HVAC is based on inventions and discoveries made by Nikolay Lvov, Michael Faraday, Willis Carrier, Edwin Ruud, Reuben Trane, James Joule, William Rankine, Sadi Carnot, and many others.
Multiple inventions within this time frame preceded the beginnings of first comfort air conditioning system, which was designed in 1902 by Alfred Wolff (Cooper, 2003) for the New York Stock Exchange, while Willis Carrier equipped the Sacketts-Wilhems Printing Company with the process AC unit the same year.
The invention of the components of HVAC systems went hand-in-hand with the industrial revolution, and new methods of modernization, higher efficiency, and system control are constantly being introduced by companies and inventors worldwide.

The Vietnam War: Reasons for Failure - Why the U.S. Lost
In the post-war era, Americans struggled to absorb the lessons of the military intervention. About the book:
As General Maxwell Taylor, one of the principal architects of the war, noted, First, we didn't know ourselves. We thought that we were going into another Korean War, but this was a different country. Secondly, we didn't know our South Vietnamese allies... And we knew less about North Vietnam. Who was Ho Chi Minh? Nobody really knew. So, until we know the enemy and know our allies and know ourselves, we'd better keep out of this kind of dirty business. It's very dangerous.
Some have suggested that the responsibility for the ultimate failure of this policy [America's withdrawal from Vietnam] lies not with the men who fought, but with those in Congress... Alternatively, the official history of the United States Army noted that tactics have often seemed to exist apart from larger issues, strategies, and objectives. Yet in Vietnam the Army experienced tactical success and strategic failure... The...Vietnam War...legacy may be the lesson that unique historical, political, cultural, and social factors always impinge on the military...Success rests not only on military progress but on correctly analyzing the nature of the particular conflict, understanding the enemy's strategy, and assessing the strengths and weaknesses of allies. A new humility and a new sophistication may form the best parts of a complex heritage left to the Army by the long, bitter war in Vietnam.
U.S. Secretary of State Henry Kissinger wrote in a secret memo to President Gerald Ford that in terms of military tactics, we cannot help draw the conclusion that our armed forces are not suited to this kind of war. Even the Special Forces who had been designed for it could not prevail. Even Secretary of Defense Robert McNamara concluded that the achievement of a military victory by U.S. forces in Vietnam was indeed a dangerous illusion.
Doubts surfaced as to the effectiveness of large-scale, sustained bombing. As Army Chief of Staff Harold Keith Johnson noted, if anything came out of Vietnam, it was that air power couldn't do the job. Even General William Westmoreland admitted that the bombing had been ineffective. As he remarked, I still doubt that the North Vietnamese would have relented.
The inability to bomb Hanoi to the bargaining table also illustrated another U.S. miscalculation. The North's leadership was composed of hardened communists who had been fighting for independence for thirty years. They had defeated the French, and their tenacity as both nationalists and communists was formidable. Ho Chi Minh is quoted as saying, You can kill ten of my men for every one I kill of yours...But even at these odds you will lose and I will win.
The Vietnam War called into question the U.S. Army doctrine. Marine Corps General Victor H. Krulak heavily criticised Westmoreland's attrition strategy, calling it wasteful of American lives... with small likelihood of a successful outcome. In addition, doubts surfaced about the ability of the military to train foreign forces.
Between 1965 and 1975, the United States spent $111 billion on the war ($686 billion in FY2008 dollars). This resulted in a large federal budget deficit.
More than 3 million Americans served in the Vietnam War, some 1.5 million of whom actually saw combat in Vietnam. James E. Westheider wrote that At the height of American involvement in 1968, for example, there were 543,000 American military personnel in Vietnam, but only 80,000 were considered combat troops. Conscription in the United States had been controlled by the President since World War II, but ended in 1973.
By war's end, 58,220 American soldiers had been killed, more than 150,000 had been wounded, and at least 21,000 had been permanently disabled. According to Dale Kueter, Sixty-one percent of those killed were age 21 or younger. Of those killed in combat, 86.3 percent were white, 12.5 percent were black and the remainder from other races. The youngest American KIA in the war was PFC Dan Bullock, who had falsified his birth certificate and enlisted in the US Marines at age 14 and who was killed in combat at age 15. Approximately 830,000 Vietnam veterans suffered symptoms of posttraumatic stress disorder. An estimated 125,000 Americans fled to Canada to avoid the Vietnam draft, and approximately 50,000 American servicemen deserted. In 1977, United States President Jimmy Carter granted a full, complete and unconditional pardon to all Vietnam-era draft dodgers. The Vietnam War POW/MIA issue, concerning the fate of U.S. service personnel listed as missing in action, persisted for many years after the war's conclusion.
Calling All Cars: Gold in Them Hills / Woman with the Stone Heart / Reefers by the Acre
The Los Angeles Police Department (LAPD) is the police department of the city of Los Angeles, California.
The LAPD has been copiously fictionalized in numerous movies, novels and television shows throughout its history. The department has also been associated with a number of controversies, mainly concerned with racial animosity, police brutality and police corruption.
The radio show Calling All Cars hired LAPD radio dispacher Jesse Rosenquist to be the voice of the dispatcher. Rosenquist was already famous because home radios could tune into early police radio frequencies. As the first police radio dispatcher presented to the public ear, his was the voice that actors went to when called upon for a radio dispatcher role.
The iconic television series Dragnet, with LAPD Detective Joe Friday as the primary character, was the first major media representation of the department. Real LAPD operations inspired Jack Webb to create the series and close cooperation with department officers let him make it as realistic as possible, including authentic police equipment and sound recording on-site at the police station.
Due to Dragnet's popularity, LAPD Chief Parker became, after J. Edgar Hoover, the most well known and respected law enforcement official in the nation. In the 1960s, when the LAPD under Chief Thomas Reddin expanded its community relations division and began efforts to reach out to the African-American community, Dragnet followed suit with more emphasis on internal affairs and community policing than solving crimes, the show's previous mainstay.
Several prominent representations of the LAPD and its officers in television and film include Adam-12, Blue Streak, Blue Thunder, Boomtown, The Closer, Colors, Crash, Columbo, Dark Blue, Die Hard, End of Watch, Heat, Hollywood Homicide, Hunter, Internal Affairs, Jackie Brown, L.A. Confidential, Lakeview Terrace, Law & Order: Los Angeles, Life, Numb3rs, The Shield, Southland, Speed, Street Kings, SWAT, Training Day and the Lethal Weapon, Rush Hour and Terminator film series. The LAPD is also featured in the video games Midnight Club II, Midnight Club: Los Angeles, L.A. Noire and Call of Juarez: The Cartel.
The LAPD has also been the subject of numerous novels. Elizabeth Linington used the department as her backdrop in three different series written under three different names, perhaps the most popular being those novel featuring Det. Lt. Luis Mendoza, who was introduced in the Edgar-nominated Case Pending. Joseph Wambaugh, the son of a Pittsburgh policeman, spent fourteen years in the department, using his background to write novels with authentic fictional depictions of life in the LAPD. Wambaugh also created the Emmy-winning TV anthology series Police Story. Wambaugh was also a major influence on James Ellroy, who wrote several novels about the Department set during the 1940s and 1950s, the most famous of which are probably The Black Dahlia, fictionalizing the LAPD's most famous cold case, and L.A. Confidential, which was made into a film of the same name. Both the novel and the film chronicled mass-murder and corruption inside and outside the force during the Parker era. Critic Roger Ebert indicates that the film's characters (from the 1950s) represent the choices ahead for the LAPD: assisting Hollywood limelight, aggressive policing with relaxed ethics, and a straight arrow approach.
Words at War: The Veteran Comes Back / One Man Air Force / Journey Through Chaos
Major Dominic Salvatore Don Gentile (December 6, 1920 - January 28, 1951) was a World War II USAAF pilot who was the first to break Eddie Rickenbacker's World War I record of 26 downed aircraft.
Gentile was born in Piqua, Ohio.[2] After a fascination with flying as a child, his father provided him with his own plane, an Aerosport Biplane. He managed to log over 300 hours flying time by July 1941, when he attempted to join the Army Air Force. The U.S. military required two years of college for its pilots, which Gentile did not have, therefore Gentile originally enlisted in the Royal Canadian Air Force and was posted to the UK in 1941. Gentile flew the Supermarine Spitfire Mark V with No. 133 Squadron, one of the famed Eagle Squadron during 1942. His first kills (a Ju 88 and Fw 190) were on August 1, 1942,[3] during Operation Jubilee.[4]
In September 1942, the Eagle squadrons transferred to the USAAF, becoming the 4th Fighter Group. Gentile became a flight commander in September 1943, now flying the P-47 Thunderbolt. Having been Spitfire pilots, Gentile and the other pilots of the 4th were displeased when they transitioned to the heavy P-47. By late 1943 Group Commander Col. Don Blakeslee pushed for re-equipment with the lighter, more maneuverable, P-51 Mustang. Conversion to the P-51B at the end of February 1944 allowed Gentile to build a tally of 15.5 additional aircraft destroyed between March 3 and April 8, 1944.[5] After downing 3 planes on April 8,[6] he was the top scoring 8th Air Force ace when he crashed his personal P-51, named Shangri La, on April 13, 1944 while stunting over the 4th FG's airfield at Debden for a group of assembled press reporters and movie cameras.
Blakeslee immediately grounded Gentile as a result, and he was sent back to the US for a tour selling War Bonds.
In 1944, Gentile wrote One Man Air Force an autobiography and account of his combat missions with well-known war correspondent, Ira Wolfert.
His final tally of credits was 19.83 aerial victories and 3 damaged,[5] with 6 ground kills, in 350 combat hours flown. He also claimed two victories while with the RAF.
After the war, he stayed with the Air Force, as a test pilot at Wright Field, as a Training Officer in the Fighter Gunnery Program, and as a student officer at the Air Tactical School. In June 1949, Gentile enrolled as an undergraduate studying military science at the University of Maryland.
On January 28, 1951, he was killed when he crashed in a T-33A-1-LO Shooting Star trainer, 49-905, in Forestville, Maryland, leaving behind his wife Isabella Masdea Gentile Beitman (deceased October 2008), and sons Don Jr., Joseph and Pasquale.
Gentile Air Force Station in Kettering, Ohio was named in his honor in 1962. The installation closed in 1996.
Winston Churchill called Gentile and his wingman, Captain John T. Godfrey, Damon and Pythias, after the legendary characters from Greek mythology. He was inducted into the National Aviation Hall of Fame in 1995.[7]
The Great Gildersleeve: Engaged to Two Women / The Helicopter Ride / Leroy Sells Papers
Premiering on August 31, 1941, The Great Gildersleeve moved the title character from the McGees' Wistful Vista to Summerfield, where Gildersleeve now oversaw his late brother-in-law's estate and took on the rearing of his orphaned niece and nephew, Marjorie (originally played by Lurene Tuttle and followed by Louise Erickson and Mary Lee Robb) and Leroy Forester (Walter Tetley). The household also included a cook named Birdie. Curiously, while Gildersleeve had occasionally spoken of his (never-present) wife in some Fibber episodes, in his own series the character was a confirmed bachelor.
In a striking forerunner to such later television hits as Bachelor Father and Family Affair, both of which are centered on well-to-do uncles taking in their deceased siblings' children, Gildersleeve was a bachelor raising two children while, at first, administering a girdle manufacturing company (If you want a better corset, of course, it's a Gildersleeve) and then for the bulk of the show's run, serving as Summerfield's water commissioner, between time with the ladies and nights with the boys. The Great Gildersleeve may have been the first broadcast show to be centered on a single parent balancing child-rearing, work, and a social life, done with taste and genuine wit, often at the expense of Gildersleeve's now slightly understated pomposity.
Many of the original episodes were co-written by John Whedon, father of Tom Whedon (who wrote The Golden Girls), and grandfather of Deadwood scripter Zack Whedon and Joss Whedon (creator of Buffy the Vampire Slayer, Firefly and Dr. Horrible's Sing-Along Blog).
The key to the show was Peary, whose booming voice and facility with moans, groans, laughs, shudders and inflection was as close to body language and facial suggestion as a voice could get. Peary was so effective, and Gildersleeve became so familiar a character, that he was referenced and satirized periodically in other comedies and in a few cartoons.
