Why does physics rely heavily on math? How can we be sure that this is all true?

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.

Algebra and all the Maths that one learns at school and college are tools which are ultimately used by Scientists, engineers, doctors, and almost all the people who have something to do with science. Even social scientists like historians and sociologists use it. \n\nIt may seem abstract but Maths is the underlying machinery of the Universe.

i love Physics, but not either of them are that easier, u see!\n so do as ur heart says to do!

The most important thing is to convince yourself that all what is mathematics has an explanation, so you are SURELY able to understand it.\nIf you need more time, take your time, but never loose confidence in yourself, and try until you succeed in doing it.

In a strict sense, science is a branch of philosophy.  Where science differs is in what is called the scientific method, which basically says that a hypothesis must be testable and the results reproducible. A good hypothesis also makes predictions that can be tested as well. To answer your question, string theory tries answer the question of what matter and energy are and how they relate to one another at their core. Quantum mechanics does a good job answering part of the question but breaks down when gravity is considered.  Einsteins relativity also answers some questions but it too is unable to adequately explain gravity with concern to the other elementary forces.  String theory attempts to bring these two well tested theories, Quantum theory and Relativity together into one Grand theory.  It uses complex mathematics that are not easily understood but because the energy requirements that we would need to test this theory are currently and probably forever out of our reach it can't be tested. If it can't be tested it is not in the strict sense science but philosophy.

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...

You need LCM to do the merest math, which is needed in all the sciences. You cannot do chemistry, biology, physics, geology, astronomy, meteorology, or any science without knowing LCM.

mathematics is a bais of other sciences . without mathematics we will not underestand physics. both physics and mathematics are basis of technology.

yeah surely you can , but ... just you must try hard , not spending all the time in the internet , just go and spend your time on physics !

I am pretty sure that if you looked in your textbook, it would give examples of this kind of thing, and from that you should be able to figure it out on your own. You're a smart kid, you are taking physics instead of some easy A class, now act like it, stop asking others to do your work, and try to solve it on your own.\n\n\nLong Live Jambi

improving in physics or math doesn't only rely on good books, you also have to work really diligently and discipline yourself. to solve a problem efficiently, list out the given informations. then, write all the formulas you can think of that applies to the problem, and evaluate which equations are most applicable to the situation. to really improve, i suggest that you do the exercises in whatever book you might have. (i recommend conceptual physics by hewitt, since it's easy to understand), and actually answer at least 40% of all the problems for a particluar chapter. if you got a wrong answer, always analyze what went wrong in your euations, so you won't make the same mistake. read, read, read. also, it's helpful to understand the basic concepts which underly the equations you use. don't try to do the challenging stuff first, until you master the simpler ones, and until you really understand the theory behind the math. it's tough work, but you can really improve if you try hard.

I figure that a theory that predicts 6-7 extra dimentions may be true, but it is really easy to explain things with 9-10 degrees of freedom..\n\nTHink about it, you have data... you try to make a linear fit, most often you don't get a good correlation... Now try a 4th power polynomial fit... you get something better... 11th power can describe any data, but it makes no really valid predictions. \n\nAs Einstein said, "Any fool can make things bigger and more complicated" (don't remember exact words so this is paraphrasing) "but to explain things in simple manner truly takes a genius"\n\nBut there are things about it that are likely true, for instance the "strings" themselves... Yes, everything is made of a fundamental unit of energy (double slit experiment demonstrated that matter is localized energy) \n\nLast point: to have a valid theory it should predict measurable results, string theory does not.\n\nSo no, I doubt its tue, but only time will tell.

Math is used all the time in the engineering sciences.  Many physical phenomena, including fluid flow, heat transport, and diffusion can be described by appropriate partial differential equations.  In order to solve these equations and make predictions, you need to be good at calculus.\n\nIf you limit yourself to addition, subtraction, multiplication, and division, you would be stuck with linear models for everything.  This means that any more complicated relationship between two variables could not be modeled continuously, and you would never be able to extrapolate with any confidence.  Thus development of new technology would be strictly trial and error (and you wouldn't even have a good trial and error system without statistics).\n\nHang in there!  Get through that math.  You don't have to like it, but you will inevitably appreciate the developments that math has enabled.

We're just doing this in a mixture of psychology and advanced mathamatics. Yea, what's needed is scientific tests to find out, to the most exact extent, what is safe. There's groups will do all of that for you, alternatively just go to college and learn all this stuff. Or if it doesn't matter too much [say no one could ever be hurt] then just give it a good try your self.

It is a science. Trying to understand how things works, through observation and logical analysis. It is less precise or clear-cut than physics or chemistry, but that's because the subject matter keeps changing.

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.

Math is needed for lots of things!\nDo your homework!\n\nhttp://mathforum.org/dr.math/faq/faq.why.math.html\nThere are actually thousands of different jobs that require some knowledge of mathematics. Here are more than 30 firsthand accounts from Mathematicians at Work telling what some college math majors are doing, from an Air Traffic Control Systems Analyst and a Lawyer to a Data Capture Facility Troubleshooter on the Hubble space telescope.\n\nExactly How Is Math Used In Technology?, from the Mathematics Department of the British Columbia Institute of Technology, provides examples of math uses for biomedical engineering, food technology, building technology, chemical sciences, civil and structural engineering, graphics and computer-aided drawing (CAD), electronics, environmental health, mechanical engineering, mining technology, nuclear medicine, occupational health, petroleum technology, prosthetics, forestry and wildlife, robotics, and surveying.
