Rube Goldberg and the Meaning of Machines
Simple and compound machines are designed to make work easier. When we encounter a machine that does not fit this understanding, the so-called machine seems absurd. In this lesson, the cartoons of Rube Goldberg are introduced and engage the students in critical thinking about the way his inventions make a simple task even harder to complete. As the final lesson in the simple machines unit, the study of Rube Goldberg machines can help students evaluate the importance and usefulness of the many ma

2.3.4 Lateralisation

It has long been suspected that unusual patterns of cerebral lateralisation (i.e. the ‘division of labour’ between left and right hemispheres of the brain) may have some connection with dyslexia. Early researchers noticed an apparent excess of left-handedness in children with specific reading difficulties (and their relatives). However, most dyslexic people are in fact right-handed, and most left-handed people are not dyslexic. Nonetheless, large-scale analyses of the research

2.2.3 ‘Automaticity’ and ‘rate of processing’ hypotheses

A proposal that attempts to address the broader picture of dyslexic functioning is that dyslexia may be caused by problems in the automatisation of skills. The concept of automatisation refers to the gradual reduction in the need for conscious control as a new skill is learned. This leads to greater speed and efficiency and a decreased likelihood of breakdown of performance under stress, as well as the ability to perform a second task at the same time with minimal disruption to

1.7.2 Differentiating within dyslexia – acquired versus developmental dyslexia and the search

There has also been continued debate regarding the variability within any dyslexic population, the apparent variety of forms that dyslexia can take. Given the complexity of the skills required to develop fluent reading and spelling perhaps this is not surprising. The variability within dyslexia may simply reflect the fact that this complex process can go wrong in different ways and for different reasons.

The term ‘dyslexia’ was originally used to refer to the acquired

Great Zoom out of New York, NY: Central Park
Using data from different spacecraft and some powerful computer technology, visualizers at the Goddard Space Flight Center present you with a collection of American cities in a way you have never seen them before. Starting with our camera high above the Earth, we rush in towards the surface at what would be an impossible speed for any known vehicle. Passing though layers of atmosphere, the colors of our destinations shimmer with their own unique characteristics, and suddenly we find ourselves fl

NeuroLogic Exam: Introduction: "x" Values
So far we have a handle on the vertical localization within the neuroaxis but we have a very flat, one-dimensional structure. We need to have a way to come up with "x" values. Let's rotate the neuroaxis by 90 degrees so we can see it in the coronal plane. Now we can appreciate that most structures in the neuroaxis have a right, left or midline orientation on our "x" axis. The first principle of neurologic diagnosis is regional or anatomical localization. In order to become skillful the student m

Modern proteomes contain putative imprints of ancient shifts in trace metal geochemistry
Because of the rise in atmospheric oxygen 2.3 billion years ago (Gya) and the subsequent changes in oceanic redox state over the last 2.3–1 Gya, trace metal bioavailability in marine environments has changed dramatically. Although theorized to have influenced the biological usage of metals leaving discernable genomic signals, a thorough and quantitative test of this hypothesis has been lacking.
