    If we counted in base 2 rather than in base 10 we'd have celebrated the 100,000th anniversary of Kennedy's death 18 years ago

        @neiltyson Perhaps celebrated isn't the correct word here, Mr. Tyson.

        @neiltyson That'd mean we'd likely have 2 fingers. No opposable thumbs. No way to pull a trigger. Nothing to "celebrate."

        @neiltyson "anniversary" implies "annual" which implies trips around the sun. Our base counting system wouldn't change our solar lap speed.

        @neiltyson Really Neil? A year is a year is a year... i.e. One orbit of the Earth around the sun. There have only been 50 of those... #JFK50

        @RobinEdgar 100,000 is 32 notated in base 2, i.e. 1x32 + 0x16 + 0x8 + 0x4 + 0x2 + 0x1 .

        @featherglider I can see that. http://www.unitconversion.org/numbers/base-10-to-binary-conversion.html … OTOH Tyson is mixing apples with oranges by speaking of 18 years. It would be 10010...

        @RobinEdgar ..when in fact the “roundness” of a number is in a sense arbitrary, as it relies on the number notation system we use.

        @featherglider I get that, funny how a "round number" can be notated by a right angle in Roman Numerals. . . ;-) 50 = L in #RomanNumerals
