what is the importance of measurement in the development of physics?

Historically , before Descartes, philosophers  thought you could understand the world only by the power of thought. Descartes realised that experience is critical to science. After everybody applied that physics developed exponentially. Without measurement we can never estimate or calculate how different things influence a certain phenomenon. So...wright now experimental data is critical to physics. Also, because nature is so complicated, even if we now basic laws, they won't help us much in determining something that occurs in the real world.

Direct measurement will be correct.\nPeople can be mistaken, or lie.\n\n;-D Where did you not learn to spell? Wow.

science people say so...\nbecause with measurements, everything is quantized.... and if something can't be quantized, like ghosts, then they are not real, or of no interest...\nbecause science people are interested with matters of consequence...

What does it mean to be "true"? The quantum theory (I suppose that's what you're asking about) can explain a lot of physical experiments, so, up to a certain extent, it has been proven true. It is also the truest physical theory for small scales up to today.\nScience isn't about finding absolute truths, it's about providing a description of reality that suits your needs. Take newton's gravity laws for example: while proven false in absolute by einstein's relativity, they are still really useful and tought in many places.\nOf course the goal is to one day provide a theory (a description of reality, not "a guess") that explains everything, but for now that's still a dream.

Anthropometry (Greek ανθρωπος, man, and μετρον, measure, literally meaning "measurement of humans"), in physical anthropology, refers to the measurement of living human individuals for the purposes of understanding human physical variation.\n\nToday, anthropometry plays an important role in industrial design, clothing design, ergonomics, and architecture, were statistical data about the distribution of body dimensions in the population are used to optimize products. Changes in life styles, nutrition and ethnic composition of populations lead to changes in the distribution of body dimensions (e.g., the obesity epidemic), and require regular updating of anthropometric data collections.

He basically invented what has become known as classical physics.  It is accurate and can be used in most areas of science today, however, it does have its limitations.  Which is where modern physics comes into play.

well, I'm afraid that physics is everything around you, have you noticed the word "physical"? simply physics is the reason there's a daily life to talk about in the first place, physics is used to make the PC you are using, the monitor you are looking at, the speakers, the satellite for communications and GPS systems....etc.\nAlso, physics isn't only about electromagnetic and stuff.... mechanics is also physics, aerodynamics... electronics as well and there's also physical chemistry, you might not like it or at least see it clearly but it's because it's in everything around you...

As important as the experiment they perform.\n\nUntil then, they are just materials for an experiment.

For everyday general physics we can rely fully on maths.as basic problems solved are already established by experiments.for example in general gravitation,electrostatics,magnetics.maths used in these areas is also confirmed by a great extent to s.\n \nBUT we don't establish a physical fact by mathematical calculation only.it is established only after theoretical proof.for ex till date we call theory of relativity only "THEORY" while it is established by both logical and mathematical proofs.there are some experimental evidences also but they are not strong enough to establish this theory beyond question.\n     \n \nso basically physics don't rely on math but math is used only as a tool for our logical findings of physics whenever and wherever required.

Yes, or at least they should if you put some effort into the subject.  Even if the subject matter itself never appears on the exam, physics forces you to look at things in a very analytical sort of way.  The basics skills developed in a proper physics course will help across the board whenever you are called upon to qualitatively look at something.

What is required for definite measurement for any volume is a sense of boundary. Therefore, we could estimate the volume of the universe, but we aren't sure.  Therefore it's pure speculation.\n\nIn terms of liquids, they do have a defined boundary by the changes of the index of refaction from when light enters the liquid.  Therefore, with a predefined container that has calibrated unit of measurement, one can easily determine the volume of liquid for a given temperature and pressure.  Remember, liquids can expand and contract due to changes of pressure and temperature, although the changes in volume do not change sinificantly.\n\nOn the other hand, a gas that is lighter than air would be very difficult to maintain within a system to measure directly.  Given a closed container, with a definite pressure and temperature, you could estimate the amount of volume that the gas should fill.  Rememeber, since it's lighter than air, the mass would be difficult to measure, unless you had a airflow meter to measure gas flow by mass.  The result should be the same for every repeated condition, a certain amount of mass should fill the vessel to a specific pressure at the given temperature.  On the other hand, gases that are heavier than air should be more easier to measure their volume; this case can only be applied to gases that has a define boundary due to color.  Therefore, at a specific temperature and pressure, you could estimate their volume and measure their mass.\n\nIn measuring gases, usually volume is correlated to temperature and pressure.  Usually, the best thing to define about any liquid or substance is the density at a given temperature and pressure.  This will undoubtedly define the physical property of the object at those conditions.

It depends on what substance you're talking about as well as many other factors. In Quantum Mechanics, the observation of particles affects the observers ability to measure certain properties. For example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. It's like trying to find out where a grain of sand is by throwing other grains of sand at it. Once you find out where it is, it's been moved. It's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. Paradoxically, the only way to find out is to be there and hear it.

Planck's Constant is a central feature of quantum mechanics, and the study of quantum mechanics has led to such practical applications as laser technology,transistor technology,the electron microscope, magnetic resonance imaging (diagnostic medicine), and countless applications in chemistry research.

This is a provocative question...Thank you!\n\nFirst off, Science IS...It is simply a measuring stick for this universe that we find ourselves in...and how to intelligently explain it...Is not an either/or question!\n\nAnd, there is nothing that cannot be measured, or explained!

Look around yourselves almost everything around you has some physics.The computer you use ,the vehicle you drive ,houses we live in ,various appliances we use everything has some physics involved.We are in effect trying to study the very nature of things there physical properties .

it's important in engineering work such as calculating how high objects move or what's their max speed.

Studying Physics involves a great deal of thinking. Just by doing questions from textbooks or those set by teachers and lectures are not enough. \n\nTheories and concepts in Classical Physics can usually be understood by using common sense. However, common sense doesn't work for modern Phyiscs or Quantum Phyiscs.
