A complete classification could lead to a wealth of new materials and technologies. But some exotic phases continue to resist understanding.
The theory developed here (that you will not find in any other course 🙂 has much in common with (and complements) statistical mechanics and field theory courses; partition functions and transfer operators are applied to computation of observables and spectra of chaotic systems.
Nonlinear dynamics 1: Geometry of chaos (see syllabus)
Topology of flows – how to enumerate orbits, Smale horseshoes
Dynamics, quantitative – periodic orbits, local stability
Role of symmetries in dynamics
Nonlinear dynamics 2: Chaos rules (see syllabus)
Transfer operators – statistical distributions in dynamics
Spectroscopy of chaotic systems
Dynamical zeta functions
Dynamical theory of turbulence
The course, which covers the same material and the same exercises as the Georgia Tech course PHYS 7224, is in part an advanced seminar in nonlinear dynamics, aimed at PhD students, postdoctoral fellows and advanced undergraduates in physics, mathematics, chemistry and engineering.
An interesting looking online course that appears to be on a white-labeled Coursera platform.
I’ve come across Predrag Cvitanovic’s work on Group Theory and Lie Groups before, so this portends some interesting work. I’ll have to see if I can carve out some time to sample some of it.
In lieu of resolutions this year, Cate Huston wrote a set of liberations, starting a movement. My friend Jean Hsu also wrote a liberating, personal list, which is where I discovered it, and Ellen K. Pao has a characteristically thoughtful entry.
I like the framing a lot: rather than creating a set of requirements for my new year, which is what a resolution does, I’m freeing myself from a set. So here’s my list of things I’m liberating myself from in 2018:
Who is really benefiting from the crowdfunding site for artists?
This makes me want to find alternate and more direct means of donating money to people I want to support.
This could be a use case for people to have payment pages on their own websites to make the process more direct. This would also mean that they could post their update content on their own website and use either feeds and/or email to update their patrons.
I haven’t seen a “Patreon” concept on someone’s website in the wild yet, but I have seen examples like Tantek Çelik’s payment page, that do provide a start to the process. Many CMSs already have many of the other moving parts already built in for things like following/subscribing.
The FCC's plan to gut net neutrality deserves a heated response from the millions of Americans who work and create online every day.
Other than the simple “it will spur investment”, what exactly is Ajit Pai’s argument for getting rid of net neutrality? Where is it? I suspect that the only reason there’s no coverage of it anywhere amidst all the turmoil is that it doesn’t exist.
Most communities, even in major cities, only have one provider at best, so there’s absolutely no competition to begin with. Why not start with fixing that first?! In fact, that necessarily needs to be dealt with first before a bone-headed idea like killing net-neutrality.
