What Kind of Weapons Are Used On North Sentinel Island?
There is an island controlled by India that is extremely dangerous to go to because the Stone Age residents will try to kill anyone who approaches. As a result, India forbids travel to the island.
These islanders have been living there in isolation for 30,000 years.

This galaxy map is hiding a secret about dark energy
https://www.youtube.com/shorts/EoVQrsmnKC8
The number of galaxies in the observable universe is estimated to be between 100 billion and 2 trillion. This estimate is based on deep field observations and extrapolations across the sky. Some estimates place the number closer to 200 billion, while others suggest that the real number could be much higher, possibly in the trillions.

Did We Get the Double Slit Experiment All Wrong?
The double-slit experiment is a cornerstone of quantum physics. If our understanding of it were to change, it could upend the entire foundation of physics.
https://www.youtube.com/watch?v=DpMcC-E5l5c
This video doesn't explain the topic very clearly—it doesn't shed much light on it. 🙂 So, it feels more like an argument over semantics.
Einstein believed that quantum physics describes systems probabilistically because of hidden variables that we are unable to perceive. Personally, I think it's quite plausible that events occur on such an infinitesimal scale that they're simply beyond our ability to detect. In this case, we have to rely on theory instead of experimentation.
Water Purification and Removing PFAS from Water
I like drinking bottled water, which reportedly may not be much different from tap water—unless it's labeled as purified. To save money and avoid the hassle of buying bottled water, I was planning to get a water purification pitcher.
I spent a lot of time yesterday comparing different brands. I first came across this website:
https://www.goodhousekeeping.com/home-products/g39110423/best-water-filter-pitchers/
It recommends the Brita pitcher, primarily due to its low cost per gallon. Brita filters produce about 120 gallons of filtered water, making them very inexpensive to use.
However, after doing more research, I found that a couple of other brands are significantly better at filtering water, especially when removing PFAS. According to the video I referenced in my previous email below, PFAS are widespread in water supplies and can accumulate in the body over time, potentially posing health risks.
I saw a video comparing the Zerowater pitcher with Brita and Amazon-branded pitchers, and the Zerowater model performed far better, producing nearly pure water.
I initially planned to order the 10-cup version of the Zerowater pitcher from Walmart, but I found the 12-cup version at a lower price, so I ordered that one instead:
https://www.amazon.com/dp/B01JA5H7GK
How much does it cost to use?
-
Distilled water costs around $1.33 per gallon.
-
Member's Mark purified bottled water from Sam's Club costs about $0.81 per gallon.
-
The Zerowater pitcher is more expensive to use than other filter pitchers. Each $15 filter produces only about 15 gallons, roughly $1 per gallon.
You can reduce the cost somewhat by buying filters in bulk, and some compatible generic filters are available for about half the price.
I also mentioned considering a reverse osmosis system for my home, which might be a better long-term solution.

Achieving Fusion…again! NIF surpass their own record for energy generated
https://www.youtube.com/shorts/JXk_GPIXZgg
I don't see this ever becoming a practical fusion. According to one YouTuber, the claim of getting more energy out doesn't include all the energy needed to do the experiment, by a ratio of like 10 to 1.
We might get practical fusion either around the year 2100 or sooner, by necessity, since we will be running out of fossil fuels. But I don't think that it is likely in my lifetime.
According to Google AI, there is enough Uranium to power nuclear (fission) power plants for centuries. So maybe we are looking at the wrong technology. Much of the research is funded by the government, so I can't help but think that there is a mentality where we feel like we have to be the first to achieve it before our enemies do.

Storm
I was working on my computer when an alarm went off on my phone, followed by a citywide tornado siren and multiple tornado warning alerts and texts.
The last two warnings, both from this month, were for tornadoes near the edges of the county, far from my location.
I did the only reasonable thing: I stepped outside to check out the weather. I wasn't the only one. Just to the west, some ominous black storm clouds were gathering. It slowly started to rain, so I took shelter inside. The Weather Bug app indicated a fast-moving storm system overhead.
Then, the power went out. The storm sounded intense, so I temporarily hid in a large closet. It passed after a few minutes.
The power company sent a text estimating the outage would last until 2:15 AM.
I wonder whether there was actually a tornado.
Two years ago, a tornado on the far west side of the county caused a massive burst of wind in Columbus, knocking down trees all over the city, including on a property across the street. That storm sounded worse; I genuinely thought my house was about to be hit by a tornado.

How I Think About Climate Change
0 seconds ago
Neil,
It is possible that climate alarmists are correct and that human CO₂ emissions will lead to disastrous climate change unless we take drastic action. However, I have about a hundred reasons to believe they are not. We will find out in time because we are currently running the experiment. While some changes are occurring, they do not seem significant enough to warrant panic. I believe we have far more time to address this issue than alarmists suggest, as these changes are happening very slowly.
Looking at temperature data, it took approximately 140 years for the average atmospheric temperature to rise by just 1°C—starting from 1880, which was an exceptionally cold decade.
One major reason for resistance to drastic climate policies is that human civilization depends on cheap, reliable energy to thrive. The proposed solutions are often expensive, unreliable, and require draconian government controls. I do not want the government to control the entire energy sector unless there is an overwhelmingly strong existential reason to do so.
I have followed this issue for 37 years and have seen many dire predictions fail to materialize. Around 35 years ago, some claimed that we would face catastrophe within 25 years. Yet, our supposed doom always seems to be 25 years away—much like nuclear fusion. 🙂
As I mentioned earlier, the rate of change is slow, but another key factor is climate sensitivity to CO₂ doubling. Just 15 years ago, some climate scientists estimated climate sensitivity to be between 6 and 12°C. However, these predictions have gradually been revised downward. Around 2010, experts warned that we were on track for a 3°C increase by 2100 and that this would be dangerous, though a 2°C rise would be manageable. Less than a decade later, I saw similar claims, but the numbers had shifted: now a 2°C increase was the catastrophe, and 1.5°C was the new "manageable" threshold. The goalposts keep moving.
We have nearly doubled atmospheric CO₂ since pre-industrial levels—though not quite yet. However, we have not observed a 6–12°C increase. After analyzing temperature and CO₂ data from 1880, I did some calculations and estimated a climate sensitivity of around 2°C.
A 2015 graph comparing climate model predictions with actual temperature changes showed that nearly all models ran too hot. Only the Russian model was close to reality.
We now live in a political climate where truth is often defined by narrative rather than data. It is a post-truth society. There have been numerous reports of scientists struggling to secure funding or publication unless they align with the official narrative.
The IPCC is not an unbiased organization. They have refused to hire anyone who does not already subscribe to the belief in catastrophic man-made warming. This is not how science should be conducted—starting with a conclusion and working backward. Given that the IPCC is funded by governments, it should remain neutral and let data guide its conclusions. Instead, it behaves more like a political entity. The IPCC has also attempted to prevent skeptical papers from being published and has hired individuals affiliated with environmental lobbying groups—an obvious conflict of interest.
Some scientists have resigned from the IPCC, citing excessive bias. One former member stated that the real goal of the organization was to dismantle free-market capitalism.
Antonio Guterres, the socialist from Portugal who has led the UN since 2017, routinely makes exaggerated claims about climate change—such as his statement that oceans are "starting to boil."
Unfortunately, I do not trust the political system or academia to provide an honest assessment. I wish I could, but too many individuals and institutions appear to be pushing their agendas.
Best wishes,
John Coffey

It seems like the wrong approach. LLMs excel at language but are not well-suited for other tasks. The top chess programs, for example, are exponentially stronger than the best human players. A general-purpose AI would likely need to be a collection of specialized tools, each designed for a specific task. By developing enough of these tools, you could create a highly intelligent system.

Michael Mann Lawsuit Against Mark Steyn
Michael Mann is a climate scientist and a prominent figure in climate activism. He created the controversial "Hockey Stick" graph, which has been widely criticized for its methodology and accuracy.
Journalist and public speaker Mark Steyn referred to Mann as "a fraud." Mann, who has a history of suing critics, filed a lawsuit against Steyn. After a decade of litigation, Mann won a million-dollar judgment. However, an appeals court has largely overturned the ruling for misrepresentation by Mann and his lawyer.

Most common words in English
According to The Reading Teacher's Book of Lists, the first 25 words in the OEC make up about one-third of all printed material in English, and the first 100 words make up about half of all written English.[3] According to a study cited by Robert McCrum in The Story of English, all of the first hundred of the most common words in English are of Old English origin,[4] except for "people", ultimately from Latin "populus", and "because", in part from Latin "causa".

Re: CO2 removal and farming
If I had a choice to spend money and resources to take CO2 out of the air, or not, I would prefer to leave the CO2 in the air. It is a valuable resource. It is plant food. It is part of the food chain. Nature has ways of taking CO2 out of the atmosphere.
The CO2 level has been declining for a hundred million years, reaching dangerously low levels before we got involved.
There is a much bigger problem to worry about. We have been in the Pleistocene ice age for the last 2.6 million years. We should be in the cool-down portion of the Malankovich Cycles, which will lead to the next period of mass glaciation. It is thousands of years away, but it is a bigger issue than short-term warming that will last just a century or so.
I like a joke I heard: How far are we from Nuclear Fusion? About 93 million miles. Maybe we are looking for it in the wrong place, and just need better ways to collect solar energy.

elo score AI meaning
https://www.google.com/search?q=elo+score+AI+meaning&rlz=1C1ONGR_enUS1066US1066&oq=elo+score+AI+meaning&gs_lcrp=EgZjaHJvbWUyBggAEEUYOTIHCAEQIRigATIHCAIQIRigATIHCAMQIRigATIHCAQQIRigAdIBCDgzNjdqMGo3qAIAsAIA&sourceid=chrome&ie=UTF-8
An "Elo score" in the context of AI refers to a numerical rating used to measure the relative performance of an artificial intelligence model, typically based on a system borrowed from chess where models are compared head-to-head, with the winner gaining points and the loser losing points, allowing for a dynamic ranking based on their performance against other models; essentially, a higher Elo score indicates a better performing AI model compared to others in the same benchmark.
Key points about Elo scores in AI:
- The Elo rating system was originally developed by Arpad Elo to rank chess players, but has been adapted to evaluate AI models due to its ability to compare performance through pairwise comparisons.
- Head-to-head competition: Two AI models are pitted against each other on the same task, and a human evaluator or automated system judges which model produced the better output.
- Rating adjustment: Based on the outcome, the winning model gains Elo points, while the losing model loses points.
- Relative ranking: This system creates a relative ranking, meaning a model's Elo score indicates how well it performs compared to other models in the benchmark.
- Head-to-head competition: Two AI models are pitted against each other on the same task, and a human evaluator or automated system judges which model produced the better output.
- Elo scores are commonly used to compare the performance of large language models (LLMs) where different models can be evaluated against each other on tasks like text generation, question answering, or translation.

The guy fortified his garden but started putting out vegetables for the groundhogs so that he could record them for his YouTube channel.
A long time ago my father advised to never feed wild animals. You make them dependent. Animals know how to find food. However, I'm more worried about rabies, which is a deadly disease and especially common among raccoons. I've saw a video of a kind old lady feeding a bunch of raccoons. This can be dangerous.

Well, part of the reason why we have a shortage at air traffic control is because we were telling our air traffic controllers not to hire people because of the color of their skin."

The Top 10 Inconvenient Facts About Climate Change
This supports the things I have been saying.
The biggest threat to life is the next period of mass glaciation. It could take thousands of years, but we should already be in the cooling-down cycle. Even if we have a hundred years of warming, we have bigger environmental problems long term.
The Earth is halfway between its maximum tilt and its minimal tilt. We are 11,000 years away from the minimal tilt. All of human civilization arose during the last 11,000-year warm period.
The maximum tilt melts the glaciers because the summers are warmer. However, as the glaciers advance, a positive feedback cycle happens because the glaciers reflect more sunlight into space, rapidly cooling the planet.
It is possible that our effect on the climate could create a new normal. However, I don't see how we counter 90,000 years of cold before the next interglacial warm period.

Virus outbreak in China sparks pandemic concerns: What to know about HMPV
Videos have appeared on social media showing overwhelmed hospitals in China, sparking concerns of a potential pandemic.
The Chinese Foreign Ministry has attributed the spike to a regular seasonal surge, saying in a statement on Friday, "Respiratory infections tend to peak during the winter season … the diseases appear to be less severe and spread on a smaller scale compared to the previous year."
The CDC has said it is monitoring the virus through its National Respiratory and Enteric Virus Surveillance System (NREVSS).
"CDC is aware of reported increases in HMPV in China and is in regular contact with international partners and monitoring reports of increased disease," a CDC spokesperson said in a statement sent to Fox News Digital.
"These reports are not currently a cause for concern in the U.S., though some transmission of HMPV can be expected throughout the year, especially during the winter respiratory virus season."

Genetic Experts Reveal Shocking Neanderthal Secrets!
https://www.youtube.com/watch?v=3_VybJT_LFk&t=902s
There is reportedly some debate about whether Neanderthals were a separate species. Google search results say that they were. However, Neanderthals were close enough to us that I like the idea that they were a sub-species.
It is common for people of European ancestry to have a little bit of Neanderthal DNA. Someone I know did a genetic test that showed a higher-than-average percentage of Neanderthal DNA.
Genetic diversity is a good thing regardless of the species. It can help a group survive environmental changes. Under harsh conditions, some individuals die off and some survive. (Mother Nature is a bitch. 🙂)
