Space is Negative Energy

The great mystery at the heart of the Big Bang is to explain how an entire, fantastically enormous universe of space and energy can materiahse out of nothing. The secret lies in one of the strangest facts about our cosmos. The laws of physics demand the existence of something called "negative energy." To help you get your head around this weird'd but crucial concept, let me draw on a simple analogy Imagine a man wants to build a hill on a flat piece of land. The hill will represent the univ...

 "Post-Libertarian"

Brand now describes himself as “post-libertarian,” a shift he attributes to a brief stint working with Jerry Brown, during his first term as California’s governor, in the nineteen-seventies, and to books like Michael Lewis’s “The Fifth Risk,” which describes the Trump Administration’s damage to vital federal agencies. “ ‘Whole Earth Catalog’ was very libertarian, but that’s because it was about people in their twenties, and everybody then was reading Robert Heinlein and ...

 Old CRPGs are Unplayable for Modern Gamers

They had five days to play (Ultima IV), and I asked them to make as much progress as they could in that time. When we gathered to debrief in class, a few students explained how they’d overcome some of their difficulties, but the vast majority was utterly flummoxed by the game. As one of them put it, “I’d say for gamers of our generation, an RPG like Ultima IV is boring and pretty much unplayable.” After removing the arrow from my chest, I asked them to explain why. It mostly came dow...

 1980 View of Software

Software is a new enough kind of thing in the world that humans are still figuring out how to deal with it. Though it can be bought and sold, you can't see, hear, touch, taste, smell, eat, or burn it. On an unlovely flat artifact called a disk may be hidden the concentrated intelligence of thousands of hours of design, for which you are expected to pay hundreds of dollars, and which you can reproduce on your own computer with perfect fidelity in less than a minute, free. Personal computers ha...

 President-Elect Trump has a Low Signal-to-Noise Ratio

What a president says is typically allotted a ton of news value, by default, and rightly so. But it has been assigned news value because it traditionally has had a very high signal-to-noise ratio. Presidential remarks are normally so considered, vetted, poll-tested, etc. They usually are a somewhat reliable guide to the policies a president will pursue, how they’ll pursue them, etc. But Trump isn’t like that. He throws a ton of stuff out there, on Twitter and off. The signal-to-noise rati...

 Knowing Your Work isn't Good Enough

Nobody tells this to people who are beginners, I wish someone told me. All of us who do creative work, we get into it because we have good taste. But there is this gap. For the first couple years you make stuff, it’s just not that good. It’s trying to be good, it has potential, but it’s not. But your taste, the thing that got you into the game, is still killer. And your taste is why your work disappoints you. A lot of people never get past this phase, they quit. Most people I know who d...

 Hydrogen Levels in the Universe

Our Sun is significantly enriched, having formed when the Universe was more than 9 billion years old in the plane of a spiral galaxy, one of the most enriched places in the Universe. Yet, when our Sun formed, it was still made out of — by mass — 71% hydrogen, 27% helium, and about 2% “other” stuff. If we convert that into “number of atoms” and treat the Sun as typical of the Universe, that means, over the first 9.3 billion years of the Universe, the fraction of hydrogen ha...

 Transcription Fluency

When you write something down, either while taking notes or while trying to write your own original thoughts, you’re dealing with what literacy scholars call “transcription fluency”: How quickly and fluidly you can get down — “transcribe” — the stuff that’s in your head. One of the reasons we formally teach handwriting to young children is that you don’t want a bottleneck between the ideas they’re forming and the writing. If you struggle with the act of forming let...

 "Follow Your Passion" is Terrible Advice

So I started to wonder what would happen if we challenged some of these sacred cows. Follow your passion -- we've been talking about it here for the last 36 hours. Follow your passion -- what could possibly be wrong with that? Probably the worst advice I ever got. (Laughter) You know, follow your dreams and go broke, right? I mean, that's all I heard growing up. I didn't know what to do with my life, but I was told if you follow your passion, it's going to work out. I can give you 30 example...

 You Are Not the Same Person You Were as a Child

Think of an experience from your childhood. Something you remember clearly, something you can see, feel, maybe even smell, as if you were really there. After all, you really were there at the time, weren’t you? How else would you remember it? But here is the bombshell: you weren’t there. Not a single atom that is in your body today was there when that event took place … Matter flows from place to place and momentarily comes together to be you. Whatever you are, therefore, you are not...
