It's wonderful to read about this sort of teacher. Everyone should have at least one such, in high school.
I was lucky enough to have had two such, one for general science, and the other for physics. Definitely both were "instrumental" to my education and to help solidify what I thought I wanted to do when I grew up. And I've been using what they taught me to this day.
Counter-intuitively perhaps, the general science teacher, who graduated with architecture degree from undergraduate school, ended up getting a PhD in ... art history! Obsessed with ancient Rome.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
