Problem: Addition of lead(II) oxide lowers melting point, lowers viscosity of the melt, and increases refractive index. Lead oxide also facilitates solubility of other metal oxides and is used in colored glasses. The viscosity decrease of lead glass melt is very significant (roughly 100 times in comparison with soda glasses); this allows easier removal of bubbles and working at lower temperatures, hence its frequent use as an additive in vitreous enamels and glass solders. The high ionic radius of the Pb2+ ion renders it highly immobile in the matrix and hinders the movement of other ions; lead glasses therefore have high electrical resistance, about two orders of magnitude higher than soda-lime glass (108.5 vs 106.5 Ohm·cm, DC at 250 °C). For more details, see lead glass.
Lead oxide makes it easier to dissolve what?

Answer: other metal oxides


Problem: Local anesthetic injections into the nerves or sensitive areas of the stump may relieve pain for days, weeks, or sometimes permanently, despite the drug wearing off in a matter of hours; and small injections of hypertonic saline into the soft tissue between vertebrae produces local pain that radiates into the phantom limb for ten minutes or so and may be followed by hours, weeks or even longer of partial or total relief from phantom pain. Vigorous vibration or electrical stimulation of the stump, or current from electrodes surgically implanted onto the spinal cord, all produce relief in some patients.
What does vigorous stimulation provide?

Problem: Satyagraha, an opera by Philip Glass, uses texts from the Bhagavad Gita, sung in Sanskrit. The closing credits of The Matrix Revolutions has a prayer from the Brihadaranyaka Upanishad. The song "Cyber-raga" from Madonna's album Music includes Sanskrit chants, and Shanti/Ashtangi from her 1998 album Ray of Light, which won a Grammy, is the ashtanga vinyasa yoga chant. The lyrics include the mantra Om shanti. Composer John Williams featured choirs singing in Sanskrit for Indiana Jones and the Temple of Doom and in Star Wars: Episode I – The Phantom Menace. The theme song of Battlestar Galactica 2004 is the Gayatri Mantra, taken from the Rigveda. The lyrics of "The Child In Us" by Enigma also contains Sanskrit verses.[better source needed].
