I've missed about three months' worth of blog entries on my normal schedule, so here are as many short ones to bring me up to May...

Everybody is talking about the certainty of catastrophic climate change - "if we don't do something" - so I'd like to point out how certain a scientific hypothesis is, is dependent on its method of proof. Something rarely if ever discussed in the media.

To make it simple I propose everyone use a pyramid schema for the strength of a scientific theory, similar to the one that used to be printed on cereal boxes for nutritional value, except upside down:

• The broad top of the pyramid is stuff that has been proven, & peer-reviewed okay by being able to repeat the procedure/experiment & ending up with the same results over 95% of the time. This is the "A grade" most hypotheses should aspire to (but some don't bother).
• The middle section is in two parts: The first group is all matured empirical science - i.e. data gets collected, but no real axiomatic theory is visible at first. Over time (many decades as a rule) some structure is discerned, piece by piece, and the empirical data plus a few straight-forward theses of how they came to be has some predictive power. The theory of evolution is part of this group. -- The second similar group here seems to me to be anything that "works like magic": Think of a clever mechanic fixing something in a troublesome engine, and not sure why it works. It can be repeated by any number of people, i.e. is highly predictive, but there is no good explanation for it. Some mathematical theorems are like that (e.g. Fermat's last theorem for the longest time, until recently).
• The tiny tip on which the pyramid is balancing consists of hypotheses that apply to complex systems, for which a straight-forward model (usually based on a few equations) does not suffice to explain all past data. This is the "theorem-with-little-or-no-proof" category. As a rule the theory predicts some behaviour of the target system correctly in time and space, but often way below the usual 95% mark. Diagnoses of psychological aberrations are examples of this kind of science.

So, if we call them "big top", "medium I" & "medium II", and "little foot", whch one of these would you say is the one for the current climate change theory?

We Germans don't allow ourselves to feel pride for our country most of the time, most of us. One of the many consequences of the murder spree of a certain nationalist government eight decades ago (and the mayhem they generally caused in the decade that followed).

I don't fit that mold too well because I grew up in Africa, where I often had to defend my being German in an English-speaking environment. So I tend to automatically look for things I can be a little German-proud of.

And one thing I've noticed in recent years, that I missed in the closing years of the 20th century: There are a lot more foreign-looking women passing by on the streets of major German cities, away from tracks beaten by tourists, and about a third of them are smiling. Naturally, I particular take note of African women.

They may be doing something with their mobile phone, may be playing with their children on the U-Bahn, or just talking to someone in the supermarket.

And the very fact that they are there means Germany is in a phase where female foreigners tend to come here more often than in the more dire times when you had to fight hard to be able to remain in Germany if you'd arrived a short time ago. Which meant mainly men would try...

Germany is slowly opening up. Instead of always saying loudly for all to hear that we are not an immigration country ("Einwanderungsland") there now is actually a rumour that we may have our first ever immigration law Real Soon Now. (Wow!)

Whenever someone - usually of younger age - is showing me some new app that makes something that used to be done in a more roundabout, perhaps entirely analogue, way till now, "so much easier", I wonder if they - and many, many others almost everywhere - don't see that apparent ease-of-access often has a highly deleterious effect on life diversity.

Two examples: My favourite video store has thousands of DVDs of feature & documentary films and series. Three people service my requests behind the counter, and all of them know their stock pretty well, and, in addition, have gotten to know my tastes pretty well over the years, too. The rapport is such that, if I say I don't know what I want to take with me at a given visit, within seconds, I will have something in hand they recommend, that I never saw before. -- This great, personalised and huge-spectrum service is in jeopardy of going out of business soon, due to developments like Netflix and direct DVD rental via the WWW. The latter are as a rule much less personalised, and way less diverse (i.e. the selection of films/series offered is 2 or 3 orders of magnitude smaller); and, in any case, I don't get to move my bod (exercise muscles) and talk with real people (exercise brain, social skills department) most of the time.

Second case: A neat small travel agency, run by a usually bright-spirited woman a few years older than me, used to sell me train and plane tickets a few years ago, as well as the one or other package holiday. Then the German Rail upped the "license fee" such agencies had to pay if rail trips were ticketed by them, rather than the big customer care units in train stations, or the company web site. This meant the nice lady's main branch of business - selling train tickets to older folk - basically collapsed, and she went out of business soon after that. Why do I miss her? Because whenever something went wrong on the many trips I went on, all over the world, I knew I could always call her as a last resort and be sure she would have my back, even from far away Germany, eventually getting me home. No digital system or German Rail "customer care" will develop that level of loyalty. Ever.

So, my advice to those seekers for hand-held "ease" is: Pay attention to who has the power & the social back-bone to supply you with whatever gives your life diversity, and do all you can to protect those people and allow them to continue doing the good work they're doing - for lots of people. As a rule without any major material profits on their side.

Because you can be sure that some piece of software will not be able to develop that kind of diversity & loyalty to you, for a long time to come. And even if it could, what would be the profit for the producer of that software? She/He will always "optimise" their product to maximise the cash flow from you to them. So the software will be loyal to them first, second and third. (And in terms of loss of diversity, refer to "Netflix" in the first case's paragraph, above...)

Some apps can be "sinks", i.e. they suck up diversity and true care of you, the user, while you're being dazzled by the user interface. Beware such sinks, and use trajectories that get you out if you're already sunken in, or help you steer clear altogether.

Somewhere else in the Web I'm "launching" a new list-keeping log of 10 little "life motivators" of what happened in the preceding 4-5 weeks; i.e. stuff that went well or was well-received. On a monthly basis.

Just to remind my black-heartedly pessimistic brain...

Here - once-off - is the initial offering:

1. having begun reading Hesse's best advice for quinquagenarians in novel form again
2. the best little video shop in Berlin now stocking THE GOOD WIFE, sn. 6
3. more frequent contact with a pleasant Canadian native who turns out to be a bookworm like me
4. discovery of DeConnick's run at "Marvel Now" detailing the new & crazy funny exploits of CAPT. MARVEL, now mantled by potent blonde Carol Danvers!
5. rediscovery of the Thunderous countdown restarting again, at last!
6. getting my step counter to run again (somewhat) even if I do still keep walking - now to get back to 8000 on average
7. continuing with MARCO POLO - both the Netflix series and the Bergreen travel journal paperback
8. finding a few last chestnuts underfoot, to keep on various desks
9. wonderfully warm start of autumn in Berlin
10. Merkel sticking to her refugee civility guns for now

That wasn't as hard as I thought. Flow, my ups, the policeman said.

I need to lose some weight. In essence, I need to eat less & drink more water.

So I decided to reboot an old idea: Fast for 1 day a week from now on, a kind of personal Ramadan every Wednesday or Thursday of any week.

So as not to overdo it, allow myself to drink as much water as desired. Eat only fruits or vegetables all day. All this until sundown, which at the moment is quite late.

Well, I more or less did it on the 1st iteration now. I'll get better next week, and the week after, etc.. Hold a thumb for me.

And, since this is a little about frugality & suffering, a path not only I am embarking on, I'm going into an ever so small solidarity mode with those others. Calling this something to "overwrite" the word that has now suddenly become taboo: We'll have no more "Grexits"... here comes
