  2. Levels in a book on Nature Publishes a "Post-Gutenberg" Electronic Text · · Score: 4, Interesting

    One area that's not often addressed or implemented is the concept of multi-leveled content. By this I mean that a traditional linear sequenced book conveys material mostly at one level of depth and proceeds sequentially. But I find for some material that a document that carries within it simultaneously beginner, intermediate, and advanced material can be useful. What I mean is that a reader proceeding sequentially through the book can choose treatments at the level suitable for them at the time and later come back and revisit at a deeper level, when they have enough background to understand deeper.

    I've taken one book I'm doing and split it into three volumes with hyperlevels like this. Volume 1 is a series of lectures exactly such as you'd get in a lecture hall. Volume 2 is readings to go along with the lectures to provide more material, and these exist as beginner, intermediate, and advanced hyperlinked items. The idea is that a student can get the basic background everyone should have in the domain, the more curious student can absorb the intermediate level treatments of the same topics, and the advanced student can be exposed to the fine points. While this could be done in a print book, it is easier to implement in a hypermedia form. The advantage of such a split-up approach is that it can deliver a volume of work without making the slower students have to plough through a dense and long path, they just need to tread the road they're given. (Volume 3 is a workbook and uses same approach.)

    However, a problem with such books is that with material fragmented so much and the structure not visible directly, it is harder for someone to grasp the overall structure of knowledge in the domain if they're first getting oriented. It's like a choose your own story book where you cannot see the overall story structure and could not speed read it easily, even if there is a linear table of contents.

    Issues with an e-reader are: 1) lecture board views and graphics just don't fit on a reader screen and are a pain to have to scroll around for students. 2) sometimes small screens just aren't enough. I'd like to see a video output port (do you hear me, Lab126 in Cupertino?) 3) sometimes it is really beneficial for students to be able to print pages and mark them up.

    I thank you for your wasted time replying. I am not trying to learn serious physics via Slashdot. Like anyone else using social media I'm merely looking for pointers, not a graduate seminar. Your candid and useless answer is appreciated in the spirit with which it was given, and in the same spirit, please investigate the effect of gravity on matter falling off bridges.

    Wouldn't the gamma ray sometimes get absorbed by matter, perhaps imparting momentum. Would this maybe be akin to the force of 'dark matter', since it would provide a force 'out of nowhere' on normal matter. So maybe the universe is expanding because of the very nature of the vacuum sea, being rectified / non-symmetric in this way. Kind of delivering something out of nothing, not in a mystical way either.

    I've never understood why the vacuum sea doesn't equally create as much anti-matter as it does matter. If it does, then why don't we observe constant energy bursts from collisions of antiparticles with normal particles? If doesn't, why would the vacuum sea be unsymmetrical? Either way, it doesn't seem to be reasonable.

    This discovery also illuminates another aspect of growth. Sure, you can build in a slice fashion, but obviously the initial full structure will not have full internal (neural) communications, because that can only be grown point to point AFTER the points are built. So this explains why infant maturing involves such massive neural growth. The building has been constructed, now the phone and IT infrastructure gets built up, over years. Plus, the building keeps getting improvements and expansions, so wiring has to be dynamically upgraded for the first 18 to 20 years. This also gives me some ideas for dynamic AI architectures, so whoo-eee! Fruitful discovery.

    That's correct in my experience.

Additionally, a former managerial co-worker was a horrendous sociopath (who brought the company down through his behavior) and he was in complete denial he had any problem. All issues were always the other guy's fault.

    Sociopathy has identifiable traits, it is destructive of others in many of its actions, and it is definitely a disorder.

  23. Re:An evolution from magnetohydrodynamics... on Pumping Fluid With No Moving Parts · · Score: 1

    Decades ago I discovered as a student (accidently in a chem lab) that you can pump dielectric and polar fluids without moving parts using a porous filter material (like ceramic) and a high voltage applied to the top and bottom surface. The flow rate is slow but it too requires no moving parts. Only modest current is needed at 800-900 volts.

    By using a shaped container around the filter to operate as a hydraulic lever, I imagine you could achieve higher flow rate in a narrow diameter tube, which might work for some applications like small actuators.

    I didn't patent it.

If you have any problems, click the "Ford Office' icon at the upper left corner being careful not to cause an accident in the process. Sometimes people outside may think you're giving them the finger, hahah. But our marketing department says 9 out of 10 people think this is cool to do 20 times a day, hahah.
