Superconductivity a better environmental performance but could also improve public acceptance for expansion of the electric grid. Superconductivity Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic flux fields occurring in certain materials, called superconductors, when cooled below a characteristic critical temperature. It was discovered by Dutch physicist Heike Kamerlingh Onnes on April 8, 1911, in Leiden. Like ferromagnetism and atomic spectral lines, superconductivity is a quantum mechanical phenomenon. It is characterized by the Meissner effect, the complete ejection of magnetic field lines from the interior of the superconductor during its transitions into the superconducting state. The
Groningen back to 1614. After the University of Leiden, it is the second oldest Dutch university. The university educated the first female student, Aletta Jacobs, the first Dutch national astronaut, Wubbo Ockels, the first president of the European Central Bank, Wim Duisenberg and two Nobel prize winners, Heike Kamerlingh Onnes and Ben Feringa. 200,000 people were either students, teachers or researchers at the university. Groningen has the highest percentage of students by total population, approximately 25 percent. The city council has 39 members. With 9 seats, the social-liberal D66 is the largest party on the council. The social-democratic PvdA has 6
