Big Idea – We can describe, measure, and compare spatial relationships. to build on students' knowledge of symmetry and develop students' reasoning with properties of symmetry to develop an ...

(Nanowerk News) Thanks to Einstein, we know that our three-dimensional space is warped and curved. And in curved space, normal ideas of geometry and straight lines break down, creating a chance to ...

Watch out — You can get different results depending on how you mesh the model. Second-order shell elements: Meshing the thin band with secondorder-shell elements produces precise curvilinear geometry.
