That's a great link, thanks. I laugh at absurdities and bizarreness...which is not always the safest reaction, either.

It is interesting thay we do not need to be in a good mood to laugh when tickled.

I hate tickles as they actually hurt me, in an over sensitive kind of way.

No volcanoes in Switzerland. You don't need a volcano for a hot spring, just geothermal heat. Fun reading here: http://www.mountainnature.com/geology/HotSprings.htm

And a list of volcanoes around the world here: https://en.wikipedia.org/wiki/Lists_of_volcanoes
Just got in from a bbq with the neighbours, and I asked this question as one of them studied geography. She told me there are loads of dormant or extinct volcanoes in Germany, but was unsure of how many there are in Switzerland.

My question is, with so many granite quarries in Switzerland, which is an igneous rock, surely there must have been volcanoes here thousands of years ago?

Re: Ask a Scientist

Nope, there are no volcanos in Switzerland. However some German ones are fairly close, Hegau and Kaiserstuhl come to mind.

Granite is formed within the Earth crust, usualy 2km and more below the surface. Geologic processes may bring the granite to the surface, in this case the forming of the Alps which is caused by the African pushing against the Eurasian plate.

As for the granite in CH, Urs Max is right. More fun reading here:

Re: Ask a Scientist

Can we dream about somebody we have never met?

I had a dream last night about somebody I have never seen before, it was really precise.

Yep. Same here. I think we can.

Dreams are a fruit of the subconscious. We form a picture of someone even before we meet them based on what we know / what we think we know of them. And the subconscious does the rest.

It seems to me that you answered your own question .

However, if you meant: Does the person really exist? Will we ever meet them in real life? Those are interesting questions, but not scientific ones.

Personally, I see dreams as a kind of trash can for thoughts, the result of the mind spitting stuff out while it is disconnected from reality.

Then again, being sure you haven't seen someone before is just as illusory. You may have well seen that person (passing by for instance) just not "register" it. Or you may have met but not remember it. The mind can play nasty tricks on you, don't rely on it for anything serious

Re: Ask a Scientist

Yes, it's called foresight or seeing into the future. Had it happen to me once or twice when I was a kid. And no TheWolverine, I formed no picture of the person from what I knew or thought I knew of him since I didn't know him at all. Never met before, didn't even know he existed.

Yeah, Wolve - I think the unconscious brain work plays a big role in it.

If you take sleep as a thought processing-short memory cataloguing time period (I know this is a relatively short part of our sleep), the images might be a byproduct. Emotions too, desires, regrets, or whatever other feelings are attached to thoughts and stimulate/accompany them.

I might have seen him in passing, or liked him without getting this info fully into my conscious register, if it was 2sec moment, or something.

Or, it might be a collage of everything I ever consciously liked on everybody..who knows.

The fun dream part was the conscious feeling of positive affection. So concrete, and everything with it, the smells, the tone of voice..Why do we dream about abstract beings when we do not have the experiences really, with them?

Before people find somebody, do they know they are looking (I do not think I am, tbh), do they have a concrete picture they are unaware of, and then somebody irl walks in and just matches it? How does this image change with age..and why even have this in a dream. I do know how to program to dream about something, can have a series of nights, continuing my dreams - loads of people can. Kids are better at it, imho. But this was completely unintentional. I have never seen the person, no idea what language he spoke, either.

Interesting. I had a dream in February like that .... I woke up and I knew that I knew that smile. I searched amongst everybody I know ... no luck. I still wonder sometimes and I dream a lot, so I don't usually keep them in mind that long including all the sensations but I can recall every detail still today.

Who knows, I might walk into that smile one day .... I wonder how that would be.

That may well be the case marton. All I know is that I had 2-3 dreams when I was younger that eventually came to pass. I had no sense that I was experiencing them in real life until suddenly I'd get a "deja vu" feeling and realised I was enacting something I'd dreamt about months or maybe years before.

Re: Ask a Scientist

Most people around me have experienced it, including me. I think it relates to recognising preconceived and altered (in our minds) stimuli that makes us feel that it is familiar, in some ways. I think it is normal, in fact. Like a reversed situ - dreaming of a person I have never met (I shouldn't dream of him, right), is not just a trick of phantasy/imagination, creating that "photo" in my sleeping mind. It is most probably preconceived but unconscious image that resurfaced, or a mix of them, creating an illusion of "newness". I most probably ran into him, saw a glance or actually know him. I primed myself somehow.

Coincidences happen mich more often than we think. In the case of deja-vu from a dream, you need to take into account that we all dream dozens of times each night, most of which we're completely aware of when we wake, but which have, nevertheless, imprinted an unconscious memory. Years later when a similar event takes place the brain will automatically access that memory as it records the new current one, and this will lift it to the conscious level, but only those parts of those dreams that fit the reality you're now experiencing.

No, it wouldn't. His point is that time is another dimension, with similarities to the spacial dimensions we're more familiar with. But just as we can't occupy multiple spatial positions, so we're also tied to a given point in the time dimension.

In my view, any belief in precognition can only be based on the idea of a supernatural realm or entity of some sort. Trying to find a scientific theory to support it is therefore as likely to succeed as a scientific proof of the existence of god(s).
