input: While Rancid was writing for a follow-up album, Billie Joe Armstrong joined them to co-write the song "Radio", which resulted in Armstrong playing a live performance with Rancid. Tim had previously asked Lars Frederiksen to be Rancid's second guitarist, but he turned down the request initially as he was playing with the UK Subs at the time. After Billie Joe turned down the request, Frederiksen changed his mind and joined Rancid.  Frederiksen played with the band on its second studio album Let's Go (1994). That year, its then-label-mates, The Offspring, experienced huge success with its album Smash. Rancid supported the Offspring's 1994 tour, which helped Let's Go reach number 97 on Billboard's Heatseekers and the Billboard 200 charts, respectively. The album also provided its first widespread exposure when MTV broadcast the video for the single "Salvation." Let's Go was certified gold on July 7, 2000, and with the success of the album, the band was pursued by a number of major record labels, including Madonna's label Maverick Records. Many rumors circulated during this time period. Some of the rumors were Epitaph employees were not allowed to discuss matters with the press, Rancid convinced an A&R man from Epic to shave a blue mohawk, and Madonna sent the band nude pictures of herself.  The band eventually decided to remain signed to Epitaph, and the next year released its third album ...And Out Come the Wolves on August 22, 1995. The album quickly surpassed Let's Go in terms of success, and reached number 45 on the Billboard 200 album chart. on January 22, 1996, the album was certified gold. The album received positive reviews, Stephen Thomas Erlewine of AllMusic described the album as having "classic moments of revivalist punk". Erlewine praised the music and claims the album "doesn't mark an isolationist retreat into didactic, defiantly underground punk rock". Three of the album's singles, "Roots Radicals", "Time Bomb", and "Ruby Soho" all charted on the Billboard Modern Rock Tracks, and earned Rancid its heaviest airplay on MTV and radio stations to date. The band also performed "Roots Radicals" and "Ruby Soho" on Saturday Night Live.

output: write the song "Radio", which resulted in Armstrong playing a live performance with Rancid.

input: Lewontin has worked in both theoretical and experimental population genetics. A hallmark of his work has been an interest in new technology. He was the first person to do a computer simulation of the behavior of a single gene locus (previous simulation work having been of models with multiple loci). In 1960 he and Ken-Ichi Kojima were the first population geneticists to give the equations for change of haplotype frequencies with interacting natural selection at two loci. This set off a wave of theoretical work on two-locus selection in the 1960s and 1970s. Their paper gave a theoretical derivation of the equilibria expected, and also investigated the dynamics of the model by computer iteration. Lewontin later introduced the D' measure of linkage disequilibrium. (He also introduced the term "linkage disequilibrium", about which many population geneticists have been unenthusiastic.)  In 1966, he and Jack Hubby published a paper that revolutionized population genetics. They used protein gel electrophoresis to survey dozens of loci in the fruit fly Drosophila pseudoobscura, and reported that a large fraction of the loci were polymorphic, and that at the average locus there was about a 15% chance that the individual was heterozygous. (Harry Harris reported similar results for humans at about the same time.) Previous work with gel electrophoresis had been reports of variation in single loci and did not give any sense of how common variation was.  Lewontin and Hubby's paper also discussed the possible explanation of the high levels of variability by either balancing selection or neutral mutation. Although they did not commit themselves to advocating neutrality, this was the first clear statement of the neutral theory for levels of variability within species. Lewontin and Hubby's paper had great impact--the discovery of high levels of molecular variability gave population geneticists ample material to work on, and gave them access to variation at single loci. The possible theoretical explanations of this rampant polymorphism became the focus of most population genetics work thereafter. Martin Kreitman was later to do a pioneering survey of population-level variability in DNA sequences while a Ph.D. student in Lewontin's lab.

input: In 1762, Peale married Rachel Brewer (1744-1790), who bore him ten children, most named for Peale's favorite artists, male and female. The sons included Raphaelle Peale (1774-1825), Rembrandt Peale (1778-1860), who was another famous portrait painter and museum owner/operator in Baltimore, and scientific inventor and businessman, Titian Peale I (1780-1798), and Rubens Peale (1784-1865). Among the daughters: Angelica Kauffman Peale (named for Angelica Kauffman, Peale's favorite female painter) married Alexander Robinson, her daughter Priscilla Peale wed Dr. Henry Boteler, and Sophonisba Angusciola Peale (named for Sofonisba Anguissola) married Coleman Sellers.  After Rachel's death in 1790, Peale married Elizabeth de Peyster (d. 1804) the next year. With his second wife, he had six additional children. One son, Franklin Peale, born on October 15, 1795, became the Chief Coiner at the Philadelphia Mint. Their youngest son, Titian Ramsay Peale (1799-1885), became an important naturalist and pioneer in photography. Their daughter, Elizabeth De Peyster Peale (1802-57), married William Augustus Patterson (1792-1833) in 1820.  Hannah More, a Quaker from Philadelphia, married Peale in 1804, becoming his third wife. She helped raise the younger children from his previous two marriages.  Peale's slave, Moses Williams, was also trained in the arts while growing up in the Peale household and later became a professional silhouette artist.  In 1810, Peale purchased a farm in Germantown where he intended to retire. He named this estate 'Belfield', and cultivated extensive gardens there. After Hannah's death in 1821, Peale lived with his son Rubens and sold Belfield in 1826. Peale died on February 22, 1827, and was buried at the Saint Peter's Episcopal Church in Philadelphia.
