Largest primeA research team at Central Missouri State University (USA) has identified the largest known prime number. Associate dean Steven Boone and mathematics professor Curtis Cooper found the largest number – a positive number divisible by only itself and 1, 2, 3, 5, 7 and so on .
after programming 700 computers years ago. The number that the team found is 9.1 million digits long. It is a Mersenne prime known as M30402457, which is 2 to the 30,402,457th power minus 1. Mersenne primes are a special category expressed as 2 to the ‘p’ power minus 1, in which ‘p’ also is a prime number. “We’re super excited,” said Boone, a chemistry professor. “We’ve been looking for such a number for a long time.” The discovery is affiliated with the Great Internet Mersenne Prime Search, a global contest using volunteers who run software that searches for the largest Mersenne prime.
Trail
The University of Twente and Radboud University Nijmegen have joined Trail, a research school for Transport, Infrastructure and Logistics. Seven TU Delft faculties also work as part of Trail, together with four faculties from Erasmus University Rotterdam and the one faculty from University of Groningen. The University of Twente’s research group ‘Traffic, Transport and Space’, and Radboud University’s group ‘Spatial Planning, Institutions and Mobility, will participate in Trail.
Delft Blauw
234,000 Dutch TV viewers tuned in to watch the first broadcast of the reality TV series, Delft Blauw, which follows the lives of ten TU Delft students in the student house Markt 9. In the first broadcast, viewers watched as the residents cleaned the toilets and discussed a new common living room in the house. The two teams of students then had to come up with ideas for the mobile phone of the future. The winning team’s idea was for a malleable telephone.
US delegation
Following the destructive floods in New Orleans caused by Hurricane Katrina, officials in the US are exploring new ideas for a system to prevent such a tragedy occurring again. In order to gain greater knowledge of what the Netherlands does to prevent flooding, a delegation of business leaders and politicians from the State of Louisiana are visiting the Netherlands. The US delegation will visit TU Delft’s WL Hydraulics and Delft’s Higher Water Authority and will tour the canals. In Delft, they the problems with water in the city will be discussed. The governor of Louisiana, Kathleen Blanco, and US Senators Mary Landrieu and David Vitter will be part of the delegation. The US delegation was invited to the Netherlands by Dutch Undersecretary of Traffic and Water, Melanie Schultz van Haegen. During their week-long stay in the Netherlands, the Americans will also meet Crown Prince Willem Alexander and Dutch Minister Laurens Jan Brinkhorst.
Pavilion
Five teams are competing to design the new Stylos Pavilion. The teams ideas for a new Pavilion are as follows: ‘Pavilion 30’ designed by Jeroen Jochems and Sven Jaspers is an ‘organic blob-form’; ‘Fundamentum’ by Bobby Boc has a ‘removable bamboo facade’; ‘Tubo’ by Jeroen Spee and Jeroen Steenvoorden is constructed of sewer pipes; ‘Black box’ by Philip Mannaerts and Martijn de Geus uses coconut fiber plates; and ‘By cycle’ by Tom van de Putte and Sander Rutgers is an integrated bicycle stall.
