The Big Bang Theory — a television show that features four male scientists and engineers and an attractive blond waitress — is one of the top shows on TV. But a recent study has raised an interesting question: Does this show’s — and others like it's — depiction of what scientists and engineers look like actively discourage women from pursuing STEM degrees? According to the study, it might.
I've spent a fair amount of time researching and writing about the centroid file and about CAD library footprints. One of the challenges in this industry is that somethings that are "standard" really aren't all that standard. That's why we...
Do red-light traffic cameras reduce accidents? Save lives? Are they a boon to resource-strapped law enforcement agencies? A boondoggle? An invasion of privacy? With government surveillance – and the citizenry’s awareness thereof – at a fever pitch, this issue will only become more relevant ... and divisive.
In the early days of white-emitting LEDs, the available chip packaging materials were ones developed decades earlier for use with red- and green-emitting devices. Unfortunately, when using those materials for blue-based white LEDs (blue LED + phosphors), unexpected problems arose.
Standard incandescent lamps convert almost all the power they consume into radiation (basically, heat). Unfortunately, only about 5% of this emission is in the visible spectrum, making them very inefficient light sources. On the other hand, since almost all the power is radiated away, there is little need for thermal management.
I’m standing in the taxi queue at Chicago’s O’Hare airport, having to squint ahead to gauge my wait. The cause of my discomfort: a horrible, blue-LED array-based outdoor luminaire ahead of me and above, spilling light in all directions and casting a putrid smear of yellow-green color against a nearby wall of the terminal, and directly into my eyes.
When it comes to the racing world, electronics suppliers and distributors are often behind the scenes—or under the hood, as it were—rock stars. Sure, they’re the reason the engine runs or making sure the driver and crew are safe, but they’re very rarely front and center in the racing world. Unless, of course, you’re talking about Mouser’s sponsorship of Indy car driver Tony Kanaan ... then it’s all about being in front (literally.)
I am a fan of not sending soldiers into battle, but I understand that wars still need to be fought (sometimes). Drones are a solution to that conundrum, firepower without the high risk for lives (on our side at least). Putting any ethics aside about drones killing civilians and the lack of a weight of responsibility...
House fires are a serious, deadly problem. Death from fires and burns are the third leading cause of fatal home injury, according to the CDC. Every 169 minutes, someone dies in a fire and every 30 minutes, someone is injured.
If we want our opinions to be easily influenced by something, watching movies is the solution. Movies are a form of art that is globally used for entertainment purposes. Science fiction films that exhibit unusual and odd actions and gadgets are the ones doing big businesses on the box office.
Much like a hockey team, an electronic system is the sum of its parts, and that’s never as true as when one of those parts needs to be replaced but can’t be found. Faced with an obsolete or hard-to-find component, the end-user can invest in
I have been in the LED business for almost twenty years, and each year I hear a comment along the lines of “LEDs are a commodity product”. What’s the definition of a commodity product? It’s one that is very cheap, undifferentiated, anybody can make it, and margins are low.
A few weeks ago I mentioned that an eminently qualified historian of technology has written a biography of Nikola Tesla (1856-1943), the inventor of the eponymous Tesla coil, the induction motor, and numerous other ingenious contraptions. While Tesla has been the subject of numerous popular biographies and even a film or two...
“Ten bucks for a light bulb?!”, exclaims my daughter in response to my estimate of the ‘tipping point’ price for LED-based lighting products for the residential consumer. She, like many consumers, has yet to internalize that the real cost of ‘inexpensive’ conventional light bulbs is energy consumption, and that LEDs pay back on this aspect right away.
Any time a new, disruptive technology enters the public sphere, concern is raised about almost every conceivable aspect. This is especially the case for lighting wherein each and every one of us has a base of experience and, likely, some opinions. While it is certainly prudent to scrutinize any new technology from a health and use perspective...
