Never-Before-Seen: UCLA Physicists Discover Mysterious Spiral Patterns on Solid Surfaces
Hundreds of regular patterns spontaneously emerge on a small germanium chip.
A curiosity about tiny dots on a germanium wafer with metal films led to the discovery of intricate spiral patterns etched by a chemical reaction. Further experiments revealed that these patterns emerge from chemical reactions interacting with mechanical forces through a deforming catalyst. This breakthrough marks the most significant advance in studying chemical pattern formation since the 1950s. Understanding these complex systems could shed light on natural processes like crack formation in materials and the effects of stress on biological growth.
University of California, Los Angeles doctoral student Yilin Wong noticed tiny dots appearing on one of her samples, which had been accidentally left out overnight. The layered sample consisted of a germanium wafer topped with evaporated metal films in contact with a drop of water. On a whim, she examined the dots under a microscope and couldn’t believe her eyes. Beautiful spiral patterns had been etched into the germanium surface by a chemical reaction.

Siblings and Families
How close are you to your brother (s) and sister (s)?
It is not that easy an answer for several reasons.
- do you have one brother and one sister?
- do you have just one brother or one sister?
- do you have two sisters?
- do you have two brothers?
- what is the age difference between your siblings?
- did you parents have a favorite (s)?
- was there any bullying going on?
- the various career paths that were taken.
Influences
The closer the years in between, typically the closer the siblings.
The influence of the parents influences the closeness as well.
The financial wealth of each sibling (s).
The career path of each sibling (s).
The mobility of each sibling (s).
Probably the most important issue that I have been able to discover that separates or brings siblings together is:
WHAT THEY HAVE IN COMMON
That may not seem like much of a big deal but it is because if two siblings have very little if anything in common, then there is absolutely no reason for them to get together outside of the parents. Once the parents are deceased, there is NO REASON for them to get together.
This HAVING SOMETHING IN COMMON holds true for parents and children as well.
If the parents are uneducated and the child or children are, then there is very little in common and no reason to get together, outside of respect for holidays. Grandchildren present a reason to get together but after they reach a certain age, the reasons start to diminish.
Most of American families for these reasons are no longer close. The family unit is breaking down.

A fitting monument to Trump?
Friends,
Imagine we are alive a decade from now. We’ve survived Trump, Vance, and Musk. We are trying to cope with the wreckage they’ve left us with — trying to put back together our government, our democracy, our Constitution.
What do you believe will be a fitting monument to the memory of Trump?
I raise this question because Trump’s Republican lapdogs in Congress aren’t waiting until after the Trump regime to come up with such a monument.
They’ve already filed a rush of bills seeking to honor Trump while he is still in office.
It’s a brown-nosing effort without precedent in congressional history — revealing the lengths Republican suck-ups are willing to go to curry favor with the nation’s would-be dictator.

Politics...
What is it?
What is it not?
The American people elect politicians to positions so that these elected officials can make decisions on our behalf.
Currently, we have two main political parties: the democrats and the republicans. The democrats represent our liberal views concerning how decisions should be made while the republicans represent our conservative views.
Consequently, whichever party wins a particular election, the other party will automatically be AGAINST just about everything that the winning party wants to do on behalf of the American people.
Politics takes place on the Federal level with the President and the Congress being elected by the general public with the Supreme Court and other judges being elected by the party that is currently in charge.
Then there is the State and Local level of politics which works in the same way with governors, state legislatures, mayors, city councils and judges.
Along each level of election, Americans are exposed to the influences of one party over another party in making decision for their citizens and residents.
This is AMERICAN POLITICS and immediately creates an ADVERSARIAL RELATIONSHIP between the citizens of our country. Over the years, this adversarial relationship has become more and more intense and has created a level of HATE between the two parties that has never been seen before.
Our political future is in question...
Quantum Breakthrough: Scientists Create Schrödinger-Cat State With Record-Long Lifetime
USTC researchers created a long-lived Schrödinger-cat state, boosting quantum metrology and precision measurements. Their findings open new possibilities for quantum computing and fundamental physics.
A research team led by Prof. Zhengtian Lu and Researcher Tian Xia from the University of Science and Technology of China (USTC) has successfully created a quantum state with a lifetime on the scale of minutes using optically trapped cold atoms. This breakthrough significantly improves the sensitivity of quantum metrology measurements. Their findings were published in Nature Photonics.
In quantum metrology, particle spin serves as a powerful tool for measuring magnetic fields, inertia, and various physical phenomena. It also has the potential to uncover new physics beyond the Standard Model. A high-spin Schrödinger-cat state, a superposition of two maximally opposed spin states, offers unique advantages for precision spin measurements.
