Parabola

Those shapes are parabolas.

Select the directrix of the new parabola...

Parabola by Directrix Focus

A parabola defined by its directrix and focus

Construct a parabola with this directrix

Select the focus of the new parabola...

I had just taken trigonometry in high school, I learned about the parabola and how it could concentrate rays of light to a single focus.

Vertical Parabola by Three Points

A vertical parabola constructed through three points

Construct a parabola through this point

Select a point for the new parabola to go through...

Both radars are supported from a 34 m parabolic antenna.

And Dr. Terry Erwin, in 1983, called the canopy, the last biotic frontier.

(a) Radars with mechanically controlled beam direction using parabolic reflector antennas.

Both radars are supported from a 34 m parabolic antenna.

Both are supported from a 34 m parabolic antenna.

They have to track the sun, because they have to be pointing directly at the sun.

Only objects being in the actual field of view given by the mechanical direction of the parabolic reflector antenna can be detected and measured

They take all the parallel incoming rays and focus it to a single spot.

We looked at a way to break up a parabola into individual petals that would track.

(a) Radars with mechanically controlled beam direction using parabolic reflector antennas.

Well, the only way to experience zero g on Earth is actually with parabolic flight, weightless flight.

Remember we used to throw things away, and we'd point to away?

The primary network topology is a star, using a central inexpensive mini hub station (dish size 1.5 2.4 m).

In particular, parabolic aircraft flights, for both scientists and engineers, provide a good means of access to microgravity.

Only objects in the actual field of view given by the mechanical direction of the parabolic reflector antenna can be detected and measured

Much later, Robert Maillart's bridges, which optimize structural form with a calculus curvature almost like a parabola.

Conventional radars with a large parabola antenna cannot continuously observe an orbital object for more than a fraction of a second unless its orbit is given beforehand.

These programmes were received in 2,400 villages in several Indian states using specially designed three metre parabolic antennas, front end converters and television sets.

One of the challenges that canopy researchers are attacking today is trying to understand the amount of carbon that is being sequestered.

We had a press conference, we announced our intent to do one zero g parabola, give him 25 seconds of zero g.

So we did a second parabola.

and you shall set the turban on his head, and put the holy crown on the turban.

And thou shalt put the mitre upon his head, and put the holy crown upon the mitre.

And thou shalt put the mitre upon his head, and put the holy crown upon the mitre.

The largest radar tracking facility in western Europe at the Research Establishment for Applied Science (FGAN) in Wachtberg Werthhoven (Germany) was using a 34 metre parabolic dish antenna.

It's a parabolic Scheffler solar cooker.

A Ku band version (12 14 GHz) with 50 cm dish, compatible with EUTELSAT or INTELSAT, is also planned.

And this was a company where I built parabolas, I took metal shop, and I remember walking into metal shop building parabolas and Stirling engines.
