BBC To Air First Televised Sperm Race
weekendwarrior1980 writes "BBC 3, a digital TV channel in the UK, is televising a race involving the sperm of presenters Dr Mike Leahy and Zeron Gibson. The sperm race will be part of the educational Lab Rats series. Gibson is a comedian and Leahy is a scientist. The network considers this a 'creative risk' but wants to reach out to an audience that avoids educational shows. The show will be broadcasted on April 15th at 2330 BST. Future shows will examine sleep deprivation and centrifugal force."
Where do we draw the line?
i really hope they mean centripetal force...otherwise there wont be much educating goin on.
You know, somewhere, someone is taking bets on this...

The sperm race may be a gimmick, but it doesn't preclude educational content. There are lots of educational things you can put into a program centered around a sperm race. Also, it isn't necessarily stupid -- the characteristics that make sperm win races are almost certainly related to the probability of sucessful conception.
If an educational program loses its audience, it ceases to educate.
To set the record straight: A "centripetal" force is any force that causes an object to move in a circular path. When swinging something on a rope, the centripetal force is the tension in the rope. With orbiting planets, the centripetal force is gravity.
"Centrifugal force" is a fictional force invented to allow one to use Newton's laws in a rotating frame of reference (they only work properly in inertial frames, i.e. those which are neither accelerating nor rotating). It is NOT a reaction to a centripetal force - the object in question doesn't have to be moving in a circle. Let me clarify this: Say you're sitting on a merry-go-round cross-bred with an air hockey table. If you drop a puck on the (nearly frictionless) surface, what happens next depends on how fast the table is rotating. If it's not rotating, the puck sits there - the table is an inertial frame of reference in this case, so Newton's laws work without modification. If it is rotating, you'll see the puck slide toward the edge in a curved path. Somebody standing on the ground next to the table sees the puck slide in a straight line, as one would expect. But since you're sitting in a rotating reference frame, and you really like Newton's laws, you have to invent a reason to explain why the puck slides away. If you're a historically accurate dumbass, you'll call it centrifugal force.
There's actually no force involved (it's just inertia viewed from a screwed-up reference frame), so it's preferable to call it 'centrifugal acceleration.' Since acceleration is always frame-dependent, while forces supposed to be frame-independent, this term leads to somewhat less confusion and similarly fewer ignorant slashdot posts. Similar logic applies to the Coriolis effect (which the guy sitting on the table says is the reason the puck's path curves).
Bugrit! Millenium hand and shrimp!
They've never seen the movie "Look who's talking"
