Kenzo Nakamura uses Mathematica to create Escher-inspired mathematical art. His trademark piece, Three-Circle Mandala, depicts a large circle covered by three smaller, repeating circles that form a Sierpinksi gasket. When Nakamura began using Mathematica, he didn’t originally intend to use it for his artistic endeavors. He found the program by chance at a seminar while [...]

Finding infrequent errors in MATLAB with DBSTOP if error Some errors happen in MATLAB infrequently. If you don’t know the conditions when they occur, setting a breakpoint might not work. Using DBSTOP if error will have MATLAB stop on a line in the editor only when the error condition is tripped.

5:07 PM | Demographic Anomalies: US Edition

It’s been a while since we looked at American Community Survey data in Wolfram|Alpha. Our first efforts included surveying ACS data related to education, income, and diversity, only touching the tip of the iceberg. Recently, we took a deeper look at the data to unearth some of the least “average” communities in the US. As [...]

For as long as I can remember, my all-time favorite activity has been creating ideas and turning them into reality—a kind of “entrepreneurism of ideas”. And over the years—in science, technology and business—I think I’ve developed some pretty good tools and strategies for doing this, that I’ve increasingly realized would be good for a lot [...]

11:54 AM | Archimedische Körper konstruieren

Die archimedischen Körper sind eine Klasse von 13 geometrischen Körpern mit gemeinsamen Eigenschaften. Sie haben besondere Symmetrieeigenschaften und werden daher auch semi-regulär genannt.Alle archimedischen Körper kann man aus den platonischen Körpern konstruieren. Und wie genau das funktioniert, zeigen wir hier.

12:05 PM | What Do Teachers Think About EdTech ?

We know there are a lot of teachers out there using technology in their classrooms. We also know there are a lot of teachers who aren’t – whether they can’t due to financial constraints or just flat out don’t want to (or some combination thereof). We interact with a ton of teachers on social media […]

As summer heats up, we instinctively reach for the air conditioning (AC) controls. This miracle of modern technology lets us create a cool breeze to banish the crushing heat. At the same time, AC brings soaring electric bills. How can we optimize our use of air conditioning, keeping cool while minimizing our costs? Wolfram|Alpha provides [...]

**Guest Post by Tim Bond** Converting between two unit systems or converting within a single unit system is expected to be done flawlessly. The reality is, mistakes happen. Common conversions like inches (in) to centimeters (cm), or miles (mi) to feet (ft) may be memorized, but the conversion factor between pound force per square inch (psi) and Pascals (Pa) is ...

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.
