  1. Fresh vegatables and fruit do not have a shelf life of 2-4 weeks. You want me to eat chicken nuggets and canned beans? Uber's are exploitative. You want me to substitute a claimed immorality for a real immorality? Well no, if I actually were a peasant I would grow all my own vegetables and drive to town with a horse and cart. (And the local kids would run behind with a sack to collect the horse crap for the vegetable plot.)

  2. I find this to be true, and I find that both parties are responsible. Some people of science tend to forget how long it took them to get to where they are now. Understanding a concept or readily being able to discern science from pseudoscience is a skill that is developed over many years and with a lot of effort. It is easy to get frustrated with someone who seems oblivious to a concept that to a scientist is so obvious. It is often difficult to determine if someone is closing their ears to science or if they are just not experienced enough yet to process the information they are being given. I find that lay people often respond out of emotion instead of reason, and therefore find people of science to be arrogant. People generally do not like being told that they are wrong, sometimes spectacularly, and that they are often wrong because they were duped. That is tough on the ego. It is easier on the ego to get angry at the person correcting you, than to acknowledge that you were a fool.

  4. Good point. That's called the curse of knowledge. It doesn't happen only to scientists, though. There's also the curse of expertise.

  5. While I think there is a moral argument to made, the loss of life is perhaps not even a good indicator. Obviously we as a society accept loss of life to a certain degree. For example mild flu season roughly kill a similar number of people, and bad ones close to double of that. Still we do not make flu vaccinations mandatory, for example. I think a broader argument could be made for the overall impact of private vehicles (such as environmental impact) and balance them with need. One issue that the US has is that in most areas public transportation is really bad and the cities are built around car ownership. So to address the issue it requires a broader discussion on how to revamp cities and how to properly implement public transportation with reduced environmental impact. As a sidenote, the highest fatalities (and again, I do not think that this is really that important) are found a) among men in each age group (difference range from 57-75% of all fatalities per age group) and while the group of over 65 year old males are overrepresented, it is even worse for age groups 16-25. Using that logic we basically should only let women between 31 and 60 drive cars.

  7. Where did Pascal got the time to write such things down? According to most other philosophers, philosophy only exists in cultures where people have spare time. E.g. the Greeks had slaves, which gave their masters time to reflect on nature, society and themselves. People who have no time could be: full in the struggle of life: all their time is used to get food, shelter, and stay safe for any danger totally unaware that their world could be different as it is, i.e. accept the culture or society in which they live as a 'naturally given' and conform to to it without reflecting (My disclaimer could be extended from science to more or less all of life ("There is no such thing as philosophy-free science; there is only science whose philosophical baggage is taken on board without examination.")). Ideologically shaped societal dogmas are seen as 'natural', or 'obviously the best principles to live by'.

  8. Humans find patterns everywhere, even when there’s no legitimate pattern there. Seeing a face on the moon or a connection between eating bananas and smelly socks. You’re right to question whether your observations are valid. They’re probably not. You’re probably missing deeper and more important patterns, like the number of times an officer stopped and frisked them, or how many times fine people like you forgot to notice the good in them. Humans are also a bit random. You could notice the exact same pattern 10 times in 10 different people and get 10 different results. Just try always to find the humanity in others. Sometimes you’ll be let down, but rather often you’ll be pleasantly surprised. We kinda see what we’re looking for, so try looking for the good.

  9. [math]\alpha[/math] is a variable that ranges over the class of ordinal numbers. It doesn't have a formula. It's a variable that ranges over all the ordinals. It's used to index the sets [math]V_\alpha[/math]. Good. A more precise notation is [math]\displaystyle V = \bigcup_{\alpha \in Ord} V_\alpha[/math] where [math]Ord[/math] is the class of ordinal numbers. By the way I found the definition plus a detailed discussion of relativization in the Kunen link I gave earlier, starting on page 112. The bad news is that it's not self-contained. He refers to concepts discussed earlier in the previous 111 pages. And it's tough going. But at least it's a detailed definition.

  10. I think it is wrong to narrowly focus on the Trump administration. It is merely the result of at least decades of anti-science sentiments. One of the main topics used to be creationism which got a strong push into the open in the 2000s (incidentally one of the reasons why I joined this forum). The movement started well before that, though and was an alliance of industrial interests, conservative leadership and media. In essence it was a broader effort to undermine the very concept of scientific validity and thereby allowing politicians to act without the constraints of reality. Key efforts were obviously put on areas with monetary interest, such as climate change denial and over time it morphed into a weird form of conservative identity. Originally a bit fringy, over time it it became the mainstream we see today. This is not exclusive to the US, even in other Western countries, such as Canada, and Australia similar political efforts were made to silence scientists involved in climate change research. However, the cultural identification with denial seems to be an US export.

  11. How is using 1.25 hrs any different than saying 1 and a quarter hrs? or 1 1/4 hrs. The fact that the number is followed by "hrs" indicates that the numerical value is applies to the one unit, hours, while with 1:15 the ":" denotes a marker between units, or 1 hr, 15 min. I'm sorry if this confuses you, but when working with such problems it is easier to the work the math out in decimal hrs and then convert back to Hr and min afterwards if you need to. If the clock left you moving at 0.8c to a point 1 light hr away ( as measured by you), while both it and your clock both read 12:00, then it will take, by your determination, 1 hr 15 min to reach that point. You, however, will not see him arrive when your clock reads 1:15, as It will take an another hr for the light from his arrival to reach you, so you will see the image of his arrival 2 hr and 15 min after he left, when your clock reads 2:15. In other words, you will "see" his entire trip as being stretched out over 2 hrs 15 min. As you watched him recede from you, you will see him via relativistic Doppler shift. This does not only effects the measured frequency of the light you get from him, but also the rate at which you would "see" his clock tick. The Relativistic Doppler shift rate for 0.8c is 1/3. Since you see this happening for the entire 2 hr and 15 min, you will see that clock ticking off only 1/3 of that, or 45 min. Thus when you see the clock arrives at that point 1 light hr away, you will see it as reading 12:45.

  13. I was more talking about the coverage of the article. However, they discounted the possibility of SO2 because in order to observe the results they got, it would need to be a bit hotter (about double) than what is measured in the upper clouds. Surely the simpler explanation is that they detected SO2 that was a bit hot, as opposed to phosphine?

  15. I think you have to distinguish between deep-water/blue-water navies, and coastal ones (aka brown-water and green-water). A navy not designed to go far from the coast has no need of a carrier. And in that context, one must exclude land-locked countries from the count. I would expect that e.g. Uganda might have ships on Lake Victoria, but they would have no need of an aircraft carrier. Some land-locked countries would have just river boats. And many countries would have no navy at all.

  16. The Trump Administration seems to be getting quite explicit lately about something that's been in the air for quite a while. The man himself and some of his officials seem to be taking the anti-scientific discourse up a notch. Very worrying news coming from the US these days. I thought I'd never see the day: https://edition.cnn.com/2020/09/14/opinions/another-day-another-trump-outrage-on-climate-and-science-oreskes/index.html?fbclid=IwAR38oXn2xJLdp5rjnPZHeAsQtNSkkptKuZy_C3Sd3LJ5c2Usyv08TAzySQ8 https://www.nytimes.com/2020/09/14/us/politics/trump-biden-climate-change-fires.html?action=click&module=Spotlight&pgtype=Homepage&fbclid=IwAR38oXn2xJLdp5rjnPZHeAsQtNSkkptKuZy_C3Sd3LJ5c2Usyv08TAzySQ8 https://www.nytimes.com/2020/09/14/us/politics/caputo-virus.html What are your thoughts?

  17. Which is no doubt why the EU wishes to break International Law and steal our fish ?? I have yet to see any evidence that Boris' Bill breaks any Law national or international. Reporting on this issue is soley by comments from former leave campaigners who would no doubt like to hand the UK over on a plate.

  18. Sorry, but I think you do not understand the idea of this similarity. I'm going to grow up, maybe that's how the idea is understood: "different masses have the same gravitational acceleration is similar to different masses have the same electrical charge" Excuse me, but is super joke That's out of our discussion That's what I said in "Basic Ideas", there are similarities and differences. It just needs to be read carefully. I have already highlighted the idea, but I repeat it: "different masses have the same gravitational acceleration is similar to different masses have the same electrical charge" I answered why I did this " I just wanted to show that "different masses have the same gravitational acceleration is similar to different masses have the same electrical charge, to justify the description of the electric field, in the same way as the gravitational field, namely, to give it a form which will be described by space-time geometry. Therefore it does not matter how many bodies are. Please see the first paragraph of "Background of the study"."

  19. If you believe that everyday people should be allowed to operate motor vehicles then you are enabling immoral behavior. There were 36,560 motor vehicle deaths in the United States in 2018. There are far safer methods of transportation; including subways, buses, trains, planes, and bicycles. Those methods do not involve allowing common peasants to operate a machine weighing thousands of pounds that can reach speeds of over 100 mph. Older drivers, particularly those aged 75+, have higher crash death rates than middle-aged drivers (aged 35-54). If you are in favor of allowing common folk to operate motor vehicles then I have to ask, are you OK with letting your grandma die in a motor vehicle accident?
