This method of farming uses "steps" that are built into the side of a mountain or hill. On each level, various crops are planted. When it rains, instead of washing away all of the nutrients in the soil, the nutrients are carried down to the next level. These steps prevent water from washing away the soil and plants. This system also allowed them to build aqueducts, which carried water to each level.
The idea was also independently developed by the Inca people. The Incas built their aqueduct system so well that it is still used today.
Sapa Inca
Sapa Inca was the Inca emperor. "" means "The Great Inca" or "The Only Inca" in Quechua, the Inca language. According to legend, the first Sapa Inca, Manco Cápac (c. 1200 CE- 1230) was the son of the sun god, Inti. Manco Cápac became Sapa Inca by founding the city of Cuzco after he was sent on a quest by a god to find a good location for a city and build one. He also united the tribes around Cuzco.
The position of Sapa Inca was hereditary, which means that it passed from father to son. The Sapa Inca was the sole and absolute ruler over the Incas. His word was law, and he was the supreme commander of the military. The Sapa Inca lived in great luxury with many wives, slaves, and riches. Another privilege that he had was that he was allowed to (and usually would) marry his sister even though it was prohibited for common people. When the Sapa Inca died he would be mummified.
The Inca Empire reached its height under Huayna Capac (1493–1527) when it stretched from modern day Argentina to Ecuador, although Tupac Inca Yupanqui (1471-1493) was responsible for expanding much of the empire to those borders. Tupac Yupanqui conquered the Kingdom of Chimor, the biggest rival to the Inca. He expanded the empire into modern day Ecuador, Peru, and Bolivia. Atahualpa was the last pre-conquest Sapa Inca. He was killed by the invading Spaniards in 1533 and after that there were several Sapa Inca who were installed by the Spanish. The last person to hold the title was Tupac Amaru who was killed by the Spanish in 1572.
STS-1
STS-1 was the first flight of the space shuttle. It launched on April 12, 1981 and landed on April 14. It was launched 20 years after the first manned space flight. The space shuttle used was "Columbia". Space Shuttle Columbia orbited the Earth 37 times in this mission.
STS-1 was the first of two missions with a painted external tank. The paint was put to protect the external tank from ultraviolet light when it was standing on the launch pad. After STS-2, the paint was removed
Omar Hassan Ahmad al-Bashir
Omar Hassan Ahmad al-Bashir (; born 1944) is the former President of Sudan. He came into power in 1989 and resigned in 2019 following massive anti-protests and a coup. In October 2004, Omar's government negotiated an end to the second Sudanese civil war, one of the longest-running and deadliest wars of the 20th century. However, there has been a violent conflict in Darfur that has resulted in a death toll between 200,000 and 400,000. During his presidency, there have been several violent struggles between the rebel groups such as the Sudanese Liberation Army (SLA) and the Justice and Equality Movement (JEM) in the form of warfare in the Darfur region. The civil war has resulted in over 2.5 million people being displaced, and the relations between Sudan and Chad are at a crisis.

More generally, the substitute of one response by another, when the original response is blocked: displaced aggression.
Ego depletion
Ego depletion is the idea that people get tired of making decisions because it is a neuro-chemical process that requires energy.
Central dogma of molecular biology
The central dogma of molecular biology is a phrase by Francis Crick, who proposed the double helix structure of DNA.
It means that information passes from DNA to proteins via RNA, but proteins cannot pass the information back to DNA.
Crick first wrote it in 1958, and repeated it in 1970.
The dogma is a framework for understanding the transfer of sequence information.
There are 3 major classes of such biopolymers: DNA and RNA (both nucleic acids), and protein. There are 3×3 = 9 conceivable direct transfers of information that can occur between these. The dogma classes these into 3 groups of 3:
The general transfers describe the normal flow of biological information: DNA can be copied to DNA (DNA replication), DNA information can be copied into mRNA, (transcription), and proteins can be synthesized using the information in mRNA as a template (translation).
The dogma is a modern version of the Weismann barrier (after August Weismann). This is the principle that hereditary information moves only from genes to body cells, and never in reverse. Hereditary information moves only from germline cells to somatic cells.
Ubar
Ubar is a ruined city in Oman. English adventurer Ranulph Fiennes discovered the city in 1992. According to Nicolas Clapp, this probably is the lost city Iram of the Pillars the Qu'ran talks about.
Today, ruins are left, which can be reached in a four-wheel drive. Part of the area forms the ceiling to underground vaults, which have collapsed. These vaults hold water supplies for a nearby settlement, which houses a small museum.
