  1. Then a "scientist" is someone who does "science" professionally, or they inherited wealth so they could do science just for fun? Anyone know of an important science discovery, or won a Nobel Prize in sciences, in the past 50 years that did NOT come from a science professional or a person born into wealth, who didn't need to earn a living?
  2. The age of self delusion and alternative facts.
  3. Ok you got me there, but other than pro athletes and Olympic hopefuls, you really can't call someone who just exercises or plays at sports, an athlete.
  4. "When viewing space from Earth, the attenuation, interstellar dust, and stars in the plane of the Milky Way (the galactic plane) obstruct the view of around 20% of the extragalactic sky at visible wavelengths. As a result, optical galaxy catalogues are usually incomplete close to the galactic plane." Thanks for the link. This still doesn't make sense to me, because it is counter-intuitive. The galactic plane is a narrow band we see across only ONE side of the sky at night. That narrow band does not look like 20% of the sky. So the "attenuation" must be not only looking toward the center of the galaxy but all around us on the galactic plane, right? Not just the "zone of avoidance" which lurks behind the central band of the Milky Way, which conceals what the Milky Way is heading for, right?
  5. It seems to me that a "scientist" is someone that does "science" professionally, doing research, teaching, or other projects, not as merely a hobby. A musician is someone who does music professionally, not merely as a hobby. An athlete is someone who makes money from sports. Does anyone know of important science that came from non-professional scientists?
  6. Very interesting. It is hard for me to believe that the narrow band of the Milky Way, that we can see in the sky, hides 20% of visible light from the universe. Consider that narrow band compared to the entire sky, as viewed from the northern and southern hemispheres, surely we must see more of the observable universe than only 80% of it. Can you provide a source for your claim that the galaxy obscures 20% of visible light from the entire universe? Thank you, no hard feelings. 🙂
  7. "...the three elements, in general, that make up the crime of manslaughter. First, is a person “acting in a grossly negligent way when having a duty to act,” “Trump had a duty to act as President and violated that by knowingly failing to warn the public about the known threats of the virus.” https://www.thedailybeast.com/could-trump-be-charged-with-manslaughter-over-covid
  8. Wealthy people will need to invest in human survival to get the ball rolling. If humanity does not survive intact, with industrial power, then wealthy people do not survive either. Either that or there will be wars over water. Maybe there are other valuable minerals that can be extracted from sea water? Yes I doubt there is a shortage of salt. The basic idea is the water would not be sold, but used locally. Such an oasis can grow from humble origins. First you build a big water pipe from the ocean to a coastal desert, maybe within a few miles from the ocean. The water is delivered to an "initial" desalination plant that uses whatever power available to begin desalinating water for the local workers to drink and plant food to eat. Over time they construct concrete ponds with lensed-glass covers to magnify sunlight to vaporize water directly from sunshine, and condensation is collected. Then they build larger pipelines to deliver MORE sea water to MORE desalination ponds. Also they install solar panels and wind mills everywhere they can. The more power the better. Humanity better start creating fresh water before it is too late. Z: "Why do you want to do these things in the desert? Ocean water is available in lots of places that aren't so remote." Good question. Coastal deserts, that have cloud-free weather, would be chosen because you need: (1) square MILES of empty wasteland to construct desalination ponds, (2) you need lots of sunlight, and (3) you can't be too far from the ocean. If there are "lots of places that aren't so remote," then desalinate there also. People can even create fresh water in their back yards! All you need is a pit, throw in vegetation, cover it with clear plastic, and collect the condensation in a bucket in the middle. My next question for any climate science experts, would creating such oases, where before there was only a few desert cacti, cause a climate crisis? I don't think so. "A new paper paints a disturbing picture of a nearby future where people are fighting over access to water. These post-apocalyptic-sounding "water wars" could rise as a result of climate change and population growth and could become real soon enough if we don't take steps to prevent them. The study, which comes from the European Commission's Joint Research Centre (JRC), says that the effects of climate change will be combined with an ever-increasing number of people to trigger intense competition for increasingly scarce resources. This can lead to regional instability and social unrest." https://bigthink.com/politics-current-affairs/where-the-water-wars-will-be-fought
  9. There will need to be an initial investment to get it started, but over time the oasis-state could become self-sufficient. They could first sell fresh water and table salt, then later when farming is up and running, sell crops and other farm products, and sell energy from solar and wind. Sell glass made from desert sand for more desalination ponds. This would be a better investment than trying to colonizing Mars, the moon, or asteroids, which is just pie in the sky. Earth should be colonized and adapted to climate change BEFORE colonizing outer space.
  10. "Follow the water" is the astronomer's mantra for finding life elsewhere. So let's spread the fresh water around here on Earth! What do any climate science experts think of this idea? The idea is to "colonize Earth" by means of "oasis-states." An oasis-state is a plan to decentralize humans for survival on Earth in the face of disastrous climate change. It starts with giant water pipes that carry huge volumes of sea-water to previously uninhabited, inland deserts. The desert should not be too far from the ocean so you don't need to transport the water very far. The salt water is delivered to a new "oasis-state" that begins by desalinating sea water and then the fresh water is used for subsistence farming to support the workers. The idea is desalinate sea-water by sun power alone. The water is placed in concrete ponds, a few feet deep, that are a convenient size so the ponds can be covered with lensed glass (made from desert sand!) to rapidly heat the water until vaporization and the condensation flows out in pipes and hoses to be used for farming and other uses. When most of the water is vaporized the very salty residual water is pumped out so some can make salt, and the excess high salt water is dumped back in the ocean. These oasis-states can grow in size until there are thousands of concrete ponds desalinating water. Eventually there is much more fresh water than is needed for subsistence, the excess fresh water can be used to grow trees to suck co2 out of the air. These oasis-states can use solar and wind power.
  11. The weather here is Socal was unusually cool this summer as it was last summer. However this summer the unusually cool summer changed abruptly in September. The weather was cool then we got extreme high temperatures. We had about a dozen days over 110F and many more over 100F, with 116F as late as a week ago. That is what made wild fires in the west US much worse. The last several years the fires in California have been getting worse. ☹️
  12. It says "one doctor told CNN that the president could be guilty of negligent homicide."
  13. What else do you call a gross act of negligence that results in the deaths of others? Even up to 200,000 deaths? "Bob, I always wanted to downplay it. I still want to downplay it." Later Trump claimed to have "up-played it in action" and "downplayed" it in speech. He put a ban from China, but it was porous and the virus got to the US anyhow, also it arrived in the US from Europe. So what always mattered was Trump's choice of action AFTER the virus was already here. That is where he "choked." His constant downplaying caused people to not wear masks nor practice any social distancing. "During the town hall, Mr. Trump also repeated his claim that the virus will simply "disappear." The president claimed the population will develop a "herd mentality," seemingly referencing the concept of herd immunity." "And you'll develop, you'll develop herd — like a herd mentality. It's going to be — it's going to be herd developed and that's going to happen, that will all happen," the president said [ herd immunity in the US would require the deaths of 2 to 6 million Americans] "Mr. Trump has repeatedly given optimistic assessments of the pandemic's trajectory, including predicting in February, when there were only 15 confirmed cases in the U.S., that the number of cases in the country would go down to zero "within a couple of days." https://www.cbsnews.com/news/trump-town-hall-coronavirus-played-up-bob-woodword/ "The distinction between recklessness and criminal negligence lies in the presence or absence of foresight as to the prohibited consequences. Recklessness is usually described as a "malfeasance" where the defendant knowingly exposes another to the risk of injury. The fault lies in being willing to run the risk. But criminal negligence is a "misfeasance" or "nonfeasance" (see omission), where the fault lies in the failure to foresee and so allow otherwise avoidable dangers to manifest. In some cases this failure can rise to the level of willful blindness, where the individual intentionally avoids adverting to the reality of a situation." https://en.wikipedia.org/wiki/Criminal_negligence
  14. After thinking about this subject, and going down a Qanon rabbit hole, I think Qanon is the power of suggestion used on suggestible people. You will see a blurry photo that could come from anywhere, maybe a scene from "Saw" perhaps. Then a narrator explains what the blurry image is and tell a story that follows the script about Satanic, vampire, cannibal "elites" torturing children to stay young. A suggestible person may bite the bait. Perhaps some of the Qanon material could be of Russian origin, since that would be consistent with their objectives, to help Trump. The letter I posted at the start of this discussion looks like a clever person worked out a plausible fiction in a form letter to anyone interested, to rope them in. It looks as stupid as hell to me.
  15. Thanks for the info. Suppose someone sneezes or coughs and droplets of various sizes are ejected. These droplets float in the air, the heaviest ones drop to the ground. All the other droplets evaporate in minutes. That means the droplets all shrink in size until they completely evaporate and the virus is left dry and light as smoke. Then, as you said, sunlight kills the dry virus in minutes. That is why outdoor infections are low?
