Oh no - that will probably happen too yes Global catastrophies are like buses - you wait for 30 million years and then two come along at once...

Breakthrough as US researchers replicate photosynthesis in laboratory

Scientists have made a fundamental breakthrough in their attempts to replicate photosynthesis – the ability of plants to harvest the power of sunlight – in the hope of making unlimited amounts of "green" energy from water and sunlight alone.

The researchers have assembled genetically modified viruses into wire-like structures that are able to use the energy of the sun to split water molecules into their constitute parts of oxygen and hydrogen, which can then be used as a source of chemical energy.

If the process can be scaled up and made more efficient, it promises to produce unlimited quantities of hydrogen fuel, a clean source of energy that can be used to generate electricity as well as acting as a portable, carbon-free fuel for cars and other vehicles.

My dowsing was really an accident.  There were some men excavating a large area in a field, and they did not want to break any of the field drains.  Apparently, the local dowser (I didn't know there was one) had gone off somewhere and they were standing around wondering what to do.  One of them had cut two pieces of fence wire into similar lengths and had bent a smaller section of the lengths at a right angle, more or less to form a handle.  He was wandering up and down and scratching his head when I arrived.  I laughingly said .... let me try .... the most amazing thing, the fence wires almost jumped out of my hands.  I don't take any credit for this - I have no idea how it works, but I've been successful every time I've tried, which, admittedly, is not many.

I have not seen the author Jean M Auel, but will have a look on Amazon and see what they say ... thank you for the tip.

What were your articles about?

Also, I think that men, when they retire, are quite often looking for something stimulating to do and if they help with the domestic chores then there is more time for both to go out and about.  I know one retiree who is busily teaching himself to cook .... he is ALWAYS scrounging recipes from me ... I think it is great that he is doing this.
Dowsing debunked.

Welcome back to Dizzy Daisy.  yay  yay

And she's barely back with us when she's pounced on by the Great Sceptic of MW! Smile

That's your academic intellectualising at work James.  Why can't you accept that there might just be some truth in anecdotal, i.e. unpublished, evidence?  If man had had to wait until evidence, theoretical or empirical, could be set down in writing or in print, and the results testified to several times over before it could be considered valid, then he would never have evolved.  Also how do you explain why much published scientific or medical evidence is debunked and in some cases found to be enitrely incorrect and therefore misleading?

It has nothing to do with "academic intellectualising", so spare me the ad hominems. Extraordinary claims require extraordinary evidence, Aileen.

Moreover, anecdotal evidence is notoriously unreliable. Do you realise what we would have to consider as fact if we simply accepted anecdotal accounts? I'm interested in what's true. I am not interested in giving people the benefit of the doubt when it comes to things that run contrary to all available evidence.

Do you think the people in the video I posted are any less sincere about their beliefs than Daisy?

You'll have to be more specific. Mistakes are certainly made. However, they are corrected as a result of further research, not by anecdotal evidence. I'm open minded, but why should I believe claims that have been debunked consistently? And it's not just about any scientific evidence. It depends on the type of evidence. Double blind testing is inherently unbiased and is very reliable. Little in the way of interpretation is required.

A claim doesn't have to be set down in writing and tested empirically for me to decide whether it is plausible. If there is no available evidence or the evidence is sketchy, I'll remain open to the possibility. There is a difference between being open minded and being gullible. To paraphrase Richard Dawkins, I like to be open minded, but not so open minded that my brain falls out.

There are a great many things that James says that I agree with BUT not this one. I can't feel the earth energy through the stones and other people can, most definitely, but that doesn't mean I think it doesn't exist - I'm sure it does - and the same with dowsing, some people simply have the ability/gift or sensitivity to be able to dowse etc. I can't see electricity or radio waves but science has proved that they exist and we use them to our advantage today and as far as I am concerned  an open mind is needed to accept that certain things are possible even if we have not yet discovered how or why.

It may be that way back through the millennia - when man was still essentially an animal - we had far more natural faculties/sensitivities, as animals still do today and that as our more technical senses, such as speech and intellect, developed then the more natural instincts waned until many of us lost them altogether. Daisy, I envy you your ability - it is a natural thing - maybe you can find a way to put it to good use.

Daisy you asked what my articles were about. Dartmoor Magazine is coming up for its 100th issue (it is quarterly) and I have every copy except No.1. In later years I have written for it many times - this article was about its early contributors and all the informative things they wrote about. Lots of humerous anecdotes too. The other is a Legends article centered around a very ancient grove of stunted oaks which have been on the more since William the Conq. Supposedly a devil huntsman rides forth with his demon hounds to hunt the souls of unbaptised children (a legend common throughout the Northern hemisphere) plus of course the possibility of the grove being used by the Druids. I've done now and can go out an enjoy myself for a while.

Yes, science has proved that they exist. It hasn't proved that dowsing works. On the contrary, dowsing has been debunked more than once. People will believe what they want to believe. No matter how much evidence there is to the contrary, people will generally refuse to accept that their beliefs are flawed. Just look at the video I posted. Even after failing the double blind test, the dowsers refused to accept that they were wrong. People have to learn to accept inconvenient truths.

Dowsing debunked.
May we have that in writing please, so that we can take quotes? How can Dawkins debunk something he's never seen, like Daisy in a field holding wires? And if Daisy's carried out the experiment and got a positive result how can anybody say she didn't?

I was wondering when you would post that!
Does he make a habit of it?

Had to be done. I hate it when people give anecdotal evidence.
Does it give you a pain? You’ve got me in stitches. roflmao What’s painful about anecdotal evidence?

Yes, science has proved that they exist. It hasn't proved that dowsing works.

If it works for Daisy how can she stop believing it? That would be to disbelieve the evidence of your own eyes, wouldn't it?

Is that all the video shows? How can that be applied to all instances?

Daisy didn't do an experiment. Like the dowsers in the video, I don't doubt her sincerity. Also like the dowsers in the video, she would fail a double blind test.

Yes, I make a habit of debunking nonsense.

I didn't say it was painful. I said that I hate it.

Someone sedate George.
