So you actually do agree with me that you better define NEW words to avoid ambiguity?
Or why don't you use the unambiguous definitions of science instead of layman's language?
The mainstream definitions are all ambiguous and/or circular. The defs Gaede and I propose resolve this.

Just compare the definition of "object":
WWW wrote:
- In physics, a physical body (sometimes called simply a body or even an object) is a collection of masses, taken to be one. For example, a cricket ball can be considered an object but the ball also consists of many particles (pieces of matter).
- In mathematics, a category is a fundamental and abstract way to describe mathematical entities and their relationships
- In philosophy, an object is a thing, an entity, or a being. This may be taken in several senses.
- a tangible and visible entity; an entity that can cast a shadow; "it was full of rackets, balls and other objects"
Not very clear, except that in physics it might be interpreted as something with mass.
Yay synonyms! Object=mass. So what's mass? A relationship (vis a vis gravitation?). A relationship amongst what, objects? But an object is mass. Circularity.

With that of "vector":
WWW wrote:
- In elementary mathematics, physics, and engineering, a vector (sometimes called a geometric or spatial vector ) is a geometric object that has both a magnitude (or length) and a direction.
No ambiguity, just two well defined attributes.
Vector: Length and direction
Length: extent of an object
Object: mass
Mass: Relationship amongst objects
This is the problem with defining objects. It always results in circularity. The word object refers to whatever has shape, i.e. a boundary. That is why we POINT to objects, it is the only way to avoid circularity.
*points* THIS is what I'm talking about. Done.

How can an object be defined as existing without observation and only what you observe? What about objects that exist but cannot be pointed at? Take an electron for example...or an imaginary "thread" if you prefer.
Since when did I say that objects are only what you observe? Why do you keep equivocating?
I have highlighted where you state that in
red.
I said the object you see is exactly what you see before you. You have a problem with that?
I hate running around in circles...for me pointing to a model of an object is not the same as pointing to an object. Pointing to a picture of a TV is not the same as pointing to a TV. It lacks the sound and moving pictures
altonhare wrote:Yes, it's invisible. The first step in the sci meth is to propose WHAT it is. This is the step everyone skips. They wanna go straight to describing (forces, velocities, etc.) before they have even presented WHAT they are describing. You can play with equations until they match observations accurately all you want, you cannot explain a single phenomenon of Nature until you present something on the big screen for all to see.
The scientific method starts with observations, then a hypothesis is developed that makes falsifiable predictions and these are rigorously tested for repeatable results. There are a million theories for the big screen, but most of them already fail to simply predict the repeatable results of mainstream physics. If they can't do all of that and make new predictions they simply stand no further chance than some casual presentation and discussion in a corner of the web.
Wrong, you confuse science with brainstorming. Brainstorming, pondering, contemplating, researching, etc. may start with observation. Until you have formulated a hypothesis, you do not have a scientific theory, you have not begun the sci meth, and you're not doing science. Until then, you're just guessing, conjecturing, trying to find inspiration, finding patterns, collecting clues, etc. You're a detective at this point.
When you feel like you've done enough detective work and have developed a rigorous theory and convincing evidence, you formulate your hypothesis. NOW you're doing science. You point at something, THIS is what I'm talking about when I say "electron". Then you explain some phenomenon, like how the electron "quantum jumps" or how it jumps from atom to atom in a circuit.
Science has nothing to do with predictions, sorry. That's what fortune-tellers and astrologists do. Nobody knows what will happen in the future. Science *exclusively* explains consummated events. When someone takes a guess and it turns out right, we call it intuition, a hunch, a good guess, etc. If we sit you on a hill for 20 years and you guess things all day long the whole time, chances are at least one will happen. Are you doing science?

To say it differently: the "Grand Unified Theory " is mission impossible at best and should be considered to be nothing more than entertainment. But it is great entertainment. Many people dedicate their time or even lives to it.
It is entertaining because it mostly sells science fiction and fantasy. What it puts on the screen, in order to sell the theory, has zilch to do with the actual "theory" and is practically all supernatural or even irrational. String theory has no hypothesis. The supposed "theory" dies right there in the cradle. They cannot show us their "1D string", nor even a model of it, so we have absolutely no idea what they're talking about when they try to explain some phenomenon. It's a complete non-starter.
Quantum proposes the particle, a ball. But it only pays lip service to the particle.

I may deceive myself into thinking I understand, especially if many of the same words are used over and over in "science" classes from an early age. Unfortunately just stringing strongly associated words together is not science. A scientific theory consists of a physical explanation that we can all visualize and illustrate. Now we can understand what we're talking about.
Humans have a strong liking for visualization since 80% of our brain is dedicated to the visual function.
As that function is hardwired for survival it is just not always that objective. That is why formal mathematical models are the language of science. This method is unfortunately orders of magnitude slower than some nice pictures, but it fulfills the requirements for falsifiable results. A picture of a rope is entertaining but not very useful for predicting the heat capacity of copper.
Again, prediction has nothing to do with science. Nobody predicted the cp of copper. Researchers MEASURED it, then someone found an equation that CORRELATED it. This equation may have happened to work well for other metals too. Good job. That's not science. At best that is research, i.e. detective work. It may give us a clue, i.e. it appears that all metals behave similarly in this respect. This implies to the detective that they have similar structures, and other clues may help the detective propose this structure. When the detective is confident s/he presents the hypothesis: *THESE* are metal atoms, and s/he points to atoms that are malleably joined in some kind of extended balloon structure. The detective-turned scientist now explains how the metal interacts with other objects/atoms to produce the observed behavior, such as cp, conduction, etc.
At the end, the scientist presents all the evidence s/he collected while in detective-mode. All metals follow this basic pattern *presents equation*. The scientist then points out particular aspects of the equation that led him/her to posit the extended structure. The scientist presents data showing how metals all behave similarly in this respect, and all have the same maximum cp. Perhaps s/he can even show how the equation corresponds in some what to an extended structure, further convincing the audience.
The evidence gathered can be interpreted in many ways, its main purpose is to convince people that your theory is Right, by making it look like the evidence is best interpreted your way. The evidence comes last however, because science first cares if your theory is rational. If it's irrational all the evidence in the world can't save you! If your theory is that love binds the electron to the proton, it doesn't matter how much data you gathered or how many equations you developed. Your supposed "theory" dies in the cradle.
