Delft University of Technology Iranian Election Protests. The biggest number of international students studies at Aerospace Engineering and Electrical Engineering, Mathematics, and Computer Science departments. Currently TU Delft is a home to 437 faculty, with more than 3,375 academic staff. The responsibility of TU Delft professors is lecturing, guiding undergraduate and graduate students, as well as performing original research in their respective fields. Many notable people were TU Delft faculty. In science, Heike Kamerlingh Onnes, a 1913 Nobel Laureate in physics, a discoverer of superconductivity, was a former TU Delft faculty member, working as an assistant to Johannes Bosscha. Discoverer of the Prins reaction
History of superconductivity has a boiling point of 4.2 kelvins at atmospheric pressure. Heike Kamerlingh Onnes and Jacob Clay reinvestigated Dewar's earlier experiments on the reduction of resistance at low temperatures. Onnes began the investigations with platinum and gold, replacing these later with mercury (a more readily refinable material). Onnes's research into the resistivity of solid mercury at cryogenic temperatures was accomplished by using liquid helium as a refrigerant. On April 8, 1911, 16:00 hours Onnes noted "Kwik nagenoeg nul", which translates as "[Resistance of] mercury almost zero." At the temperature of 4.19 K, he observed that the resistivity abruptly disappeared (the measuring
