10:15 AM | Dilation Challenges

For a while now, I’ve been intrigued by the ways in which the study of geometric transformations can provide students with a very effective introduction to function concepts. Daniel and I have written a couple of articles about this topic, and we created a number of activities to take advantage of what can arguably be […]

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 […]
