The Stefan-Boltzmann law states that the total thermal radiation power emitted by an object is directly proportional to the fourth power of its absolute temperature. It is the fundamental principle used to calculate the heat radiated by stars, fires, and other everyday objects.

Coulomb's Law is a fundamental principle in physics that describes the electrostatic force of attraction or repulsion between two charged particles. It states that the force between two point charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them.

Gauss's Law is a fundamental principle in electromagnetism that relates the distribution of electric charge to the resulting electric field. It states that the total electric flux passing through any closed, hypothetical surface (called a Gaussian surface) is exactly equal to the net charge enclosed inside that surface divided by the vacuum permittivity.

The Biot-Savart Law is a foundational equation in electromagnetism that calculates the magnetic field generated by a steady electric current. It states that the tiny magnetic field created by an infinitesimal current element is directly proportional to the current and inversely proportional to the square of the distance from the source.
