“Third-party extensions and hacks are a part of the web, perhaps Tumblr should focus on building new features or its own official “app store” instead of whining about support and server issues.”
— Drew Olanoff of The Next Web has Jeremy Cutler’s back on Missing e. (via shortformblog)
I’m still using Missing e…
…and have no plan of giving it up anytime soon…

Wronskian differential formula for confluent... →
arxiv-nlin:
Authors: David Bermudez, David J. Fernandez C., Nicolas Fernandez-Garcia
A Wronskian differential formula, useful for applying the confluent second-order SUSY transformations to arbitrary potentials, will be obtained. This expression involves a parametric derivative with respect to the factorization energy which, in many cases, is simpler for calculations than the previously found...

I wish I got paid to be on tumblr!
Then I could make awesome posts for Proof all day! And wear my PJs!
hmmm…anyone want to pay me?

Shopping Goes Geek in Wolfram|Alpha
wolframalpha JUST TOOK SHOPPING TO A WHOLE NEW LEVEL! :O
wolframalpha:
We’ve taken the strengths we’ve developed in math, science, and socioeconomic data and created something equally unique and useful for online shoppers. Type in the name of a product category—”dishwashers” or “tablet computers,” for example—and Wolfram|Alpha generates a comprehensive, custom analysis. What are the typical...
p3ar asked: I'm looking for a type of design that I can only describe as organic life meeting geometry. I'm hoping to find something made from math that resembles a mandala. Do you know of any artists that utilize computer programs like Wolfram to generate the kind of image I'm imagining?

I just spent 45mins on the phone with AT&T because they thought I wouldn’t notice them doubling my internet bill FOR NO REASON.
Maybe they just don’t know math! :/
The Laplacian lattice of a graph under a... →

Authors: Madhusudan Manjunath
We provide a complete description of important geometric invariants of the Laplacian lattice of a multigraph under the distance function induced by a regular simplex, namely Voronoi Diagram, Delaunay Triangulation, Delaunay Polytope and its combinatorial structure, Shortest Vectors, Covering and Packing Radius. We use this information to obtain the...

Quantum computing device hints at powerful future... →
scinerds:
It uses the strange “quantum states” of matter to perform calculations in a way that, if scaled up, could vastly outperform conventional computers.
The 6mm-by-6mm chip holds nine quantum devices, among them four “quantum bits” that do the calculations.
The team said further scaling up to 10 qubits should be possible this year.
Rather than the ones and zeroes of digital...
