What is the difference between Theory and Law?

In summary, the conversation discusses the difference between theory and law in science. The main points are that a law is a readily observable fact, while a theory is an advanced hypothesis that has been tested and can make accurate predictions. A theory can never become a law, and may be replaced with a better theory if it is disproven. The order of operations is used as a law in legal and commercial transactions based on the proven theory behind it.

What is the difference between Theory and Law? As we all know, Theory is the most fundamental in any subject. How is it important? How is it useful?
Can you give me one example to understand " The importance of Theory "?

To my understanding.

Theory is the result of a:
postulate, that leads to a logical conclusion.

The postulate may be a given.
You remember the given postulate, right ? Given. :approve:

Law is a system of judgement. So law is concerned with the entire proveable theory. If one person see's the theory is true, a set, or order, or collection of people establish a Law.
Like your read addition and subtraction from left to right. See ?

String theory may be a law. But nobody can see that yet, so the theory isn't law yet, and people can't base a set of rule or order of people on it.

EngTechno,
(Please forgive the size of this post.) The definitions of "theory" and "law", in science, are as follows:

A "law" is a readily observable fact about something. It is something that is obvious and undeniable. Allow me to clear up a common misconception right now, laws are not a "higher" stage than theory, and no theory ever becomes a law. Laws are simple and obvious statements about a phenomenon that never require a second guess, or an experiment, to verify them (for example, there is a law that states that there exists an apparent attraction between all objects having positive mass...it's called the law of Gravity, and it's not just undeniable, but it's readily observable and demonstrable (by virtue of the simple fact that you are not floating about, but are anchored to the Earth)).

Now, a "theory" is an advanced hypothesis. An hypothesis is a plausible, testable explanation of how a phenomenon works and/or why it works that way. Once an hypothesis has been tested repeatedly, under a variety of conditions, such that it is sufficient to convince a majority that the hypothesis is probably right ("right", in this context, means that it can be used successfully to make predictions as to how the phenomenon will behave if one conducts the same experiment(s) again), it can graduate to "theory", but it is still tested just as vigorously.

A theory can be "strong" or "weak", depending on the amount of evidence there is that agrees with it, the amount of accurate predictions it's made, and the amount of experiments that have been conducted and have concluded in its favor. However, it doesn't matter how strong a theory gets (you might think of such as examples as the theory of Evolution, Relativity, Quantum Mechanics, &c), it never becomes a law. That would run contrary to the definition of "law" as readily observable and nor requiring experimenation for verification. Also, a theory may always be disproven, but it must then be replaced with a better theory.

Oh. + we teach the order of operations because we see this readily apparent law, and use the order of operations law to allow fair commerce and legal rule of that n stuff.

I didn't know that. Please elaborate on what I added to your words. About how if what you said is true, we all know the order of operatins, and yet we are taught that very thing. Even have to remember it when doing problems.

I don't understand the question. Could you restate it please?

I will try.

Law is a system based on complete theories.
The order of operations is a proven theory, that law accepts as proven, and so uses it to govern - money, resources, and such.

Your saying that law is readily viewable, and in no way based on proven theories. Then how can the above be ?

When you say "Law", are you referring to the laws of a government, moral law, or scientific law? They are very different concepts.

The "law of the land" (so to speak) is based on numerous theories, but it is of a completely different nature than a scientific law (e.g. the Laws of Thermodynamics), which is a plain observation.

Man. Don't get me to repeat myself. That can lead to numerous such requests and replies. Good greif.

The law that uses the order of operations is
A) Governments, and their institutions.
2.) Theories that do not use or need the theory of the order of operations ?

? :confused:

You don't get my jibber jabber on this thread ? :rofl:

Well. Do you want to hear that again ? :yuck: :confused: :eek:

They would appear to be equivalent. So why do we have the laws of thermodynamics instead of the theory of thermodynamics? Why not the law of relativity? Probably a matter of terminology from one century to the next.
 

What is the difference between Theory and Law?

The terms "theory" and "law" are often used interchangeably, but they have distinct meanings in the scientific community. Here are the five most frequently asked questions about the difference between theory and law.

What is a scientific theory?

A scientific theory is a well-supported and widely accepted explanation for a natural phenomenon based on evidence and experimentation. It is a comprehensive framework that explains and predicts observations. Theories can change and evolve as new evidence is gathered, but they are generally accepted as true by the scientific community.

What is a scientific law?

A scientific law is a statement that describes a natural phenomenon or relationship between variables that has been repeatedly and consistently observed. It is a concise and general description of how nature behaves, and it is supported by a vast amount of evidence. Unlike theories, laws do not attempt to explain why a phenomenon occurs.

Can a scientific theory become a scientific law?

No, a scientific theory and a scientific law are not interchangeable terms. A theory cannot become a law, and a law cannot become a theory. Theories and laws serve different purposes in science, and they are supported by different types of evidence.

Which is more important, a scientific theory or a scientific law?

Both scientific theories and laws are essential in understanding the natural world. Theories provide explanations and predictions, while laws describe and summarize observable patterns. They work together to help scientists understand and make sense of the world around us.

Why are there sometimes competing theories and laws for the same phenomenon?

In science, theories and laws are constantly being tested and refined as new evidence is gathered. Therefore, it is not uncommon for there to be competing theories and laws for the same phenomenon. This is a normal part of the scientific process and helps to drive further research and understanding.
