Stop strawmanning. What I said was "Both will bioaccumulate to a similar extent ) because they have fairly similar chemistries." and "What we are talking about are two materials that are chemically fairly similar, tend to get mistaken for one another by biological systems and are both beta emitters." And you were kind enough to provide a reference that says " Radiocaesium follows potassium and tends to accumulate in plant tissues, " OK so your own reference says "Radiocaesium follows potassium". So, while I'm saying they are quite similar, your reference shows that they are quite similar. Saying that "potassium and cesium are not ecologically distinguished" is your invention, not mine. But don't get too tied up in that strawman to remember to look at answering this one. This seems to be a pretty clear claim " 2) Why are you assuming the concentration is even throughout the plume? " prove it. Show that I have made that assumption.

Angular momentum is transferred to and from the rest of the world. It doesn't notice much.

Still nonsense. I pointed out that the contamination in the worst of the big scary blob was, in fact less radioactive than ordinary sea water (and by a fairly large margin). That's not the same as saying it was all the same concentration, is it? So, once again... This seems to be a pretty clear claim " 2) Why are you assuming the concentration is even throughout the plume? " prove it. Show that I have made that assumption.

Ho Hum The plume I'm talking about is (obviously) the one in the picture I cited which was produced at a point in time. That picture isn't changing is it? So I'm not making an assumption that the plume is even. So your point was an attack on a position that nobody was taking. It was a strawman. This seems to be a pretty clear claim " 2) Why are you assuming the concentration is even throughout the plume? " prove it. Show that I have made that assumption. Incidentally,, s there anyone else out there who thinks that by saying that Everest is the highest mountain, I am assuming that the world is flat, or do you have to be Overtone to take that viewpoint?

biological product molecules vs synthetic molecules
John Cuthber replied to StudentJames's topic in Chemistry
"what should i be mainly looking for? " A better job. There is not a difference between the two. A molecule of water doesn't "know" if it is in a living thing or not. the idea that there was a difference was killed off a long time ago. http://en.wikipedia.org/wiki/W%C3%B6hler_synthesis There are lots of molecules that are very difficult to synthesise and it's easier to get them from biological sources- Morphine and digitalin for use in medicine are still obtained from plants because it's much easier (and cheaper) than synthesising them. In some cases it's possible to trace the origins of a molecule to a biological precursor. http://www.ncbi.nlm.nih.gov/pubmed/21107978 but in principle, it's always possible to make the chemical synthetically.- 1 reply

I have the same thing about being a notbutterflycollectorist. On the other hand, I can't argue against the idea that "not believing in god is often central to what makes them atheist. " It's true that not being theist is what makes me atheist; more or less by definition. I'm also not very concerned about the concept of God disappearing any time soon. After all, I can still look up the references for the luminiferous ether, phlogiston and so on. Just because we know something doesn't exist doesn't stop the concept existing. I just wonder if this is any more or less meaningful that Brokeal's point I believe in unicorns, I think there is no good or evil if we didn't know unicorns, it gives me hope, and a reason to live. unicorns will not disappear because we all know about the concept of unicorns, we all think about it

The burst was definitely not due to fusion- there's just not an adequate energy density to provoke that. It's quite a challenge to get what most people would recognise as an explosion without plasma. Anything much more energetic than a burst tyre is going to make plasma. What do you think the phrase "a plasma explosion" means?

Ultra- Super- and Sub-diagonal Matrices
John Cuthber replied to Sarkuzi's topic in Analysis and Calculus
This seems close, but it's not the matrix itself that's subdiagonal. http://en.wikipedia.org/wiki/Diagonal#Matrices I guess the bottom left 4 elements of a 5 by 5 matrix could be described as a subdiagonal matrix, but I'm not sure the term would be useful. -
WHY DID YOU DELETE MY THREAD???
John Cuthber replied to A Muslim's topic in Suggestions, Comments and Support
Your religion is full of errors and I would like to change it. -
yes it has: it also can't work. It is difficult to analyse something so poorly described but that's not the issue. I cited the proof that it can't work, so there's nothing to be gained from analysing it. If I claimed to have some mathematical proof that pi was about 7 would you need to analyse it to know that it was wrong? That is the sort of claim you have made. You missed something from the summary

There's a clear problem with your concept and it has been pointed out to you. It can not work. It produces no energy. It is a breach of the laws of physics. Not just a breach of the things we know because we have seen them before but a breach of a law that is proven mathematically. http://en.wikipedia.org/wiki/Noether%27s_theorem And yet, even though you have no evidence for it, you think there is something to discuss. There is not. There hasn't been since someone pointed out the problem with this variation on the idea The Taisnierus Magnetic Engine http://www.kilty.com/pmotion.htm

Are you smart enough to you solve mysterys of the electromagnet?
John Cuthber replied to CasualKilla's topic in Engineering
If you have a perfectly conducting coil and a perfect power supply with zero output impedance then you don't get a constant magnetic field- it keeps rising forever. But what actually happens is this http://en.wikipedia.org/wiki/RL_circuit#Current And the field varies with the current. So, the "problem" doesn't exist in the real word- even with superconductors the "magic" breaks down when the field strength get high enough. As for "But we know that DC electromagnets create a constant strength magnet.". Well we know that because all electromagnets have a finite resistance. -
Thank you for clarifying that you don't understand physics.

Why not?

Just in the interest of balance, if you mix ice cold cola with ice cold milk you get a drink that's a bit like a milk shake. In my opinion, it's quite nice. It's also (in my observation) not a bad drink to tackle a hangover. I haven't tried red Bull and milk- I suspect the mixture would be rather acid and would curdle.

So I'm not making an assumption that the plume is even. So your point was an attack on a position that nobody was taking. It was a strawman. You may remember that the point I was making was about the misleading propaganda that people put out about this sort of issue- things like the picture I described as "scary" then pointed out that it was a misrepresentation because the levels it pictured were at worst, tiny. So, once again... OK, prove what you did say. This seems to be a pretty clear claim " 2) Why are you assuming the concentration is even throughout the plume? " prove it. Show that I have made that assumption. Incidentally,, s there anyone else out there who thinks that by saying that Everest is the highest mountain, I am assuming that the world is flat, or do you have to be Overtone to take that viewpoint?

Unknown Spectral Lines in Sunlight
John Cuthber replied to EdEarl's topic in Astronomy and Cosmology
Those are emission lines. The lines from the Sun are (generally) absorption lines. The potential for overlaps of the lines also makes it impossible to index some of them.
