Here’re some articles on advanced microscopy research, including quantum microscopy by coincidence. Not included (as yet) below is an article about nano fab of crystal lattices – direct deposition of individual atoms at lattice sites vs. more conventional doping (impurity) techniques. 1 . Studying ultrafast molecular dynamics • Phys.org > “Ultrafast X-ray spectroscopy: Watching molecules… Continue reading Imaging at the molecular and atomic level
Update July 11, 2022 Quantum advantage? – the long road ahead to making a useful quantum computer. • Wired > “Quantum Advantage Showdowns Have No Clear Winners” by Sophia Chen (July 11, 2022) – A series of recent experiments between quantum and classical computers shows the term’s ever-evolving meaning. Each claim of quantum advantage has… Continue reading Quantum computing explained – 5 levels of difficulty
As noted in comments for my “The future of (particle) physics?” post, the first results from Fermilab’s Muon g-2 experiment are a big deal for physics. Waiting for years. Highly anticipated. As expected, today these results were officially released. Fermilab itself released an excellent YouTube video visualization which includes background on the project and experiment… Continue reading Evidence for new physics? > Fermilab’s Muon g-2 results announced
Paraphrasing: Just a note before you go,A vision to be learnedTraveling near the speed of lightIt’s easy to get … Imagining how things would look when traveling near the speed of light is an interesting exercise. Using a freeware video game developed by MIT Game Lab (2012), this visualization (below) by The Action Lab is… Continue reading Sightseeing near the speed of light – realistic simulation
[Big Science, quantum foundations] While already following this Big Science project [1], with construction underway (for the next 3 years), I felt that a specific post was appropriate. The Deep Underground Neutrino Experiment (DUNE) is a massive worldwide collaboration between countries, organizations, and over a 1000 scientists. All hail neutrinos! [2] I spent some time… Continue reading DUNE – digging for neutrinos, not spice
While Sean Carroll’s latest chat-from-home presentations on his YouTube channel address the “biggest ideas” in the universe, other theoretical physicists explore whether our mind-boggling big universe has sort of a shelf life. A final reservation date, so to speak, at a fantastically socially-distanced restaurant at the end of the universe. Reference: Forbes > “What Will… Continue reading A shelf life for the universe?
[Communicating science series] While we’re all doing stay-at-home, theoretical physicist Sean Carroll created a chat-from-home series on his YouTube channel. Usually each informal talk (so not lecture-like organization) has a followup Q&A video. The Biggest Ideas in the Universe is a series of videos where I talk informally about some of the fundamental concepts that… Continue reading Biggest ideas in the universe – Sean Carroll chats concepts
I read more articles this past week about research on the proton. Some refined measurements. Some better insights into topics in quantum theory. Rather than add comments to related posts, I decided that a new post was appropriate. It struck me that the proton, as a composite particle (“particle” in the sense of an excitation… Continue reading Proton soup – a turbulent, dynamically complicated structure
As noted in my post on X-rays, looking beyond what our eyes can see – seeing what is hidden to visible light – tells a better cosmic story. Multi-wavelength observations refine and extend our view of the universe beyond our familiar vision. So, today we celebrate the Spitzer space telescope, one of NASA’s great space… Continue reading Celebrating Spitzer space telescope – seeing the invisible for 16 years
Who would have expected the Hubble Space Telescope (often referred to as HST or Hubble) to still be in operation after being launched into low Earth orbit in 1990? So, NASA/ESA kickstarted its 30th anniversary with some majestic galactic photos. Wiki: Five Space Shuttle missions have repaired, upgraded, and replaced systems on the telescope, including… Continue reading Celebrating Hubble – 30th anniversary year
