THE AIR CONDITIONING CRISIS???

THE AIR CONDITIONING CRISIS???

This is a HOT summer! We need air conditioning!

Do you still air condition your home using an air conditioning system that cools using R22 refrigerant?

Don't know? Better check it quickly! (The label on your unit will likely specify R22 as the installed refrigerant.)

From our research, in the United States of America, R22 refrigerant is being phased out. This phase-out has been known for decades!!!

If the homebuilders KNEW about the phaseout, why did they install these units???

Pity homeowners who need R22 refrigerant installed (especially people on a low fixed income). It appears that R22 refrigerant is not generally available.

Solution: Replace your unit (IF YOU CAN AFFORD IT)!!! (It appears that retrofitting MIGHT be possible.)

The following are U.S. Environmental

Three Mile Island MUST BE TAUGHT!!!

The Dooms Days Experiences of March 1979


Climate change! Climate change!! Climate change!!! How dare we teach about the urgency of climate change without fully educating young Americans about the existential catastrophe that could have resulted from the 1979 Three Mile Island crisis?

It was March 1979. Americans were going about their daily routines. Suddenly, seemingly out of nowhere, we began to hear about a nuclear power plant located in the state of Pennsylvania. Most of us had no knowledge of the plant. "Three Mile Island" they called it. Something was going on at Three Mile Island. We came to understand that Three Mile Island was a nuclear power plant. As one news report after another emerged, we learned that some kind of accident had occurred at Three Mile Island. At first, the...

THINKING THREE HUNDRED YEARS AHEAD

A MESSAGE TO 24TH CENTURY ENGINEERS

Greetings! This message is to people who are engineers in the year 2321 A.D. This is a message from the past (actually from 300 years in the past). In the past, the year is 2021. My name is Clarence William Page. I write in order to make a contribution to your age, your society, your world. To many of you, the past is a long time ago. I lived during that “long time ago”. We thought we were “modern”. We thought we were “advanced”. We invented much of what you consider rudimentary and mediocre (if not “ancient”). We took pride in something we called the “Internet”. (You have probably discarded it by now.) I have a few suggestions for you. Why for you and not for my generation? My generation would just reject them out of hand and call me a kook. (“Kook” was a word we used to ...

National Institutes of Health’s TOPMed program publishes Data on over 53,000 diverse Genomes | site |



NIH says historic findings could boost precision medicine, reduce health disparities


(Information contained in National Institutes of Health [NIH] press release dated: February 10, 2021)

Researchers supported by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health, announced the publication of a groundbreaking study which analyzed more than 53,000 whole genomes, primarily from minority populations. The study, which appears in the Feb. 10 online issue of the journal Nature, examines one of the largest and most diverse data sets of high-quality whole genome sequencing—a person’s complete set of DNA. The genetic data could shed new light on how heart, lung, blood, and sleep disorders impact people with diverse racial and ethnic backgrounds, who often are underrepresented in genetic...

Bringing Atoms to a Standstill: NIST Miniaturizes Laser Cooling | site |




(Information contained in National Institute of Standards and Technology [NIST] press release dated: January 21, 2021)

It’s cool to be small. Scientists at the National Institute of Standards and Technology (NIST) have miniaturized the optical components required to cool atoms down to a few thousandths of a degree Celsius above absolute zero, the first step in employing them on microchips to drive a new generation of super-accurate atomic clocks, enable navigation without GPS, and simulate quantum systems. Cooling atoms is equivalent to slowing them down, which makes them a lot easier to study. At room temperature, atoms whiz through the air at nearly the speed of sound, some 343 meters per second. The rapid, randomly moving atoms have only fleeting interactions with other particles, and their motion can make it difficult to measure transitions between ato...

NIST says Nanocylinder Vibrations Help Quantify Polymer Curing for 3D Printing | site |


(Information contained in National Institute of Standards and Technology [NIST] press release dated: December 10, 2020)

In a step toward making more accurate and uniform 3D-printed parts such as personalized prosthetics and dental materials, researchers at the National Institute of Standards and Technology (NIST) have demonstrated a method of measuring the rate at which microscopic regions of a liquid raw material harden into a solid plastic when exposed to light.

NIST’s custom atomic force microscope (AFM) with a nanometer-scale, cylinder-shaped tip revealed that the complex process of curing resins, as they ...

National Institute of Standards and Technology says New JILA Tools ‘Turn On’ Quantum Gases of Ultracold Molecules | site |



(Information contained in National Institute of Standards and Technology [NIST] press release: December 9, 2020)


JILA researchers have developed tools to “turn on” quantum gases of ultracold molecules, gaining control of long-distance molecular interactions for potential applications such as encoding data for quantum computing and simulations.

The new scheme for nudging a molecular gas down to its lowest energy state, called quantum degeneracy, while suppressing chemical reactions that break up molecules finally makes it possible to explore exotic quantum states in which all the molecules interact with one another.

The research is described in a Nature paper published online Dec. 9. JILA is a joint institute of the National Institute of Standards and Technology (NIST) and the University...

Error-Prone Quantum Bits Could Correct Themselves, NIST Physicists Show | site |


Novel error-correction approach could address a long-standing issue with quantum computers.


(Information contained in National Institute of Standards and Technology [NIST] press release: December 8, 2020)

One of the chief obstacles facing quantum computer designers — correcting the errors that creep into a processor’s calculations — could be overcome with a new approach by physicists from the National Institute of Standards and Technology (NIST), the University of Maryland and the California Institute of Technology, who may have found a way to design quantum memory switches that would self-correct.
