The notion of a person flying like a bird has universal and enduring appeal, so it's not surprising that the "Human Bird Wings" video from "Jarno Smeets" went viral within a few days. However, now that it has been revealed to be an elaborate hoax, eight months in the making, and now that our dreams have been thusly dashed, let's examine a scientific red flag in the video, one that when pursued bursts the entire fantastical premise: the problem of speed. Watch the video: He really isn't moving very fast when he lifts up off the ground, so it doesn't look quite right. Let's analyze that.
Anyone who has ever seen The Flintstones is probably aware of the unique braking mechanism on Fred’s stone age car. I always considered the technique of dragging your feet on the ground to bring your vehicle to a stop a matter of artistic license. Until last week, when this video appeared. It provides us with an excellent real-world example where knowing a little physics might have prevented this Michigan driver with failed brakes from attempting a cross-town drive using “The Flintstone Technique”, and possibly putting himself in the running for this year's Darwin Awards.
As electronic devices increasingly permeate society, we must confront the question of how to manage the resulting e-waste of discarded cell phones, computers, iPods, and other electronic jetsam in an environmentally responsible way. Inspired by the problem, the fledgling company ecoATM has developed an innovative approach to eliminating eWaste with their prototype “ecoATM kiosk,” essentially a reverse vending machine for old cellphones. Old cellphone goes in; cash comes out.
I guess some people will do anything to get on television. In the media blitz last week, nobody seemed to pause to wonder whether the escaped helium-filled contraption would in fact have sufficient buoyancy to carry a 40-pound boy to a height of 7000 feet. Let's apply some physics to the case.
Now that looks like fun. Of course we intuitively know it's completely fake, and involves the usual videographic sleight of hand, but let's apply some basic physics to the situation to check our intuition.
Getting married in apparent weightlessness looks like fun; it's the next best thing to getting married in space.
Keep in mind that I use the terms "apparent" or "simulated" weightlessness, because, as discussed in a previous article, we're not talking about actual weightlessness in these situations. Actual weightlessness requires the absence of a gravitational force.
Last week we were treated to the unusual story of a human-versus-meteorite collision.
According to the Daily Telegraph, the youth whose hand was in the path of the pea-sized meteor saw a "ball of light." The article also made the claim that the impact with the ground left a "foot-wide crater." Both of these assertions are highly unlikely, as we shall see by simply applying some basic physics to the situation.
