    You're right. They should have scholar.google.com locked up in a testlab, accessible only to google employees. until they iron out ALL the bugs. That's far better than to let all acedemia use it right now for the benefit they could recieve using it.

    As should be obvious, I think you're nuts. I've used google scholar for projects at uni for a while now, and it has been quite usefull. It could be better (direct display of homonyms...you never know what jargon scientists will use for the same bloody phenomenon), but it's usefull in it's current state. I'm far happier being able to use it now. If they want to call it beta, fine for them.

    WinCe/mobile has PalmOS beat on one thing only; natural handwriting recognition.

    You should know though (apparently having had a treo) that palm supports word/excel better than win mobile does. Formatting, saved files etc. It's a well known irony that palm does better than MS at it's own format.
    All the rest you mention...palm does that too, effortlessly (although why you'd want to read stuff in .lit I really don't know).

    "but when it comes to my PDA it has to just work and it is for getting serious work done quickly."

    So get a palmOS device (or, what I'd want now is a win mobile device with palmOS on it :))! When my friends and I get into the old 'my pda is better than yours' arguments, I do this: we "race" to see who can a)set up an appointment faster b)who can draw an annotated map faster in the app of users choice c)see who can dictate a word faster and d)find a contacts email faster.
    A palmos device wins at all of 'em.

    Oh...and another nice thing is to see which device can play it's mp3's the longest (through headphones, to make it more objective) :)

    And wtf is that 'closing an app doesn't really stop the thread from running' crap which win mobile still pulls? I click close and my damn app better remove itself from memory unless I don't want it to (as is the case for when I run my mp3's when reading)...

    The only things win mobile does right is handwriting recognition, the hardware and slightly easier appwriting. But for basic PDA functionality palmos wins every time.

  4. Re:Rapid prototyping, etc on Fab · · Score: 1

    "but allowing low cost R&D"

    Too true. In Delft, a professor working on quantum representations of electronic circuits told me the following: it takes them 3 months to get a chip from a fab. Sometimes the chips are flawed...so there go another three months. Sometimes everything is correct, but the circuit still doesn't do what it's supposed to; a quick modification to the design...and another three months worth of waiting. Not to mention the expense! A different group in the faculty is working on systems using electron beams to create chip prototypes...but that's a slow way of doing things (but cheaper than making chip-masks).

    There is still one mayor problem with 3d rapid prototyping systems though; the rasterisation leaves you with a part which needs to be finished (meaning there are always steps between the lower and higher layers; you won't get a smooth surface...kinda like a lego pyramid before they had anything other than plain blocks; it's an artifact from the stepping of the deposition motor and the fact that most 3d prototyping systems have to work in discrete layers).

    So when you say rocket motors, am I correct in assuming that you mean just the laval tube? Depending on the exact geometry, I wouldn't be surprised if finishing the actual protoype's surface is a part of the problem. Stepping problems (the lego effect) don't appear in traditional metal fabrication like milling, turning, extrusion or moulded parts, but I bet the inherent metal structure which results from 3d protoyping also makes for some interesting stress calculations. Add to that a difficult finishing process which could also affect the structure of the tube and I'm not surprised 3d prototyping a laval tube is difficult.

    Then again, it could be that a)you mean the entire motor (?!) and b) these are absolutely not the difficulties you've faced :)

    I know...currently they use ESA and Sea Launch for their space trucks more than the shuttle due to lower costs, but sometimes they need the extra capacity the shuttle can provide.
    I use the term space truck for any launch vehicle who's job it is to just deliver payload into orbit...much like a truck delivers cargo to an earthbound destination. And seeing the amount of satelites launched (appart from the fact that yeah, it's in space, it's more dangerous, and it isn't routine) I would call it a space-trucking business...now all we need is a true space truck (as pertaining to cheap launch costs).

    I think I do get what you're getting at :) That's kinda why I mentioned Rutan, even though I know what he's doing isn't what you mean, at least he's getting there in terms of a fully re-usable first stage and a second stage which doesn't need to fly up but just has to deal with re-entry. Sure, he doesn't go orbital, but he is seperating launch stages into discrete stages which are designed to perform in their seperate environments.

    What's interesting is what Rutan is planning after his next launcher: orbital in seperate re-usable stages. SS1 and WK are just neccessary steps in the production process.

    Is a bachelor in applied physics enough? Please remember we're launching from the ISS, not earth.

  9. Re:The Only Things? on Space Shuttles almost Ready to Re-Launch · · Score: 1

    I'm aware of the physics of the situation. Which is exactly my point. Speed is not very important. No resitance means that (barring the gravity the ISS causes) your launch speed can be mere meters per second: the trash'll get there and doesn't have a reason for having to get there fast. Only when you shoot for re-entry burnup do you need a specific speed in order to miss satelites...and we can calculate their positions just fine, so I'd guess that low speeds would suffice even for that option.

    As for the second part: think mass production. Think multiple microsats on one launch. Optimal vehicle designs only mean something if you have the money for it...point being that if you can build that re-entry vehicle cheaply enough, and keep launch costs low (which for a standardised, mass-produced vehicle is a pretty expectable thing), you design the payload to work with such a vehicle. That's how mechanical engineering for mass-production works: look at Ford. Look at tank production in WWII. Look at the Joint Strike Fighter: at least three designs on the same superstructure, translating into less money spent than if we'd done three seperate vehicles.
    If you can get people and cargo into orbit, you're there. What, your cargo needs people to deploy it? No problem, we'll send two of the cheap ships, one with a crew module, one with the cargo...and that's feasable because both vehicles (appart from the cargo/crewmodule) are the same and we have built a hundred of them. Oh, you'r cargo need to be launched into orbit and then retrieved? We'll outfit a retreival arm into the cargo container. Different orbit? Again...we'll just fill this ship up to here with fuel...the extra fuel costs due to un-optimal fueling/vehicle design will be lost against the savings we have made by designing just the one superstructure instead of designing three different ships from scratch.

    Now I'm not saying all differentiation in launch vehicles is bad/dumb/whatever. I'm just saying that for getting people/cargo into space, one all purpose, retaskable vehicle will save money. What I'm saying is take a space shuttle and strip it bare untill you have a launchplatform. Then add space to add either a cargo module, or a crew module, or a hybrid, or whatever. You'll end up with a ship which is more versatilke than the shuttle for a fraction of the cost. I mentioned the tanks and the JSF before...also look at what general motors and other car companies want to do with electrical/hybrid cars, or what they're already doing with modern-day cars: they're using a common base and differentiating from there (plug in an engine, a chassis and an interior onto the base, and you have a new model car). They do this because it makes sense: it reduces cost and makes different designs (from that common base) easier, cheaper and faster.

    Trash is not a problem. It is (in orbital terms) trivial to eject trash in such a fashion that it would either hit the sun, crash onto the moon or burn up on re-entry.

    The rest (crew/experiment return) could be handled with what the Hermes was supposed to do. Burt Rutan has shown that the concept works.

    When you think about it, there's only two (maybe three) vehicles needed, and they could concievably be unified in one design: crew transport, cargo transport and satelite transport.
    I say just design a re-usable launch vehicle that can transport one standard shipping container (the ones they use to ship freight on boats) and all you have to do is design a container for each kind of launch...

    Oh, come on! your position is indefensible...give in!

    'the Shuttle has a very good safety record for what it does' This means getting crew, orbiter and payload into orbit and getting the crew and itself safely back. That's the only thing it can mean and that is what it does mean. The shuttle cannot be controlled remotely (unlike it's never-flown russian counterpart!). So any comparison to a non-crewed launcher is flawed.

    "It is not essential for humans to be in the spacecraft to deliver payloads."

    True....but only humans at this point can give neccessary feedback and handle unforseen circumstances...which are bound to come up when your talking about a frontier field like space flight. Even with our current state of the art robotics we'd not have seeen apollo 13 back. Your point that 'if it had been a robot, no-one would have cared' is beside the point: schumacher-levy has adequately demonstrated that it's insane to have all our eggs in one basket.

    Which makes me wonder, especially that last bit, "why?".

Now I know that creating a bearproof suit isn't really credentials...but it worked (and was proved to do so...he got himself attacked by a bear and he survived without a scratch), but apparently there was quite the industry interest in the coating...especially because it was cheap to manufacture and 'made from simple items...you wouldn't believe what it's made of!'.

    So what I wonder is this: with the amounts of research having gone into material science and thermodynamics, why is the shuttle still using the most innefficient method available? In the thirty years since, there must be some better way of thermal protection than the oh-so-labour-intensive-each-block-custom-made-and- only-fits-there method they still use...

    BTW:
    "Honestly, I feel sorry for the people who signed off on the safety of the Columbia launch: every other safety board in the shuttle's history, including those during the ones early in the Shuttle program."
