And now for my next trick...

Category theory is a branch of math that puts processes on an equal footing with things - unlike set theory, where everything is fundamentally a thing.   Can we use category theory to help understand the complex processes that underlie biology and ecology? 

I believe so, and I'm hoping this is a good way for fancy-schmancy mathematicians like me to help the world.  But it will take a while.  I think we should start by seeing what category theory has to say about some related subjects that are better understood: chemistry, electrical engineering, classical mechanics, and the like.

We're having a workshop about this next week - and to organize our thoughts we've been writing some blog articles.  Check 'em out!

• John Baez, Categorical foundations of network theory - an introduction to the workshop and what it's about.  https://johncarlosbaez.wordpress.com/2015/04/04/categorical-foundations-of-network-theory/

• David Spivak, A networked world.
https://johncarlosbaez.wordpress.com/2015/03/27/spivak-part-1/

• Eugene Lerman, Networks of dynamical systems.
https://johncarlosbaez.wordpress.com/2014/03/18/networks-of-dynamical-systems/

• Tobias Fritz, Resource convertibility - an introduction to the mathematics of 'resources'.
https://johncarlosbaez.wordpress.com/2015/04/07/resource-convertibility-part-1/

• John Baez, Categories in control - about my paper with Jason Erbele on using categories to study signal flow diagrams in control theory.
https://johncarlosbaez.wordpress.com/2015/04/23/categories-in-control-2/

• John Baez, A compositional framework for passive linear networks - about my paper with Brendan Fong on using categories to study electrical circuit diagrams.
https://johncarlosbaez.wordpress.com/2015/04/28/a-compositional-framework-for-passive-linear-networks/

• John Baez, Decorated cospans - about Brendan Fong's paper providing mathematical infrastructure for the study of networks.
https://johncarlosbaez.wordpress.com/2015/05/01/decorated-cospans/

• John Baez and Brendan Fong, Cospans, wiring diagrams, and the behavioral approach - an attempt to reflect on how our work connects to that of David Spivak.
https://johncarlosbaez.wordpress.com/2015/05/05/cospans-wiring-diagrams-and-the-behavioral-approach/

• Brendan Fong, Resource theories - about Brendan's new paper with Hugo Nava-Kopp on resource theories.
https://johncarlosbaez.wordpress.com/2015/05/12/resource-theories/

• John Baez, PROPs for linear systems - about Simon Wadsley and Nick Woods' generalization of a result in my paper with Jason Erbele, describing categories where the morphisms are linear maps.
https://johncarlosbaez.wordpress.com/2015/05/18/props-for-linear-systems/

The picture, by the way, was drawn by Federica Ferraris and appears in this book:

• John Baez and Jacob Biamonte, Quantum techniques for stochastic physics, http://math.ucr.edu/home/baez/stoch_stable.pdf

It's about Petri nets and reaction networks - two kinds of networks that appear in chemistry and population biology.

Okay, Satya Nadella screwed up here, and he's still screwing up.

In his apology he states: "Without a doubt, I wholeheartedly support programs at Microsoft and in the industry that bring more women into technology and close the pay gap. I believe men and women should get equal pay for equal work.

Mr Nadella, you're the freaking CEO. You don't have to "support programmes" to do this. You just have to sign off the budget alteration and equalise pay.

All this dancing around and "trickle-down-ish" crap just proves that you don't support equal pay. You just want to look like you do.

Your Mac's Sound Preference Pane is the go-to place for choosing audio inputs and outputs, but it isn't the only place you can go in OS X to manage your Mac's sounds. Even though Audio MIDI Setup may sound intimidating, it's loaded with controls that go far beyond what its name implies and can help you fine tune the audio quality your Mac pumps out.

Yeah. The super cold stuff gets old fast. I think what's been more annoying is the amount of days they cancelled classes.

Daughter said she wants a baby and I started talking about financial & emotional independence.


Um, she was talking about a doll...
