Article: This idea was later developed in ancient philosophy by the Stoic school. Stoic epistemology generally emphasized that the mind starts blank, but acquires knowledge as the outside world is impressed upon it. The doxographer Aetius summarizes this view as "When a man is born, the Stoics say, he has the commanding part of his soul like a sheet of paper ready for writing upon." Later stoics, such as Sextus of Chaeronea, would continue this idea of empiricism in later Stoic writings as well. As Sextus contends "For every thought comes from sense-perception or not without sense-perception and either from direct experience or not without direct experience" (Against the Professors, 8.56-8).

Question: Where was Sextus from?
Ans: Chaeronea

Article: Religious humanism is an integration of humanist ethical philosophy with religious rituals and beliefs that centre on human needs, interests, and abilities. Though practitioners of religious humanism did not officially organise under the name of "humanism" until the late 19th and early 20th centuries, non-theistic religions paired with human-centred ethical philosophy have a long history. The Cult of Reason (French: Culte de la Raison) was a religion based on deism devised during the French Revolution by Jacques Hebert, Pierre Gaspard Chaumette and their supporters. In 1793 during the French Revolution, the cathedral Notre Dame de Paris was turned into a "Temple to Reason" and for a time Lady Liberty replaced the Virgin Mary on several altars. In the 1850s, Auguste Comte, the Father of Sociology, founded Positivism, a "religion of humanity". One of the earliest forerunners of contemporary chartered humanist organisations was the Humanistic Religious Association formed in 1853 in London. This early group was democratically organised, with male and female members participating in the election of the leadership and promoted knowledge of the sciences, philosophy, and the arts. The Ethical Culture movement was founded in 1876. The movement's founder, Felix Adler, a former member of the Free Religious Association, conceived of Ethical Culture as a new religion that would retain the ethical message at the heart of all religions. Ethical Culture was religious in the sense of playing a defining role in people's lives and addressing issues of ultimate concern.

Question: During what time was a religious state replaced in the Notre Dame cathedral with a symbol of Humanism?
Ans: 1793

Article: In the late 1980s, key breakthroughs in GaN epitaxial growth and p-type doping ushered in the modern era of GaN-based optoelectronic devices. Building upon this foundation, Dr. Moustakas at Boston University patented a method for producing high-brightness blue LEDs using a new two-step process. Two years later, in 1993, high-brightness blue LEDs were demonstrated again by Shuji Nakamura of Nichia Corporation using a gallium nitride growth process similar to Dr. Moustakas's. Both Dr. Moustakas and Mr. Nakamura were issued separate patents, which confused the issue of who was the original inventor (partly because although Dr. Moustakas invented his first, Dr. Nakamura filed first).[citation needed] This new development revolutionized LED lighting, making high-power blue light sources practical, leading to the development of technologies like BlueRay, as well as allowing the bright high resolution screens of modern tablets and phones.[citation needed]

Question: What is one modern gadget that benefits from high-power blue LED lighting?
Ans: tablets

Article: During the earlier medieval period, the vocal music from the liturgical genre, predominantly Gregorian chant, was monophonic, using a single, unaccompanied vocal melody line. Polyphonic vocal genres, which used multiple independent vocal melodies, began to develop during the high medieval era, becoming prevalent by the later 13th and early 14th century.

Question: When did the Polyphonic vocal genre begin to develop?
Ans:
during the high medieval era
