Please answer this: This article: To promote No Line on the Horizon, U2 performed "Get on Your Boots" at the 51st Grammy Awards, the 2009 BRIT Awards, and the 2009 Echo Awards, although the album was not eligible for awards at any of the ceremonies. The band later appeared on French television and radio on 23 February 2009, and on 26 February they taped a segment for Friday Night with Jonathan Ross, which was aired the next day. On 27 February, U2 made an appearance on a Live Lounge session for BBC Radio 1, followed by a mini-concert on the roof of Broadcasting House. On the week of 2 March 2009, U2 appeared on CBS-TV's Late Show with David Letterman for five consecutive nights, the first time a musical guest had performed for an entire week on the show. The group performed "Breathe", "Magnificent", "I'll Go Crazy If I Don't Go Crazy Tonight", "Beautiful Day", and "Get on Your Boots". On 3 March, Michael Bloomberg, Mayor of New York City, added a street sign reading "U2 Way" at 53rd Street in Manhattan, for the week that U2 performed on the Late Show. U2 also performed at Fordham University on 6 March 2009 for an appearance on ABC-TV's Good Morning America. From 9 to 11 March, the band participated in "U2 3 Nights Live", a series of radio interviews and performances that were broadcast across North America and streamed live on U2.com.From 11 to 17 February 2009, U2.com hosted a promotion where 4,000 fans could win a 7-inch single collector's edition box set that contained all four of the singles released from No Line on the Horizon. An alternate version of the title track, "No Line on the Horizon 2", debuted on RTÉ 2XM on 12 February 2009; it was later used as the B-side for the first single, "Get on Your Boots". The full album began streaming on the group's MySpace page on 20 February 2009, and on U2.com a few days later.Four singles were planned from the album, although only three were released. The first single, "Get on Your Boots", was released as a digital download on 19 January 2009, and in a physical format on 16 February 2009. The... contains an answer for the question: What was later used as the B-side for the first single?, what is it ?

Please answer this: This article: 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 Segrè, and he was swayed by Segrè's authority over that of a more junior [but unnamed] member of Segrè'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. Segré brought in Jack Aeby's 35 mm... contains an answer for the question: What type of camera took the only known well-exposed color photograph of the detonation explosion?, what is it ?

Please answer this: This article: In recent years, several other craters of around the same age as Chicxulub have been discovered, all between latitudes 20°N and 70°N. Examples include the disputed Silverpit crater in the North Sea, and the Boltysh crater in Ukraine. Both are much smaller than Chicxulub, but are likely to have been caused by objects many tens of meters across striking the Earth. This has led to the hypothesis that the Chicxulub impact may have been only one of several impacts that happened nearly at the same time. Another possible crater thought to have been formed at the same time is the larger Shiva crater, though the structure's status as an impact crater is contested.The collision of Comet Shoemaker–Levy 9 with Jupiter in 1994 demonstrated that gravitational interactions can fragment a comet, giving rise to many impacts over a period of a few days if the comet should collide with a planet. Comets undergo gravitational interactions with the gas giants, and similar disruptions and collisions are very likely to have occurred in the past. This scenario may have occurred on Earth at the end of the Cretaceous, though Shiva and the Chicxulub craters might have been formed 300,000 years apart.In late 2006, Ken MacLeod, a geology professor from the University of Missouri, completed an analysis of sediment below the ocean's surface, bolstering the single-impact theory. MacLeod conducted his analysis approximately 4,500 kilometres (2,800 mi) from the Chicxulub crater to control for possible changes in soil composition at the impact site, while still close enough to be affected by the impact. The analysis revealed there was only one layer of impact debris in the sediment, which indicated there was only one impact. Multiple-impact proponents such as Gerta Keller regard the results as "rather hyper-inflated" and do not agree with the conclusion of MacLeod's analysis, arguing that there might only be gaps of hours to days between impacts in a multiple-impact scenario (cf. Shoemaker-Levy 9) which would not leave a detectable gap in deposits. contains an answer for the question: What was the full name of the person whose analysis revealed there was only one layer of impact debris in the sediment?, what is it ?
