Sensory receptor nerves respond to external stimuli like light and sound. These are exteroceptor  nerves. This defines what we mean by the concept "to feel." Sensory receptor nerves can also respond to internal stimuli like blood pressure. These are interoceptor nerves. Perhaps what we call qualia are the triggering of other interoceptor nerves, nerves that respond to various other types of internal stimuli. Again, they are what we "feel."

Legacy code

I have code and printout dating back into the 1970s. Most (all?) of the oldest electronic files will no longer run but I have hard copy of many programs. I have been unable to locate a couple of thick file folders of publications on case-based reasoning which also contained the first CBR programs I wrote. I suspect that these may have been discarded by mistake a few years back when there was a remodeling that tore the outer wall off the science hall (and my office). I've written too many hundreds of programs to want to spend the time needed to preserve them all.


I have been asked about my worldview. Many of my blogs on philosophy deal with my weltanschauung, among them my blogs of  1 sept. 2012, 17 aug. 2012, 1 Jan. 2012, 17 aug. 2013, 1 dec. 2014, 26 march 2014, 13 april 2015, 20 feb. 2015, 4 oct. 2016, 15 sept, 2016, 22 april 2016, 28 may 2016, 1 june 2016, 21 july 2016, and 7 Jan. 2017.

A.s.a. H., reflexes

In Asa H, as in humans, there are typically far more input signals received as compared to output signals generated. Output predictions/generation may then occur on higher levels in the memory/concept/abstraction hierarchy, i.e. "downward causation." What outputs are generated quickly, confined to the lower level(s) of the hierarchical memory, this constitutes "reflex."

In my 1 October 2015 blog I said: "In some cases we would like to have additional definitions for a given concept." I now find that for most named concepts I would like to have multiple examples.

I'm working to simplify my Lego robot designs. This will allow for full coverage with the pain subsystem while reducing the total number of sensors required.

Some of what's wrong in education rests with the students

1. Some students we get in physics courses should not be trying to do physics.
2. Most students should be trying to attend all of the scheduled classes.
3. Many of our students don't put enough time and effort into their classes.
4. Some students want ME to do work that THEY should be doing.
5. Students should not be expecting me to entertain them.
6. We should do things that are important because they are important, not because they are "fun."

 The paper in the April 2017 American Journal of Physics (volume 85, page 311) is a spoof but one day we may be able to objectively demonstrate that a given course TEACHES effectively* and when a given human student does poorly then it's THEIR fault.

* by having an AI take the course and learn the material successfully
