Did you know ? The rules that mathematical logic derives from the research of thinking are analogous to the rules of mathematical, especially algebraic, operations. The task of mathematical logic is actually the same as the task of traditional logic, namely to develop procedures by means of which we could verify the correctness of our logical conclusions, or in other words, by means of which we could distinguish valid conclusions from invalid ones.

Did you know ? Ludolf's number, colloquially (pi) or, exceptionally, Archimedes' constant is the ratio of the circumference of a circle to its diameter. Whether the circle is small or large, ( pi ) is still the same, it is a mathematical constant. This constant is commonly used not only in mathematics but also in physics, engineering and other sciences. Ludolf's number is an irrational, transcendent number whose first three digits are 3.14.

Did you know ? Quantum mechanics is a theory that deals with the behavior of subatomic particles such as atoms and their constituents. Quantum mechanics describes how particles behave at microscopic levels, such as their motion, spin, charge, energy, and various properties. This theory is important for understanding many physical and chemical phenomena, such as the electronic structure of atoms, spectroscopy, electron microscopes, nuclear reactions, and many others. Quantum mechanics is also important in many modern technologies, such as quantum computers and cryptography.
