🎓 Learning Paths

• Blackbody: $E_b = \sigma T^4 \to \lambda_{max} T = 2898 \mu\text{m}\cdot\text{K}$
• Enclosures: $F_{ij} \to \frac{1-\varepsilon_i}{\varepsilon_i A_i} \to \text{Radiosity } J_i$
• Shielding: $q_{with} = \frac{1}{N+1} q_{without}$ ($N$ shields)
• Gas Radiation: Leckner correlation $\to \varepsilon_g(P_w, P_c, L)$

• Stefan-Boltzmann: $E_b = \sigma T^4 \quad (\sigma = 5.67\times 10^{-8})$
• Wien's Law: $\lambda_{max} T = 2897.8\,\mu\text{m}\cdot\text{K}$
• Reciprocity: $A_i F_{ij} = A_j F_{ji}$
• Summation Rule: $\sum_{j=1}^N F_{ij} = 1$
• Surface Resistance: $R_{surf} = \frac{1 - \varepsilon_i}{\varepsilon_i A_i}$
• Space Resistance: $R_{space} = \frac{1}{A_i F_{ij}}$
