In The Chasms In Way Of Kings, Dunny Creates An Insult Poem By Making The Rhythm Fit The Song Mari’s

1/24 Newnan signing report

*dances around* Not only did I get to meet Brandon Sanderson and have him sign my books, I ALSO got to meet Ben McSweeney (see previous post)!

While hanging out in the bookstore waiting for the signing to start, I met a couple of other fans.  One of them had gotten there early enough to get one of the special "get a seat at the front of the Q+A" wristbands but didn't have a question.  I got him to ask what Horneater stew would be like on earth.  It is apparently based on a spicy Korean seafood soup that traditionally is made by just throwing anything acquired from the sea (shrimp, clams, mussels, etc) into the pot whole, shells and all. He gave the name of the soup. It's Korean. I would probably butcher the spelling completely, so I'm not going to try.

When I got through the line, I asked if he could draw the Blad defense in The Rithmatist.  His response was a look that very clearly said "You expect me to remember which one that is by name?" I clarified and he just kind of laughed and drew me one of the 4 point circles and suggested that maybe I could get one of the more complex ones from Ben.

I asked for something about Kaladin when he was signing WoR.  Before I tell you what he wrote, I should mention that he was halfway through writing it when I opened my rithimatics notebook and kind of distracted him. "Kaladin has known multiple lightweilders." 

So. Rithmatics.  I pretty much just started flipping through my notebook asking questions about each page.  Most of the questions got a simple affirmative. For the other things, I'm paraphrasing: 

Yes, 5 and 8 point defenses could exist.  They haven't really been explored in world though.

You can always bind more than one thing to a bind point, but binding multiple things weakens the point. It is a much better idea to add a small circle that gets 3 additional bind points. It doesn't change anything if the point comes from multiple points in the 9-point construction.

When I showed him the 9-point ellipses constructed from different triangle centers he stared at them for a moment before answering.  He hesitantly said that, yes, those constructions should be valid in theory, but that they shouldn't be used in practice.  The sides of ellipses are weak enough that if you expect to need to defend your sides you really should be using a circle.

At this point he started to say that we shouldn't hold up the line too long as I flipped to a page titled Lines of Vigor.  I was going to let it go, but he glanced at the page and told me to go ahead and ask :D

Yes, Lines of Vigor behave like light waves. (I'm so glad I was right on this)

To clarify I double checked that this means that higher frequency waves are better for doing damage, lower frequency waves are better for transferring energy (and thus moving things)

Yes, Lines of Vigor follow the rule that the angle of incidence =angle of reflection.

GUYS.  LINES OF VIGOR ALSO REFRACT.  I asked it in terms of whether they slightly change speed and direction when they move between materials like, say, concrete and asphalt.  He said yes and that you also get the wavelength adjusting.  Ben then commented that he hadn't known that. *flails*

I got "Oh, wow"'s from both of them while I was flipping through the notebook :-).  At that point, Brandon passed me off to Ben and we chatted about inconsequential things while he took one of my spare sheets of paper from my notebook and drew me a picture *flails more*

I'm still on such a high guys, it's crazy. *dances around*

(very minor edit to fix a typo that was bugging me)

Because Syl would be fascinated by lava lamps and try to emulate them.  Clearly.

Merry Christmas! And I hope that any of you who don't celebrate Christmas have a wonderful day as well :-)

Oathbringer Speculation: Timbre

The descriptions of Timbre would fit with the name “lightspren”. We know that she communicates with Venli by pulsing to different rhythms. During the first shadesmar boat trip, Shallan speculates that the Reachers/lightspresn are using vibrations (ie pulses) to communicate.

This suggests that Timbre is a Reacher, but I suspect that she’s not just any Reacher. We meet Ico in Shadesmar and learn that his father is a deadeye and his daughter “ran off chasing stupid dreams”. Then Timbre tells Venli that her own grandfather was lost to human betrayal. Putting all of this together, I strongly suspect that Timbre is Ico’s daughter. I’m not sure what implications this will have for the future. But it’s a thing.

What was that small spren that had crept out from beneath Eshonai’s corpse? It looked like a small ball of white fire; it gave off little rings of light and trailed a streak behind it. Like a comet. (pg 340) 

“The copper vibrates,” Shallan said. “And they keep touching it. I think they might be using it to communicate somehow.” (pg 931)

 “Wait!” Adolin said. “Ico, I saw something moving back there.” Ico locked the door and hung the keys on his belt. “My father.” “Your father?” Adolin said. “You keep your father locked up?” “Can’t stand the thought of him wandering around somewhere,” Ico said, eyes forward. (Pg 946)

Ico speaking:  “My daughter used to work there, before she ran off chasing stupid dreams.”  (Pg 948)

Timbre pulsed to Irritation, then the Lost. “That many? I had no idea the human betrayal had cost so many of your people’s lives. And your own grandfather?” (pg 1196)

I haven’t heard anyone talking about the land octopi yet

oh god I'm back

I know, I know. I said I’d just step out for a second. Maybe touch some grass. Maybe not scroll for hours through a website that is basically a dopamine slot machine designed specifically for me. But here I am. Again.

So, hi. I’ve been avoiding Tumblr like it’s a cursed artifact because every time I log in, I lose entire days to posts about sad wizards, incredibly niche fandom memes, and, let’s be honest, pictures of adorable cute animals. But I return to you now, at the turning of the tide, because someone at a recent book signing mentioned that I really needed to talk to y'all in some other way than an 'automatic repost from my own site.'

Fair. It was never you. It was always me.

Now, that said, I'm still talking about FULL NEGATIVE, the scifi book that I'm crowding over on Backerkit, because, well, it's still live, and will be until April 11. I am actively trying to convince you all to throw money at it in exchange for an absolutely unhinged space opera full of telepaths, betrayals, sexy spies, and—because I’m me—an aggressively overcomplicated plot full of feelings. If we hit our stretch goals, we get more cool stuff. YOU get a very cool book. (And there is a limited edition, numbered version of the hardcover available that will ONLY be available through this crowdfunding campaign. Once that window is gone, it's gone FOREVER.)

If you like X-Men, Star Wars, Jason Bourne, or just generally enjoy watching characters make terrible decisions in space, this book is for you. And if you don’t like those things… honestly, what are you doing here? Go, live a better life. Read something wholesome. Avoid the pain I am about to unleash.

So yeah. Click the link, check out the Backerkit, and help me make this book a reality. And if you see me reblogging cat pictures at 2 a.m.? No, you didn’t. I’m totally working.

Rithmatics: Part 1

Hello!  I'm rather fascinated with Rithmatics (the magic system in Brandon Sanderson's The Rithmatist) at the moment, which means you are going to be getting a series of mathy posts.  They will all be tagged with #rithmatics .  I've been encouraged to add the cfsbf tag.  If this bothers anyone, please let me know.

In this first post we explore how all of the binding patterns for circular defenses can be derived from 9 point circles. You might be able to get everything from the pictures, but I give explanations as well.

9 Point Defenses

Let's start by talking about 9 point circles.  Start with a triangle.  Absolutely any triangle will do, but for 9 point defenses we want acute triangles (all angles less than 90 degrees) where all of the angles are distinct.  Mark the midpoints of each side and draw in the three altitudes (start at each vertex and draw the line perpendicular to the opposite side) of the triangles.  Mark the points where the altitudes intersect the sides of the triangles (there are 3 such points, one for each altitude).  Note that all of the altitudes meet a single point. Mark the midpoint of each segment connecting P to one of the vertices of the triangle.  This gives you three more points for a total of 9.  These 9 points will be distinct and lay on a circle.

This explains how to get the bind points for any 9-point defense.  However, not all defenses have 9 points.  These turn out to be very special cases of 9 point triangles where some of the points coincide.  

6 Point Defenses

To get 6 points, start with an equilateral triangle.  Any time two angles of a triangle have the same measure, the altitude from the third angle will bisect its opposite side.  Since all of the angles are the same here, all of the altitudes bisect their opposing sides.  This gives us a "9-point" circle with 6 evenly spaced points.

4 Point Defenses

This time we want an isosceles right triangle (you might know it better as a 45-45-90 triangle).  In right triangles, the legs are also altitudes, which means that the vertex at the right angle is also the point where the altitudes intersect each other. It is also the point where each leg "intersects" the other and the "half way point" between the intersection of the altitudes and itself, so it counts as 3 of the 9 points.  The resulting 4 points form a square and so are evenly spaced around the circle.

2 Point Defenses

This is the strangest case.  Here our triangle is degenerate - one of the sides has length 0, which means that the "triangle" is just a line.  To see how to follow the 9 point construction in this case, we can look at a limit.  Start with a really skinny isosceles triangle.  If you follow the construction, you get three points grouped near each approximately half way up the triangle.  The other 6 points are clustered down near the narrow base.  Now pretend the narrow point is a hinge and slowly close it. As you do, the three points in the middle get closer and closer together, the base gets narrower and narrower and the 6 points near it get closer and closer together.  In the limit this gives us a line segment and a circle which uses half of the line segment as a diameter

Shallan's Journey: Chapter 1, In Which an Experiment Goes Wrong

Shallan grimaced as Pattern formed into a sword in her hands. She still wasn't completely comfortable with the idea of wielding a sword, but it was what needed to be done, so she would do it. She, Navani and Jasnah were running experiments on the portals at Urithiru, trying to get a second one open. Prior to Jasnah's return, everyone had been completely stumped, but between the knowledge Jasnah brought back from her time in Shadesmar and her abilities with the transportation surge, she brought new energy to the project. Their current working theory was that they would eventually need Jasnah and Highprince Kalinar working together to permanently reopen a portal, but they wanted to make sure they had things right before Kalinar bound it open. If this worked, Shallan would use the portal to briefly visit Jah Keved and then promptly return to Urithiru. Jasnah was physically sitting in the tower, but was mentally in Shadesmar monitoring and guiding the portal. Shallan slid Pattern into the sword slot and was excited to feel the portal unlock – finally, actual progress! She rotated the fabrial and, as expected the stormlight in the lamps faded. That, however, is where her expectations broke down. As the lamps faded, the room itself seemed to fade until she seemed to be floating in a black void. Once she got past the initial shock she called out “Oh storm it! Pattern, are you still here? Something seems to have gone wrong...do you have any idea where we are?”

Shallan closed her eyes against the overwhelming darkness as she lost her self in the contemplation of what to do next. What would Jasnah do in this situation? She sighed. Jasnah would know how to navigate Shadesmar, and that wasn't something she could do. As Shallan pondered this, she felt a tapping on her shoulder, startled, and whipped her head around hoping to be able to see something in the inky blackness. She was relieved to see pattern glowing gently, “Mmmm, didn't mean to startle... you were getting lost...”

“Well, yes, when we think hard on something we can get lost in those thoughts.”

“Yes. Dangerous here. Lost in thoughts in Shadesmar is lost entirely.”

Shallan considered this. “Pattern, I'm not sure what you mean.”

“Mmmm... Thoughts are Shadesmar... A lie, but a good lie. If you get lost in thought in thoughts you are lost.”

Shallan shook her head. “I'm still not sure I follow, but I'll try to be careful. Do you have any suggestion as to what we should be doing next? How can we get back to Roshar?”

“Look. Your truth is what you see.”

“Look where? Pattern, the only thing I can see is you...”

Pattern took her hand and pointed with it. As Shallan squinted in that direction she could make out... something. At least it wasn't pitch black. “Ok, how do I get there?"

“Mmmm... Lightweavers aren't for traveling... Lie? The best lies become like truth...”

Shallan looked over at Pattern with eyes narrowed in thought as she tried to make sense of what he was saying. “Do you mean that I just need to be sufficiently convinced that I am already there and then I will be?”

“Mmmm.... not sure... perhaps?”

“Well I guess I don't have any better ideas...” Shallan took a deep breath to center herself and tried to focus on believing that she was at that point in the distance that was something other than inky blackness. She quickly realized that as long as she could see that she was still surrounded by darkness, she was not going to be able to truly believe it, so she closed her eyes tightly and tried to block out her skepticism.

Suddenly, she felt herself fall and land on...something...she didn't recognize. When her brain caught up that things had changed and she was once again in a new situation, her eyes snapped open and she quickly sat up. As she looked around, her eyes grew wide – where on Roshar was she? She was definitely outdoors and seemed to be on the ground, but it wasn't any kind of ground she was familiar with. For one thing, whatever vegetation she was sitting on didn't seem even remotely inclined to retreat back into the rock...which...didn't exactly seem like rock, it was too soft. There did appear to be large rocks standing around though... Did she end up somewhere in Shinovar? Shallan knew that they at least had plants that didn't retreat, and maybe this soft stuff was the soil she had read about... She reached into the bag of supplies she had packed in case something went wrong to pull out her sketchbook. Drawing often helped her make sense of what she was seeing. As she did, she thanked the Almighty that her bag hadn't gotten lost somewhere in her unusual journey. That thought reminded her of her traveling companion. She looked around, but didn't immediately see him and, as her heart started racing in panic, she called out, “Pattern? Did... Did you make it here as well?” She was highly relieved to her a sudden buzzing above her and to see Pattern's tangled mass of lines floating down as she looked up.

“Mmmm... still with you... still don't know where here is. Here is a nice pattern though.”

“A pattern?”

“Mmmm... big rocks all around in a circle with rocks on rocks, but maybe some missing.”

Shallan raised her eyebrows as she carefully stood with her bag and sketchbook and began to slowly walk around in wonder investigating the area she had so unceremoniously landed in. She didn't know as much as she wished she did about the Shin, but this seemed like something that might have been sacred to them at one point. It also seemed abandoned and was impressive enough that she should have come across it in her studies. “Pattern... Either we have discovered some long lost sacred site in Shinovar, or...” here she took a deep breath, “or we aren't on Roshar anymore.”

Whrrrrrrrrthwick! Whrrrrrrrrthwick! Whrrrrrrrrthwick! Whrrrrrrrrthwick!

Dumbledore looked up from his desk and frowned at the little silver device that had just started going off. He had many similar devices in his office to alert him of strong magical disturbances at key locations. This one suggested that something significant had just happened at Stonehenge. Thankfully it was just whrrrthwiking - if it had been shrieking that would have meant dark magic and likely that Voldemort had decided to come out of hiding. This, however, was just intriguing. He glanced back down at the paperwork he had been filling out and shrugged. It could wait. He looked over to his phoenix, “Fawkes, my dear old friend, would you be up for a visit to Stonehenge?” Fawkes chirruped and cocked his head. “Something seems to have happened there, and, beyond the fact that I am curious, it would be prudent to investigate.” Fawkes stretched his wings and trilled as flew over to Dumbledore who stood reached out for his tail feathers. They vanished in a flash of fire.
