Introduction to general relativity – Astrophysical applications

Models based on general relativity play an important role in astrophysics, and the success of these models is further testament to the theory’s validity. Gravitational lensing Since light is deflected in a gravitational field, it is possible for the light of a distant object to reach an observer along two or more paths. For instance, [...]

Cryogenics

Inversion temperature – Introduction

inversion temperature in thermodynamics and cryogenics is the critical temperature below which a non-ideal gas (all gases in reality) that is expanded at constant enthalpy will experience a temperature decrease, and above which will experience a temperature increase. This temperature change is known as the Joule-Thomson effect, and is exploited in the liquefaction of gases. [...]

Celestial Mechanics

Classical mechanics – Branches

Classical mechanics was traditionally divided into three main branches: * Statics, the study of equilibrium and its relation to forces * Dynamics, the study of motion and its relation to forces * Kinematics, dealing with the implications of observed motions without regard for circumstances causing them Another division is based on the choice of mathematical [...]

Natural Science

Natural science – History

In ancient and medieval times, the objective study of nature was known as natural philosophy. In late medieval and early modern times, a philosophical interpretation of nature was gradually replaced by a scientific approach using inductive methodology. The works of Ibn al-Haytham and Sir Francis Bacon popularized this approach, thereby helping to forge the scientific [...]

Astrophysics

Astrophysics – Introduction

Astrophysics (Greek: ”Astro ”- meaning “star”, and Greek: ”physis ”– ”φύσις ” – meaning “nature”) is the branch of astronomy that deals with the physics of the universe, including the physical properties (luminosity, density, temperature, and chemical composition) of celestial objects such as galaxies, stars, planets, exoplanets, and the interstellar medium, as well as their [...]

Biophysics

Biophysics – Introduction

Biophysics is an interdisciplinary science that uses the methods of physics and physical chemistry to study biological systems. Studies included under the branches of biophysics span all levels of biological organization, from the molecular scale to whole organisms and ecosystems. Biophysical research shares significant overlap with biochemistry, nanotechnology, bioengineering, agrophysics and systems biology. Molecular biophysics [...]

Natural science – Branches of natural science

Astronomy This discipline is the science of celestial objects and phenomena that originate outside the Earth’s atmosphere. It is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe. Astronomy includes the examination, study and modeling of stars, planets, comets, galaxies and the [...]

Wonders and milestones of Science for civilization

By: Man SinghRight from ancient time science has revolutionized a wheel of progress made so far. Historical contribution of science for society was initiated by Alexander Grahm Bell whose mom and students whom he married were deaf, on March 10, 1876, at small laboratory at Boston, USA, established a communication from one room to another.

Critics to Shrodinger´cat

This is a straightforward critics to Copenhagen School about the experiment of thought from Erwin Shrodinger. It Is another way to view the nature itself without going to the extreme idealism about tha facts of Nature.
