  1. Re:Last Post on Physicists Observe 'Negative Mass' (bbc.com) · · Score: 2

    In anti-matter universe, negative score predict you.

    Antimatter has mass. In fact, a given antiparticle has the same mass as its counterpart particle. Like, say, an antiproton and a proton.

  2. There's not much out there... on Ask Slashdot: What Are Good Books On Inventing, Innovating and Doing R&D? · · Score: 2

    I've taught a class on essentially this topic in a senior-level class for a couple of years at a top-10 US University, so I've performed this same search that you are (My day job is Research Faculty). I could find very little. This thread has some nice suggestions that I am definitely going to check out, though.

    Looking back now, I can see that in my own learning of the art of science and of R&D, it was all bits and pieces learned from people. Whether in undergrad, grad school, or as a post-doc – it was always the same case. I made a habit of listening to those whom I found competent. Most of the real, kernel-level things that I learned were discrete and small lessons. Sometimes a single observation or suggestion.

    I wish I could articulate something useful, but really it was the experience of working with others in science or R&D/engineering that I learned the most valuable lessons. Becoming competent in this skill-set is, as far as I can tell, best achieved by being an understudy – an apprentice. That is actually what graduate school is: an apprenticeship.

    I am not saying these things cannot be learned in other ways. If grad school is not an option, then read some of the fine-sounding books listed in-thread. Associate yourself, if you can, with anyone who possesses these skills.

    Good luck.

  3. It's useful on First Evidence For Higher State of Consciousness Found (neurosciencenews.com) · · Score: 4, Insightful

    Used responsibly, LSD is a phenomenal tool for introspection and "thinking about things from a higher plane". It's hard to describe to anyone who has not tried.

    Remove your consciousness from your life experiences, everyday minutia, your body's senses, and politics/history pegged to a timeline, and so on. Freed from these tethers, incredibly insightful things can be realized for the first time in the mind. After you come down, and you remember the experience, you will never view the world the same-old way again, but will process subsequent life experiences from an additional, fresh, and wholistic view-point. It is a marvelous eye-opener.

    Once you've "climbed the mountain" of a strong and positive LSD trip a few times, you will no longer need to take the drug to "get to that place", and to see things in this additional, new light. It is a breathtaking experience and changes your perspective forever. Well, for decades, at the least.

    * Pardon the slang and 'short-for' phrasing. I tried to make the point as concise as possible to anyone who hasn't tried it – an impossible task. *

    I assume the reason for this is Apple makes their money selling storage in the cloud. The more you use those apps, the more storage you need.

    There is no requirement to use anything iCloud to use these Apps. You can, if you wish, though.

    If you do, the price is in line with other cloud services. $2.99.mo. for 200 GB, for example.

  5. Re:Question for the Physicists. on Supercomputers Help Researchers Find Two New Kinds Of Magnets (phys.org) · · Score: 1

    I just don't get something about permanent magnets.

    A magnet exerts force, no?

    Exerting force requires energy, no?

    Where is the energy in a magnet? How is it obtained, stored, replenished?

    Magnets have a potential energy relative to a magnetic sample at any distance away, but the attraction falls off steeply, so you have to get close for the attraction to matter.

    Once you get close, the magnet's pull will be felt, and the object will be attracted to the magnet. Let it move closer (It's on a string), and potential energy between the pair is reduced. To reverse it, just pull the string, which takes force-over-distance, and so you have invested energy to pull the little sample away. Energy is conserved.

  6. Re:IBM PC on Ask Slashdot: What Was Your First Home Computer? · · Score: 1

    Hooray for the IBM PCjr! My father saved-up, and was either going to buy that or a Franklin (Apple IIe clone). PCjr it was.

    I learned to program on it by just going through the BASIC or DOS manual, finding new commands, and coming up with some way to use them.

    I made a program to play a polyphonic version of Moonlight Sonata, figured out how to use the three (four) display-type buffers to produce a Photoshop-like program that could save, open, and edit files in my own file format. Oh, and a few games and cartoon animations. God I miss that thing.

    My mother still has it. It's got a side-car and topper added-on to allow for what I think was 256 KB of memory, a 40 MB hard drive, and a serial interface that I was playing with to create a home-brew iTunes-like jukebox. Then I went off to college, but it's still there back at home. I'll set it up the next time I go.

    So, let's deliberately put water bears on Saturn to limit the risk to Titan and Enceladus? How can they be so sure that there isn't a layer of Saturn with composition, pressure, and temperature favorable to life?

    Aside from it being a gas giant, Saturn's huge gravity well will pull Cassini in hard and fast, vaporizing every little bit of it back into elements and simple compounds (like oxides of the metals). No bugs can survive this plunge.

    Storing digital on film negatives makes sense. At a bare minimum, it is equivalent ounce-for-ounce to a CD-ROM. That's if each pixel is binary. This is film we're talking about, with a huge dynamic range, so storing the digital with grayscale pixels to represent, say, hexadecimal values, increases the storage capacity by leaps and bounds without changing the weight of the medium.

    And, with a human-readable portion, instructions for interpretation of the pixels (digital data) are written on the media itself.

    All of this is covered by US Patent 8,085,304. Link to Patent, describing it clearly.

    The Earth still exerts a gravitational pull at orbital altitudes. They're not doing experiments outside of the influence of Earth's gravity, they're doing experiments in free fall.

    You were close. Because the unit was orbiting, it was not in "free" fall. Whatever the decay rate of its orbit, then that's the micro-gravity it was under (ignoring atmospheric braking).

    What's the difference between free fall and stable orbit? Well, hmmn, it's got to do with orbital speed and altitude. Take any satellite, like the ISS, and just stop its orbit, leaving it at the altitude it is. The earth's gravity will exert a noticeable effect on it – it will go into free fall.

    Difference without a distinction, almost.
