"Tell me, and I forget. Teach me, and I remember. Involve me, and I learn" ~Benjamin Franklin. Growing up, active learning has been very much a part of my education journey. The process has allowed me to delve into interesting subjects. I am thankful for the many resources that have helped satisfy my curiosity about various STEM topics. And this is the reason for creating this blog – a platform to share some of my learnings and thoughts about physics. My other passion being entomology and as a self taught macro photographer, I am also sharing pictures of many tropical insects in this blog. Feel free to point out any mistakes, and I welcome your input on anything I might have missed.

Most readers familiar with the behaviour of EM waves in materials will recognise the following equation: \(\chi (\omega) = \frac{\omega_p^2}{(\omega_0^2-\omega^2) \pm i\omega \gamma} \) Which is the susceptibility of a material approximated by the Drude-Lorentz model. This model treats the electrons as classical charged particles bound to their respective atoms/ chemical bonds by a spring…
