What is his facorite color?

142 Benzoyl Peroxide splits into a free radical and starts an anti-markonikov reaction

No. This is because the forum was updated last year and Mr. admin is not free to install the appropriate patches and tweak things to make things possible. bobbym is only a superior moderator with higher powers but no access to the server files and forumware. That's like God and his angles

I also had a solved award and Tigeree was a legendary member

Does Ohm really fit into the rest of the five?

That's interesting. Thanks

First of all, if 16 is in a square with 3 or 4 adjacent squares then one of its neighbours will be at least 3. Thus there will be a sum of at least 19.

Otherwise, 16 is in a corner. We prove that then the maximum sum will still be at least 19. If 3, 4, 5 etc is adjacent to 16 then QED. Suppose 16's neighbours are 1 and 2. Then wherever 15 is, it must have at least two neighbours other than 1 or 2. Thus 15 must have a neighbour at least 4 in value, and the sum would then be 4.

But how does the proof ensure that, say, 14 and 11 are not adjacent?

Hi phanthanhtom;

Is this is a problem about the extremal principle? If it is a proof question, please post the expression: reverse engeneering the answer might be easier

Hi zetafunc;

Thanks for the video.

Unfortunately most of the idea dodged above my head. Can you do a video explaining contour integrals for a complete beginner to the technique?

Hm, tell me about Contour Integral

I am not sure what you mean

Neither do I

Hurray!

I do not think that the programming of games is simple. First, you should learn the language thoroughly, then do the games.

True but everybody can still do some of that. Also, learning and coding is a concurrent process.

I agree with Gourish's idea of having a strong motivation to learn by having a project in hand.

but i do not know how to begin, are there any sites which can help me out?

Probably many. Have you decided what kind of game you're willing to make?

Hi Gourish;

I hope programming becomes a rewarding activity for you and you gain various insights about life from it.

i hope you guys can show me the right direction

Let me know what I can help you with but the best thing I can tell you is that one learns coding only by experimenting.

Thanks.

Wasn't it a bit tough?

I came across this game or puzzle where your phone number tells your age. It's as follows:

It is not a game. A game is a situation where self interested agents interact.

It is not a puzzle. A puzzle is a game with a dominant pure strategy

Are there any proofs?

**Agnishom**- Replies: 10

a, b, c are positive.

a, b, c are real.

a*b*c = 1

Prove or find counterexamples:

a/b + b/c + c/a >= (a+b+c)/3

What holidays?

Meaning?

Do you know how to combine impedances in parallel?
