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.
"Mathematics is the gate and key to the sciences", Robert Bacon said. That statement is as relevant today as it was 800 years ago. Human culture changes but mathematics is forever. Mathematical beauty will be as relevant to mathematicians and poets today as it was thousands of years ago. Surely...
I plan to study from Peskin and Schroeders book if it helps, I just need to know what topics I need to study and it would be greatly appreciated if someone could tell me what books are good on the subject, I have a limited budget however and if I could get a single or only 2 or 3 books covering...
Do you think that matter, energy, space, time, etc. are discrete, or continuous?
If they are discrete, is continuous mathematics limited to a very, very good approximation for modeling physical phenomena?
Hello all,
A brief history is that as a child (I'm only 26 now) I had performed poorly at Mathematics and it wrecked my confidence. I had no interest in long division, basic algebra etc and focused elsewhere because I never viewed it as a means to an end. Suffice to say I suffered a bit of Math...
Just like calculus (single as well as multi-variable) and linear algebra are not only useful but really similar to classical mechanics. What are the branches of mathematics that I need to know in order to have that same feeling of deja-vu when studying electricity/magnetism and waves/optics? I...
Hello everyone!
As the title of this thread possibly suggests to you, I'm not very skilled with mathematics. I would like to say I don't blame my teachers, I'm not insinuating that by any means. What I'm hoping to find is a book that can teach me "from the ground up" (the basics to calculus...

Hey guys, the title basically says it all! I'm looking for a book to work along side Serge Lang's basic Math's book. Something which goes into topics more in depth. I'm out of scratch with my Math's :(
Hope someone can point me to a good text!

How do you think of numbers when you're doing math? I particularly feel like sometimes we get to close to acting like computers. We just scan through a list of symbols and compute another list of symbols that makes sense in a certain context. We hardly ever think of things concretely and how...
