Twelve PSI research highlights in 2025
Engineering skill and perseverance
Credit for the on-time completion of the major SLS 2.0 upgrade project is due in part to a team of dedicated electrical engineers.
Kelvin: The low-temperature scale
The art of engineering means, first of all, the skill required to design and manufacture devices that enable top technical performance. This gallery shows, in five pictures, that this term can also be understood differently if the devices are regarded as works of art with their very own aesthetic, apart from their actual function.
