One of the early lectures in Professor Lewin's physics 8.01 course at MIT. He discusses the powers of ten and the importance of measurement. Lewin also performs an experiment to determine if a person is in fact taller lying down than standing. A gre...at lecture for teachers to watch prior to teaching a lesson (38:11).

The Universe in a Nutshell: The Physics of Everything Michio Kaku, Henry Semat Professor of Theoretical Physics at CUNY What if we could find one single equation that explains every force in the universe? Dr. Michio Kaku explores how physicists may s...hrink the science of the Big Bang into an equation as small as Einstein's "e=mc^2." Thanks to advances in string theory, physics may allow us to escape the heat death of the universe, explore the multiverse, and unlock the secrets of existence. While firing up our imaginations about the future, Kaku also presents a succinct history of physics and makes a compelling case for why physics is the key to pretty much everything. (42:14)

What's the difference between accuracy and precision? Justin does an incredible job of simplifying the question while discussing the question in context for students. Great visuals! Vocabulary Focus:
Accuracy, Precision, Accurate but NOT Precise,... Precise but NOT Accurate, Accurate AND Precise.
Concept Focus:
How do you use equipment and know it is accurate?
How do you use equipment and know it is precise?
How does your own ability change the accuracy and precision of a measurement?

Powers of Ten
From powersof10.com, produced by Charles and Ray Eames
|
|
Based on the famous film Powers of Ten by Ray and Charles Eames (1977), this video depicts the scale of the Universe in factors of ten. The video begins overlooking a couple sharing a picnic in the park. Every 10 seconds the couple appears 10 times f...arther away until the viewer sees the galaxy itself. The camera then begins to zoom in on the couple in the park until we reach a magnitude of 10 ee-18, observing subatomic particles (09:01).
