Comment Re:Of course science can't prove God. (Score 1) 755

You can not have something that is omnipotent.

Is that an axiom or can this statement be proven?

so it has no effect?

The effects of an omnipotent entity can be as detectable or as undetectable as the entity wishes.

Really, if it changes something that CHANGE is detectable even if you can't see what is causing it.

If you can't think of at least three ways an omnipotent entity could mess with your detection, then you have no imagination.
Can you detect the actions of a root user on a system where you don't have root privileges yourself (and no access to the hardware)? We have discovered many thing we only initially knew because of there effect on something else, like planets.

Planets aren't omnipotent entities.

Also, please learn what entropy is. There are about a dozen different meanings. I'm referring to thermodynamic entropy.

So you think it is possible to freeze a drop of water without increasing the thermodynamic entropy of the universe?

Omnipotence trumps science any day. Something that is omnipotent can chose to remain undetectable to science. Even something that can ignore the laws of thermodynamics (a subset of omnipotence) could do so.

On the other hand, even the tiniest effect that ignores the laws of thermodynamic can be taken as proof of god-hood. If any entity can freeze even a drop of water without increasing the universes entropy, it should be considered a god for all intents and purposes.

In learning school, the people of my tribe were taught that molecules ARE matter.

Atomic nuclei are matter. Disassembling and reassembling atomic nuclei, however, is an entirely different beast (several orders of magnitude difference in energy) than disassembling and reassembling molecules.

I love the space elevator/beanstalk idea, but we're several human generations away from the first full-scale model.

Which is why we should stop dreaming about it and stark working on things that are feasible with our technology. Mass drivers, launch loops, laser propulsion, you name it.

Venus won't be of much use until we can disassemble and reassemble matter itself.

Actually, we don't need anything that exotic (matter generation) for starters. We need a universal chemical synthesizer, which can assemble chosen molecules from a set of given input compounds. Basically a very flexible chemical plant. It doesn't need to create matter, just rearrange given molecules into new molecules.

After Luna and Mercury, there will be very little use of the other planets, other than small moons.

I disagree.

Planets are just too darn hard to get on and off of.

Only if you use primitive launch technologies which require the ascent vehicle to carry all of the necessary energy and reaction mass for the ascent.

Seriously, you think that in your scenario, we'll still use rockets as the main way to get off planets?

The first thing we need is one or more ways to launch things into space where most of the energy and reaction mass is not carried by the launch vehicle.

None have proper gravity or pressure for us.

Venus could be cooled down with a solar shade in space (which could double as a power plant) and be transformed into something more habitable than its current state.

Also, some applications work in a wide range of gravity. You can have fairly normal kitchens, bathrooms, swimming pools, showers, sinks and toilets on Mars, despite only having a third of the gravity of Earth.

Comment Re:Solar irradiance in the article? (Score 1) 200

Why did you make the parent comment specifically stating the opposite?

Err, I didnt?

The correct relationship is an inverse-square-distance (1/(d^2)) relationship. Compared to Venus, Earth is about 140% of Venus' orbital radius from the sun (and therefore gets 1.4^2 the solar irradiance) and Mars is about 240% farther from the sun (and therefore gets 2.4^2 the solar irradiance).

The numbers in the article give an inverse (not squared) relationship, which would be correct for distances, but not for solar irradiance.

Comment Re:C is very relevant in 2014, (Score 1) 641

Hmm... upon reading my comment, I realize that C *IS* guides

C doesn't really guard anything. It does keep you from having to roll your own multiword arithmetics or integer division algorithms, and from dealing with architecture-related things that are mind-boggling for a human, but just another set of rules to a compilers (pipelines, delayed instructions, etc.), and takes over things like optimizing register usage.

On a computer, all the guides come at the cost of performance. Sure, you can make a programming langugage where buffer overflows are alway caught, but that language will spend a lot of CPU cycles on checks.

Comment Re:Very relevent for small target embedded stuff. (Score 1) 641

BS. Embedded development still happens on 8-bit controllers

And there's also plenty of ARM chips that don't run Linux (because they can't due to lack of a MMU), e.g. Cortex-M0...M4-based parts.

That's one of the nice things about small target embedded work. It covers everything from 8-bit to 32-bit, from simple (no hardware multiplier, no division in hardware) to loaded (hardware floating point support, MAC units, HW dividers), from slow (temperature logging) to fast (control loop running at 30 kHz requiring 3us latency).
