QUES: IBM has 12 research laboratories worldwide, bundled into IBM Research. As of 2013[update] the company held the record for most patents generated by a business for 22 consecutive years. Its employees have garnered five Nobel Prizes, six Turing Awards, ten National Medals of Technology and five National Medals of Science. Notable company inventions or developments include the automated teller machine (ATM), the floppy disk, the hard disk drive, the magnetic stripe card, the relational database, the Universal Product Code (UPC), the financial swap, the Fortran programming language, SABRE airline reservation system, dynamic random-access memory (DRAM), copper wiring in semiconductors, the silicon-on-insulator (SOI) semiconductor manufacturing process, and Watson artificial intelligence.

How many Nobel Prizes have been won by IBM employees?

QUES: Feynman has been called the "Great Explainer". He gained a reputation for taking great care when giving explanations to his students and for making it a moral duty to make the topic accessible. His guiding principle was that, if a topic could not be explained in a freshman lecture, it was not yet fully understood. Feynman gained great pleasure from coming up with such a "freshman-level" explanation, for example, of the connection between spin and statistics. What he said was that groups of particles with spin "repel", whereas groups with integer spin "clump". This was a brilliantly simplified way of demonstrating how FermiDirac statistics and BoseEinstein statistics evolved as a consequence of studying how fermions and bosons behave under a rotation of 360. This was also a question he pondered in his more advanced lectures, and to which he demonstrated the solution in the 1986 Dirac memorial lecture. In the same lecture, he further explained that antiparticles must exist, for if particles had only positive energies, they would not be restricted to a so-called "light cone".

Antiparticles had to exist because if particles only were of positive energy, they would not be in what?
What is the answer?
ANS: light cone
QUES: In 1374 King Louis of Hungary approved the Privilege of Koszyce (Polish: "przywilej koszycki" or "ugoda koszycka") in Kosice in order to guarantee the Polish throne for his daughter Jadwiga. He broadened the definition of who was a member of the nobility and exempted the entire class from all but one tax (anowy, which was limited to 2 grosze from an (an old measure of land size)). In addition, the King's right to raise taxes was abolished; no new taxes could be raised without the agreement of the nobility. Henceforth, also, district offices (Polish: "urzedy ziemskie") were reserved exclusively for local nobility, as the Privilege of Koszyce forbade the king to grant official posts and major Polish castles to foreign knights. Finally, this privilege obliged the King to pay indemnities to nobles injured or taken captive during a war outside Polish borders.

What did king louis of hungary do for the nobles?
