If you want to look at that, there is lots of stuff online if you search terms like “half adder”. I don’t really recommend this stuff but maybe watch a 15 minute video to get a rough idea of what it’s like and see how much it interests you. Some of this stuff is covered in Feynman’s lectures on computation (I like that book but it’s technical and unnecessary) and I’m sure it’s in many textbooks. > > Let me know how that goes and what you want to do. We could potentially move on to grammar. I watched this computerphile video on xor and the half-adder: [![](https://discuss.criticalfallibilism.com/uploads/default/original/2X/7/7d18d7c782213a4da8e1846baf3745b4b309019e.jpeg "XOR & the Half Adder - Computerphile") ](https://www.youtube.com/watch?v=VPw9vPN-3ac) I liked idea of the inputs of the two different gates of the half adder being in parallel and so being fed the same inputs. I like electronics, and have some experience with basic analogue circuits. I think for now though I’d like to move on to something different. I skimmed the first couple pages of the introduction of the Feynman Lectures on Computation and I think I’d like to read it. --- _[View the full topic](https://discuss.criticalfallibilism.com/t/lmd-async-tutoring/1933)._
