Matemati\u010dki \u010dvorovi <\/h2>\n\n\n\n

Priznaj, sigurno nikada nisi pomislio\/pomislila da ti matematika mo\u017ee pomo\u0107i zapetljati ili otpetljati neki \u010dvor! Do\u0111i na Korzo i poku\u0161aj se otpetljati!\u00a0<\/p>\n\n\n\n

Tajne \u0161ifriranja <\/h2>\n\n\n\n

Jesi li se ikada pitao\/pitala kako je Cezar skrivao tajne od svojih neprijatelja? Jesi li ikada \u010duo\/\u010dula za Enigmu? Zna\u0161 li kako je radila? Zna\u0161 li tko ju je \u201eprobio\u201c? <\/p>\n\n\n\n

\u0160ifriranje je maskiranje ili pretvaranje izvornog teksta u \u0161ifrirani tekst po odre\u0111enom klju\u010du. Otkada postoji civilizacija postoji i potreba za \u0161ifriranjem. U ovoj \u0107emo aktivnosti prikazati kratak vremeplov \u0161ifriranja.  <\/p>\n\n\n\n

Pridru\u017ei nam se i oku\u0161aj se u \u0161ifriranju! <\/p>\n\n\n\n

Pokusi u ekstremnim uvjetima <\/h2>\n\n\n\n

Kako se pona\u0161aju tijela u vakuumu? Kako se na Zemlji mogu simulirati vremenski uvjeti kakvi su na Neptunu? Mo\u017eemo li napraviti lebde\u0107i vlak? <\/p>\n\n\n\n

Odgovorit \u0107emo na ova i jo\u0161 mnoga pitanja izvode\u0107i zanimljive pokuse na ekstremno niskim temperaturama i tlakovima. Demonstrirat \u0107emo \u0161to se doga\u0111a kada predmete prelijemo teku\u0107im du\u0161ikom ili kada ih stavimo u vakuum. Hla\u0111enjem visokotemperaturnog supravodi\u010da teku\u0107im du\u0161ikom proizvest \u0107emo supravodi\u010dki supermagnet, koji je nekoliko stotina puta ja\u010di od obi\u010dnih magneta. Izgradit \u0107emo jednostavan model levitiraju\u0107eg vlaka i demonstrirati kako magneti uzrokuju lebdenje vlaka iznad tra\u010dnica. <\/p>\n\n\n\n

Iva \u0160ari\u0107<\/strong> diplomirala je fiziku i politehniku na Filozofskom fakultetu Sveu\u010dili\u0161ta u Rijeci 2007. godine. Doktorirala je fiziku 2014. godine na Prirodoslovno-matemati\u010dkom fakultetu Sveu\u010dili\u0161ta u Zagrebu s temom EPR spektroskopija krute trehaloze: utjecaj neure\u0111enosti matrice na dinamiku paramagnetskih centara<\/em> (pod mentorstvom dr. Marine Ilakovac Kveder, Institut Ru\u0111er Bo\u0161kovi\u0107). Od 2014. do 2017. bila je poslijedoktorandica na Odjelu za fiziku Sveu\u010dili\u0161ta u Rijeci. Od studenog 2017. zaposlena je kao docent na Odjelu za fiziku i Centru za mikro- i nanoznanosti i tehnologije Sveu\u010dili\u0161ta u Rijeci.

Daria Jardas<\/strong> diplomirala je In\u017eenjerstvo i fiziku materijala na Odjelu za fiziku Sveu\u010dili\u0161ta u Rijeci 2019. godine. Trenutno je zaposlena kao asistentica na Odjelu za fiziku i u Centru za mikro- i nanoznanosti i tehnologije Sveu\u010dili\u0161ta u Rijeci. Njezino su podru\u010dje istra\u017eivanja fotokataliti\u010dka svojstva poluvodi\u010dkih oksida.<\/p>\n\n\n\n

Zemlja je stara koliko je Korzo dug?<\/strong><\/h2>\n\n\n\n

Zemlja je nastala prije 4 540 000 000 godina, odnosno 4.54 x109<\/sup> godina, otprilike \u010detiri i pol tisu\u0107e milijuna godina. Jednostavnije, na\u0161 je planet nastao prije \u010detiri i pol milijarde godina, a slo\u017een \u017eivot, poput biljaka i \u017eivotinja koje bismo danas prepoznali, pojavio se prije otprilike 550 milijuna godina. Kako bismo si mogli do\u010darati ovo nevjerojatno golemo vrijeme, mo\u017eemo cijeli \u017eivot na\u0161eg planeta svesti na du\u017einu Korza, odnosno na 460 m. Pomo\u0107u originalnih muzejskih predmeta, pripremljenih grafi\u010dkih oznaka i zajedni\u010dkom raspravom, \u0161eta\u010di Korzom upoznat \u0107e se s geolo\u0161kim razdobljima i razvojem \u017eivota na Zemlji. Cilj je ovoga edukativnog programa i osvijestiti posjetitelje o u\u010dinku koji \u010dovjek, u relativno kratkom vremenu, ima na Zemljin ekosustav te o va\u017enosti o\u010duvanja bioraznolikosti. Nezamislivo dugu i turbulentnu pro\u0161lost na\u0161eg planeta poku\u0161at \u0107emo spoznati kroz du\u017einu na\u0161ih koraka. Kroz edukativnu program i vodstvo muzejskih prirodoslovaca poku\u0161at \u0107emo odgovoriti na pitanja poput: Kako je izgledao prvi \u017eivi organizam? Kad se \u017eivot preselio na kopno? Kad je zamirisao prvi cvijet? Tko je stariji, dinosaur ili morski pas? Kad su na\u0161i preci po\u010deli hodati Zemljom? <\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
