This Week in Physics
If you have not yet subscribed to this blog, you should. Look on the right side of this page (if you’re on a computer) or scroll to the bottom (if you’re on a phone) to find the subscription link. If you have not yet subscribed to Remind for this class, text @shellyburg to 81010. Read on…
For Tuesday please take notes on Unit 1 Podcast 2: Interpreting Graphs of Position v Time. (Remember that your podcast notes go in a notebook, not your composition book, although you need to bring both books to class.) We will debrief this in class as well as tie in the discoveries we made while doing our uniform motion experiment. We will also progress through some graph interpretation activities using the Moving Man application from PhET.
As the week progresses we will spend time in the media center learning how to write lab reports for this course. It is essential that you can log into your @alstudent.org account in order to work on the report, so be sure you have confirmed your login information before class on Wednesday. Your lab report for this class is due next Wednesday, September 13 at the start of your class period. Documents you will need to write the lab report are:
Cool Science of the Week
Imagine finding out that someone invented an iPhone long, long ago…A similar thing has just happened to mathematicians! We have long regarded Greek astronomer Hipparchus to have been the founder of trigonometry in 120 BC, but researchers have finally decoded a stone tablet found in the early 1900s (by the guy who was the inspiration for Indiana Jones!), and it turns out this tablet shows that trigonometry was founded long before Hipparchus did his work…3700 years ago around the year 1700 BC in Babylon! That’s 1900 years earlier in a totally different part of the world! (The tablet, known as Plimpton 332, was found in Babylon’s ruins near Baghdad, Iraq. Babylon was a major city in ancient Mesopotamia.)To mathematicians and scientists, this discovery is like finding out someone invented an iPhone 1900 years ago in the year 100 CE!
