Question of the Week / Re: QotW - 25.02.07 - Are bone conduction headphones safer?

Completely off topic but it's great to see you back, Colin2B.

Thanks (did you really say that?). Hoping to stay for a while.

That sounds like it would make them all but useless.

Many are designed for running and keep position on the head quite well, although I have noticed some runners using a sweat band to add security.
I also use mine for listening to music when doing chores. The headband clips over the ears and goes around the back of the head, if I then sit in a high back chair the band gets pushed forward changing contact and volume. If I then push the band up to the crown of my head I find the position of the transducer gives a much louder sound than the standard position. Better contact?

A local marina has a problem with Starlings gathering in the rigging of yachts before going to their roosts in the nearby reed beds. Their droppings cause some nuisance to the owners particularly, when the birds have been feeding on blackberries. I watched one irritated owner come on deck with an air horn to scare them off. The sounds of 50+ birds lightening the load before taking off was reminiscent of a summer downpour!
I wonder if that could be similar with the chimps. If there is a cause for alarm, best to lighten up rather than stop behind a tree when the leopard is behind you. Urination could become associated with alarm, stress, get ready to run?

If the E-coli in faeces is harmful when introduced in the mouth, how did it get there in the first place?

Through the mouth. Like most harmful materials it?s a question of dosage and if you only ingest a small amount your body can cope, but it will still grow in the gut and be concentrated in the faeces to infect someone else.
There are lots of potentially harmful bacteria around that we cope with everyday. For example Honey contains the bacteria that causes botulism, but in such small amounts that we easily cope. However, honey shouldn?t be fed to children under 1 year as they can?t cope - similarly corn syrup.
Don?t know about feeding it to sheep however !

Do bone induction headphones without ear plugs pose the same risk to hearing loss as conventional headphones and ear buds?

Hi Bill
Although bone conduction headphones bypass the eardrum, they still activate the cochlea where most hearing damage is caused - to the hairs, cilia, inside the cochlea.
I?m surprised you need to crank the volume up so high. Try adjusting the transducers on the head as this can have a dramatic effect on conducted sound level. Perhaps you aren?t getting good contact or not in the best place, very small changes can make a big difference.
Also be aware of surrounding sounds, it?s easy to focus these out but they add, via the eardrums, to the overall level and might make you increase your volume.
Also, hearing damage isn?t just caused by high level sounds, it is total exposure of level and duration. So a lower level can be damaging if the exposure is for a longer time.

Kids are a lot easier to manipulate than those old and experienced. And so it has been through the ages.

Not convinced. People can often find it difficult to see that they are being manipulated.

I'm surprised that I'm allowed to write about it actually

It doesn't matter though, what I say here, right?

As long as you keep within the rules you can post what theories you like, right or wrong. If you fail the rule previously discussed the script (which hasn’t run recently) will pick them up.

As you say, it doesn’t really matter what you post as you have no regular or committed readers and the search engine here doesn’t easily help to find previous posts.

Sorry, I have a backlog of saved drafts/quotes I meant to reply to, but ran out of time. I’ll try to catch up.

They don't have any 'dimensions', and that was what the koan was for Colin

Not exactly a koan

And probabilities and statistics are, as far as I know, consistent, creating  'laws', by their own.

I dont see how they create laws. They describe what happens.
The normal distribution of height in a human population would still be there even if we didn’t have the tools to describe and analyse it.

You won't adapt to a major tipping, or even a tipping cascade.

These are not the big problem.
The question is have we passed the point of no return, where our lack of capabilities and resources can’t stop us getting to a tipping point!

How many 'dimensions' for a super position? Or a entanglement?

I don’t understand the question, I don’t know what you mean by dimensions.
For an electron we usually measure spin along the z axis, one dimension. Entanglement exists in 3 dimensional space, there is no time dimension because the correlations are time independent.
Do you mean bases?

Without 'laws' like this probabilities won't exist. And statistics should become meaningless

Again, I don’t understand what you are saying. Probabilities and statistics are only a way of describing the behaviour of what you are calling ‘laws’. Statistics can’t become meaningless as they only exist if there is something to measure repeatedly.
True that if a rose didn’t exist we wouldn’t have a word for it, but that’s not particularly enlightening.

I have to admit that Colin might be right. It's meaningless writing about it, won't change a thing.

That’s not what I meant.
You obviously put a lot of time into researching this so it’s a pity that it isn’t being read. Most of your viewers look at 2 or 3 posts and then drop out, occasionally they manage a page or 2. So it is less meaningless than pointless and a waste of time.
You have enough climate change material to make a good website and really influence people. However, you would need to keep on topic and structure it to make easier reading.

Theoretically one might want it that way but practically all geopolitics I've seen becomes a mix. I don't think you will get a correct picture without it Colin

The danger is not keeping clarity that they are separate causes. Lumping them together, even though they might appear together, blurs the true causes and leads to the conclusion that it’s all geopolitical. Which it is not.

As for economy I agree, it's a indivisible part of all geopolitics.

Although they often go together they are also often separate, not a good idea to consider them indivisible as it leads to woolly thinking.

At least one species of American starling buries nuts rather like a squirrel when they are plentiful, and returns to eat them in winter.

Jays also do this in uk

Wrens just happen to live in an environment where this sort of planning isn't needed.

No point burying worms

It depends on what you mean by control Colin. Every successful state need a structure and a 'control', what we call governments and our other structures.

I mean limiting the actions of others.
Yes, we hand some control to elected governments expecting them to use the minimum necessary controls to enable a functioning society. Problems arise when those controls mean unreasonable restrictions eg limiting access to information or differing opinions. Bigger problems arise when a state decides to control another state, or is threatened by their unwillingness to be controlled; that can lead to war eg Vietnam as you mentioned.

if a wren eats half a worm, the worm will quickly grow into a full worm again. But wrens don't appear to ever do that. They always eat them whole.

A worm in the crop is worth two in the ground.

It's definitely about geopolitics.

I would say more about econopolitics and control.

Ukrainians probably want the same as me, peace and quiet

Looking at their postwar history it looks as though they also wanted cultural change and the ability to decide their own future. That is anathema to any organisation based on control.
