What’s Shaking

The Raspberry Shake is not a new type of smoothie, but a new tool for detecting earthquakes and other seismic activity. Developed by a startup in Panama, the Raspberry shake is a powerful tool for people interested in earthquakes and citizen science. The Raspberry Shake, designed initially as a maker project for home use, has… Continue reading What’s Shaking

The Beaufort Scale

Talking about the weather is usually a sign of conversational desperation and that is particularly true in California. The weather patterns here are fairly regular and predictable. Recently, however, a long series of very stormy and rainy weather has buffeted California. Watching the trees bend and sway in the gusty winds reminded me of the… Continue reading The Beaufort Scale

Youth Robotics

            Robotics is not only the province of Silicon Valley high-tech start-ups or university engineering grad students. Inventor Dean Kamen founded FIRST as an organization to encourage young people to get involved in STEM activities to prepare for a technology-rich future. FIRST (For Inspiration and Recognition of Science and Technology) aims to combine the excitement… Continue reading Youth Robotics

New Vistas

The James Webb Space Telescope The James Webb Space Telescope(JWST) has to count as one of the greatest advances in science in 2022. NASA’s giant infrared observatory in the sky is now sending images back to earth. This new perspective on the cosmos revealed unprecedented detail of distant galaxies and the far reaches of space,… Continue reading New Vistas

Winter Solstice

Winter holidays in many cultures originated as ancient people observed the changes in the sun’s height in the sky and the corresponding length of the day. Every day for the past six months the Sun has been lower in the sky and there have been fewer hours of daylight. This past Wednesday, December 21st, the… Continue reading Winter Solstice

Nanotechnology

Big Things from Small Particles Nanotechnology is a branch of science and technology focused on the study and application of tiny particles and structures. This interdisciplinary field combines many areas of study, such as physics, chemistry, biology, materials science, engineering, and computer science. One example of nanotechnology at work is Tethys, the device developed by… Continue reading Nanotechnology

Dragonfly Robot

Nanotechnology Nanotechnology is the science, engineering, and technology at the molecular level, which is about 1 to 100 nanometers.  At Duke University, bio-medical engineers have created a robot shaped like a dragonfly with a soft body that operates without electronics. This miniature robot is driven by air pressure through microchannels in its hydrogel body. DraBot, as… Continue reading Dragonfly Robot

A New Hot Jupiter

Discovering Exoplanet TOI-2109b Looking out my west-facing bedroom window on a clear, dark night, I see hundreds of stars, each just a point of light. Many of those stars may be like our sun with a system of orbiting planets. We’ve long suspected that other suns have other planets. Back in 1979, Gordon Walker began… Continue reading A New Hot Jupiter
