What Is Time? One Physicist Hunts for the Ultimate Theory | Wired Science | Wired.com: “I’m trying to understand how time works. And that’s a huge question that has lots of different aspects to it. A lot of them go back to Einstein and spacetime and how we measure time using clocks. But the particular [...]

Iceberg breaks in Antarctica not where expected: “With the dramatic crash of an iceberg against a glacier that dislodged a massive new chunk of ice, the mysterious continent of Antarctica once again did the unexpected.” A big chunk of extra credit if you can figure out what happened and why it might matter (both for [...]

Observatory – Some Fish Use UV Patterns to Recognize Species – NYTimes.com: “The work provides support for the idea, suggested by others, that the ultraviolet part of the spectrum may serve as a way for some species to communicate secretly, in ways invisible to creatures that cannot see UV.” Fascinating! We’ll start covering the electromagnetic [...]

Here are the notes from today on our continuing studies of waves… – What are the three categories of waves? – What are the three types of mechanical waves? – How are electromagnetic and mechanical waves different? – What is another name for matter waves? Here’s a nifty site with good info if you need [...]

Today, we continued our studies of waves and highlighted some of the connections we’ll have in the future with our study of the electromagnetic spectrum. In the meantime, here are our main points from today… The Four Properties of a Wave Frequency = Hz Amplitude = amount of energy/displacement in a wave Wavelength = ? [...]

Here are the questions we covered in our study of waves today. If you didn’t get enough info, see section 15.1 of your book. Your Homework is to please make sure you have a basic grasp of these ideas so that we can start moving ahead tomorrow… What is a wave? What types of things [...]

Wow… effective!

The Mariana Trench To Scale [Pic] | I Am Bored: “The Mariana Trench To Scale” This is just too cool. Remember, we know more about the surface of our moon than we do about the bottom of our oceans. Yay Pascal!
