I mean I know how to solve an ODE but, but luckily I'm teamed up with a civil engineer. I recently conspired with his wife to get him... -
LLightningInAJar replied to the thread Undergrad How do I stretch a laser from a beam into a sheet?.Chatgpt is the first place I went when asking about lenses. YouTube helped more.
