So we've hit a wall in trying to understand how dark energy works or how its parameters arise. But I don't think it's logical or helpful to conclude that an anthropic explanation is the only option we have left. Maybe we just

Speaking of freaky coincidence: I went to this site, and it asked me my date of birth, before telling me how long I had left to pursue my dreams, on what happened to be my first experience on my 40th birthday.

Elon has also spoken of thinking from first principles of physics for getting humans into space, particularly in developing the Grasshopper reusable launch vehicle.

Well said. How you analyze and solve problems yourself is different than how you first introduce your resulting idea to someone who's never heard of it.

Elon Musk answered a similar question, and identified drive as the only relevant factor: "How do you stay focused, motivated, and maintain enthusiasm when things don't go the way you'd hoped? "I think my, sort of, drive

Sounds like not at the same time, though. He said the site was acquired in May 2013 [1], while this post says he is starting there in November, and his front page still says he works at room77.com [2]. Makes me curious. 1. http:/&#x2F

This post reminded me of pg's advice for how to get startup ideas. Compare: "I have 5+ side projects. I’d like to make businesses out of them, but I often lose interest after a couple weeks. Asterank was the only project that I’ve

They often award the physics prize for experimentally verifying a theoretical prediction. For example, they awarded the prize to Paul Dirac for predicting the existence of the positron, and to Carl Anderson for confirming it.

That lack of room for bias is a reasonable intuition, but at least one straightforward experiment contradicts it: "In a randomized double-blind study (n = 127), science faculty from research-intensive universities rated the application

This also prompted me to add my location in github. It would be interesting to see if there's a non-negligible difference to run this again in a few days, after everyone who gets word of it also adds in their location.

It would be nice if there were an easy way to hit the population center instead of geographic center of a nation in webgl-globe, at least. That big spike in the middle of Siberia puzzled me at first.

You can also use water for holding your pressurized structures together: bolt some pipes to your structure, bury them, pour liquid water through the pipes and into the soil, let it freeze, and you've got anchors made of ice.

Liquid hydrogen has what Elon Musk calls the pain-in-the-ass factor. It requires much higher volume tank at much lower temperature, adding lots of mass to the rocket, and it's impossible to effectively seal. RP-1 kerosene has the incon

One of the central costs of a round trip to Mars is the fuel for the return flight. With enough water at Mars we can manufacture all the methane/oxygen rocket fuel we need on site. The Mars Direct mission architecture and the NASA Joh

We can also electrolyze the water into oxygen and hydrogen for oxygen to breathe, and mix the hydrogen with carbon dioxide from the air to make methane, and use the methane and oxygen (or hydrogen and oxygen) for rocket fuel.
