Physics in General
Physics is a natural science that studies fundamental phenomena in nature.
In order to explain its properties and behavior on the basis of quantitative models and laws, physics deals in particular with matter and energy and their interactions in space and time.
Explaining here means classifying, comparing, assigning more general phenomena or inferring from general laws of nature.
This often requires the formation of new, suitable terms, sometimes also those that are no longer directly accessible.
Physics cannot provide explanations in the philosophical sense of “why” nature behaves in this way.
Instead, it deals with the “how”. For example, she cannot explain why crowds attract one another. This behavior can only be described with different models.
Newton did this by assuming that there is an attraction between bodies. Einstein had a completely different idea, who explained gravity by saying that matter bends space-time.
The way physics works consists of a combination of experimental methods and theoretical modeling like in electromagnetism.
Physical theories prove themselves in the application to systems of nature, in that they allow predictions about later states with knowledge of their initial states.
Advances in knowledge result from the interplay of observation or experiment with theory.
A new or further developed theory can explain known results better or at all for the first time and can also stimulate new experiments and observations,
the results of which then confirm or contradict the theory. Unexpected results of observations or experiments give rise to the development of theories in various forms,
from gradual improvement to the complete abandonment of a theory that has been accepted for a long time.
Findings and models of physics are used intensively in chemistry, geology, biology, medicine and engineering.
About a PhD
The doctorate (Latin promotio “promotion”) is the award of the academic degree of a doctor or an honorary doctor in a certain subject and in the form of a doctoral certificate.
It is valid as proof of the ability to do particularly in-depth scientific work and is based on an independently written scientific work, the dissertation and an oral examination (Rigorosum, disputation or colloquium).
Universities and universities of equal status as well as German universities of applied sciences in Hesse that are strong in research have the right to award doctorates.
Individuals who are aiming for a doctorate and whose intention and suitability have been confirmed by an institution entitled to do a doctorate are recognized as doctoral students, doctoral students, doctoral students, doctoral students (Switzerland, Austria), doctoral students (Switzerland, Liechtenstein) or English called PhD students.
The corresponding verb doctorate is used both transitive (example: “you have received a doctorate”) and intransitive (example: “I have a doctorate”).
In order to be admitted to the doctorate, a first university degree must be proven; only in medicine can a dissertation be started before the end of the course.
As a rule, this is the master’s, magisterial, diploma or state examination. Particularly qualified graduates of a bachelor’s degree or a diploma degree from a university of applied sciences can also be admitted to doctoral studies under certain conditions.
