Office life before the invention of AutoCAD and other drafting software. Prior to the release of AutoCAD in 1982, engineering drawings were all done by hand using different grade pencils, erasers, T-squares and set squares.

How to study

I accidentally discovered how to compress a semester of learning into 48 hours. A grad student at MIT showed me his NotebookLM setup. I thought he was just organized. Then I watched him pass a qualifying exam on a subject he'd never studied before. Here's exactly what he did: First: he didn't upload a textbook. He uploaded 6 textbooks, 15 research papers, and every lecture transcript he could find on the subject. Then he asked NotebookLM one question: "What are the 5 core mental models that every expert in this field shares?" Not "summarize this." Not "explain this topic." Mental models. The stuff that takes professors years to develop. But the next part is what broke my brain. He followed up with: "Now show me the 3 places where experts in this field fundamentally disagree, and what each side's strongest argument is." In 20 minutes he had a map of the entire intellectual landscape of the field: the debates, the consensus, the open questions. Most students spend a full semester just figuring out what those debates even are. Then he did something I've never seen before. He asked: "Generate 10 questions that would expose whether someone deeply understands this subject versus someone who just memorized facts." He spent the next 6 hours answering those questions using the source material. Every wrong answer triggered a follow-up: "Explain why this is wrong and what I'm missing." By hour 48, he could hold a conversation with his thesis advisor without getting destroyed. The tool didn't change. The questions did. Most people treat NotebookLM like a fancy highlighter. These students are using it like a private tutor who has read everything ever written on the subject. The difference between a semester and 48 hours isn't the amount of content. It's knowing which questions to ask.

MrBeast reveals the secret to getting millions of views on social media “A big part of getting 100,000,000 views on a video is whether it’s something someone has seen before or not. There’s this analogy I like to use, if you’re driving down the road and see a cow, you’re probably not going to look at it. Who cares, you see them all the time. But if you’re driving down the road and see a purple cow you’re going to look like four times and remember it” “It’s kind of the same way on social media. If you’re scrolling through videos and it’s something you’ve seen before it’s like seeing a regular cow. But if it’s a video you’ve never seen before, like putting a bunker underground and having two people live in it, that’s the equivalent of a purple cow on social media” “Make your ideas the purple cow, don’t just be the cow”
