trukterious··on How to build a Moon base
Apparently there's stuff like gold, iridium, silver, osmium, palladium, platinum, rhenium, rhodium, ruthenium and tungsten.

These might be transported back to earth. Plus there's iron, cobalt, manganese, molybdenum, nickel, aluminium, and titanium for construction of moon settlements and factories.

trukterious··on How to build a Moon base
Yes but not all in the same place, so the ore would presumably be less concentrated?
trukterious··on How to build a Moon base
Hmm, interesting. I was thinking that we could mine fresh debris from the asteroids themselves, in concentrated form. Plus saving the earth, of course.
trukterious··on How to build a Moon base
Plan B. Crash dozens of asteroids onto the moon at a few designated locations. (Use rocks that might hit the earth or pass fairly close). Offer free mining rights to companies on a first-there-first-served basis.
trukterious··on Green tea supplements ruined my liver
>how could we have possibly made it as long as we have as a species if we are only now realizing that we can't eat enough good foods to be healthy?

Partly due to agricultural soil depletion of certain elements like magnesium, zinc, iodine.

Btw our prehistoric ancestors weren't especially healthy either:

trukterious··on Green tea supplements ruined my liver
I do eat quite a lot of broccoli but I still don't fancy eating 7 heads every day -- enough to cover two dinner plates.

So I take a magnesium tablet before bed. Less work to prepare and to digest.

The present moral aversion to supplements seems faddish to me. We've gone from one extreme in the 1960s where everyone looked forward to taking all food in pill form, like fictional astronauts, to another extreme where supplements of any kind are frowned upon by many including in the medical establishment. Some supplements don't absorb very well, it's true, and some consumers are irresponsible -- yet atoms are atoms and molecules are molecules regardless of the source.

trukterious··on Green tea supplements ruined my liver
>With normal healthy food you should get more than enough.

No, I looked into it some years ago and it seems unfeasible. For instance you'd have to eat about 15 stalks/heads of broccoli daily to get the RDA of magnesium, and that amount is likely suboptimal.

trukterious··on Space Transportation System
Say we were to crash potentially earth-destroying asteroids into the moon and then offer free mining rights to companies on a first-to-get-there basis.

I think we would still hear a a cacophony of moral objections. A spirit of pessimism seems to be hanging over us these days:

trukterious··on Americans lose confidence they can sniff out social media bots
Not really -- for instance, at HN we pay more attention to comments that explain stuff well, refer to sources, and so on.

The bots might be a blessing, in some ways, if they result in more people looking for good explanations rather than for assertions or herd direction; assessing ideas rather than their sources.

trukterious··on Consumption of ‘Longevity’ Vitamins Could Prolong Healthy Aging, Scientist Says
Fasting is very relevant here because it puts the body deeper into repair and maintenance mode. My guess is is periodic fasting plus a modest regimen of longterm repair supplements would be the optimum strategy.
trukterious··on Spreadsheet of Steven Pinker’s book recommendations
I read Dawkins before Darwin, which made sense. Just as, if I wanted to learn relativity, I wouldn't go to Einstein's papers first.
trukterious··on Mathematics as thought
How about in the process of reading a proof? Each single step is validated by the intuition of the reader.
trukterious··on The last lighthouse keeper of Capri
Indeed. Great view, time for reading and thinking, steps for exercise, saving lives, few social events to attend...
trukterious··on What we lose by reading 100,000 words every day
It's more like 'thinkjuice'. The act of making all the perceptual discriminations required to consume 100,000 words cuts into the cognitive budget.
trukterious··on A New Biography of Churchill
The difference is that the things that we praise Churchill for, e.g. leading the unpopular fight against the Nazis, were almost unique to him. Yet the charge that 'he favored eugenics and was deeply racist' could be levelled at many or most of his peers.
trukterious··on A New Biography of Churchill
Absolutely. The greater the man, the greater the flaws. Yet we still need heroes from history to look up to, and we can't judge solely by modern standards.

By analogy consider the contemporaneous movie The Wizard of Oz (1939). It's enjoyable and arguably morally-improving to watch. We are the better for it. Yet a great deal of immorality existed behind the scenes:

trukterious··on How to Get Things Done When You Don't Feel Like It
You can't do a thing you don't feel like doing. Ask David Hume, or ask any depressed person.

In reality our ideas about what we should be doing co-evolve with our feelings about doing those things.

trukterious··on Progress in Philosophy
>philosophical exports are the kinds of thing that, once you internalize them, just seem like the way things are

Yes; if you like a philosophical idea that's usually sufficient for you to have 'adopted' or 'accepted' it. Yet, in addition, philosophical problems have been solved. It's just that ipso facto they then become part of science or some other discipline, so we don't notice so easily. For example, the theory of evolution was an example of philosophical progress (a new way of thinking about something, in this case life). But it's now part of biology. Another example is that Karl Popper solved the problem of induction. It's controversial that he did so. But if it shelves off into some other field, e.g. AGI, then perhaps his achievement will be more widely accepted as such.

trukterious··on “Social network” of brains lets people transmit thoughts to each other’s heads
Or from the final episode of Firefly:

Jayne: Well, I don't like the idea of someone hearin' what I'm thinkin'.

Inara Serra: No one likes the idea of hearing what you're thinking.

trukterious··on Late Bloomers: Why Do We Equate Genius with Precocity? (2008)
Well I'm not talking about obsession in the sense of a mental disorder -- but in the sense of that one thing X that a particular person happens to be in love with at the moment (could be piano, could be tennis, could be computer programming or could be something socially disapproved of like pokemon or skateboarding or whatever). The obsession creates a depth of knowledge. Even when you try to make such people do other stuff, they'll still be daydreaming about X. So better to work with it.

>educational system [...] stop focusing on what you are best at and most passionate about to improve your "grades"

Yes. Precocious boys follow a sequence of obsessions. The way to foster achievement, then, is to find out what a child loves and help him to do more of it. Ultimately this may involve finding a master who can act as mentor. It's not going to happen in conformity factories dominated by ideologies (and often policed by bullies).

trukterious··on Hundreds of academics at top UK universities accused of bullying
>increase autonomy of all participants of the system

Yes, forced association causes bullying. There's no bureaucratic 'solution' that won't be gamed by the bullies. And there's no substitute for having good/brave people around the place.

trukterious··on Hundreds of academics at top UK universities accused of bullying
The twist is the 'crybully' -- someone who bullies others and claims victimhood when confronted. In this way an accusation or counter-accusation of bullying can itself be a form of bullying.
trukterious··on Linus Torvalds: 'I'll never be cuddly but I can be more polite'
People aren't like resources to be harvested: they are 'ends in themselves', i.e. with their own lives and perspectives. Also, unlike an extractable resource, their goodness is variegated.
trukterious··on Physics Makes Aging Inevitable, Not Biology (2016)
This article is written as if Aubrey de Grey didn't exist!

In addition to the featured scrapyard cars one could peruse these vintage models:

https://www.classiccarpassion.com/media/101072/55.jpg

They still go because comprehensive maintenance and damage repair has been carried out -- repeatedly. The same approach is viable for the human body, argues de Grey.

trukterious··on Linus Torvalds: 'I'll never be cuddly but I can be more polite'
I don't think that there are any garbage people. Everybody has some good in them. (This doesn't imply we shouldn't set some boundaries).
trukterious··on There's Not Enough Time
The author's problem is that there's a gap between what he's doing and what he thinks he ought to be doing. On the plus side he's already got some perspective via his humorous writing.

In addition he might try and do nothing for a spell: I've found this to be impossible. One can then relax and watch oneself doing the truly essential tasks. Automatically. This is the 'ability to let that which does not matter truly slide' (Tyler Durden in Fight Club).

trukterious··on Learning from Pain
Pain is a signal that something is wrong and needs attention. Yet we also choose pain because it can feel pleasurable.

e.g. eating chilli causes pain, which is interpreted as pleasure

e.g. leaving everything to the last minute, which is interpretted as a 'buzz'

Even in such situations the pain remains a sign that something is wrong, that the personality may be out of balance. Why hurt yourself or make things harder? Like the dictator who deliberately creates hardship in order to remain in power...

trukterious··on We still don’t understand motion sickness
Yes. Also the driver can anticipate the various accelerations more accurately than the passengers since he is causing them.

As a passenger I find I can read in reasonable comfort if I can look up and out of the vehicle at each acceleration i.e. at turns, when stopping/starting.

trukterious··on How to be alone: the difference between loneliness and solitude
It seems to me like gregarious people and loners can be after the same thing. Some people want acceptance and approval from others whereas other people have more of an inner connection to the same source.

What is the source? We don't understand (yet) but it's an interesting clue that the things other people like about you aren't necessarily the things you like about yourself.
