Physicists Discover Previously Unknown Crystal Forged During Manhattan Project's Trinity Test

An unusual crystal created by America’s first nuclear bomb test could help scientists understand a structure needed for quantum computers, solar power, and batteries.

Lately I've been "playing" with https://store.steampowered.com/app/4055380 - the neat thing; it comes with native Linux binaries!

SpaceSim - Astrophysical Simulation Software on Steam

Simulation & rendering software that uses Smoothed Particle Hydrodynamics (SPH) to simulate collisions of celestial bodies, accretion disks around black holes, or formation of galaxies in the early universe.

Aha! Conclusion, effort is a lot less walking uphill than cycling uphill. (which answer my question).

Hmm, is biking vs. walking more efficient or less efficient on steep UPHILL? (I know bicycling wins absolutely on flats and downhill). I would guess, walking is more efficient? #energy #physics #BikeTooter
#SpeedOfLight The expansion speed of the universe is described by the Hubble constant, named after astronomer Edwin Hubble, its discoverer. #physics

A brief history of the cosmic distance record The cosmic distance record has grown, in just a few hundred years, from millions of light-years to over 30 billion light-years. Here's a look back at our history of ever-receding horizons. bigthink.com/starts-with-... #space #astro #physics #telescope

Only nearby objects appear to the naked eye. With telescopes of all types, especially in space, we've smashed those records many times over.

Liquid Pulleys and Gears

In mechanical systems, gears and pulleys transmit rotation from one location to another. Here, researchers explore a fluid dynamical version of such systems. The set-up consists of two rotors contained in a cylindrical corral filled with a water-glycerin mixture. One of the rotors is active, marked here with orange; the other (blue) one is passive, meaning that it can rotate due to the forces on it but it is not actively driven by a motor.

The three flow visualizations illustrate different configurations the rotors can take on, depending on their separation distance. In the top image, the rotors have a moderate separation distance and the passive one rotates opposite of the active one. That rotation direction is set by the high-shear flow on its inner side. If the rotors are close together (left image), they rotate in the same direction, aided by strong shear on the outside edge of the passive rotor; this mimics being linked with a belt. And, finally, if the rotors are widely separated, they also corotate, with the fluid in between acting like a virtual gear linking them. (Image credit: J. Smith et al.)

🔋⚖️ Storing #energy in a #battery increases the total energy of the system, which according to #physics, results in a proportional increase in mass.

For a standard #smartphone, this added weight is roughly equivalent to one-quadrillionth of a gram. The change is the result of energy being stored in the chemical bonds of the lithium-ion cells during the charging process.
