⭐️Subscribe and get on the science spaceship ⭐️: / @yousciences The first time we encounter the concept of integral we are taught a procedure for dividing a domain of a function into many small pieces whose sum gives us the area under the graph! You might apparently imagine that only this type of integral exists, the Riemann one. But that is not the case! The most powerful of all is the Lebesgue Integral! Which solves the problem of integration even for strange functions like the Dirichlet one and other similar devilries. In this video we will start from the beginning, from the rudiments of Riemann integration and we will discover how from this we move on to a new ingenious integration procedure, the Lebesgue one, we will talk about the measure theory of Borel sigma algebras and null measures; all concepts that are the foundation of advanced sectors of engineering and physics such as quantum mechanics, signal theory, integral transforms etc. #lebesgue #integration #riemann #mathematics #physics #doctorgiux #giux #yousciences #science #maths #geometry ⭐️SUPPORT THE PROJECT⭐️: https://www.paypal.com/donate/?hosted... ????Our Subscribers????: https://www.yousciences.it/membership/ Where to find me ????: ➤YOUSCIENCES: https://www.yousciences.it/ ➤OFFICIAL WEB SITE: https://www.giuseppesottile.it/ ➤INSTAGRAM: @yousciences @___giux___ ➤FACEBOOK: / giuseppe.sottile.56 ➤LINKEDIN: / giuseppe-sottile-3a8599b0 ➤TELEGRAM: https://t.me/joinchat/abNZYJqE7MVlODA0 ➤TIKTOK: https://www.tiktok.com/@yousciences?l...
