A Children’s Picture-book Introduction to Quantum Field Theory

“In this post I want to try and paint a picture of what it means to have a field that respects the laws of quantum mechanics.  In a previous post, I introduced the idea of fields (and, in particular, the all-important electric field) by making an analogy with ripples on a pond or water spraying out from a hose.  These images go surprisingly far in allowing one to understand how fields work, but they are ultimately limited in their correctness because the implied rules that govern them are completely classical.  In order to really understand how nature works at its most basic level, one has to think about a field with quantum rules.”

Does Macbeth possess a weak character? What’s driving his actions? Is it his own ambition, the witches’ manipulation, or Lady Macbeth? I’m not as well versed in Shakespeare as you. I might be way off base. She seems to berate him for his lack of fortitude and even questions his manhood. Is he a puppet or does he need to prove her wrong? As the “death toll rises” does he continue because he’s confident or is he caught in a rip-tide that he can’t escape? Congrats on Saint Louis. Great blog!

How (and Why) SpaceX Will Colonize Mars – Page 2 of 5

“Landing on the moon is in the same category as putting the first man in space or the first person climbing Mt. Everest—it’s a great achievement for mankind. But if the first ocean animal to touch dry land simply lay there for a minute before being washed back into the ocean, it would not qualify as a giant leap for life, and the moon landing shouldn’t either. It’s only when certain mutated fish began to live on land in a sustainable way that life as a whole made a giant leap. It’s colonizing Mars permanently that will be a giant leap for mankind.”

“It’s aspirational stuff, and as he riffs I notice the team shares an unexpected point of inspiration: Disneyland. “Walt Disney believed that he could take a fantasy world from cinema that he was making, and basically create a physical experience that you could walk into,” Gaeta says. “This is like a 2.0, supercharged version of the same philosophy.” It makes sense; when you zoom out, Gaeta’s grand vision resembles nothing so much as a digital Disneyland, and Walt Disney Imagineering even has a satellite team embedded at ILM for working on Disneyland attractions. “There’s a lot to be learned from those formats in the parks.””

I spent a weekend at Google talking with nerds about charity. I came away … worried.

The movement has a very real demographic problem, which contributes to very real intellectual blinders of the kind that give rise to the AI obsession. And it’s hard to imagine that yoking EA to one of the whitest and most male fields (tech) and academic subjects (computer science) will do much to bring more people from diverse backgrounds into the fold.

Lunch with the FT: Mariana Mazzucato

“We are living in a depressing era in which we no longer have courage. We no longer think governments should have missions. But the market never chooses anything. IT wasn’t chosen by the market. Biotech wasn’t chosen by the market. Nanotech wasn’t chosen by the market. So why should green technology be chosen by the market? It comes back to the austerity craziness that we’re in today where governments are not allowed to dream; and green is a dream.”

The Future of Work: Why Wages Aren’t Keeping Up

“The custom is to think of value added in a corporation (or in the economy as a whole) as just the sum of the return to labor and the return to capital. But that is not quite right. There is a third component which I will call “monopoly rent” or, better still, just “rent.” It is not a return earned by capital or labor, but rather a return to the special position of the firm. It may come from traditional monopoly power, being the only producer of something, but there are other ways in which firms are at least partly protected from competition. Anything that hampers competition, sometimes even regulation itself, is a source of rent. We carelessly think of it as “belonging” to the capital side of the ledger, but that is arbitrary. The division of rent among the stakeholders of a firm is something to be bargained over, formally or informally.”

Science vs. religion… or science and religion? « The Berkeley Blog

“By a huge margin, a Gallup Poll shows, Americans disagree that “science and religion are incompatible” (69% to 17%). Thus, underlying Americans’ views, these studies suggest, is not a simple divide – knowledge versus ignorance, Reason versus Faith, or science versus religion – but a complex combination of science and religion. Science is appreciated except for its claims about creation. And there are, at more sophisticated levels, some who combine religion even with acceptance of the big bang and evolution.”

Zero to Mandalay: Myanmar and the game nobody wins

“I’d seen enough chinlone, or thought I had seen enough. I still honestly can’t say whether watching five minutes of the game or five days’ would be enough. It was hard to say you’d even seen it, or that it was even you seeing it. Something kind of terrifying happened if you watched enough chinlone: there was nothing, a perfect blankness between annihilation and calm.”

Perfect Compromise: Welcome to the nerve-wracking reality of being Finland.

“What distinguishes Finland from France and even Hungary is its geographic proximity and historic intimacy with Russia. So another layer of romance and danger is added: Russia appeals to those who need to side with the more powerful. This is exactly what scares Sofi Oksanen and inspires Johan Bäckman.”
