Nobel Prize-winning Swedish electrical engineer Hannes Alfvén is best remembered for his research on plasma physics. He practically pioneered the field of magnetohydrodynamics, which deals with plasmas in magnetic fields. He also proposed the concept of plasma cosmology, challenging the big-bang model, and penned works such as Cosmic Plasma.

Swedish physicist and astronaut Christer Fuglesang scripted history as the first Swedish to go to space. He has had an 18-year stint as an ESA astronaut and has also taught math, particle physics, and space physics. A PhD from Stockholm University, he has also worked with CERN.
Gustaf Dalén was an industrialist, engineer, and inventor. The AGA cooker and the Dalén light are among his most prominent inventions. He was a long-term CEO of the AGA company. He received over 100 patents during his lifetime. He received the Nobel Prize in Physics in 1912 for his invention of a special kind of automatic regulator.
Renowned Swedish physicist Johannes Rydberg is most recognised for devising the Rydberg formula, a mathematical formula used to determine the wavelengths of photons. He was twice nominated for the Nobel Prize and was inducted as a Fellow of the Royal Society in 1919. He worked at the Lund University as a provisional professor of physics before becoming a full professor.
