4:55 AM | Space and stochasticity in evolutionary games
Two of my goals for TheEGG this year are to expand the line up of contributors and to extend the blog into a publicly accessible venue for active debate about preliminary, in-progress, and published projects; a window into the everyday challenges and miracles of research. Toward the first goal, we have new contributions from Jill […]

10:59 PM | NetEcon 2015
Patrick Loiseau, Adam Wierman, and I are co-chairing the 2015 NetEcon workshop, to be held in conjunction with EC and Sigmetrics at this year's FCRC in Portland. You should stop by if you are attending any of the FCRC conferences, (and submit a paper). If you haven't been to a previous iteration, this workshop brings together people interested in game theory from both the networking and theory/AI communities, so is a great place to present work that might be of interest to both […]

Re: Peirce List Discussion • Howard Pattee A computational problem is defined as a set of problem instances with specified characteristics.  An algorithm solves a problem if it computes the correct answer to every problem instance in that set. The use … Continue reading →

7:43 PM | A Non-Noetherian Subring of a Polynomial Ring
Sometimes there are wild beasts hiding in the tamest of rings. Let’s flush one out! Let $k$ be a field. Consider the following subring $R$ of $k[x,y]$ consisting of polynomials all of whose monomials are never of the form $x^i$ for $i\geq 1$. So $f = xy + y^2 + x^2y\in R$ but $f = […]

5:01 PM | The name of the rose and the smell of the article
“A rose by any other name would smell as sweet” wrote Shakespeare.  Yes, but an article about the rose’s smell wouldn’t smell as sweet at all. The form of the article as a mean for disseminating research is more and more questioned. I liked  Idiot things that we we do in our papers out of … Continue reading The name of the rose and the smell of the article →

3:43 PM | On Barthes’s “Introduction to the Structural Analysis of Narratives”
I feel I may have been a little unfair in choosing “From Work to Text” last post. In the same collection of essays, Image – Music – Text, is a much better introduction to what Barthes is known for: (post-)structuralism. … Continue reading →

6:49 PM | “They are artificial microbes that can be created to make …”
My brother  Dragos Buliga, a sharp film director and media producer, asked me to describe to him in lay terms what he sees in these demos pages. I came up with this. (See more at chemlambda vision page.) They are artificial microbes that can be created to make a computer do anything without knowing what … Continue reading “They are artificial microbes that can be created to make …” →

Trial in Medical Research Scandal Postponed By Jay Price DURHAM, N.C. — A judge in Durham County Superior Court has postponed the first civil trial against Duke University by the estate of a patient who had enrolled in one of a trio of clinical cancer studies that were based on bogus science. The case is […]

8:43 PM | A nice problem from a Romanian Math Problem Book
(All of the math for this problem is here)My Discrete Math Honors TA Ioana showed me a Romanian Math Problem book(She is Romanian) and told the following problem: (All ai in this post are assumed to be natural numbers) Show that for all n ≥ 6 there exists (a1,...,an) such that 1/a12 + ... + 1/an2 = 1. (sum of reciprocals squared) Normally my curiosity exceeds my ego and I would look up the answer.But it was in Romanian! Normally I would ask her to read the answer to me.But I was going out […]

I’ve posted the beginnings of what I hope will become an extensive library of videos, papers, notes, and slides exploring in more detail both illustrative case studies and theoretical foundations for the universal laws and architectures I superficially referred to in my previous blog posts.  For the moment, these are simply posted on dropbox, so […]

6:24 AM | Helping Students Experience Genuine Mathematical Investigations
A talk for the BSU mathematics department on January 22, 2015. Abstract: In this talk I’ll summarize my efforts to involve students in projects that replicate the math research experience. In particular I will discuss a set of projects and corresponding curriculum (adapted from another university) for Math 287. The projects require students to ask questions, formulate conjectures, investigate them in groups, and express their findings in writing. Investigations of this type are […]

9:23 PM | Annihilator: Hollywood, the galaxy and everything
by @ulaulaman a review of #Annihilator, a #cosmic #comics by Grant Morrison and Frazer Irving Rabbits are animals extremely prolific, almost legendary in their rate of reproduction, so that Leonardo Fibonacci, thanks to these cute rodents, discovered (or re-discovered) the series that bears his name: 1 1 2 3 5 8 13 21 and so on, and where each number is the sum of the previous two.However, it is astonishing to note how pervasive within nature this series of numbers is: we can find it, for […]

9:03 PM | Nassim Taleb Graphic
This arrived a couple weeks ago from Nassim Taleb. Regardless of where your view falls on the black swan spectrum, I hope you'll like the graphic. One hallmark of a good graphic is that it repays careful study, as with a good map (which is a good graphic). Nassim's Genealogy certainly passes that test. I found myself thinking about its contents and assertions for a long time. (You can blow it up in your browser by clicking on it. That should do the trick, but if it's still not […]

Rob Calderbank is a mathematician of great caliber in coding and information theory, including its algebraic aspects. He is the winner of the Shannon award and the Hamming medal. Rob's 60th birthday celebration will be in La Jolla this weekend. He was a terrific mentor to me at AT&T in years long behind us, and I am looking forward to being at the celebration!

9:51 AM | Il (non) carnevale della fisica #5
E siamo giunti, con l'ultima domenica di gennaio 2015, alla quinta edizione del (non) carnevale della fisica, appuntamento che, spero, sia atteso da sempre più lettori. L'introduzione di questa edizione è dedicata a Philipp Eduard Anton von Lenard, che ha vinto il quinto Nobel per la fisica, nel 1905, per il suo lavoro sui raggi catodici.Nato il 7 giugno del 1862, iniziò a interessarsi dei raggi catodici nel 1888. I raggi catodici sono un fascio di elettroni prodotti all'interno di un tubo […]
