QUES: The March 1906 Scientific American article by American pioneer William E. Meacham explained the basic principle of hydrofoils and hydroplanes. Bell considered the invention of the hydroplane as a very significant achievement. Based on information gained from that article he began to sketch concepts of what is now called a hydrofoil boat. Bell and assistant Frederick W. "Casey" Baldwin began hydrofoil experimentation in the summer of 1908 as a possible aid to airplane takeoff from water. Baldwin studied the work of the Italian inventor Enrico Forlanini and began testing models. This led him and Bell to the development of practical hydrofoil watercraft.

QUES: Rome's diplomatic agreement with her neighbours of Latium confirmed the Latin league and brought the cult of Diana from Aricia to the Aventine. and established on the Aventine in the "commune Latinorum Dianae templum": At about the same time, the temple of Jupiter Latiaris was built on the Alban mount, its stylistic resemblance to the new Capitoline temple pointing to Rome's inclusive hegemony. Rome's affinity to the Latins allowed two Latin cults within the pomoerium: and the cult to Hercules at the ara maxima in the Forum Boarium was established through commercial connections with Tibur. and the Tusculan cult of Castor as the patron of cavalry found a home close to the Forum Romanum: Juno Sospita and Juno Regina were brought from Italy, and Fortuna Primigenia from Praeneste. In 217, Venus was brought from Sicily and installed in a temple on the Capitoline hill.

For what group was Castor a patron?

QUES: In 1928, he earned a doctorate in psychology, under the supervision of Karl Buhler. His dissertation was entitled "Die Methodenfrage der Denkpsychologie" (The question of method in cognitive psychology). In 1929, he obtained the authorisation to teach mathematics and physics in secondary school, which he started doing. He married his colleague Josefine Anna Henninger (19061985) in 1930. Fearing the rise of Nazism and the threat of the Anschluss, he started to use the evenings and the nights to write his first book Die beiden Grundprobleme der Erkenntnistheorie (The Two Fundamental Problems of the Theory of Knowledge). He needed to publish one to get some academic position in a country that was safe for people of Jewish descent. However, he ended up not publishing the two-volume work, but a condensed version of it with some new material, Logik der Forschung (The Logic of Scientific Discovery), in 1934. Here, he criticised psychologism, naturalism, inductionism, and logical positivism, and put forth his theory of potential falsifiability as the criterion demarcating science from non-science. In 1935 and 1936, he took unpaid leave to go to the United Kingdom for a study visit.
