@vacuou5ly_tru3 @JointMath @amermathsoc @BridgesMathart @MathsArts I think the update to the registration page has just gone through and the cost has been somewhat reduced. Thanks for catching that.

@vyki_e Count WiFi or Bluetooth MAC addresses? They should be randomized these days, so you can’t track, but if all you needs is a count, should work.

@vyki_e My storage management skills need work. For your purposes, apps like Adobe Reader on iOS directly integrate with Dropbox and let you highlight and comment for free (with edits saved to Dropbox)

@vyki_e If the PDF is compiled from scans or random sources, step 1 is usually to OCR/optimize the PDF in Acrobat Pro. After that, pick your poison for editing and reading (Notabiltiy, Noteshelf, etc)

Here’s a lovely puzzle invented by John H Conway in the 1960s. Worth a ponder if you haven’t seen it before.

@_daviddumas Can you “see” the genus, or at least differentiate between them? Also, is it possible to animate a deformation of a cocompact group?

@michael_nielsen @stevenstrogatz Essentially, you can take an example of an optimization, generalize it, prove that the generalization holds, and implement it, all automatically (as far as I understand)

@michael_nielsen @stevenstrogatz Recursion schemes classify some types of recursion and let you abstract them away in code. Possibly recognizing them and optimizing away. The latter is rather cool too, see cs.cornell.edu/~ross/publicat…

@bradelliott23 @TopologyFact @NetworkFact “Topologically” because you can’t require all edges to be straight line segments and have length 1 (or any abstract choice of lengths). However, you can always make the edges straight.

@myopiad That's maddening. Maybe try this workaround goo.gl/DW146P? Also, since you seem to be selecting screenshots, they are collected all together is a special media type album.
