    Plane on a treadmill always seems so obvious to me. Planes don’t have power connected to their wheels. Put a plane on a dynamometer and crank the engine up as fast as it will go, and the wheels will still not spin. At the same time, water planes use pontoons and are still able to take off just fine.

    The question I have is, can a plane take off with a tailwind that matches the speed that the propeller is pushing out.

    I wonder what percentage of these weird studies that make us ask “why are they spending money on that?” are being done by students working on theses and doctorates and whatnot, and what percentage are non-scholastic institutions asking for government funds to see if you can teach penguins to French kiss.


  • Cable ads aren’t the same across the country, and very soon won’t be the same across the city. Addressable TV will bring personalized ads no matter what you’re watching.

    As to why you may see a bunch of ads for similar products all of a sudden, there are a couple causes. When a new company/product comes on the market, they may flood the airwaves with ads to get their name out there, or they may not be familiar with how buying and scheduling TV ads works and will cluster things together so it seems like a barrage instead of spread out over longer periods. Also, when new competition comes to the market, the current leaders get nervous and increase advertising to retain their customers and try to keep them from changing brands. Lastly, it’s the phenomenon about noticing something which causes you to notice it even more (I.e. “there weren’t as many of [my car] on the road before I started driving one.”)
