The picture above was made with this demo POV file and this Mirror object POV file . ... This is a magnifying mirror with a light around it, on an articulated arm, designed for wall-mounting. ... Behind this mirror in the image are two more mirrors, one above showing the front, and one below showing the arm in a bent position, and the whole thing roated so that you are effectively looking "up" at it. ... The two images below show details of the base, and the back of the mirror. ...

REPORT ON PIERRE DELIGNE FELLOWSHIP, 2010 SERGEY OBLEZIN During 2010 I have been working on developing a representation theory approach to mirror symmetry and quantum cohomology of homogeneous spaces, associated to Lie groups of classical type. According to Givental the glN -Whittaker functions, being solutions to the quantum cohomology D-module QH (FlN ) of the complete flag variety FlN = GLN (C)/B , describe the corresponding equivariant Gromov-Witten invariants of FlN . ...

Never in the history of exploration has there been an undertaking quite like Apollo. ... Few of the half million ever had a chance to travel in space and fewer still walked on the Moon; but most were deeply dedicated and, for them, working on Apollo was much more than a job. ... Apollo was a start. ... By the time of the last three missions, crews were spending three days on the Moon and, out of each twenty-four hours, were staying outside and working hard for six to seven hours at a time. ...

... Tiny Tim has been used for generating Hubble Space Telescope ( HST ) point-spread functions (PSFs) for deconvolution, algorithm testing, proposal planning, and optical studies. ... Tiny Tim is a stand-alone program for simulating HST PSFs as viewed with the on-board imaging cameras (WF/PC-1, WFPC2, FOC, COSTAR/FOC). ... The measured aberrations for FOC f/96, WF/PC-1 PC6, WFPC2, and COSTAR/FOC are used by Tiny Tim . ... Figure: FOC f/96 observed and Tiny Tim model PSFs (pre-COSTAR) at 253 nm. ...

An astronomer by training, I currently work at the Australia Telescope National Facility , part of the CSIRO . I am part of the computing group for the Australian Square Kilometre Array Pathfinder (ASKAP), where my job is to develop science analysis software for the ASKAP processing pipeline. The huge volumes of data that ASKAP will produce mean that all observations will be processed automatically in pipelines. ... Matthew Whiting . ... Australia . ...

Astronotes Armagh Planetarium's Stellar Blog! ... Universe . ... About four centuries ago, a tiny white dwarf star about the same diameter as Earth, but with a mass equivalent to the Sun, swung in a tight orbit about some larger star. The white dwarfтАЩs intense gravity tore material from its more massive companion. ... The quantity of mass in the universe is constant since the universe started its last self-replication, since its last singularity, its last pre-big bang re-birth conception. ...

You will need to understand how to set file access permissions numerically before reading this section. Every time you create a file or a directory, its access permissions are set to a predetermined value. ... The values in the mask are subtracted from these values to give a default value for access permissions for the files and directories created by you. For example: 777 (system value for directories) -077 (value of the umask) --- 700 (default access permission of rwx------) . ...
