Okay, so the title of this newsletter issue is another reference to a movie I like - but this reference is much more direct. “Japanese Story” is an Australian movie from 2003, starring Toni Collette, that tugged on my heartstrings when I watched it maybe 20 years ago.

There we go. There's that word we hear so often as skeptics, 'quantum'. It seems likely Ky is referring to a state called 'quantum entanglement' that results in entangled particles (and photons) having their states correlated over theoretically limitless distances, through tiny wormholes.

On 27 January POTUS (the President Of The United States) signed an executive order to create an “Iron Dome” of defence against ballistic, hypersonic, cruise missiles and other advanced aerial attacks. This was renamed “Golden Dome for America” on 24 February. Surprisingly, the renaming isn't about POTUS' preference for golden things. Apparently “Iron Dome” is a registered trademark, owned by an Israeli defence firm.

I just got back last week from my third experience riding in the Cavalcade. This year it was held in Twizel and, the same as last year, we rode with the heavy wagons. To clarify, we rode our horses alongside and around a bunch of wagons, carts, and buggies of all shapes and sizes. Part of the deal when you get to ride with the wagons is you should be ready to jump off and assist at times. For example, when a buggy with no brakes had to ascend a steep slope, another person and I had to jump off and be the brakes by hanging onto a rope tied to the back of the buggy. I can feel the anxiety just recalling the memory.

This week I will comment on two articles. The first is an article from Science Advances by Richardson et al. 9 from 13 September 2023. This is a research article with the title “Earth beyond six of nine planetary boundaries”. This article is a collaboration between multiple climate scientists, including those from the renowned Potsdam Institute (Rockstrom et al).

The Christmas before last, I received a work email informing me of the holiday dates during which our office would be closed, and that for these dates I would need to book annual leave. I guess in an attempt to soften the blow of people needing to use over half of their annual leave on days outside of their choosing, management decided to let us know of the benefits of taking leave:

The IPCC report of 2022 notes that climate change is a major risk to planet Earth. (IPCC 2022). New Zealand's Net Zero Carbon Act has been passed by parliament, and has been accepted by the National party, Labour Party, Green party, ACT party and Te Pati Maori. The NZ First Party is ambivalent. This would suggest that very urgent and far-ranging changes are necessary to our society in New Zealand within the next six years, to try to get to 1.5° C of global warming by 2050 - or preferably earlier. It should be noted that we are already close to that target in 2024, and atmospheric greenhouse gases have increased rather than decreased year by year since then. These have led to year-on-year increases in record temperatures, with associated increases in floods, droughts, wildfires, strength of storms, sea level rise and catastrophic effects in many countries including New Zealand. The most affected countries are in the “Global South”, yet they produce the least greenhouse gases. New Zealand is the 7th highest producer of greenhouse gases per person in the world.

Kahneman's book Thinking Fast and Slow (2013) is a good starting point for thinking about the strengths and limitations of human thinking processes. There is no good substitute for the use of “educating gossip”, as Kahneman describes it, for training in effective judgement and in decision making.

Forgive me this short item, as it's been a pretty busy weekend. I had good intentions, but today my wife and I decided that we needed some more shelving space in our garage. I'd mentioned putting in another shelf below one that I had already installed some time ago, but she managed to convince me that it would be better to extend the Elfa wire rack system that we already have in our garage. What was intended to be a half hour job turned into a couple of visits to Mitre 10, and several hours of moving stuff around and installing everything. Still, we're very pleased with the result and we now have considerably more space to store various garage essentials.

I trust you all voted in our recent fractious election, even if your vote was “None of the above”, as democracy is more precious than some people realise. Democracy is under fire in many parts of the world, as people become sceptical about its benefits, or as some awful leaders and their parties come to power, or (as is the case in the US) threaten to. But there is another way of looking at the purpose of democracy, as proposed by the eminent philosopher Karl Popper.

Abi Loeb, who went against the tide of the scientific community back when the asteroid Oumuamua passed earth, and claimed it was an alien artefact, has struck again. This time, YouTube alerted me (presumably because I've been watching the UAP nonsense unfold on credulous American news channel News Nation) to the existence of a News Nation interview with Avi about his recent discovery of small spherules of alien origin dredged up from the seabed.

I'm sure everyone is aware of the protests that happened last week. I watched them from the comfort of my home, and didn't feel the need to visit the march on Parliament on Tuesday or experience the “gridlock” in Wellington central on Saturday. There was one thing at Tuesday's protests that really struck me. The protesters, under the banner of the Freedoms and Rights Coalition (created by “Apostle” Brian Tamaki), have been asking for our best protections against people dying of COVID to be removed - lockdowns, vaccine mandates, MIQ, and all other restrictions. A frequent message throughout the day was about the government needing to listen to the public - the speakers outside parliament talked about how a government should heed the people.

Bob Metcalfe (Skeptic No 75) might have been reading New Zealand Tone magazine: Bringing Technology to Life, Sept-Oct 2004. The front cover promises "Hi-fi cables: science or hocus pocus", and on page 46 there is an interview with Bob Noble, "sales manager for respected cable manufacturer Chord". On page 47 there is a review of three Chord cables. The only science in the interview is the importance of screening to cables since cheap electronics in homes today are "leaking interference back into the same mains power ring that supplies the hi-fi. This degrades the final sound considerably. If you don't believe me, turn all those other appliances off and see what it does to your hi-fi sound." Nobody puts the case that there is any hocus pocus to cables.

THE committee notes with sadness the sudden death of George Errington. George and his wife Helen joined NZCSICOP in 1986 and have been active, enthusiastic members. He was a "behind the scenes" worker who shunned the limelight. For that reason, his loss is perhaps particularly keenly felt by the Secretary; he gave his time and creative and engineering skills generously to the increasingly onerous task of preparing this newsletter for distribution. His last contribution to the New Zealand Skeptics was to assist in devising a new system for managing our growing membership and subscription list. He will be greatly missed.

Home water treatment systems are often promoted on the basis of the purported health (rather than aesthetic) benefits of using them. This is particularly in relation to urban drinking water given the full treatment -- coagulation, sedimentation, filtration and disinfection -- where such claims usually constitute misleading advertising. In this review I will focus on a number of misconceptions about the health benefits of water treatment, examining each assertion in its wider context. The ensuing discussion applies less to rural water supplies, where valid reasons often exist for use of treatments -- eg removing nitrate or protecting against giardia.

At the Skeptics' conference we were treated to one official's view of the status of scientific medicine relative to alternative treatment systems and beliefs. This presentation reinforced many of our fears that modern medicine is truly the victim of its own success. Now that so many of us live to old age, and find that pharmaceuticals and surgery can do little to prevent inevitable decline, we are encouraged to turn to away from "Western orthodoxy" towards "alternative" systems of other, more "spiritual and "holistic cultures".

Dr Michael Evans, a former student of Atlantic College, came last week to give a Friday evening lecture on anthroposophical medicine (A.M.). From what J can gather, it seems to be a system of medicine founded at the instigation of Rudolph Steiner, who claimed that a science limited to what was perceptible by the physical senses and using only analytical thinking would not be capable of understanding the fundamental life processes of man. A.M. believes that many illnesses are not wholly or ultimately explicable in terms of disordered physics and chemistry, but that the subject of the illness is lacking in some "vital essence" or that the vital essence has been disturbed in some way. It questions the reductionist approach of breaking down processes to the cellular or molecular level because: :
