  1. No It's important to have a pastime that you like doing. It doesn't have to be a job. 21st century economics is finally catching up with what Malthus said over 200 years ago. You can't have continuous growth if you have finite resources. That's going to rewrite the rulebook for economics to such an extent that I'm not sure that"economic system" will be recognisable.
  2. You need medical help, rather than a web page. Consult a doctor.
  3. I really don't understand this thread. Imagine I build a robot and I send it to do my job for me. I still get paid- because my work still gets done. But I am now free to do stuff like surfing the web or writing bad poetry or whatever. I can take time to cook better food, and I can spend more time walking in the hills near where I live. What's the downside? Now imagine that everyone does the same thing- all the work is done by robots and all of us are free to pursue our hobbies. Since everyone is in the same position, there's no need for anyone to rock the boat by saying that we shouldn't get paid. However, since nobody is actually doing anything important, there's no reason why anyone should be paid more (or less) than anyone else. And, since the machines are doing all the work, and they don't need paying, there's no reason why I need money to pay for goods and services. Sounds good to me.
  4. "How would an immune system 'allergic' to plain water would 'know' if someone just drunk plain water?" Very good question. The answer is that it could't. That's how we know that nobody is (or can be) allergic to water. Obviously, that leads to a different question; "What are these people suffering from?". Has anyone positively ruled out a psychological origin?
  5. I'd have gone with "assistant for the blind" As written above, it's ambiguous.It could be interpreted in the same way as the "blind watchmaker".
  6. I was wondering if you could get the same result by calculating the voltage needed to accelerate an electron ( or proton) to the escape velocity. Then use the capacitance of the earth (modeled as a conducting isolated sphere) to calculate the charge. However, I'm tired so I'm off to bed.
  7. "Who said the Universe had a beginning?" Olber.
  8. If the police wanted to know the answer they could repeat the experiment with the same barrel + fuels and using a small pig in place of the victim. If they don't try it, then it looks like they don't want to know.
  9. A wax candle burns at well over 1000C and vaseline is pretty similar to wax. It seems likely that you could get a hot enough fire. I have no idea how bad it would smell- not least because we don't know about the "design" of the burner. But a big enough fire would certainly destroy a body and it would just smell like a fire.
  10. A proper crematorium will destroy a body in 1 to 3 hours. I don't see any reason to believe that it would be impossible to build an "amateur" one and do the job in 18 hrs. I can't say I have any practical experience...
  11. I don't know. That's why I think it's clever
  12. There's the problem. "live your life as if God does exist". We don't actually know what (if anything) God wants. So, do I go to church on Friday, Saturday or Sunday? (and a thousand other similar questions.) You can't actually meet the requirement except by luck, and that makes it a very poor bet. Yes, of course I deny it, because I'm not an idiot and I like a lie-in on Sundays. So I know that the column on the right is incorrect. It should say "miserably dull sermon spoils roughly 14% of your life" and " doing what you choose on Sundays." So, even the straw man is factually incorrect.
  13. That's interesting. Devitrification normally stops the glass being transparent. It must have taken some clever work to get the crystals to have the same refractive index as the glass matrix.
  14. The trouble with Pascal's wager is that it's only a 1 in 3000 shot that you follow the right religion. Statistically, your God has already condemned you by accident of birth. You might as well have a good time.
  15. Did you somehow think that was relevant?
  16. Given the extremely violent reaction of oleum with water it's probably better to add the oleum to ice. It may also be a better bet to let it absorb water from the air (until it gains the right mass), but the fumes would be a problem. Fundamentally, if you can't do basic chemistry like the calculation above, you shouldn't be working with oleum.
  17. It makes no sense to talk about adding oxides of carbon (which are gases or too unstable to exist in molten glass). That web page is wrong. You could add carbon- which is black.
  18. So, the God who you say is showing love is condemning be by not telling me. That's a shitty way for Him to behave, isn't it? Bother! Best move this post too.
  19. God is notably not saying anything. He never did. You are making up what you want to hear.
  20. Probably a mixture but I'd expect that it's largely manganese that is giving that colour.
  21. You do know where they got it from, don't you? Leviticus 20.10 New International Version (NIV) “‘If a man commits adultery with another man’s wife—with the wife of his neighbor—both the adulterer and the adulteress are to be put to death. https://xkcd.com/285/
  22. Not unless you are straight and married, according to Leviticus. That's a poor argument. Douglas Adams squashed it more eloquently than I ever will, so here's a quote. “This is rather as if you imagine a puddle waking up one morning and thinking, 'This is an interesting world I find myself in — an interesting hole I find myself in — fits me rather neatly, doesn't it? In fact it fits me staggeringly well, must have been made to have me in it!'
