Pennsylvania State University engineers have developed a new way to simulate sonic-boom penetration into the ocean, then estimate how loud a noise the boom makes underwater, where it could annoy whales, fish, and other marine life. Called the finite difference method, the technique can compute the penetrating sonic boom noise for simple or complex ocean surfaces, corresponding to calm and rough seas. Using the technique, the researchers found that a somewhat complex wavy ocean surface only slightly augments the underwater noise from a sonic boom.
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
