QUES: Ancient and medieval Hindu texts identify six pramanas as correct means of accurate knowledge and truths: pratyaksa (perception), anumana (inference), upamana (comparison and analogy), arthapatti (postulation, derivation from circumstances), anupalabdi (non-perception, negative/cognitive proof) and sabda (word, testimony of past or present reliable experts) Each of these are further categorized in terms of conditionality, completeness, confidence and possibility of error, by each school . The various schools vary on how many of these six are valid paths of knowledge. For example, the Carvaka nastika philosophy holds that only one (perception) is an epistemically reliable means of knowledge, the Samkhya school holds three are (perception, inference and testimony), while the Mimamsa and Advaita schools hold all six are epistemically useful and reliable means to knowledge.
Which school believes only postulation is a valid form of knowledge?

QUES: In manufacturing the glass bulb, a type of "ribbon machine" is used. A continuous ribbon of glass is passed along a conveyor belt, heated in a furnace, and then blown by precisely aligned air nozzles through holes in the conveyor belt into molds. Thus the glass bulbs are created. After the bulbs are blown, and cooled, they are cut off the ribbon machine; a typical machine of this sort produces 50,000 bulbs per hour. The filament and its supports are assembled on a glass stem, which is fused to the bulb. The air is pumped out of the bulb, and the evacuation tube in the stem press is sealed by a flame. The bulb is then inserted into the lamp base, and the whole assembly tested.
How is the filament attached to the bulb?

ANS: assembled on a glass stem, which is fused to the bulb
