  1. It’s amazing how quickly their position switched from “recommending that people wear masks when they’re out in public is tyranny!” instead to “the government can shoot dead anyone who is out on the street at night and they can do so for any reason.”

  2. I doubt there was intent to murder and likely the cop thought what he was doing would not kill the man - especially with bystanders recording. A bit of time honored unofficial "teach the scum a lesson", perhaps intended for the bystanders more than George Floyd, but gone wrong? Perhaps every attempt George made to struggle and shift to get a breath was taken as defiance - and so he was held down harder and longer? The rioting and destruction of property is counterproductive of course - and it won't matter that the vast majority of protest was/is peaceful. I don't know how Americans will r

  3. Perhaps because we are living through a post-apocalyptic movie, the forum seems to be attracting a larger that usual number of people with their own wacky ideas about how the world works. So I put this together, partly based on my own observations but also a few pinched from the Crackpot Index (http://math.ucr.edu/home/baez/crackpot.html).

  4. I've heard a libertarian translate JFKs words as "Ask not what those in power can do for you...ask what you can do...for those in power"

  5. As a metallurgist and chemist, and someone who has worked in the mining industry, I am going to call BS on that one: Regular soil never holds what is essentially an ore grade of 6.8%. That is well over 1000 times the ore grade of even the highest grade gold ores in the entire world, let alone PGM's. Basically that guy is full of crap. Based on the first claim there is not much hope that that claim would be any more credible than the first one.

  6. Would that be a bad thing? I do myself subscribe to the idea that those in power should be held to higher standards than those that are not, and that if you do something wrong or abuse your power, you should be punished more severely (the higher you are, the longer the fall. comes to mind).

  7. Here I think you're being persuaded by a subtle misconception. When entropy has reached a maximum, the system has undergone total thermalization and nothing statistical depends on time. Things keep changing, but only microscopically. All the physical parameters are fixed at their average value. Any changes will manifest themselves in second order effects or fluctuations. If temperature is high, the system will be very efficient at erasing these deviations from equilibrium very quickly. Some months ago, I developed a picture meant to illustrate these concepts, only for educational purposes, and

  8. @studiot said that when you will pass current through molten sodium chloride, there will be produced metallic sodium and chlorine gas.. But you did not say you will be passing current through it, but it is plausible thing which you maybe omitted in your OP.

  9. The diagram mentions gravity, that implies a third object: earth. Here's a list of third-law-force pairs I see in the diagram where a book is laying on a table standing on earth. First force -- Second force Downward force of gravity on the book exerted by Earth -- Upward force of gravity on Earth exerted by the book Downward force on the table exerted by the book -- Upward force on the book exerted by the table Downward force on the ground exerted by the table -- Upward force on the table exerted by the ground (one pair at each leg of the table) Downward force of

  10. @drumbo For the most part mainstream plan or policy for transition to zero emission is NOT based on enforced energy poverty; high emissions infrastructure is not being prematurely closed without alternatives in place. Better policy, that accounts for potential inequality, is the best result emerging from studies that show potential for inequality. Climate policy, for all the lies that are made about it by climate responsibility denying opponents, is not about reducing prosperity, it is about preserving it in the face of accumulating and economically damaging global warming. I no

  11. Yes I agree, Turing took one of the many steps along the development of IT, he did not invent the Von Neuman architecture (I wonder who did that ?) Although originally a theoretical mathematician, Turing was also practical as evidenced by rewriting the intensively theoretical Godel theorems into a practical (if gedanken) setting). But modern IT is about more than just about one thing. It draws together many disparate aspects of technical knowhow. But it is difficult to list the many who contributed to the drawing together of the many different threads without missing someone out, o

  12. What qPCR kit (or just enzyme) do you use? It depends on both the primers in question (how easily do they form primer-dimers) and the enzyme used, however I generally used 250 nM (for both the forward and reverse primers). Optimal primer concentration can only really be obtained by titration, but I have only done this (once) when initial results were dubious/contained primer-dimer peaks (increasing annealing temperature wasn't really viable/did not help either). When titrating, Thermofisher (Sybr Green) recommends checking the 100-500 nM primer range, however other researchers sometimes check

  13. I disagree that this is necessarily true - though i'm sure it is sometimes, maybe often, the case. Iff religious beliefs make an empirical statement that clash with the evidence then sure there will be dissonance. Then there will always be evidence gaps in which people can ferret certain beliefs which avoids this dissonance. But if religious beliefs make no such empirical claims then they can be entirely consistent with science. Another way of stating this is that religion (could) deal with the world as we experience it, science as the world is. Or that God does exist - as a human c

  14. The second link in OP (https://emilkirkegaard.dk/en/?p=7237) states that the 10% claim is "bullshit". It does not support the 10% claim and gives several reasons why the number may be incorrect. Talk page of wikipedia "List of nonreligious Nobel laureates" states "The main source of this article is not reliable": https://en.wikipedia.org/wiki/Talk:List_of_nonreligious_Nobel_laureates#The_main_source_of_this_article_is_not_reliable Good points, I'll add a local example. Wikipedia lists 32 swedish laureates. During the years of Nobel Prizes Sweden have made several changes*

  15. Religious beliefs are based on 'faith', which requires no evidence or facts. Science is based on evidence and facts, and some people are more adept than others at determining/discovering that evidence or building models that attempt to explain those observations. On the other hand, sometimes being truly exceptional ( as Nobel prize winners are ) requires a 'leap of faith'. does that maybe explain how the two correlate ? ( I don't know, I'm just making this stuff up as I go )

  16. First the non-vascular bryophytes (mosses, liverworts, hornworts) during the Ordovician period (which started around 490 million years ago) that evolved from green algae. Mosses lack true leaves, true roots and vascular tissue. It therefore can’t conduct sugar or water through the plant, only diffusion and osmosis. Then came the vascular seedless plants (ferns, horsetails, clubmosses) during the Devonian period (which started around 420 million years ago). A fern is vascular, but still contains spores, just like moss, and thus a swimming flagellated sperm cells. The oldest-known vascular
