 Hi John,

 If I understand your question, I think I do have a general idea of
 what I, informally, associate with life. I always tend to imagine some
 self-contained system that is capable of procuring sources of energy
 in its environment and use that energy to, more or less, maintain it's
 structure.


 For 'life', in contrast to 'being alive', I'd add reproduction. That's
 the
 real defining characteristic of life.

 I tend to agree, but maybe we're on the verge of transcending that. If
 we clone some organism is it still reproduction? What if we tweak the
 DNA?


 Sure. It doesn't even have to involve DNA.  As Bruno pointed out cigarettes
 reproduce too.

Ok!



 None of the robots that I've seen so far fit this ideal. Even if they
 can look for an outlet and recharge their batteries, they are not
 capable of deeply fixing themselves. They cannot use that energy to
 rebuild some part of themselves that is damaged.


 And your ability to do that is quite limited.  So if a robot could
 replace a
 damaged limb with one from a supply cabinet it'd be one up on us.

 Sure, but I feel there's something to the deep mechanisms of living
 organisms, as I stated in my reply to John. I'm waxing poetic a bit
 here, sorry!


 What's 'deep' is that there's a whole complex interdependent system of life.
 You couldn't maintain your body if there were not all those plants and
 animals from which you can get pre-built proteins. Just like cigarettes
 couldn't reproduce without tobacco farmers.

Also ok :)

Telmo.

  However... (there is always one):
 You haven't seen ALL and the BEST robots, have you?

I admit my ignorance, of course.

 Batteries are some
 primitive gadgets for a starting line of development. What is deeply?

It's akin to fractal in the sense I'm thinking. Organs, tissues,
cells, mitochondria -- or whatever the equivalent of these things are.

 And
 what is that 'energy' you invoke? (And: YES, they CAN rebuild damaged parts
 from their environment (Rosen's MR) if they have the tools. (Just arrived
 Brent's similar remark to the list).

Sure, but life is organised in a way that is almost recursive. It
rebuilds across scales. I'm not being very rigorous here, but I get
the sense you're asking about what I feel life to be.

 Why do you hold 'computational resources' as fundamental to being alive?

Some limited resource, otherwise there's no creative tension. No
adaptive niches, for example.

 Computation is a human mental peculiarity - an 'evolved resource' by 'being
 alive' (whatever that means). How 'bout Bruno's Universal Machine?

I like Bruno's Universal Machine. If he's right, I think this machine
is at a meta level in relation to what we're discussing. But are you
asking perhaps if I think this machine is alive?

 There are so many misconceptions about 'life' (mainly HUMAN) floating
 around. Religious ones e.g. fix the beginning of it at conception of an
 egg and a sperm, (my question to that: show me a dead sperm and a dead egg
 the combining of which will START a human life - consequently those
 ingredients have to be 'alive' = having that darn 'life' in them to go on
 with it).

Not sure I agree here, but they are seeds for sure. And seed are very
interesting things.

 So I do not see an answer to my question in your reply. Try again?

I can keep trying.

 You don't have to reproduce to be alive though, and any chain reaction can
 be considered reproduction. To me, life is more about a quality of
 sensitivity which can produce intentionally sustained action against
 entropy.

That's an outdated conception of genes.  Genes are coding sequences in DNA.  They are not 
'superficially mapped' measurements.  They can be moved from one animal to another - c.f. 
rabbits that glow in the dark.


All 'networks' go infinite with branching further and further into more and more aspects 
(the genes not exempted) - it is a likely (human?) vision of the infinite complexity

So what?  We don't know a lot, but we know somethings.

Your distinction: can something be alive without life? Then my question stands. Could 
you describe 'being alive' without the concept of 'life'?


Being alive is well described by metabolism for maintenance and homeostasis.  So mules are 
definitely alive.  But there's no sharp distinction.  A robot that can recharge itself is 
a little bit alive too.  And a virus that can only metabolize by hijacking the mechanism 
of a cell is a little bit alive too.  But to have life you need reproduction - which is 
just maintenance at a species level.


Mules don't constitute life - no, mules constitute animals - a transition between a 
horse and an ass.


Between a jackass and a mare.  But they're not a transition, they're a hybrid.

Computation is a human mental peculiarity - an 'evolved resource' by '_being_ alive'

In the sense of writing equations and numbers down or doing arithmetic.  But in the more 
general sense of information processing, then computation is an essential part of 
metabolism.  It means taking stuff that's not you, and using code that describes your 
stuff, transform it into stuff that is you.

Hi John,

If I understand your question, I think I do have a general idea of
what I, informally, associate with life. I always tend to imagine some
self-contained system that is capable of procuring sources of energy
in its environment and use that energy to, more or less, maintain it's
structure.


For 'life', in contrast to 'being alive', I'd add reproduction. That's the real defining 
characteristic of life.




None of the robots that I've seen so far fit this ideal. Even if they
can look for an outlet and recharge their batteries, they are not
capable of deeply fixing themselves. They cannot use that energy to
rebuild some part of themselves that is damaged.


And your ability to do that is quite limited.  So if a robot could replace a damaged limb 
with one from a supply cabinet it'd be one up on us.


Brent



Simulation environments don't convince me either (and I've built a few
myself), because there's not real energy at stake. Now, if someone
created a program that was capable of programming itself in an effort
to try to maximise it's ability to achieve it goals by making the best
possible use of the available computational resources, then I might
eventually see it as being alive.

If you meant something else, please tell me.

Best,
Telmo.

 Scientists claim discovery of life coming to Earth from space
 Scientists from the University of Sheffield believe they have found life
 arriving to Earth from space after sending a balloon to the stratosphere.’
 After it landed, scientists discovered that they had captured a diatom
 fragment and some unusual biological entities from the stratosphere, all of
 which are too large to have come from Earth.
 Other scientists disagree, as noted here: New Alien Life Claim Far from
 Convincing, Scientists Say
 The team, led by Professor (Hon. Cardiff and Buckingham Universities) Milton
 Wainwright, from the University’s Department of Molecular Biology and
 Biotechnology found small organisms that could have come from space after
 sending a specially designed balloon to 27km into the stratosphere during
 the recent Perseid meteor shower.
 Professor Wainwright said: “Most people will assume that these biological
 particles must have just drifted up to the stratosphere from Earth, but it
 is generally accepted that a particle of the size found cannot be lifted
 from Earth to heights of, for example, 27km. The only known exception is by
 a violent volcanic eruption, none of which occurred within three years of
 the sampling trip.
 “In the absence of a mechanism by which large particles like these can be
 transported to the stratosphere we can only conclude that the biological
 entities originated from space. Our conclusion then is that life is
 continually arriving to Earth from space, life is not restricted to this
 planet and it almost certainly did not originate here.”
 Professor Wainwright said the results could be revolutionary: “If life does
 continue to arrive from space then we have to completely change our view of
 biology and evolution,” he added. “New textbooks will have to be written!”
 Professor Wainwright said stringent precautions had been taken against the
 possibility of contamination during sampling and processing, and said the
 group was confident that the biological organisms could only have come from
 the stratosphere.
 The group’s findings have been published in the Journal of Cosmology (open
 access) and updated versions will appear in the same journal, a new version
 of which will be published in the near future. Professor Chandra
 Wickramasinghe of the Buckingham, University Center for Astrobiology (of
 which Professor Wainwright is an Honorary Fellow) also gave a presentation
 of the group’s findings at a meeting of astronomers and astrobiologists in
 San Diego last month.
 Professor Wainwright added: “Of course it will be argued that there must be
 an, as yet, unknown mechanism for transferring large particles from Earth to
 the high stratosphere, but we stand by our conclusions. The absolutely
 crucial experiment will come when we do what is called ‘isotope
 fractionation’. We will take some of the samples which we have isolated from
 the stratosphere and introduce them into a complex machine – a button will
 be pressed. If the ratio of certain isotopes gives one number then our
 organisms are from Earth, if it gives another, then they are from space. The
 tension will obviously be almost impossible to live with!”
 The research was conducted by Professor (Hon. Cardiff and Buckingham
 Universities) Milton Wainwright from the University of Sheffield, Chris Rose
 and Alex Baker from the University of Sheffield’s Leonardo Centre for
 Tribology and Professor Chandra Wickramasinghe Director of the Centre for
 Astrobiology, University of Buckingham.

2013-09-21 Thread Chris de Morsella
Damn there goes pangea lol

I saw this yesterday on Kurzweil's blog and went back to the post to check
it and saw they had put out this UPDATE to the original, which I am pasting
below.
-Chris

UPDATE Sept. 21, 2013 1:00 EDT

In a blog post on KurzweilAI, theoretical biologist Dr. Richard Gordon
called these conclusions into question, noting that just one broken diatom
shell was found (not statistically impressive), no controlled experiment was
reported in a dusty environment, collection methods and lab conditions were
unspecified, and the study failed to provide data on the condition of the
balloon-borne equipment.

He also noted that there is literature on how hurricanes and storms move
diatoms through the atmosphere, and that there have been several mechanisms
suggested for the transfer of particles to the upper atmosphere. For
example, bacteria and other biological materials are common components of
cloud condensation nuclei.

Professor Wainwright said: Most people will assume that these biological
particles must have just drifted up to the stratosphere from Earth, but it
is generally accepted that a particle of the size found cannot be lifted
from Earth to heights of, for example, 27km. The only known exception is by
a violent volcanic eruption, none of which occurred within three years of
the sampling trip.

In the absence of a mechanism by which large particles like these can be

entities originated from space. Our conclusion then is that life is
continually arriving to Earth from space, life is not restricted to this
planet and it almost certainly did not originate here.

continue to arrive from space then we have to completely change our view of
biology and evolution, he added. New textbooks will have to be written!

Scientists claim discovery of life coming to Earth from space
Scientists from the University of Sheffield believe they have found life 
arriving to Earth from space after sending a balloon to the stratosphere.’
After it landed, scientists discovered that they had captured a diatom fragment 
and some unusual biological entities from the stratosphere, all of which are 
too large to have come from Earth.
Other scientists disagree, as noted here: New Alien Life Claim Far from 
Convincing, Scientists Say
The team, led by Professor (Hon. Cardiff and Buckingham Universities) Milton 
Wainwright, from the University’s Department of Molecular Biology and 
Biotechnology found small organisms that could have come from space after 
sending a specially designed balloon to 27km into the stratosphere during the 
recent Perseid meteor shower.
Professor Wainwright said: “Most people will assume that these biological 
particles must have just drifted up to the stratosphere from Earth, but it is 
generally accepted that a particle of the size found cannot be lifted from 
Earth to heights of, for example, 27km. The only known exception is by a 
violent volcanic eruption, none of which occurred within three years of the 
sampling trip.
“In the absence of a mechanism by which large particles like these can be 
transported to the stratosphere we can only conclude that the biological 
entities originated from space. Our conclusion then is that life is continually 
arriving to Earth from space, life is not restricted to this planet and it 
almost certainly did not originate here.”
Professor Wainwright said the results could be revolutionary: “If life does 
continue to arrive from space then we have to completely change our view of 
biology and evolution,” he added. “New textbooks will have to be written!”
Professor Wainwright said stringent precautions had been taken against the 
possibility of contamination during sampling and processing, and said the group 
was confident that the biological organisms could only have come from the 
stratosphere.
The group’s findings have been published in the Journal of Cosmology (open 
access) and updated versions will appear in the same journal, a new version of 
which will be published in the near future. Professor Chandra Wickramasinghe of 
the Buckingham, University Center for Astrobiology (of which Professor 
Wainwright is an Honorary Fellow) also gave a presentation of the group’s 
findings at a meeting of astronomers and astrobiologists in San Diego last 
month.
Professor Wainwright added: “Of course it will be argued that there must be an, 
as yet, unknown mechanism for transferring large particles from Earth to the 
high stratosphere, but we stand by our conclusions. The absolutely crucial 
experiment will come when we do what is called ‘isotope fractionation’. We will 
take some of the samples which we have isolated from the stratosphere and 
introduce them into a complex machine – a button will be pressed. If the ratio 
of certain isotopes gives one number then our organisms are from Earth, if it 
gives another, then they are from space. The tension will obviously be almost 
impossible to live with!”
The research was conducted by Professor (Hon. Cardiff and Buckingham 
Universities) Milton Wainwright from the University of Sheffield, Chris Rose 
and Alex Baker from the University of Sheffield’s Leonardo Centre for Tribology 
and Professor Chandra Wickramasinghe Director of the Centre for Astrobiology, 
University of Buckingham.
