Input: Question: How old was the man that proposed a "tired light" mechanism? Passage 1:At the same time, other explanations were proposed that did not concord with general relativity. Edward Milne proposed an explanation compatible with special relativity but not general relativity that there was a giant explosion that could explain redshifts (see Milne universe). Others proposed that systematic effects could explain the redshift-distance correlation. Along this line, Fritz Zwicky proposed a "tired light" mechanism in 1929. Zwicky suggested that photons might slowly lose energy as they travel vast distances through a static universe by interaction with matter or other photons, or by some novel physical mechanism. Since a decrease in energy corresponds to an increase in light's wavelength, this effect would produce a redshift in spectral lines that increase proportionally with the distance of the source. The term "tired light" was coined by Richard Tolman in the early 1930s as a way to refer to this idea.
 Passage 2:In 1843, Barnett was elected (by the Georgia State Senate) to the position of Georgia Secretary of State, a position he held for three terms until 1849. He was subsequently elected to another, single, term in 1851. He was again elected to the position for the period 1861-1868, but was removed by the Military Governor at the onset of the Reconstruction era. It is said that Barnett twice saved the Great Seal of the State of Georgia. The first time was when Union troops under William Tecumseh Sherman were about to capture the State Capitol at Milledgeville. Barnett took the seal, and numerous official documents and Acts, and with the assistance of his wife Mary, buried them at his farm. After Sherman's troops marched on, Barnett returned the seal and the documents to the state. In 1866 Barnett again removed the Great Seal from the capitol. General Ruger, who was at that time acting as the Military Governor of Georgia, requested that Barnett affix the seal to an executive act, which Colonel Barnett could not approve. He refused to sanction the papers with the imprint of the seal and as a consequence was removed by General Ruger. Colonel Barnett then took the seal with him to prevent it from falling into the hands of what was considered an illegitimate Carpetbagger government which occupied the state: so that it was never affixed to any of the documents of misrule which followed under the carpetbag government. Since the seal was required, to certify official acts of the state government, the Reconstruction government fabricated a replacement. That replacement was identical in all respects except one. The soldier depicted on the replacement seal held his sword in the wrong hand. The period of the Reconstruction government in Georgia is thus referred to as the "Period of the False Seal". The Great Seal and documents were buried on Barnett's farm, and remained hidden there until 1868, when a new state constitution was enacted and a new government installed. After democrats regained control of state government, Barnett was again elected Secretary of State in 1873. Upon his return to office, both houses of the Legislature voted to present him with a replica of the Executive Seal, which replica is now in Savannah, Georgia, the property of the Georgia Historical Society. Barnett continued to serve as Secretary of State until his death on 2 February 1890. Toward the end of his more than 30 years of service as secretary of state under numerous administrations and into his late 80s, he was said to wear a row of three pairs of glasses. A portrait of Barnett hangs in the office of the Georgia Secretary of State to this day.
 Passage 3:"Kitty Kat" received generally favorable reviews from critics. Eb Haynes of AllHipHop described "Kitty Kat" as a seductive track. Norman Mayers of Prefix Magazine wrote that B'Day is packed with standouts such as "the Rich Harrison-produced 'Freakum Dress' and the Neptunes-helmed 'Kitty Kat'." Picking out "Kitty Kat" as one of the four top tracks of the album, Spence D of IGN Music added that the song slows things down, allowing for Knowles' "crystal clear vocals to take some down time and relinquish up a dreamy, creamy sound that is playfully sensuous." Andy Kellman of Allmusic described "Kitty Kat" as "a deceptively sweet, rainbow-colored track" where purrs - that are sound made by all species of felids and are a part of cat communication - are more like "claws-out dismissals." Jon Pareles of The New York Times called the song a "cooing [and] sighing" one. Sal Cinquemani of Slant Magazine noted that "Kitty Kat" was "the only mid-tempo break" until the very end of the album. Darryl Sterdan, writing for the Canadian website Jam!, said that the song is just about what you think. Thomas Inskeep of Stylus Magazine commented that "Kitty Kat" seems to be an obvious tracks produced by The Neptunes. He went on complimenting "the squishy R&B keyboard which works well with the song’s 'I’m not feelin[g] it' vibe." A writer of the Seattle Post-Intelligencer commented, "Beyoncé is better at being sexy than sarcastic, and 'Kitty Kat' doesn't make any bones about what her absentee lover is missing." Michael Roberts of New Times Broward-Palm Beach commented that Knowles "purrs at lower speed" in the song.
