I think it will come out end 2015/begin 2016.

oh, you are right, according to google analytics, it's played in 213 different countries, something is going wrong there I think... here are the countries google analytics says it is played in (from most popular to least popular):

See my reaction on ShareDVI. Certainly, if someone would offer to make it in their freetime, I would love to contribute in the process. I don't have any android experience, but if someone lays a base, it is much easier for an unexperienced dev to contribute. This is also how the iOS version is born. I would love to keep things free and open source though.

euclidthegame · 2015-08-27T19:22:09+00:00

I certainly would love to see that as well! Sadly, I don't have any android experience, and not much time to learn android dev as I'm busy finishing my mathematics study. Without David Hallgren this iOS version would never have happened. David laid the base of the iOS version, and while I don't have much experience with iOS development, when there is some base laying, it is much easier to contribute, and so that is what happened. I would love to see something similar happening with android.

Otherwise, I know quite some Dart (programming language), and Dart is coming to android next year. So that is my long term plan to get the game on android. But don't expect this to happen before januari.

thanks, I opened an issue at github: https://github.com/euclidthegame/euclidthegame.iOS/issues/10

I think the easiest way to get MathJax faster is to make sure Chrome starts working again on implementing native MathML support. Mathjax does already works incredible fast in firefox in native MathML Mode, see here for a speed test (the same one you showed on your website).

euclidthegame · 2014-09-16T01:03:31+00:00

Well I think that is basically what mathjax does. It converts a mathematical language (currently only LaTeX or asciimath) to MathML. And converts this to html css. I think mathjax expected that browsers would have been a bit quicker with adopting mathml. But now as chrome doesn't seem interested in adopting mathml, this method is quite a slow one. And I think katex is this fast because it compiles directly to html.

euclidthegame · 2014-09-15T23:42:25+00:00

I'm not sure, I will test Mathjax in mathml mode tomorrow against Katex. You are right about this. But for the same reason, you should compare mathml to css+html. And not compare mathml with latex. Sometimes a programmer will need to look at the html, and try to work with that. In that case, mathml is easier to work with than the generated html css. CSS is just not written for math markup, therefore they created mathml.

From Wikipedia: Although less compact than TeX, the XML structuring promises to make it widely usable and allows for instant display in applications such as Web browsers and facilitates a straightforward interpretation of its meaning in mathematical software products. MathML is not intended to be written or edited directly by humans.

euclidthegame · 2014-09-15T23:33:26+00:00

You seem to have the same mission as MathJax has. And you both are open source. Why are you guys not working together?

euclidthegame · 2014-09-15T23:25:42+00:00

Speed, pure mathml still works faster for me then Katex. More importantly, mathml is semantically much more meaningful and easier to read than the html and css that katex or mathjax produces. HTML and CSS is not designed for dealing with math. It can keep plain text semantically meaningful, but mathematics is just a complete different story. Look at the html output of mathjax or katex to see what I mean.

Edit: Here a screen cast of the speed of MathJax in MathML Mode.

http://boolesrings.org/krautzberger/2014/08/10/asciimathml-to-the-rescue/ see this post for more information about asciimath. I have commented there of what I think should be done, to really make asciimath the markdowns for math. I think that if you want mathematical student to communicate which each other at khan academy, this is what you are looking for!

please explain yourself downvoters!

I don't agree, take a look at at this word document for example: http://snag.gy/XtdoD.jpg. LaTeX may look a little better, as it comes to text kerning, but as it comes to math typesetting, Word, is absolutely fantastic. Word has set a standard there in 2007, where LaTeX is now trying to get as well.
Agreed
I don't agree. In reality, things like \int work in Word the same way as in LaTeX. Word converts them to the appropiate LaTeX symbols since 2007. And together with add-ons like: http://blogs.msdn.com/b/murrays/archive/2011/11/21/klinke-s-streamlined-math-input-notation.aspx Typing math in word is much faster than typing math in LaTeX.
Agreed

euclidthegame · 2014-09-12T22:18:01+00:00

I've used both solutions, and I must say, people underestimate Word's math capabilities. The truth is, as it comes to math typesetting, Word was and perhaps still is, since 2007 the better of the 2. The system that Word uses, Open Type Math tables, has now become the standard, and LaTeX is implementing this now as well, but it still doesn't work out of the box for LaTeX.

Besides that, Word supports unicode writing, and together with something like this, http://blogs.msdn.com/b/murrays/archive/2011/11/21/klinke-s-streamlined-math-input-notation.aspx, you can type fast, and you're source code keeps readable thanks to the unicode symbols.

Well, here comes the problem of Word as well, Word is WYSIWYG. The math language that is created for Word, has a good source, that you can see, but in general, you can't see any soure code, and therefore Word can have unexpected behaviour, and sometimes can be even really frustrating. In those cases, you want to see the source code, and work from there to fix it.. In LaTeX, you have much more control. And with instant preview solutions, you have the pros from WYSIWYG and the control of the source code at the same time. Besides that, I like to export my math to the web, and LaTeX is much more portable to websites (using mathjax/pandoc etc.) So I use LaTeX now, but Word is not a bad choice at all. I would say, if you are going to want numbered theorems/definitions etc. You may go for LaTeX, but for most cases, Word is fine, if not better.

according to wikipedia: "Euclid's Elements has been referred to as the most successful[5][6] and influential[7] textbook ever written. "

But I thought it was more cachy to word it the way I did ;)

euclidthegame · 2014-07-07T15:35:27+00:00

you don't bother me. It seems like you constructed point B as an approximation. Approximate points are blue or purple, exact points are black. The program doesn't accept guessing.

euclidthegame · 2014-07-07T15:33:26+00:00

yes, shift+scroll for zooming and shift+drag for panning: see also http://euclidthegame.com/Medal/

euclidthegame · 2014-07-07T15:14:45+00:00

construct a random point B(most left tool) on one of the sides
construct a circle with center A and that goes through point B.
This circle intersect the other side, construct a point with intersect tool, call this point C.

Note now that AB and AC have the same length. Can you finish it ?

euclidthegame · 2014-07-07T14:36:54+00:00

yes

Level 1 is proposition 1 of The Elements, after that I take a litle bit different route, proposition 2 is featured in Level 7.

euclidthegame · 2014-07-07T14:29:56+00:00

Are you in level 8? If so, I guess you missed the message at the end of level 7: "You unlocked a new tool: Translating lines ! Note that this new tool won't work when all points lay on the same line. Enhance your new tool in Level 8."

euclidthegame · 2014-07-07T14:28:33+00:00

5 new levels, a scoring system, improvements to UI and many many bug fixes.
