Achievements in Engineering #2, Period 2 Monday
Today, the class was back inside a regular classroom, even though this one was a bit dark with the lights out and the shades pulled down. "Welcome! It's good to see that you're all back for another week," said Mike, grinning. "This week, we're going to be talking about the next achievement on our list, electricity. Oh, and just in case you guys need some more light, I've got something for you right here." He started passing out candles, one for each student.
"Believe it or not, folks, there was once a time where you needed a candle or some kind of oil lamp if you were out and about after sunset. That all changed when Thomas Edison perfected the incandescent light bulb. Problem is that you can't use a light bulb without the electricity to power it, so his next move was to develop an electricity distribution system to bring electrical powers to consumers. Edison favored a direct current system, but eventually the country adopted the alternating current system proposed by Nikola Tesla and George Westinghouse. Thanks to their work, I can flip a switch over here on the wall and we don't need those candles anymore," said Mike, turning the overhead lights on.
"I'm sure the power systems that some of you have in the future are a lot more advanced than what we have here, but the point here is that without electricity, we wouldn't have lights or computers or any sort of modern appliance that you can imagine."
