Ka'idar Dangantakar Galileo matsayin kafuwar Einstein ta ka'idar dangantakar

Gabatar a kotu na kimiyya al'umma a farkon karni na karshe, ka'idar dangantakar halitta a furor. Its marubucin, Albert Einstein, shekaru da dama a tsare a cikin babban kwatance na jiki bincike. Amma kar ka manta da cewa wani Bajamushe masanin kimiyya a cikin aikinsa amfani da yawa nasarorin da suke a gabãninsu, ciki har da sanannen Bagalile manufa na Dangantakar - sanannen Italian masanin kimiyya.

A gagarumin bangare na rayuwa, da Italiyanci kimiyyar kishin nazarin makanikai, zama daya daga cikin wadanda suka kafa wannan reshe na kimiyyar lissafi, a matsayin kinematics. Galileo ta gwaje-gwajen a yarda da shi ya zo ga ƙarshe cewa muhimman hakkokin bambance-bambance a Jihar sauran kuma uniform motsi ba - abu ne, abin da reference batu ne soma. Shahararren likita, ya nuna cewa dokokin da makanikai ne inganci ba ga wani daya zaba daidaita tsarin, da kuma ga dukan tsarin. Wannan manufa ta sanya tarihi a matsayin Bagalile manufa na Dangantakar, da kuma tsarin zama da aka sani a matsayin inertial.

Ya msar tambayar lissafin masanin kimiyya tare da yardar aka tabbatar da misalai da yawa daga rai. A mafi m misali na littafin, wanda shi ne a kan jirgin cikin jirgin, wanda idan da shi ne dangi zuwa ga jirgin kadai, da kuma game da wani mai tsaro a kan tudu, yana motsi. Galileo ta qa'ida tabbatar da matsayinta cewa zaman lafiya tsakanin motsi da kuma babu wani bambanci.

Tsara a cikin wannan hanya da manufa na Bagalile dangantakar sanya daga Sahaban halitta a furor. The abu ne cewa, kafin littafin na ayyukan Italian masana kimiyya sun duk tabbata daga cikin gaskiyar da koyarwar da tsoho Greek masanin kimiyya Talomi, wanda da'awar cewa Duniya tana da cikakken m jiki tare da girmamawa ga wanda akwai wani motsi da sauran lokuta. Galileo halakar da wannan ra'ayi, bude sabon sãsanni ga kimiyya.

A daidai wannan lokaci, za mu iya ba a kowace hanya kuma zuwa idealize Bagalile dangantakar manufa ko dokar inertia. Bayan duk, a kan tushen da wannan wording, shi za a iya ƙarasa da cewa duk wadannan kayan abinci ne da cikakken ga wani sigogi na gudu da kuma nesa tsakanin jikinsu, amma shi ba. A mataki na farko na Galileo-Newton koyarwar ka'idar dangantakar da aka ci gaban Gauss, Gerber da Weber ta msar tambayar tushe na sabon abu, wanda aka kira "retarded m."

Babu Galileo kuma Newton cikin karfi wanzu a matakin na ilimi da lokacin da zai iya ba ko da tunanin cewa m gudun jiki zuwa gudun haske dokokin inertia kawai gushe aiki. Kuma, a general, Bagalile dangantakar manufa shi ne manufa kawai ga wadanda tsarin, wanda ya kunshi biyu jikinsu, watau rinjayar sauran abubuwa da kuma mamaki a kan su ne don haka kananan kamar yadda ya zama negligible. Movement a cikin irin wannan tsarin (misali da Duniya ta juyawa a kusa da rãnã) zai daga baya za a kira da cikakkar, duk sauran ƙungiyoyi ake kira zumunta.
