Private Universe Project in Mathematics: Workshop 4: Thinking Like a Mathematician
What does a mathematician do? What does it mean to think like a mathematician? This program parallels what a mathematician does in real life with the creative thinking of students.,How a Mathematician Approaches Problems - Fern Hunt, a mathematician at the National Institute for Standards and Technology, is seen as she collaborates with colleagues to solve difficult technical problems. Using the metaphor of the children’s game Towers of Hanoi, she explains her approach to solving problems. 15 m

Chemical Equilibrium in the Gas Phase
This website describes gas phase equilibrium chemistry and provides a tutorial on key concepts like LeChatelier's principal and includes on-line exercises in which the reader can check their understanding. Calculations of equilibrium constants expressed in terms of pressure and concentration are presented. This site will be most useful for high school and introductory university Chemistry courses in which students are developing an understanding of equilibrium chemistry.

Six days a week, a new math problem is posted on this Web site to intrigue and challenge grade school students. Each Daily Brain has a different theme, considering some mathematical perspective of science, history, geography, and more. After solving the problem, or for a little help, students can look at a step-by-step solution that is also posted online. All old Daily Brains are kept in an archive, and as of May 2003, they numbered around 400. The problems are mostly intended for students betwe

Located at the University of Wales, the Centre for the Popularisation of Mathematics brings a more artistic side to the often plainly presented subject. Several online exhibits and galleries illustrate sculptures and knots that have a basis in math. One of the most interesting and famous mathematical sculptures is the Mobius Band. The centre gives a description of the Mobius Band and its significance, as well as instructions on how to create one and interesting experiments to try. Many other scu

M.C. Escher is a widely known and popular artist whose work depicts complex, and often impossible, geometrical patterns. This Web site examines the mathematics behind his drawings. Many examples of Escher's work are given, illustrating mathematical principles such as the shape and the logic of space. Tessellations and polyhedra are common building blocks of the drawings. It is quite interesting to see how basic designs are transformed into the intricacies depicted by Escher. The material is cert

Approximating pi
This web page features mathematical information about Archimedes' successful approach to finding an approximation to pi and an interactive manipulative that replicates the approach. The user can approximate pi as a number between the lengths of the perimeters of two polygons, one inscribed inside a circle and one circumscribed around the circle. The number of sides for the polygons may be increased to 96 with the value for pi always being between the two approximations. Similarities and differen

Deviation between the sliding direction of the chip over the tool and the direction of the friction
Pure oblique cutting experiments with conventional cutting tools as well as ultra-sharp tools have been carried out under a wide range of cutting conditions using a linear slide based cutting set-up. The chip flow direction was measured using the 3D Digital Image Correlation (DIC) technique of high-speed stereoscopic images and the frictional force direction was determined from forces. It is estimated that the error in chip flow angle measurements using DIC, was approximately ±1°, as was the e

Building a testbed for mini quadrotor unmanned aerial vehicle with protective shroud
Potential applications of small rotorcraft unmanned aerial vehicles (UAVs) range from military missions to exploration of the planet Mars (Patrick C. O’Brien, 2003). Tasks such as exploration of unknown territories, formation flying, intelligence gathering etc, require UAV to be capable of flying very close to other flying or steady objects. Exposed rotary wings limit rotorcraft vehicle’s capability to fly in proximity of other objects. In some applications, such as rescue operation, urban w

Looking at Learning ... Again, Part 2: Workshop 2. Mathematics: A Community Focus
With Dr. Marta Civil. As teachers, we often make assumptions about the knowledge children are exposed to at home. Sometimes it seems that we focus on only reading and writing,Dr. Civil contends that we need to look more carefully at the mathematical potential of the home and that it is essential that schools learn to be more flexible and knowledgeable about students’ home environments.
