Host: What Has Driven Women out of Computer Science? — What’s particularly puzzling is that the explanations for under-representation of women that were assembled back in 1991 applied to all technical fields. Yet women have achieved broad parity with men in almost every other technical pursuit. When all science and engineering fields are considered, the percentage of bachelor’s degree recipients who are women has improved to 51 percent in 2004-5 from…

Host: Technology Billionaire Offers Advice — “The most important thing he’s got to do is kick-start a huge amount of research and innovation in energy,” said Mr. Doerr, who backed Google and Amazon.com and has invested heavily in clean technology for the last few years. How to do that? Double the number of engineers who graduate from American universities each year to 60,000, Mr. Doerr said. Bring more women into the field, and encourage…

Host: Introduction to measurement theory — When using any type of measurement system, it is important to understand whether it is possible in theory to obtain the result you need. This entails a knowledge of the principles of operation and the affect that environmental factors can have on the outcome. For example, a x wire probe has an acceptance angle limit of approximately 90 degrees. If the flow goes outside the acceptance angle, the…

Host: Laser velocimetry calibration — Did you know that you can obtain laser velocimetry equipment calibrated to traceable standards?As a matter of fact, some US government organizations use Dantec laser velocimeters to calibrate their windtunnels. Why? Because this equipment is a reliable indicator of velocity not subject to influences of temperature, pressure, it doesn't drift and is constant as the wavelength of light. A…
