Scientific reasoning requires the irrationality of intuition
Research
EPFL
EPFL Summer Series: How science works. Science is based on coherent reasoning, while intuition follows a more disjointed path. But scientific research couldn’t succeed if scientists didn’t listen to their gut feelings every once in a while.
First light at Furka: The experiments can begin
Research
PSI
It's another milestone on the path to full operation of the X-ray free-electron laser SwissFEL with five experiment stations in all: "First light" at the experiment station Furka. It clears the way for experimental possibilities that are unique worldwide. Team leader Elia Razzoli explains what the Furka Group is planning to do.
Running quantum software on a classical computer
Research
EPFL
Two physicists, from EPFL and Columbia University, have introduced an approach for simulating the quantum approximate optimization algorithm using a traditional computer. Instead of running the algorithm on advanced quantum processors, the new approach uses a classical machine-learning algorithm that closely mimics the behavior of near-term quantum computers.
High-precision frequency measurement
Research
ETH Zurich
Many scientific experiments require highly precise time measurements with the help of a clearly defined frequency. Now, a new approach allows the direct comparison of frequency measurements in the lab with the atomic clock in Bern, Switzerland.
On eternal imbalance
Research
ETH Zurich
Some physical systems, especially in the quantum world, do not reach a stable equilibrium even after a long time. An ETH researcher has now found an elegant explanation for this phenomenon.
The anatomy of a planet
Research
ETH Zurich
Researchers at ETH Zurich working together with an international team have been able to use seismic data to look inside Mars for the first time. They measured the crust, mantle and core and narrowed down their composition. The three resulting articles are being published together as a cover story in the journal Science.
