We have all been caught in a traffic jam with no actual cause. One minute, you’re cruising along at road speed, and the next minute you’re hissing and spitting at the windshield because the moron in front of you has stopped. Usually it’s not that moron’s fault, because someone stopped before him. The theory behind this sort of traffic congestion is called a shockwave traffic jam, and until recently, it has only been studied in computer simulations, not real life experiments. But now, the Japanese have replicated this daily phenomenon in the laboratory setting.

The only issue I have with this whole study is why it took so long to replicate, or possibly why someone actually bothered to do it. I mean, honestly, it seems like a huge waste of time to bother doing this in a controlled lab setting when anybody who has ever driven in any major city could have told you how it happens (morons slow down for no good reason) and why it happens (morons who can’t drive are allowed to drive). Write me a check, I just explained traffic jams!

Explaining how something happens, and why it happens, is not as important as stopping it, at least in this case. Who cares about the why? All I want to know is how do urban planners keep it from happening, so I don’t curse and snarl through yet another drive to/from work. It’s not good for my blood pressure.

Margaret O’Callaghan had a need for a new type of kitchen utensil.  The round-bottomed ladle and the spatula are just not good enough when you’re dealing with things like crock pots and serving dishes.  That’s why she invented the scrudle, a combination ladle and spatula designed to scrape the deliciousness from any sort of cooking […]

Every day, Tom Baker deals with the issue of traffic.  Given Southern California’s massive concentration of cars, it’s no wonder that Baker would get frustrated dealing with the daily traffic routine.  That inspiration resulted in these great images of Los Angeles without the cars.   Here’s the full image gallery, and it’s awesome.
I love the […]

Have you ever wondered where salt comes from?  I mean, salt is in everything from fertilizers (potassium chloride) to the dinner table (sodium chloride), but where does it actually come from?  Why, salt mines, of course!  They’re not just for horrible industrial accidents or mad scientist lairs anymore.  English Russia has a great look inside […]

For some reason, the kids these days love the Twilight saga.  Believe me, it pains me to call it the Twilight saga, because to me a saga is a great, sweeping work of masterful literature, not a teenage vampire romance novel.  Either way, the latest movie based on the Twilight books, New Moon (officially The […]

People worry about all kinds of crises as the world ends, but as the movie Zombieland taught us, sometimes it’s our snack foods that are most important to our happiness.  For Tallahassee, it was his beloved Hostess Twinkies.  If your favorite food is the humble Eggo waffle from General Mills, then you’d best head to […]

I love goofy little websites like this.  From the Wal-Martians to quality engineering, I love a nice, odd corner of the Internet to investigate.  If it’s something that can result in some comedy thanks to random word generation, even better.   That’s why when Mysterio offered to predict my holiday gifts, I jumped at the […]

Linguist d’Armond Speers is an odd bird.  How else could you explain someone that taught his son Klingon as his first language? For the first three years of his son’s life, Speers spoke to his son only in the fictional alien language Klingon from the Star Trek universe.  His reasoning?  It was an experiment to […]
