Mind Hacks MakerBot Replicator impressions: the dawning of 3D printers in every home? There's something universally appealing about the concept of a 3D printer -- that concept being an automated system capable of turning computer code into real-world objects. I found myself forced to give a brief overview of the technology to AOL employees in our shared New York City office space after a particularly noisy initial run of MakerBot's Replicator. Reactions to such explanations tend to follow a fairly standard arc, beginning with wide-eyed wonder as one attempts to wrap their brain around the idea, followed almost immediately by a list of things they'd love to print out, given a chance. This is usually coupled with questions like "can it print food?" When we received an unexpected package from the folks at MakerBot last Friday, we realized it would afford us the opportunity to field some of these questions.

Pulmonary circulation is the movement of blood though the right side of the heart, to the lungs, and then back through the left side of the heart. The “lub dub” you hear when using a stethoscope is the sound of the ventricles contracting and the heart valves closing during this circulation process. Blood takes a very precise route during pulmonary circulation. Two large veins called the vena cavae bring blood to the right atrium of the heart. The atrium fills with the waste-rich blood and then contracts, pushing the blood through a one-way valve down into the right ventricle. The right ventricle fills and then contracts, pushing the blood out of the heart into the pulmonary artery, which leads to the lungs. Fresh, oxygen-rich blood enters the pulmonary veins and then returns to the heart, re-entering the organ through the left atrium.
Thinking Dispositions: Thinking Dispositions: A review of current theories, practices, and issues by Shari Tishman and Albert Andrade Introduction What does it mean to be a good thinker? In an effort to account for the affective and attitudinal dimension of high-level thinking, many scholars and educators involved in the thinking skills movement have urged attention to what are often called "thinking dispositions." There are three parts to this document. Part Two is a brainstorm of issues and questions concerning thinking dispositions that occurred in the Summer of 1994 at the 6th International Conference of Thinking, held at Massachusetts Institute of Technology, in Cambridge, Massachusetts. Part Three is a bibliography of books, articles and programs that either are directly about, or relevant to, thinking dispositions. We recognize that, although interest in thinking dispositions has increased in recent years, it is by no means a new concept. Part One: Overview of Recent Work in the Field 1. 2. 3. 4.
Arduino Drum Kit This Piezo Drum Kit from Spikenzie Labs looks like it could provide days of fun. They provide interface software that allows you to output MIDI data from your Arduino that this kit is connected to. Thanks for the tip Andy, send us some pictures when yours is built! "The kit contains the electronic parts required to make a drum kit. This includes the circuit board, resistors, diodes and pins.
