Contribution to Conics
Pascal wrote "Essay on Conics" in 1640 which included Pascal's Theorem: if any six points are drawn on a conic section, the joining lines will form a hexagon. If these lines are then drawn out to a line, they will meet at three points on this straight line. This theorem contributes to the understanding of the relation between conic sections and lines.

INTERESTING FACTS
- Private facility- pay a fee to cross
- Draws over 800,000 visitors a year
- Originally made of hemp ropes and cedar
- Replaced with wire cables in 1903
- Completely rebuilt in 1956
SOLAR FURNACE
- Uses parabolic shape
- The sideways dome-like shape shows parabola
- Mirrors concentrate light energy onto the focus
- Temperature reaches 6,330 degrees Fahrenheit
- Heat energy used as different fuel sources
Largest Solar Furnace
Located in Font-Romeu-Odeillo-Via in the Pyrenees Mountains on the France-Spain border. Contains 10,000 mirrors that reflect heat and light energy to the focus of the parabola. This energy can then be converted into electricity, used to melt steel, or to make hydrogen fuel or nano-materials.
