I am a college teacher of mathematics. At the age of 63, I still do not

have tenure (that sometimes happens, especially if you alternate careers

inside and outside academia, step on too many toes, make too many mistakes

in interpersonal relationships, etc.). However, I do most of my research

for myself in mathematical fuzzy multivalued logic, mathematical

probability-statistics, mathematical physics, mathematical modeling, etc.,

and I actually develop a lot of it while typing on the internet (belonging

to about 150 internet forums). I grew up on the typewriter, so typing

actually helps me to think more than speaking or other modalities.

I just presented an interesting existence-knowledge differential equation

model on theory-edge@yahoogroups.com, and to go beyond that here I will

simply mention that the logical existential quantifier E (backwards E,

actually), meaning *there exists (x such that...)* can actually be

fuzzified-made multivalued by changing it form a 0-1 (there exists or there

does not exist) variable to the continuous interval [0, 1]. I'm the first

one to do that to my knowledge (see abstracts of 64 of my papers, especially

the last few, at http://www.logic.univie.ac.at - after accessing the site,

select ABSTRACT SERVER, then BY AUTHOR, then my name in that exact order).

The difficult problem is to relate this logical existence to the scientific

concept of existence as in *there exists a star in such-and-such location,*

which assert physical existence (or behavioral, mental, biological,

socicultural existence as part of generalized physical existence). It

appears that logical and physical EXISTENCE, E, can be defined as CHANGE IN

KNOWLEDGE-INFORMATION-ENTROPY (KIE), or alternatively as CHANGE IN POSITION

with rather carefully specified conditions (e.g., with respect to a surface

on which the object is located, e.g., with respect to the surface of the

earth). The change that I have in mind is essentially dK or dx where K is

KIE and x is position with respect to a surface or some analog, but with a

fixed *unit* changed in the *independent* variable one can approximate this

by dK/dt, dx/dt, or more generally dK/du, dx/du respectively where t is time

and u is some variable including possibly time.

This has very nice applications to cosmology (expansion/acceleration of the

universe, inflation, Big Bang), biological sciences (even *viruses* as

intermediate between life and death, comparing organic and life processes

with inorganic processes in terms of amount of change with respect to the

earth or with respect to time relative to the earth, etc.),

information-entropy (see the theory-edge forum site referenced above), etc.

What about issues like quantum/microscopic vs macroscopic, uncertainty vs

multiple worlds, string/p-brane versus quantum field, gravitation vs other

forces? This is where I think progress can be made especially on this

seminar, but I want to know what people think about the topic before jumping

too far into the water so to speak.
