The outreach director of HRTR, Susan Prager, is also the communication director of "Friends of Falun Gong", a quasi-government non-profit funded by fmr. Congressman Tom Lanto's wife and Ambassador Mark Palmer of NED. A major setback to the event was caused by footballer Diego Maradona, scheduled to open the relay through Buenos Aires, pulling out in an attempt to avoid the Olympic controversy. Trying to avoid the scenes that marred the relay in the UK, France and the US, the city government designed a complex security operative to protect the torch relay, involving 1200 police officers and 3000 other people, including public employees and volunteers. Overall, the protests were peaceful in nature, although there were a few incidents such as the throwing of several water balloons in an attempt to extinguish the Olympic flame, and minor scuffles between Olympic protesters and supporters from Chinese immigrant communities.
How many police officers were part of the security operative?
****
The answer: 1200

Mechanical analog computers started appearing in the first century and were later used in the medieval era for astronomical calculations. In World War II, mechanical analog computers were used for specialized military applications such as calculating torpedo aiming. During this time the first electronic digital computers were developed. Originally they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).
What were analog computers originally used for?
****
The answer: astronomical calculations

Thermal conductivity gauges rely on the fact that the ability of a gas to conduct heat decreases with pressure. In this type of gauge, a wire filament is heated by running current through it. A thermocouple or Resistance Temperature Detector (RTD) can then be used to measure the temperature of the filament. This temperature is dependent on the rate at which the filament loses heat to the surrounding gas, and therefore on the thermal conductivity. A common variant is the Pirani gauge which uses a single platinum filament as both the heated element and RTD. These gauges are accurate from 10 torr to 103 torr, but they are sensitive to the chemical composition of the gases being measured.
The fact that gases ability to conduct heat decreases with pressure is used by what form of measurement?
****
The answer: Thermal conductivity gauges

On August 19, 1989, the Russian Orthodox Parish of Saints Peter and Paul announced it would be switching to the Ukrainian Autocephalous Orthodox Church. On September 2, 1989, tens of thousands across Ukraine protested a draft election law that reserved special seats for the Communist Party and for other official organizations: 50,000 in Lviv, 40,000 in Kiev, 10,000 in Zhytomyr, 5,000 each in Dniprodzerzhynsk and Chervonohrad, and 2,000 in Kharkiv. From September 810, 1989, writer Ivan Drach was elected to head Rukh, the People's Movement of Ukraine, at its founding congress in Kiev. On September 17, between 150,000 and 200,000 people marched in Lviv, demanding the legalization of the Ukrainian Greek Catholic Church. On September 21, 1989, exhumation of a mass grave begins in Demianiv Laz, a nature preserve south of Ivano-Frankivsk. On September 28, First Secretary of the Communist Party of the Ukraine Volodymyr Shcherbytsky, a holdover from the Brezhnev era, was replaced by Vladimir Ivashko.
How many protesters were there in Lviv?
****
The answer:
50,000
