Forward thrust comes from gliding Soaring bears the relationship to flying that sailing downward relative to the air the same as thrust bears to power boating. Soaring has made notable is developed in a power-off glide by a conven contributions to meteorology. For example, soar tional aircraft. Therefore, to gain or maintain ing pilots have probed thunderstorms and moun altitude, the soaring pilot must rely on upward tain waves with findings that have made flying motion of the air. safer for all pilots. However, soaring is primarily To a sailplane pilot, "lift" means the rate of recreational. climb he can achieve in an up-current, while "sink" A sailplane must have auxiliary power to be denotes his rate of descent in a downdraft or in come airborne such as a winch, a ground tow, or neutral air.

Sailplanes are highly 171 r efficient machines; a sink rate of a mere 2 feet per second. There is no point in trying to soar until second provides an airspeed of about 40 knots, and weather conditions favor vertical speeds greater a sink rate of 6 feet per second gives an airspeed than the minimum sink rate of the aircraft. -
Sky Watch Heard Most Weekdays on WFWM, FSU's Public Supported

Moon’s cycle of lighted shapes (phases) lasts 29.53 E. days, as the phases also depend on direction of sun (appears to move 30 degrees eastward each month along zodiac). The moon is seen about 13 days growing in the evening from a slender crescent ( ) ) to Full, followed by an equal time shrinking (mainly seen in the a.m. sky) and then 3 days hidden in sun’s glare. Key Moon Phases (D) moon ½ full in evening (best for crater & mountain viewing ) & (O) full moon (see all lava plains) (Dec. ’14, 6 -O, 28 – D)) // (Jan. ’15, 4 - O, 26 - D), // (Feb. ’15, 3 – O, 25 - D) // (Mar. 5 – O, 27 – D) (Apr. 4 – O, 25 – D), // ( May 3 – O, 25 - D) // (Jun., 2- O, 27 – D)) // (Jul., 1 – O, 24 –D, 31 –O (Blue Moon)) (Aug., 22 – D, 29 – O) // (Sep., 20 – D, 27 – O (Harvest Moon)) // (Oct. 20 – D, 27 – O (Hunters’ Moon)) // (Nov., 19 – D, 25 – O) // (Dec., 18 – D, 25 – O (Long Night Moon)) (D = ½ full, O = full) THE 5 BRIGHT PLANETS (Mercury, Venus, Mars, Jupiter & Saturn): Uranus, Neptune are much dimmer.

The Blue Hours Dusk, Early September, Just Beneath the Arctic
The Blue Hours Dusk, early September, just beneath the Arctic Circle, by a tideline glacier in East Greenland. The cusp of the seasons, the cusp of the globe, the cusp of the land, and the day’s cusp too: twilight, the blue hours. At this latitude, at this time of year, dusk lasts for two or three hours. We have returned from a long mountain day: pitched climbing up steep slabs and over snow slopes to a towered summit, from which height we could see the great inland ice-cap itself. Then down, late in the day, the darkness thickening around us, and the sun dropping fast behind the western peaks. So we sit together back at camp as the last light gathers on the water of the fjord, on icebergs, on the quartz seams in the white boulder-field above our tents. Twilight specifies the landscape in this way – but it also disperses it. Relations between objects are loosened, such that shape-shifts occur. Just before full night falls, and the aurora borealis begins, a powerful hallucination occurs. My tired eyes start to see every pale stone around our tent not as boulder but as bear, polar bear, pure bear, crouched for the spring. Across the Northern hemisphere, twilight is known as the trickster-time: breeder of delusion, feeder of fantasies, zone of becomings. In Greek, dusk is called lykophos, ‘wolf-light’. In Austria, too, it is Wolflicht. In French it is the phase entre chien et loup, ‘between dog and wolf’: the time when, as Chrystel Lebas has written, ‘it is nearly impossible to tell the difference between the howling sound coming from the two animals, when the domestic and familiar transform into the wild.’ I do not know the Greenlandic word for dusk, but perhaps it would translate as ‘bear-light’. -

Guide for the Use of the International System of Units (SI) Preface The International System of Units, universally abbreviated SI (from the French Le Système International d’Unités), is the modern metric system of measurement. Long the dominant measurement system used in science, the SI is becoming the dominant measurement system used in international commerce. The Omnibus Trade and Competitiveness Act of August 1988 [Public Law (PL) 100-418] changed the name of the National Bureau of Standards (NBS) to the National Institute of Standards and Technology (NIST) and gave to NIST the added task of helping U.S. -

The Negro American has for his environment not only the white surrounding world, but also, and touching him usually much more nearly and compellingly, is the environment furnished by his own colored group. There are exceptions, of course, but this is the rule. The American Negro, therefore, is surrounded and conditioned by the concept which he has of white people and he is treated in accordance with the concept they have of him. On the other hand, so far as his own people are concerned, he is in direct contact with individuals and facts. He fits into this environment more or less willingly. It gives him a social world and mental peace. On the other hand and especially if in education and ambition and income he is above the average culture of his group, he is often resentful of its environilcg power; partly because he does not recognize its power and partly because he is determined to consider himself part of the white group from which, in fact, he is excluded. -
