    Study Notes

    • Astrophysics is a branch of Modern Physics, developed around the turn of the 20th century when scientists gained a better understanding of matter, energy, and atoms.
    • Electricity, Light, and Magnetism were found to exist as one according to James Clerk Maxwell's Electromagnetic Theory. This theory also led to the Lorentz Force and the discovery that light has both wave and particle properties.
    • Albert Einstein's special theory of relativity was developed based on the invariance of Maxwell's electromagnetic equations. He used the Lorentz Transformation Variable to establish the relationship between space and time, recognizing that they can change due to the properties of light.
    • Exoplanets are planets that orbit around other stars, and the search for exoplanets is driven by the goals of finding habitable worlds for humans and searching for extraterrestrial life.
    • Orbital resonance is a phenomenon that occurs when the orbits of two celestial bodies have a regular, periodic gravitational influence on each other, preventing collisions.
