(EndPlay Staff Reports) - Welcome, Summer solstice .
June 21 is the longest day of the year in the Northern Hemisphere, marking the sun's gradual trek back into our lives since the winter solstice, the shortest day of the year. In the Southern Hemisphere, today brings the opposite – winter solstice.
How? The sun rises a bit earlier each morning then sets a minute or two later every night, bringing a little more light throughout this process, reported The Huffington Post .
As the Earth orbits the sun throughout the year, the earth's axial tilt causes the sun to change position in the sky, according to UniverseToday.com .
Another interesting aspect of this solar ritual is the spring equinox, the halfway point when the length of day and night is equal everywhere on Earth.
The summer solstice brings different amounts of daylight, depending on location. For example, New York City will get about 15 hours of sunlight today, while Fairbanks, Alaska, will get 21 hours. The sun doesn't set at all at the North Pole, reported The Huffington Post.

The Underdog | $9.99 | eBooks.com | From the Hardcover edition. Over the next two years, Josh ventures to Spain to try his hand at bullfighting, sumo-wrestles 500-pound men, perfects his backward running in India and at the Golden Shrimp “retrorunning” race in Italy, and bonds with his family at the Sauna World Championships–because sometimes it takes a blistering 220-degree sauna to bring loved ones together. Unfortunately for her, he’s just getting started. Too bad he’s a 129-pound data entry clerk whose wife, Tara, has only three simple requests for their life together: direct sunlight, a dining room, and a bathtub. On the heels of a fourth-place finish (out of four contestants) in the lightweight division of the U.S. In The Underdog , what begins as a means to get Tara her bathtub evolves into a charming story of courage, adventure, and just a little bit of insanity. Since none of these exist in their 250-square-foot San Francisco apartment, Josh sets off on a quest to become the provider his wife wants him to be. The problem is that he does it in a way that most people in their right minds would never consider: he enters the most grueling and unusal contests in the world. He wants a fun career, exciting adventures, a happy wife who’s proud of him, and really big muscles that strangers can’t help but admire. National Armwrestling Championships, Josh gets a spot on Team USA and travels to Poland to face “The Russian Ripper” in the World Championships–and Tara finds herself wishing her husband would go back to data entry. By turns hilarious, harrowing, and inspiring, The Underdog documents one man’s ballsy attempt to live the American dream to the extreme. |

Light Therapy: Ultraviolet, Photodynamic Therapy, Light Sensitivity, Biophotonics, Niels Ryberg Finsen, Dark Therapy, Colorpunctur | $18.60 | BetterWorld.com - New, Used, Rare Books & Textbooks | The higher energies of the ultraviolet spectrum from about 150 nm ('vacuum' ultraviolet) are ionizing, but this type of ultraviolet is not very penetrating and is blocked by air. Although ultraviolet is invisible to the human eye, most people are aware of the effects of UV through the painful condition of sunburn, but the UV spectrum has many other effects, both beneficial and damaging, to human health. It is named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the color violet. Most ultraviolet is classified as non-ionizing radiation. Chapters: Ultraviolet, Photodynamic therapy, Light sensitivity, Biophotonics, Niels Ryberg Finsen, Dark therapy, Colorpuncture, Chronotherapy, Norman E. It can cause chemical reactions, and causes many substances to glow or fluoresce.

He called them "oxidizing rays" to emphasize chemical reactivity and to distinguish them from "heat rays" at the o... Pages: 26. Excerpt: Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400 nm, and energies from 3 eV to 124 eV. In 1801, the German physicist Johann Wilhelm Ritter made the hallmark observation that invisible rays just beyond the violet end of the visible spectrum were especially effective at lightening silver chloride-soaked paper. UV light is found in sunlight and is emitted by electric arcs and specialized lights such as black lights. The discovery of UV radiation was associated with the observation that silver salts darken when exposed to sunlight. |
