A Multi-Function Clip That Hides a Toolbox In Your Hair
Andrew Liszewski
A Leatherman multi-tool hanging off your belt is a great way to stay prepared for emergencies, but it means you look like someone with a Leatherman hanging off their belt—and that part’s not so great. This innocuous hair clip is a better alternative. It manages to replicate the functionality of quite a few tools, but will all but disappear when used to keep your bangs

Here is a fun interactive display by Noah Velltman of the height and weight of National Football League players from 1920 to 2014, via Statistical Modeling... Clicking on this link allows you to vary the year and observe the joint distribution of height and weight over the years. You can even see how the game as changed from the early 1990s as roles and players have become more specialized resulting in distinct clusters of body types.

Fibonacci you crazy bastard….
As seen in the solar system (by no ridiculous coincidence), Earth orbits the Sun 8 times in the same period that Venus orbits the Sun 13 times! Drawing a line between Earth & Venus every week results in a spectacular FIVE side symmetry!!
Lets bring up those Fibonacci numbers again: 1, 1, 2, 3, 5, 8, 13, 21, 34..
So if we imagine planets with Fibonacci orbits, do they create Fibonacci symmetries?!

via @CERN http://t.co/9Rac42mBVh #CPviolation #CPsymmetry #matter #antimatter The CP violation is a violation of the CP-symmetry, a combination between the charge conjugation symmetry (C) and the parity symmetry (P). CP-symmetry states that the laws of physics should be the same if a particle is interchanged with its antiparticle, and then its spatial coordinates are inverted.The CP violation is discovered in 1964 by Christenson, Cronin, Fitch, and Turlay (Cronin and Fitch awarded the Nobel […]

by @ulaulaman http://t.co/Q3AODpvKAs #Godel #ontologicalproof #god #computer The ontological arguments for the existence of God was introduced for the first time by St. Anselm in 1078: God, by definition, is that for which no greater can be conceived. God exists in the understanding. If God exists in the understanding, we could imagine Him to be greater by existing in reality. Therefore, God must exist.There are a lot of phylosophies, mathematics and logicians that proposed their ontological […]

La settimana scorsa, su twitter, ho diffuso alcune immagini, foto scattate dalle pagine dal volume Letture da Le Scienze: Fisica delle particelle (un indice del volume), che raccoglieva alcuni articoli usciti sulla rivista italiana (e quindi anche su Scientific American). Poiché ognuna di quelle immagini fa inevitabilmente parte della storia della fisica, mi sembra sensato proporle raccolte insieme in un unico post molto più semplicemente raggiungibile di tanti piccoli... cinguettii.
