AI Thread Summary
A user is seeking a specific quote related to expressing understanding numerically, believed to be from Newton or Kelvin. Another participant suggests a quote from Galileo about mathematics being the language of science, which is appreciated but not the sought-after quote. The discussion includes various mathematical quotes, such as one attributed to von Neumann and another often linked to Einstein about the nature of counting. The original poster remains uncertain about the quote's existence but continues to search for it. The conversation highlights the significance of mathematical language in science and the challenge of pinpointing specific quotes.

Hello all,

I've been looking for a quote that I heard a while back that I want to use, I've searched as much as possible but I'm unable to find it!

The quote is along the lines of 'to fully understand something one must be able to express it numerically', i was certain it was a quote from either Newton or Kelvin but have had no luck finding the exact quote.

A link to, or the quote itself would be really appreciated.

thanks

Nick

p.s. sorry if this is in the wrongs section, couldn't decide were to put it.

Hello Nick! Welcome to PF! :smile:

Are you thinking of Galileo's quote? …

Science is written in this greatest book (I mean this whole universe) which stays open for us ceaselessly before our eyes: but no-one can understand it if he does not first learn to understand the language and the letters in which it is written.
The book is written in the language of mathematics, whose letters are triangles, circles, and other geometric figures, and he who does not understand these letters is helpless to truly understand a single word that he sees.​

Hey Tiny-tim

Nice quote, haven't seen that one before

my fave saying, i don't know if it has a specific origin tho...
simply...

Mathematics is the language of science

cheers

Hi Tiny Tim, thanks for the reply. Although that is a great quote it wasn't the one I'm thinking of. I've trawled through google but can't find it, starting to wonder if I've just made it up... but then again it was a really good quote so I doubt it!

I'll keep on having a look and report back if I find it.

Thanks for your help

Nick
 
"With four parameters I can fit an elephant, and with five I can make him wiggle his trunk."
- Attributed to von Neumann by Enrico Fermi, as quoted by Freeman Dyson in "A meeting with Enrico Fermi" in Nature 427 (22 January 2004) p. 297

I use it to annoy my friend who is writing a model for neutron stars with 4 free parameters.
 
"Not everything that counts can be counted, and not everything that can be counted counts."

This quote is usually attributed to Einstein, but it's also attributed to a sign on the wall of Einstein's office. Sort of an appropriate twist to the story of this quote.

Alas, the probability that this was the quote you had in mind may not be particularly high. :frown:

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
