How Long Earth Can Stand The Pollution?
John Cuthber replied to Ian Zonja's topic in Climate Science
Close, bu no cigar. This post was the one I made when I got back from the pub. As for pointing out your glitch- better late than never. Incidentally, "sober" isn't usually a verb. "Sober up" is. So you should say " It's good to sober up prior to replying, don't you think?" But I think you are right about your 2nd PS. (and I think some might benefit from an "I'm stoned" warning too.) -

If I accidentally step on your toe should I apologise to some random stranger at a later date, or should I apologise to you? -
How Long Earth Can Stand The Pollution?
John Cuthber replied to Ian Zonja's topic in Climate Science
I can make the comparison quite easily. I go to the bank and explain that I want to put solar panels on my house to heat it (instead of using oil fired heating). I don't have the cash to pay for it, so I want a loan. And, as you say, the panels last about 25 years so I will take out a loan over that period. (In principle,I can then take out another loan for new panels when I need them. And the bank will be happy to tell me what the loan would cost- in terms of monthly repayments. I can then simply compare one set of monthly bills (oil + delivery etc) with the other (loan repayment etc.) (There are maintenance costs too but I can simply include them in my calculation) Now, it's not unreasonable for me to assume that the price of oil will rise- and it's possible that the interest rate will change. But, for now, I can compare the two options. Incidentally... "You can't predict price of oil" "It can, and will, go high," You just predicted it. -

And the shameful thing is that the church says we are forgiven- by someone's invisible friend- but that "feeling better" is only legitimate when the forgiveness is from the one actually wronged. Nasty bastards, aren't they? -
Because Canadians don't want Trump, or his sort of politician. The question isn't why not, but why? What would Canadians gain?

John Cuthber replied to boo's topic in Religion
Is this "confession" thing where you ask someone to tell you that their invisible friend says it's OK that you did bad things? I'm fairly sure that the acceptance must come before the confession. So, while acceptance maybe the first step, there is no requirement for confession to be any step. Its entirely possible to do without it. -
Why would it be? Are you assuming you can't get the right answer?
-
Why? In any event, you can check by titration. HBr does not conduct.

It is perfectly reasonable for science to favour a hypothesis which has (potentially) predictive utility and is testable.

Pesticide Residues Detect And Removal
John Cuthber replied to Barcelona's topic in Inorganic Chemistry
Acetic acid will mix with gasoline. Vinegar will not. Yes, provided that the materials are stronger bases than the acetate ion. Most pesticides don't meet that criterion. It's possible that this myth came into being when "Bordeaux mixture" - a mix of copper carbonate, sulphate etc was widely used. The rest of your post is pretty much irrelevant to the removal of pesticides. Mind you, the whole topic is based on a misconception. Why bother to remove them? -
Pesticide Residues Detect And Removal

And how did you come to the conclusion that such a process would work? Is it because vinegar is magical? -
How will we survive if machines are taking most jobs?
John Cuthber replied to Vexen's topic in Other Sciences
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. -
You need medical help, rather than a web page. Consult a doctor.

How will we survive if machines are taking most jobs?
John Cuthber replied to Vexen's topic in Other Sciences
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. -

What purpose does this blog serve? -
Why not? Water does the same thing.

"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?

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".

Why is the Earth electrically neutral?
John Cuthber replied to Bluemoon's topic in Astronomy and Cosmology
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. -
Who said the Universe had a beginning?

"Who said the Universe had a beginning?" Olber. -
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.

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.
-
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...

I don't know. That's why I think it's clever
