Biden's Disinformation Board


1984 by George Orwell 
Orwell’s novella is a warning for the human race

War is Peace. Freedom is Slavery. Ignorance is Strength.

1984 is a dystopian novella by George Orwell published in 1949, which follows the life of Winston Smith, a low ranking member of ‘the Party’, who is frustrated by the omnipresent eyes of the party, and its ominous ruler Big Brother.


‘Big Brother’ controls every aspect of people’s lives. It has invented the language ‘Newspeak’ in an attempt to completely eliminate political rebellion; created ‘Throughtcrimes’ to stop people even thinking of things considered rebellious. The party controls what people read, speak, say and do with the threat that if they disobey, they will be sent to the dreaded Room 101 as a looming punishment.

Orwell effectively explores the themes of mass media control, government surveillance, totalitarianism and how a dictator can manipulate and control history, thoughts, and lives in such a way that no one can escape it.

The protagonist, Winston Smith, begins a subtle rebellion against the party by keeping a diary of his secret thoughts, which is a deadly thoughtcrime. With his lover Julia, he begins a foreordained fight for freedom and justice, in a world where no one else appears to see, or dislike, the oppression the protagonist opposes.

Perhaps the most powerful, effective and frightening notion of 1984 is that the complete control of an entire nation under a totalitarian state is perfectly possible. If the world fell under the control of one or even multiple dictators, the future could easily become a twisted, cruel world where every movement, word and breath is scrutinised by an omnipotent, omnipresent power that no one can stop, or even oppose without the fear of death.

Orwell’s novella is a warning for the human race. It highlights the importance of resisting mass control and oppression.


Is this the kind of society in which you want to live?  A government that decides FOR YOU what is truth and/or what is not truth (DISINFORMATION)...

Right now, we have free will to decide what is truth and what is not truth and it is our choice to decide if we are right or wrong...  but now, the government wants to take away our free will and decide for us...

Is this something that we really want???

A crooked government could take a lie and make it TRUTH...

For instance.... a government could decide that slavery never happened and if someone says that slavery did happen in America is passing out DISINFORMATION...


Education's BIG Mistake



I have been involved with higher education about 30+ years on a 45 year career... and the main problem that I see is that my students don't know how to think...  they don't know how to drill down on a subject...  they don't have any presentation or communications skills and for the most part write at a 10th grade high school level...

However, if you tell them exactly how you want something done, they will copy your instructions exactly because they know in doing so they will get an "A".  Many of them no only have not retained anything but if you ask them what they retained in the class before this one, they will typically say "nothing" or "I cannot remember".

One day, educators are going to wake up and realize what they have done...

Backwards in Time


A wild new theory suggests there may be another "anti-universe," running backward in time prior to the Big Bang.  The idea assumes that the early universe was small, hot and dense — and so uniform that time looks symmetric going backward and forward.

If true, the new theory means that dark matter isn't so mysterious; it's just a new flavor of a ghostly particle called a neutrino that can only exist in this kind of universe. And the theory implies there would be no need for a period of "inflation" that rapidly expanded the size of the young cosmos soon after the Big Bang.

If true, then future experiments to hunt for gravitational waves, or to pin down the mass of neutrinos, could answer once and for all whether this mirror anti-universe exists.

Preserving symmetry
Physicists have identified a set of fundamental symmetries in nature. The three most important symmetries are: charge (if you flip the charges of all the particles involved in an interaction to their opposite charge, you'll get the same interaction); parity (if you look at the mirror image of an interaction, you get the same result); and time (if you run an interaction backward in time, it looks the same).

Physical interactions obey most of these symmetries most of the time, which means that there are sometimes violations. But physicists have never observed a violation of a combination of all three symmetries at the same time. If you take every single interaction observed in nature and flip the charges, take the mirror image, and run it backward in time, those interactions behave exactly the same.

This fundamental symmetry is given a name: CPT symmetry, for charge (C), parity (P) and time (T).

In a new paper recently accepted for publication in the journal Annals of Physics, scientists propose extending this combined symmetry. Usually this symmetry only applies to interactions — the forces and fields that make up the physics of the cosmos. But perhaps, if this is such an incredibly important symmetry, it applies to the whole entire universe itself. In other words, this idea extends this symmetry from applying to just the "actors" of the universe (forces and fields) to the "stage" itself, the entire physical object of the universe.

Creating dark matter
We live in an expanding universe. This universe is filled with lots of particles doing lots of interesting things, and the evolution of the universe moves forward in time. If we extend the concept of CPT symmetry to our entire cosmos, then our view of the universe can't be the entire picture.

Instead, there must be more. To preserve the CPT symmetry throughout the cosmos, there must be a mirror-image cosmos that balances out our own. This cosmos would have all opposite charges than we have, be flipped in the mirror, and run backward in time. Our universe is just one of a twin. Taken together, the two universes obey CPT symmetry.

The study researchers next asked what the consequences of such a universe would be.  They found many wonderful things.  READ MORE...

One Way Time Travel


Have you ever made a mistake that you wish you could undo? Correcting past mistakes is one of the reasons we find the concept of time travel so fascinating. As often portrayed in science fiction, with a time machine, nothing is permanent anymore – you can always go back and change it. But is time travel really possible in our universe, or is it just science fiction?

Our modern understanding of time and causality comes from general relativity. Theoretical physicist Albert Einstein's theory combines space and time into a single entity – "spacetime" – and provides a remarkably intricate explanation of how they both work, at a level unmatched by any other established theory.

This theory has existed for more than 100 years, and has been experimentally verified to extremely high precision, so physicists are fairly certain it provides an accurate description of the causal structure of our Universe.

For decades, physicists have been trying to use general relativity to figure out if time travel is possible. It turns out that you can write down equations that describe time travel and are fully compatible and consistent with relativity. But physics is not mathematics, and equations are meaningless if they do not correspond to anything in reality.  READ MORE...

The Space Plane


The X-37B looks like something our of a sci-fi movie. What is the plane’s actual mission? Was it designed to fight a space war against Russia or China? At first glance, you think you are looking at a miniature version of the space shuttle, but the X-37B is an unmanned and autonomous space plane with its own quirks and characteristics. 

The craft is also known as the Orbital Test Vehicle, and it has flown six missions since 2010. At only 29-feet long, the X-37B is just a fraction of the size of the space shuttle. It’s also boosted into space on a rocket, and it lands horizontally like an airplane. Let’s take a look at just why the United States needs such a curious spacecraft.

Most missions and their details are classified. Could it be used to take out enemy satellites? That question has been bandied about by space war analysts. But the U.S. military denies such offensive activities and claims the X-37B is for peaceful purposes as a technology and scientific testbed. 

For example, it could be trying out new tech for spy satellites and other types of orbiting vehicles. The X-37B could also be gathering data on vertical launch mechanisms for flight control and testing other space components.  READ MORE...

Einstein's First Wife

A photograph of Mileva Marić and her husband, Albert Einstein in 1912.




While Mileva Marić was married to Albert Einstein, many believe she greatly contributed to his world-changing discoveries — only to be denied credit later on.


In 1896, a young Albert Einstein walked into the Polytechnic Institute in Zurich. The 17-year-old student was beginning a four-year program in the school’s physics and mathematics department. Of the five scholars admitted to the department that year, only one of them — Mileva Marić — was a woman.


Soon, the two young physics students were inseparable. Mileva Marić and Albert Einstein conducted research and wrote papers together, and soon began falling in love. “I’m so lucky to have found you,” Einstein wrote to Marić in a letter, “a creature who is my equal, and who is as strong and independent as I am! I feel alone with everyone else except you.”

But Einstein’s family never approved of Mileva Marić. And when their relationship soured, Einstein turned against his wife, and may have robbed her of crucial credit for her work on “his” groundbreaking discoveries.


Who Was Mileva Marić?

Mileva Marić was born in Serbia in 1875. A bright student from her early years, she quickly moved to the top of hlber class. According to Scientific American, in 1892, Marić became the only woman allowed to attend physics lectures at her Zagreb high school after her father petitioned the Minister of Education for an exemption.

According to her classmates, Marić was a quiet but brilliant student. Later, she became just the fifth woman at the Polytechnic Institute to study physics.  READ MORE...

The X-59, NASA’s quiet supersonic experimental aircraft, has arrived back at Lockheed Martin’s Skunk Works facility in Palmdale, California, following several months of critical ground tests in Ft. Worth, Texas.

NASA’s X-59 Quiet SuperSonic Technology aircraft, or QueSST, is designed to fly faster than the speed of sound without producing a loud, disruptive sonic boom, which is typically heard on the ground below aircraft flying at such speeds. 

Instead, with the X-59, people on the ground will hear nothing more than a quiet sonic thump – if they hear anything at all. The X-59 will fly over communities around the United States to demonstrate this technology, but first, NASA needed to validate the X-plane’s acoustic signature, using a ground recording system.

Ground tests on the X-59 were done to ensure the aircraft’s ability to withstand the loads and stresses of supersonic flight – or flight at speeds faster than Mach 1. The vehicle’s fuel systems were also calibrated and tested at Lockheed Martin’s Ft. Worth facilities. 

With its return to California, the X-59 will undergo further ground tests as it approaches full completion of its development and continues to make progress on its way to first flight.  READ MORE...

Recycling Lithium Batteries


Electric vehicles, power tools, smartwatches—Lithium-ion batteries are everywhere now. However, the materials to make them are finite, and sourcing them has environmental, humanitarian, and economic implications. Recycling is key to addressing those, but a recent study shows most Lithium-ion batteries never get recycled.

Lithium and several other metals that make up these batteries are incredibly valuable. The cost of raw lithium is roughly seven times what you'd pay for the same weight in lead, but unlike lithium batteries, almost all lead-acid batteries get recycled. So there’s something beyond pure economics at play.

It turns out that there are good reasons why lithium battery recycling hasn’t happened yet. But some companies expect to change that, which is a good thing since recycling lithium batteries will be an essential part of the renewable energy transition.
Lead-acid lessons

How extreme is the disparity between lithium and lead batteries? In 2021, the average price of one metric ton of battery-grade lithium carbonate was $17,000 compared to $2,425 for lead North American markets, and raw materials now account for over half of battery cost, according to a 2021 report by the International Energy Agency (IEA).

The imbalance of recycling is counterintuitive in terms of fresh material supply as well. Global sources of lithium amount to 89 million tons, most of which originate in South America, according to a recent United States Geological Survey report. In contrast, the global lead supply at 2 billion tons was 22 times higher than lithium.

Despite the smaller supply of lithium, a study earlier this year in the Journal of the Indian Institute of Science found that less than 1 percent of Lithium-ion batteries get recycled in the US and EU compared to 99 percent of lead-acid batteries, which are most often used in gas vehicles and power grids. According to the study, recycling challenges range from the constantly evolving battery technology to costly shipping of dangerous materials to inadequate government regulation.  READ MORE....

Death Spiraling Moon

NASA’s Perseverance rover has captured the clearest ever footage of a solar eclipse over Mars, and the results are out of this world.

The rover snapped the ethereal video of Mars’ potato-shaped moon, Phobos, moving across the face of the sun on April 2. During the eclipse, Phobos projected its uneven shadow over the Martian surface — appearing almost as though it was the pupil of a gigantic eyeball rolling in its socket.

Perseverance recorded the footage midway through its journey to a river delta on Mars’ 28-mile-wide (45 kilometers) Jezero Crater, where it will search for evidence of life on the Red Planet. Training its state-of-the-art Mastcam-Z camera on the sky, the rover recorded the misshapen moon’s solar transit with the greatest zoom and at the highest framerate ever.

"I knew it was going to be good, but I didn't expect it to be this amazing," Rachel Howson, a mission operations specialist at Malin Space Science Systems and one of the Mastcam-Z team members who operates the camera, said in a statement.

Phobos, named after the Greek god of fear, is roughly 157 times smaller than Earth's moon and is one of Mars' two natural satellites, alongside the even smaller Deimos (whose name comes from the Greek god of dread).

Scientists believe that the brother moons were once roaming asteroids that were snared into Mars’ orbit by the planet’s gravitational field. The orbits of these captive asteroids are unstable, according to researchers, and scientists predict that in a few tens of millions of years' time Deimos will spin out into space while Phobos will slam into Mars’ surface.  READ MORE...
