If you collected all of Earth’s water into a sphere, how big would it be?--not that big, so be good to it.

If you collected all of Earth's water into a sphere, how big would it be?

All Of Earth's Water In A Single Sphere 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 diameter would be roughly the distance from Salt Lake City, Utah to Topeka, Kansas.

Spherical spacetime time is a four-dimensional continuum of space and imaginary time forming the surface of a sphere in five dimensions.

This is a Polar map projection.  It's  a systematic transformation of the latitudes and longitudes of locations on the surface of a sphere onto a flat surface.  All map projections introduce distortion.   But since a map is easier to carry around than a globe the destortion may be aceptable  https://www.google.com/amp/www.winwaed.com/blog/2010/01/11/polar-maps-and-projections-part-1-overview/amp/

Included in this download are 4 posters. Posters include pictures and formulas for volume, lateral surface area and total surface area of a right square pyramid, a right circular cylinder, a right circular cone and a sphere.

Here is the geometric solids supplement to my other math word walls. Included are 6 shape posters, their formulas for

Here is a set of 242 interlocking bevel gears arranged to rotate freely along the surface of a sphere. This sphere is composed of 12 blue gears with 25 teeth each, 30 yellow gears with 30 teeth, 60 orange gears with 14 teeth, and 140 small red gears with 12 teeth. I also found 3 other gear tooth ratios that will work, but this one was my favorite because the small gears emphasize the shape of a truncated rhombic triacontahedron.

cylinder, cone and sphere – three types of space figures that are not polyhedrons. – These figures have curved surfaces, not flat faces. – A cylinder is similar to a prism, but its two bases are circles, not polygons. Also, the sides of a cylinder are curved, not flat. – A cone has one circular base and a vertex that is not on the base. – The sphere is a space figure having all its points an equal distance from the center point.

You can assemble the globe easily. The reversible globe packs two faces of the world in one volume.  You can flip the surface of a dodecahedral globe inside out and transform to a cube by re-assembling six units.

GeoGrafia's Flippable Globe "cube in dodeca" ~ this paper globe you can assemble yourself - "The reversible globe shows both simple outline of lands on one side (dodecahedron) and complex political borders on the other side (cube).

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.

I decided for my contribution to the exhibition entitled Fragility at Sheoak Gallery at Fingal to do Raku’d Balloon Bowls and Garden Totems. So I set about making Balloon Bowls and Garden…read more →

By covering the skin of taxidermy animals with transparent glass spheres, sculptor Kohei Nawa magnifies the underlying surface and distorts the surrounding light to create a pixilated “husk of light.” Reflective light on glass spheres.
