Why in derivation of the equations of continuum mechanics the model of material point is used?

Model material points cannot be used for describing the motion of macroscopic bodies. The derivation of the equations of continuum mechanics based on the use of limit theorems, in which the size...

Can you use equations of motion not for material points but for equations of mesoscopic particles?

In mesocsopical systems, interactions described with action fluxes in a mechanical system are flow of impulse. (See attachments.) Lev

Is there any evidence that different dendrites and/or axons in the same neuron may carry qualitatively (not quantitatively) different information?

We have proposed a theoretical model which might be interpreted as suggesting that individual dendrites and/or axons play qualitatively different roles.

What is the main road leading to the development of AI and its various subfields (pattern recognition, data mining, information retrieval, etc.)?

I propose that the *only* way ahead is via a fundamentally new representational formalism that would clearly reveal what critical information has been missing from the conventional forms of data...

Have you noticed the lack of serious *scientific* discussions on scientific internet forums (and conferences) despite the often repeated "internet opportunities"?

More accurately, I mean not the narrow technical discussions but the discussions on the general direction of the corresponding natural science. And this is particularly conspicuous given the...

What is the *concept* of class in your favorite learning model, e.g. in SVM, ANN, etc.?

My claim is that none of the accepted concepts of class are *adequate*. Is this situation ok? Is this ok to do classification without an adequate (central) concept of class available in the model?...
