About

Hi! My name is Dr. John, and I have a Ph.D. in physics (so no medical advice on this channel!). The major take-a-way I'd like to share is that physics is literally all around us... and it's messy. My goal is to show why this is true, and demonstrate how physics can be used to understand the basic principles behind nearly everything. Whether it’s the physics behind atomic weapons or ancient Egyptian technologies, no topic is off limits. My target audience consists of students, teachers, life-learners, and those curious about the science governing the world around them. If this sounds like your cup of tea, subscribe to my channel & share with your friends and family :) Thank you for watching my videos, and I look forward to exploring these topics together!
