I do not know of any other math or physics equation that places numbers in association with a set. And the Uncertainty Principle to me places Planck's constant as a number for angular momentum in connection with two sets of the del_position and the del_momentum. You say that there are other such equations. Well, I know of no other such equation where it has sets and numbers strewn into the equation. Seems to me, that an Equation has to be all or no sets, and all or no numbers. But to have an equation that is parcelled with both sets and numbers is hard to understand. You say the Uncertainty Principle is not a unique equation. I say it is. And even the new principle of the Geometry Principle which I contend is the inverse of the Uncertainty Principle. Geometry Principle: Eucl geometry == Elliptic geom unioned with Hyperbolic geom Even that equation involves three sets, unlike the Uncertainty Principle which involves two sets and a number. So, thanks for asking the question, because the way to resolve it is that neither the Uncertainty Principle nor the Geometry Principle are equations for there never is a equal sign in there, and what there should be is a "greater than sign >" in the Uncertainty Principle where it can not be equal and where the Planck constant is singleton set having only one member {h} and where this set is smaller than either the position and momentum sets multiplied or intersecting and where we have a "order on sets with more than one member". As for the Geometry Principle, there is no equation but rather an equivalency relationship which I write as "==" So if you are aware of more, or other equations or relations in math or physics that has a mix of sets and numbers, please inform, for I know of no others, at least, important others. > At any rate, it is not the case that probability is a subset of > algebra, or algebra is a subset of probability--the two fields are > independent, use different methods, and answer different questions. > No, I have a different opinion. My science mind tells me that Physics is top, and that means all the other sciences are subsets, so we can place in a hierarchy list where chemistry is closer to physics than say geology and that biology is closer to physics than is sociology but all of these sciences reduce to what the physics is going on. And that logic also says that every math subject falls into a hierarchy of subsets, and every physics subject also falls into a hierarchy of subsets. The heart of math is probably the dual pair of geometry and numbers. Algebra fits somewhere as a subset of numbers, same with probability theory and set theory. The question is whether probability theory is closer to Number theory over that of algebra and over that of set theory. Example: chemistry is closer to physics than is biology or geology. So that we have Quantum Mechanics as the heart of Physics and where thermodynamics is a subset of Quantum Mechanics and where Maxwell Equations and electrodynamics are each subsets of QM and where each of these fit as subsets, whether one is closer to QM than another is fun to find out. > I also do not know what you mean when you write that "velocity is a > semigroup and that acceleration is a group and the a force is a ring." I was making an observation. An observation that noone in mathematics ever addressed the question why is Algebra so filled up with group, ring and field when it was first borne by Galois to solve the quintic and so, why is modern math so saturated with this group ring and field speak? So no mathematician ever squarely faced or answered that question. But I have answered it. Math is a subset of Physics, and so, where in physics is this structural importance. A group, ring and field is no more than a classification-structure. We define a structure like a group or a ring. It must meet specific criteria. Then we can make deductions. So if math is a subset of Physics, then physics must have these "classification structures" just like math. And it is not far to look into Physics to see where classification structures exist. In fact, probably the first day in a Physics class you learn a few structures: You learn mass is "m" and that length or distance is "d" and that time is "t", but then in advanced physics you get some bigger structures of F = ma, or acceleration is m*s^-2, or pressure is dyne*cm^-2 or density is g*cm^-3 or resistivity is ohm*cm, or angular momentum erg*s Each of these structures in physics, the units of the definition, are the same structures that Algebra gives to calling a semigroup or a group or a ring etc etc. So on one side of the table, a physicist playing around with momentum, force, energy, inductance etc etc, is the same thing as the mathematician on the other side of the table playing around with groups, rings, fields. Both are playing with classified structures in their science. Now do not hold me to saying that a force is a ring in physics. That was never my intention. What I was trying to say is that all the structures of physics of their parameters, is similar to the mathematician with all his structures of algebra. Do not think that a force is a ring, but rather, think that the entire spectrum of group ring and field is the akin to the entire spectrum of physics unit-dimensions. And obviously, noone can do physics without doing these unit- dimensions of Force =ma and that is why Algebra group ring and field keep cropping up all over the place in math. And why noone before me could ever explain the above, because noone before me ever realized that Physics comes first and explains all of mathematics in its proper perspective.
