   All of the "big" Forth systems come with some sort of standard library. In the open source world, gForth [1] is pretty well-known which comes with a comprehensive set of words [2] many are not part of the ANS Forth standard [3,4].

   AFAIR here in Germany you pay about .05 €/kwH power transmission fees that go to the owner of the transmission infrastructure (i.e. "the grid"). I wonder how much people in the US pay. You get what you pay for :)

   I think you need to factor in the costs incurred by building and maintaining high voltage power transmission lines. These have to be payed for by users of the power grid. If you go off grid, then you not only reduce transmission losses, y

   I think most of the losses are due to the cost of building and maintaining transmission lines. These have to be paid for by users of the power grid. In Germany these transmission costs constitute about 20% of the total end-user price per

   I think we have a lot of theory about turing-complete computation. I really wonder why somebody would be willing to sign a turing-complete contract? The problem of understanding properties of the contract may be NP-hard [1] i.e. practical

   First thing I thought, when reading the linked article: "Oh my god". This is extremely bad. Think what would happen if you deployed RSA with 256-bit keys for HTTPS and SSH (for host and user key-pairs). If the results reported

   Japan has a surprisingly ambitious space exploration program, much of which seems to go completely unnoticed by the west. At about 2e9 $/year (about 1/10 of the founding NASA gets) they've successfully launched: * a solar sa

    Quasi-particles are not just math. They have measurable properties that are like properties of real particles (just like "holes" in P-type semiconductors can be measured to behave like quasi-positrons). Or, replying to your prop

    I only skimmed the article, but claiming discovery of a "new particle" seems extremly bogus. According to wikipedia [1], the cited paper merely demonstrates the finding of a quasi-particle [3] that behaves like a Weyl Fermion. Cl

    BTW most of what I know about black hole physics is from Greg Egan's novel "Incandescence". Which covers quite a lot of science for a work of fiction (and overall extremely inspiring). http://gregegan.customer.net

    Somewhat related: there is a short story by Greg Egan, "The Planck Dive", describing a voyage (without return) into a black hole, in a scientifically not too absurd way. You can read it online: http://gregegan.customer
