ECLECTIC TECHNOLOGY ELECTRON FILMED FOR FIRST TIME WB8IMY ELECTRONS ARE THE
LIFEBLOOD OF AMATEUR RADIO.  OUR TECHNOLOGY HAS BEEN BENDING THESE LITTLE
SERVANTS TO OUR WILL FOR ABOUT A CENTURY, BUT NO ONE HAS EVER SEEN AN
ELECTRON IN ACTION UNTIL NOW.  GO TO WWW. ARRL. ORG/ FILES/ QST BINARIES/
AND DOWNLOAD ELECTRON.MPG.  THE MOVIE, CREATED BY SCIENTISTS AT SWEDENS
LUND UNIVERSITY, SHOWS HOW AN ELECTRON RIDES ON A LIGHT WAVE AFTER JUST
HAVING BEEN PULLED AWAY FROM AN ATOMS NUCLEUS.  HOW DID THEY DO IT?  THE
TRICK INVOLVED A LASER CAPABLE OF FIRING ATTOSECOND LENGTH PULSES OF LIGHT.
AN ATTOSECOND IS 10 18 SECONDS.  PUTTING THIS INTO PERSPECTIVE, IT TAKES
150 ATTOSECONDS FOR AN ELECTRON TO ORBIT THE NUCLEUS OF AN ATOM, A SPAN OF
TIME ONLY SOMEWHAT SHORTER THAN THE INTERVAL BETWEEN QRZ?  AND THE MOMENT
EVERYONE ELSE IN A DX PILEUP BEGINS TRANSMITTING.  BY FIRING THE LASER AT
THE APPROPRIATE TIMES, THE SCIENTISTS WERE ABLE TO GLIMPSE THE ENERGY
DISTRIBUTION PATTERN THAT WAS CREATED AS THE ELECTRON MOVED.  YOURE NOT
REALLY SEEING THE ELECTRON ITSELF SOME ARGUE THAT ELECTRONS DO NOT POSSESS
AN OBJECTIVE REALITY AS WE KNOW IT, BUT SOMETHING ANALOGOUS TO THE WAKE
