Problem: Alternative proposals for the etymology of *Slovenin propounded by some scholars have much less support. Lozinski argues that the word *slava once had the meaning of worshipper, in this context meaning "practicer of a common Slavic religion," and from that evolved into an ethnonym. S.B. Bernstein speculates that it derives from a reconstructed Proto-Indo-European *(s)lawos, cognate to Ancient Greek laos "population, people," which itself has no commonly accepted etymology. Meanwhile, others have pointed out that the suffix -enin indicates a man from a certain place, which in this case should be a place called Slova or Slava, possibly a river name. The Old East Slavic Slavuta for the Dnieper River was argued by Henrich Bartek (19071986) to be derived from slova and also the origin of Slovene.
When did Bartek argue the Dnieper River was the origin of Slovene?

Problem: The differential analyser, a mechanical analog computer designed to solve differential equations by integration, used wheel-and-disc mechanisms to perform the integration. In 1876 Lord Kelvin had already discussed the possible construction of such calculators, but he had been stymied by the limited output torque of the ball-and-disk integrators. In a differential analyzer, the output of one integrator drove the input of the next integrator, or a graphing output. The torque amplifier was the advance that allowed these machines to work. Starting in the 1920s, Vannevar Bush and others developed mechanical differential analyzers.
In the 1920s, who was the person who developed mechanical differential analyzers?

Answer:
Vannevar Bush
