Story telling

As a kid (four or five, I can’t remember clearly enough, although I can remember exactly where I was standing and what I was thinking about) I can clearly recall wondering whether it was necessary to hold onto the reasoning behind a conclusion, or whether is was only the conclusion that matters.

I foolishly decided only the conclusion matters, whereas (as there is no truth, only debate and argument) only the reasoning is really significant.

I think, in a nutshell, that I will tell my kids that “you must always be able to tell a story”.  Telling a story is the best way to remember something, and the best way to make the reasoning/context accessible to other people.

I will begin doing this myself.

It’s OFFICIAL!!! You don’t need DRUGS to be HAPPY!!!

  • Think positive
  • Get plenty of sunlight outdoors
  • Do exercise
  • Eat well

This is how you can excrete more serotonin without drugs, thereby becoming a happier and more successful human being.

The Perils of Nuclear Power

An interesting post from the Guardian.co.uk :

http://www.guardian.co.uk/environment/2011/apr/11/nuclear-apologists-radiation

Soon after the Fukushima accident last month, I stated publicly that anuclear event of this size and catastrophic potential could present a medical problem of very large dimensions. Events have proven this observation to be true despite the nuclear industry’s campaign about the “minimal” health effects of so-called low-level radiation. That billions of its dollars are at stake if the Fukushima event causes the “nuclear renaissance” to slow down appears to be evident from the industry’s attacks on its critics, even in the face of an unresolved and escalating disaster at the reactor complex at Fukushima.

Proponents of nuclear power – including George Monbiot, who has had a mysterious road-to-Damascus conversion to its supposedly benign effects – accuse me and others who call attention to the potential serious medical consequences of the accident of “cherry-picking” data and overstating the health effects of radiation from the radioactive fuel in the destroyed reactors and their cooling pools. Yet by reassuring the public that things aren’t too bad, Monbiot and others at best misinform, and at worst misrepresent or distort, the scientific evidence of the harmful effects of radiation exposure – and they play a predictable shoot-the-messenger game in the process.

To wit:

1) Mr Monbiot, who is a journalist not a scientist, appears unaware of the difference between external and internal radiation

Let me educate him.

The former is what populations were exposed to when the atomic bombs were detonated over Hiroshima and Nagasaki in 1945; their profound and on-going medical effects are well documented. [1]

Internal radiation, on the other hand, emanates from radioactive elements which enter the body by inhalation, ingestion, or skin absorption. Hazardous radionuclides such as iodine-131, caesium 137, and other isotopes currently being released in the sea and air around Fukushima bio-concentrate at each step of various food chains (for example into algae, crustaceans, small fish, bigger fish, then humans; or soil, grass, cow’s meat and milk, then humans). [2] After they enter the body, these elements – called internal emitters – migrate to specific organs such as the thyroid, liver, bone, and brain, where they continuously irradiate small volumes of cells with high doses of alpha, beta and/or gamma radiation, and over many years, can induce uncontrolled cell replication – that is, cancer. Further, many of the nuclides remain radioactive in the environment for generations, and ultimately will cause increased incidences of cancer and genetic diseases over time.

The grave effects of internal emitters are of the most profound concern at Fukushima. It is inaccurate and misleading to use the term “acceptable levels of external radiation” in assessing internal radiation exposures. To do so, as Monbiot has done, is to propagate inaccuracies and to mislead the public worldwide (not to mention other journalists) who are seeking the truth about radiation’s hazards.

2) Nuclear industry proponents often assert that low doses of radiation (eg below 100mSV) produce no ill effects and are therefore safe. But , as the US National Academy of Sciences BEIR VII report has concluded, no dose of radiation is safe, however small, including background radiation; exposure is cumulative and adds to an individual’s risk of developing cancer.

3) Now let’s turn to Chernobyl. Various seemingly reputable groups have issued differing reports on the morbidity and mortalities resulting from the 1986 radiation catastrophe. The World Health Organisation (WHO) in 2005 issued a report attributing only 43 human deaths directly to the Chernobyl disaster and estimating an additional 4,000 fatal cancers. In contrast, the 2009 report, “Chernobyl: Consequences of the Catastrophe for People and the Environment”, published by the New York Academy of Sciences, comes to a very different conclusion. The three scientist authors – Alexey V Yablokov, Vassily B. Nesterenko, and Alexey V Nesterenko – provide in its pages a translated synthesis and compilation of hundreds of scientific articles on the effects of the Chernobyl disaster that have appeared in Slavic language publications over the past 20 years. They estimate the number of deaths attributable to the Chernobyl meltdown at about 980,000.

Monbiot dismisses the report as worthless, but to do so – to ignore and denigrate an entire body of literature, collectively hundreds of studies that provide evidence of large and significant impacts on human health and the environment – is arrogant and irresponsible. Scientists can and should argue over such things, for example, as confidence intervals around individual estimates (which signal the reliability of estimates), but to consign out of hand the entire report into a metaphorical dustbin is shameful.

Further, as Prof Dimitro Godzinsky, of the Ukranian National Academy of Sciences, states in his introduction to the report: “Against this background of such persuasive data some defenders of atomic energylook specious as they deny the obvious negative effects of radiation upon populations. In fact, their reactions include almost complete refusal to fund medical and biological studies, even liquidating government bodies that were in charge of the ‘affairs of Chernobyl’. Under pressure from the nuclear lobby, officials have also diverted scientific personnel away from studying the problems caused by Chernobyl.”

4) Monbiot expresses surprise that a UN-affiliated body such as WHOmight be under the influence of the nuclear power industry, causing its reporting on nuclear power matters to be biased. And yet that is precisely the case.

In the early days of nuclear power, WHO issued forthright statements on radiation risks such as its 1956 warning: “Genetic heritage is the most precious property for human beings. It determines the lives of our progeny, health and harmonious development of future generations. As experts, we affirm that the health of future generations is threatened by increasing development of the atomic industry and sources of radiation … We also believe that new mutations that occur in humans are harmful to them and their offspring.”

After 1959, WHO made no more statements on health and radioactivity. What happened? On 28 May 1959, at the 12th World Health Assembly, WHO drew up an agreement with the International Atomic Energy Agency (IAEA); clause 12.40 of this agreement says: “Whenever either organisation [the WHO or the IAEA] proposes to initiate a programme or activity on a subject in which the other organisation has or may have a substantial interest, the first party shall consult the other with a view to adjusting the matter by mutual agreement.” In other words, the WHO grants the right of prior approval over any research it might undertake or report on to the IAEA – a group that many people, including journalists, think is a neutral watchdog, but which is, in fact, an advocate for the nuclear power industry. The IAEA’s founding papers state: “The agency shall seek to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity through the world.”

Monbiot appears ignorant about the WHO’s subjugation to the IAEA, yet this is widely known within the scientific radiation community. But it is clearly not the only matter on which he is ignorant after his apparent three-day perusal of the vast body of scientific information on radiation and radioactivity. As we have seen, he and other nuclear industry apologists sow confusion about radiation risks, and, in my view, in much the same way that the tobacco industry did in previous decades about the risks of smoking. Despite their claims, it is they, not the “anti-nuclear movement” who are “misleading the world about the impacts of radiation on human health.”

Religious progress

It’s not enough to argue that religion is just primitive superstition.  As (I believe) it reflects an underlying biological capacity to detect “too much” of everything – which then allows “too much” of anything to be recognised conciously (e.g. nature’s gods in the earliest phases) reasoned about (why are they there, what do they want, although we don’t understand it what is its impact)- generating abstract thought, religion has performed its myriad functions in binding that into the social system.

All of these “Too much” gods are inevitably extracted into concepts of a single god (even if the Roman part of Roman Catholicism resists getting rid of its minor gods completely).  Science, however, has become the process of separating the arbitrary transmission of past predjudices/ideas about “too much” whose purpose is more to do with psychological self-support in the face of a vast universe, and social bonding allowing for easier moral control,  into a systematic study of the abstract study itself where you are allowed to be wrong.

Thoughts on a new society

There is no utopia, but there is change, a trade off of advantages for disadvantages.
Typically in evolutionary systems, when an environment stays relatively constant competition within repeated generations creates a high degree of specialisation within the constraints of the environment.

We have engineered an environment within which we are very good at consumption, hoarding, travelling, and working at the expense of social and spiritual fulfilment. This environment came about out of historical circumstance, including benevolent motivations aligned with military and expansionist objectives.

Now we must modify our environment again, and become good at living in it. For this we should look at social out-riders for examples of how they structure their lives, and consider earlier philosophical branches of thought for the values we might try to cherish which would align with and reinforce the new environment socially.

Afterall, evolution is valueless and directionless outside survival within an environment. Many ways of living will lea to survival- but values and thought help us pick the most enjoyable.

Each change will bring new problems in alleviating the old, but it is progress if it keeps good parts of the old.

The politicians may not have absolute power -neither over the people nor the powerful, nor the government -, but now it is their job to negotiate and facilitate that change.

As it is, the current angloamerican empire has built itself as all empires do. Promised the rulers riches, backed those regimes that support it, undermined (economically, politically, militarily as necessary) and/or invaded those that do not.

What is to say the process now will be different? But, how can a movement based on low energy compete with one based on high energy and thus a more potent military? Partly through consensus, and only if it can reach people. It must change values by art and dialogue (as is partially happening), but pragmatically, it probably must recognise that it will not fundamentally alter the fact that, as seemingly in all evolutionary systems (particularly in our exponentially interlinked social reality), linear increments of success receive exponentially increasing reward – in all dimensions.

In this sense, it must also find ways to convince the corrupted, and the powerful, that any change can be conducted both in a way which preserves their interests but also will continue to profit them.

As in Kuhn’s analysis of shifts in scientific paradigms, a paradigm shift functions when the new paradigm is drawn up alongside the old long enough for the influential to jump across to the new intellectual vehicle. Perhaps this is what is happening right now in global politics, but perhaps not.

Gravity Driven Tai Chi

The idea of “gravity” is only a few centuries old, and still not fully understood… although it forms the principle force which exerts an influence on our physical body.  As a fighting art, Tai Chi would of course have had to account for this force, and it does so albeit using different more esoteric words and concepts.

During Qi Kung (not Qi Gong) today, while discussing the idea of feeling energy flowing into the ground (which seems like lying to myself) and energy flowing up into the universe, with a split being made at belly height, everything suddenly made sense with respect to gravity.

At any moment in time, ala school physics, there is not just a force acting downwards (gravity) there is also a force acting upwards (the resistance of the ground through which gravity is trying to pull you).  Internally, these two forces are acting simultaniously, as gravity tries to pull you down and through the earth, and your musculature, and skeleton, and will, try to keep you upright.

When, in Tai Chi they refer to energy flowing into the ground, I realised it seems possible to perceive this precisely at the moment where you relinquish as much resistance to gravity as possible, allowing the “down” force to exert its maximum influence (which results in as much down force as is basically possible without hooking yourself to something on the ground and pulling!).  Equally, energy flowing up into the heaven, can be perceived as precisely the motion of you acting against gravity to raise yourself.  These two concepts only work during motion – a change in position, releasing yourself to gravity, or acting against it.

The reasoning for the belly high split seems likely to be that Tai Chi attempts to establish a very solid foundation from which to launch strikes with the upper body (as opposed, for example, to Capoiera).  This means that it is desirable to maintain a downward force below the belly (i.e. from the top of the hips, while you release your body weight through the minimal possible structure preventing and hindering you from falling over whilst retaining flexibility to move) whilst above the belly one maintains an almost free-floating body able to strike, pull down, push up etc. i.e. using the spine and the roundness of the back primarily, to act with or against gravity.

To me, this seems to be a much simpler description of what is going on, using words which have modern meaning.

Parasite / Symbiote hypothesis

A while ago (over ten years now!!!) I remember reading a maths paper pointing out that parasitic and symbiotic relationships are held in relation, as should the pendulum swing too far in one direction, it becomes advantageous to follow the opposite strategy.

Here is an interesting pop sci article about some genetic evolution of simple robots. The end result wasn’t quite as equal as the maths paper suggested it might be, but is perhaps more recognisable in human society. I could easily imagine that it reflects a law :

“In this particular experiment, the stable evolutionary endpoint (after 500 generations) was that 60% of the robots were deceivers and 10% told the truth. Furthermore, about a third of the robots were slightly attracted to blue lights, another third were strongly attracted, and the final third avoided them completely.”

Although, sadly, those numbers look a bit loose.
