Maybe the police CHIEF makes 60K/year. None of the normal police officers do. And many DA's make less than 40K/year unless they live in California or one of the other rich states.
Autocorrelation and FROG techiniques (see R Trebino's papers on the subject) are used to "measure" the pulses. You can get nice intensity vs spectrum graphs. (Why spectrum, you ask? Because you can Fourier transform it to time!)
Commercial Ti:saph lasers can get 30 fs easy. It's getting less than that that's hard.
Tmobile has the same deal. Until last August, you could even get unlimited *international* text messaging for $10/month. As someone with lots of friends in the UK who like to text message, that was great. Oh well, they still offer unlimited domestic text messaging for $10/month.

Perhaps. But that's also like just picking out the 1995-2000 year range for tech stocks. If you look at a broader range (http://en.wikipedia.org/wiki/Image:Phanerozoic_Cl imate_Change.png), you'll see that temperatures have fluctuated wildly for millienia.

A) No (large American) war in 1994 B) No (large American) election in 1994 Perhaps you meant... Heck, I have no idea what you meant.
