| I am not sure I understand. Sin(x) approaches x only when x approaches 0. When else does the universe does a bad job with this approximation? |

| the joke is that sometimes the universe is bad at making sure x always approaches 0. |

| sin(x)=x in the same way that c=π=1 when doing cosmology. |

| ▲ | mr_mitm 7 days ago | parent [-] | | 1=c=G=hbar and sometimes =k is not even a joke, that's just natural units. Pi=e=1 however ... is only half a joke, because cosmologists are often only interested in orders of magnitudes, and even those are sometimes approximated. |
