Smithsonian National Air and Space Museum: No Lifeboats Please

Posted by in categories: defense, education, engineering, existential risks, finance, military, space

It was on a long-haul flight many months ago that I recalled a visit to the National Air and Space Museum [1] to a fellow passenger whom I struck up conversation with. Asking if I could recommend somewhere to visit in Washington DC, I recounted how I had spent an entire day amazing at the collection of historic aircraft and spacecraft on my only visit to that city fifteen years or so previous as a young adult — and as always a kid at heart.

Seeing the sheer scale of the F-1 engine for the Saturn 5 rocket first hand, stepping inside an Apollo command module identical to those used during the Apollo program, not to mention seeing full life-size replicas of the Lunar Roving Vehicle, an Apollo Lunar Module and for some reason what seemed most surreal to me… the Viking 1 Lander. This was enchantment.

However, for all the amazement that such a museum can provide, it is also a saddening reminder that what once was the forefront of human ambition and endeavor has now been largely resigned to history. NASA budgets are cut annually [2] whilst military expenditure takes ever more precedence. A planned six percent budget decrease in 2013 is the equivalent savings to three hours of the Iraq and Afghanistan Wars. Instead of reaching to explore outer-space we are encouraged to get excited about the equivalent billions [3] invested on science exploring the subatomic inner-space world. Meanwhile, we tend to forget that the ambitions of space exploration are not just to satisfy some wide-eyed childhood yearning to explore, but the serious and sobering prospect of needing to ensure that we as a species can eventually colonize to other worlds and ensure we are not counting down the days to our extinction on an ever-more-precarious planetary solitude.

In the face of such indifference, such concepts of lifeboats have become marginalized to what is perceived to be a realm solely for loons and dreamers, or ‘space cadets’ as we used to call them back in the days of school. The trillion dollar question really is what it takes to redirect all that military investment into science & exploration instead. It is down to credibility. Governments shy away from investing public funds when there is a lack of credibility.

Our Youth, Thinking Outside the Box

Posted by in categories: business, defense, economics, education, engineering, human trajectories, military, philosophy, space, sustainability

Recently I attended the AIAA Rocky Mountain Region’s First Annual Technical Symposium, October 26, 2012. Link to Symposium Photos, here. Link to Symposium Presentations, here.

I must congratulate many of the presenters, our youth, our next generation leaders, for thinking outside the box. And I congratulate their supervisors, advisors and team members for facilitating a supportive environment that nurtures outside the box thinking.

Here is why. Several remarkable papers were presented. For example, Tom Joslyn (Lt. Col, PhD) presented “Use of Liquid Droplet Stream Momentum Transfer for Lunar and Interplanetary Missions”. By using liquid droplets to conserve and transfer momentum between the momentum storage spacecraft and the lunar landing spacecraft, one could reduce the LEO mass from 200,000 kg to 24,500 kg. The presentation wasn’t about theory. It was about the how such a concept would be Engineering Feasible. The type of liquids required, and the ejection and capture systems required. That is impressive.

Second, “Cockpit of the Future” by the Capstone Team. They presented many new concepts like Palm Piloteer, haptic feedback suits, wrap around displays and seat designs.

The Kline Directive: Technological Feasibility (2c) … continued

Posted by in categories: education, engineering, general relativity, nanotechnology, nuclear energy, particle physics, philosophy, physics, policy, scientific freedom, space

I was about to discuss the third of three concepts, but thought a look back would be appropriate at this time. In my earlier post I had shown that the photon/particle wave function could not be part of the photon/particle as this would violate the empirical Lorentz-Fitzgerald transformations and therefore, Einstein’s Special Theory of Relativity. The wave function is only the photon/particle’s disturbance of the spacetime it is in, and therefore explains why photons/particles have wave properties. They don’t. They disturb spacetime like a pebble dropped into a pond. The pond’s ripples are not the pebble.

In the recent findings, Dr. Alberto Peruzzo, University of Bristol (UK) the lead author of the paper and quoting “The measurement apparatus detected strong nonlocality, which certified that the photon behaved simultaneously as a wave and a particle in our experiment, … This represents a strong refutation of models in which the photon is either a wave or a particle.” This is a very important finding and another step in the progress of science towards a better understanding of our Universe.

Those of you who have been following my blog posts will recognize that this is empirical validation using single structure test that shows that both wave and particle properties occur together. What is required next, to be empirically rigorous, is to either confirm or deny that this wave function is a spacetime disturbance. For that we require a dual structure test.

If this wave function is a spacetime disturbance, then Einstein’s Special Theory of Relativity is upheld, and we would require a major rethink of quantum physics or the physics of elementary particles. If this wave function is a not spacetime disturbance but part of the particle structure, then there is an empirical exception to the Lorentz-Fitzgerald transformation and we would require a rethink of Einstein’s Special Theory of Relativity.

The Kline Directive: Technological Feasibility (2c)

Posted by in categories: defense, education, engineering, general relativity, nanotechnology, particle physics, philosophy, physics, 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 second of three concepts, that if implemented should speed up the rate of innovation and discovery so that we can achieve interstellar travel within a time frame of decades, not centuries. Okay, I must remind you that this will probably upset some physicists.

One of the findings of my 12-year study was that gravitational acceleration was independent of the internal structure of a particle, therefore, the elegantly simple formula, g=τc2, for gravitational acceleration. This raised the question, what is the internal structure of a particle? For ‘normal’ matter, the Standard Model suggests that protons and neutrons consist of quarks, or other mass based particles. Electrons and photons are thought to be elementary.

I had a thought, a test for mass as the gravitational source. If ionized matter showed the same gravitational acceleration effects as non-ionized matter, then one could conclude that mass is the source of gravitational acceleration, not quark interaction; because the different ionizations would have different electron mass but the same quark interaction. This would be a difficult test to do correctly because the electric field effects are much greater than gravitational effects.

The Kline Directive: Technological Feasibility (2b)

In this post I discuss three concepts, that if implemented should speed up the rate of innovation and discovery so that we can achieve interstellar travel within a time frame of decades, not centuries.

Okay, what I’m going to say will upset some physicists, but I need to say it because we need to resolve some issues in physics to distinguish between mathematical construction and conjecture. Once we are on the road to mathematical construction, there is hope that this will eventually lead to technological feasibility. This post is taken from my published paper “Gravitational Acceleration Without Mass And Noninertia Fields” in the peer reviewed AIP journal, Physics Essays, and from my book An Introduction to Gravity Modification.

The Universe is much more consistent than most of us (even physicists) suspect. Therefore, we can use this consistency to weed out mathematical conjecture from our collection of physical hypotheses. There are two set of transformations that are observable. The first, in a gravitational field at a point where acceleration is a compared to a location at 0 an infinite distance from the gravitational source, there exists Non-Linear transformations Γ(a) which states that time dilation ta/t0, length contraction x0/xa, and mass increase ma/m0, behave in a consistent manner such that:

The Kline Directive: Technological Feasibility (2a)

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 set of posts I discuss three concepts. If implemented these concepts have the potential to bring about major changes in our understanding of the physical Universe. But first a detour.

In my earlier post I had suggested that both John Archibald Wheeler and Richard Feynman, giants of the physics community, could have asked different questions (what could we do differently?) regarding certain solutions to Maxwell’s equations, instead of asking if retrocausality could be a solution.

I worked 10 years for Texas Instruments in the 1980s & 1990s. Corporate in Dallas, had given us the daunting task of raising our Assembly/Test yields from 83% to 95%, within 3 years, across 6,000 SKUs (products), with only about 20+ (maybe less) engineers, and no assistance from Dallas. Assembly/Test skills had moved offshore, therefore, Dallas was not in a position to provide advice. I look back now and wonder how Dallas came up with the 95% number.

The Kline Directive: Technological Feasibility (1)

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

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 5a)

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

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.

I was not intending to write Part 5, but judging from the responses I thought it was necessary to explain how to read a journal paper – and a good read cannot be done without a pen and paper. If you are writing a paper, when you have completed it, I would suggest you set it aside for at least a week. Don’t think about your paper or the topic during this shmita period. Then come back to your paper with a pen & paper and read it afresh. You’d be surprised by the number of changes you make, which means you have to start well before your deadline.

Note, you can find articles on how to review or write papers and here is one, by IOP (Institute of Physics, UK) titled Introduction to refereeing, and is a good guide to read before reading or writing a paper. This is especially true for physics but applies to all the sciences and engineering disciplines.

Note, for those who have been following the comments on my blog posts, IOP explicitly states “Do not just say ‘This result is wrong’ but say why it is wrong…” and “be professional and polite in your report”. So I hope, we as commentators, will be more professional in both our comments and the focus of our comments. Thanks.
