These are the #stories of #math that we celebrate, amplify and make central to the idea of #maths as a #objective #neutral #culture-free subject. #Math can do no #harm, and the #logical “pure math” thinking of #Mathematicians is worthy of emulation. But... 1/x
2/x ... "What about pure mathematics and mathematicians who merely prove theorems? Is there any #ethical component comparable to what you find in other fields of #science?" - R. Hersh in Experiencing #Mathematics
3/x One point of view: "there's no need for #mathematicians to have a code of #ethics, because what we do matters so little that we can do whatever we like."

Drawing Innovation: @illumina Super-Resolution Optics

Recently, $ILMN unveiled the NextSeq 2000, a mid-throughput sequencer w/ a ~2X reduction in operating costs ($/GB).

We think the upgrades inside the NextSeq 2000 may soon enable a $100 clinical-depth human #genome.

But how?
The cost savings come from (1) a new upfront #chemistry and (2) super-resolution optics. We think @illumina will use real-world customer data on the NextSeq 2000 to optimize 1 and 2, then possibly upgrade the #NovaSeq line.

I'm going to briefly (!) illustrate how #sequencing (*by synthesis*) works, walk through a farming analogy, then dive into some technical details. (Sources at the end)

Below is a general overview of a whole genome sequencing workflow (sample in, data out).

Today's Applied Complexity Symposium begins with a panel on Computation and Complex Economies, feat. Rob Axtell, Joshua Epstein, @C4COMPUTATION, Blake LeBaron, John Miller, & @MelMitchell1

(Follow this thread for live coverage all day...)

#complexsystems #economics
4 Principles of Collective #Computation:

1 Ground truth (objective reality)
2 Effective ground truth (what we agree on, whether or not it is accurate)
3 #Information can be collectively encoded in #networks
4 Outputs are a product of collective dynamics

@C4COMPUTATION right now
"I think #economics really needs to adopt a generative framework with agent-based models of cognitively plausible software people...[and] we don't choose to fear."

"Information theory, predictability, and the emergence of complex life"

SFI Seminar by Luis F Seoane of @IFISC_mallorca, streaming now:
"The size of the #environment in some ways captures the #complexity...longer words take longer and longer to sample. This means in smaller environments, smaller words mean more."

- Luís Seoane of @IFISC_mallorca on #information right now:

"More-complex bit guessers are going to survive in a wider variety of environments. But a more-complex guesser is going to pay a higher metabolic cost."

- Luís Seoane of @IFISC_mallorca

Modular, hierarchical, and information-processing:

Right now at SFI, biologists, physicists, neuroscientists, and computer scientists convene for a three-day workshop on Biological #Computation, organized by David Wolpert, @C4COMPUTATION, & @albert_kao.

"A circular definition isn't worthless if the circle is big enough."

- @livcomp of @UNM at today's #biocomp workshop
"#Physics produces order through the minimization of #energy. Adaptive systems produce order through the addition of #information processing."

By why do biological systems compute, whereas classical physical systems apparently don't? @C4COMPUTATION on #function at #biocomp now:
