About

Na kanale Copernicus popularyzujemy naukę. Wyjaśniamy obowiązujące teorie, czytamy nowe publikacje, przedstawiamy historyczny kontekst odkryć naukowych. Kanał związany jest z Centrum Kopernika Badań Interdyscyplinarnych Uniwersytetu Jagiellońskiego. Centrum powstało w 2008 r. z inicjatywy Michała Hellera, laureata Nagrody Templetona; od 2014 r. współorganizuje Copernicus Festival. Jeśli doceniasz sposób, w jaki popularyzujemy naukę, możesz nas wesprzeć. Dobrowolne darowizny można wpłacać na konto Fundacji Centrum Kopernika: 92 1090 2053 0000 0001 2289 4260 z dopiskiem "na działalność statutową fundacji". https://www.copernicuscenter.edu.pl/fundacja

Video Description

Liczby zespolone były niechcianym dzieckiem matematyki. Choć pierwiastki z liczb ujemnych rozważano już prawie 500 lat temu, przez wieki uważano je za nonsens, za "urojenie" bez związku z rzeczywistością. Tymczasem dziś trudno wyobrazić sobie bez nich nie tylko matematykę, ale także fizykę (zwłaszcza kwantową) i wiele dziedzin techniki. Skąd wzięły się liczby zespolone? Jak się mają do liczb rzeczywistych i do rzeczywistości jako takiej? Co ma na myśli fizyk matematyczny i noblista Roger Penrose, gdy pisze o ich "magii"? To wszystko i więcej w kolejnym mini-wykładzie z serii "Zacznijmy od zera". Polecana książka: R. Penrose, Droga do rzeczywistości. Wyczerpujący przewodnik po prawach rządzących Wszechświatem, tłum. J. Przystawa, Prószyński i s-ka, Warszawa 2006. Dofinansowano z programu „Społeczna odpowiedzialność nauki” Ministra Nauki i Szkolnictwa Wyższego w ramach projektu „Otwarta Nauka w Centrum Kopernika".
