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
Heike Kamerlingh Onnes helium, using several precooling stages and the Hampson–Linde cycle based on the Joule–Thomson effect. This way he lowered the temperature to the boiling point of helium (−269 °C, 4.2 K). By reducing the pressure of the liquid helium he achieved a temperature near 1.5 K. These were the coldest temperatures achieved on earth at the time. The equipment employed is at the Boerhaave Museum in Leiden. In 1911 Kamerlingh Onnes measured the electrical conductivity of pure metals (mercury, and later tin and lead) at very low temperatures. Some scientists, such as William Thomson (Lord Kelvin), believed that electrons flowing through
