Hey Guys, Let's Think About Bendalloy Ferrings, Aka Subsumers, For A Minute.

Ok, so after the skyeel came out yesterday, I decided to try a chull today.  I'm not entirely happy with it, but here, have it anyway.

Here, have another of Iredomi's poems!  The text can be found in his original post here on sebrukiscrossbow. 

Last Chance to Pledge for Full Negative Book

Friends. Readers. Fellow nerds with impeccable taste. We are officially in the home stretch. The final 24 hours. The last lap. The dramatic climax of the movie where everything explodes in slow motion and the music swells and someone says something heroic right before punching a fascist in the face. (Okay, that last bit’s just wishful thinking, but after the week we’ve all had, I think we…

Last Chance to Pledge for Full Negative Book

Happy Halloween!

I am a Rithmatist for Halloween this year. I haven’t figured out how to get a good picture of my coat by myself and I don’t have any one around to conscript into playing photographer, so you get pictures from the Shadows of Self release that I’ve been meaning to post and not getting around to for a while. I made Rithmatist coats for @fbstj and I:

Since I’m a Rithmatist (possibly an older version of Melody?), my jack-o-lantern clearly needed to be one of Melody’s unicorns:

More pictures of me in my Coat under the cut.

I really need to do Melody’s circle tracing practice XD

Hi, I'm auditioning for the role of Spook, Survivor of the Flames, and I'll be singing "Village Lanterne" by Blackmore's Night.

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

Ohhh... this looks like fun...

Cinderella's fairy godmother is a lightweaver who sent her spren to the ball with Cinderella to maintain the illusion.  The midnight curfew is there because she could only infuse her spren with so much stormlight and the illusion will fail when it runs out.  Maybe the spren stays with the glass slipper and uses the little bit of stormlight it still has to continue maintaining just that part of the illusion...

Princess and the Pea is an easy one, relatively speaking. The princess in question is a tin-compounding Twinborn who got stuck in a touch loop at an early age. The easiest way I can think of for that to work is that she doesn’t know she’s doing it - perhaps she fundamentally doesn’t understand...

Your questions got me thinking and realizing that I have additional questions:

Szeth is likely going to summon his spren as a sword eventually. Is it going to make Nightblood jealous? Will they see it as a way to destroy twice as much evil? Szeth dual wielding blades? Or Nightblood getting frustrated because Szeth really needs a long spear for a sky battle right now and he is using the sprenspear instead of a sword?

Or, would Szeth summon his spren as a shield while using Nightblood as a sword?

What is the conversation going to be like when Nightblood and the spren talk?

Or, y’all, Szeth and Nightblood and the spren in a sort of threeway poly nahel bond. Maybe the bond could dampen the spiritual cracks in Nightblood so that they don’t automatically suck all of the investiture out of anyone holding them? 

I wonder what it’s like to be Szeth’s spren.  Like, the only thing they have to do is stick close enough that he can surgebind.  Nightblood takes care of everything else.  Did some Highspren just go: “This is gonna be the easiest assignment ever heck yeah” and then sleep through the rest of the book?  Are they annoyed at not having anything to do?  Were they tired of working with more conventional Skybreakers?  What do they think of Szeth siding with Dalinar over Nale?

I have questions guys

I have exactly one (1) lifehack for every adult thing and that is “admit your ignorance to customer service people”

no, seriously! I know how nothing in adult life works, but I have learned it by calling up the customer service division of whatever agency I am having a problem with and then just asking about whatever the problem is, emphasizing my complete lack of knowledge about the thing.

my actual literal script for these interactions: “Hi, my name is [name]. This is my problem: [problem]. I don’t know how [adult thing] works. could you explain how [adult thing] works?” it fucking works every time.

me: I keep getting conflicting information as to whether my therapist is covered by my health insurance. I don’t know anything about health insurance, so this is very confusing to me. could you explain why this might be happening? health insurance customer service: it’s because your normal health insurance is X company but your mental healthcare is subcontracted out to Y company, and Y covers your therapist but X doesn’t. just always bill Y when you go to your therapist and you’ll be fine.

me: I accidentally put the wrong date to pay my credit card off and I’m afraid it will post before I get paid. this is my first credit card so I don’t know what I’m doing. could you tell me when it will post? customer service person: it will send a message to your bank today, but your bank won’t respond to it until tomorrow when you get paid, so you’re fine. and even if it does bounce, the fee is only $25 and you qualify for a waiver.

me: I went to an urgent care place that said they’d take my health insurance, but now i have a big bill. I don’t know how billing works: can you explain why the amount is so much for such a routine trip? customer service person: it’s because you were out of network at the time. however, since your insurance hasn’t covered the cost of care, the urgent care people should refund you for the cost of the services you paid for. me: [gets actual check in mail for the $200 I spent on testing my pee]

I would not recommend this method for retail (for the love of god, do not tell a sleazy car dealer that you don’t know how cars work), and sure, sometimes you have to speak to the manager or threaten a credit card chargeback or whatever you need to do. but 99% of the time, speaking nicely and admitting to needing help has worked wonders for me, and means I don’t have to stew in terror over doing some adult thing Wrong.
