Question: In response to the early-to-mid-17th century "continental rationalism" John Locke (1632–1704) proposed in An Essay Concerning Human Understanding (1689) a very influential view wherein the only knowledge humans can have is a posteriori, i.e., based upon experience. Locke is famously attributed with holding the proposition that the human mind is a tabula rasa, a "blank tablet", in Locke's words "white paper", on which the experiences derived from sense impressions as a person's life proceeds are written. There are two sources of our ideas: sensation and reflection. In both cases, a distinction is made between simple and complex ideas. The former are unanalysable, and are broken down into primary and secondary qualities. Primary qualities are essential for the object in question to be what it is. Without specific primary qualities, an object would not be what it is. For example, an apple is an apple because of the arrangement of its atomic structure. If an apple was structured differently, it would cease to be an apple. Secondary qualities are the sensory information we can perceive from its primary qualities. For example, an apple can be perceived in various colours, sizes, and textures but it is still identified as an apple. Therefore, its primary qualities dictate what the object essentially is, while its secondary qualities define its attributes. Complex ideas combine simple ones, and divide into substances, modes, and relations. According to Locke, our knowledge of things is a perception of ideas that are in accordance or discordance with each other, which is very different from the quest for certainty of Descartes.

Answer: John Locke


Question: Richard Sander claims that by artificially elevating minority students into schools they otherwise would not be capable of attending, this discourages them and tends to engender failure and high dropout rates for these students. For example, about half of black college students rank in the bottom 20 percent of their classes, black law school graduates are four times as likely to fail bar exams as are whites, and interracial friendships are more likely to form among students with relatively similar levels of academic preparation; thus, blacks and Hispanics are more socially integrated on campuses where they are less academically mismatched. He claims that the supposed "beneficiaries" of affirmative action – minorities – do not actually benefit and rather are harmed by the policy. Sander's claims have been disputed, and his empirical analyses have been subject to substantial criticism. A group including some of the country's lead statistical methodologists told the Supreme Court that Sander's analyses were sufficiently flawed that the Court would be wise to ignore them entirely. At the same time many scholars have found that minorities gain substantially from affirmative action.
Is there an answer to this question: Where do half of the white college students rank in terms of their performance relative to the rest of their class?

Answer: unanswerable


Question: After the capital of India moved to Delhi, a temporary secretariat building was constructed in a few months in 1912 in North Delhi. Most of the government offices of the new capital moved here from the 'Old secretariat' in Old Delhi (the building now houses the Delhi Legislative Assembly), a decade before the new capital was inaugurated in 1931. Many employees were brought into the new capital from distant parts of India, including the Bengal Presidency and Madras Presidency. Subsequently housing for them was developed around Gole Market area in the 1920s. Built in the 1940s, to house government employees, with bungalows for senior officials in the nearby Lodhi Estate area, Lodhi colony near historic Lodhi Gardens, was the last residential areas built by the British Raj.
Is there an answer to this question: What was the name of the last residential area built by the British Raj?

Answer: Lodhi colony


Question: This method involves coating LEDs of one color (mostly blue LEDs made of InGaN) with phosphors of different colors to form white light; the resultant LEDs are called phosphor-based or phosphor-converted white LEDs (pcLEDs). A fraction of the blue light undergoes the Stokes shift being transformed from shorter wavelengths to longer. Depending on the color of the original LED, phosphors of different colors can be employed. If several phosphor layers of distinct colors are applied, the emitted spectrum is broadened, effectively raising the color rendering index (CRI) value of a given LED.
Is there an answer to this question: What shift does blue light undergo in the pcLEDs method?

Answer:
Stokes
