Apr 19, 2017 at 22:36 comment added Criticizing Israel not allowed Just use powers of two instead... Or if you have the room, don't, just write the 100-200 extra 0's (in base 2).
Apr 19, 2017 at 17:40 comment added Russell Borogove It's pretty trivial if they have enough math to build radio receivers. If you look at the message described in my answer, you'll see that the first page shows a mapping of unary, binary, and decimal representations of numbers; the decimals are used thereafter, telling the aliens that that's our preferred base. Page three introduces the vocabulary for exponentiation and scientific notation. Dutil & Dumas used base 10 throughout their message for two reasons: it's more compact than binary and it's easier to proofread by the message composers.
Apr 19, 2017 at 15:40 comment added called2voyage @Uwe Assuming the aliens have a similar grasp of mathematics, you could send an increasing sequence of numbers 0,1,2,3,4,5,6,7,8,9,10,11,12... to demonstrate what base is used. If the aliens don't have a similar grasp of mathematics, the chances for any meaningful communication pretty much vanish. Of course, I don't see why we would use base-10 when we could just use binary. You can see the pattern in binary a lot quicker: 0, 1, 10, 11, 100...
Apr 19, 2017 at 15:28 comment added Uwe Explaining something to another species with no common language at all is a lot more difficult than trivial.
Apr 19, 2017 at 14:52 comment added Nyny Yeah, but explaining them to another species seems trivial... But just maybe because I didn't try.
Apr 19, 2017 at 13:33 comment added user Powers of ten are only particularly meaningful because we use a decimal (base-10) system of counting. It's easy to imagine that an alien species with, say, six digits per appendage might find base-12 more natural, assuming two "hands" (which isn't a given at all!)
