Epsilon Is Greater Than

I'm a former high school physics and general science teacher who just loves science too much to stop teaching it. I call my channel "epsilon is greater than" because the heart the symbols form represents my love for learning and teaching science. My first video series is about facts that science has uncovered about our world, particularly ones that have come under pseudo-scientific criticism of late. After that, it's wide open. What would you like me to talk about? If you could ask a professional science teacher a question, what would it be? Let me know in the comments. I'd like to make this a two-way conversation.
