All-optical method sets record for ultrafast high-spatial-resolution imaging: 15 trillion frames per second

“New all-optical imaging technique with an unprecedented frame rate allows scientists to visualize ultrafast transient phenomena High-speed cameras can take pictures in quick succession. This makes them useful for visualizing ultrafast dynamic phenomena, such as femtosecond laser ablation for precise …

Astronomers discover an Earth-sized “pi planet” with a 3.14-day orbit

“The rocky world, with its baking-hot surface, is likely not habitable. In a delightful alignment of astronomy and mathematics, scientists at MIT and elsewhere have discovered a “pi Earth” — an Earth-sized planet that zips around its star every 3.14 …

Customising an electronic material

“PSI scientists have gained a fundamental understanding of a highly promising material that could be suited to future data storage applications. Their experiments with strontium-iridium oxide, Sr2IrO4, investigated both the magnetic and electronic properties of the material as a thin …

Defying a 150-year-old rule for phase behavior

“Frozen water can take on up to three forms at the same time when it melts: liquid, ice and gas. This principle, which states that many substances can occur in up to three phases simultaneously, was explained 150 years ago …

Digital Level With Cross-Line Laser

“Hi everyone, today I’m going to show you how to make a digital level with optional integrated cross-line laser. About a year ago I created a digital multi-tool. While that tool does feature a lot of different modes, for …

Discovery: User Manual of the Oldest Surviving Computer in the World

“The Zuse Z4 is considered the oldest preserved computer in the world. Manufactured in 1945 and overhauled and expanded in 1949/1950, the relay machine was in operation on loan at the ETH Zurich from 1950 to 1955. Today the …

DIY Multifunction Energy Meter V2.0

“In this Instructable, I will show you how to make a Wemos ( ESP8266 ) based Multifunction Energy Meter. This little Meter is a very useful device that monitors voltage, current, power, energy, and capacity. Apart from these it also monitors the …

Dresden Physicists Develop Printable Organic Transistors

“Scientists at the Institute of Applied Physics at TU Dresden have come a step closer to the vision of a broad application of flexible, printable electronics. The team around Dr Hans Kleemann has succeeded for the first time in developing …

Engineers produce a fisheye lens that’s completely flat

“The single piece of glass produces crisp panoramic images. To capture panoramic views in a single shot, photographers typically use fisheye lenses — ultra-wide-angle lenses made from multiple pieces of curved glass, which distort incoming light to produce wide, bubble-like images …

Greek Vocabulary Reviewer

“Greek language vocabulary reviewer via an interactive panel game with arcade pushbuttons, LCD screens, LEDs and more. This project involves creating an interactive panel game with Arduino components to help review Greek vocabulary in a fun way that feels similar …
