World (Bee Gees song)

"World" is a song from the Bee Gees' fourth album Horizontal, released in 1967 in the United Kingdom. Though it was a big hit in Europe, Atco Records did not issue it as a single in the United States, having just issued a third single from Bee Gees' 1st, "Holiday".

Composition

The song's lyrics question the singer's purpose in life.

Recording

The song's first recording session was on 3 October 1967 along with "With the Sun in My Eyes" and "Words". The song's last recording session was on 28 October 1967. "World" was originally planned as having no orchestra, so all four tracks were filled with the band, including some mellotron or organ played by Robin. When it was decided to add an orchestra, the four tracks containing the band were mixed to one track and the orchestra was added to the other track. The stereo mix suffered since the second tape had to play as mono until the end when the orchestra comes in on one side. Barry adds: "'World' is one of those things we came up with in the studio, Everyone just having fun and saying, 'Let's just do something!' you know". Vince Melouney recalls: "I had this idea to play the melody right up in the top register of the guitar behind the chorus".

World (Five for Fighting song)

"World" is a song written and recorded by American recording artist Five for Fighting. It was released in November 2006 as the second single from the album Two Lights. It reached number 14 on the U.S. Billboard Adult Pop Songs chart.

Content

"World" is an upbeat, piano-driven melody that, like his other singles, paints vivid pictures of human life driven with deep emotion. The song's lyrics are notably more cryptic than in previous singles, but are driven by the chorus hooks, "What kind of world do you want?" and "Be careful what you wish for, history starts now."

Critical reception

Chuck Taylor, of Billboard magazine reviewed the song favorably, calling the song "admittedly more abstract" but the average listener will pick out certain lines and find a relatable message. He goes on to say that "alongside, the piano-driven, orchestrated melody is his most captivating yet lush and instantly memorable."

Music video

The music video for "World" features aspects of the bright side of life including children, marriage and fireworks. There are also references that go with the lyrics including a brief image of a mushroom cloud in a cup of coffee, with a newspaper's headline featuring North Korea's nuclear program. It was directed by Todd Strauss-Schulson.

1977 World 600

The 1977 World 600, the 18th running of the event, was a NASCAR Winston Cup Series racing event that took place on May 29, 1977, at Charlotte Motor Speedway in Concord, North Carolina.

Jim Stacy would become the owner of Krauskopf's old NASCAR team after this event; with the famed red #71 Dodge getting repainted into the white #5. Neil Bonnett, however, would stay on the team as a driver. By 1980, NASCAR had completely stopped tracking the year model of all the vehicles and most teams did not take stock cars to the track under their own power anymore.

Summary

Forty American-born drivers competed here including Benny Parsons, Lennie Pond, Buddy Baker, Darrell Waltrip, and Neil Bonnett. After four hours and twenty-one minutes of racing action, Richard Petty defeated polesitter David Pearson by 30.8 seconds in front of an audience of 115000 people. There were 25 lead changes done in this race in addition to six cautions for 31 laps. While the qualifying top speed was 161.435 miles per hour (259.804 km/h), the average speed of the race was actually 136.676 miles per hour (219.959 km/h). Last-place finisher Ramo Stott would acquire engine trouble on lap 3 of the 400-lap race. The duration of the race was from 12:30 P.M. to 4:41 P.M.; allowing fans to drive to nearby restaurants for supper.

Helix

A helix (pl: helixes or helices) is a type of smooth space curve, i.e. a curve in three-dimensional space. It has the property that the tangent line at any point makes a constant angle with a fixed line called the axis. Examples of helices are coil springs and the handrails of spiral staircases. A "filled-in" helix – for example, a spiral ramp – is called a helicoid. Helices are important in biology, as the DNA molecule is formed as two intertwined helices, and many proteins have helical substructures, known as alpha helices. The word helix comes from the Greek word ἕλιξ, "twisted, curved".

Types

Helices can be either right-handed or left-handed. With the line of sight along the helix's axis, if a clockwise screwing motion moves the helix away from the observer, then it is called a right-handed helix; if towards the observer, then it is a left-handed helix. Handedness (or chirality) is a property of the helix, not of the perspective: a right-handed helix cannot be turned to look like a left-handed one unless it is viewed in a mirror, and vice versa.

Phelix

Phelix is a high-speed stream cipher with a built-in single-pass message authentication code (MAC) functionality, submitted in 2004 to the eSTREAM contest by Doug Whiting, Bruce Schneier, Stefan Lucks, and Frédéric Muller. The cipher uses only the operations of addition modulo 2³², exclusive or, and rotation by a fixed number of bits. Phelix uses a 256-bit key and a 128-bit nonce, claiming a design strength of 128 bits. Concerns have been raised over the ability to recover the secret key if the cipher is used incorrectly.

Performance

Phelix is optimised for 32-bit platforms. The authors state that it can achieve up to eight cycles per byte on modern x86-based processors.

FPGA Hardware performance figures published in the paper "Review of stream cipher candidates from a low resource hardware perspective" are as follows:

Helix

Phelix is a slightly modified form of an earlier cipher, Helix, published in 2003 by Niels Ferguson, Doug Whiting, Bruce Schneier, John Kelsey, Stefan Lucks, and Tadayoshi Kohno; Phelix adds 128 bits to the internal state.

Pi helix

A pi helix (or π-helix) is a type of secondary structure found in proteins. Although once thought to be rare, short π-helices are found in 15% of known protein structures and are believed to be an evolutionary adaptation derived by the insertion of a single amino acid into an α-helix. Because such insertions are highly destabilizing, the formation of π-helices would tend to be selected against unless it provided some functional advantage to the protein. π-helices therefore are typically found near functional sites of proteins.

Standard structure

The amino acids in a standard π-helix are arranged in a right-handed helical structure. Each amino acid corresponds to an 87° turn in the helix (i.e., the helix has 4.1 residues per turn), and a translation of 1.15 Å (=0.115 nm) along the helical axis. Most importantly, the N-H group of an amino acid forms a hydrogen bond with the C=O group of the amino acid five residues earlier; this repeated i+5→i hydrogen bonding defines a π-helix. Similar structures include the 3₁₀ helix (i+3→i hydrogen bonding) and the α-helix (i+4→i hydrogen bonding).
