Why is there something and not just nothing? This is the ultimate question of all questions.

The question of where the first life came from is one of the seven Welträtsel described by Emil du Bois-Reymond in 1880. Werner Ahrendt substantiates his assumption that the first forms of life originated on the seabed.

All living organisms on Earth use the same genetic code to translate genetic information into proteins. Werner Ahrendt presents a hypothesis as to how this code may have evolved over the course of natural history.

Near Carnac, a village on the French Atlantic coast, there is a striking collection of upright stones arranged in parallel rows. Several groups of these stone rows can be distinguished. Each group consists of several parallel rows of stones, each stretching for several hundred meters. The stones are between 0.5 and

"A somewhat rash philosopher, I think Hamlet, Prince of Denmark, said: There are a lot of things in heaven and on earth of which there is nothing in our Compendiis. If the simple-minded man, who, as is well known, was not in his right mind, was jibing at our Compendia of Physics, one can confidently answer him: Well, but then again, there are a lot of things in our Compendiis of which there is nothing in heaven or on earth."

Georg Christoph Lichtenberg

How what we call consciousness arises in the brain is undoubtedly one of the world's great unsolved mysteries. Emil du Bois-Reymond posed this question in his famous lecture, "The Seven Mysteries of the World," given at the Berlin Academy of Sciences in 1880: "Where does conscious sensation come from in the unconscious nerves?"

In the temperate climates of the northern and southern hemispheres, respiratory infections have always occurred preferentially in the winter months. Even ancient writers wrote about it. The seasonal fluctuations in the spread dynamics of the SARS-CoV-2 coronavirus were also very pronounced during the coronavirus pandemic. However, the reasons for this seasonal variation are still not fully understood.

On closer inspection, however, it is not the case that respiratory infections only

Problems can never be solved with the same mindset,
that created them.

Albert Einstein (1879 - 1955)

Over the past 500 years, the science of physics has limited itself to recording what happens in nature using measuring instruments and describing the relationships found using mathematical formulae. Therefore today's physics cannot explain the nature of things nor the genesis of physical laws. Both issues are considered

Human beings are capable of greater intellectual achievements than any other living creature on earth. How did this happen? The answer may shed some dark light on our ancestors.

What is "time"? This question not only moved the church father Augustine, but is still a fundamental question for our understanding of the world today.

The properties of elementary particles show regular patterns, especially in their electrical charges. How can these regularities be explained?

All elementary particles have a property called spin, which is interpreted as the intrinsic angular momentum of the particle. In classical mechanics, each angular momentum is associated with rotational energy. Is rotational energy also associated with the spin of elementary particles? If so, how big is it?

In the common narrative of the history of science, one finds the story that classical mechanics was replaced by Einstein's theory of relativity and is contained in the theory of relativity as a special case for small velocities. On closer inspection, however, this narrative is not quite right.

The principle of least action, also known as Hamilton's principle, is a fundamental principle of theoretical physics from which the laws of motion in many areas of physics can be derived. However, our current knowledge gives no indication as to why this principle is universally valid.
