Phenomens

Id correct formulation uns physic theoria naudht id neud concepten qua, in-kap, sont id fruit ios cadadien experience im menscen, yed ne sont semper exact-ye adaptet ei description ios causal structure ios universe. Physique maght yinjier bihe prabh-ye ayt un sok po id adaptation ios menscenbahmen ad nature. Besonters important in tod regard sont ia soks po symmetrias existend in nature, taghi symmetrias sont guides qua nos istifsareihnti de ia real-ye significant concepts. Ne est lakin sure od tod adaptation os bahmen ad nature sia perfect-ye parakapt, ni hatta aunfin-ye perfectible. Sem difficultats os quantic mecanique maghient habe ter ir origin. 
Id physic theoria ambghehrdt, unte sien antslehnken, stets meis phenomens. Tod kweitu deict id crehscend adequation iom general concepts ed prabhils ad nature : est uno meid os ids progress. 
 
==Materia==
Skeipsubstance iom corpsen, materia consist different elements : atoms, ions au molecules. Atoms sonti meg smulk particules, compost ab un eten ed electrons (negative elementar electric charges). Atoms sont electric-ye neutral irghi eten behrt tant positive charges quem ir electrons behrnti negatives. Ions sont atoms leusus au gainus electrons sub id action om nieber electrons; sontghi electric-ye charget particules. Molecules sont atomenjamiyas. Materia ghehdt skaue different stands (dependend id prokwtat sienen skeipelements): in un solid, ta elements sont compagen ed quasi still; in un liquid, quayque dar-ye prokwem mutu, ghehde move; in un gas, trehcent leur-ye ed ghehde occupe id hol volume ambh se. Maunga corpsa (kam wed) ghehde uperlites reversible-ye ex un stand do alyo. Ia tri variationstypes (fusion/solidification; liquefication/sublimation; steumen/liquefication) ghehde bihe provoquet ab temperature changes, yed idpet uperleiten ex oin stand do alyo tyehct ye constanto temperature.
 Id electromagnetic spectrum consist vasya possible energia nivells qua luce ghehdt habe. Tolke de energia est kam tolke de wandlonge; it, id electromagnetic spectrum ambghehrdt quanta wandlonges luce ghehdt habe, ex tusents kilometern do femtometers. Itak pleista schematic kips ios spectrum swehde habe un logarithmic maschtab.
==Luce==
Ia objects qua vidmos iti sont luciswors. Uters, qua emitte ir wi luce, sont kalen "primar luciswors". Alters, qua reyeise id luce quod dakent iti sont kalen "secundar luciswors". In un transparent ed homogene milieu, luce se propaget seid. In kenos, ids propagationsyrat nact 300 000 km/s. In alter transparent milieus (air au wed), tod syrat est slaber. Un luce bam est uno menghia om gwayderstrehls ex id sam iswor. Sowels kweitos consist pelu monochromatic luces (radiations) aunstehget kwehrnd-ye idso spectro med un prisma. Radiations maghe bihe classifieta do sept colortrends : ia deuspontcolors (violett, indigo, blou, glend, gehlb, naranji, rudh). Id color uns objectios dependt sammel id composition ios luce quod beleuct id ed sien wi suedsa de transmission, absorption ed diffusion om certain radiations. Beluct ab diewo, sem materials reyeise vasya dact monochromatic luces : kwehkent kwit. Alya absorbe vasya, sont kwaht sword. Pleista reyeiste tik oin part ed kwehke om divers colors. Id additive synthese os luce est id addition iom different colorlucen kyep un ecran (tod proceddat est nudt kay reconstitue id colorkwiter in un televisor mathalan). Id substractive synthese iom colors est id eliminationo med filters om certain colorluces (tod proceddat est besonters nuden in color photographia).
 Mix om substractive colors sekwent id CMY model, yani, in Englisch : Cyan-Magenta-Yellow.
==Force==
In physique est kyust ka force cada cause quod ghehdti deforme un corpos, modifie idso stand os rahat au os mov. Sei sem forme, kam mathalan un hand quod pusct un ball, seuwt un trehc, idwert tyeict un wehrg. Quan un systeme esti tyeicmon sem wehrg, idwert behandt energia. Sem corpsa behande energia ob ir position : un pehdmon corpos xeiht un potential energia, quod vighehdiet trudes un corpos ender se. Tod energia est kalt potential gwarutatsenergia. Est egal ei multiplication ios masse ios corpos, ios intensitat os gwarutat ed ios hoge ios pehden. Uno movend corpos hassilet ob tod mov un energia kalt "kinetic", egal ei semi-multiplication sienios masse med id quadrat os sien syrat. Id energia ghehdt se transforme. Also, id potential energia ios wed ub un wedfall ghehdt bihe transformet do kinetic energia wehrteihnd-ye un synchronmotor, quod transformet id do electric energia. It se conservet energia. In systeme-on, se transformet sub different formes eni tod-on we se transfert alyi systeme. Est kalen "stieure uns forcensysteme" id quotient ios product wehrg med id wakt tohrben kay parkwehre id. Id moment uns force taken do sem pointo M binisbat sem point O est id multiplication ios vector skeipend id force med distance inter O ed id sprijinseid ios force. Est kalen forcencouple un systeme om dwo samwirt forces, samt parallel actionseids om witer directions. Id moment ios couple est egal ei multiplication ios wirt uters force med id distance separend ir actionseids.

==Chemic reaction==
Un chemic reaction est un transformation in quos druna corpsa dispareihnt (reagents) ed alya appareihnt (products). Unte un chemic reaction, ia molecules qua compone ia reagents brehge ed leure ir atoms. Ta se jamiye als ed skeipe alya molecules, qua compone ia products. In id druna ios reaction, iaghi atoms bihnt conserven. Id chemic equation permitt uperwehrte id reaction. Tod biht scriben placend-ye levi ia reagents ed dexi ia products ed equilibernd-ye poskwo med coefficients ant ielg formule kay id numer atomen sia id samum ambi id isu. Sem reactions produce wierme, sont kalen "exothermic", alya naudhe we absorbe sem, sont kalen "endothermic". Combustions sonti chemic reactions, quer un dawti uniet-se uni oxidant (ops oxygen) producend-ye wierme. Sei id combustion est meg oku, id sleuren os wierme est kafi pro kandihes id dawti. Estwert tun oku combustion. Sei id combustion est lent, estwert oxidation, kam in id fall os sider in presence os madh air. Sei id dawti-comburanto mix est opnost med oxygen, id combustion sessiet complete. Sei bilax tod mix est pior comburantorm, id combustion est incomplete. Daydey bihti tolken de oxidation quan id reaction leuseiht un atom sem electrons. Id invers operation est kalt un reduction. Quan un chemic reaction uns oxidant ep un reductor comprindt sammel un reduction ios oxidant ed un oxidant ios reductor estwert un redoxreaction. In id reaction 2CuO + C > 2Cu + CO², biht prispohct sammel id oxidation os carbon ed id reduction ios cuper oxide. Id cuper est id oxidant ed id carbon id reductor.
