What is Mathematical: Definition and 1000 Discussions
Mathematics (from Greek: μάθημα, máthēma, 'knowledge, study, learning') includes the study of such topics as quantity (number theory), structure (algebra), space (geometry), and change (analysis). It has no generally accepted definition.Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof. When mathematical structures are good models of real phenomena, mathematical reasoning can be used to provide insight or predictions about nature. Through the use of abstraction and logic, mathematics developed from counting, calculation, measurement, and the systematic study of the shapes and motions of physical objects. Practical mathematics has been a human activity from as far back as written records exist. The research required to solve mathematical problems can take years or even centuries of sustained inquiry.
Rigorous arguments first appeared in Greek mathematics, most notably in Euclid's Elements. Since the pioneering work of Giuseppe Peano (1858–1932), David Hilbert (1862–1943), and others on axiomatic systems in the late 19th century, it has become customary to view mathematical research as establishing truth by rigorous deduction from appropriately chosen axioms and definitions. Mathematics developed at a relatively slow pace until the Renaissance, when mathematical innovations interacting with new scientific discoveries led to a rapid increase in the rate of mathematical discovery that has continued to the present day.Mathematics is essential in many fields, including natural science, engineering, medicine, finance, and the social sciences. Applied mathematics has led to entirely new mathematical disciplines, such as statistics and game theory. Mathematicians engage in pure mathematics (mathematics for its own sake) without having any application in mind, but practical applications for what began as pure mathematics are often discovered later.
I am a high school senior now and I would love to pursue a career in math.

I understand what research might be for life sciences or social...

Mathematical uses of the preposition "of"
Dear Professors,
I am looking for any articles on the uses of the preposition "of" in mathematics. I once read in a teacher's edition of a pre-algebra textbook that suggested students should be taught, as early as possible, the many uses of the...

Some people call it physics that simply is more difficult or reliant on mathematics. I was wondering if anyone could enlighten me a bit more as to what types of maths and physics areas are generally equated with mathematical physics.
Hi all, I have a question. I'm hoping to be a theoretical physicist, but I'm finding I really don't know the first thing about mathematics. I can plug and chug with the best of them, and I have a feel for various integration techniques, and I know enough tricks to get by (Fourier series, Fourier...
I think there are only two primary languages, i.e. natural language and mathematical one, which we use to communicate . If we go one step further, then I would say even mathematics is a subset of natural language where we use symbols and other signs to represent our concepts, ideas into...
mathematical explanation of maximum speed limit "c'
i have tried many texts and searched but can't find particular mathematical proof or explanation of how sp.theory led to conclusion that maximum velocity limit is "c"
I realize this might be a little bit of academic advisement, but I think it'd be more useful to have some people who really know a lot about the subject post about this. I like math a lot, and specifically I was wondering about number theory or set theory and logic, which is interesting but I'm...
Are we made of pure mathematics? Is everything in universe mathematics?
I mean, everything in physics is "written" in math.

What is this class like? Is it very hard? I took an intermediate macroeconomic theory course a couple of semesters ago. One of the prerequisites for this class is Probability. I will be taking that next semester. I wonder if I could take these two classes concurrently.
(3*e^(-2s))/(s(s+5))
I was hoping someone could tell me how to find the partial fraction for the above; the answer i ended up with was: (3/5)/s - (3*e^(10))/(s+5) and i went about it by:
(3*e^(-2s))/(s(s+5))=A/s+B/(s+5)
(3*e^(-2s))=A(s+5) + B(s)
set s=-5 and found B=-3*e^(10)/5
