`Unlike any other clock, this quantum watch does not utilize a counter and is fully quantum mechanical in its nature. The quantum watch has the potential to become an invaluable tool in pump-probe spectroscopy due to its simplicity, assurance of accuracy, and ability to provide an absolute timestamp, i.e., there is no need to find time zero.`

This is just absolutely brilliant.

I struggled with this a few decades ago, and had very heavy books that cost more than a weeks worth of food to learn from.

There's a lot to complain about in these modern times, but the level of free information available to those that care to look for it is not one of them.

Count your blessings and learn something awesome every day!

Playful Martian Dust Devils

The Martian atmosphere lacks the density to support tornado storm systems, but vortices are nevertheless a frequent occurrence. As sun-warmed gases rise, neighboring air rushes in, bringing with it any twisted shred of vorticity it carries. Just as an ice skater pulling her arms in spins faster, the gases spin up, forming a dust devil.

In this recent footage from the Perseverance Rover, four dust devils move across the landscape. In the foreground, a tiny one meets up with a big 64-meter dust devil, getting swallowed up in the process. It’s hard to see the details of their crossing, but you can see other vortices meeting and reconnecting here.

How come we’ve never observed a black hole decaying? Black holes, according to Stephen Hawking, should emit radiation from outside their event horizons, ultimately decaying away completely. So why haven't we ever seen it happening? bigthink.com/starts-with-... #space #astro #physics

How come we've never observed ...

Big ThinkHow come we've never observed a black hole decaying?According to Stephen Hawking, spontaneously emitted radiation should cause all black holes to decay. But we've never seen it: not even once.

@tomcapuder @cbontenbal Interesting. I think science definitely has a chance of making up something useful but we need a huge leap of faith to think it arrives at the truth.

Science keeps discarding things that were thought to be real like electric, heat fluids, luminiferous ether etc. We can make an inductive argument that it'll continue - the world as described by science will keep changing and therefore it is not real.

Multiple (sometimes incompatible and infinite) theories and interpretations exist which give the exact same phenomenon. The one accepted by science is based on luck - the first to make novel predictions.

We are stepping into the realm of the unobservable in advanced physics like string theory. Should we discard these pieces or update the definition and methods of science?

Success of scientific investigation is based on luck too. For example, billions of years in the future the light from other galaxies will be undetectable. But human records from today will say they observed many galaxies. Which one should the future humans believe?

So I don't think it's just "mental masturbation" to open our minds to other (potential) sources of knowledge. That's how we progress and enjoy life. 😄
