How Things Work: Highway Barriers
You have somewhere to go. You jump in the car and maneuver onto the nearest interstate. Whatever your destination, the National Highway System has probably helped you get there at some point. These highways allow direct, fast, and safe movement across the country; however, the high level of safety we have today on our highway systems hasn?t come easily.
When designing highways, minimizing the sev...SciTech | September 19, 2005
How Things Work: radioisotope thermoelectric generators
When you imagine a deep-space probe, what do you see? A big metal box, a forest of antennas, and a pair of solar panels, right? Wrong.

Before you inundate yourself in ?real? knowledge, why not take a moment and reflect on a very special part of Carnival? No, not the beer ? booths! Coincidentally, this year?s Carnival theme happens to be exactly the one we in the SciTech section are best at explaining: How Things Work.SciTech | April 18, 2005
How Things Work: Submarines
As the ?How Things Work? columnist, I am obliged to ensure that my readers get the truth. When an egregious falsehood enters into mainstream thought, I must take immediate action. Therefore, I feel ashamed to admit that my readership has been misinformed on a very important subject ever since January 13, 1969.
The untruths that began to spread on this fateful day have even corrupted Carnival 2005...SciTech | April 18, 2005
