Problem: Karl Popper:

As early as 1934, Popper wrote of the search for truth as "one of the strongest motives for scientific discovery." Still, he describes in Objective Knowledge (1972) early concerns about the much-criticised notion of truth as correspondence. Then came the semantic theory of truth formulated by the logician Alfred Tarski and published in 1933. Popper writes of learning in 1935 of the consequences of Tarski's theory, to his intense joy. The theory met critical objections to truth as correspondence and thereby rehabilitated it. The theory also seemed, in Popper's eyes, to support metaphysical realism and the regulative idea of a search for truth.

What did Tarski write about the search for truth in 1934?

Problem: Pain is the most common reason for people to use complementary and alternative medicine. An analysis of the 13 highest quality studies of pain treatment with acupuncture, published in January 2009, concluded there is little difference in the effect of real, sham and no acupuncture. However other reviews have found benefit. Additionally, there is tentative evidence for a few herbal medicine. There is interest in the relationship between vitamin D and pain, but the evidence so far from controlled trials for such a relationship, other than in osteomalacia, is unconvincing.
What did an analysis of the 13 studies of pain treatment conclude about the effect of real treament versus sham treatments?

Answer: little difference in the effect

Context and question: In testimony before the Senate Committee on Commerce, Science, and Transportation on June 3, 2008, former director of the CFTC Division of Trading & Markets (responsible for enforcement) Michael Greenberger specifically named the Atlanta-based IntercontinentalExchange, founded by Goldman Sachs, Morgan Stanley and BP as playing a key role in speculative run-up of oil futures prices traded off the regulated futures exchanges in London and New York.

Mr Greenberger was later corrected on this matter.

Question: Despite the position of the official organizations, an opinion poll carried out between 2001 and 2004 showed that the majority of the Valencian people consider Valencian different from Catalan. This position is promoted by people who do not use Valencian regularly. Furthermore, the data indicates that younger generations educated in Valencian are much less likely to hold these views. A minority of Valencian scholars active in fields other than linguistics defends the position of the Royal Academy of Valencian Culture (Acadèmia de Cultura Valenciana, RACV), which uses for Valencian a standard independent from Catalan.
Is there an answer to this question: How many scholars outside of linguistics agree with the Royal Academy?

Answer: A minority


Problem: Materialism:

In Ancient Indian philosophy, materialism developed around 600 BC with the works of Ajita Kesakambali, Payasi, Kanada, and the proponents of the Cārvāka school of philosophy. Kanada became one of the early proponents of atomism. The Nyaya–Vaisesika school (600 BC - 100 BC) developed one of the earliest forms of atomism, though their proofs of God and their positing that the consciousness was not material precludes labelling them as materialists. Buddhist atomism and the Jaina school continued the atomic tradition.

Around what time did materialism become part of Ancient Indian philosophy?

A:
600 BC
