LINE AS VALUE  I can't explain why I find this so intriguing. Squiggly lines become a sphere. Majorly cool.

This picture shows the size of a sphere that would contain all of Earth's water in comparison to the size of the Earth. The blue sphere sitting on the United States, reaching from about Salt Lake City, Utah to Topeka, Kansas, has a diameter of about 860 miles (about 1,385 kilometers) , with a volume of about 332,500,000 cubic miles (1,386,000,000 cubic kilometers).

This is the first in a sequence of two artist's impressions that shows a huge, massive sphere in the center of a galaxy, rather than a supermassive black hole. Here a star moves towards and then smashes into the hard surface of the sphere, flinging out debris. The impact heats up the site of the collision. Image: Mark A. Garlick/CfA

Michael Freedman proves Poincaré conjecture in dimensions equal to 4.| Richard Hamilton's program started in his 1982 paper introduced the Ricci flow on a manifold showed how to use to prove some special cases of Poincaré conjecture. For compact 2-dimensional surfaces without boundary, if every loop can be continuously tightened to a point, then surface is topologically homeomorphic to 2-sphere. Poincaré conjecture, proved by Grigori Perelman, asserts the same is true for 3-dimensional…

Fill the balloon with water . This image illustrates why you don't completely fill the balloon you should always leave some room in the neck of the balloon, then  as the form dries the pressure has somewhere to go and your clay wont split like that.

Students love this project! They take everyday objects and create a 3D model including a pyramid, cylinder, sphere, cone and prism. The then calculate the surface area and volume of each shape to demonstrate their understanding of formulas.
