Hydrogen bond

Hydrogen bonds can be intermolecular (occurring between separate molecules) or intramolecular (occurring among parts of the same molecule).[4] Depending on the nature of the donor and acceptor atoms which constitute the bond, their geometry, and environment, the energy of a hydrogen bond can vary between 1 and 40 kcal/mol.[5] This makes them somewhat stronger than a van der Waals interaction, and weaker than fully covalent or ionic bonds. This type of bond can occur in inorganic molecules such as water and in organic molecules like DNA and proteins.

Question: What is the strength of a hydrogen bond?
Answer: between 1 and 40 kcal/mol

International Ladies' Garment Workers' Union

The ILGWU was founded on June 3, 1900[2] in New York City by seven local unions, with a few thousand members between them. The union grew rapidly in the next few years but began to stagnate as the conservative leadership favored the interests of skilled workers, such as cutters. This did not sit well with the majority of immigrant workers, particularly Jewish workers with a background in Bundist activities in Tsarist Russia, or with Polish and Italian workers, many of whom had strong socialist and anarchist leanings.

Question: When was the International Ladies' Garment Workers' Union formed?
Answer: June 3, 1900

It was fought May 12 and 13, 1865, on the banks of the Rio Grande east of Brownsville, Texas and a few miles from the seaport of Los Brazos de Santiago. Since the Confederacy had ceased to exist, it is also argued that this battle should be classified as a postwar action.

Question: What was the last Confederate victory in the Civil War?
Answer: Battle of Palmito Ranch
Grand Canal (China)

The Grand Canal, known to the Chinese as the Beijing–Hangzhou Grand Canal (Jīng-Háng Dà Yùnhé), a UNESCO World Heritage Site, is the longest as well as the oldest canal or artificial river in the world.[1] Starting at Beijing, it passes through Tianjin and the provinces of Hebei, Shandong, Jiangsu and Zhejiang to the city of Hangzhou, linking the Yellow River and Yangtze River.

History of science fiction films

Science fiction films appeared very early in the silent film era. The initial attempts were short films of typically 1 to 2 minutes in duration, shot in black and white, but sometimes with colour tinting. These usually had a technological theme, and were often intended to be humorous. Le Voyage dans la Lune, created by Georges Méliès in 1902 is often considered to be the first science fiction film. It drew upon Jules Verne and H. G. Wells in its depiction of a spacecraft being launched to the moon in a large cannon.[1] Its ground-breaking special effects pioneered the way for future science-fiction films, and it became largely popular after its release.[2]

Question: What was the first movie about space?
Answer: Le Voyage dans la Lune

1899 San Ciriaco hurricane

1899 San Ciriaco hurricane, also known as the 1899 Puerto Rico Hurricane or The Great Bahamas Hurricane of 1899, was the longest-lived Atlantic hurricane on record, and the second-longest-lived tropical cyclone globally on record (in terms of tropical duration) after Hurricane John in the Pacific. The third tropical cyclone and first major hurricane of the season, this storm was first observed southwest of Cape Verde on August3. It slowly strengthened while heading steadily west-northwestward across the Atlantic Ocean and reached hurricane status by late on August5. During the following 48hours, it deepened further, reaching Category4 on the modern day Saffir–Simpson hurricane wind scale (SSHWS) before crossing the Leeward Islands on August7. Later that day, the storm peaked winds of 150mph (240km/h). The storm weakened slightly before making landfall in Guayama, Puerto Rico with winds of 140mph (220km/h) on August8. Several hours later, it emerged into the southwestern Atlantic as a Category3 hurricane. The system paralleled the north coast of Dominican Republic and then crossed the Bahamas, striking several islands. Thereafter, it began heading northward on August14, while centered east of Florida. Early on the following day, the storm re-curved northeastward and appeared to be heading out to sea. However, by August17, it turned back to the northwest and made landfall near Hatteras, North Carolina early on the following day. No stronger hurricane has made landfall on the Outer Banks since the San Ciriaco hurricane.

Question: Where did the San Ciriaco hurricane make landfall?

South Pole

The South Pole is at an altitude of 9,300 feet (2,800m) but feels like 11,000 feet (3,400m).[29]. Centrifugal force from the spin of the planet pulls the atmosphere toward the equator. The South Pole is colder than the North Pole because of the elevation difference.[30] The North Pole is a few feet from sea level.

Question: Which is colder North Pole or South Pole?
Answer: The South Pole
Anushilan Samiti

By 1902, Calcutta had three secret societies working toward the violent overthrow of British rule in India. One was founded by Calcutta student Satish Chandra Basu with the patronage of Calcutta barrister Pramatha Mitra, another was led by Bengali woman Sarala Devi and the third was founded by Aurobindo Ghosh. Ghosh was one of the strongest proponents of militant Indian nationalism at the time.[5][6] By 1905 the work of Aurobindo and his brother, Barin, enabled Anushilan Samity to spread throughout Bengal. Nationalist writings and publications by Aurobindo and Barin, including Bande Mataram and Jugantar, had a widespread influence on Bengal youth. The 1905 partition of Bengal stimulated radical nationalist sentiments in Bengal's Bhadralok community, helping Anushilan acquire a support base of educated, politically-conscious and disaffected members of local youth societies. Its program emphasized physical training, training its recruits with daggers and lathis (bamboo staffs used as weapons). The Dhaka branch of Anushilan was led by Pulin Behari Das, and branches spread throughout East Bengal and Assam.[7] More than 500 branches were opened in eastern Bengal and Assam, linked by "close and detailed organization" to Pulin's headquarters at Dhaka. It absorbed smaller groups in the province, soon overshadowing its parent organisation in Calcutta. Branches of Dhaka Anushilan emerged in Jessore, Khulna, Faridpur, Rajnagar, Rajendrapur, Mohanpur, Barvali and Bakarganj. Estimates of Dhaka Anushilan Samiti's reach indicate a membership of 15,000 to 20,000. Within two years, Dhaka Anushilan devolved its aims from the Swadeshi to that of political terrorism.[8][9]

Question: How many people joined the Anushilan Samiti?
Answer: 15,000 to 20,000

Sport utility vehicle

According to Robert Casey, the transportation curator at the Henry Ford Museum, the 1984 Jeep Cherokee (XJ) was the first true sport utility vehicle in the modern understanding of the term,[44] although Jeep already used the term literally in their 1974 brochures, for the original SJ Cherokee.[30][31] Developed under the leadership of AMC's François Castaing and marketed to urban families as a substitute for a traditional car (and especially station wagons, which were still fairly popular at the time), the Cherokee had four-wheel drive in a more manageable size (compared to the full-size Wagoneer) as well as a plush interior resembling a station wagon.[44] With the introduction of more luxurious models and a much more powerful 4-liter engine, sales of the Cherokee increased even higher as the price of gasoline fell, and the term "sport utility vehicle" began to be used in the national press for the first time.[44] "The advent and immediate success of AMC/Jeep's compact four-door Cherokee turned the truck industry upside down."[45]

Question: What was the first car classified as an SUV?
Answer: 1984 Jeep Cherokee (XJ)

Anatolian Shepherd

The general appearance of the Anatolian Shepherd Dog is a tall, rugged and powerful livestock guardian dog with a dense double coat, a broad strong head, well-developed muscular shoulders, and a long tail with a slight curl (reaching to the hock), that is carried high and curled over the dog's back when the dog is alert.   The physique embodies balance and strength.  Movement of the Anatolian Shepherd Dog should be supple and powerful.  A low head carriage which shows the head, neck and topline being level when moving - creating the impression that the dog is stalking - is an important characteristic of the breed[14]. As with many breeds, there are several breed standards for the Anatolian Shepherd Dog, and therefore there is some variance in the described size and weight. They weigh between 40 and 70kg (90 and 150 pounds), with females on the smaller side and males on the larger side. The coat may be any colour, although most common are white cream, "sesame," and white with large coloured spots that do not cover more than 30% of the body. Known as piebald, these colours may or may not be accompanied by a black mask and/or ears. They have a thick double coat that is somewhat wiry, and needs to be brushed 1-2 times a week in warm weather due to excessive shedding. They have very thick hair on their neck to protect their throat. They look as if they are heavier than they actually are, due to the thick coat.

Question: How large is an Anatolian Shepard?
Answer: between 40 and 70kg (90 and 150 pounds)

Wolfenstein

The Wolfenstein series of video games started with the 1981 stealth-adventure video game Castle Wolfenstein. It was developed by American programmer Silas Warner, a pioneer in the early eras of video gaming, especially the stealth genre. It was published by his (then) company M.U.S.E. Inc. (Muse Software). The player controls an unnamed American prisoner of war as he steals war files containing information about secret German war plans while avoiding or sometimes killing guards, and tries to escape the fortified Nazi stronghold Castle Wolfenstein, set during World War II. The game is often credited as one of the first video games of the stealth genre, since it focuses more on avoiding or disarming enemies, and killing them is considered a last resort.[2]

Question: Who created the game Return to Castle Wolfenstein?
Answer: Silas Warner
Himalayas

The Himalayas are inhabited by 52.7 million people,[5] and are spread across five countries: Nepal, India, Bhutan, China and Pakistan.  Some of the world's major rivers — the Indus, the Ganges and the Tsangpo-Brahmaputra — rise in the Himalayas, and their combined drainage basin is home to roughly 600 million people.  The Himalayas have a profound effect on the climate of the region, helping to keep the monsoon rains on the Indian plain and limiting rainfall on the Tibetan plateau. The Himalayas have profoundly shaped the cultures of the Indian subcontinent; many Himalayan peaks are sacred in Hinduism and Buddhism.

Question: Which countries are spanned by the Himalayas?
Answer: Nepal, India, Bhutan, China and Pakistan
