Problem: Richard Feynman:

Feynman's other work at Los Alamos included calculating neutron equations for the Los Alamos "Water Boiler", a small nuclear reactor, to measure how close an assembly of fissile material was to criticality. On completing this work he was transferred to the Oak Ridge facility, where he aided engineers in devising safety procedures for material storage so that criticality accidents (for example, due to sub-critical amounts of fissile material inadvertently stored in proximity on opposite sides of a wall) could be avoided. He also did theoretical work and calculations on the proposed uranium hydride bomb, which later proved not to be feasible.

Where was the "Water Boiler" worked on without Feynman?

Problem: Namibia (i/nmbi/, /n-/), officially the Republic of Namibia (German: Republik Namibia (helpinfo); Afrikaans: Republiek van Namibie) is a country in southern Africa whose western border is the Atlantic Ocean. It shares land borders with Zambia and Angola to the north, Botswana to the east and South Africa to the south and east. Although it does not border Zimbabwe, a part of less than 200 metres of the Zambezi River (essentially a small bulge in Botswana to achieve a Botswana/Zambia micro-border) separates it from that country. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. Its capital and largest city is Windhoek, and it is a member state of the United Nations (UN), the Southern African Development Community (SADC), the African Union (AU), and the Commonwealth of Nations.

There are many art galleries in Utrecht. There are also several foundations to support art and artists. Training of artists is done at the Utrecht School of the Arts. The Centraal Museum has many exhibitions on the arts, including a permanent exhibition on the works of Utrecht resident illustrator Dick Bruna, who is best known for creating Miffy ("Nijntje", in Dutch). Although street art is illegal in Utrecht, the Utrechtse Kabouter, a picture of a gnome with a red hat, became a common sight in 2004. Utrecht also houses one of the landmarks of modern architecture, the 1924 Rietveld Schroder House, which is listed on UNESCO's world heritage sites.

Context and question: Commercial CSP plants were first developed in the 1980s. Since 1985 the eventually 354 MW SEGS CSP installation, in the Mojave Desert of California, is the largest solar power plant in the world. Other large CSP plants include the 150 MW Solnova Solar Power Station and the 100 MW Andasol solar power station, both in Spain. The 250 MW Agua Caliente Solar Project, in the United States, and the 221 MW Charanka Solar Park in India, are the world's largest photovoltaic plants. Solar projects exceeding 1 GW are being developed, but most of the deployed photovoltaics are in small rooftop arrays of less than 5 kW, which are grid connected using net metering and/or a feed-in tariff. In 2013 solar generated less than 1% of the worlds total grid electricity.
Where is the largest solar power plant in the world located?
Answer: Mojave Desert of California

Question: Temperatures below 0 C (32 F) or above 25 C (77 F) are rare. Cork Airport records an average of 1,227.9 millimetres (4.029 ft) of precipitation annually, most of which is rain. The airport records an average of 7 days of hail and 11 days of snow or sleet a year; though it only records lying snow for 2 days of the year. The low altitude of the city, and moderating influences of the harbour, mean that lying snow very rarely occurs in the city itself. There are on average 204 "rainy" days a year (over 0.2 millimetres (0.0079 in) of rainfall), of which there are 73 days with "heavy rain" (over 5 millimetres (0.20 in)). Cork is also a generally foggy city, with an average of 97 days of fog a year, most common during mornings and during winter. Despite this, however, Cork is also one of Ireland's sunniest cities, with an average of 3.9 hours of sunshine every day and only having 67 days where there is no "recordable sunshine", mostly during and around winter.
Is there an answer to this question: How much precipitation does Cork usually receive?

Answer: 1,227.9 millimetres (4.029 ft)
