Is War Over? — A Paradox Explained

Kurzgesagt
10 vistas · 7 años hace

We live in the most peaceful time in human history. Wait, what? Seriously? That can't be right, there are more wars than ever! Well, no and they're killing fewer and fewer people, even though the world population is at an all-time high...and the numbers prove it! We explain how we came to this conclusion, and why war might... go away.

Videos, explaining things. Like evolution, time, space, global energy or our existence in this strange universe.
We are a team of designers, journalists and musicians who want to make science look beautiful. Because it is beautiful.

The music for the video is available here if you are interested:

Banking Explained – Money and Credit

Kurzgesagt
10 vistas · 7 años hace

Banks are a riddle wrapped up in an enigma. We all kind of know that they do stuff with money we don’t understand, while the last crisis left a feeling of deep mistrust and confusion. We try to shed a bit of light onto the banking system. Why were banks invented, why did they cause the last crisis and are there alternatives?

Thanks to all the YouTubers who supported us!!!

Being a citizen of the European Union means that many aspects of our lives are regulated by a weird entity. It feels like a huge bureaucracy is making decisions over our heads. How democratic is the EU really and does your vote actually affect anything?

¿Quiere saber más sobre la teoría del caos y los sistemas dinámicos no lineales?
Echa un vistazo: https://ve42.co/chaos-math
Hace tiempo que quería hacer un video sobre el caos. Fue desde que leí el fantástico libro de James Gleick, Chaos. Espero que este video dé una idea del espacio fásico: una imagen de los sistemas dinámicos en los que cada punto representa completamente el estado del sistema.
Para un péndulo, el espacio fásico es solo bidimensional y se pueden obtener órbitas (en el caso de un péndulo no amortiguado) o una espiral interna (en el caso de un péndulo con fricción).
Con las ecuaciones de Lorenz necesitamos tres dimensiones para mostrar el espacio fásico. Se dice que el atractor que encuentras para estas ecuaciones es extraño y caótico porque no hay un bucle (loop), solo curvas infinitas que nunca se cruzan. Esto explica por qué el movimiento es tan impredecible: dos condiciones iniciales diferentes que están muy juntas pueden terminar arbitrariamente separadas.

Misconceptions About Heat

When we touch something that is hot or cold, what are we actually sensing? Is it the temperature of the object, or the rate at which heat flows between the object and our hand?

La biología celular nos da pistas de por qué los humanos envejecemos y las langostas no lo hacen.
SUSCRÍBETE ahora para ver todos nuestros videos: http://bit.ly/Suscribirse_Veritasium_en_español

Siempre nos hacemos preguntas como:
¿Cuál es la esperanza de vida? ¿Cuánto tiempo de vida nos queda?
¿Porqué envejecemos? ¿Cómo rejuvenecer o detener el envejecimiento?
Visitamos a la doctora Ginty, quien nos contó acerca de su investigación sobre los telómeros y la telomerasa. Acompáñenme a descubrirla para intentar responder alguna de esas preguntas.

Las animaciones son de la película ganadora del Emmy 'Immortal', reproducida aquí por cortesía de December Media y Genepool Productions (anteriormente Pemberton Films)

Un agradecimiento especial a la Dra. Fiona Ginty, Científica Principal del Grupo de Ciencias de la Vida y Diagnóstico Molecular en GE. Su investigación se centra en obtener imágenes de diferentes proteínas dentro de la célula. Es una técnica muy poderosa y hermosa.
