8e2bb6856d Fixed error in latex 
It rendered fine in the notebook, but \text{foo_bar} was causing
an error in the pdf generation. Switching to \mathtt{foo\_bar}
mostly fixes it (though in the notebook it renders as -, not _.
Oye.

800ea6c189 Cleaned up equations for UKF. 
I was using a bunch of variable names that weren't consistent
with the rest of the book (but perhaps are more consistent with
the literature). It just made everything more challenging than
it needed to be, so instead of \mu and \sigma (e.g.) I use
\bar x and \bar P.

I also am in the middle of rewriting some sections for clarity,
but that work is not completed.

6b9b97927d Redid Discrete Bayes animations. 
I added titles so you can see where in the processing the
graph is.

This surfaced a bug in matplotlib 1.5 (#5399) so I added
some code to work around that.

* integrals should have "du", etc. (right??)

* $\mathit{VAR}$ gives better spacing than $VAR$

* I find "within $1\sigma$" to be ambiguous; "within $\pm1sigma$" much more clear

* Changed dashes in text from hyphens to em-dashes

* Changed (some) straight quotation marks to curly ones (and removed single quotes in favour of double ones)

* Improved "°C" to just use a text symbol

* Assorted random typos, etc., but avoided rewording anything except for one particularly difficult sentence

122fe27680 changed from \bar to \overbar for prediction. 
More visible, and works better with things like matrices.

ab33584a0c Minor copy edit and code clean up. 
Biggest change was changing the variable for noise to use
either std or var.

b2a3ce2a28 Major rewrite of matrix exponential section. 
I was conflating thematrix exponential with Taylor series, making
the whole thing quite confusing.

There was also significant duplication of content, such as presenting
the calculus form of Newton's equations multiple times in slightly
different ways. I've made it all hang together now.

5ffd42a25d Fixed FilterPy versioning check error. 
The code only worked for the third version number. If the first
or second version numbers were too small it didn't detect it.

be up to date.

0236af896d Added text for computation of velocities. 
I explained how the covariances are computed by FPF',
and then how the velocity is computed using the kalman gain.

77ba700e39 Revised particle filter chapter. 
Pretty happy with it now. Needs copy editing, and probably an
easier introduction to convey the basic idea. Moved from a class
based approach to a procedural approach, and I like that very much.

I mistakenly stated that it re-estimated the points between times
j and k, when of course it recomputes only a single fixed point.
