Can you guess what I found while rearranging my closet shelves today? It’s also known as the gadget I spent several hours playing with (wasting time?) today. #ScienceRocks #ElectromagneticWaves

The sky is so beautiful as I head home after the first time teaching Science Explorers since March 2020. Today, volcanoes! #sciencerocks @scienceexplorers

I believe in #Science! 2 weeks post-op. Surgeon’s happy with the healing of the incisions & keeping me in the neck brace another 4 weeks. I’m now using a bone stimulator brace for 4 hours a day to help all of the titanium set into the bone more firmly. Can’t lift anything over 5 pounds or raise my arms higher than my chest, but #Progress. 😊 #ScienceRocks #RestoreOrthopedics #DrSSamuelBiederman (at Restore Orthopedics and Spine Center)

Deep-sea geology rocks!
Mud collected from the deep seafloor is helping scientists from MBARI and the United States Geological Survey (USGS)
understand the geologic history of the Cascadia Subduction Zone off the coast of Oregon. Sediment cores collected by ROV Doc Ricketts reveal layers formed over thousands of years. Here, the Juan de Fuca tectonic plate is thrust beneath North America, leading to a buildup of friction. The massive release of energy when friction gives way results in megathrust earthquakes and tsunamis.
The team is also getting a closer look at the biology of this dynamic region. These cores help our scientists look back in time to see when these geologic events have happened in the past and the natural processes that shape the continental margin to help Pacific Coast communities plan for the future.

September is spider season around here! The absolute best spider webs of the year. Plus, the added joy of walking face first into them in the dark. #Nature #ScienceRocks

Researchers at ETH Zurich have succeeded in observing a crystal that consists only of electrons. Such Wigner crystals were already predicted almost ninety years ago but could only now be observed directly in a semiconductor material.
For several decades, however, this prediction remained purely theoretical, as those “Wigner crystals” can only form under extreme conditions such as low temperatures and a very small number of free electrons in the material. This is in part because electrons are many thousands of times lighter than atoms, which means that their motional energy in a regular arrangement is typically much larger than the electrostatic energy due to the interaction between the electrons.
Using a trick, the physicists managed to make the regular arrangement of the electrons visible despite that small separation in the crystal lattice. To do so, they used light of a particular frequency to excite so-called excitons in the semiconductor layer. Excitons are pairs of electrons and “holes” that result from a missing electron in an energy level of the material. The precise light frequency for the creation of such excitons and the speed at which they move depend both on the properties of the material and on the interaction with other electrons in the material – with a Wigner crystal, for instance.
In contrast to previous experiments based on planar semiconductors, in which Wigner crystals were observed indirectly through current measurements, this is a direct confirmation of the regular arrangement of the electrons in the crystal. In the future, with their new method Imamoğlu and his colleagues hope to investigate exactly how Wigner crystals form out of a disordered “liquid” of electrons.

💜 The gem that started it all for me. In 1992 our school had a science day. We tried to tug a preserved cow heart apart, we learned about electricity and we got to mine for stones~ The organizers couldn’t believe I had found such a large chevron amethyst in the dig. Their excitement and the thrill of the find was overwhelming in such a positive way. Little did my teachers know the love and passion they instilled that day! 🔮 If you have or know little ones, nuture their magic. Nourish their minds with beautiful ways to live and be themselves. The world is a harsh place and there is so much room to love and grow. We can pay it forward to them by showing them good ways to live, to act, to respond. I can’t even count the ways, as the list can endlessly go on and on. The youth is the future! Shifts happen every day. Share your insights with them. Let’s leave this place better than we found it .°• #grateful #sacredspaces #expandthemindsofchildren #theyouthithefuture #sciencerocks
