Fact-Checking this Viral Bottle Trick
https://www.youtube.com/watch?v=jbgvQNhFDTo
A couple of decades ago there was some research into using somnolescent bubbles to try to make nuclear fusion happen.
I always assumed that there was something to this, but apparently not.
Watch "The mathematics of weight loss | Ruben Meerman | TEDxQUT on YouTube
I was confusing this video with a similarly titled video that I saw years ago that claimed that the mathematics of weight loss was just calories out versus calories in. Although technically true, weight loss is more complicated, with certain foods like sugar being worse than others. Sugar actually stimulates appetite. In addition, our gut flora send signals to our brain to stimulate our appetite for specific foods. Those bacteria get hungry, and different bacteria prefer different types of nutrients. Eating healthy foods adjusts your gut bacteria to that diet.
This is where probiotics might be helpful.
In addition, I just read about "obesogens", which at first sounded like a joke to me, which are chemicals in the environment that promote obesity. https://www.ehn.org/chemicals-in-everyday-products-are-spurring-obesity-warns-a-new-review-2657191067.html
In terms of the chemistry of metabolism, this video is scientifically interesting. However, it isn't really news that we lose mass as we breathe out carbon dioxide.

Hands down the best scientific explanation of weight loss. The bottomline: eat less and move more.

Re: DNA, CO2, Studies, fuel cells and superconducting diodes
We have had the solution to carbon capture for a long time in the form of Iron Fertilization: https://en.wikipedia.org/wiki/Iron_fertilization
I still think that atmospheric CO2 is a valuable resource.

These 200,000-Year-Old Hand and Footprints Could Be the World's Earliest Cave Art
https://www.smithsonianmag.com/smart-news/these-200000-year-old-hand-and-footprints-could-be-the-worlds-oldest-cave-art-180978702/
Maybe a couple of kids found some soft or wet limestone and decided to leave their handprints.

Study reveals some brain changes, even in mild COVID-19 | CIDRAP
The study authors noted that the imaging differences between the two groups were modest, at about 2% of average baseline values. The typical annual loss of gray matter each year due to aging, the researchers said, is 0.2% to 0.3%.
Cognitive tests identified differences between COVID-19 survivors and controls, including a significant increase in the time taken to complete Trails A (numeric; 7.8%) and B (alphanumeric; 12.2%) of the Trail Making Test in COVID-19 participants. These results held true when excluding the 15 hospitalized patients (Trail A, 6.5%; Trail B, 12.5%).
"The infected participants also showed on average larger cognitive decline between the two timepoints," the study authors wrote. "Importantly, these imaging and cognitive longitudinal effects were still seen after excluding the 15 cases who had been hospitalised."
Not all COVID survivors have brain changes
In addition to the modest COVID-19 effect, the study authors noted that the statistics represent an average effect, meaning that not every COVID-19 survivor will experience brain changes.

Fwd: Carl Sagan Predicts Our Countries Future
FYI.
---------- Forwarded message ---------
From: John Coffey <john2001plus@gmail.com>
I had seen this. He has a point that if people don't understand science then they don't know the difference between real science and fake science.
However, most people have very little need or ability to understand science.
Back when they announced that they were going to try to find the "Higgs Boson" using the "Large Hadron Collider", the naturally curious person that I am asked the questions, "What the hell is a 'boson'?", and "What the hell is a 'hadron'?" I have since learned enough physics to understand these concepts. It has become a hobby of mine to study physics. As a result, I have the kind of knowledge that 99% of the population would find useless.
Carl Sagan's show was really good.
However, I don't fully trust him as a source. In his show, Cosmos, he said that free-market capitalism was dangerous. He later bragged about smoking marijuana.

Seems like COVID is now almost a non-issue
Because of my family situation, I still feel the need to be careful.

Solving The Problem Of Human Perception | Jordan Peterson Lecture at The University of Cambridge
https://www.youtube.com/watch?v=5HgSnS-z4JU
Jordan Peterson went through at least 18 months of suffering because of illness, so he often gets emotional in his lectures when previously he was cool as a cucumber.
He talks at such a high intellectual level that it takes effort to keep up. He covers many topics and jumps around so much that sometimes you wonder if you are listening to a crazy person. He does a halfway good job of tying it all together, but I feel like he could be more succinct.
He quickly gets to the point before moving on to related topics. Then he wraps it all together with a conclusion.
His claim is that we perceive the meaning or the utility of objects rather than just the objects. Since we are talking about automatic mental processes, it is hard to say in what order the brain processes information. Maybe we first recognize the object and then its function. Maybe function is so tied to our perception that we perceive it simultaneously. Since it is hard to know, does it really matter?

10 Years On Mars: Curiosity Finds Plastic Debris!

How ironic it would be if Curiosity were to find plastic on Mars not caused by humans. They say plastic can last forever. How about a billion years?
Best wishes,

Little Cobra Gets Sips Of Water From A Sprite Bottle During His Rescue
https://www.youtube.com/watch?v=db9MgEfHLgY
It is next to impossible for me to feel compassion for a creature that is poisonous enough to kill an elephant. It might make sense for a snake collector, but to release this monster back into the wild is to risk the lives of others.

Law of averages
I tend to assume that if something hasn't happened for a while that it is more likely. This is a gambler's fallacy.
If you roll dice a million times then the numbers that come up will resemble a bell curve with 7 being the most likely result, but past events don't predict future random events. The law of averages works because large samples hide short-term aberrations.
The exception might be when dealing with human choices that otherwise would be random. Some people might have tendencies to do or not do particular actions.
Re: 50 CAL VS TRAIN TRACK RAIL

I'm impressed. Railroad tracks are made from hot-rolled steel and are designed to be tough.

This type of weapon must have considerable power. I'm thinking of the third law of motion, where every action has an equal and opposite reaction. The weapon must be able to deal with recoil.
Best wishes,
