Jacob Holm was flipping through proofs from an October 2019 research paper he and colleague Eva Rotenberg an associate professor in the department of applied mathematics and computer science at the Technical University of Denmark had published online, when he discovered their findings had unwittingly given away a solution to a centuries-old graph problem.
Holm, an assistant professor of computer science at the University of Copenhagen, was relieved no one had caught the solution first. “It was a real ‘Eureka!’ moment,” he says. “It suddenly seemed obvious.”
Holm and Rotenberg were trying to find a shortcut for determining whether a graph is “planar” that is, if it could be drawn flat on a surface without any of its lines crossing each other (flat drawings of a graph are also called “embeddings”).

Energy systems of tomorrow to be developed in giant lab
DTU’s energy laboratory at Risø Campus is now being expanded, so that researchers and development departments in the energy industry can test the sustainable energy systems of the future in an even more realistic setup.
Large fields with sun-tracking solar cells. Offshore wind turbines that can produce both electricity and hydrogen. Electric cars that recharge electricity, but returns it to the power grid when needed. These are some of the building blocks for the connected energy systems of the future. Added to this is an interconnection of electricity, heating and hydrogen systems for optimal utilization of renewable energy.

John Ling’s invitation to the fifth in EIPC’s series of Technical Snapshots was as droll as we have come to expect: “In these confined days of lockdown, and exhortations to stay at home and only go out for exercise, this only exercises the natural inclination to hop on a ‘plane to some sunshine.’ Although not the same as Factor 20, one of our webinars gives a high degree of protection from harmful ignorance, and you do not have to go out in the cold.”
Cleanliness was the focus of this informative and enlightening event on Feb. 17, 2021, introduced by EIPC technical director Tarja Rapala-Virtanen and moderated by EIPC board member Christian Behrendt, CEO of German PCB fabricator ILFA.
