Physics: applied Math. Math: dressed up Logic (Gödel, hush). The natural conclusion, of course…
Without light, darkness cannot exist.
Without physics, math holds no meaning, without math, physics cannot be sensical. Both are equally needed and important. (Also, only haters ask that kind of question. So stop drinking haterade and stop hatin’.)
“Physics is to math as sex is to masturbation.” -Feynman. (What a badass.)
“physics is a golden ball… if you want to take it… you should take a ladder called mathematics”
mathematics is the father of all subjects
Math is better than Physics because in physics math is used.There can not be Physics Without Math.
To proof any theorem of physics,math is must..nothing can be proved without math..but one of my fiends says that the thought of adding two no. is physics and the process is done by math.So physics is first.
Say it’s a dark night in winter and you need to do some mathematics and its pitch black so you go to turn on a light but oh no the light because nobody ever used physics to create a lightbulb
math of course,Physics without math is nothing1
This is an easy question to answer, mathematics is more abstract and less practical. Physics is necessary and utilized in every facet of modern technology, mathematicians are more concerned with manipulating numbers than implementing numbers and constructing systems (other than statisticians.)
I am convinced mathematics and physics are codependent upon one another in many regards. However, I think a person can be good at math and not physics, while a person can be good at “physics” and not math. There have been physicists who could observe nature and understand how systems work WITHOUT mathematics. There are also mathematicians who are excellent at abstract proofs, while being terrible at applying their knowledge.
