Niobium to the Rescue!
I suspect everyone reading a recent ASME article was told, at least once when they were young, not to put an electrical device or live cord into water. This led to a corollary that you should not connect electrical wires under water. For those who work with electrical equipment, all underwater, this can be a […]

So Many Distractions – How to Stay Focused

Her premise for the article was “By strengthening your willpower you’ll get more done and more satisfaction in work and life.” Collaborating with Roy Baumeisster, professor of psychology at Florida State University and the University of Queensland in […]
Sports Trend – The Venue over the Game?
Sports stadiums typically started off as purely static structures, falling mostly under civil engineering. They were interesting structures, but the game being played was clearly the center of attention. However, today we have stadiums that are anything but static. Moving roofs, moving fields, moving stands, a very visible world of mechanical engineers and civil engineers […]
From Solar Waste to a Hot Opportunity
The proliferation of solar panels on roofs and in solar farms over the last 20 years is expected to create a new problem – what to do with the panels at the end of their lives? An estimated 8 million tons of waste per year is expected by 2030 and ten times that by 2050. […]

The impressive clock has three main mechanical components — the astronomical dial, the calendar dial, and an hourly display of figures and sculptures. The astronomical portion shows the position of the Sun and Moon and the calendar dial shows the months of […]
Don’t Think About Bananas!
Well, maybe we should. Apparently a very serious disease, fusarium, or banana wilt, is already affecting a fourth of the world’s banana crop. This fungus travels under the ground, so spraying from above is not an option. A very promising strategy that is being developed between the International Atomic Energy Agency (IAEA) and scientists from several […]
