In this video, we Introduce you to the Jaz PX pulsed xenon light source for the Jaz modular sensing system. The Jaz-PX has a specified pulse afrequency of 200 Hz (maximum 500 Hz), spectral response from 190-1100 nm, and is ideal for UV-VIS applications such as absorbance, bioreflectance, fluorescence and phosphorescence. We will walk you through the basics of running the PX in various modes, and will perform a basic reflection measurement using SpectraSuite Software.

While Astronaut Jim is cleaning the Rover and TV camera, Joe at Houston makes a Joke, asking Astronaut Jim to clean the 'Lamp' Light Source that is pretending to be the Sun. Jim says Jokingly to turn the camera upwards so Houston can watch him clean the Large Lamp Light that is high up in the Ceiling of the Fake Moon-Set Studio Bay. Joe at Houston says at :03 "And could you dust our Lamp while your there please."(Astronaut Dave is heard laughing) Astronaut Jim says at :09 "Yep, stand by". Astronaut Jim says at :23 "Your cleaned up, thew." Joe at Houston says at :27 "Clean the top of the camera first please". Jim replies "Ah ok". Joe at Houston replies "Ah thats beautiful, oh magnificent, that even made us blush down here." Astronaut Jim says at :47 "Ok the tops clean, if you'll point up a little bit I'll ah,.......Clean your Lamp." Joe at Houston says at 1:17 "Could you check the oil too please".(As Astronaut Jim walks away laughing) This video as you hear it, is located for download at NASA site: ******* Apollo 15 Video Library Working below the Rover in the Station 6 crater.

Inside every plant cell, a cytoskeleton provides an interior scaffolding to direct construction of the cell’s walls, and thus the growth of the organism as a whole. Environmental and hormonal signals that modulate cell growth cause reorganization of this scaffolding. New research led by Carnegie’s David Ehrhardt provides surprising evidence as to how this reorganization process works, with important evidence as to how the direction of a light source influences a plant’s growth pattern.

At the Babaoshan Revolutionary Cemetery in Beijing, mysterious Light Circles were captured by photographers on November 12th, 2009, at memorial ceremony in memory of Mr. Zhao Jinxiang, who originated the Chinese Soaring Crane Qigong. Observing these photos with the Light Circles shot in the daytime, there are some distinguished features of these Light Circles. They can be captured against different backgrounds, in different directions, and across different time. Their sizes seem variable according to the different view of photo shoots. The edge of the Light Circles is clear and distinct. Objects inside look clearer, cleaner and shinier while is dimmer and darker outside. In compare with the sunlight, Buddha’s Light, auroras and laser, it is shown that the Light Circle characterizes with many scientific phenomena which is beyond the current optical theories. It is inferred that the mysterious Light Circle is a kind of new light source and new optical theory will have to be developed and applied on these new characteristics.

This "V8-Engine" has semi-realistic exterior and interior detail. It is made entirely from paper (except a motor, a battery holder, a few plastic tubes and electrical wires). No paint applied. It looks pure and elegant. Various shadows created by different light sources make the appearance more 3D.

Here's a typical example of a supposed 'UFO landing in the woods'. Its very similar to the GUARDIAN footage. Just because the two left light sources light up the woods and there's a blinking indiscriminate light, there is no reason to suggest that this is an 'outworldy' spacecraft. You wanna know what it really is? Two epicenters of a forest fire up in Dionysus mountain in Athens and a truck from the local F.D.!

Mysterious Ball Lightning Created in the Lab By Ker Than LiveScience Staff Writer posted: 23 February 2006 08:56 am ET Ball lightning is one of the most mysterious phenomena in nature. Now scientists have created a laboratory version of the eerie floating orbs using technology taken from a common microwave oven. The work could help scientists figure out how the lightning forms in nature and lead to practical applications that harness its power. In the wild, the little bundles of energy are typically only a few centimeters across, although some have been reported to be the size of beach balls or larger. They are closely associated with regular lightning and thunderstorms and have been seen in many different colors. Witnesses report hissing sounds and an acrid ozone odor when the lightning balls appear. The vivid apparitions normally hover or float around for only a few seconds before vanishing suddenly, either silently or with an explosive bang. Although people have known about ball lightning for centuries, scientists have yet to come up with an explanation that accounts for all of the strange properties. Microwave drill Eli Jerby and Vladimir Dikhtyar from the University of Tel Aviv in Israel created a laboratory version of ball lightning using a "microwave drill." The device consists of a 600-watt magnetron taken from a domestic microwave oven and uses a powerful microwave beam to bore through solid objects. The researchers aimed the beam through a pointed rod and into a solid object made from glass, silicon and other materials. The energy from the drill created a molten hot spot in the solid object; when the drill was pulled away, it dragged some of the superheated material along with it, creating a fire column [video] that then collapsed into a bright fireball that floated and bounced [video] across the ceiling of the metal enclosure. "The fireball [looked] like a hot jellyfish, quivering and buoyant in the air," Jerby said. The glowing object measured just slightly over an inch across and lasted only about 10 milliseconds. The work was detailed earlier this month in the journal Physical Review Letters. Glowing fluff balls The composition of the laboratory lightning ball still needs to be verified, but it appeared to resemble those found in nature. "Our experiment confirms to some extent the theory that ball lightning originates from hot spots in the ground created by normal lightning," Jerby told LiveScience. According to one popular theory, ball lightning forms when lightning strikes the ground and vaporizes mineral grains in the soil. The vaporized nanoparticles could then link together into chains and form a fluffy ball of silicon that floats on the wind. The particles react with oxygen in the air and release light as they burn. Jerby thinks that his laboratory lightning balls could one day find practical uses in industry. "My imagination leads me to speculate on applications like 'bulb-less' light sources, coating and deposition or energy production," he said.
