Tom Hanks Now Getting Serious For ‘Saving Mr. Banks’ (Deadline Hollywood)
**EXCLUSIVE**: Deadline told you back in February that Tom Hanks was in the
mix to play Walt Disney in the Lee Hancock directed __, the Kelly Marcel-
scripted saga of how Walt Disney waged a 14-year courtship to persuade
Australian author P.L. Travers to sell him rights to make a film out of Mary
Poppins. Now, things are heating up with Hanks to potentially star with Emma
Thompson (Meryl Streep was also being courted) for Disney, which in February
made a deal to acquire the Black List script, which is set up with producer
Alison Owen of Ruby Films. Disney seems a natural place for the script,
considering the studio owns many rights from making the 1964 classic film that
starred Julie Andrews, Dick Van Dyke and David Tomlinson, the latter of whom
played Mr. Banks in the film. The heart of this script comes from how close
Travers felt to her story of a nanny with magical powers. Mary Poppins was
highly personal, and reflected hardships in her own life and her relationship
with her father, who died when she was 7. Disney finally persuaded her to let
him make the film, but ...
Is natural ruby gemstone used in spaceships?
if yes, why? in which respect? for what qualities?
No, not even Russians use natural ruby gemstone for their the spaceships/rockets.
Natural ruby is a red gemstone, a variety of the mineral corundum (aluminium oxide), but only industry which uses it in the natural form -- is jewellery, because synthetic corundum (ruby) is easy to produce and it cost a lot cheaper. A synthetic ruby crystal was used to create the first laser. Ruby laser can be used for surveying and ranging. For example, pulsed ruby laser was used to measure the distance between Earth and Moon by Apollo 11 and Apollo 14 astronauts who put corner reflectors on the surface of the Moon
Generally, synthetic corundum (ruby) used for:
1. Lasers
Ruby is an aluminum oxide crystal in which some of the aluminum atoms have been replaced with chromium atoms. Chromium gives ruby its characteristic red color and is responsible for the lasing behavior of the crystal. Chromium atoms absorb green and blue light and emit or reflect only red light. For a ruby laser, a crystal of ruby is formed into a cylinder. A fully reflecting mirror is placed on one end and a partially reflecting mirror on the other. A high-intensity lamp is spiraled around the ruby cylinder to provide a flash of white light that triggers the laser action. The green and blue wavelengths in the flash excite electrons in the chromium atoms to a higher energy level. Upon returning to their normal state, the electrons emit their characteristic ruby-red light. The mirrors reflect some of this light back and forth inside the ruby crystal, stimulating other excited chromium atoms to produce more red light, until the light pulse builds up to high power and drains the energy stored in the crystal.
2. Abrasives
Corundum having a bright and glassy lustre, splintery and devoid of cleavage plane and inclusions is preferred by industry for the manufacture of superior grade abrasives. The corundum is crushed, ground and screened to grain sizes varying from 100 to 300 mesh. The grains are utilized in the manufacture of grinding wheels for flour and rice mills, and workshops.
3. Other uses
Corundum in small quantities is used in the manufacture of special sparking plugs, muffles, pyrometer tubes, rod and insulator for vacuum tubes of all kinds and crucibles. Finely ground corundum, passing through 200 mesh, the alumina content not below 90%, is used for the manufacture of the above products by giving a bond of clay.
