... Empirical and theoretical modeling of 3-D structures in the solar corona is confronted by the tremendous amount of data needed to represent phenomena with a large dynamic range both in size and magnitude, and with a rapid temporal evolution. Octree representation of the 3-D coronal electron distribution offers the right compromise between resolution and size, allowing computation of synthetic images of the solar corona. ... The time interval between images is one day. ...
... Archives . ... Going back to vlk?s comment, it is ?statistically probable? (and so natural) to see 1 keV photons in T= 10^7 K Thermal Bremsstrahlung (TB) spectra, actually more often than you might expect. ... Please, meet Ms. electron. ... Here you call it electron?s rest energy. Yeah, as if electrons rest in one place ever.б Who remembers the electron mass is 9.1e-31 kg? Well, some freaks do.б But almost all keV junkies know the electron mass is 511 keV. ... Chandra Blog . ...
... The ionospheric plasma is composed of electrons and ions, freed from each other by ultraviolet energy from the sun. ... The spectrum below shows the widths associated with the hydrogen ions and the oxygen ions, assuming that they have the same temperatures. ... In the black and gray spectrum below, the oxygen ion and electron temperatures are the same. ... temperatures: electron, oxygen ion, and hydrogen ion . ion content: oxygen, helium, and hydrogen . velocities: oxygen ion and hydrogen ion. ...

Astronotes Armagh Planetarium's Stellar Blog! ... Space Flight . ... This fluffy pink blob is the star-forming region LHA-120-N 11 in the Large Magellanic Cloud some 170 000 light years from the Sun. N 11 (occasionally called the Bean Nebula) is about 1000 light years across. ... Hydrogen is the main element making up such clouds. ... There is a certain amount of energy associated with the electron?s orbit and there are a series of possible orbits the electron can be in around the nucleus. ...
... Путь книги от бумажных страниц до файлов на этом сайте можно по сути разделить на несколько этапов. ... Начальный этап, и наиболее приемлемый вариант - сканированные страницы книги в формате TIFF или PCX (а точнее в любом формате, без ощутимой на вид компрессии. ... Относитесь к книгам с уважением. Страницы именуйте цыфрами, но всегда с сохранением числа знаков, например страница номер 7 будет иметь имя 007.tif, страница 12 будет иметь имя 012.tif, ну а страница 375 будет иметь имя 375.tif. ...

It is difficult to do experiments with K?12 students which demonstrate that light involves electric and magnetic fields. ... For advanced students, these experiments can show how light reveals the structure of atoms. ... Visible light penetrates glass. ... Static, unchanging magnetic fields don't spawn electric fields, and steady electric fields don't create magnetic fields. ... Light and other forms of electromagnetic radiation contain both electric and magnetic fields that oscillate in strength. ...
... Fermi catches thunderstorms hurling antimatter into space . Scientists think the antimatter particles formed in a terrestrial gamma-ray flash, a brief burst produced inside thunderstorms and associated with lightning. ... Scientists using NASA's Fermi Gamma-ray Space Telescope have detected beams of antimatter produced above thunderstorms on Earth, a phenomenon never seen before. ... The distant storm was below Fermi's horizon, so any gamma rays it produced could not have been detected. ...
... Almost all DSOs require a telescope to see in any detail at all, though some can be detected with just binoculars, and a few can be barely seen with the unaided eye. ... DEGREE: Distances on the sky (sometimes called the celestial sphere) are measured in angular degrees rather than inches or feet. ... The magnification is the focal length of the telescope divided by the focal length of the eyepiece. ... Short focal length eyepieces are also termed high power, long focal length are low power. ...
... The spectrum of the brightest star, our Sun, shows several dark gaps perpendicular to the flow of it’s colours (figure 1). These so called spectral absorption lines where discovered in 1802 by the English scientist William Wollaston. ... Some stars as Pollux show a spectrum similar to that of our sun with strong Ca II and Fe II lines, others as Sirius or Vega show strong absorption lines of hydrogen, others, as Mira show very complicated spectra due to molecular absorption lines (see figure 5). ...
... ARC 3.5m | ... 2.1 Choosing and Exposure Time . 2.2 Choosing the CCD Gain . ... 3.2 Read Times and Read Noise . ... At the slow read rate of 100 KHz to be used for exposure times longer than a few seconds, we determine an average read noise of order 3.7 ? ... Table 2: Exposure time must be greater than the readout time by at least 0.03 s. The Agile CCD camera has two readout amplifiers, one of which is capable of reading at the fast readrate of 1MHz while introducing a read noise of order 7 ? ...
P.O. Box 797 Sonoita, AZ 85637-0797 June 19, 2000 Prof. David Chalmers Philosophy Department Room 213, Social Sciences Building University of Arizona Tucson, AZ 85721-0027 Dear Prof. Chalmers: Well, here's another one from Mr. At-Least-I-Thought-Of-It-Independently. ... So as a thought experiment, let's imagine that instead of having our matter transporter actually move matter, what it moves is information. ... That will make it necessary to move the matter to move consciousness. ...
