What do Pulsars & Rock Bands have in common?
This is a story from one of my favorite code-blogs - Archery: http://goo.gl/sw1LDS

Look at the cover of the album "Unknown Pleasures" by 1970s English band Joy Division::
http://en.wikipedia.org/wiki/Unknown_Pleasures

This hand drawn graph with its own cool story plotted in the style of a waterfall plot, in the Cambridge Encyclopedia of Astronomy
http://www.joydiv.org/up.htm

But a plot of what?

In July 1967, astronomers at the Cavendish Laboratory in Cambridge, observed an unidentified radio signal from interstellar space, which flashed periodically every 1.33730 seconds. This object flashed with such regularity that it was accurate enough to be used as a clock and only be off by one part in a hundred million.

It was eventually determined that this was the first discovery of a pulsar CP-1919.  This is an object that has about the same mass as the Sun, but is the size of the San Francisco Bay at its widest (~20 kilometers) that is rotating so fast that its emitting a beam of light towards Earth like a strobing light house! Pulsars are neutron stars that are formed from the remnants of a massive star when it experiences stellar death.

The Wolfram Language ( Mathematica ) code to make this graphics:

R[n_] := (SeedRandom[n]; RandomReal[])

ListAnimate[Table[Show[Table[
Plot[80 - m + .2*Sin[2 Pi*R[6*m] + Sum[4*Sin[2 Pi*R[4*m] + t 
+ R[2 n * m] * 2 Pi] * Exp[ - (.3*x + 30 - 1*100*R[2 n*m])^2/20], {n, 1, 30, 1}]]
+ Sum[3(1 + R[3*n*m])*Abs[Sin[t + R[n*m]*2 Pi]]*Exp[ - (x - 1*100*R[n*m])^2/20],{n, 1, 4, 1}],
  {x, -50, 150},
   PlotStyle -> Directive[White, Thick], PlotRange -> {{-50, 150}, {0, 85}}, 
   Background -> Black, Filling -> Axis, FillingStyle -> Black, Axes -> False, 
   AspectRatio -> Full, ImageSize -> {500, 630}],
 {m, 1, 80, 1}]],
{t, 0, 6.3*18/19, 6.3/19}],
AnimationRunning -> False]

Melhor vídeo de segurança de voo de todos os tempos.
Destaque para alguns heróis do So you think you can dance como Christopher Scott e Cyrus... <3
Everyone knows I hate flying! And still I find it impressive that +Virgin America can make such a stressful experience almost enjoyable :)

No futuro, iremos decidir pela leitura de  um livro pelo tempo que iremos levar para termina-lo? 

O futuro das senhas está em uma pílula que você engole ou uma imagem tatua na pele. Uma empresa será responsável pela autenticação de você com todos os dispositivos e aplicativos do mundo. Ou você terá mais tatuagens que um yakuza.
Todo este poder com uma única empresa é tenso. Basta uma assinatura e um "obama" poderá acessar seus dados em qualquer tipo de site que colete seus dados: desde uma rede social onde você controla sua publicação até uma que coleta e analisa os dados do seu código genético. E você aí preocupado com seus dados financeiros...
