What Year did the Event Occur? Quiz

Joseph Swan and Thomas Edison independently developed the incandescent light bulb, with Joseph Swan developing his in 1878 and Thomas Edison securing the patent for his version in 1880. The functioning principle of incandescent bulbs involves passing an electric current through a thin tungsten filament, which heats up to a point where it emits visible light due to incandescence.

The invention of the light bulb brought numerous significant advancements, particularly in improving safety and extending functionality in various aspects of daily life. The risk of fire-related accidents was considerably reduced by eliminating the need for open flames to provide illumination. This invention extended productive hours beyond daylight, facilitating social interactions after dark. Additionally, it greatly aided the medical field, enabling doctors and nurses to perform surgeries and other critical procedures with improved visibility.

Today there are three primary categories of light bulbs: incandescent, fluorescent, and LED (light-emitting diode). Different light sources exhibit unique efficiency, longevity, and color temperature parameters.

The "Wall Street Journal", commonly referred to as the "Journal", is an American newspaper established on July 8, 1889, by Charles Dow, Edward Jones, and Charles Bergstresser. The first issue, comprising four pages, was priced at 2 cents.

The publication, still in print today, primarily focuses on analytical coverage of business, finance, economics, politics, and national and international news, serving as a critical resource for professionals seeking in-depth insights into these sectors.

William McKinley served as the 25th President of the United States from 1897 until his assassination in 1901. On September 6, 1901, he was shot by anarchist Leon Czolgosz at the Pan-American Exposition in Buffalo, New York. The reason for the assassination was that Leon Czolgosz viewed McKinley as an overbearing symbol and believed that killing him was his duty.

Following the attack, McKinley succumbed to his injuries, specifically a gangrene infection that developed within the gunshot wound, resulting in his death on September 14, 1901. Leon Czolgosz was executed by electric chair on October 29, 1901, for the assassination of William McKinley.

The "RMS Lusitania" was a British ocean liner, launched on June 7, 1906. On May 7, 1915, the vessel was struck by a torpedo fired from a German U-boat because they thought the ship was carrying war supplies. It sank approximately 11 miles (18 km) off the southern coast of Ireland within a rapid 18 minutes. The disaster resulted in the loss of 1,197 lives, including both passengers and crew.

The sinking of the "RMS Lusitania" had significant ramifications, particularly contributing to the United States' entry into World War I. It prompted widespread international disapproval, which shifted public opinion against Germany. Additionally, it strained German-American relations and ultimately led to Germany reevaluating its unrestricted submarine warfare policies.

Regarding its specifications, the "RMS Lusitania" measured 787 feet (239.9 meters) in length and stood 104 feet (31.7 meters) tall from the keel to the apex of the boat deck. The ship was powered by four triple-blade propellers and featured four distinct funnels, a hallmark of its era's engineering design.

The Vietnam War was a prolonged conflict that occurred in Vietnam, Laos, and Cambodia from November 1, 1955, to April 30, 1975.

The conflict was intricately linked to the geopolitical rivalries originating from the Cold War era. A pivotal moment was the Gulf of Tonkin Incident, which occurred when North Vietnamese forces engaged two U.S. Navy destroyers in the Gulf of Tonkin. This incident triggered increased U.S. military involvement in the region, driven primarily by restraining Soviet influence in Southeast Asia and preventing the further expansion of communism.

The war resulted in staggering casualties, with estimates predicting over 1.3 million military deaths among North Vietnamese forces, approximately 58,000 U.S. military personnel killed, and more than 2 million civilian fatalities. Ultimately, the North Vietnamese emerged victorious.

The Gateway Arch, often referred to as the Gateway to the West, is a monumental structure located in St. Louis, Missouri, USA. The construction of the Arch commenced on February 12, 1963, and concluded on October 28, 1965.

The primary intent behind the construction of The Gateway Arch was to symbolize Thomas Jefferson's ambition for a transcontinental United States.

This iconic structure reaches a height and width of 630 feet (192 meters) and was constructed at a cost of approximately $13 million. It was designed by architect Eero Saarinen, with structural engineering provided by Severud Associates.

The Concorde was a supersonic passenger airliner operated by Air France and British Airways from March 2, 1969, until October 24, 2003. The prototype, Concorde 001, conducted its inaugural test flight from Toulouse, France, on March 2, 1969, and commercial operations began in 1976.

The Concorde had several remarkable features in aerospace engineering. It was capable of flying at twice the speed of sound. It operated at altitudes higher than conventional commercial aircraft. Its unique droop-down nose design enhanced its aerodynamics during takeoff and landing, allowing it to break the sound barrier. Its distinctive delta wing configuration contributed to both its lift characteristics and supersonic capabilities.

Design specifications include a length of 202 feet 4 inches (61.66 meters) and a height of 40 feet (12.2 meters). The aircraft had a passenger capacity ranging from 92 to 120, depending on configuration. It achieved a remarkable maximum cruising speed of 1,354 mph (2,179 km/h) and could climb to altitudes of 60,000 feet (18,290 meters).

The West Gate Bridge is a notable steel box-girder and cable-stayed structure that opened in 1978 and is located in Melbourne, Victoria, Australia.

During its construction on October 15, 1970, a critical event occurred when a 112-meter (367-foot) segment of the bridge collapsed at approximately 11:50 am. This resulted in a free fall from a height of 50 meters (164 feet) to the ground and the adjacent waterway.

This catastrophic failure resulted in the tragic loss of thirty-five construction workers, with an additional eighteen sustaining injuries.

The Sydney Opera House is a prominent multi-venue performing arts center located in Sydney, New South Wales, Australia. Construction commenced on March 1, 1959, and the complex was opened on October 20, 1973.

The structure reaches a height of 65 meters (213 feet) and spans a length of 183 meters (600 feet), covering a total area of 1.8 hectares (4.4 acres). The Opera House, which has a seating capacity of 5,738, was developed at a cost of $102 million.

The Oklahoma City bombing was a tragic act of domestic terrorism that took place on April 19, 1995. A large truck filled with explosives was parked outside the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma.

At around 9:02 in the morning, the bomb went off, resulting in the deaths of 168 people. The attack was carried out by two men named Timothy James McVeigh and Terry Lynn Nichols, who had strong anti-government beliefs.

Timothy James McVeigh stated that he detonated a bomb at the Alfred P. Murrah Federal Building as retaliation against the U.S. government for its actions during the Waco siege in 1993 and the Ruby Ridge confrontation.

Timothy James McVeigh was put to death by lethal injection on June 11, 2001, for his crimes. Terry Lynn Nichols, was given a life sentence in prison without any chance to be released on June 4, 1998.
