Today was the Treasure Valley regional prelims for the middle school "National History Day" competition. Each year, middle school students have the chance to write an essay, build a website, or prepare a documentary honoring some great event in history. This year's theme was Innovation and how it impacted history, and Mark did a video documentary on the evolution of the transistor. The transistor certainly is something that people just take advantage of today, and don't even realize how it impacts their lives. Mark's video documentary is embedded below, and I particularly like the part that says that if cell phones used vacuum tubes a cell phone today would be ten-and-a-half feet tall. :-) Watch and enjoy.
