Advice for stirring your online community and fostering engagement

When you enter into any new area of science, you almost always find

yourself with a baffling new language of technical terms to learn before you can converse with the experts. This is certainly true in astronomy both in terms of terms that refer to the cosmos and terms that describe the tools of the trade, the most prevalent being the telescope. So to get us off of first base, let’s define some of the key terms that pertain to telescopes to help you be able to talk to them more intelligently. The first area of specialization in telescopes has to do with the types of telescopes people use. The three designs of telescopes that most people use are the Refractor, the Reflector and the Schmidt Cassegrain telescope. The refractor telescope uses a convex lens to focus the light on the eyepiece. The reflector telescope has a concave lens which means it bends in. It uses mirrors to focus the image that you eventually see. The Schmidt Cassegrain telescope uses an involved system of mirrors to capture the image you want to see. A binocular telescope uses a set of telescopes mounted and synchronized so your view of the sky is 3-D. Beyond the basic types, other terms refer to parts of the telescope or to the science behind how telescopes work. Collimation is a term for how well tuned the telescope is to give you a good clear image of what you are looking at. You want your telescope to have good collimation so you are not getting a false image of the celestial body. Aperture is a fancy word for how big the lens of your telescope is. But it’s an important word because the aperture of the lens is the key to how powerful your telescope is. Magnification has nothing to do with it, its all in the aperture.

Airbus exploring double-level airplane seat design
гей онлайн

If you’ve seen images of the infamous double-level airplane seat concept and thought “that’s never going to happen” — maybe think again.

Aviation start-up Chaise Longue, the brains behind the controversial dual-level seat, announced today it’s “exploring some early stage concepts” with aviation giant Airbus.

This collaboration with an aircraft manufacturing heavyweight is a significant step in this seat design’s journey from college student project to potential in-air reality.

Designer and Chaise Longue CEO Alejandro Nunez Vicente tells CNN Travel he’s thankful Airbus sees “the true potential of two-level seating.”

An Airbus representative confirmed to CNN Travel that “Chaise Longue is exploring some early stage concepts with Airbus on two-level seating solutions for Airbus commercial aircraft.”

The representative added that “given the nature of this early phase level,” Airbus preferred “not to further comment at this stage.”
The crux of Nunez Vicente’s Chaise Longue seat design is the removal of the overhead cabin to allow two levels of seats in a single aircraft cabin.

The idea is that travelers would have the option of booking the top row or the bottom row — and while the lower level might look less-than-appealing in photos, bottom passengers would be able to stretch out their legs and enjoy extra leg room. The top level is also designed to give “larger recline angles” and “leg-stretching possibility” than your average economy airplane seat, says Nunez Vicente.

Nunez Vicente initially developed the design for economy cabins before last year premiering a business class/first class iteration.

CNN Travel tested out early prototypes of both concepts and concluded that while the lower level has definite claustrophobia potential, the increased leg room could cancel out the potential cabin fever for some passengers.
