The Carnival of Mathematics is a monthly blogging round up hosted by a different blog each month. The Aperiodical will be taking responsibility for organising a host each month, and links to the monthly posts will be added here. To volunteer to host a forthcoming Carnival (see below for months needing a host), please contact Katie.

The Carnival of Mathematics accepts any mathematics-related blog posts: explanations of serious mathematics, puzzles, writing about mathematics education, mathematical anecdotes, refutations of bad mathematics, applications, reviews, etc. Sufficiently mathematized portions of other disciplines are also acceptable. An FAQ can be found at the bottom of this page.

Current: Carnival of Mathematics 121by Ioana at Life Through a Mathematician’s Eyes.

Next: Carnival of Mathematics 122will be hosted byEd at Solve My Maths. The closing date for submissions will be 10^{th}May.

**Carnival of Mathematics FAQ:**

### When are the carnivals published?

The Carnival of Mathematics gets published during the first week of the month. Math Teachers at Play, another maths carnival organised by Denise at LetsPlayMath, gets published during the third week.

### I would like to host a carnival at my blog. What should I do?

Check the list of upcoming Carnival hosts above, and then contact Katie to let her know you’re interested.

### Who does the admin for the Carnival?

The Carnival of Mathematics is currently being organised by the Aperiodical. The Aperiodical will be taking responsibility for organising a host each month, and links to the monthly posts will be added here.

### I’ve found a cool maths article that someone else has written. Can I submit it to the carnival?

Yes, but in an ideal world it will be a recent post and should have never been submitted to one of the carnivals before. The best way to be sure of this, if the post is not your own, is to send in only something published since the last edition of the carnival.

### Who decides what gets included in a carnival and what doesn’t?

The carnival hosts. The carnival is just a guest on the host’s blog, and so what each host writes is entirely up to him or her. In general, most carnival hosts will include almost everything that is submitted to them and a bit more besides. However, if they choose NOT to link to something, then so be it.

### Will the Carnival of Mathematics take articles on basic maths?

Yes — everything from kindergarten to cutting edge research is fair game for the Carnival of Math. Basic mathematics can be submitted to either the Carnival of Mathematics, or Math Teachers At Play (as described above), but advanced maths should generally be submitted only to the Carnival of Math.

### Do you accept articles from subjects such as computer science or physics?

As long as there is a reasonable amount of maths content, then yes.

### Is there anything else I need to do, besides submitting my article?

No, there is nothing else you have to do. When the carnival is published, however, you may want to post a link to it on your blog. The carnival host will appreciate your support, and your readers will enjoy a chance to browse what other math bloggers have written.

### Does the carnival have a twitter feed?

Yes. It can be found at @CarnivalOfMath.

Here’s the missing carnival 7, via the Internet archive: http://web.archive.org/web/20110716094553/http://www.nonoscience.info/2007/05/04/carnival-of-mathematics-edition-7/

Thanks!

I had a conversation with Daniel Colquitt on Twitter about #70 and #75. He didn’t realise he had deleted the posts but had just meant to deactivate the blog account. He’s now found the posts and will rehost them.

Ah, as soon as I posted that he’s reposted #70 but #75 appears to be gone for good (and not at archive.org or a Google cache – where else might it be?).

The 56th installment was actually hosted on my blog, not on Sue’s. In any case, thanks for compiling this list.

Rod, thanks for letting us know. I logged in to sort that out but either Christian or Katie has already made the change. The error was certainly mine.

Any chance you want to host the Carnival again? We’re looking for hosts from March 2013 onwards.

There’s nothing here about how to submit. I’ll send to Katie?

There’s a big huge link at the top of the page saying “Click here to submit an item to Carnival 94″.

Here it is again: Click here to submit an item to Carnival 94

Ok, I’m officially embarrassed. (I wonder if I’m blind to blue text when I’m scanning?)

Hi, although #99 is published it still says “Click here to submit an item to Carnival 99″ up above. I clicked there and submitted something for #100. Will #100 find it, or has it gone down into a #99 space where no-one is looking?

Whoops! Yes, it’s in the queue for #100. Thanks for alerting us to the error.
