Thanks Stefan, for this post. I left Frankfurt around the time FIAS began to come into life. Despite the fact that I personally would have liked to see more effort into the direction of theoretical physics specifically, I have to admit that I've been very impressed by the foundation of that institute. However, I guess it will take some more time to see whether the interdisciplinary research can be considered successful. Best,

B.

Great news, and I like the photograph too!

Hi Stephan and Bee,

I like seeing physics and neuroscience working together as at FIAS.

I see that John at 'Cosmic Variance' has a post 'Billion Dollar Baby' on the CMS which relates to your recent post of Nature and the LHC.

Speculation
Solenoids maybe a means of conceptually relating the various forces, including gravity.

See 'Iron Core Solenoid' contrasting air / iron solenoids, each with helical wiring [Hyperphysics, GSU, next to last topic that webpage]

I made a similar comment at the Reference Frame in 'Veneziano & Gasperini: book'.

thanks - in fact I 've made tons of photos, and Bee has chosen these two of them :-)


Dear Bee, Doug,

I guess it will take some more time to see whether the interdisciplinary research can be considered successful.

I like seeing physics and neuroscience working together as at FIAS.

I agree, it certainly takes some time, and effort, to fill such general and vague statements as "study of structure formation and self-organization in complex systems" with definite content, and to establish a really fruitful interdisciplinary cooperation.

My impression was that the best way to start - what they are doing - is to exploit similarities in the methods which are used. For example, some of problems studied at FIAS in quark matter, atomic and molecular physics, and neuroscience all involve the search for clusters in large ensembles of particles, or neurons. So, it's a good start to discuss and exchange ideas about the the agorithms used for these tasks, which may be the same for all at the end of the day.

Best, stefan

Hi Stefan,
how thoughts are created and where thoughts come from, how memory is stored and memories are accessed is clearly cutting edge 'thinking'
almost as topical or ground beaking as whether the soup energy (quark gluon plasma) had mass, or acquired mass as it expanded and cooled.

Whether it be simple impulses or chemical reactions in the brain - or perhaps something more - in essence define and differentiate humans from everything else. Hard to grasp that the memory of our 'complete' individual life experience may be stored in something infinitesimally small.
And yet we feel thing with such intensity, whether its emotions or physical pleasure & pain.

Even more amazing the concept that we may see our whole life flash before us (before our eyes, or behind our eyes). Of course in the movies these 'memory' chips are transplantable, but maybe we only have time to experience one lifetime at a time. Imagine if we had the thoughts we had when we were ten or twenty still floating around our head - not the 'general' thoughts, but the day to day thoughts (of that day or month or year).

I wonder if it is evolution that has defined which 'temporal' memories we preserve, ie those which are building blocks of 'knowledge' and those that are 'repetitive' or 'intuitive' as opposed to those which are passing memories. After all face recognition has to be relevant to what faces look like today, what the faces looked like when we were kids would mean little to us now -

I sometimes find it strange looking at an image when I was young, Yes, I was young once (or maybe twice, lol!). But seeing the picture though I recognise it, and I KNOW it was me, and I can almost put myself in that space and time, at the same time it is almost as if it were someone else - and I had simply being in 'his' head seeing the world thru his eyes.

But there you go thoughts just flow and flow, and if we are not careful it just turns to aimless ramble, as we ramble on.

Hi quasar,

I completely agree - that is one of the deep mysteries in science, and one of the most exciting topics to investigate and to think about!

The FIAS people are cooperating on that with the Max-Planck Institute for Brain Research, where they try to gain data from the brains of cats and monkeys.

If I understand it correctly, results so far seem to indicate that "thoughts" and "memories" may be realized in the brain as patterns of activity of large groups of neurons, cycles of activity that repeat themselves and can somehow be triggered by external stimuli or other cycles. I guess that this means that the "hard disk" paradigma of the brain, and the idea of a "memory chip" you may plug in and out, could be fundamentally flawed.

Moreover, it may also well be that case that the differences between human brains and the brains of other higher animals are only gradual.

Very interesting stuff to follow!

Best, stefan

Hi Stefan,

There is an excellent Nobel Lecture by Eric Kandel [physiology 2000] on memory in the sea slug Alpysia.

"The Molecular Biology of Memory Storage: A Dialog between Genes and Synapses"
