Interesting, I didn't know who the guy was so I had a look on wiki and found this "In December 2009, Johnson revealed that he had been battling Hepatitis C for over a decade, which resulted in slow speech and a tendency to regularly get "lost in thought in the middle of a discussion"." So at least he has a reason for losing the plot.

"Air flow is very strong. With smoother object there is smaller problem with air flow as you saw in my video. Why you are ignoring facts? " Nope it isn't, and nope, I'm not the one ignoring facts here. Let's do some actual maths. Ok in the test we had the back wheel is turning at 5 rotations per second, it's radius is .350m;and a test object 2 mm away from it. The object looked to be about 5cm in diameter. That's an area of about 2E-3 square metres. The most force the air could apply would be if it was travelling at the same speed as the wheel (about 11 m/s) and transfered all that momentum to the weight. So. imagine a "block" of air, travelling at 11 m/s and the same cross section as the weight. It runs into the weight and transfers all its momentum to it. How much is that? The density of air is about 1.2 kg/m^3 and the swept volume is 0.002 X 11 i.e 0.021 m^3 which will have a mass of about 0.025 Kg and , since it's travelling at 11 m/s it will impart about 0.3 kgm/s of momentum to the test weight each second which is a force of 0.3 kgm/s/s or 0.3 N (in practice it will be less than that) Since the maximum force that the air could exert is 0.3 newtons there's no way it is responsible for the fact that your proposed 15N is not observed. If there were a 15N force then a 0.3 N force from air currents wouldn't affect it. Now do you realise that your "theory" is dead?

That rather misses the point that (unlike practically anything else you can buy) a gun is designed to make killing people easy. Why make it easy for nutters to kill lots of people? As John points out, having more guns present doesn't make the situation better, even when they are in the hands of trained officers. The idea that a cinema crowd would have done better is laughable.

Well, we know that it wasn't due to air currents- they simply are not strong enough to overcome a 15 N force. So what "known reasons" caused it to fail?

The "theory" failed: it is dead. How long are you going to carry its corpse around asking people to look at it?

Anyone who wants to can Google nitrogen triiodide and find out how to make it. They are not very likely to come across this page. However it's possible that someone will be interested in ammonium fluoride melts and find this page. If it tells then to be careful about adding halogens to the mix then it's beneficial.

Do your trousers have turn ups?

The gelatine capsules certainly won't survive the acid etc. in the stomach. So, shortly after you swallow the capsules, the carotenoids will be exposed to those acids anyway. Carotenoids are fairly readily destroyed by light and air so I'd suggest only opening the capsules shortly before you swallow the contents.

It's not magnetic. It doesn't rust. It's a fairly good conductor and it's springy. You might want to change the name of this thread to something that's related to its contents.

Yes it is. You can't have a "theory of everything" that doesn't include maths because without maths you can't make measurable predictions. If you are now telling us that you don't have the maths then you are (rather belatedly) telling us that you don't have a theory. Is that the case? If it is then we can close the topic. We tried the experiment and it failed. If the force had been anything like 15 Newtons it would have easily overcome the forces due to air drag. It didn't.

"I heard that in its molten state, it makes a good solvent for halogens " I don't know whom you heard that from, but I think you should stop listening to them http://en.wikipedia.org/wiki/Nitrogen_trichloride http://en.wikipedia.org/wiki/Nitrogen_triiodide \Are quite likely products from the reaction.

"I've heard ruthenium is great for heat retention" I doubt that. http://en.wikipedia.org/wiki/Dulong%E2%80%93Petit_law

Can you (meaningfully) optically image something with a size that's roughly a twentieth of the wavelength of visible light? It will just look like a dot.

Illusio, Run and hide! For roughly a hundred years mankind has been looking for a way to breach that conservation of energy and , together with Klaynos' interpretation (well, one of them anyway) you have done it. You have (it seems) solved the energy crisis. All I need to power my home is a flywheel connected to a generator. If I put a couple of business cards under one side of the wheel they will shield it from gravity. So the other side will be heavier and will fall. Of course, as they fall they will come into the "shielded" area in turn so the net effect will be to turn the wheel continuously. I can collect all the power I need from that magic gravity wheel. But your problem is different. All the world's leaders depend on having an established "system" in place to control their minions. One examples of that is the government's ability to tax things like electricity. The usual conspiracy theory is that ideas like this are stamped out by the oil industry but the reality is that they never happen. The laws of thermodynamics see to that. Since your discovery that a couple of bits of cardboard can shield gravity, we no longer need to use the conventional sources of power like oil. We can produce our own. The political consequences are astounding. But I fear that you r discovery will cause great fear among those in power. In the end it will be the salvation of mankind but most politicians are too "short termist" to understand that. You need to hide. Long Live the Revolution! p.s. I'm kidding. You have not broken the laws of physics and you don't really need to hide.

I had the idea in mind that someone might (boringly) buy a steam engine. Making your own would be risky.

OK, so I think that you are not paying a lot of attention to what you do and therefore shouldn't be playing with thermite. Your response is to point out that you don't know what you wrote and didn't realise you should check. " I thought I italicized that myself,"

I wonder if any of these ideas will be more efficient than burn the wood, use it to run a steam engine and use that to run a generator. Somehow I doubt it.

Well, we did the test. The theory failed. The force on the test weight should have been rather more than 10 times its weight so the string should have been nearer horizontal than vertical. It wasn't. The theory doesn't agree with reality. That's not because reality is wrong.

Monetary Units’. None. In fact, there are three freely convertible currencies in the universe, but the Altairian Dollar has recently collapsed, the Flainian Pobble Bead is only exchangeable for other Flainian Pobble Beads, and the Triganic Pu doesn’t really count as money. It’s exchange rate of six Ningis to one Pu is simple, but since a Ningi is a triangular rubber coin six-thousand, eight-hundred miles long each side, no one has ever collected enough to own one Pu. Niginis are not negotiable currency because the Galactic Banks refuse to deal in fiddling small change. From this Basic premise it’s very simple to prove that the Galactic Banks are also the products of a deranged imagination. from http://www.clivebanks.co.uk/THHGTTG/THHGTTGradio5.htm

OK, back to the topic. I really think that trying to prepare calcium by a thermite type reaction is likely to be hazardous. I therefore do not think it should be done by someone who does not pay attention to what they are doing. So I don't think that it's a good idea for someone who not only gets utterly the wrong hydration number for Calcium sulphate, but can't spot his error even when it's quoted back at him with the mistake highlighted by italicisation. It's not an issue of formatting. It's an issue of watching what you are doing, and thinking it through clearly. I invite you to consider the reaction of a little trapped water with white hot Al or Ca and calculate the volume of gas (be it H2 or H2O) formed.

I agree that Obama's just not in the news as much as Bush was but I don't see that this is true "Compared to Bush II there simply isn't as much about Obama in the MSM outside the US. (Or at least not down under) This leaves one with the impression that he's rather lack lustre and colourless with no real convictions." It leaves me with the impression that he has screwed fewer things up. The media don't report "the president did something sensible today". BTW, take a bow for choosing to describe the guy as "colourless".

I suggest hanging the test mass from a string. That's a very sensitive test for any force acting on it because the string won't hang vertically. You should be able to get a plot of the angle from vertical vs the speed of the wheel. Ideally we would do this in a vacuum, but with 15N acting on a 0.1 Kg test mass the string should be very clearly out of vertical.

Which words on this page have had attention drawn to them by putting them in italics?

That's proof (of a sort) that it hasn't been round forever because all the unstable isotopes would have decayed. But it doesn't prove that it's cyclic. We may or may not get a "Big Crunch" but the isotopes don't tell us what will happen.

Yes. Quite a lot of things that are bitter are toxic, which is why we tend not to eat them. Sadly, people sometimes get stuck with eating things that are slightly toxic (especially if not properly prepared) because they don't have any alternative. http://en.wikipedia.org/wiki/Cycad#Uses http://en.wikipedia.org/wiki/Cassava#Food_use_processing_and_toxicity http://www.eattheweeds.com/tulips-famine-food-appetizer-assistant-2/
