Emotions of senior physicist, which are caused by his incompetence in software Modern physics, theoretical and experimental, increasingly relies on modeling and data processing using powerful computer systems. If your research supervisor does not understand things of this kind, it’s … Continue reading
Warning of a danger of losing mind… One can briefly state just facts, but not their relationship and relative importance. Therefore, the results of scientific research could not be reduced simply to tables and charts, and are usually expounded in … Continue reading
About love to the computer The personal computer has imposed a strong imprint on the views of young people on the physics and on methods of their work in science. Most of them do not remember themselves without a laptop. … 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
About disorderly changing information in the memory It is known that man has short-term and long-term memories, just like there are RAM memory and the ‘disk’ installed in your machine. In the long-term memory, recollections can be stored for a … Continue reading
On some steadfastness If it is necessary to carry out several tasks, it is possible to make them either in parallel or the first one, then another. The former version is merrier — monotony lulls to sleep. However, the latter … Continue reading
About a secret Hand in hand with the new, there is routine in physics. Imagine if you obtained a task to carry out some work, but every day could not start — something does not give you to make the … Continue reading
On the capacity of one word… It’s well known that the English language is as important for physics as Latin for medicine. When you are writing a letter or an article in English, to accurately convey your thoughts to a … Continue reading
About a blizzard of unnecessary words… Here is an example of a scientific meeting held in our institute. First, the convener had said everyone should make a computer account at a new experiment, without saying why. The first report was … Continue reading
Experiences at fault All make mistakes sometimes, but actually nobody is bold enough to admit his fault even to himself. Fundamental physics, like any other science, is in the essence the road of trials and errors. There is often necessary … Continue reading
On sharp pricks When using simple measuring instruments such as a micrometer or ammeter, they hope for the accuracy of measurement, indicated on the tool, obtained as a result of its calibration. Detectors, used at the Large Hadron Collider, are … Continue reading
How electrons began to remain in orbits In the early hot universe, free electrons were being captured by protons, forming hydrogen atoms. The photons, emitted in this process called recombination, took away the difference between the summary mass of free … Continue reading
Increasing the visible size keeping the same amount of light emitted When we look at a distant source of light that spreads in all directions, we see only a portion of the photons emitted by it. As the distance from … Continue reading
About how the pressure of the Fermi gas restrains from compression There are the reactions of nuclear fusion in the core of a star — of the formation of more heavy atomic nuclei, which is accompanied by the release of … Continue reading
Conversion of the protons of star into neutrons with the emission of neutrinos So-called supernova explosion occurs as a result of gravitational collapse of a star, completing its life cycle, if its weight exceeds a few solar masses (the Chandrasekhar … Continue reading
On searches for antimatter in space… The observed domination of protons, neutrons and electrons over their antiparticles means that our universe has got the so called baryon quantum number. This is composed of baryon numbers of each of nucleons. It … Continue reading
Passage of dark matter particles through substances without interacting… The dark matter makes up more than 80% of the matter of the universe. This does not almost radiate electromagnetic waves and manifests itself basically by its gravitational interaction. It may … Continue reading
How the decay of particles overtook that of antiparticles… It is observed that the number of baryons in the universe (protons and neutrons) exceeds the number of antibaryons at least ten thousand times. Such an asymmetry could arise in the … Continue reading
Hesitating between continuing the expansion and the transition to contraction The curvature of space of the universe is one of the factors that determine the law of its expansion. Data of observations do not contradict the fact that three-dimensional space … Continue reading
