Over the last 150,000 years the world’s climate has switched constantly from warm interglacial to cold glacial conditions, marked by advances and retreats of ice sheets. From 75 – 60,000 years ago the climate was glacial and cold. The huge volume of water locked up in the ice caps of northern Europe and North America t...
Teachers who are developing students’ capacity to "attend to precision" focus on clarity and accuracy of process and outcome in problem solving. A middle childhood teacher might engage his students in a "number talk" in which students use an in/out table and a plotted graph to "guess [the teacher’s] number." An early a...
A Checksum is used for error checking while transferring a file. We know that data flows across the network in the form of packets. So, checksum is a computed value that is dependent on the contents of a file. For each packet the computed checksum will be different. This computed value is transmitted with the packet wh...

"We said, Hang on," Bamford explained. "People are small. We only need to make a little hole in the solar wind." To test the idea, her team borrowed laboratory equipment used for work in fusion power, a process that also involves magnets. The scientists placed a small magnetized object—a simulated "spaceship"—into a fl...
Torque is the application of force where there is rotational motion. The most obvious example of torque in action is the operation of a crescent wrench loosening a lug nut, and a close second is a playground seesaw. But torque is also crucial to the operation of gyroscopes for navigation, and of various motors, both in...

Orbital velocity, velocity sufficient to cause a natural or artificial satellite to remain in orbit. Inertia of the moving body tends to make it move on in a straight line, while gravitational force tends to pull it down. The orbital path, elliptical or circular, thus represents a balance between gravity and inertia. A...
It's a common belief that hearing-impaired people just can't hear sounds loudly enough, but it's more complicated than that. The four main problems caused by hearing loss are: Hearing tests measure what sounds you can and can't hear. Our clinicians can use a variety of tests to find out about hearing. They will plot yo...
