  • A Chinese show has already been released and an American one is releasing on Netflix soon. The Chinese version can be streamed on Viki. I’m about 1/3 of the way through (30 episodes) and I’m absolutely loving it. They don’t dumb down any of the details with the science and is staying very true to the books so far. You just have to be willing to watch a subtitled show

    I’m happy to be surprised but I doubt I’ll like the US version as much. Nearly every US book adaptation I’ve watched has been dumbed down “for a wider audience” and changed quite substantially (looking at you, Silo and Beacon 23). This is also coming from D and D of GoT infamy, so we’ll see if they can turn their track record around. At least this book is finished so they have the entire source material to work with


  • During the day it’s white, but it’s also overhead and blindingly bright so we don’t spend much time looking at it. As it gets closer to the horizon Rayleigh scattering begins filtering out the bluer light and the sun becomes yellow, then orange, then red. It also gets closer to our eyeline and becomes mildly safer to look at so we look at it a lot more. This in turn leads us to believe it’s always yellow




  • Red is light at the 480 THz range. Blue is light at the 670 THz range. I think that’s perfectly described using terms of the physical world. If you’re talking about “what we experience as color” as being difficult to describe in our consciousness, then sure but that’s the case for every single thing we experience. Same way I can describe the musical note A as 440 Hz. Does an A to you sound the same to me? My tongue is sensing a sugar molecule, does the experience of tasting it feel the same to you?

    Not a single human perception can be described in words, but we can all compare perceptions to other perceptions and agree on the same answer. Perceptions are simply us recognizing patterns in our environment. Red is me recognizing my eyeball is looking at an object reflecting light in the 480 THz range. You look at that red ball and you also recognize it as reflecting light at 480 THz. Does it need to be described any further?



  • Home generators are not very efficient, they lose a lot of energy to heat and noise. It’s close to the break even point so depending on your generator and heatpump, you could use more gas than with a modern gas furnace. Even with a theoretical perfect 100% efficient generator, it’s not going to be an order of magnitude less gas because heat pumps are not 1000% more efficient than a gas furnace
