Resonance in Physics: Explanation in Simple Language

Resonance

Why are the soldiers, who usually march in front step when crossing the bridge, are ordered to go “at ease”? Because marching across the bridge, they can destroy it. This happens due to an interesting physical phenomenon – resonance. However, the phenomenon of resonance is actively used not only in physics. For example, the term “public resonance” means the reaction of a large number of people to some event, political, economic, or social. But in our article, we will talk specifically about physical resonance, its significance in physics, causes, and the most striking examples from life.

Paramecium Caudatum – the Most Complex of the Simplest

Paramecium Caudatum

Life on our planet is characterized by an incredible variety of all kinds of living organisms, sometimes having an incredibly complex structure. All this diversity of life: from the simplest insects and plants to us, people (the most «complex organisms») consist of cells, these small bricks of living matter. If a human is the crown of biological evolution, then it will be very interesting to investigate its beginning: the simplest unicellular organisms which at the dawn of history became the founders of all life. The paramecium caudatum (along with amoeba) is one of the most famous simple unicellular creatures. What are the characteristics of the paramecium? What do paramecia eat? How do paramecia reproduce? Read on about all this below.

Friction Force in Physics: Definition, Formulas

Friction Force

The friction force arises from the contact of the surfaces of two physical bodies. The theory of friction worried the minds of mankind, since the earliest times. Ancient engineers: builders of the Egyptian pyramids, Stonehenge in England or mysterious stone idols on Easter Island, all of them (as well as their modern colleagues) were dealing with the problem of friction and how to minimize it. It is difficult to move heavy loads due to the friction force. Our distant ancestors invented such a useful invention as the wheel and many other important discoveries to solve this problem. In our article, we will look at the friction force in the physical aspect.

Tiger

Tiger

Although the lion is considered the king of animals, it is smaller than the tiger. Yes, the tiger is the biggest predator of the cat family. This “cat” has 3 meters in length with an average weight of 250-300 kg (550-660 pounds). The tiger name meaning came to us from the ancient Persian language, which means “sharp, fast”.

Amoeba

Amoeba

Amoeba is one of the most famous simple single-celled organisms and is an important object for the study of biologists. Understanding how the simplest unicellular organisms exist and function will help us to learn the very beginning of a long evolutionary path. What is the structure of the amoeba, its habitat? How does the amoeba eat? Read more about this in our article.
