Physics of Complex Fluids
The shearing of fluids—meaning the sliding of fluid layers over each other under shear forces—is an important concept in nature and in rheology, the science that studies the flow behavior of matter, including liquids and soft solids.
Shear forces are lateral forces applied parallel to a material, inducing deformation or slippage between its layers.
Fluid shear experiments allow the characterization of important rheological properties such as viscosity (resistance to deformation or flow) and thixotropy (decrease in viscosity under the influence of shear), which are important in applications ranging from industrial processes to medicine.

Studies on the shear behavior of viscoelastic fluids created by introducing polymers into Newtonian fluids have already been conducted in recent years. READ MORE...

Changing America
.jpg)
It is easy, at my age, to live in the past especially since the past is so much better than the present. However, if I had gotten cancer in the past, I would be dead by now because of the research that has been conducted on cancer research.
When I think of the past and what really impresses me about the past is not the cost of living or the quality of life but:
- we had a respect for American laws
- we had a respect for law enforcement
- we had a respect and trust in our legislatures
- democrats and republicans were willing to compromise
- we had a strong military presence
- we were leader of the world and respected by our enemies
- we had an outstanding educational system
- we had a strong set of values and morals
- we had a strong work ethic
- we believed a little bit of profit was necessary
- males were males and females were females
All of that has been lost... and that way of life is never coming back to America... a new generation of Americans have been born, that believe that type of life was based upon WHITE SUPREMACY and that minorities would never be given a chance... a new generation was born that believes in government handouts, social welfare, and socialism instead of capitalism.
While I am not a believer in their way of thinking, I do believe they have a right to take the country into the direction they believe is appropriate. And who knows... they may be right... maybe the time is right for a STAR TREK type of UTOPIA.
America's enemies have based their HATRED on the old America that manipulated countries by force if necessary and by money when appropriate, trying to transform their culture into an American culture since it was perceived that American culture was the best in the world.
WE WERE WRONG... But not many people are willing to admit that. However, I doubt our enemies will believe this younger generation and it is they who will start manipulating us.
Our colleges and universities teach student HOW BAD AMERICA IS RIGHT NOW... and, how out leaders need to be replaced and it is perceived that our enemies DO KNOW WHAT IS BEST FOR US.
An example of this is the PRO-PALESTINIAN & ANTI ISRAEL movement that is moving through this country like a hurricane and tornado combined. American Females want to be governed by SHARIA LAW, not fully understanding what they really means.
BUT... like everything else... CHANGE is necessary for growth... and America needs to grow into something that is different from that which it is currently.
An "Intelligent" Liquid
Harvard researchers have created a versatile programmable metafluid that can change its properties, including viscosity and optical transparency, in response to pressure. This new class of fluid has potential applications in robotics, optical devices, and energy dissipation, showcasing a significant breakthrough in metamaterial technology. (Artist’s concept).

Scientists have developed a metafluid with programmable response.
Scientists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a programmable metafluid with tunable springiness, optical properties, viscosity and even the ability to transition between a Newtonian and non-Newtonian fluid.
The first-of-its-kind metafluid uses a suspension of small, elastomer spheres — between 50 to 500 microns — that buckle under pressure, radically changing the characteristics of the fluid. The metafluid could be used in everything from hydraulic actuators to program robots, to intelligent shock absorbers that can dissipate energy depending on the intensity of the impact, to optical devices that can transition from clear to opaque.
The research is published in Nature. READ MORE...

Rare boson particle ‘triplets’
An extremely rare event in the world of particles has taken place during a Chinese-led study at the Large Hadron Collider (LHC) near Geneva, Switzerland.
And the event has scored yet another victory for the Standard Model – our current best theory to describe how the basic building blocks of the universe interact.
Sifting through experimental data collected between 2016 and 2018, researchers from Peking University and their colleagues from around the world spotted the simultaneous appearance of three force-carrying particles, known as bosons, which had never been seen together before. READ MORE...

The Right to Defend
.jpg)
If you are an American or if you in this country legally, then the umbrella of the First Amendment (Freedom of Speech), should apply to you.
In other words, if you want to organize a group of people for the sole purpose of yelling out to everyone:
DEATH TO AMERICA
Then you should have the right to do so. However, my question is: Why are you even here, participating in the freedoms and resources that exist here in America.
If you manage to kill all Americans, our freedoms DIE WITH US...
More importantly, you have not yet seen the anger of an AMERICAN once he or she feels like their family is being threatened, especially since we also have the Second Amendment (Freem to bear arms).
Let me suggest that you watch the movie RAMBO because something like that has a good possibility of happening.
EVERYONE... EVERY COUNTRY... has a right to defend themselves from aggression. It does not matter if you country is in the EU, or in Africa or South America, or is part of Asia, or is Russia or China - if another country acts in an aggressive manner towards you, then you have a righ to RETALIATE.
Case in point... Hamas attacked Israel, so Israel can retaliate. Hezbollah attacks Israel - Israel can retaliate. OR... If Israel attacks Syria and that pissed IRAN off - then Iran can retaliate as well... providing that Iran understands that Israel will respond in kind.
When Iran sent missiles and drones to Israel, the United States, the United Kingdom, Jordan, and France helped to defend Israel.
CONSEQUENTLY: DEATH TO AMERICA
It is very surprising that President Biden authorized the US military to become involved since Biden is a bit of a pussy when it comes to acting TOUGH.
What Iran and its proxies DON'T WANT is a war with America. If that were to happen, then Russia would support Iran and quite possibly China as well as other middle eastern countries.
BUT, the United Kingdom, the European Union, Japan, Australia, and other countries would support Israel and the USA.
What we would have is WWIII and only a fool would want a global war to become nuclear.
With that said, whatever you believe or don't believe, all countries have a right to defend themselves and retaliate if applicable. To think otherwise, is naive ignorance.
Synthetic Antiferromagnets
Researchers have discovered merons in synthetic antiferromagnets, advancing the field of spintronics toward more efficient, compact, and sustainable computing.
For the first time, teams from Germany and Japan have successfully identified collective topological spin formations known as merons within layered synthetic antiferromagnets.
Our everyday electronic devices, such as living room lights, washing machines, and televisions, operate thanks to electrical currents. Similarly, the functioning of computers is based on the manipulation of information by small charge carriers known as electrons. Spintronics, on the other hand, introduces a unique approach to this process.
Instead of the charge of electrons, the spintronic approach is to exploit their magnetic moment, in other words, their spin, to store and process information – aiming to make the computers of the future more compact, fast, and sustainable.

New Era in Health & Space
Researchers are exploring the world’s most powerful laser, which is now functional in a research center in Romania. The equipment holds the potential to bring about significant advancements in various fields, including space exploration and health.
The French technology company Thales uses ideas that have won Nobel prizes to run the laser at the European Union’s Extreme Light Infrastructure (ELI) center, located close to Bucharest, the capital of Romania.
The equipment at ELI produces the shortest and strongest laser pulses the world has ever seen by amplifying, compressing, and extending an extremely brief laser pulse over time. This has helped researchers overcome a crucial limitation with lasers: boosting power while keeping the intensity safe.
The technology has already been used in corrective eye surgery, but it has also made it possible for researchers to keep increasing the power of lasers. READ MORE...
