# What are the real-world applications of real analysis?

I've read the wikipedia article on mathematical analysis and this, but I can't exactly find an answer. Is real analysis just some pure math, or does it really have something to with physical applications? Feel free to send me any references that might answer my question, thanks!

• Any way I can somewhat refine my question? – joejacobz May 5 '13 at 14:59
• The name "real analysis" has not anything to do with "real applications". It hints that we're doing analysis using the real numbers. – Fredrik Meyer May 5 '13 at 15:37
• Can you be a bit more specific about the definition of 'real analysis' and 'real world'? – Alex May 5 '13 at 16:22

• +1. "Analysis was invented to understand the circumstances under which these methods produce correct answers". $<=$ Quite true !!!. – Felix Marin Jun 15 '17 at 19:37
