Today in Math

Today in math we learned about vectors with non-real numbers, how interesting. We did our daily warm-ups and went over homework. I thought the homework from last night was easy. After that, we took notes. We learned that the absolute value of the complex number z = a+bi is a + bi = square root of "a" squared + "b" squared. It's that easy. The trigonometric form of a complex number is z = r(cosa + i·sina). We learned a bunch of complicated stuff.

Today in History

Today in history was just like any other day. We took notes on World War I. After that we saw a movie. It was "The Great Train Robbery." It was a milestone in film making. It was one of the first "narrative" films. It first came out in 1903. It was sold out for two years. At the end of the film, one of the robbers points his gun at the camera and starts to shoot. People back then didn't know it wouldn't hurt them. They freaked out thinking they were going to get shot. It was also one of the first "colored" films. The whole screen was just one color and it went with the mood. I thought it was funny how they made it. The people who got shot were over dramatic. I thought it was an okay film. After the film, we read an article on daily life in a trench during WWI. It was a really hard life. There was death, giant rats, lice, other pests, disease, and horrendous smells everywhere. We then answered questions afterwards.
