Penrose tilings have been shown to be 2 dimensional projections of simple lattice structures in 4 or more dimensions. Which is awesome. Here is a java applet that will draw as many as you'd like. https://www.gregegan.net&#x2

Quite happy to see entropic gravity discussed here. One thing I really like about EG is that it ought to be very testable. For example, there are a few observations of very diffuse galaxies that exhibit very little if any dark matter behav

It's just a pithy quote that is obviously false and yet very difficult to unlearn. People with different values can be equally happy. There are tons of objectively crazy people who are happy, and even a few who are rich. There lots of

I think to go really fast, you'll have to introduce a new data structure, similar to git's. (I'm thinking it's a trie, but I'm coming up zero evidence for that.) Calculating the dependency graph could be nearly inst

I'll try to restate. I was under the impression that entanglement implied what the paper calls "common history", such as when an excited calcium atom decays to its ground state and produces two entangled photons. I also under

I'm not an expert, but I thought the paper was more novel than that, in that it challenges my picture of entanglement. The paper demontrates entangled behavior with photons with no common history. They are "identical" in thei

Rich Hickey: "By default, an object-oriented program is a graph of mutable objects. That's a very, very difficult thing to think about, debug and keep running." Basically OO is exactly the worst to deal with increasing comple

I don't understand the physics here... photons are bosons, and bosons pass through each other. Is the idea that the photons passing through the fluctuating vacuum occasionally produce fermions that can bump into each other, and then wh

I find this totally amazing. This feels like it could be an extremely sensitive and fast signaling channel. I wonder what the relationship of these atomic vibrations have to the microscopic behavior of electric current. I.e. can current be

I don't see it this way at all. It's more like using the compiler to write good unit tests. That's the hope anyway.

I sympathize with you but I always follow develooments in this space because the potential upside is so awesome. Excellent mathematicians are using theorem provers to check their logic, and such a system brought to say the compilation of

I feel pretty good reading this. I like that you can write listMyType := List(MyType). I'm still a bit dubious about contracts; they're so similar to interfaces. If there was a way to derive or relate a contract to an interface th

I'm just a reader, but Kip Thorne doesn't agree with your picture. In his book, he claims you wouldn't notice passing through the event horizon, except for extreme tidal forces that would tear you apart. The time freezing and

No the finding is that they tested GR near a boundary, where you might expect find issues, and found that it held up. The title and the comment Ghez makes about the interior of a black hole are a bit misleading. As far as interiors of black

True, it's a different picture. It's about how to create a really efficient computing mesh. If unikernels are faster (they start faster, then they run faster), and simpler, and you offload security and topology to kubernetes (or s

I find it very relaxing and accessible. I mean I guess guitar is too, with a lot more literature. But a big attraction of the banjo for me was the open source nature of folk music.
