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.

Look of the Week: Forget the naked dress, Kendall Jenner makes the case for underwear as outerwear
kraken тор браузер

On Monday, Kendall Jenner stepped out onto the L’Oreal Paris womenswear runway in a scarlet red Mugler gown that might have looked familiar to anyone with a sharp memory of 1999.

The front of the dress was slashed open across Jenner’s right shoulder, exposing a matching denier bra. The peekaboo moment conjured up memories of another example of fashionable flashing: Lil’ Kim’s purple embellished jumpsuit at the VMAs 26 years earlier. On the red carpet, Kim’s left breast was almost entirely revealed by an asymmetrical cut — a mirror image of Jenner’s neckline — save for a matching purple nipple pasty.
Jenner’s Mugler moment was just the latest example of a resurging tendency for underwear as outerwear. At the Nensi Dojaka runway show in London earlier this month, boxy blazers were shrugged over strappy bras while paneled bustiers in sheer fabric were paired with capri trousers and reimagined as going out tops. Brasseries were even left exposed to the elements at Erdem — a departure for a house beloved by both British acting royalty (Kristen Scott Thomas) and actual royalty (the Duchess of Cambridge). Dolce & Gabbana got the memo, too, showing satin corsets, garter belts and Madonna-esque cone bras at Milan Fashion Week on Saturday. Florence Pugh even wore one of the label’s risque designs in her first British Vogue cover last week — the circle neckline of her puff-shouldered black dress scooping just above the belly button, acting as a full-frontal frame for her bra.
But the trend extends beyond just the runways. During the first performance of her “Short n’ Sweet” tour on Monday, singer Sabrina Carpenter took to the stage in a custom Victoria’s Secret bodysuit and stockings. Hand-adorned with over 150,000 crystals, the strapless pink lace-trimmed leotard took over 140 hours to make. On Monday,YouTube star and singer Jojo Siwa inverted the fad by donning a codpiece for a headline-grabbing cover shoot with LadyGunn magazine. The 15th century undergarment was bedazzled with flesh-colored gemstones.
