If you go clockwise from the top the thread goes over a thread, then under, over, under, over and under to get back to its starting point. Once you agree with that, I think the string can't be twisted to become an simple loop.
There is an interesting feat of DNA more or less counter to the example given: how a chromosome manages to unfold into a string with length of the order of centimeters during cell division without getting completely entangled.
Having some experience in IT development I'd think that the best feedback we get is from people who're smart, demanding, and difficult to get along with. One of the end users was generally so rude I suspect him of having Tourette's, but when he reported a fault, it was a fault. One can try to keep their bad attitude under control but not by ignoring what they're saying.
Safety! Now there's a new thought. He'll be hunting for some motorcycle helmets soon. A weak helicopter has an advantage over a real ground effect plane that it's better at avoiding obstacles (a 21 foot bush) but once the surface gets rough things start to eh, get rough. A ground effect vehicle above the jungle would go well for a few miles and then suddenly you drop through the foliage.
That depends very much where you drill I suppose. A rough estimate would be that if the crust is twice as thick, temperature will rise half as fast. I seem to recall that oil wells are only found far away from fault lines (it would be nice to know for sure).
That question is one of the easier ones, but if you drop the word "only" it becomes harder. There's a concept called decoherence. The early interpretation of the story where Schrodinger's cat exists in a superposition of a live and dead state is no longer acceptable. The interaction with the rest of the universe, and a bit of background radiation is already enough, lead very quickly(and you can calculate how quickly) to a state of universe+dead cat or universe+live cat. The weird mixed quantum states cancel out, effectively reducing the system to one of classical probabilities. So you can only experience one universe. The cat will either be live or dead, no in betweens.
The conservative interpretation is that quantum mechanics is still a probabilistic theory, not deterministic. There is one world, not many. There is not even a collapse of the wave function. The cat will be either live or dead, 50% each and you can't predict which one. But a lot of people have been attracted towards deterministic interpretations, and enter the many worlds interpretation. Now the wave function becomes the reality and the indeterminacy is shifted towards which path we follow in the branching tree of realities.
Most people think they are getting a good deal from that tradeoff. Then some start piling on more stuff, adding a "consciousness field" to make the choices at the branches. That's hoping they can solve one problem with another problem. Could be nice.
I don't think we're getting a good deal here. Obviously.
Arnica as herb medicin or as homeopathic medicin? It's not always obvious to see because the same company can make both. There are many instances where herb medicin works. People who use herb medicin tend to believe that it is better to use the complex "natural" mixture of substances as it occurs in a plant rather than extract one single component and make a pill of it, or make the component artificially.
White willow has long been known for its ability to kill pain, although it was very bad for the stomach. The active component was identified and then modified to make it less aggressive. Then it was made industrially. That became aspirin. It's possible to keep using willow bark but aspirin is less harmful.
Homeopathy conflicts with all of chemistry. Homeopathy claims you can keep diluting the active substance and the resulting liquid will become more and more powerful long after the last molecule of the active substance is gone. With dilution steps of 1/100, the last molecule of the original product is gone after 15 steps, or a factor 10e30. Homeopathic products are sold that use dilution factor 10e1000
My apologies for not replying earlier. I was away.
Your understanding of the relations between the theories and experiments needs some work. You can make a theory that has photons with mass 0 by definition, but photons are also experimental things. If a photon turns out to have mass it ruins the theory, but you're not suddenly going to call it by another name. Physics is not axiomatic mathematics.
Nobody expects photons to have a mass. If photons had a mass it would be a disaster for some theories but not for others.
- a correction to the theory electromagnetism would have been necessary. The constant C would no longer be identical to the speed of light. The correction would be easy to do, and it would be in accordance with relativity. For most practical purposes the old uncorrected E.M. would remain usable and there is no need to distinguish between C and lightspeed.
- The theory of Q.E.D. would be in an awful mess.
- Special and general relativity wouldn't change, apart from a rephrasing here and there to distinguish the constant C from the actual speed of light. Relativity did come from electromagnetism. The Lorentz transformation was based on electromagnetism and then used for relativity. You can construct the whole of electromagnetism from relativity and coulomb's law. But relativity and the Lorentz transformation do not depend on the experimental validity of electromagnetism.
The most recent solid experimental evidence that I know of says that photon mass is smaller than 1 E-17 eV. That's data of about 10 year ago.
The article is about another type of deviation for the speed of light and the conclusions may be different.
By itself variable speed of photons does not violate relativity. Suppose one day experiments would have shown that photons had a mass, like neutrinos. Then photons would not travel exactly the limit speed C. Relativity relies on this limit speed, not on the actual speed of photons. Electromagnetism does use C as speed of light. But then again, who expects such level of precision from a classical theory.
If Diebold seems incompetent, possibly malicious, with its election systems, why would you, the bank manager, trust them to build your ATM machines? Because Diebold did not break the golden rule that says who can fuck with and who you can't.
Pretty much every kid that watched Shrek 2 knew that Puss'n'Boots was giving himself a blowjob when the princess walked in and thought he was Shrek.
every kid who knows cats knows what this cat was doing. He was cleaning himself in the usual odd places. This is what cats do. That is funny and that is why it's in there. The idea that the cat was doing anything else at that time never occurred to me, but of course I was never exposed to Fritz the Cat when I was 8.

It requires effort from both sides to avoid the wrong impression.
The one I've got experience with (yearly) sounds like people with jackhammers working outside.
I absolutely agree that the argument of compressed music is completely beside the point. Record players do outperform CD players though.

But the helicopter will win from the ladder in the 100 mile dash across the savanna. Similar to a ground effect plane I would say. It could have uses.
- on
- off
- reset
- dump to make the helicopter light enough to hopefully clear that bush ahead.
this world needs it. or the cheapo version, d-face.
The first rule of keeping a secret is you only tell it to people who can keep a secret.
Interesting hypothesis, dyslexia as the origin of religion.

The inane comparison with how long a powerstation has to run to produce that much energy didn't do those astronomers any good either.

There are a lot of women who believe they don't exist if nobody is looking at them. Make that people.
because nobody was waiting for the result? Any doubt concerning the theory will focus on other areas.
And I can remain completely unmodded for no reason whatsoever.

And she walked out, not in. Neh!
Next you'll end up soliciting intelligence-related replies.
