Liquid metal may point way to wearable ultrasound devices

The best-known byproduct of ultrasound—so named because its frequencies exceed the range of the human ear—is, in fact, not audio but visual: 2D imagery, often of a fetus maturing in the womb. But ultrasound has also found ...

New algorithm unlocks high-resolution insights for computer vision

Imagine yourself glancing at a busy street for a few moments, then trying to sketch the scene you saw from memory. Most people could draw the rough positions of the major objects like cars, people, and crosswalks, but almost ...

Engineers use moisture to pull carbon dioxide out of the air

In a corner of Kelsey Hatzell's lab sits a small jar filled with a material that has an ability far beyond what its nondescript appearance would suggest: a way to capture and release carbon dioxide from the atmosphere by ...

A quadrupedal robot can do parkour and walk across rubble

The robot known as ANYmal has, for some time, had no problem coping with the stony terrain of Swiss hiking trails. Now researchers at ETH Zurich have taught this quadrupedal robot some new skills: It is proving rather adept ...

Engineer

An engineer is a professional practitioner of engineering, concerned with applying scientific knowledge, mathematics and ingenuity to develop solutions for technical problems. Engineers design materials, structures, machines and systems while considering the limitations imposed by practicality, safety and cost. The word engineer is derived from the Latin roots ingeniare ("to contrive, devise") and ingenium ("cleverness").

Engineers are grounded in applied sciences, and their work in research and development is distinct from the basic research focus of scientists. The work of engineers forms the link between scientific discoveries and their subsequent applications to human needs.
