HSE
i am working on a wikibook 'From Data to Insight' that is about the level of HSE, but you don't seem to have a chapter on 'statistics'...any reason why not?

Love your HSE book! Hope you update it soon :)

Hey :) I changed your modifications to Discrete mathematics back, sorry: there is already a link to intro logic. I'm trying to keep the intro section to have info that will give one the basics of the topics, and the upper level section to be the ideas and concepts that build on the intro topics.

Hope you don't mind :) Dysprosia 02:50, 13 Sep 2003 (UTC)

Question for you on Talk:HSE Primes Dysprosia 22:08, 20 Nov 2003 (UTC)

Some helpful hints
 * x\quad y = $$x \quad y$$
 * x\qquad y = $$x\qquad y$$
 * x^{x^x} \pmod{12} = $$ x^{x^x} \pmod{12}$$

hi xiaodai,

i've been on wikipedia for a while, but only had a look at wikibooks since i need to code Basic Polish language course into my carbon-based processor/soft-disk ;)

Looks good, and nice to see the HSE stuff you're doing. Say hi to terry gagen for me. :)

HSE!
Love your HSE book, thanks so much! I usually feel as if I have exactly enough hints to think about something for a few minutes, and then think Eureka! ;)

For the programming section, I think I could help (see my Livejournal) if you want Lisp/Scheme (go Scheme!). Haskell is the only other mathematically-oriented language I can think of - are you planning on using that?

Oh - and aren't Venn diagrams best suited in the logic category? R3m0t 17:35, 5 Dec 2003 (UTC)

I'm glad you liked HSE so much! I'm trying my best to do a good job, but as so often is the case in my first drafts, glaring spelling and grammar mistakes seem to plague my work. Lucky you pick them out for me.

I do not know enough about Lisp, Prolog, Scheme (never heard of it) or Haskell to decide whether they are suitable for high school students or not. If you think a coherent course can be taught using one of those languages, then please go ahead! Create a new chapte if you have to. But I was thinking of teaching a more conventional language like Pascal. Anyway we are not just writing about programming, but mathematical programming. Haskell seems to be a good choice, but where can I find a good programming IDE/compiler for it? I simply haven't done the research.

And nice to meet you. How do you do?Zhuo Jia Dai


 * Just being a stickybeak, but
 * If you want Haskell, the Glasgow Haskell Compiler is an excellent Windows/*nix based Haskell interpreter and compiler environment. Some systems may only run the Hugs system. I'm about to go to bed so I can't give you an exact link but I'm sure you can google it :)
 * Haskell is a good choice of language for pure, functional programming. It's not quite the best language for exploring mathematical concepts in since it's a strict functional programming language. You may want to concentrate on looking at programming in common Computer Algebra systems such as Maple and Mathematica (I do know both systems, but Mathematica's better) for stuff like numerical approximations and all that funky jazz. Haskell is nice for exploring recursion, but more conventional looping structures are easier taught in some other language. With teaching Mathematica (You guys should still have it at Sydney, right?) you get the best of both worlds, really.
 * HTH :) Dysprosia 11:59, 7 Dec 2003 (UTC)


 * Think free. Learn free. is the Wikibooks concept, but Mathematica seems to be a commercial thing. I wouldn't encourage people to use a propriety language on Wikibooks. Wikipedia: Lisp programming language Scheme programming language Haskell programming language Maple computer algebra system Mathematica Maxima Computer algebra system r3m0t 19:58, 7 Dec 2003 (UTC)


 * It doesn't mean we can't teach non-free software, at all. And it's not exactly proprietary software either - it's well used. I merely mention this to Xiaodai as an option. In any case, are we to forbid the creation of a Windows guidebook here because it is non-free software? We cannot be bigoted on the forbidding of teaching just because of its origins now, can we? Dysprosia 21:43, 7 Dec 2003 (UTC)


 * A Windows guidebook would be created for users of Windows who wish to (manipulate/configure/whatever) their installation. By teaching Mathematica in a textbook not created specifically for teaching Mathematica, that is encouraging people to use Mathematica. Lisp, Scheme, Ruby, Haskell seem different to me - it is hard to make any money out of them (plenty of compilers or interpreters are free already) so it's offering a choice of compiler, etc. r3m0t 21:55, 7 Dec 2003 (UTC)


 * I'm going to reply to this at Talk:HSE Mathematical programming, to stop cluttering up Xiao's talk page Dysprosia 23:00, 7 Dec 2003 (UTC)

Hi, are you from China or Taiwan? Do you speak Chinese? Could you help improve text book Chinese? Thanks! --Yacht 09:12, 13 Dec 2003 (UTC)


 * 我的中文不是很好, 好像帮不上什么忙.


 * How could he possibly be from Taiwan? His name is in Hanyu Pinyin. --Menchi 10:43, 13 Dec 2003 (UTC)

*waves*jumps up and down*
Could we consider showing two or more languages side-by-side for the time being? Also, please read over my beginnings of an introduction. Is it too compicated/too much detail/etc? r3m0t 15:15, 13 Dec 2003 (UTC)

Well I read it, it reads ok, except i think the command line and how to issue command part should be clarified upon. I think it's pretty confusing for someone who is not highly computer-literate.Zhuo Jia Dai

HSE is great
Your HSE book is great, it's easy enough to read at a reasonable speed and difficult enough to be challenging. I tried to read several real books but those weren't as fun to read because I had to stop regularly to check if I understood everything correctly. So, thanks for the book.mmartin


 * Thanks, but you may only have read the first chapter, the rest are still horrible. I think they need huge improvements. Xiaodai 22:40, 19 Jul 2004 (UTC)


 * I actually started with the third chapter because I already knew everything in the first one and the second one seemed less interesting. But I agree with you that it can still be improved, although it completly readable for me.(17 year old highschool student)mmartin 24 Jul 2004


 * Thank you very much for your feedback, much appreciated. Xiaodai 03:13, 25 Jul 2004 (UTC)

Attention! Attention!
I would like to inform you that I've come up with a alternative solution(actually the final answer is less complex) to question 4 in logic-problem set. Click here to go to the talk page to see the solution

And also, Nov 21st is coming soon, and does that means editing work are going to be restarted to full strength soon?


 * Yeah, uni holidays starts now and i will do more editing than during the semester. What does "more" mean? I'm uncertainty. See how it goes. Xiaodai 09:10, 20 Nov 2004 (UTC)

Concerning logic puzzle item deletion
Concerning the 5th question in logic-problem set page... Yes, I do agree this question is out of ability for most people, but I think may be at least you put it in the logic puzzle page? This way it has a place to rest. (And consider I spent some good time thinking hard and finally managed to come up with a solution--when I wrote and submitted it, the system kicked me out so the history page didn't log down it was me who submitted the solution)


 * Hmmm, i mean this problem is a bit out of reach. Thanks for contribution and i am sorry that i have to take it down. But the question is just so out of left field and you dont necessarily have to use the techniques taught in the chapter to do it properly. So i need to delete it. Congratulations on being able to solve the problem though, it's a tough one, you must be a genius. ^__^ I will put it in puzzle's page then Xiaodai 12:42, 20 Nov 2004 (UTC)

Nominated!
I'm excited to see that the book "High School Extensions" get nominated for march book of the month. Let's hope we'll win!

Also, I would like to inform you that I've written a starter-a stub, for the discrete probability part. I want to learn some more about it. And I've came up with how to write the starting, so leave that to me as I'm having holiday now and have more free time to do it. Thanks. --Lemontea 13:10, 5 Feb 2005 (UTC)


 * Thanks for that, i didn't know. I am to be nominated, but i feel this book still needs alot of work. Also, i am very much looking forward to your work. Xiaodai 00:04, 6 Feb 2005 (UTC)

Puzzles/Logic puzzles/5 Houses
I have just cleaned up the page a bit. However, the puzzle as it stands is impossible, so obviously you made a mistake/omission in copying it. Please see Talk:5 Houses and then make corrections.

Also, the point of puzzle books is to challenge the reader. By putting the solution on the puzzle page, you are depriving the reader of this challenge, in which case what was the point of giving us the puzzle in the first place? I have cut and pasted it onto a solution page. I haven't cleaned the solution up, since I for one would like to have a go at the puzzle once it is complete. -- Smjg 17:52, 14 Feb 2005 (UTC)

Well, I'm the one who wrote the solution, and Xiaodai just copied it to the puzzle page, so at most he is responsible for copying it to a wrong place.

As for the content of the solution, I looked at it and remembered that my school's maths club did mentioned this problem on club meeting, and I remember that the detail are different. I quickily find out that the question itself has mistake, and I just searched and choose a random complete version of that question.

Anyway, the task to do now is to find out who wrote the question in the first place, and which version of the question should we use.--Lemontea 12:30, 17 Feb 2005 (UTC)

Vote too late
Hi Xiaodai. I just want to let you know that your vote for the book of the month for Mandarin Chinese was 37 minutes after the deadline, and has not been counted therefore. I encourage you to vote again in the current voting for April 2005, as soon as possible, since early votes seem to have a steering effect. Thanks, --Andreas 13:37, 1 Mar 2005 (UTC)

Withdrawing adminship request
I'm surprised that you withdrew your request for adminship after waiting only five days. You had two votes of support already (you only need four), and they do say that the process could take months. I've been waiting for over a month, and that's not unusual (things move pretty slowly in Wikibooks). (Donovan|Geocachernemesis|Interact) 11:26, 16 July 2005 (UTC)

Template namespace
I moved a page out of the Template name space and now I feel bad. If you wanted the page in that name space I apologize. If you had it there because you wanted to be able to include it here is how you include pages in the main namespace, just put the page name as it apears in curly braces with a preceedin colon as below. The book is great by the way! Msmithma 05:35, 17 November 2006 (UTC)
 * thanks, i learnerd something. Xiaodai 10:07, 17 November 2006 (UTC)

Welcome back
Greetings! I noticed your edit summary on your most recent contribution: "i will have the time and energy to start editing again soon. hopefully improve the quality by heaps. so it's more deserving of a recognition." Currently images without proper licensing and sourcing are being deleted. I noticed that many of yours are without a license or a source. If you would consider licensing them under an appropriate license (GFDL, PD, CC, BSD) and a source (yourself, I assume) I would greatly appreciate it. I noticed that many of your images are still be used! It would be great to be able to keep them.

And don't worry: you don't have to go through every image description page and tag it manually. You may ask an administrator (try User:Whiteknight) to run a bot to tag them all simultaneously.

Again, thank you very much, and welcome back! --Iamunknown 03:48, 23 January 2007 (UTC)

Help!
Hi Zhuo Jia Dai]].

I'm probably not doing this right, but I can't see any other way. I'm new to Wikibooks and am just trying to send you a message.

I would like to help with your High School Mathematics Extensions with an addition, or possible follow-up, to your Set Theory and Infinite Processes. I have read your Chapter and like it (and have a couple of suggestions).

Here is the introduction to a ten-page sample I've written: "Cantor’s diagonal method is elegant, powerful, and simple. It has been the source of fundamental and fruitful theorems as well as devastating, and ultimately, fruitful paradoxes.  These proofs and paradoxes are almost always presented using an indirect argument.  They can be presented directly.  The direct approach, I believe, (1) is easier to understand, (2) unifies the proofs and paradoxes by exhibiting a single strategy, (3) shows Russell’s paradox to be the (obvious?) ultimate, set theoretic application of the method, and (4) is extendable to some of the semantic paradoxes."

If you're interested, please contact me; I just registered with Wikibooks, and maybe that allows you to contact me, but I wouldn't know where to look for your response. So please email me at TomSchaffter@Mac.Com.
