# Cambridge University: Quantum Field Theory

Ok so it seems like a good time to update the lecture section. Here we have a full course on quantum field theory. Ed Witten, when asked about quantum field theory, described it as the hardest theory in modern physics by far. However my friends, don’t be discouraged, there are plenty of great resources online that can help you out in taming this hard theory. One of the best resources is this course delivered by David Tong. The course contains 14 lectures focusing on the basics of QFT. The only obvious drawback is, as you might have noticed, the quality of these videos. Luckily, the videos can be downloaded in various formats (including the slides showing the blackboard) on the Perimeter Institute **website**. For more lectures visit the links below.
