Welcome to my channel! My name is Ed Rogers and I'm a licensed land surveyor, civil engineer and high school teacher. My specialty is making complex ideas understandable. My favorite topics to cover are geometry, trigonometry, surveying, engineering, robotics and chess. If you have a question in one of these fields and you can't find a video where I've addressed it, please feel free to e-mail me and I would be glad to take a crack at it! Helping people access and master new ideas is what gets me out of bed in the morning. How can I help you?
