General Science / Re: Is cold fusion possible?
« on: 16/12/2006 23:11:55 »
Yes, quite exciting but best not hold your breathe. According to the register it won't be up and running till 2015 and they're unlikely to have worked out the design for an actual power plant till 2035! http://www.theregister.co.uk/2005/06/29/france_fusion_win/

Cold fusion would be the business but, AIUI, the problem is getting the nucelei close enought together against charge repulsion unless they collide at fantastic speeds (ie high temperature)  [:(]

I guess the equation would be our lifespan divided by infinity, in otherwords that chance is infinantly small, or that thought (which is assumed by everyone) is impossible........

...... eventually the right amounts of carbon nitrogen oxygen hydrogen etc will collect on earth, the sun will burn just hot enough and you will exist once again, even if it takes a trillion trillion trillion trillion years.

So thats how I know einstein, me, you, and george washington cant truely die. They existed once, and they will exist again......



Interesting argument but IMO it falls down by assuming too many infinites.  

I'm not sure whether time will end or not but I do think there is a finite amount of energy/matter in an expanding universe.  Therefore eventually, in fact quite soon by your timescales, there will be no suns and therefore no life as we know it (Jim).  

Probably no matter either in the 10^48 years you estimate this might take to come about, the half life of the atomic neutron is thought to be less than a trillionth of that! http://hyperphysics.phy-astr.gsu.edu/hbase/particles/proton.html

I feel that it is worse but that is just a personal impression based on stories like falling applications for science courses, the closure of university science departments, shortages of funding for space research and so on.

How much of that is down to the government and how much to other agencies or just fashion is hard to say.  Certainly the higher top-up fees for science courses can't be helping, nor the ever increasing disparity with salaries paid to lawyers, financiers, footballers, TV presenters, estate agents and politicians* [:D]

I believe, just like the rest of the human physique evolving into different shape and size, when affected by external factors over long periods of time, so does the brain. With increasing demand on information intake and learning process, the brain must be developing to  adjust to larger storage and processing capacity.


Do you mean "evolving" (ie changing over generations through mutation and selection) or development through exercise, like body building?  

Personally I don't believe there has been any measurable evolutionary change over the period in which intelligence has been attempted to be measured.  Nor can I see any evolutionary mechanism that would favour greater intelligence in the modern era that didn't exist in the past. If you're smart enough to walk and breathe at the same time you've got as much chance of surviving and passing on your genetic material as anyone else. [:)]

However, I am willing to believe that our ability to think improves with practice and that this might be reflected in changes in the structure of the brain.  I have seen some evidence to support this idea,  although only in the press (off duty I avoid scientific literature like the plague, which in many ways it resembles).

Is that the necessarily true?  I can't think of any fundamental reason why the genome should not contain survival critical knowledge as well as other information.

I had a quick rummage through the internet after reading your question and most sites tend to call this kind of thing "instinctive behaviour patterns" - but, as you imply in your question, some of these seem to require a good deal of information to work.http://www.a2zpsychology.com/psychology_guide/instinct.htm

Recently I was wondering how much space on the Internet is being used up by people who have passed away. Pages and pages of email accounts, retail web page accounts, blogs, photo gallerys, posts in forums etc etc that will never be used again.


Never mind the dead on the net,internet storage is now of a size that a lifetime of human sensory input could be stored - chuck in a bit of processing power and maybe you, or something based on you, could "live" in there!  

Now that's scary![:0]  But kind of interesting too [:)]

Maybe we are!  The big bang fits that description of a white hole mostly and since all matter, energy, time and space flowed out of it, the universe could be described as still being in it.  [:)]
