  1. Re:Modern Fortran on A C++ Library That Brings Legacy Fortran Codes To Supercomputers · · Score: 1

    but many more languages are now more common that Fortran, and most newly created code is C++ and often wrapped by other languages such as python.

    x86 most modern?, it may well be. You do realize that x86 processors don't have internals that represent the instruction set (unlike processors of decades ago), it is more accurate to say they emulate the x86 via microcode. The internal architecture is extremely advanced even if the x86 memory and register model is a not a linear clean and orthoganal design.

    . England has enough data for wonderful statistics for deflators over huge timespans, for instance from 1860 to 2012 we have 100 times price factor. http://safalra.com/other/historical-uk-inflation-price-conversion/ And from 1490 to 1860 about nine point seven food price factor.

    I don't either, I've stocked up on lead solder for electronics and plumbing to last a lifetime. No need to worry about lead contamination either, it won't happen the way hardened solder ages. Not even in plumbing with one very important exception that doesn't apply where I live. if your water has small amounts of salt in it, and it goes through pipes with lead solder, you're screwed. just a PSA for those of you in say Houston or other places where ocean water gets into your drinking water a bit

  15. Re:space & time as emergent properties on Physicists Discover Geometry Underlying Particle Physics · · Score: 1

    in that view, matter an antimatter aren't really meeting and annihilating and making photons, it's just an electron meeting a photon and both bounce backward in time. The photon is its own antiparticle so it looks the same going forward or backward in time, but the electron is a positron going backward. Thus we see an electron and positron meet and two photons fly away.

    Now add that to your view of interactions and time, and the universe gets very simple and nearly empty

  16. Re:space & time as emergent properties on Physicists Discover Geometry Underlying Particle Physics · · Score: 1

    I would only add that Feynman wondered if there was really only a single electron in the whole universe, with "an extremely complicated world line" going back and forth in time, and it is a positron while going "backward" in time. This explains why all electrons are identical, they're the same one.

    Nothing nonsensical about your musings, the greatest minds in physics have wondered about such things.

    Actually, light weight nucliei are better for shielding in space because much less secondary radiation produced. The slower protons cause more damage than the high energy ones which pass through the body without time to interact.

    No need to recreate an "earth's magetosphere", there are alternative designs such as having opposing strong fields that in the center of the ship where the crew is the field intensity is low. Also combined electrostatic and magnetic designs. Quite an engineering problem though.

    Plenty of explorers and experimenters have died too. For example, how did we learn certain plants are poisonous?

There are worse ways to die and more useless ways to die than after exploring in space. In the time it took you to read my post some people choked to death on tough food, some were run over by cars, some were gunned down by street punks, some fell into a hole and died, some died of flu, etc. etc. etc.

    cancer not an issue, the radiation levels are lethal by the outright mass death of cells.
