Well, if you stop and thought about the two words, you just might be able to come up with a logical conclusion. Since a parabola is a U-shape, let's take a look at what this shape looks like in a drawing again and see if you can come up with a conclusion all on your own. Okay, now think of the two words: minimum and maximum. What do they mean? Which of the two parabolas do you think just might indicate minimum and which just might indicate maximum?

Fun with the Impossible Penrose Triangle I found this delightful animation today: The ball is traveling around a shape that can’t exist in our real world: the Penrose triangle. This illusion is the basis for some cool art, like Escher’s Waterfall. And I’m using it in my Math You Can Play books as a design on the back of my playing cards: Want to Play Around with the Penrose Triangle?

Physics Flash Animations We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. Also included is the minimum version of the Flash player that is required; the player is available free from The categories are: In addition, I have prepared a small tutorial in using Flash to do Physics animations. Bar modelling- a powerful visual approach for introducing number topics Building on my recent post about a taxonomy for deep learning in maths, I have been trying to think a bit deeper myself about what each type of ‘deep learning link’ might look like. In particular, I have been researching and putting a lot of thought into what effective ‘visual models’ look like for the ‘key nodes’ I have previously identified as the most important foundation maths knowledge for students to master before starting their GCSE maths course. These are principally number topics. Last year I became aware of the Singapore Maths Bar Modelling approached have recently found the time to research it further. I bought some Singapore textbooks and read about the work of Dr Yeap Ban Har.

Photographer Creates Stunning Symmetric Images with Light and Reflection All Photographs (c) Ferdinand Choffray, Courtesy of Ferdinand Choffray Could symmetrical composition be part of defining beauty? Symmetry makes it attractive. This is what we've been told. Phasor Diagrams Phasor Diagrams In AC electrical theory every power source supplies a voltage that is either a sine wave of one particular frequency or can be considered as a sum of sine waves of differing frequencies. The neat thing about a sine wave such as V(t) = Asin(ωt + δ) is that it can be considered to be directly related to a vector of length A revolving in a circle with angular velocity ω - in fact just the y component of the vector. Transformations of the Sine and Cosine Graphs Transformations of the Sine and Cosine Graph – An Exploration By Sharon K. O’Kelley This is an exploration for Advanced Algebra or Precalculus teachers who have introduced their students to the basic sine and cosine graphs and now want their students to explore how changes to the equations affect the graphs. This is an introductory lesson whose purpose is to connect the language of Algebraic transformations to the more advanced topic of trignonometry.

Paper Toys: Flextangles Today’s paper toys, Flextangles, are the fourth project in our collaborative series STEAM POWER: Empowering kids to explore the world through creative projects. Today’s topic is COMPUTE! Since I recently answered this question wrong, I decided it might be good idea for me to limit my math based project to something I’m good at: geometry. I’ve been itching to try making a flexagon ever since my friend Erica mentioned them, so I decided it was high time we made one.

72 Uses For Simple Household Products To Save Money & Avoid Toxins Limiting the amount of products you bring into your home will not only cut down on costs at the grocery store but will keep you and your family healthier.
