Gotta say it's really sad that I'm Junior's lifeline when it comes to getting physics homework done. When I left the gym early this evening, I turned on my phone and there were four messages from Junior and his little brother asking when I was getting home and could I help them with their homework.
"I have physics, and I don't understand it," Junior told me. When I called him back, it was pretty late and I asked if he had gotten any of it done. "Yeah, some," he said. "There's just two parts I don't understand."
One of them was scientific notation and how to convert back and forth between scientific and standard. There were some problems where you had to multiply and divide numbers in scientific notation and I vaguely remembered you could just add and subtract the powers of 10 (the integers), but I wasn't really sure.
"Call Picasso," suggested Junior. "He's smart."
"Yeah, you're right," I said, and we called him. He's done it at Curie, too, and he thought yes, we could do that. So we did. (If we were wrong, you can call us out in the comments.)
Then we went back and checked something he had done earlier. Junior was supposed to explain and make a sample graph of a direct relationship between two things. He explained it in general and made a general graph, but he hadn't given a specific example. When we looked back, he came up with a good one: "The more kids you have, the more you have to do laundry."
"You see that from having your little brother around, right?" I said. They laughed. (There's nothing like a new baby in the house for laundry.) So he put labels on his graph--I think loads of laundry was the x-axis and number of kids was the y-axis.
