But under the laws of gravity, a parabola is an impossible shape for an object that's gravitationally bound to the Earth. The math simply doesn't work out.

Parabolic reflectors are reflectors made in the shape of a parabola, or a curve on which all points are equidistant from a focus point as well as a line known as the directrix. To us, it just ...

Parabolic reflectors for solar applications are nice stuff, and making your own is a great project in itself. ... Here´s where the vacuum is needed to force the film into parabolic shape.

Researchers have developed a new way to produce and shape large, high-quality mirrors that are much thinner than the primary mirrors previously used for telescopes deployed in space. The resulting ...

That newly introduced liquid forms a “perfect parabolic shape,” which the polymer then grows upon to form the mirror’s base. As Space.com notes, ...

The parabola line is now a separate graphic object on the screen. Use the "Shape Fill" and "Shape Outline" buttons on the "Shape Styles" panel to customize the color of the parabola curve if you want.

Framework for solving parabolic partial differential equations could guide computer graphics and geometry ... This framework can help better analyze shapes and model complex dynamical processes.

Schematic diagram of a parabolic reflector. Incoming sound is directed to the microphone placed at the focus of the parabola-shaped reflector. The property of the parabolic shape to reflect all sound ...
