It's a bit low on my priority list, but I'm working on that!

Oh wow! I wouldn't have expected this so many years later. Mordel's conjecture implies asva special case that for all n>=4 there are only a finite number of solutions to Fermat's equations with relative prime numbers. Brings me back!

> Mordel's conjecture implies as a special case that for all n>=4 there are only a finite number of solutions to Fermat's equations with relative prime numbers

I just learnt that fact from Wikipedia's article on Mordel's conjecture (now Faltings' theorem), was curious whether the theorem could be strengthened to obtain a full proof of Fermat’s Last Theorem (FLT) that is genuinely different from the Taylor–Wiles proof (or its later variants) and so asked an AI (in this case Grok via Twitter).

Grok correctly told me "no it's not possible", but then surfaced (as an aside) a nice expository article on the Taylor–Wiles proof by Faltings from AMS notices in July 1995, which I thought I'd share here:

Interesting! I am building a spreadsheet and the next few months will be building the collaborative side of it. I think many of the things that work for text don't necessarily translate for spreadsheets.

We made a spreadsheet on top of OT several years ago. Most OT related documentation doesn't talk about how to do this. But it worked pretty well for us.

Well, I just jumped full time on IronCalc[1] a fully open source, light and fast spreadsheet engine designed and build from the ground up.

I have been working on it as side project for over two years and now, with funding from the EU for the next 2.5 years, I hope I can make of it a real product for everyone to use that can compete with the likes of Excel and Googl;e Sheets.

I can oly say, I am overly, off the Moon excited

Which EU grant did you receive? Ie. from which fund?

edit: nm, rtfm, it was on the landing page: Horizon Europe programme


Answered to a sibling comment. NLnet and HORIZON.

NLnet is just amazing and can keep you going if you are a student or have some extra sources of income

HORIZON is a huge grant but fairly hard to obtain. Generally related to reasearch grants in academia


Looking at it and very excited. In unsupported features, charting is mentioned. Could there be any value in not directly implementing the drawing of charts, but tie in to other open source library? Just curious of your thinking.


I think charts is one of those few things I won't implement from scratch, as there are already fantastic libraries out there:

We will start working on it by July according to the plan. (This will add a lot if value to the project BTW)


Oh, neat. Didn't expect to see IronCalc here for some reason, have been considering it for a side-project. Thanks for the hard work. :)


Interesting, how was the EU funding process?


First we got a grant from the NLnet[1], which I highly recommend as a first step of any project. Single best thing I could have done. That wasn't enough money for me to quit my job. Also I didn't have any _evidence_ that IronCalc was a good idea or that there was a market for it. Then evidence started pouring and I kept working. I started talking to different folks, lots of people many of those were contacts through the NLnet. Then the folks from NextGraph[2] approached us and asked, "Hey do you want to be part of this consortium [3]?". Eventually we got a HORIZON grant after a lot of sweat and paperwork, but NextGraph took the brunt of it.

As you see there is a huge component of sheer luck

Congrats! But what is a spreadsheet "engine" as opposed to a spreadsheet program?


The "engine" is the computational part of it. And it is completely separted from the UI. You can use it from Rust, Python, nodejs or from the browser and eventually from a destop app.

The important thing is that is all those cases the engine is the same. I


I'm sure it's a great book :).

I find good popular books on higher mathematics difficult to come by. A nice exception is the trilogy written by Avner Ash and Robert Groß:

Elliptic Tales, Fearless Symmetry and Summing it up (in my order of preference)



Mir titles is a feeling. It's nostalgia. It's childhood for many including me. The books are excellent written by some of the finest of their times talking to the lowest highschool level student or even a child and making him or her understand fully what all is going on. Indians love Mir.

My favorite author is Landsberg. He is in Mir titles. He got defeated by our main man C V Raman by 2 weeks to publish the same research (independently) which got C V Raman the only Physics Nobel Prize for India.


Sorry for the stupid question but is Elliptic Tales your favorite or is it Summing it up?


Elliptic Tales, but maybe it is because I read it first


Thanks for the mention! That's indeed the plan


Hi! Congratulations to you and Yousef. And I am lucky enough to be in a position from learning from both of you.

Anyone think what they might about La Suite, but blocknote is a solid product!


Very much appreciated! We put a lot of effort into it!

Aaron Swartz has a nice blog post about it[1].

It's been discussed several times on HN[2]. I had periods I go through without news. It's been harder to do that lately.

I submitted that link. In all fairness the link in this post is more accurate. I'm glad to see people are interested. Let's see where all this goes.
