Help the project: / vertdider You've probably heard of the imaginary unit, or "i." It's a number that, when squared, gives -1 (minus one). For those who remember from school that the result of squaring is always positive, this may seem strange. Don't worry, for a long time the idea of ​​square roots of negative numbers baffled the greatest mathematicians. Nevertheless, imaginary numbers have entered everyday life and have proven their usefulness: with their help, we not only learned how to solve some equations, but also got the opportunity to learn a little more about how the Universe really works. The story of their appearance, which we believe is quite worthy of a film adaptation, will be told by Derek Muller in a new video. If you want to dive deeper into the mathematical side of the issue, we also recommend watching the video from the Welch Labs channel “Imaginary Numbers Are Real”: • Imaginary Numbers Are Real: #1-13 [Welch Labs] Translation: Alexey Malov Editing: Elena Smotrova Scientific editing: Kirill Tsiberkin Voiceover: Dmitry Chepusov Sound editing: Andrey Fokin Video editing: John Ismailov Cover: Andrey Gavrikov Thanks for your support on / vertdider Vert Dider voiceovers are released with your help: Mikhail Stolpovskiy, Maria Zvereva, Pavel Dunaev, Nick Denizhenko, Oleksii Leonov, Yegor Barakovskiy, Tatyana, Martynov Pavel, Kirill Seleznev, Dmitrii komarevtsev, toshego, Sergey Skrypnyk, Illarion Petrov, Andrew Dzhur, Evgeny Kolmakov, Andrey Chizh, Linar Khusnullin, Dmitry Glaznev, Ilya, smiler, Anton Malinin, Roman Inflianskas, Aleksandr, Maxim Syunikov, Oleg Zingilevskiy, Serega Beltser, Rashid Nasibulin, opperatius, Alena, Vitaliy Vachynyuk, Nika Kalmykova, Evgeniy Selmenev, Yaroslav Atrokhov, Sergii Cherepanov, Vladimir Kashutin, Pavel Parpura, Anton Bolotov, Yevhen, Sergei W, Kosoy, Mikhail Pankin, Katoto Chan, Anton Makiievskyi, angel, Sergey Nazarov, Mikhail Kuznetsov, Lev Zaplatin, Ivan Egorov, Exordin, Victor Cazacov, Svetlana Zabegaeva, Anastasia Ermilova, Ivan Bondarenko, Alexander Kulikov, K IM TKHE SIK, Kirill Zaslavskii, Polina Markina, Tray Hard, Valeriy Dubrava, Evgeny, Sergey Andreev, Leonid Korobov, mol9ko, Taleh Zaliyev, Addon, Irina Slavgorodskaya, Arthur Skobara, 666.13FM, Andrew Rumyantsev, Marianna Sumina, Maria Baranova, Maxim Arkushin, Dmitry, Oleg Kovalov, Vadim Cpp, Roman Rogachev, Artem Amirbekov, Dzmitryi Halyava, Nastya P, D mitriy Lashtaba, Ilya Alexeevsky, Alexander Balynskiy, Maxim Ivanov, Ihar Marozau, Alexander, Maria Tronina, Alexander Gorodok, Ivan Iakimov, Alexander Zimin, Otto Kester, Claudia Barzaeva, Lirin Alex, Konstantin Pesyakov, Viktoria, Olga Podolskaya, Alexey Kukushkin, F23D24, Pugachev Peter, Olga Shistareva, Irina Shakhverdova, Dmitriy Omelyan sky, Aleksey Sazonov, Vladimir Goshev, Vladyslav Sokolenko, Anton Novozhenin, Spartak Kagramanyan, Alexander Falaleev, Evgeny Vrublevsky #VertDider #Veritasium Studio website: http://vertdider.tv We are on social networks: - http://vk.com/studio_vd - https://t.me/vertdider - /vert_dider - http://coub.com/vert dider Permission to publish: https://bit.ly/2SFhrHZ © / veritasium Source: • How Imaginary Numbers Were Invented
