I pasted the photo into ChatGPT. Here's what it came up with. The whiteboard contains several famous physics equations. Here are the ones I can identify: 1. *Einstein's field equations (General Relativity):* \[ E = \frac{8\pi G}{3} \left( \rho + \frac{\Lambda}{8\pi G} \right) \] \[ R_{\mu\nu} - \frac{1}{2} R g_{\mu\nu} + \Lambda g_{\mu\nu} = \frac{8 \pi G}{c^4} T_{\mu\nu} \] 2. *Planck's law:* \[ E = h\nu \] \[ E = \frac{hc}{\lambda} \] 3. *Schrödinger equation (Quantum Mechanics):* \[ i\hbar \frac{\partial \psi}{\partial t} = \hat{H} \psi \] 4. *Lagrangian mechanics:* \[ L = T - V \] where \( T \) is kinetic energy and \( V \) is potential energy. 5. *Newton's law of universal gravitation:* \[ F = G\frac{m_1 m_2}{r^2} \] 6. *Friedmann equations (Cosmology):* \[ \left(\frac{\dot{a}}{a}\right)^2 = \frac{8\pi G}{3} \rho - \frac{k}{a^2} \] 7. *Coulomb's law:* \[ F = k_e \frac{q_1 q_2}{r^2} \] 8. *Boltzmann's entropy formula:* \[ S = k_B \ln \Omega \] 9. *Maxwell's equations (Electromagnetism):* \[ \nabla \cdot \mathbf{E} = \frac{\rho}{\epsilon_0} \] \[ \nabla \times \mathbf{B} - \mu_0 \epsilon_0 \frac{\partial \mathbf{E}}{\partial t} = \mu_0 \mathbf{J} \] 10. *The cosmological equation:* \[ \ddot{a} = -\frac{4 \pi G}{3} (\rho + 3p) a + \frac{\Lambda}{3} a \] 11. *Thermodynamic identity:* \[ dU = TdS - PdV \] This collection of equations spans various domains of physics, including quantum mechanics, general relativity, electromagnetism, thermodynamics, and cosmology.
