The lecture was great. I've never been very good at tensors, and struggled at that bit whilst at school. <br /><br /> Anyway this lecture made it all super clear, and it was a great introduction to them. HOWEVER the lecturer makes a mistake in a small detail, whilsts discussing the number of components in a tensor with respect to a basis across the vector space. <br /><br /> #<span class="tag"><a href="https://indy.im/tag/math" rel="tag">math</a></span>277435http://activitystrea.ms/schema/1.0/post2019-07-25T10:46:29+00:002019-07-25T10:46:29+00:00http://activitystrea.ms/schema/1.0/personhttps://indy.im/user/5boneidolIndebted to tech, or is that in technical debt.
