The Bandgap
Over the weekend, I had the pleasure of interviewing my grandmother over the phone. Hearing her perspective on how the world functioned before semiconductors were everywhere, both funny and eye-opening. At first, she wasn’t even sure what a semiconductor was. When I explained that they’re the invisible devices inside everything from cell phones to TVs to modern cars, she laughed and said, "Well, no wonder I didn’t know, I just use the things, not build them." That got the ball rolling, and she started sharing what life was like before all of these inventions.
