Zosangalatsa za sayansi. Physics otizungulira: chidwi mfundo

Kodi sayansi wolemera mfundo zosangalatsa? Physics! Kalasi 7 - ndi nthawi pamene ophunzira anayamba kuliphunzira. Kwa akuluakulu nkhani kanthu sanali kuoneka yosasangalatsa, timapereka kwa kuyamba kuphunzira mfundo zosangalatsa.

N'chifukwa chiyani asanu mitundu utawaleza

Zosangalatsa za sayansi akhoza ngakhale kukhudza utawaleza! Chiwerengero cha mitundu mmenemo kumatanthauza Isaak Nyuton. The chodabwitsa cha utawaleza, chidwi kwambiri Aristotle, ndi Persian katswiri zomwenso chinatseguka kumbuyo m'zaka za m'ma 13-14. Komabe, ife Tikutsatira za utawaleza, kuti Newton anachita mu "Optics" mu 1704. Iye anafotokoza mtundu ntchito prism galasi.

Ngati inu kuyang'anitsitsa pa utawaleza, inu mukhoza kuwona momwe mitundu kuyenderera bwino mu wina ndi mzake, kupanga chiwerengero chachikulu cha mitundu. Ndipo Newton poyamba allocated isanu yokha yakuti: wofiirira, ulusi, zobiriwira, wachikasu, wofiira. Koma wasayansi anali kumulakalaka manambala, choncho ankafuna kuti anthu ambiri a mitundu chithunzi lachinsinsi "zisanu ndi ziwiri". Iye anawonjezera kuti malongosoledwe a utawaleza ukadali mitundu iwiri - lalanje ndi buluu. Kotero ine kupeza utawaleza seveni wachikuda.

madzi mawonekedwe

Physics - otizungulira. Chidwi mfundo akhoza kudabwa, ngakhale pankhani zinthu ozoloŵereka monga madzi wamba. Ndife tonse amakonda kuganiza kuti madzimadzi alibe nazo mawonekedwe, akuti ngakhale sukulu buku pa sayansi! Komabe, siziri choncho. Natural madzi mawonekedwe - mpira.

Kutalika kwa Tower Eiffel

ndi kutalika yeniyeni ya Tower Eiffel chiyani? Ndipo izo zimatengera nyengo! chakuti kutalika la nsanjayo zimasiyanasiyana ndi mochuluka momwe 12 masentimita. Ichi chimabwera chifukwa chakuti nthawi yotentha, dzuwa mkangano nyumba, ndi matabwa kutentha akhoza kufika madigiri 40 Celsius. Ndipo monga amadziwika, zinthu zikhoza kukodzedwa pansi kutentha.

asayansi odzipereka

Zosangalatsa za sayansi silingakhoze kokha zosangalatsa, komanso kulankhula za kudzipereka kwawo ndi kudzipereka kwa utakhala amakonda. Pa kafukufuku wa magetsi Arc sayansi Vasily Petrov kuchotsedwa wosanjikiza pamwamba pa khungu pa mosavuta kuona mafunde ofooka.

Ndipo Isaak Nyuton koyamba maso yake kafukufuku kuti timvetsetsetse chikhalidwe cha masomphenya. Asayansi akukhulupirira kuti tikuona chifukwa kuthamanga kuwala pa diso.

mchenga wotitimira

Zosangalatsa za sayansi kungathandize kumvetsa katundu zimenezi ndimasewera ngati mchenga wotitimira. Iwo sanali Newtonian madzimadzi. munthu kapena nyama A sangathe kuyenda pansi pa madzi mu mchenga wotitimira kwathunthu chifukwa kukhuthala mkulu, komanso kutuluka zovuta. Kuti phazi lako la mchenga wotitimira, muyenera kuchita khama kuti zikufanana ndi kuukitsidwa kwa galimoto.

N'zosatheka adzawonongedwa, koma kuopsa kwa moyo ndi madzi m'thupi, dzuwa, mafunde. Pamene jekeseni mchenga wotitimira ayenera chagada ndi kuyembekezera thandizo.

hypersonic liwiro

Inu mukudziwa, chimene chinali chipangizo choyamba kuswa phokoso chotchinga? Wamba m'busa chikwapu. Dinani ng'ombe mantha, palibe kanthu ngati thonje kugonjetsa liwiro phokoso! Iwo amapunthwa nsonga ya chimachititsanso chikwapu mofulumira kuti amalenga yoweyula mantha mu mlengalenga. Chinthu chomwecho chimachitika ndi ndege zouluka imathamanga supersonic.

fotoni dera

Chidwi mfundo za sayansi ndi chikhalidwe cha mabowo akuda ngati kuti nthawi zina n'zosatheka n'komwe ndikukhazikitsa mu kuwerengetsera chiphunzitso. Amadziwika kuti kuunika tichipeza photons. Akugwa pansi pa chikoka yokoka kupanga dzenje photons wakuda Arc, kudera limene iwo anayamba njira yake. Asayansi akukhulupirira kuti akaika munthu mu fotoni dera, iye akhoza kuwona kumbuyo wake.

Sikochi wapa

N'zokayikitsa kuti kanthu tepi mu zingalowe, koma ofufuza ku labu ake anachita. Ndipo ife tinapeza kuti pali chooneka cheza ndi X-ray pa unwinding lapansi. X-ray mphamvu moti ngakhale limakupatsani kutenga zithunzi za ziwalo! Ndipo ndicho chifukwa chake izi zikuchitika - chinsinsi. A kuchita chimodzimodzi zingaoneke mu chiwonongeko cha kumangidwa asymmetric mu galasi lapansi. Koma chinthu - palibe dongosolo galasi mu zomatira tepi sakutero. Choncho asayansi akhala ndi malongosoledwe wina. Kodi musaope unwind tepi ku nyumba - mu mlengalenga, palibe cheza amapezeka.

Zatsopano anthu

Mu 1746, French wasayansi, pamodzi, Jean-Antuan Nolle wansembe ankafufuza khalidwe la magetsi. Wasayansi anaganiza tikupeza zomwe ziri liwiro la magetsi. Umo ndi mmene timachitira mu amonke ...

Wasayansi anaitanidwa kuyetsa 200 Chimonko nawo ndi waya chitsulo ndi kumaliseche batire mu wretches wa Moravia Leyden mitsuko (iwo ali capacitors choyamba). ansembe onse anayankha kuti amenye pa nthawi yomweyo, ndipo zimenezi momveka bwino kuti mlingo otaya zedi mkulu.

otaika mwaluso

Chidwi mfundo ku moyo wa sayansi akhoza kugonjera ziyembekezo zabodza dunce. Nthano akuyenda pakati pa ophunzira kunyalanyaza kuti wotchuka Einstein anali achiever weniweni, sankadziwa masamu ndipo onse flunked mayeso omaliza. Ndipo kanthu, anakhala mayiko wotchuka wasayansi. Ife tifulumire kukhumudwitsa: Albert Einstein anayamba kusonyeza chidwi ndi luso masamu ngati mwana ndi ankadziwa, kutali yopambana sukulu.

Mwina mbiri za ntchito osauka wasayansi linauka chifukwa iye analibe nthawi yomweyo analowa Apamwamba Polytechnic School of Zurich. Albert kwakukuru mayeso mu sayansi ndi masamu, koma khalidwe ena chiwerengero mfundo si yagoletsa. Kukoka pa kudziwa zofunika nkhani, wasayansi m'tsogolo bwinobwino Mwapambana mayeso chaka chamawa. Iye anali ndi zaka 17.

Mbalame Pa Waya A

Kodi inu munayamba mwazindikira kuti mbalame mukufuna kukhala pa mawaya? Koma chifukwa iwo siumafa wa mantha? Chinthu ndi thupi - osati wochititsa wabwino kwambiri. Mbalame mphamvu kulenga kugwirizana yomweyi, kudzera umene ukufika panopa yaing'ono. Magetsi wakonda waya amene ali ndi wochititsa bwino. Koma m'pofunika kukhudza mbalame zambiri za chinthu, monga thandizo chinakhazikika ngati magetsi iri yofulumira thupi lake, kudzetsa imfa.

Hatches ndi magalimoto

Zosangalatsa za sayansi sangaiwale ngakhale kuonera mzinda m'mafuko, "chilinganizo 1". Sports magalimoto ikuyenda pa liwiro mkulu pakati pa underside wa galimotoyo pamwamba msewu amalenga kuchepetsa vuto la kuthamanga, zimene zingakhale zokwanira kuukitsa chidzenje chivundikiro mu mlengalenga. Icho ndicho chimodzimodzi chimene chinachitikira m'modzi wa mafuko mzinda. Chidzenje chivundikiro anakumana ndi makina zotsatirazi, moto unabuka, mtundu inaima. Kuyambira pamenepo, kuti apewe ngozi chidzenje chimakwirira ndi welded kuti felemu lija.

Natural riyakitala nyukiliya

M'nthambi wofunika kwambiri sayansi - sayansi ya nyukiliya. Chidwi mfundo pano. Kodi mukudziwa kuti zaka biliyoni zapitazo, opareshoni weniweni Oklo m'dera? Zimene zinachitika zaka 100,000 pamaso pa ureniamu pachimake si wotopa.

Choona chidwi n'chakuti riyakitala kudzipereka chilangizo - mu mtsempha wa ureniamu miyala zinagwa madzi, amene ankaimba udindo wa mtsogoleri wa manyuroni. Ndi yogwira madzi unyolo anachita pa chithupsa kutali ndi zimene ali wofooka.
