QUES: 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]

What is one modern gadget that benefits from high-power red LED lighting?

QUES: The interceptor aircraft (or simply interceptor) is a type of fighter aircraft designed specifically to intercept and destroy enemy aircraft, particularly bombers, usually relying on high speed and altitude capabilities. A number of jet interceptors such as the F-102 Delta Dagger, the F-106 Delta Dart, and the MiG-25 were built in the period starting after the end of World War II and ending in the late 1960s, when they became less important due to the shifting of the strategic bombing role to ICBMs. Invariably the type is differentiated from other fighter aircraft designs by higher speeds and shorter operating ranges, as well as much reduced ordnance payloads.

When were interceptors like the F-102 Delta Dagger first built?
What is the answer?
ANS: after the end of World War II
QUES: Western commentators post-9/11 often perceive madaris as places of radical revivalism with a connotation of anti-Americanism and radical extremism, frequently associated in the Western press with Wahhabi attitudes toward non-Muslims. In Arabic the word madrasa simply means "school" and does not imply a political or religious affiliation, radical or otherwise. Madaris have varied curricula, and are not all religious. Some madaris in India, for example, have a secularised identity. Although early madaris were founded primarily to gain "knowledge of God" they also taught subjects such as mathematics and poetry. For example, in the Ottoman Empire, "Madrasahs had seven categories of sciences that were taught, such as: styles of writing, oral sciences like the Arabic language, grammar, rhetoric, and history and intellectual sciences, such as logic." This is similar to the Western world, in which universities began as institutions of the Catholic church.

What type of teaching is provided at Indian madaris?
What is the answer?
ANS:
secularised
