Symmetry – Magnetic Vs Electric Field

35 Views0 Comments

In this video, the difference of behaviour towards symmetries between electric and magnetic fields is explained. This leads to practical simplifications when dealing with highly symmetric charge distributions or curre...

Bolzano Weierstrass theorem – Rising sun proof

93 Views0 Comments

Bolzano-Weierstrass is a fundamental theorem in analysis, stating that we can extract a convergent subsequence from any bounded sequence. It is proven in this lesson using a sun shining in the horizon. Speaker: El Ma...

In this video, we discover dynamics in distributed hash tables, in particular, insertion and removing of a node. Speaker: Anne-Marie KERMARREC.

Electric field of an infinite plane with Gauss theorem

128 Views0 Comments

With few calculations, we can compute the electric field thanks to symmetries and Gauss law, this is illustrated here where we avoid the calculation of the electric field with infinite integrals. Speaker: El Mahdi EL...

Practice of Gauss flux theorem

38 Views0 Comments

Gauss theorem in electrostatics provides a direct link between the charge distribution inside a closed surface and the flux of the electric field across it. From a practical point of view, it offers an idirect but eas...

Symmetry Principle in Physics
