History of Maryland

In 1781, during the American Revolutionary War (1775–1783), Maryland became the thirteenth state of the United States to ratify the Articles of Confederation and Perpetual Union.  They were drawn up by a committee of the Second Continental Congress (1775–1781), which began shortly after the adoption of a Declaration of Independence in July 1776, through to 1778. Later that year, these Articles were recommended to the newly independent sovereign states via their legislatures for the required unanimous ratification. This long process was held up for three years by objections from smaller states led by Maryland until certain issues and principles over the western lands beyond  the Appalachian Mountains to the Mississippi River. These objections were resolved with the larger states agreeing to cede their various western claims to the authority of the new Congress of the Confederation, representing all the states, to be held in common for the laying out and erection of new states out of the jointly held Federal territories. Maryland then finally agreed to join the new American confederation by being one of the last of the former colonies ratifying the long proposed Articles in 1781, when they took effect.

Question: When was Maryland established?
Answer: July 1776
Microwave oven

In 1947, Raytheon built the "Radarange", the first commercially available microwave oven.[13] It was almost 1.8 metres (5ft 11in) tall, weighed 340 kilograms (750lb) and cost about US$5,000 ($56,000 in 2018 dollars) each. It consumed 3 kilowatts, about three times as much as today's microwave ovens, and was water-cooled. The name was the winning entry in an employee contest.[14] An early Radarange was installed (and remains) in the galley of the nuclear-powered passenger/cargo ship NS Savannah. An early commercial model introduced in 1954 consumed 1.6 kilowatts and sold for US$2,000 to US$3,000 ($19,000 to $28,000 in 2018 dollars). Raytheon licensed its technology to the Tappan Stove company of Mansfield, Ohio in 1952.[15] They tried to market a large 220 volt wall unit as a home microwave oven in 1955 for a price of US$1,295 ($12,000 in 2018 dollars), but it did not sell well.

Question: How much did the first microwave oven cost?
Answer: about US$5,000

Battle of Chosin Reservoir

Roy E. Appleman, the author of US Army official history South to Naktong, North to Yalu, writes that both sides could claim victory: the PVA 9th Army ultimately held the battlefield, while X Corps held off the Chinese 9th Army in a series of battles that enabled it to withdraw most of its forces as an effective tactical unit.[1]:355–6 Allan R. Millett qualifies a Chinese "geographic victory" that ejected X Corps from North Korea with the fact that the Chinese failed to achieve the objective of destroying the 1st Marine Division, adding that the campaign gave the UN confidence that it could withstand the superior numbers of the Chinese forces.[49] The official Chinese history, published by PLA Academy of Military Science, states that despite the heavy casualties, the PVA 9th Army had earned its victory by successfully protecting the eastern flank of Chinese forces in Korea, while inflicting over 10,000 casualties to the UN forces.[50]

Question: Who won the Battle of Jangjin Lake?
Answer: both sides could claim victory
Alan L. Hart

Alan Lucille Hart was born October 4, 1890, in Halls Summit, Coffey County, Kansas, to Albert L. Hart and Edna Hart (née Bamford). When his father died of typhoid fever in 1892, his mother reverted to her maiden name and moved the family to Linn County, Oregon, where she cared for her own mother during a period of sickness. When Hart was five years old his mother remarried, to Bill Barton, and the family moved to Edna's father's farm. Hart wrote later, in 1911, of his happiness during this time, when he was free to present as male, playing with boys' toys made for him by his grandfather. His parents and grandparents largely accepted and supported his gender expression, though his mother described his "desire to be a boy" as "foolish." His grandparents' obituaries, from 1921 and 1924, both list Hart as a grandson.[2] When Hart was 12 the family moved to Albany. There Hart was obliged to present as female to attend school, where he was treated as a girl. He continued to spend the holidays at his grandfather's farm, presenting as male among his male friends, "teasing the girls and playing boy's games".[3] According to a reminiscence piece in the Halls Summit News of June 10, 1921, "Young Hart was different, even then. Boys' clothes just felt natural. [Alan] always regarded [him]self as a boy and begged [his] family to cut [his] hair and let [him] wear trousers. [Alan] disliked dolls but enjoyed playing doctor. [He] hated traditional girl tasks, preferring farm work with the menfolk instead. The self reliance that became a lifelong trait was evident early: once when [he] accidentally chopped off [his] fingertip with an axe, [Alan] dressed it [him]self, saying nothing about it to the family."[4]

Question: Where was Alan L. Hart born?
Answer: Halls Summit, Coffey County, Kansas

Nakiri bōchō

Nakiri bōchō (菜切り包丁, translation: knife for cutting greens) and usuba bōchō (薄刃包丁, thin knife) are Japanese-style vegetable knives. They differ from the deba bōchō in their shape, as they have a straight blade edge suitable for cutting all the way to the cutting board without the need for a horizontal pull or push.[1] These knives are also much thinner. While the deba bōchō is a heavy blade for easy cutting through thin bones, the blade is not suitable for chopping vegetables, as the thicker blade can break the vegetable slice. The nakiri bōchō and the usuba bōchō have a much thinner blade. This does not help with cutting small bones in fish or meat, but is useful for cutting vegetables.

Question: What is a nakiri?
Answer: knife for cutting greens

The red wolf (Canis lupus rufus[6][7] or Canis rufus[4]) is a canine native to the southeastern United States. The subspecies is the product of ancient genetic admixture between the gray wolf and the coyote,[8][9] however it is regarded as unique and therefore worthy of conservation.[10] Morphologically it is intermediate between the coyote and gray wolf, and is of a reddish, tawny color.[11][12] The US Endangered Species Act of 1973 currently does not provide protection for endangered admixed individuals and researchers argue that these should warrant full protection under the Act.[8][10] However, the red wolf when considered as a species is listed as an endangered species under this Act and is protected by law.[13] Although Canis rufus is not listed in the CITES Appendices of endangered species,[2] since 1996 the IUCN has listed it as a critically endangered species.[2]

Beta oxidation

In biochemistry and metabolism, beta-oxidation is the catabolic process by which fatty acid molecules are broken down[1] in the cytosol in prokaryotes and in the mitochondria in eukaryotes to generate acetyl-CoA, which enters the citric acid cycle, and NADH and FADH2, which are co-enzymes used in the electron transport chain. It is named as such because the beta carbon of the fatty acid undergoes oxidation to a carbonyl group. Beta-oxidation is primarily facilitated by the mitochondrial trifunctional protein, an enzyme complex associated with the inner mitochondrial membrane, although very long chain fatty acids are oxidized in peroxisomes.

Question: What happens in oxidation?
Answer: fatty acid molecules are broken down[1] in the cytosol in prokaryotes and in the mitochondria in eukaryotes to generate acetyl-CoA, which enters the citric acid cycle, and NADH and FADH2, which are co-enzymes used in the electron transport chain

Mercury-in-glass thermometer

The mercury-in-glass or mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit in Amsterdam (1714). It consists of a bulb containing mercury attached to a glass tube of narrow diameter; the volume of mercury in the tube is much less than the volume in the bulb. The volume of mercury changes slightly with temperature; the small change in volume drives the narrow mercury column a relatively long way up the tube. The space above the mercury may be filled with nitrogen gas or it may be at less than atmospheric pressure, a partial vacuum.

Question: When was the mercury thermometer invented?
Answer: 1714
