Talk:Timeline of mathematics

message: An amazing feat, if true:
* 1955 -  Enrico Fermi, John Pasta, and Stanislaw Ulam numerically study a nonlinear spring model of heat conduction and discover solitary wave type behavior,
Fermi died in 1954.  Perhaps someone with mroe knowledge of the detail can change this (perhaps the PUBLISHED in this year). A little pedantic, maybe, but. . . John (Jwy) 23:24, 20 February 2006 (UTC)

message: There is no name of grothendieck and hence the list is not serious. moreover, as far as i know there is no real arab mathematician at all, all notable ones are persian but writing in arabic. the list has to be removed completely.
Indeed it is not serious not to mention the greatest mathematician alive (could be disputed).
However see Timeline of category theory and related mathematics and choose your pick of Grothendieck.
In my oppinion almost everything in modern mathematics is missing, not only category theory, but also for instance analysis.
But the blame can not be put wholely on the creator of the timeline but on all who could include these things but don't.
In fact mathematics is developing exponentially so the majority of entries should be in the past 100 years, sadly they are not.
Yes, i have some entries to include, but i don't have the time.

thread_title:  non-sense list. 

message: I am a casual visitor. Some of the dates given in the timeline are impressive, but they looks like pushed centuries back in time. This is especially the case of a part of Indian mathematics. Many dates are contradicted by other Wikipedia articles and common sense. 
I cancel the following "1500s - Jesuit missionaries in India translate many astronomical and mathematical Indian texts and transmit them to Europe" Do not restore it unless you can give a single one title of such translated text.
I move the text about Babylonian abacus from 2400 BC to 300 BC (see abacus, Wikipedia). 
I do not change the following.
"ca. 2800 BC - Indus Valley Civilization (...) the smallest unit of measurement used is 1.704 millimetres and (...)." One may trace this back to an artefact unearthed in Lothal, but Lothal did not exist in 2800 BC yet. By the way, I am curious, how did they define the unit up to one micrometer. With a microscope?
"2600 BCE - Indus Valley Civilization - objects, streets, pavements, houses, and multi-storied buildings are constructed at perfect right angles, with each brick having the same dimensions". Well, true. But regular bricks were known e.q. in Catal Hoyuk in Anatolia 3300 years earlier, streets, pavements, houses were rectangular also 3000 or 4000 years earlier elsewhere (Jarmo, Tell Buqras etc.), multistoried buildings too. Indus Valley Civilization was not the first to discover right angle.
2800 BC - The Lo Shu Square (...) was discovered in China." One may trace this to the statement in Wikipedia that it is found in Chinese literature text from 2800 BC, but there were no Chinese literature at that time (and even 2000 years later). 
"ca. 1800 BC - Vedic India - Yajnavalkya writes the Shatapatha Brahmana, in which he describes (...)." Tell me, what writing system was in use in India 1800 BC? Maybe it was written 1500 years later?
"600 BC - Apastamba, author of the Apastamba Sulba Sutra (...)". Wikipedia says he lived some centuries later.
And so on, and so on.

message: I just added GRR, und Eilenberg-MacLane, Eilenberg-Steenrod-axioms
As someone before pointed out regardless on which side of the co-homology-gap one is, not mentioning Grothendieck and Catheories is pathetic
but the list still remains woefully incomplete...
on the other Hand a lot of stuff is contained that might not have a place in a timeline of general mathematics.
Results in my opinion should be:
- Major Conjectures which drive programs (Hilbert-Program, Weil Conjetures, Milnor Conjecture, Moonshine (or whoever it is called the one about vertex(?)-chiral-algebras which Borcherds proofed, the Langelands proofs, Bloch-Kato, Beilinson-conjectures, the Swinerton-Dyer Conjecture (sry spelling?!)
- Really Major Theorems: GRR (Grothedieck-Riemann-Roch), The Atiyah-Singer-Index Theorem, Fast Fourier Transform and the like
- Foundations of new Programs: Grothendieck-Remake/GAGA, NCG, Mori-Program, Game-Theory, Probability, Quillen K-theory
- Second Proofs only it they bring something new about: e.g. Gowers new proof of Szemerédi's theorem
Maybe a good strategy for deciding what to mention whould also be to take only theorems which have an entry in the Princeton Companion on Mathematics (unfortunatly I don't have a copy ready)
I also very much think that the date for Noncommutativ geometry is just just plain wrong:
It might be sensible to mark the starting of NCG (or at least the Connes style variant) with the following article
Alain Connes, Noncommutative differential geometry, Inst. Hautes Études Sci. Publ. Math.
(1985), no. 62, 257–360.
I will try to think about a better date the next days
The date in the article seams to refer to 
the Lott-Connes paper: "The Metric Aspect of Noncommutative Geometry",
in New Symmetry Principles in Quantum Field Theory (Carg�ese, 1991), NATO Adv. Sci. Inst. Ser. B
Phys. 295, Plenum, NY, p. 53-93 (1992)
17. \Superconnections and Higher Index Theory", Geom. Funct. Anal
While this might be a fine paper calling this "developing" noncommutativ geometry is just preposterous.
If no one objects I will remove this entry and give a more appropriate date for the introduction of NCG (the NCDG-paper is still not optimal for a variety of reasons but the best I could come up by now)
There are also a Variety of other things that ought to be mentioned in a serious timeline, I will make suggestions in the next days
A good general guideline might be that at least Fields medal winning results should be mentioned somehow because they had a major influence on mathematics, on top of head at elast the following ought to be inculded- :
Roth's theorem on arithmetic progressions (after all there is Tao-Green is mentioned)
Resolution of Singularities 
- Stefan Banach's work on Banachspaces
- The Weil-Conjectures
- The three Proofs of the Weil-Conjectures (or at least Deligne's)
- Poincares Analysis Situs (after all this was the birth of modern topology)
- Grothendieck's remake of the foundations of AG in the 60's
- Serre's GAGA
- Algebraic- K-Theory
- Selberg Trace Formula
- Milnors Exotic Sphere (because it disproves the Hauptvermutung)
- Simon Kiriwan Donaldsons- Donaldson Conjectures
- The  lower dimensional Topology Thurston did
I also think some mathematical Physics ought to be included:
- The Kolmogorov-Arnold-Moser Theorem
- Yang-Miles-Theory and the things Sir Atiyah did, relating to this
- Chiral Algebras
- TQFT
- Mirror-Symmetry
... (and more but I can't think of anything right now)
In general conjetures which drive large developments in a given field should be included: i.e. Die Hauptvermutung, Milnor-Conjecture, Bloch-Kato
Given the shameful state of the list as it is I think some entries ought to be removed, because they are not important enough to be included in a general timeline of mathematics. 
A lot of stuff of arguably lesser importance should be removed:
-1912 – Josip Plemelj publishes simplified proof for the Fermat's Last Theorem for exponent n = 5, (this should be removed- not important enough)
-1913 – Srinivasa Aaiyangar Ramanujan sends a long list of complex theorems without proofs to G. H. Hardy,
-1914 – Srinivasa Aaiyangar Ramanujan publishes Modular Equations and Approximations to π,
-1910s – Srinivasa Aaiyangar Ramanujan develops over 3000 theorems, including properties of highly composite numbers, the partition function and its asymptotics, and mock theta functions. He also makes major breakthroughs and discoveries in the areas of gamma functions, modular forms, divergent series, hypergeometric series and prime number theory
should be unified into one entry
-1933 – Karol Borsuk and Stanislaw Ulam present the Borsuk-Ulam antipodal-point theorem,
should in my opinion be removed ( I din't know the result,and it certainly does not look like an earth shatering result
-1943 – Kenneth Levenberg proposes a method for nonlinear least squares fitting,
I don't know the result is it significant enough to show up on a timeline of general mathematics? (I don't know of either autor or result please enlighten me)
-1961 – Daniel Shanks and John Wrench compute π to 100,000 decimal places using an inverse-tangent identity and an IBM-7090 computer,
I think this should be removed, this was neighter the first nor the best computation of π on a computer. JvN's ENIAC compuation is already mentioned
1987 – Yasumasa Kanada, David Bailey, Jonathan Borwein, and Peter Borwein use iterative modular equation approximations to elliptic integrals and a NEC SX-2 supercomputer to compute π to 134 million decimal places,
1991 – Alain Connes and John W. Lott develop non-commutative geometry,
See above
I am not sure about the following
-1956 – Noam Chomsky describes an hierarchy of formal languages, (this was a recent edit if you check the history, in how far is it relevant to mathematics?)
-1965 – Iranian mathematician Lotfi Asker Zadeh founded fuzzy set theory as an extension of the classical notion of set and he founded the field of Fuzzy Mathematics,
-1973 – Lotfi Zadeh founded the field of fuzzy logic,
-1919 – Viggo Brun defines Brun's constant B2 for twin primes,
I am not sure how relevant this is?!
I think in the 
1998 – Thomas Callister Hales (almost certainly) proves the Kepler conjecture, entry "(almost certainly)" should be removed.  — Preceding unsigned comment added by 82.82.69.128 (talk) 09:57, 29 July 2011 (UTC)

message: I check pages listed in :Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles.

I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.
