Vibration

Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. The word comes from Latin vibrationem ("shaking, brandishing") The oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.

Vibration can be desirable: for example, the motion of a tuning fork, the reed in a woodwind instrument or harmonica, a mobile phone, or the cone of a loudspeaker.

In many cases, however, vibration is undesirable, wasting energy and creating unwanted sound. For example, the vibrational motions of engines, electric motors, or any mechanical device in operation are typically unwanted. Such vibrations could be caused by imbalances in the rotating parts, uneven friction, or the meshing of gear teeth. Careful designs usually minimize unwanted vibrations.

The studies of sound and vibration are closely related. Sound, or pressure waves, are generated by vibrating structures (e.g. vocal cords); these pressure waves can also induce the vibration of structures (e.g. ear drum). Hence, attempts to reduce noise are often related to issues of vibration.

Helium (film)

Helium is an Oscar-winning 2014 short film by Danish film maker Anders Walter.

Plot

Alfred is a young boy staying in a hospital who suffers from an undisclosed terminal illness. Enzo, a janitor at the hospital, meets Alfred while working and the two develop a friendship. Enzo tells Alfred of Helium, an attractive alternative to Heaven, because Alfred imagines Heaven is very boring. Enzo tells Alfred that to get to Helium, he will fly in an airship that will know to pick him up because of his red balloon dog, which Enzo has made for him.

Alfred's illness worsens, and he is moved to a unit to which Enzo doesn’t have access. Enzo sneaks onto the unit, but is caught by the head nurse and barred from seeing Alfred. As Alfred's condition worsens, Enzo wonders if he is making it worse for the boy. He voices these concerns to a nurse saying, “I’m feeding him lies.” She disagrees and tells Enzo “you’re giving him hope.”

Alfred gets worse, and having no access to him, Enzo writes out “the end of the story” to have the nurse read to him. As the nurse is about to read the ending to a dying Alfred, she changes her mind and, instead, sneaks Enzo onto the unit to tell the rest himself.

Helium (band)

Helium was an American alternative rock band formed during the summer of 1992. Under the original moniker of "Chupa," the band's founding members were Mary Lou Lord; Jason Hatfield, Juliana Hatfield's brother; Shawn King Devlin; and Brian Dunton. Devlin and Dunton were both also in the band Dumptruck before founding Helium.

History

Mary Timony, formerly of the band Autoclave, replaced Mary Lou Lord on vocals and guitar shortly after formation, as Lord was reluctant to use electric instrumentation. Following Lord's departure, the remaining members changed the band's name to Helium.

As Helium's second frontperson, Timony incorporated a Lolita-esque image with the band, with short schoolgirl skirts, an accompanying hairstyle, and naughty lyrics. Timony was also known for her husky, vibrato-less and monotone singing style. The band's record label, Matador Records, likened Timony's vocals to Kim Wilde and Debbie Harry.

Releases

Their first release was a 7" single entitled "The American Jean" (1993), which was followed by the 7" "Hole in the Ground". They released their first EP, Pirate Prude, in 1994. Shortly after the release of Pirate Prude, Dunton left the band and Polvo guitarist Ash Bowie, boyfriend of Timony at the time, joined on bass. In 1995, they released their first full-length release, The Dirt of Luck, and played the second stage of Lollapalooza. Adam Lasus produced and engineered The Dirt of Luck, Pirate Prude, and all of Helium's singles up to 1995.
