Halting Problem Proves That Lethal Robots Cannot Correctly Decide To Kill Humans

clonan Re:Quantum Mechanics and Determinism (317 comments)

Why not? This is the best possible case.

The argument in the original article is that a Touring Machine is limited by the data available to it (even if that data is infinite). This means that the TM can't make a "judgment" because it will always find the same result based on the data provided by the programmer.

QM based randomness means that "new" data is added to the system and the system must now accommodate this new and unpredictable scenario. It is the ability to analyze "new" data that allows for judgment.

Halting Problem Proves That Lethal Robots Cannot Correctly Decide To Kill Humans

clonan Re:Quantum Mechanics and Determinism (317 comments)

Computers spend a LOT of power to eliminate the randomness. In-fact randomness is defined as an "error" in the typical computer and generally frowned on by the end user.

In addition we are talking about a Touring Machine which is a thought experiment and therefore not really subject to the laws of the universe..

Halting Problem Proves That Lethal Robots Cannot Correctly Decide To Kill Humans

clonan Re:Quantum Mechanics and Determinism (317 comments)

Actually no, I am stating that the human brain is NOT a Turing Machine and can never be a Turing machine therefore any attempt to correlate the original article with "human judgment" is fallacious.

I did say that while I don't know for sure, the ability to integrate and question the randomness inherent in the Universe COULD provide a method of providing a truly independent judgment.

To answer your questions:

No, if you feed a human being the same information twice you often will NOT get the same response even when the person has no ability to remember (say through brain damage). For a fun image think of the movie "50 first dates". Now obviously the simpler the question the more likely you will get the same response, however when you have complex questions you start to get divergent answers. Agreed they do tend to be similar but not identical.

Remember the randomness affects everything and will end up having a large number of effects that will average out to an apparent deterministic system unless tested carefully.

Read the definition of a Turing Machine. They are absolutely deterministic.

Halting Problem Proves That Lethal Robots Cannot Correctly Decide To Kill Humans

clonan Re:Quantum Mechanics and Determinism (317 comments)

My original post was simply pointing out that the human brain is NOT and can never be a Turing machine due to the fundamental randomness of the universe. This means that no study of Turing Machines can make any claim on human judgment calls.

I am not sure the random nature of the universe is sufficient to allow for true 'judgement' but it MIGHT.

clonan Re: Quantum Mechanics and Determinism (317 comments)

My admittedly limited understand is that the randomness is a fundamental requirement of the theory.

I find QM interesting and have read up on it but I am certainly not a theoretical physicist...

http://en.wikipedia.org/wiki/Quantum_mechanics/

I know wikipedia but I am lazy and don't really care...

Check out "During a measurement, on the other hand, the change of the initial wavefunction into another, later wavefunction is not deterministic, it is unpredictable (i.e., random). A time-evolution simulation can be seen here.[28][29]"

There are two cited references.

A large number of quantum particles seem to act in a deterministic way but this is simple the law of large numbers.

Please tell me exactly when a specific electron is 14 billion 123 million 567 thousand 324 years and 23485723048752 seconds after the big bang...

You CAN'T!

It isn't just knowing the starting conditions it is about being able to calculate every state between the beginning and the end.

clonan Quantum Mechanics and Determinism (317 comments)

The problem with Turing machines is that they are by definition a deterministic system. A certain input will give a specific output. That is why they can't make a "judgment" call.

The universe as a whole is NOT deterministic as Quantum Mechanics proves. QM is based on true randomness (obvious a simplification but go with it for this conversation). Our 'machines' deal with this randomness and even incorporate it into some operations. So a specific input will NOT always generate the same response.

It is the assessment of random changes that MIGHT give us the ability to make these sorts of judgments....

secondary reactions based around contaminants (as in non-H or He atoms).

One is the CNO cycle which is about 0.4% of the total solar energy.

Study Linking GM Maize To Rat Tumors Is Retracted

clonan Read the definition of corn... (341 comments)

Gan: Corn is defined as a small hard grain/seed

Wheat is corn
Rice is corn
Rye is Corn
Millet is Corn

Maize is also corn

The term Corn used in supermarkets is actually slang....

If you are going to be a vocab critic then at least get the vocab right!

A War Over Solar Power Is Raging Within the GOP

clonan Re:Keystone Pipline (1030 comments)

As I mentioned in my original post, MOST of the value comes from legal protection and eminent domain land purchases.

For example, Bush's Energy law included a provision that prevents anyone from suing gas station owners from leaks that have contaminated local communities. This one provision is worth hundreds of billions and doesn't show up on the federal budget.

Most of the direct benefit actually comes from tax breaks which don't show in the budget.

Most of the real cost is not directly related to DIRECT subsidies. Most of the benefit comes from repairing the damage these energy sources do to health and environment. Look at how much the EPA spends to clean up oil related environmental damage.

Next, the federal government is not the ONLY source of subsidies. States provide roughly equivalent subsidies.

Finally, you say my number is crazy??? The EU countries also subsidize oil but no where near as much since they also tax the final product... The EU fuel cost is around $9 a gallon...

A War Over Solar Power Is Raging Within the GOP

clonan Re:Why subsidize? (1030 comments)

We should be encouraging:

1. Thorium nuclear - Difficult to weaponize, readily available fuel, reduced waste, economically viable in smaller reactor sizes
2. Other Nuclear - Regional fuel access, proliferation issues
3. Solar - Can use "dead" space (like rooftops) which reduces NIMBY issues
4. Wind - more limited in location and NIMBY issues

A War Over Solar Power Is Raging Within the GOP

clonan Keystone Pipline (1030 comments)

Umm, what about the Keystone XL Pipeline... That single project is receiving between 1 and 1.8 BILLION dollars in subsidies.

For reference ALL renewable received $5.93 billion.. over a 15 year period...

Plus the real benefit that oil, coal and natural gas receive are liability protection from spills, poisoning etc plus eminent domain lad purchases for pipelines etc.

These issues are not represented in the typical accounting of subsidies and easily doubles the value.

I remember reading that is all benefits were removed from oil than the price of gas would be between 12-15 dollars a gallon!

Bradley Manning Sentenced To 35 Years

clonan 20 Counts (491 comments)

He was charged with 20 counts NOT 10,000. Prosecutors don't need to read all 10,000 they only needed to read 20.

Just because you kill someone in self defense doesn't mean that you can kill anyone you want.

Even if 9,880 documents are evidence of war crimes, he is still guilty of releasing sensitive information the SHOULD be kept secret.

Moore's Law and the Origin of Life

clonan Read up on Histones (272 comments)

Not true. Histones, the proteins that keep DNA ordered, are some of the earliest proteins. They provide an extremely accurate clock for when species diverged.

While on a short term, a few million years, you are right when you say the rate of genetic drift is not predictable. However, over a longer period of time the rate SEEMS to be fairly consistent. That is the point of the article.

You seem to be confusing genetic diversity with Phylogenetic diversity. Phylogenetic diversity describes how genes change physical differences while genetic diversity talks about the complexity of the genes themselves.

You can have genetic diversification without the physical structure of the organism changing, especially if there are environmental restrictions.

IBM Creates 'Breathing' High-Density Lithium-Air Battery

clonan Electric Drive Train? (582 comments)

You are assuming that EV will simply replace the current engine and fuel tank with an electric engine and battery... This is not what has to happen.

Currently engines are big and heavy so you only have one. You then have to transfer the rotational energy of the engine to the wheels. But Electric motors are very light and tiny. So why not have 4?

Put a small electric engine in each wheel and you eliminate the entire drive train... no more drive train losses and EV's are back up to 90%.

Your 72% efficiency only applies to ICE cars that have been converted to EV's.

Kepler Confirms Exoplanet Inside Star's Habitable Zone

clonan Re:Take that... (257 comments)

Direct observation of quasars and other celestial objects.

We can deffinetivly identify the direction of rotation of pulsars as well as a variety of other objects with accretion discs. From these observations we have determined that from our perspective, the orbital plan is esssentially random.

Since we know that angular momentum is conserved, it is safe to assume that the original stars that formed these objects had a random distribution of orbital plans relative to us.

Since we know stars have a random distribution of orbital plans, it is safe to assume that the planets round thoes stars do as well...

All based on direct observation.
