I spent almost 2 weeks reading a 4 -part series on Elon Musk, Telsa, SpaceX and the goal of Getting to Mars, and First Principles Thinking on Wait But Why. The posts are from 2015, but are still relevant today given what we know about the success of Telsa and SpaceX. As I read through each post, I felt like I was going deeper and deeper into a rabbit hole of the importance of engineering, physics, and the need to solve the world’s biggest challenges. By the end, I felt myself asking why more companies aren’t trying to solve big problems and why governments aren’t taking the issues of climate change, population growth, and the probability of humanity being wiped out by a man-made or natural disaster seriously. I highly recommend reading the entire series for anyone interested in science, tech, engineering, and entreprenuership.
