Chat Preparation Essay

Log into the Moodle, click on the Natural Science II course link, and then on the forum link in session 21, Unit 53. Post your definition to the forum. Read any other posted definitions.

We talked last week about the elegance of Maxwell's equations, and the impulse to seek the simplest answer. How did the discovery of radioactivity challenge scientists in their attempt to explain matter in the most simple, fundamental terms?

Mastery Exercise

Bring any questions you have to chat. Then return and attempt the exercise as many times as necessary to achieve an 85% or better score.
