The heliocentric system of the world: from Aristarchus to Newton

The heliocentric system of the world: from Aristarchus to Newton

For the first time, the idea that the Earth revolves around the Sun arose in the minds of ancient Greek scientists. The founding father of heliocentrism is considered to be Aristarchus of Samos, who was born around 310 BC. How well he managed to work out his hypothesis is not known for certain, all information

Large Hadron Collider- LHC detectors in cern

Large Hadron Collider-LHC detectors

In giant detectors that are capable of reconstructing what happened during collisions, and all this in a very high collision rate environment, the events (an event is a collision with all of its resulting particles) are studied. They can be compared to extremely large three-dimensional digital cameras that can take 40 million “sequences” per second

LHC and other particle accelerator

LHC and other particle accelerators

The great challenges of today’s science require infrastructures and monstrous investments, among which are the Large Hadron Collider (LHC) – the particle accelerator that started on 10 Sept 2008, the most powerful in the world -, the Pierre Auger Observatory – the largest cosmic ray detector of the moment-, the Cassini Huygens probe – the

How Old is the Universe?

How Old is the Universe? (All Calculations so far)

A Bible-based assumption of a few thousand years old was made by Isaac Newton. Einstein believed in a World that was steady-state, ageless. Since then, somewhere in the centre, data obtained from the Universe places the probable response. First Ingredient: Quantum mechanics In the early 20th century, it was realized that the stability of atomic

Classical Physics vs Quantum Physics- The major Difference

What is the difference between classical physics and quantum physics? Physics that studies and explains the phenomena that occur in the domain of atoms, their nuclei, and elementary particles are called quantum; and the basic mathematical theory that explains the movements and relationships in this field is called quantum mechanics. However, it should not be

What is General theory of relativity? Equations & Examples

The General Theory of Relativity was published by Albert Einstein in 1915. The General Theory of Relativity is the accepted name published by Albert Einstein in 1915 for the theory of gravity. The force of gravity is a representation of the local geometry of space-time, according to the General Theory of Relativity. While the modern

Is there a more fundamental theory? More than just strings?

Is there a more fundamental theory? More than just strings?

If different string theories are related, then maybe they represent different limits of a bigger, more fundamental theory. To understand the presence of objects in string theory that are not strings, but higher-dimensional objects, or even points, it helps to know the formulation of Maxwell’s equations in the language of differential forms, because this is
