Of course, he is much more famous as a fiction writer than as a mathematician and it can be easily argued that much more important mathematicians (e.g. Grassmann & Clifford and many others) are missing from that timeline, but he certainly cannot be considered as a non-mathematician.
(Also, Yau is there.)
They added Katherine Johnson who developed no new theories or applications on Math or Computer Science, but left Margaret Hamilton out (and she was the pioneer and creator of an entire new field!)
Always bothers me the same happens in Civilization games with scientist lists.
I guess I just have an inclusionist mindset with these matters. Popularizers, esotericists, eccentrics, early pioneers of new thought-tech, and people in closely associated fields should at least be considered in projects like this. Contributing to mathematics culture seems important to me, not just contributing to mathematics achievements.
Citation needed. You might be able to argue that it had its beginning in EE departments, but CS as a field did not spring from math at all. Seriously there is a difference between formalizing something in mathematical language - which happens to almost every technical field - and having that formalization be considered an advancement in math itself. This is exactly my point about throwing everyone "technical" into the mix. After all, the formalization of chemistry requires lots of math, so Marie Curie must be on the list of mathematicians, too!
By whom? Obviously the poster did. Lots of people think of him in connection with his work in logic, which isn't research-level, but I think of him in the context of, e.g., https://en.wikipedia.org/wiki/Dodgson_condensation , which to my somewhat amateurish knowledge of the subject was a research-level contribution for its time.
So what? The site is a Timeline of Mathematics, not a Timeline of Mathematical Research. Surely notable new applications of mathematics belong on the timeline, regardless of whether they involved new research or not.
Could you provide a source on this? DDG only shows youtube videos and conspiracy websites when searching.
Minor correction but the discrete wavelet transform based on Daubechies' work is used in JPEG2000, not JPEG, which uses the discrete cosine transform (other codecs generally use related integer approximations). JPEG2000 never managed to gain much popularity outside of digital cinema (e.g. Red RAW, Cineform, and I believe delivery codecs for cinemas). Which is a shame, given that wavelets have superior properties for multi-resolution decomposition.
JPEG has the big advantages that it is built in to web browsers, can be decoded effectively on less powerful hardware, and is “good enough” for most typical uses.
> Al-Khwarizmi also worked in astronomy and geography, and the word “algorithm” is named after him.
Pretty design for what it does, though!
The width of 100 years looks like it might be different each century.
I also appreciate how they aren't really connected to each other to suggest a linear timeline of events. Nobody had infinite comprehension of all historical knowledge and simply hoisted themselves upon the shoulders of everything that came before.
Reality is super messy. Almost as messy as a jumble of people on a screen

Actually Wikipedia has a list of Indian Mathematician from which I see many names are not in this page 
Newton — Euler — Gauss — Poincaré — Turing — Yau
An old C. F. Gauss could have met baby Henri Poincaré, yet
in my mind they live in completely different universes.
Having started on the project for about a month now, I have an appreciation for the amount of care that has gone into that the mathigon site.
Kudos to them for providing such a high quality free resource for building passion and education in maths.
In relation to people commenting that some names are missing and some are not specifically mathematicians etc. It doesn't matter - the project is ongoing, the learning resources have plenty that are still in construction - and any name mentioned sits somewhere in the realm of math interest.
It is a great site. Very polished.
Then the banks (and so some Italians) arrived and it all got more relevant.
Selling the Bernoulli clan a bit short here.
This all looks very pretty and it's likely useful for teaching but it begs the question of how good the input data is. The old adage about garbage in, garbage out is true no matter the source.
I wish they would add some of the arab mathematicians
algebra is an arabic word
Unfortunately I quickly got to some "COMING SOON" sections
Notably the explosion of math in Europe from the 1500s.
I wonder if the printing revolution had something to do with this.
