Comment Re:Doubt is justified (Score 1) 1747

See Halton Arp's observations of the redshifts and angular correlations of quasars. Since he started this work, it has been corroborated by a vast body of additional observations. A good overview is given in his book [amazon.com] "Seeing Red".

And an even greater body of evidence against or possibly for? The point is that science which is contentious is at the limit of our understanding. To say that Dr Halton Arp's observations falsify the big bang is almost absurd. That is because there are many lines of evidence for the big bang. Yet despite this it is still not certain and maybe a better theory will come about.

In discussions like this, a considered opinion would present both sides, weigh the evidence and possibly come down on the side which seems most likely. In the debates on the Internet and in the media we get one side and then the other simply shouting the other is wrong.

It is good to see in this thread people discussing what a skeptic is. Unfortunately the term global warming "denalist" seems to fit too many peoples view. It is absolutely fine to doubt humanity is causing significant climate change but when people accuse the scientists of cherry picking data, of bad science and bias it sometimes makes me cry to read these people's reasons.

a) the Yamal tree-ring data [telegraph.co.uk] - data from 10 trees is extrpolated into a 'trend' and finds its way into a number of papers

Well according to Steve McIntyre, "It is not my belief that Briffa crudely cherry picked. My guess is that the Russians selected a limited number of 200-400 year trees - that's what they say - a number that might well have been appropriate for their purpose and that Briffa inherited their selection".

If you want to have a reasoned opinion on climate change and the data it is best not to use James Delingpole as your source. Simply put, Steve McIntyre did not like 12 trees used for the 1990 temperature so used 34 other trees from nearby. Can you do that? Simply take the growth from one area and directly compare to another?

b) CRU emails - won't say much more, too much said about this already.

Agree :)

c) New Zealand average temperature graphs [telegraph.co.uk] - high-school style 'cooking the graph' to match expectations

Maybe or maybe not. I agree that the temperature corrections look rather dodgy. If the data did show that New Zealand was not warming while the rest of the globe is warming, would that invalidate AGW? There is a lot of data out there, most of it considered good science. A few blips here and there do seem to be taken too mean more than they should.

Comment Re:And FTL, too (Score 1) 575

Almost, one of the proposed solutions to the EPR paradox was hidden variables. Thereby showing that QM was incomplete and proving Einstein and presumably Podolsky & Rosen beliefs that QM was not wholly correct. However experiments to prove/disprove Bell's Theorem have shown that local hidden variable theories can not replicate QM and therefore observed physics. Therefore a hidden variable theory would have to be non-local, allow some sort of FTL communication. The particles have some sort of FTL concurrence but no information can be transmitted with this.

OR the theory could be local but not counterfactual definitent. So we are left with either theories which are non-local which seem to suggest special relativity is incorrect (Bohm interpretation. Or QM particles do not have definite physical property like momentum unless you measure them (Copenhagen interpretation).
This is why people think QM is weird.

(Swine Flu) A virus that was super-contagious and infected nearly everyone,

... except that H1N1 isn't "super contagious" - it's not even as contagious as regular flu. The hype from Mexico was wrong - of the 152 people who supposedly died from it (which is what made people thinkit was highly contagious), revised figures showed only 7 actually did.

The big lesson here is don't listen to Fox News and CNN, and don't let Fox News and CNN dictate government policy. (And I'd blame WHO and CDC for part of this as well - they have a financial and institutional interest in keeping the hype going well after it was obvious it was mostly bullshit).

Well the WHO say that it's about as contagious as normal flu. Most experts are likely to say we don't quite know yet but it looks like it is about as contagious as the seasonal flu. H1N1 is not as virulent as first thought and does not seem to have got worse in the northern hemisphere flu season as feared. We should be happy! I can't see how whether 152 or 7 died has much to do with how contagious it is. Your reply to gilleain does not really make much logical sense,the only figure which would matter is how many caught the virus.

Comment Re:What Do We Know? (Score 1) 775

I think there is no doubt that counterfeiting will be stretched to include copyright infringement. The reason is simply that most/all? western countries have lost a lot of their industrial base. It is cheaper to use lower paid workers in countries with lower standards of health and safety. Therefore what can these countries do to fill the gap? Many of them see content creation and advanced knowledge as the new industries which we can out compete poorer, more populous countries.

However there is one problem with this and that is knowledge and information are easily transferable, a CPU design or film is easy to share throughout the world. Only a strong legal framework and enforcement could stop such a natural and easy process. As "stealing" information is so easy to accomplish expect harsher and more desperate laws over the coming decades regarding "IP".

Until they eventually work out it won't really work. [cry] This new treaty as has been described by Geist is a natural progression from what we already have through TRIPS and WIPO. Typical politicians, when laws they make did not have the desired consequences, make harsher and many more laws!

This sounds so cool. I dreamed of such a device when I delivered newspapers, especially on Sundays when only a few papers filled my bag. At the time I imagined delivering the content as memory chips, this was before most people had a mobile phone. The question I have is who in Apple has these ideas? It sounds like something Google could have done, or even Microsoft.
