By Lucian Pasieka The air we breathe is a very important natural gas mixture without which we could not live. Are we aware that we consume an almost infinite number of gas molecules throughout our lives? From the air, which contains approximately 78% N2, 21% O2, 0.94% Ar as well as 0.04 CO2, our body…

By Lucian Pasieka There are many things in everyday life that we “measure”. For example, we hold a ruler to an object and say: “This is about 20 cm long,” i.e., we compare it to a reference. Measuring is considered one of the foundations of modern civilisation as it is needed in many domains. Often,…

By Lucian Pasieka So-called renewable energy (electricity from wind, water, sun) enables us to follow a path that is more closely aligned with natural circulation processes. During the generation of electricity from solar energy, i.e. photovoltaics, hydropower and wind, there is the additional desire and need to store surplus energy. So, how can we store…

When these objects are used, a relative movement between at least two components is usually required, e.g., when closing a classical espresso machine with a rotary movement or when opening and closing a window. All these movements…

By Lucian Pasieka In nature, there are materials that consist of a variety of individual structures (molecular chains), which only demonstrate their desired characteristics as coupled systems. An example of this kind in the field of mechanics is the interplay between elastic and damping components. In the human body, elasticity and damping are coupled in…
