Nkhondo ya Magetsi gha Direct na Alternating Current yikaŵa mphindano ya malonda na sayansi pakati pa Thomas Edison, Nikola Tesla na George Westinghouse mu vyaka vya m'ma 1880 na 1890. Edison wakakhozga magetsi gha DC, apo Tesla na Westinghouse ŵakakhozga magetsi gha AC. Chinthu chikuru mu mphindano chikaŵa umo magetsi ghangatumizgikira mtunda utali kwambura kutaya mphamvu zinandi. AC yikaŵa yakwenelera pa kutumiza magetsi kutali, ndipo yikawoneska nkhongono yake pa Chiwonesko cha Charu cha Chicago mu 1893 na ntchito ya magetsi ku Niagara Falls. Edison wakagwiliskiranga ntchito viyelezgero vya ŵanthu na nyama kuti walongore ngozi ya AC, kweni AC yikazgoka nthowa iyo yikagwiritsidwa ntchito chomene. Nkhondo iyi yikasintha umo charu chikaŵikira maukonde gha magetsi na umoyo wa mazuŵa ghano. AC yikathereska mphindano ndipo yikazgoka nthowa yakumanyikwa chomene mu charu chose lero.

Chigaŵa cha Khoma la Berlin icho chikawoneka mu 1989
Mu 1918, Germany yikapharazga kuti yizamuŵa charu cha boma la ŵanthu m’malo mwa ufumu.

Mndandanda uwu ngwakukhwaskana na charu cha Brazil
ŴaPalaw'an ni gulu la ŵanthu ŵakwambilira ŵa ku Philippines awo ŵakukhala chomene mu chigaŵa cha Palawan. ŴaPalaw'an ŵali na umoyo wakukolerana chomene na thengele, ndipo ŵakujipwelelera mwa kusaka, kusanga vyakurya, kukola somba, kusanga uchi na kugwiliskira ntchito vyakumera vya mu chilengiwa. Ŵali na umanyi wakuzama wa vinyama, makuni, milonga na malo ghawo, ndipo ŵakugwiliskira ntchito vinthu vya mu thengele pa vyakurya, nyumba na vinthu vinyake. Ŵanthu aŵa ŵakumanyikwa chifukwa cha luso lwawo lwa kusaka na mivi, mipondo na vinthu vinyake vya chikhalidwe. Mazuŵa ghano ŵakukumana na kusintha kwa malo na umoyo, kweni ŵakulutilira kusunga mitheto, chiyowoyero na maluso gha makolo ghawo. Palawan yikulutilira kuŵa malo ghakuzirwa chomene pa umoyo wawo.

Malo ghakuzizwiska
Meteora ni malo ghakuzizwiska mu Greece agho ghali na mizati yikuru ya mwala na matchalitchi ghakale agho ghazengeka pachanya pa miyala. Para zuŵa likusweka, ungweru ukuŵika mitundu yakupambanapambana pa miyala na nyumba zakale, ndipo malo agha ghakuwoneka ghakuzizwiska chomene. Meteora yili pafupi na Kalabaka mu chigaŵa cha Thessaly, ndipo ghali na mapiri, mphanga na malo ghakupambanapambana gha chilengiwa.

Mazuŵa ghano Ŵalendo ŵakiza kuwona miyala na matchalitchi, ndipo Meteora yili pa mndandanda wa chiharo cha charu chifukwa cha kuzirwa kwake. (Nkhani yose...)
Chithuzi cha mwahuno
Khoma Likuru la China ni dongosolo la makhoma na malibwe ghakuvikilira ilo likujumpha mu vigaŵa vinandi vya China. Vigaŵa vyakwambilira vikazengeka mu nyengo za ufumu wakale, apo vigaŵa vinandi ivyo tikuwona lero vikakhazikiskika mu nyengo ya Ming dynasty. Khoma likukwera pa mapiri, zigwa na malo gha chipalamba, ndipo lili na watchtowers zinandi. Likazengeka kuti livikilire mphaka za kumpoto ku ŵankhondo ŵakufuma ku vigaŵa vinyake vya Asia. Makhoma gha malibwe, njerwa na dongo ghakagwiliskirika ntchito mu vigaŵa vyakupambanapambana. Mu 1987, Great Wall yikaŵa UNESCO World Heritage Site. Nangauli likumanyikwa nga khoma limoza, kweni ni maukonde gha makhoma ghakazengeka mu nyengo zakupambanapambana. Ŵalendo ŵanandi ŵakwiza ku Mutianyu na Badaling chifukwa cha nthowa zake na mawonekero. Para dzuŵa likuloŵa, khoma likulondezga mapiri nga njoka yitali. Ni chimoza mwa vimanyikwiro vikuru vya China.
