Deriving E=mc^2 using 4-vectors and Special Relativity

In this video we work through a derivation of the formula for relativistic energy and show mathematically why it is a conserved and useful quantity. The derivation builds up from a familiarity with 4-vectors, the inner product in Minkowski space, proper time and the Lorentz factor. We also show how E=mc^2 is a special case of this energy in the rest frame of the particle with mass m.
For a full in depth series on special relativity I highly recommend Eigenchris’s channel: ruclips.net/user/eigenchris
Of course, if there’s something you’d like me to cover feel free to ask in the comments section

Using a capacitor as a simple field, this field derives the energy density of the electric field using the energy in a capacitor, the electric field of a capacitor and the definition of capacitance. The equation is then generalised to all fields.

Gliese 436b is a distant exoplanet that is believed to be covered in ice despite having a temperature over 400°C. How is this possible? All is explained in this short video. Specifically, phase/state of matter depends not only on temperature but on pressure as well. #veritasiumcontest #exoplanets #physics Sources Wikipedia - Gliese 436 b, Triple Point Image/Video Sources in order of appearance ...

The Photoelectric Effect in One Minute

Просмотров 2,7 тыс.3 года назад

The Photoelectric effect as explained by Einstein represents the birth of quantum physics and the concept of a wave-particle duality. In this video, it is briefly introduced as evidence against the wave model of light. Instead, the photoelectric effect supports the particulate model of light (as packets called photons). These photons (as evidenced by the photoelectric effect) have energy propor...
