INSIGHT

Three Pillars of Physics

  • Physics rests on three pillars: quantum mechanics, relativity, and thermodynamics.
  • Thermodynamics, while crucial, is often overlooked due to the focus on the more revolutionary quantum mechanics and relativity.
INSIGHT

Particle Zoo

  • While our world primarily consists of quarks and electrons, other particles are vital for understanding interactions.
  • These particles, though short-lived, play a crucial role in a unified theory of everything.
INSIGHT

Philosophy in Physics

  • Philosophy plays a crucial role in physics by posing fundamental questions about reality.
  • While physics provides answers, philosophy helps frame the right questions, especially in interpreting quantum mechanics.
