I suspect the assistant professor said to light the fuse on both ends and in the middle, however this wouldn't work since the fuse burns unevenly.

Turn another switch on and leave it on. Go check the bulb. If its on its the second switch, if its off and hot its the first and if its off and cold its the third.

Hour hand is 1 quarter of the way between 3 and 4. So the question breaks-down to how many degrees is 1 quarter of the distance between a single hour. There are 360 degrees on the clock. Divide 360 degrees by 12 hours, which gives you 20 degrees Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6157718941667184695.post-46769961161729401872008-09-18T03:53:00.000-07:002008-09-18T03:53:00.000-07:00foo said...now, a couple of years ago, an assistan...<EM><B>foo said...</B><BR>now, a couple of years ago, an assistant professor in mathematical analysis after 10 min think gave me an answer for the 15 second version, using only one fuse. :)</EM><BR/><BR/>Hi ;) - Please share this solution..Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6157718941667184695.post-80511918232898700262008-08-20T12:06:00.000-07:002008-08-20T12:06:00.000-07:00i know n.4 with 15 seconds, which is generally the...i know n.4 with 15 seconds, which is generally the same problem.<BR/><BR/>now, a couple of years ago, an assistant professor in mathematical analysis after 10 min think gave me an answer for the 15 second version, using only one fuse. :)Anonymousnoreply@blogger.com
