Earthquake Invisibility Cloak
BuzzSkyline writes "The same folks who brought us the tsunami invisibility cloak last year have now come up with an earthquake invisibility cloak. They show that a platform made of just the right configuration of elastic rings could make a structure invisible to earthquakes by effectively steering a quake around the structure. It doesn't work well for compression waves, but the researchers claim it could hide buildings from the slower-moving, more destructive shear earthquake waves. The research is due to be published soon in the journal Physical Review Letters."
If you're in marketing you call it an invisibility cloak. If you're an engineer you call it a tuned resonator and ask yourself why oh why you didn't go to medical school.

It's not an invisibility cloak. A nearby building could still fall on the cloaked one, with the usual result. Also, it's not a cloak, as in a piece of fabric. Last, anything can be made resistant to earthquakes, but to make it earthquake-proof is something only an arrogant designer or a project manager would say. Every design component can fail, and most catastrophic engineering failures are rooted in miscalculation or failing to test the model with a particular cascade of failures.

Couple of things to point out here...
A "starting" physician is 6 years behind a starting electrical engineer. 4 years of med school + 2 years of residency (at a minimum!) and they have a tremendous amount more debt for those additional years of schooling. Even at that point they are considered to have very little experience.
In addition try looking at malpractice insurance for physicians, or something called "tail insurance", ie if you leave the practice and 10 years down the road someone you treated decides to sue you the tail insurance takes care of that, but it means you're paying insurance against the chance of a lawsuit forever basically, even if you leave medicine.
Not to mention the fact that if differences were that significant in salary and the work was actually the same amount of effort or easier I have absolutely no doubt that we would see more physicians but instead of that we're actually seeing *fewer* physicians. I've often heard from physicians that anyone could do it, there's nothing special about them, just a matter of lots and lots of hard work. Most physicians I know actually recommend to their children that they *not* go in to medicine. How's that for an indication of how the field is doing?
