minus-squarearthur@lemmy.ziplinkfedilinkarrow-up1·edit-21 year agoDo you remember the Fibonacci sequence? You can use it to convert miles to kilometers . 2 mi ~= 3km 5mi ~= 8km 8mi ~= 13km 13mi ~= 21km And so on.
minus-squareDoctorWhookah@lemmy.worldlinkfedilinkarrow-up0·1 year agoWait, is this true until its not or is it true forever as you go higher in the sequence?
minus-squareabejfehr@lemm.eelinkfedilinkarrow-up1·1 year agoIt’s always true because the ratio of miles to km is really close to the golden ratio. If you do it for a zillion miles you’ll be off by a lot of km, but proportionally the same amount as for 1 mile

2 mi ~= 3km
5mi ~= 8km
8mi ~= 13km

And so on.
That’s awesome thanks !
That’s brilliant.
