Continuing his brilliant series of videos on the unappreciated wonders of engineering that surround us, here’s Bill Hammack, aka Engineer Guy, on the truly amazing process required to produce a common incandescent light-bulb filament. Bill has a fantastic ability to produce short, engaging, entertaining video segments that will appeal to and educate both the totally uninitiated and those who, like myself, are foolish enough to think we know a thing or two. [Thanks, Bill!]
