Yes, there ought to be a rule that you can leave those discussions, and just take part in the ones that interest you.

I may think that much of what Gabriel says is hogwash, but he has something of a point about that- and the pages he cited are evidence. Essentially, bearing a grudge is stressful.

Yes, you are confused. If I have a computer that does 1 trillion calculations per sec. and put it somewhere where time runs 1/2 as fast as where I am, then, for me that the computer only performs at 500 billion calculations per sec. I will have doubled my wait time, not halved it.

That's an interesting interpretation of taking 100,000 years of historical data and extrapolating 100 years into the future. (And , of course, by "interesting" I mean wrong)

It's impossible to tell. The Pool's pH is 8 so it is slightly alkaline. But we can't know if that is because it contains a small amount of a strong alkali, or a larger amount of a weak alkali. The best way to get some sort of answer is to take a sample of the pool water- say 1 litre and add small known volumes of the acid and measure the Ph change with each addition until you get to the pH you want. (It may be easier to measure the volume of a diluted acid.) Then you can scale up the amount of acid you need for the volume of the whole pool. I'd start by only adding half that much to the pool- to see what happens. You can add the rest if it turns out not to be enough. But it's very hard to remove it if you overdo it. Having said that, it's quite possible that adding the acid will have practically no effect on the pH. The cement in many pools will dissolve slightly and make the water alkaline. Adding acid will just make more cement dissolve.

When I can rub a few more brain cells together I'll take a look at the above. Discrete mathematics could possibly cover this. You see 'jumps' between numbers rather than what we're used to. https://en.wikipedia.org/wiki/Discrete_mathematics

No, I am sure that a number such as \(\sqrt{2}\) is an irrational number which is not a rational number. Come to think of it, I am even convinced that no irrational number is at all a rational number, purely by definition of those concepts. What prompts you to ask such a question? Also you are interfering with an existing thread, seemingly trying to support some kind of private agenda. If you insist on not answering the questions that are asked to you, the moderators may ban you.

Nice catch +1. In the context of the thread it is not relevant though, because we are dealing with just positive distances.

So all the proofs are just wrong, but you are not going to tell us where they go wrong?

Absolute numbers (as almost always) don't matter as much as quantity per area unit, and quantity per human (consumer of plant) (significant majority of pesticides will be flushed and plant cleaned, but not to absolute zero *). Quote from https://en.wikipedia.org/wiki/Pesticide "The US used some 1 kg (2.2 pounds) per hectare of arable land compared with: 4.7 kg in China, 1.3 kg in the UK, 0.1 kg in Cameroon, 5.9 kg in Japan and 2.5 kg in Italy. Insecticide use in the US has declined by more than half since 1980 (.6%/yr), mostly due to the near phase-out of organophosphates. In corn fields, the decline was even steeper, due to the switchover to transgenic Bt corn.[30]" i.e. GMO plants replaced normal plants, GMO were modified to be immune for attacking it microbes etc. thus pesticides are no longer needed (but seeds must be bought year-by-year, because they are made to be infertile). *) so yet another variable is how efficient is plant cleaning up procedure..

Add to this that as the glass is lowered hot air is displacing the cooler air in the glass.

Hello to all, Imagine two large holes A and B connect to a crack that leads to the center of the earth at the same point in the center. the center of the earth is it a temporal anomaly? What will happen if I drop dead in A or B? humans who travel in a place without mass towards the center of the earth are they the UFOs?

No, I just share my imagination with present and future humans.

I am a simple point who thinks I am the end point. A multiple point (thought) and at the same time alone. I can be in a complex (spirit) or simple (reality) plan. When I see my multiple points away from me. I remind them that we are one point. Every point away from me does the same thing as me. And every point close to me dreams with me. All points are reminiscent of the points. And there are certain points that follow imaginary paths. To remind you at the end point that he is not alone. It is thanks to that that the universe moves. and who are you?

The counterexample is the integers. That is not a well ordering but each element has a unique successor. IMO this thread has veered off course in the sense that discussing the definition of a well-order, or the mysterious properties of the rationals inside the reals, doesn't really help us understand the Cantor set. But clearly everyone else is happy so I'll stay out of it.

What does this have to do with anything? Is the opinion of one famous scientist evidence of the non-existence of God or gods? Why is his opinion worth more than anyone else's? I couldn't find anything in this article that verifies by experiment that man evolved from a hominid as a result of a process of mutations and natural selection. If I missed it, can you point out where, please?

Well, of course it is - every trait is the result of evolution! ... at least, to anyone who believes in evolution, it is. Why do girls like pink? Evolution. Why do males like sport so much? Evolution. Why are some people smarter/dumber than others? Evolution. Why do people fall in love? Evolution. Why do humans play music? Evolution. Why are there different races? Evolution. Why ... (fill in the blank) ... ? Evolution.

One can observe a tadpole evolving into a frog in a matter of a few weeks and you doubt macroevolution?!

! Moderator Note This is not the topic of the thread.

Your link there claims that the Higgs Field is not universal, and I don't believe that is true. Do you guys even use peer-reviewed references? I don't see how this all comes out to being proof when it is not peer-reviewed. Then most papers on the subject that are peer-reviewed don't talk about any details, and they only try to avoid talking about anything in a manner that could be seen as wrong to anyone by using big words with no apparent real world logical connections. Then it doesn't seem like any information about who is actually right or wrong could actually be proven by a reliable peer-reviewed reference. Then our only hope would be a moderator that actually read about Hawking Radiation in a pop science book that often includes an introduction about these random particle pairs, so the reader will know what they are talking about. In other words, we are all doomed.

A chimp made it into space before any human did, so chimps appear be evolving very fast. They could overtake humans as the dominant species on earth soon
