels occurred unintentionally, and began with the daily work and imagination of scientists. Exploration of new … Continue reading
Applying knowledge of the fundamental interactions to the universe At the beginning of the XX century, we were not aware of the existence of great number of galaxies yet, so the universe was identified with our galaxy, called the Milky … Continue reading
On the continuous movement of elementary particle fields in the universe When the quantum theory of the electromagnetic field has been extended to describe the strong and weak interactions, the fields of particles not yet known at that time were … Continue reading
Being born abundantly in each collision of collider beams Indeed, most of the observed matter consist of only three kinds of elementary particles: protons, neutrons and electrons. Apart from them, there are neutrinos and quanta of electromagnetic radiation — photons … Continue reading
About systematic study of the variety of particles, one after another In the second half of the last century it was created quite harmonious theoretical schemes that described interactions of the known elementary particles and predicted the existence of those … Continue reading
Predicting new particles and explaining the properties of those already known The basis of knowledge about the construction of the universe is the notion of elementary particles and their impact on surroundings. When a particle approaches close to another one, … Continue reading
Slowly but surely revealing the theoretically predicted particles… With their own hands physicists allow new species of particles that do not exist in substances to be born. The birth occurs when particle beams collide with either a target or each … Continue reading
Since ancient times, science was developing by alternating experimental and theoretical studies. Basing on experiments, scientists constructed a theory, and then if its predictions coincided with other experiments’ results, they accepted such a theory and adhered to it. For … Continue reading
Opening new technical opportunities a century after century… Of course, the understanding of the laws of the universe does not directly lead to significant improvements in people’s live. However, in the development of fundamental science a number of quite revolutionary … Continue reading
Shaping the laws of the universe from the properties of elementary particles… In fundamental physics, there are three closely related areas: physics of elementary particles, quantum field theory and physical cosmology. Their subjects of study are the space-time and elementary … Continue reading
