sorry for flooding the home page, but some pending crap had to be cleaned up.

Does Mathematica support class like in C++ and java?

@novice There are no language-level constructs for such functionality, but that doesn't really prevent creating "object-oriented" programs if you insist.

Well, folks, it looks like my breakaway years of freedom are drawing to a close. I'm likely being forced to return to .NET development. I might get to use Mathematica to process some spreadsheets as a "business analyst". Perhaps joy is too much to ask for from life. Our civilization has only managed to achieve comfort. I plan to wear a shirt that says, "Hey boss, if you knew Mathematica you could have already saved enough money for an airplane." Or maybe he or she will already have an airplane.

Happy New Year.

can any one help me in this ?

First you need to write out all of the axioms you want to use. Here are some common ones: wolframscience.com/nksonline/page-773

yeah, thanku .

based on standard notations i wrote in that form.

Now use your axioms to derive all statements that can be proved from your initial statements in one step. Then repeat this until you find the statement you want, the statement that it is false, or you get tired of waiting.

:) . yeah u are correct.

@MichaelHale happy new year! But your shirt should wear: "Hey boss, your lack of Mathematica knowledge funded my airplane (and a shiny one it is, too)"... well, one may but dream :D

True, that does sound better.

I'm having problems reproducing a figure in the documentation under tutorial/NDSolveSPRK. Cell tag s:3 has an electrostatic wave example; however if I evaluate the two cells under equation 7, I do not get the figure that is in the original documentation. Can someone confirm this behavior?

@bobthechemist I get that same shape.

@Calle What version of M are you running and on what system?

@bobthechemist 9.0.0.0, OS X

thanks

I think it would be nice to have a quasi official message from all of us to all of us here in chat wishing us all a happy 2014. How about we try to upvote the first message here after 00:00 coordinated universal time (UTC)? That would make it a nice game too :). Note: If you are going to write a script to do this, make sure you do it with Mathematica, or it will not be heartfelt ;) :P.

If the prices for the Wolfram Cloud are cheap enough we could switch the chatroom environment to a computationally generated forest of simple 3D program visualizations and explore it with our avatars. We could each just run Dynamic@StackExchange`MMORPG[] and send it commands to update the environment state.

I guess we'd have to manually set the UpdateInterval.

@JacobAkkerboom We could write both scripts :) (for posting the "Happy New Year" msg and upvoting it)

@MichaelHale Sorry for you. Mainstream programming languages always sucked. It could've been worse a few years ago (Cobol, Fortran, RPG, ...)

@belisarius Hello, Jesus

@rm-rf Hello frog! HNY!

@belisarius HNY to you too!

I can't believe the site is almost 2 years old (in approx. 2 more weeks)!

@rm-rf Just sent a request for the W Cloud pre-release. Participation slots are full. Are you in it?

@belisarius No... I remember sending in a request a long time ago for Mathematica Online and nothing came of it. Although I would love to participate in the pre-release for Cloud/Mma Online, I doubt I can get in at this point by just submitting my name and email.

@rm-rf Two years! (in spite of the mods!) great! :)

@belisarius :D

@rm-rf Link it to your Mma.SE profile :)

@belisarius I did :(

@rm-rf Well, now we know :)

@rm-rf I starred your msg, hope you received the "First" hat :)

@SjoerdC.deVries Hi there! HNY!

Hi there. Checking in on my iPhone. Forgive the spelling errirs

@SjoerdC.deVries Hi-tech, low literacy

@rm-rf I tried to better earn the votes I got on this post. (I couldn't comment there because you killed all the comments.)

Hi wiz

@Mr.Wizard there's an answer of mine that I would like to be deleted

Hey @Sjoerd! :-)

@SjoerdC.deVries Which one?

I believe it's one of the most recent accepted ones. That's the reason I can't do it myself.

It is incorrect I suppose?

Answer is wrong because I misread the op's code

He had an l which I read as a 1

Do you know why he Accepted it?

It looked like it was working

I have been trying to crack the correct one to no avail

Post deleted as requested.

Good luck on the "new" problem.

Thanks

Back to family and friends. Best wishes folks!

@SjoerdC.deVries Same for you. Drink safe!

@Mr.Wizard I removed them because it was just a conversation between you and me and those comments (with the remaining ones) made no sense after your update.

@belisarius I think it's the best paid generalist situation I can get given the current distribution for platform adoption. This time around I'm telling the lady managing my contracts to sort them by the amount of data mining, report generation, UI prototyping, etc. because that will correspond to how much of the job I can do with Mathematica.

She said more of them are opening up to letting contractors work remotely once they get comfortable with them, so it might not end up being too big of a lifestyle change.

@belisarius safely drunk so far. HNY everyone!

@rm-rf I didn't say you shouldn't have; I was just explaining the non sequitur comment here in Chat. :-)
