> Chua in his 1971 paper identified a theoretical symmetry between the non-linear #resistor (voltage vs. current), non-linear #capacitor (voltage vs. charge), and non-linear #inductor (magnetic flux linkage vs. current). From this #symmetry he inferred the characteristics of a fourth fundamental non-linear circuit element, linking magnetic flux and charge, which he called the #memristor. In contrast to a linear (or non-linear) resistor the memristor has a dynamic relationship between current and voltage including a #memory of past voltages or currents.

> The #Laser #Interferometer Gravitational-Wave Observatory (LIGO) is a huge installation measured in kilometers that is listening for wrinkles in space-time.

> Gravity causes #space-time to stretch — think back to the diagrams you’ve seen of a massive orb (a star or planet) sitting on a plane with grid lines drawn on it, the fabric of that plane being stretch downward from the mass of the orb. If you have two massive entities like black holes orbiting each other, they give off #gravitational #waves. When they collide and merge, they create a brief but very strong train of waves. Evidence of these events are what #LIGO is looking for.

> "Instead of computation, we're putting the computer to work as a new experimental platform to realize and detect new phases of matter."
> "Time-crystals are a striking example of a new type of non-equilibrium quantum phase of matter," says Khemani.
"While much of our understanding of condensed matter physics is based on equilibrium systems, these new quantum devices are providing us a fascinating window into new non-equilibrium regimes in many-body physics."
Modelling their time crystal on Google's quantum technology allowed the team to look for signs of infinite repetition within just a few hundred kicks of a laser pulse. They could also run the simulation backwards and scale its size.

> The sole reliance on vaccination as a primary strategy to mitigate COVID-19 and its adverse consequences needs to be re-examined, especially considering the Delta (B.1.617.2) variant and the likelihood of future variants. Other pharmacological and non-pharmacological interventions may need to be put in place alongside increasing vaccination rates. Such course correction, especially with regards to the policy narrative, becomes paramount with emerging scientific evidence on real world effectiveness of the vaccines.
...
> In summary, even as efforts should be made to encourage populations to get vaccinated it should be done so with humility and respect. Stigmatizing populations can do more harm than good. Importantly, other non-pharmacological #prevention efforts (e.g., the importance of basic public health hygiene with regards to maintaining safe distance or hand-washing, promoting better frequent and cheaper forms of testing) needs to be renewed in order to strike the balance of learning to live with COVID-19 in the same manner we continue to live a 100 years later with various seasonal alterations of the 1918 Influenza virus.

I don't think the author is an economist, but it's a fact that prices are rising by the day and some products are harder to get (or have disappeared).
