Blueprint "Cyanotype"

Back in 1842, Sir John Herschel invented a method of reproducing documents known as cyanotype. An existing plan drawn on translucent tracing paper could be photocopied by placing it on top of another piece of paper that has been coated with a photosensitive chemical solution (ammonium iron citrate and potassium ferrocyanide). The two layers are exposed to ultraviolet light (the sun) for a few minutes.⠀
⠀
Consequently, the bottom sheet will turn blue due to the reaction of the chemicals to the light. However, as light would not be able to penetrate through the parts of the original document where the drawing marks are, those sections would remain white on the bottom sheet.⠀
⠀
When the chemical solution is washed off the bottom sheet and the paper dried, a copy of the plan is created.⠀
⠀
Other methods of achieving the same effect have emerged since that time and have replaced this practice, but the term ""blueprint"" continues to be used until today.

Hivi hawa watu huwa wanaanzia wapi katika ubunifu wao... Wanagundua kitu na kuzodi kukiendeleza.... Waligundua simu za button zisizo na rangi, wakaja ongeza rangi... Wakaja kundua tena smartphone hamna button lakini unabonyeza kitu kina-respond... Hivi sisi hatuna akili ya kugundua? Nawashangaa sana wazungu.

Wengi tunao uwezo wakufanya yote hayo endapo wenye dhamana watatushika mikono na kutuinua.

Sio rahisi kuanzisha start-up company/products Africa ukafanikiwa bila fedha personally. Isipokuwa South Africa, Nigeria, Maroc na Egypt.

Ubunifu unakuja pale unapokua umeshatatua matatizo yako ya msingi katika maisha, afrika bafo tuna shida nyingi na matatizo kibao, ni aghalabu sana kufikiri kwa ubunifu ukiwa una njaa, maradhi na mafuriko n.k., wenzetu walishamaliza zamani sana...

Nadhani ubunifu unakuja pale unapokua na matatizo mengi. Matatizo hayo yatapelekea wewe kuwaza njia ya kuyatatua hapo ndio utabuni kitu kitakachokusaidia kutatua matatizo hayo.

Huwezi kuniambia mtu aligundua gari wakati akiwa ameshatatua tatizo la kwenda umbali mrefu kwa kutumia mda mfupi, tatizo hilo la umbali ndio lilipelekea akabuni kitu kitakachosaidia kumsafirisha umbali mrefu kwa muda mfupi.

Njaa, maradhi, mafuriko n.k ilitakiwa tubuni njia ya kutatua/kukabiliana nayo

Indeed! Na bado naamini Afrika uwezo upo lakini uwezeshaji ndio tatizo.

Nguvu zinatumika kumshusha mme wa kiafrika katika kichaka cha Women Empowerment zitaliangamiza bara lote.

Nguvu hiyo ungewekezwa katika kutatua changamoto za pamoja.

Ni ubunifu

Ni ubunifu

Wazo ndio linazaa ubunifu..ubunifu unatokana na changamoto unazokumbana nazo katika maisha..lakini yote hayo hayatawezekana kutegemea na namna unavyowaza na kufanya maamuzi..yaani lazima uwe na matumizi mazuri ya akili.
