The art of mechanical analog computing reached its zenith with the differential analyzer, built by H. L. Hazen and Vannevar Bush at MIT starting in 1927. This built on the mechanical integrators of James Thomson and the torque amplifiers invented by H. W. Nieman. A dozen of these devices were built before their obsolescence became obvious.
The differential analyzer by H.L. Hazen and Vannevar Bush was first being built in what year?
****
The answer: 1927

The problem: Answer a question about this article:
On basic Church teachings, the pope was unwavering. On the tenth anniversary of Humanae vitae, he reconfirmed this teaching. In his style and methodology, he was a disciple of Pius XII, whom he deeply revered. He suffered for the attacks on Pius XII for his alleged silences during the Holocaust. Pope Paul VI was less outstanding than his predecessors: he was not credited with an encyclopedic memory, nor a gift for languages, nor the brilliant writing style of Pius XII, nor did he have the charisma and outpouring love, sense of humor and human warmth of John XXIII. He took on himself the unfinished reform work of these two popes, bringing them diligently with great humility and common sense and without much fanfare to conclusion. In doing so, Paul VI saw himself following in the footsteps of the Apostle Paul, torn to several directions as Saint Paul, who said, "I am attracted to two sides at once, because the Cross always divides."
On which anniversary of his Humanae Vitae did Paul VI reconfirm the beliefs set forth by the Humanae Vitae?
****
The answer: tenth

The problem: Answer a question about this article:
In nature, uranium is found as uranium-238 (99.2742%) and uranium-235 (0.7204%). Isotope separation concentrates (enriches) the fissionable uranium-235 for nuclear weapons and most nuclear power plants, except for gas cooled reactors and pressurised heavy water reactors. Most neutrons released by a fissioning atom of uranium-235 must impact other uranium-235 atoms to sustain the nuclear chain reaction. The concentration and amount of uranium-235 needed to achieve this is called a 'critical mass'.
What is the term for the amount of uranium-235 needed to sustain a nuclear chain reaction?
****
The answer:
critical mass
