The Kline Directive: Technological Feasibility (1)

Posted by in categories: business, defense, engineering, military, philosophy, physics, policy, scientific freedom, space

To achieve interstellar travel, the Kline Directive instructs us to be bold, to explore what others have not, to seek what others will not, to change what others dare not. To extend the boundaries of our knowledge, to advocate new methods, techniques and research, to sponsor change not status quo, on 5 fronts, Legal Standing, Safety Awareness, Economic Viability, Theoretical-Empirical Relationships, and Technological Feasibility.

In this post I will explore Technological Feasibility. At the end of the day that is the only thing that matters. If a hypothesis is not able to vindicate itself with empirical evidence it will not become technologically feasible. If it is not technologically feasible then it stands no chance of becoming commercially viable.

If we examine historical land, air and space speed records, we can construct and estimate of velocities that future technologies can achieve, aka technology forecasting. See table below for some of the speed records.

Year Fastest Velocity Craft Velocity (km/h) Velocity (m/s)
2006 Escape Earth New Horizons 57,600 16,000
1976 Capt. Eldon W. Joersz and Maj. George T. Morgan Lockheed SR-71 Blackbird 3,530 980
1927 Car land speed record (not jet engine) Mystry 328 91
1920 Joseph Sadi-Lecointe Nieuport-Delage NiD 29 275 76
1913 Maurice Prévost Deperdussin Monocoque 180 50
1903 Wilbur Wright at Kitty Hawk Wright Aircraft 11 3

A quick and dirty model derived from the data shows that we could achieve velocity of light c by 2151 or the late 2150s. See table below.

Atlantica Undersea Colony — Undersea Colonization and Research

Posted by in categories: education, engineering, futurism, habitats, space, sustainability

It may have gone unnoticed to most, but the first expedition for mankind’s first permanent undersea human colony will begin in July of next year. These aquanauts represent the first humans who will soon (~2015) move to such a habitat and stay with no intention of ever calling dry land their home again. Further details: http://underseacolony.com/core/index.php

Of all 100 billion humans who have ever lived, not a single human has ever gone undersea to live permanently. The Challenger Station habitat, the largest manned undersea habitat ever built, will establish the first permanent undersea colony, with aspirations that the ocean will form a new frontier of human colonization. Could it be a long-term success?

The knowledge gained from how to adapt and grow isolated ecosystems in unnatural environs, and the effects on the mentality and social well-being of the colony, may provide interesting insights into how to establish effective off-Earth colonies.

One can start to pose the questions — what makes the colony self-sustainable? What makes the colony adaptive and able to expand its horizons. What socio-political structure works best in a small inter-dependent colony? Perhaps it is not in the first six months of sustainability, but after decades of re-generation, that the true dynamics become apparent.

Whilst one does not find a lawyer, a politician or a management consultant on the initial crew, one can be assured if the project succeeds, it may start to require other professions not previously considered. At what size colony does it become important to have a medical team, and not just one part-time doctor. What about teaching skills and schooling for the next generation to ensure each mandatory skill set is sustained across generations. In this light, it could become the first social project in determining the minimal crew balance for a sustainable permanent off-Earth Lifeboat. One can muse back to the satire of the Golgafrincham B Ark in Hitch-Hiker’s Guide to the Galaxy, where Golgafrinchan Telephone Sanitisers, Management Consultants and Marketing executives were persuaded that the planet was under threat from an enormous mutant star goat, packed in Ark spaceships, and sent to an insignificant planet… which turned out to be Earth. It provides us a satirical remind that the choice of crew and colony on a real Lifeboat would require utmost social research.

The Kline Directive: Theoretical-Empirical Relationship (Part 5c)

Posted by in categories: education, engineering, physics, policy, scientific freedom, space

To achieve interstellar travel, the Kline Directive instructs us to be bold, to explore what others have not, to seek what others will not, to change what others dare not. To extend the boundaries of our knowledge, to advocate new methods, techniques and research, to sponsor change not status quo, on 5 fronts, Legal Standing, Safety Awareness, Economic Viability, Theoretical-Empirical Relationships, and Technological Feasibility.

In this post I discuss the third and final part, Concepts and Logical Flow, of how to read or write a journal paper, that is not taught in colleges.

A paper consists of a series of evolving concepts expressed as paragraphs. If a concept is too complex to be detailed in a single paragraph, then break it down into several sub-concept paragraphs. Make sure there is logical evolution of thought across these sub-concepts, and across the paper.

As a general rule your sentences should be short(er). Try very hard not to exceed two lines of Letter or A4 size paper at font size 11. Use commas judicially. Commas are not meant to extend sentences or divide the sentence into several points!!! They are used to break up a sentence into sub-sentences to indicate a pause when reading aloud. How you use commas can alter the meaning of a sentence. Here is an example.

The Kline Directive: Theoretical-Empirical Relationship (Part 5b)

Posted by in categories: defense, education, engineering, philosophy, physics, policy, scientific freedom

To extend the boundaries of our knowledge, to advocate new methods, techniques and research, to sponsor change not status quo, on 5 fronts, Legal Standing, Safety Awareness, Economic Viability, Theoretical-Empirical Relationships, and Technological Feasibility.

In this post I discuss part 2 of 3, Mathematical Construction versus Mathematical Conjecture, of how to read or write a journal paper that is not taught in colleges.

I did my Master of Arts in Operations Research (OR) at the best OR school in the United Kingdom, University of Lancaster, in the 1980s. We were always reminded that models have limits to their use. There is an operating range within which a model will provide good and reliable results. But outside that operating range, a model will provide unreliable, incorrect and even strange results.

Doesn’t that sound a lot like what the late Prof. Morris Kline was saying? We can extrapolate this further, and ask our community of theoretical physicists the question, what is the operating range of your theoretical model? We can turn the question around and require our community of theoretical physicists to inform us or suggest boundaries of where their models fail “ … to provide reasonability in guidance and correctness in answers to our questions in the sciences …”

Today, a Young Man on Acid Realized that all Matter is Merely Energy Condensed to a…

…here’s Tom with the Weather.
That right there is comedian/philosopher Bill Hicks, sadly no longer with us. One imagines he would be pleased and completely unsurprised to learn that serious scientific minds are considering and actually finding support for the theory that our reality could be a kind of simulation. That means, for example, a string of daisy-chained IBM Super-Deep-Blue Gene Quantum Watson computers from 2042 could be running a History of the Universe program, and depending on your solipsistic preferences, either you are or we are the character(s).

It’s been in the news a lot of late, but — no way, right?

Because dude, I’m totally real
Despite being utterly unable to even begin thinking about how to consider what real even means, the everyday average rational person would probably assign this to the sovereign realm of unemployable philosophy majors or under the Whatever, Who Cares? or Oh, That’s Interesting I Gotta Go Now! categories. Okay fine, but on the other side of the intellectual coin, vis-à-vis recent technological advancement, of late it’s actually being seriously considered by serious people using big words they’ve learned at endless college whilst collecting letters after their names and doin’ research and writin’ and gettin’ association memberships and such.

So… why now?

Radioactive Pollution: Fishing for Answers off Fukushima

Posted by in categories: engineering, nuclear energy, policy, sustainability, treaties

A recent article in Science Daily reported on efforts to measure Cesium-137 and Cesium-134 in bottom dwelling fish off the east coast of Japan to understand the lingering effects and potential public health implications. As the largest accidental release of radiation to the ocean in history, it is not surprising that many demersal fish are found above the limits for seafood consumption. What is more significant is that the contamination in almost all classifications of fish are not declining — suggesting that contaminated sediment on the seafloor could be providing a continuing source. This raises a concern that fallouts from any further nuclear accidents would aggregate over time.

One would question if the IAEA is taking a strong enough position on the permitted location of nuclear power stations. It perplexes me that the main objections to Iran attaining nuclear power are strategic/military. Whilst Iran is not at risk to the threat of tsunamis as Japan is, Iran is one of the most seismically active countries in the world, where destructive earthquakes often occur. This is because it is crossed by several major fault lines that cover at least 90% of the country. How robust are nuclear power stations to a major quake? The IAEA needs to expand its role to advise countries on what regions it would be unsuitable to build nuclear power stations — such as Iran and Japan. Otherwise we are risking a lasting environmental impact to eventually occur — it is only a matter of time.

How the Diablo Canyon nuclear plant, which sits just miles away from the notoriously active San Andreas fault was allowed to be located there let alone operate for a year and half with its emergency systems disabled (according to a 2010 safety review by the federal Nuclear Regulatory Commission). It seems as if there’s a missing link worldwide between the IAEA and regional planning authorities. Or perhaps it is simply down to responsible government.

The Kline Directive: Theoretical-Empirical Relationship (Part 4)

Posted by in categories: business, cosmology, defense, economics, education, engineering, nuclear weapons, particle physics, philosophy, physics, policy, scientific freedom, space

To achieve interstellar travel, the Kline Directive instructs us to be bold, to explore what others have not, to seek what others will not, to change what others dare not. To extend the boundaries of our knowledge, to advocate new methods, techniques and research, to sponsor change not status quo, on 5 fronts, Legal Standing, Safety Awareness, Economic Viability, Theoretical-Empirical Relationship, & Technological Feasibility.

In this post I have updated the Interstellar Challenge Matrix (ICM) to guide us through the issues so that we can arrive at interstellar travel sooner, rather than later:

Interstellar Challenge Matrix (Partial Matrix)

Propulsion Mechanism Relatively Safe? Theoretical-Empirical Relationship?
Conventional Fuel Rockets: Yes, but susceptible to human error. Known. Theoretical foundations are based on Engineering Feasible Theories, and have been evolving since Robert Goddard invented the first liquid-fueled rocket in 1926.
Antimatter Propulsion: No. Extensive gamma ray production (Carl Sagan). Issue is how does one protect the Earth? Capable of an End of Humanity (EOH) event. Dependent on Millennium Theories. John Eades states in no uncertain terms that antimatter is impossible to handle and create.
Atomic Bomb Pulse Detonation: No, because (Project Orion) one needs to be able to manage between 300,000 and 30,000,000 atomic bombs per trip. Known and based on Engineering Feasible Theories.
Time Travel: Do Not Know. Depends on how safely exotic matter can be contained. Dependent on a Millennium Theory. Exotic matter hypotheses are untested. No experimental evidence to show that Nature allows for a breakdown in causality.
String / Quantum Foam Based Propulsion: Do Not Know. Depends on how safely exotic matter can be contained. Dependent on a Millennium Theory. String theories have not been experimentally verified. Exotic matter hypotheses are untested. Existence of Quantum Foam now suspect (Robert Nemiroff).
Small Black Hole Propulsion: No. Capable of an End Of Humanity (EOH) event Don’t know if small black holes really do exist in Nature. Their theoretical basis should be considered a Millennium Theory.

It is quite obvious that the major impediments to interstellar travel are the Millennium Theories. Let us review. Richard Feynman (Nobel Prize 1965) & Sheldon Lee Glashow (Nobel Prize 1979) have criticized string theory for not providing novel experimental predictions at accessible energy scales, but other theoretical physicists (Stephen Hawking, Edward Witten, Juan Maldacena and Leonard Susskind) believe that string theory is a step towards the correct fundamental description of nature. The Wikipedia article String Theory gives a good overview, and notes other critics and criticisms of string theories. In What is String Theory? Alberto Güijosa explains why string theories have come to dominate theoretical physics. It is about forces, and especially about unifying gravity with the other three forces.

The Kline Directive: Theoretical-Empirical Relationship (Part 3)

Posted by in categories: cosmology, defense, education, engineering, particle physics, philosophy, physics, policy, space

To achieve interstellar travel, the Kline Directive instructs us to be bold, to explore what others have not, to seek what others will not, to change what others dare not. To extend the boundaries of our knowledge, to advocate new methods, techniques and research, to sponsor change not status quo, on 5 fronts:

1. Legal Standing. 2. Safety Awareness. 3. Economic Viability. 4. Theoretical-Empirical Relationship. 5. Technological Feasibility.

In Part 1, we learned that Einstein was phenomenally successful because his work was deeply meshed with the experimental evidence of the day. In Part 2, we learned that to be successful at developing new useful theories and discovering new fundamental properties of Nature that will bring forth new interstellar travel technologies, we need to avoid hypotheses that are not grounded in experimental data, as these are purely mathematical conjectures.

In my book on gravity modification I classified physics hypotheses and theories into 3 categories, as follows:

From Part 1 … “that mathematics has become so sophisticated and so very successful that it can now be used to prove anything and everything, and therefore, the loss of certainty that mathematics will provide reasonability in guidance and correctness in answers to our questions in the sciences”.

We need to note that there are several different relationships between the mathematics of physics and the physics of the real world.
