# Why physics and not maths

Hi,
it just so happened that it took me few weeks to finally write something. I was over the holidays on Mallorca and then I missed the last week too, oh well, today I will compare some aspects of physics and maths that I noticed and why I choose physics over math.

This is something I have realized lately during solving of physics and math problems. While math is certainly groundstone of physics the thing I dislike about math is its formalness and its need to be exact, actually, I guess the need is there because of its possibility, in the real world, not only that it is just too hard or impossible to model some situations but it is also worthless to know the answer for any number of decimal places[1]. What I really like about physics is how you can approach a problem and tell yourself:

“I can neglect this part because it won’t change the situation much.”
“I can approximate y=sin(x) close to 0 as y=x because it gives me similar values.”
“Let’s use this numerical solution for this difficult integral.”

Yeah, I love how in the real world you can approximate, though at the same time you have to keep the balance so that the solution is still useful. Math is too exact for me. I do like proofs but it has to be with balance and I need to be able to see in the world around me what I learned.

I will keep it short and end it with this meme:
