Gravity Modification – New Tools

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

To understand why gravity modification is not yet a reality, let’s analyze other fundamental discoveries/inventions that changed our civilization or at least the substantially changed the process of discovery. There are several that come to mind, the atomic bomb, heavier than air manned flight, the light bulb, personal computers, and protein folding. There are many other examples but these are sufficient to illustrate what it takes. Before we start, we have to understand four important and related concepts.

(1) Clusters or business clusters, first proposed by Harvard prof. Michael Porter, “a business cluster is a geographic concentration of interconnected businesses, suppliers, and associated institutions in a particular field. Clusters are considered to increase the productivity with which companies can compete, nationally and globally”. Toyota City which predates Porter’s proposal, comes to mind. China’s 12 new cities come to mind, and yes there are pro and cons.

The Fabulous Spaceport Colorado (Part 3)

Posted by in categories: business, defense, economics, education, engineering, geopolitics, policy, space

Last month a colleague of mine and I visited with Dennis Heap, Executive Director of the National Front Range Airport, at Watkins, CO, the location of the future Spaceport Colorado, and Colorado’s contribution to getting into space. Here is Part 3.

In my last post I had mentioned that there were 2 business models for spaceports. I’ll name the first Sweden-America model after spaceports Sweden & America. The second, I’ll name Colorado-Singapore model after (yet to be) spaceports Colorado & Singapore.

The Sweden-America model basic premise is that spaceport ought to be built in remote locations, and then a hinterland economy is eventually built around the spaceport. This approach was originally driven by safety concerns and the need for a rocket range or vacant land for launching rockets to crash back to.

The basic premise of the Colorado-Singapore model is that launch vehicles are safe and that spaceports ought to be built close to centers of commerce and intermodal transportation networks. That is, spaceports are to be built in an existing hinterland economy.

The Kline Directive: Technological Feasibility (3b)

Posted by in categories: cosmology, defense, economics, education, engineering, general relativity, particle physics, 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 a previous post on Technological Feasibility I had stated that a quick and dirty model shows that we could achieve velocity of light c by 2151 or the late 2150s. See table below.

Year Velocity (m/s) % of c
2200 8,419,759,324 2808.5%
2152 314,296,410 104.8%
2150 274,057,112 91.4%
2125 49,443,793 16.5%
2118 30,610,299 10.2%
2111 18,950,618 6.3%
2100 8,920,362 3.0%
2075 1,609,360 0.5%
2050 290,351 0.1%
2025 52,384 0.0%

That is, at the current rate of technological innovation we could as a civilization reach light speed in about 140 years. More importantly we could not even reach anywhere near that within the next 100 years. Our capability would be 6.3% of c.

The Lorentz-Fitzgerald transformation informs us light speed would require an infinite amount of energy (i.e. more than there is in the Universe!), thereby highlighting the weaknesses in these types of technological forecasting methods. But these models still serve a purpose. They provide some guidance as to what is possible and when. The operative word is guidance.

Solving Complex Problems

Posted by in categories: complex systems, education, homo sapiens

Solving complex problems is one of the defining features of our age. The ability to harness a wide range of skills and synthesise diverse areas of knowledge is essentially integral to a researcher’s DNA. It is interesting to read how MIT first offered a class in ‘Solving Complex Problems’ back in 2000. Over the course of a semester students attempt to ‘imagineer’ a solution to a highly complex problem. There is a great need for this type of learning in our educational systems. If we are to develop people who can tackle the Grand Challenges of this epoch then we need to create an environment in which our brains are allowed to be wired differently through exposure to diverse areas of knowledge and methods of understanding reality across disciplines.

When I look at my niece who is only 4 years old I wonder how I can give her the best education, and prepare her to meet the challenges of this world, as she grows up in a world which fills my heart with great anxiety. It is fascinating to read about different educational approaches from Steiner education to Montessori education to developing curriculums and school design upon cognitive neuroscience and educational theory. However when I look at the thinkers of insight, and contrast it with educational policy in the developed world, there is quite clearly a huge disconnect between politics and science.

We need to develop a culture of complexity if we are to develop the ability and insight to solve complex problems. When we look at the world from the perspective of complexity it builds a very different mindset in how we think about the world, and how we go about trying to understand the world, and ultimately how we go about solving problems.

The Kline Directive: Technological Feasibility (3a)

Posted by in categories: cosmology, defense, education, engineering, general relativity, particle physics, 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.

My apologies to my readers for this long break since my last post of Nov 19, 2012. I write the quarterly economic report for a Colorado bank’s Board of Directors. Based on my quarterly reports to the Board, I gave a talk Are We Good Stewards? on the US Economy to about 35 business executives at a TiE Rockies’ Business for Breakfast event. This talk was originally scheduled for Dec 14, but had moved forward to Nov 30 because the original speaker could not make the time commitment for that day. There was a lot to prepare, and I am very glad to say that it was very well received. For my readers who are interested here is the link to a pdf copy of my slides to Are We Good Stewards?

Now back to interstellar physics and the Kline Directive. Let’s recap.

In my last four posts (2c), (2d), (2e) & (2f) I had identified four major errors taught in contemporary physics. First, to be consistent (2c) with Lorentz-Fitzgerald and Special Theory of Relativity, elementary particles contract as their energy increases. This is antithetical to string theories and explains why string theories are becoming more and more complex without discovering new empirically verifiable fundamental laws of Nature.

The Kline Directive: Technological Feasibility (2d)

Posted by in categories: cosmology, defense, education, engineering, general relativity, 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, Legal Standing, Safety Awareness, Economic Viability, Theoretical-Empirical Relationships, and Technological Feasibility.

In this post on technological feasibility, I point to some more mistakes in physics, so that we are aware of the type of mistakes we are making. This I hope will facilitate the changes required of our understanding of the physics of the Universe and thereby speed up the discovery of new physics required for interstellar travel.

The scientific community recognizes two alternative models for force. Note I use the term recognizes because that is how science progresses. This is necessarily different from the concept how Nature operates or Nature’s method of operation. Nature has a method of operating that is consistent with all Nature’s phenomena, known and unknown.

If we are willing to admit, that we don’t know all of Nature’s phenomena — our knowledge is incomplete — then it is only logical that our recognition of Nature’s method of operation is always incomplete. Therefore, scientists propose theories on Nature’s methods, and as science progresses we revise our theories. This leads to the inference that our theories can never be the exact presentation of Nature’s methods, because our knowledge is incomplete. However, we can come close but we can never be sure ‘we got it’.

Is Failure to Prepare Our Silent Existential Event?

Posted by in categories: education, existential risks, lifeboat, sustainability

Note: The below is exclusively about the United States of America, yet the theme is international.

Each time an extreme weather event takes place humanity is reminded again that basic preparation for an off-grid experience did not take place across large swaths of an affected population. Ironically, it does not begin to take place, publicly and en masse, after the event.

Saving humanity will have a lot to do with teaching a kid to build a fire, in the near term. More esoteric “preservers” and “shields” have their place, but “Scout” knowledge can produce immediate quantitative and qualitative improvements in humanity’s survival capabilities, fast.

After weather-induced disasters, our tendency is toward construction of physical things – better towers, more resilient dams, improved architecture. Seldom do we do anything to improve ourselves. Thousands remain helpless and dependent in the face of the Hurricane “Sandy” aftermath.

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.
