This means that the shortest path between Los Angeles and London on Earth’s map is not a straight line (red), but rather a curve (purple) that follows a line on the sphere that is Earth.

So, the pilots, who deal with spherical geometry on a daily bases, have to go through mathematical calculations discussed here, along with other more complex derivations, every time they want to analyze the direction or the path of their journey. A perfect career choice for people who want to do math all day long.

]]>After reading this cool post on applications of spherical geometry, I decided to look for all sphere-related objects in my life. This week I saw many spherical objects:

-The fake wooden or plastic or some kind of egg that Mr. Honner showed us on 3/9/11, which also reminds me of lunes.

– Google Earth, at which I usually look at my home only.

-I saw millions and millions of black frog eggs, so many…. enough to fill my stomach

-The copper ornament that Mr. Honner was juggling during Major selection [he doesn’t seem to juggle well]. Three of the copper ornaments might be infected all because Mr.Honner unleashed water on shapes and used them as test subjects… Poor Shapes..

-On 3/8/11, I saw mini circle shaped pizza during lunch. So cheap… Obviously, I went for some other food.

-Your head is related to spherical geometry.

-I saw many pictures, more pictures and more pictures of spheres…. All looked beautiful.
