Scientist of the century
Leonhard Euler was the greatest scientist of the 18th century. So claims Ed Sandifer in this month's Physics World where he looks at the achievements of the gifted Swiss scientist, who was born 300 years ago this month on 15 April 1707.
In an illustrious career that saw him write over 800 books and papers on optics and mechanics, Euler earned part of the famous longitude prize to help sailors navigate at sea, designed the fountains for Frederick the Great's palace in Potsdam and developed ways to build lenses for microscopes and telescopes that yielded images undistorted by coloured rainbow-like fringes. Even in retirement, when he went blind, Euler continued to carry out research, calculating the orbit of Uranus and working out the buoyancy of hot-air balloons on the very day he died. (p. 35)
We are the physics WAGs
Anyone who watched last years football World Cup in Germany will have been shocked at how poorly the England team performed. Off the pitch, however, the wives and girlfriends of the England players excelled, with the acronym "WAG" being coined in the light of their antics, usually involving drinking and shopping to excess. Welcome now to the "physics WAGs" - non-scientists like Laura Phillips, a librarian at the University of Bristol, who are attached to a physicist. She has found plenty of reasons to enjoy living with a physicist, including having a life "that takes on new depth and meaning" and having someone who "can answer all your 'why' questions". But physicists are far from nerdy, Phillips points out. "Most of my boyfriend’s colleagues are cool, interesting, fun people," she says. (p. 24)Also in this issue:

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
