Jist\u011b, i ten, kdo kompas nem\u011bl, si mohl n\u011bjak poradit. Mohl pozorovat slunce, hv\u011bzdy nebo li\u0161ejn\u00edk na stromech \u010di kamenech, ale p\u0159ece jenom byl kompas n\u011bco lep\u0161\u00edho, navzdory sv\u00e9 jednoduchosti technicky dokonalej\u0161\u00edho a v\u017edy funk\u010dn\u00edho.Prvn\u00edmi kompasy se mohli pochlubit u\u017e ve starov\u011bk\u00e9 \u010c\u00edn\u011b. Tehdy \u0161lo ale logicky jen o jednoduch\u00e1 za\u0159\u00edzen\u00ed, sest\u00e1vaj\u00edc\u00ed z d\u0159ev\u011bn\u00e9 podlo\u017eky s kusem magnetovce, je\u017e byla vlo\u017eena do n\u00e1doby s vodou.

Gyroskop slou\u017eil pro blaho lid\u00ed stejn\u011b jako pro prav\u00fd opak. Poslou\u017eil t\u0159eba v prvn\u00edm ponorkov\u00e9m torp\u00e9du, je\u017e udr\u017eoval v p\u0159\u00edmo\u010dar\u00e9m pohybu, podobn\u00e1 za\u0159\u00edzen\u00ed jsou ale d\u016fle\u017eit\u00e1 i pro pohyb sol\u00e1rn\u00edch panel\u016f n\u00e1m dob\u0159e zn\u00e1m\u00e9 vesm\u00edrn\u00e9 stanice ISS.

S t\u011bmi primitivn\u00edmi za starov\u011bk\u00e9 \u010c\u00edny bychom toti\u017e logicky u\u017e d\u00e1vno neusp\u011bli. By\u0165 ani ty logicky nezmizely v propadli\u0161ti d\u011bjin.

V\u017edy\u0165 sta\u010d\u00ed jenom naplnit n\u00e1dobku vodou, na ni um\u00edstit korkov\u00e9 kole\u010dko se zmagnetizovanou jehlou a je to. Navzdory sv\u00e9 primitivnosti to funguje dodnes a spolehliv\u011b n\u00e1m to uk\u00e1\u017ee, kde je sever.A je tak mo\u017en\u00e1 \u0161koda, \u017ee v na\u0161\u00ed vl\u00e1d\u011b asi takov\u00fd kompas nem\u00e1me.
