Sigma baryon

The Sigma baryons are a family of subatomic hadron particles which have a +2, +1 or −1 elementary charge or are neutral. They are baryons containing three quarks: two up and/or down quarks, and one third quark, which can be either a strange (symbols Σ+, Σ0, Σ−), a charm (symbols Σ++
c, Σ+
c, Σ0
c), a bottom (symbols Σ+
b, Σ0
b, Σ−
b) or a top (symbols Σ++
t, Σ+
t, Σ0
t) quark. However, the top Sigmas are not expected to be observed as the Standard Model predicts the mean lifetime of top quarks to be roughly 6975500000000000000♠5×10⁻²⁵ s. This is about 20 times shorter than the timescale for strong interactions, and therefore it does not form hadrons.

List

The symbols encountered in these lists are: I (isospin), J (total angular momentum), P (parity), u (up quark), d (down quark), s (strange quark), c (charm quark), t (top quark), b (bottom quark), Q (charge), B (baryon number), S (strangeness), C (charmness), B′ (bottomness), T (topness), as well as other subatomic particles (hover for name).

Phil Fearon

Phil Fearon (born 30 July 1956) is an English record producer. He was the lead singer, songwriter and multi-instrumentalist for the 1980s band Galaxy.

Career

Fearon was born in Jamaica in 1956, but moved to London with his parents at the age of five. After running a reggae sound system, he joined Hott Wax (which evolved into Brit funk pioneers Hi-Tension after he left) and in the late 1970s was a mainstay of hit group Kandidate which scored a number 11 chart hit in 1979 with "I Don't Wanna Lose You". He set up a studio in his north London house and initially recorded with the group Proton on Champagne Records. Fearon’s first recording as Galaxy (with assistance from singers Julie and Dorothy) was "Head Over Heels" on Ensign Records in 1982, which became a club hit. The first success came with the Top 5 hit "Dancing Tight" in 1983 and over the next 15 months they chalked up a further four UK Top 40 singles including the Top 10s "What Do I Do" and "Everybody’s Laughing". Their radio-friendly pop/soul debut album, Phil Fearon & Galaxy also made the Top 10 in 1984. After a quiet period, Fearon returned to the Top 10 for the last time with a revival of Tony Etoria’s "I Can Prove It" in 1986 (also a minor US R&B hit). He continued to run a production company from his home making commercial dance records.

Galaxy (spacecraft)

Galaxy (previously Guardian) is a canceled prototype space habitat designed by the American firm Bigelow Aerospace, and was intended to be the third spacecraft launched by the company in their efforts to create a commercial space station. Like other modules made by Bigelow Aerospace, Galaxy is based on the inflatable TransHab design by NASA, and was to be used for advanced systems testing before the company launched human-rated vehicles.

Spacecraft history

Galaxy started life as twin spacecraft named Guardian which would have acted as 45% scale intermediates between the one-third size Genesis I & Genesis II pathfinders and the full size BA 330 man-rated module. Sometime after 2004, the two Guardian flights were split into the Galaxy module and larger Sundancer module, each testing progressively advanced systems. This Galaxy had twice the interior volume of the Genesis craft: 23.0 cubic meters (812.2 cu ft). In 2007, the parameters for Galaxy were again modified, with final specifications being for a spacecraft 4.0 meters (13.1 ft) in length, 3.3 meters (10.8 ft) in diameter and with 16.7 cubic meters (589.8 cu ft) of interior volume—45% greater than the Genesis modules. It was intended for launch in late 2008.

Six Flags Magic Mountain

Six Flags Magic Mountain is a 262-acre (1.06 km²) theme park located in the Valencia neighborhood of Santa Clarita, California, north of Los Angeles. It opened on May 30, 1971, as Magic Mountain, a development of the Newhall Land and Farming Company. In 1979, Six Flags purchased the park and added the name "Six Flags" to the park's title.

With 19 roller coasters, Six Flags Magic Mountain holds the world record for most roller coasters in an amusement park. In 2013, the park had an estimated 2.9 million visitors ranking it fifth in attendance among seasonal amusement parks in North America.

History

When the park opened, there were 500 employees and 33 attractions, many of which were designed and built by Arrow Development Co. which designed and built many of the original attractions at Disneyland. The admission price in 1971 was $5 for adults, and $3.50 for children between the ages of 3 and 12. Because the park was in a relatively remote part of Los Angeles County, the Greyhound bus line provided bus service to and from the park and Los Angeles, as well as from Northern California, and optionally allowed purchase of park admission at the time the bus ticket is purchased.
