Newton's Calculus: Numerical Methods or a New Math?

In summary, the conversation explores the relationship between mathematics and physics, considering whether math is primarily a tool for solving problems in physics or if it can still make significant progress on its own. Some argue that physics drives new mathematical developments, while others point to examples where physicists have made significant contributions to mathematics. There is also discussion about the distinction between applied and pure mathematics and whether it is ultimately relevant.

When Newton wanted math to express his physics he invented calculus (i'm not trying to be totally historically correct - this isn't my main point). It seems like today we're in a similar position - there're lots of things that simply can't be exactly solved. are numerical methods the next step? or is there a chance that someday we'll come up with a new kind of math that can let us solve problems that are insolvable today?

Well, that is kind of the point of science. Remember http://www.foxnews.com/story/0,2933,209757,00.html?

Could physics be said to be the main driving force to new mathematical developments?
 
  • #4
Since mathematics can be said to be a tool for problem solving in physics and science in general, sure, why not.

Because most of the last 100 years of mathematics has developed without any impetus from physics, perhaps? Indeed, some of the more fashionable areas of physics are learning from maths, and not vice versa.

I doubt you will find any mathematician who agrees with this statement!

Prob and stats has kinda been 'invented' (or developed a lot) over the last century and a bit.

I don't see where math can still make significant progress... then again I would have said the same thing if I lived 300 years ago, so who knows.

I would think that when there are still many unsolved problems, and undoubtedly many others yet to be discovered, that there are plenty of places that allow for significant progress in mathematics.

Rofl this reminds me of a hilarious teacher i have, on his homework sheets he has :If gifted students are not feeling challenged enough, try proving/disproving the countability of the real numbers, or one perhaps the Riemann hypothesis" Nice

O yes let me just say I am not 100% sure, but the last time a physicist "invented" math for physics solely, was back in 1923 with Werner Heisenbergs Matrix mechanics. Sadly, he didnt know matrices were already invented >.< Since then, any physics calling for mathematics has been either satisfied by known methods, or merely extended in ways that a mathematician would have had no interest for anyway, and if they did they would have bothered to.

maths may advance in depth rather than in extension

Well... there are some recent cases of physicists certainly significantly augmenting certain topics of mathematics, if not quite inventing whole new "paradigms."

I'm thinking of Penrose's twistor theory, which began in the late 60's, as an attempt to start unifying QT and GR, but was soon grabbed hold by many geometers as a way to help understand 4-dimensional manifolds.

Similarly, I believe that Witten both helped develop the Seiberg-Witten equations (another method to grapple with 4-manifolds) and accidentally reinvented K-Theory for purely physics-related reasons.

Plus, spin networks from quantum theory have helped guide the progress of some areas of discrete geometry. And string theory has certainly put certain very abstruse mathematical ideas back on the collective map.

Granted, though, most of the above work seems to originate from the mathematical physics end of things *and* none of them have as yet had the same paradigmatic impact that Newton's and Leibniz's calculi had.

Are penrose and witten really physicists though? In the words of McKay (roughly) the distinction between applied and pure is a sham.

Well, that's not really my call, since I am a mathematician. If you don't want them in your camp, we'll take 'em. :smile:
 
  • #16
And what makes you think I'm not a mathematician (follow the link in my signature to my homepage)?
 
  • #17
matt grimes a mathematician btw Doodle.

I would say the are physicists, and they say it themselves. It is because, in their view, the use their "tool" of mathematics for the sole purpose of explaining physical phenomenon. In their view, if they advance their tools they can advance their work. A pure mathematician does it purely for the beauty of the mathematics. If it has an application, good for the physicists, but the pure mathematician won't give a damn.

O sorry I didn't read matts last post, it was on the 2nd page >.< well yea, now you know he's a mathematician.
 

1. What is Newton's Calculus: Numerical Methods or a New Math?

Newton's Calculus, also known as Numerical Methods or a New Math, is a mathematical method developed by Sir Isaac Newton in the 17th century. It involves using infinitesimal calculus to solve problems and make predictions in various fields of science and engineering.

2. How is Newton's Calculus different from traditional calculus?

Newton's Calculus differs from traditional calculus in that it focuses on the use of numerical methods and approximation techniques to solve problems, rather than the more analytical approach of traditional calculus. It also places a greater emphasis on the practical applications of calculus in various fields.

3. What are some real-world applications of Newton's Calculus?

Newton's Calculus has many real-world applications, including predicting the motion of objects, calculating the rate of change in natural phenomena, and solving optimization problems in engineering and economics. It is also used in various areas of physics, such as mechanics, thermodynamics, and electromagnetism.

4. What are some limitations of Newton's Calculus?

One of the main limitations of Newton's Calculus is that it is based on the concept of infinitesimals, which are very small numbers that approach zero but are not actually zero. This can lead to inaccuracies and errors in calculations. Additionally, it can be difficult to apply Newton's Calculus to complex problems and systems with multiple variables.

5. How is Newton's Calculus relevant in modern science and technology?

Newton's Calculus continues to be highly relevant in modern science and technology. Its concepts and techniques are used in fields such as physics, engineering, computer science, and economics. Many modern advancements, such as the development of the internet and space travel, would not have been possible without the use of Newton's Calculus.
