We've got a free peek at JUPITER WAR, the newest from Neal Asher, out from Tor UK and Night Shade Books. Read it at the link.

I am sharing another Cedric blog post because there is a pig-orc and we have to talk about about how cool that pig axe-hammer is.
Though "Pig-Hammer" is a better word. Pig-Hammer is a grand word. PIGGGHAMMMMMER
http://chaudronchromatique.blogspot.co.nz/2014/04/pig-like-orcs-and-pools-of-evil.html
A brutish pig like orc armed with a pig-axe-hammer:                                And some grotesques pig-orcs spawning from pools of evil.  (liquid evil drip down below into the lower levels of the dungeon).

Combine the quirky beauty of five-fold symmetry with hyperbolic space, and what do you get?  The picture here, drawn by +Roice Nelson!

An dodecahedron is a beautiful shape with five-fold symmetry.  The prefix dodeca means 'twelve', and the dodecahedron has 12 pentagons as faces.

Now, take an dodecahedron and connect its opposite faces with rods.  You get a gadget with 6 rods going through the center. 

Now, build lots of these these gadgets!  Infinitely many, in fact.

Hook them up so the rods fit together and form regular hexagons.  You get the picture shown here.

However, you can't do this in ordinary 3d space, because the angles don't work out.  You need to do it in curved space, where a regular hexagon can have angles that are smaller than 120 degrees.  That's where hyperbolic space comes into the story.  This setup lives in hyperbolic space.

It's called the {6,3,5} honeycomb.  Why?  Read my explanation at Visual Insight:

http://blogs.ams.org/visualinsight/2014/04/15/635-honeycomb/

Puzzle: Say you start at one 'node' in this picture, a place where rods meet.  Say you randomly choose a rod and walk down it to the next node... each rod being equally likely.  Say you keep doing this.  This is the most obvious random walk you can do on the {6,3,5} honeycomb. 

Is the probability that eventually you get back where you started 100%?   Or is it less than 100%?

If that's too hard - and it's quite hard - try the same sort of question with the usual cubical honeycomb in ordinary flat 3d space.  Or the square lattice on the plane!

Melbourne's housing market has broken a record with a median house price over $600,000 for the first time. Though there are some signs the market is cooling. Have you been looking to buy or sell? What's your experience been like?

Oh boy, this brings back memories -- the original "Star Trek" game from the 1970s, played on character-based terminals. I remember playing this on a PDP-11 in the basement of a building at the University of Melbourne. The 'display' was the print-out on tractor-feed paper! Gosh, we must have wasted a lot of paper. But it was a heck of a lot of fun.

I tell you, young 'uns, those were the days!

This version of the ancient program has been resurrected to run on modern computers by Tom Almy, and is in fact the "Super" version of the game. The game I first played was actually more primitive even than this! 

Here's a link if you want to get a feel for what computer gaming was like back in the mid 1970s: http://www.almy.us/sst.html .

We used to do this one in our old university mac lab in the late 80s. http://en.m.wikipedia.org/wiki/Netrek
So many memories as we'd send messages across the lab to each other and giggle like idiots trying to figure out who your opponents wete based on their expression when you nuked a ship. Hee hee
