Context and question: Philosophy has become an increasingly academic discipline. More of its practitioners lament this situation than occurs with the sciences; nonetheless most new philosophical work appears in academic journals. Major philosophers through historyPlato, Aristotle, Socrates, Augustine, Descartes, Kierkegaard, Nietzschehave become as canonical as any writers. Some recent philosophy works are argued to merit the title "literature", but much of it does not, and some areas, such as logic, have become extremely technical to a degree similar to that of mathematics.
Besides Plato, Achilles, Socrates, and Augustine, who are other noted major philosophers in history?
Answer: unanswerable
Context and question: There are a number of proposals to redefine certain of the SI base units in terms of fundamental physical constants. This has already been done for the metre, which is defined in terms of a fixed value of the speed of light. The most urgent unit on the list for redefinition is the kilogram, whose value has been fixed for all science (since 1889) by the mass of a small cylinder of platinumiridium alloy kept in a vault just outside Paris. While nobody knows if the mass of the International Prototype Kilogram has changed since 1889 the value 1 kg of its mass expressed in kilograms is by definition unchanged and therein lies one of the problems it is known that over such a timescale the many similar PtIr alloy cylinders kept in national laboratories around the world, have changed their relative mass by several tens of parts per million, however carefully they are stored, and the more so the more they have been taken out and used as mass standards. A change of several tens of micrograms in one kilogram is equivalent to the current uncertainty in the value of the Planck constant in SI units.
Where is the top unit for the kilometer kept?
