let students explore concepts by manipulating an expression—or a graphical representation of an expression—with things like sliders, buttons, and checkboxes. When you wrap the Manipulate command around an existing calculation, Mathematica automatically creates a sophisticated interface that lets you and your students change values and see what happens in real time. It’s truly empowering!
Now students can interact with everything from two-dimensional trajectory paths…
to Riemann sums…
to the phases of the planets…
to almost anything else you can imagine. See the Wolfram Demonstrations Project for thousands of free ready-to-use examples.
Erich Feldmeier on 08 Apr 13"The results are published in Nature Medicine today. Co-author Stanley Hazen, head of cardiovascular medicine at the Cleveland Clinic in Ohio, says that the study could signal a new approach to diet and health. In some cases, an individual's collection of intestinal microbes may be as important to their diet as anything on a nutrition label, he says. "Bacteria make a whole slew of molecules from food," he says, "and those molecules can have a huge effect on our metabolic processes.""
