"Professor Goddard does not know the relation between action and reaction and the need to have something better than a vacuum against which to react. He seems to lack the basic knowledge ladled out daily in high schools."
--1921 New York Times editorial about Robert Goddard's revolutionary rocket work.

"Correction: It is now definitely established that a rocket can function in a vacuum. The 'Times' regrets the error."
NY Times, July 1969.

Comet Boattini

C/2007 W1 (Boattini):  

Keep an eye on this comet - it may reach 6th magnitude or better during early evening hours in late May before it gets too close to the Sun. See: http://cfa-www.harvard.edu/iau/Ephemerides/Comets/2007W1.html 

Looks like it'll actually get quite close to Earth but unfortuantely will be in the daytime sky at that point and so not viewable. :-(
