If you have something whose position varies sinusoidally with time then the acceleration is a cosine curve and the derivative of that is a sine function so you are back to where you started. You can keep differentiating as often as you like- the functions are all well behaved. There's a similar situation with an object moving in a circle. The acceleration is always towards the centre of the circle and the rate of change of the acceleration is circular too. You can differentiate as much as you want.

Here's a hint Could you list the professions that have succeeded? The sad truth is that there's nothing very spectacular about "Hollywood". This inequality is very widespread. One might hope that our politicians, film stars and other "celebrities" would set a good example; instead they demonstrate the truth of the assertion that power corrupts.

Or that adding up even numbers gives an even number. 2+0 =2 It's laughable that you need anything complicated to prove it.

Would you like to list the professions where it doesn't exist? Here's an interesting example; albeit rather late in the day, Weinstein is being held to account and sacked. Trump was made president. What kind of message does that send to women who are considering reporting this sort of issue? In the interest of fairness, feel free to consider Bill Clinton instead of Donald Trump.

One reason why Aluminium is easy to recycle is that the process of melting it removes a lot of contaminants. The dregs of beer or cola in a drinks tin stop being a problem by the time it has reached 600 C or thereabouts. It is true that it's easy to pick out of a waste stream- the same is even more so for iron/steel; you just need a magnet. Glass was recycled well by simply making sure that the milkman picked up the empties when he dropped off the mil;k on the doorstep. (Or by having a small army of kids who valued the 6d they could get by returning a bottle to the shop.) It would be better to have compostable packing for food, but there are two mutually exclusive requirements. The packing needs to prevent /retard decomposition of the food in storage yet it needs to decompose when it's useful life is over. That might be possible, but it's not clear how to make it cheap. Perhaps everything should be packed in aluminium tins.

Spot the difference. OK, set up a test of memory and see if the results are linked to date of birth. Or even look at the dates of birth of famous athletes- presumably their physical energy is above the norm. I think you will find a small effect of season of the year, but not one for phase of the moon. Come back with data I might even help out with the analysis. Here's a start. Find the dates of birth of this lot; most of them will be on line somewhere https://en.wikipedia.org/wiki/List_of_multiple_Olympic_gold_medalists

In that case the cathode would be plated almost entreaty with copper because it's much easier to reduce to the metal than tin is. Plating with alloys is possible, but difficult.

Well, good for you. It is an important result, but it's not news. https://en.wikipedia.org/wiki/Uncertainty_principle#Examples

Yes, he's a primate but since he's not a monkey (he's one of the great apes), your suggestion doesn't work.

If you make up a set of questions of the sort that get used in IQ tests (or, indeed, pretty much any questions), and get enough people to answer them then you can see if there's a correlation of test score with date of birth. It doesn't need to be an "official" inteilligence test. You can, if you want, look at the data and see if you can normalise the scores to some sort of "IQ" like distribution- a mean of 100 and a SD of 15, but that's not the point. But, all you need are a bunch of "scores" and dates of birth. Members here might be prepared to help you out with that. Then you can do the analysis and, in all sensible probability, lay your idea peacefully to rest. A useful first question might be "have you had your IQ resumed professionally and, if so, what was the result?". Then you can check if your new test correlates with "real" IQ. If you want to test the hypothesis that "clever people are born at the full moon" then any sort of measure of "cleverness" would do. Even salary might work as a proxy- as long as you took age into account somehow. If the effect is as big as Chris first claimed, the effect should show up even with a fairly lousy measure of "cleverness".

It's difficult to imagine a container for fizzy drinks that's robust enough to be useful, yet is compostible. On the other hand, aluminium cans are very recyclable and I'm old enough to remember when glass bottles were returned to the shop (for the few pennies deposit [paid on them) and reused. There is no "one size fits all" solution to packaging.

Reality does not know, or care, what you would prefer.

Milk is just about the only thing whose "purpose" in life is to be eaten. You are saying we shouldn't eat it. Would you like to think that through? They sure did. http://www.health.com/celebrities/alkaline-diet-creator-jail-time

And I repeat that there is. Nobody understands it.

Some of the papers are interesting, this one, for example, https://www.ncbi.nlm.nih.gov/pubmed/23020073 but I think it would be a mistake to think it's a major breakthrough.

"A slightly different version of General Relativity" So, that's slightly different from the one that gives the right answers...

If you have had to say it more than once, it's clear that you should, indeed, clarify your post.

Sadly, lotteries are a tax on the poor.

Reminded me of this http://www.snopes.com/humor/jokes/hydrogenbeer.asp

Well, "with a twist" is an interesting choice of phrase. Do you know about this? https://en.wikipedia.org/wiki/Polarimeter

True, it has a "work of fracture" of about sod all. Steel light bulbs would be much less likely to shatter if dropped. (And they would be about as much use as a photochromic light bulb)

Oxygen, on its own, is not explosive. Hydrogen, on its own, is not explosive. Hydrogen peroxide, on its own, is explosive. Do I need to expand on that? If you decomposed H2O2 to form H2 and O2 then you would end up with "spare" O2 in terms of making rocket fuel. It would make more sense to decompose water, that way you would get H2 and O2 in the right proportions to make- you guessed it- water, when burned in a rocket Also the batteries you would need to produce the electrical power for splitting the H2O or H2O2 would be very heavy. H2O2 is used (sometimes) in rocketry because it's (all too) easy to get it to decompose to steam and oxygen. That reaction is very easy and gives out lots of heat. Getting the steam to decompose further to give hydrogen and oxygen is so difficult that they use the reverse reaction- the combustion of hydrogen to make steam to do things like... drive rockets.

Glass is actually very strong, especially in compression (most things are better in compression than tension). Bulbs are typically filled with a low pressure of some inert gas- often argon (because it is cheap). Krypton and xenon are also used.

That would be a start. Citing them (directly) would be good too. If you can show that the hydrogen actually stays in the "hydrogen infused water", rather than diffusing straight out. I will be interested.
