Music and math: The genius of Beethoven - Natalya St. Clair Natalya would like to acknowledge the amazing support of her friends Wendy Cho, Carolyn Meldgin, Antoinette Evans, Will McFaul, Aaron Williams, and her fantastic students and colleagues at Countryside School and Math Zoom, especially Chris Antonsen, Kim File, Harold Reiter, Jeffrey Huang, Kashyap Joshi, and Priscilla Wang. Frequency and Music Our abilities to recognize patterns in music using sine waves help to “see” innovative ways of problem-solving. For teachers, a great introduction to teaching frequency theory can be found here ( Students might enjoy discussing the activity found in NCTM Illuminations to explore more with the mathematics of music. Sound travels through energy in the form of wavelengths, which can be described using the function of the form f(x) = A sin (B x). For a nice overview of sine waves, watch The Math of Music.

Celiac Disease and Gluten: The War Inside Your Body Celiac Disease and Gluten: The War Inside Your Body by Jordan Reasoner, guest author (Note: We asked Jordan if he would share this article with us, as we knew it would be particularly helpful to the newly diagnosed celiac (as well as some “seasoned”). Fingerprint: Simulated Annealing FA tries to explain the dependencies among the observed variables in terms of a smaller number of unobserved latent variables, or factors, without loss of information. Statistically, the dependencies between variables are defined by the covariance. It can be used for dimensionality reduction, detecting structure in the relationships between variables, and visualization purposes. Model dose Which is to remind us that this is precisely how some young women see themselves - gross and revolting - as they navigate through womanhood and its many natural challenges. That being said, don't add to the noise with negativity and disparagement.

Web UI Design Best Practices by UXPin explains techniques spanning visual design, interface design and UX design. Illustrated example of changing variables in double integrals - Math Insight Properties of an example change of variables function A common change of variables in double integrals involves using the polar coordinate mapping, as illustrated at the beginning of a page of examples. Here we illustrate another change of variables as a further demonstration of how such transformations (x,y) = \cvarf(\cvarfv,\cvarsv) map one region to another. We use the change of variables function \begin{align} (x,y) = \cvarf(\cvarfv,\cvarsv) = (\cvarfv^2-\cvarsv^2, 2\cvarfv\cvarsv).
