Please answer this: What is the full name of the person that was the Chief Engraver after James Barton Longacre? Answer the above question based on the context below: James Barton Longacre (August 11, 1794 January 1, 1869) was an American portraitist and engraver, and the fourth Chief Engraver of the United States Mint from 1844 until his death. Longacre is best known for designing the Indian Head cent, which entered commerce in 1859, and for the designs of the Shield nickel, Flying Eagle cent and other coins of the mid-19th century. Longacre was born in Delaware County, Pennsylvania, in 1794. He ran away to Philadelphia at age 12, where he became an apprentice in a bookstore. His artistic talent developed and he was released to apprentice in an engraving firm. He struck out on his own in 1819, making a name providing illustrations for popular biographical books. He portrayed the leading men of his day; support from some of them, such as South Carolina Senator John C. Calhoun, led to his appointment as chief engraver after the death of Christian Gobrecht in 1844. In Longacre's first years as a chief engraver, the Philadelphia Mint was dominated by Mint Director Robert M. Patterson and Chief Coiner Franklin Peale. Conflict between Longacre and the two men developed after Congress ordered a new gold dollar and double eagle, with both to be designed by Longacre. Peale and Patterson nearly had Longacre fired, but the chief engraver was able to convince Treasury Secretary William M. Meredith that he should be retained. Both Patterson and Peale left the Mint in the early 1850s, ending the conflict. In 1856, Longacre designed the Flying Eagle cent. When that design proved difficult to strike, Longacre was responsible for the replacement, the Indian Head cent, issued beginning in 1859. Other coins designed by Longacre include the silver and nickel three-cent pieces, the Shield nickel, the pattern Washington nickel, and the two-cent piece. In 18661867, he redesigned the coins of Chile. Longacre died suddenly on New Year's Day 1869; he was succeeded by William Barber. Longacre's coins are generally well-regarded today, although they have been criticized for lack of artistic...

Problem: What are the full names of the three who were enrolled at Macquarie Universtiy? Answer the above question based on the context below: Anthony Field and Jeff Fatt were members of The Cockroaches, a Sydney pop band known for their "good-time R&B material" and several singles recorded by independent labels during the 1980s. In 1988, Field's infant niece, who was the daughter of Cockroaches founder and band member Paul Field, died of SIDS, and the group disbanded. Anthony Field enrolled at Macquarie University in Sydney to complete his degree in early childhood education, and later stated that his niece's death "ultimately led to the formation of [The] Wiggles". Murray Cook, also "a mature-aged student", was the guitarist in the pub rock band Bang Shang a Lang before enrolling at Macquarie. Greg Page, who had been a roadie for and sang with The Cockroaches during their final years, had enrolled in Macquarie to study early childhood education on Field's recommendation. Field, Cook, and Page were among approximately 10 men in a program with 200 students.In 1991, while still a student, Field became motivated to use concepts in the field of early childhood education to record an album of music for children. The album was dedicated to Field's niece. A song he wrote for The Cockroaches, "Get Ready to Wiggle", inspired the band's name because they thought that wiggling described the way children dance. Like a university assignment, they produced a folder of essays that explained the educational value of each song on the album. They needed a keyboardist "to bolster the rock'n'roll feel of the project", so Field asked his old bandmate Fatt for his assistance in what they thought would be a temporary project.The group received songwriting help from John Field, Anthony's brother and former bandmate, and from Phillip Wilcher, who was working with the early childhood music program at Macquarie. After contributing to their first album, hosting the group's first recording sessions in his Sydney home, and appearing in a couple of the group's first videos, Wilcher left the group and went into classical music. The group reworked a few Cockroaches tunes...

Q: What type of camera took the only known well-exposed color photograph of the detonation explosion? Answer the above question based on the context below: Others were less optimistic. Ramsey chose zero (a complete dud), Robert Oppenheimer chose 0.3 kilotons of TNT (1.3 TJ), Kistiakowsky 1.4 kilotons of TNT (5.9 TJ), and Bethe chose 8 kilotons of TNT (33 TJ). Rabi, the last to arrive, took 18 kilotons of TNT (75 TJ) by default, which would win him the pool. In a video interview, Bethe stated that his choice of 8 kt was exactly the value calculated by Segre, and he was swayed by Segre's authority over that of a more junior [but unnamed] member of Segre's group who had calculated 20 kt. Enrico Fermi offered to take wagers among the top physicists and military present on whether the atmosphere would ignite, and if so whether it would destroy just the state, or incinerate the entire planet. This last result had been previously calculated by Bethe to be almost impossible, although for a while it had caused some of the scientists some anxiety. Bainbridge was furious with Fermi for scaring the guards who, unlike the physicists, did not have the advantage of their knowledge about the scientific possibilities. His own biggest fear was that nothing would happen, in which case he would have to head back to the tower to investigate.Julian Mack and Berlyn Brixner were responsible for photography. The photography group employed some fifty different cameras, taking motion and still photographs. Special Fastax cameras taking 10,000 frames per second would record the minute details of the explosion. Spectrograph cameras would record the wavelengths of light emitted by the explosion, and pinhole cameras would record gamma rays. A rotating drum spectrograph at the 10,000-yard (9,100 m) station would obtain the spectrum over the first hundredth of a second. Another, slow recording one would track the fireball. Cameras were placed in bunkers only 800 yards (730 m) from the tower, protected by steel and lead glass, and mounted on sleds so they could be towed out by the lead-lined tank. Some observers brought their own cameras despite the security. Segre brought in Jack Aeby's 35 mm...
