Key Equations

$$V(r) = \frac{q_1 q_2}{4\pi\epsilon_0 r} = \frac{Z_1 Z_2 e^2}{4\pi\epsilon_0 r}$$
$$\boxed{\ln\Lambda = \ln\left(\frac{b_{\max}}{b_{\min}}\right) = \ln\left(\frac{\lambda_D}{b_{90}}\right) \approx \ln\left(1.6\times10^4 \frac{T_e^{3/2}}{n_e^{1/2}}\right)}$$
$$\nu_{ei} \approx 6\times10^{-3} \text{ s}^{-1}$$
$$\frac{dP_{ei}}{dt} = -m_e n_e \nu_{ei}(u_e - u_i) = -m_i n_i \nu_{ie}(u_i - u_e)$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
