I can't remember if any of Ilya Prigogne's books are well written or accessible enough to be on this list or whether I pieced together an understanding of his ideas from him and Morowitz.
I can't remember in which book I learned of Morowitz's characterization of life as a cyclic phenomenon running on energy flow. Or his cycling theorem that states that energy flowing through a finite system induces chemical cycles.

Correct Protein Function Depends On Sequence and RATE Of Folding. Genes Code For BOTH!
New work hints at a reason why the genetic code is redundant! Needs to code not only for sequence of aminos but also the RATE at which the sequence gets translated to get the right shape and right function. Clever! Explainer:
Reading genes with 4 possible bases 3 at a time can lead to 4x4x4 possible words, translated to 64 possible amino acids to build proteins. Yet biology uses only 20! Presently most aminos are represented by 2 to 6 possible base combos. Redundant! or is it? 1/n
Protein function is dependent on shape. We knew shape is dependent on amino acid sequence specified in genes. But it's not like computer code, it's also physics, so shape is also dependent on RATE of building a protein. Cells need to regulate THAT. wait for it... 2/n
The redundancy in the genetic code allows for this. For each amino, different codons that code for it can have a different tRNA molecule translate the code to amino. Different versions of tRNA for each amino are made in varying amounts. 3/n
Needing a tRNA of low abundance will slow down the protein building process. By coding for a rare tRNA or abundant one the genes can also code for the RATE of translation (=building) of the protein and therefore its correct finally folded shape. 4/4

Or Should I flesh out this story? the Deep Story behind the recent hype on possible life on Venus
somehow we have to get across the very buzzy HUMAN DRAMA of ... so the venus announcement is that they used these impressive peices of machinery to listen to radio waves traveling through atmosphere of venus and we CAN determine that it's diff shaped molecules DANCING!
and..the HISTORY we gotta get across that science is a LOONG HAUL story, not the latest fashion buzz, not the quick salvation from aliens. it took 150 years of really hard work, confusing work, to understand that stuff is made of dancing molecules, hell, Boltzman died for it
so the sense of mastery, the precision craftwork it takes to work with these radio detectors and have CONFIDENCE we've detected a particular molecule dancing in the atmosphere of what looks like a DOT in the sky!
we have to keep talking about how science is this grand slow collective endeavour of 1000s of people carefully taking apart and putting together an understanding of results from many different realms to get them to fit together into a stronger and more wideranging world view
our job is to explore the philosophical implications of the question "what is life". We don't know what life is! we don't know how life fits in with the rest of physics and chemistry! is it totally alien? is it a phenomenon on a continuum of complexity possible? etc...
we have to portray how amazing it would be if we even ONLY found, say, something like the reverse krebs cycle happening on venus and nothing else. putting life in the continuum of levels of complexity of chems instead of it being a miracle invented by alien space dude, god.
Writing Chemistry Poetry is hard! should I keep trying?
from whence new locks of flaxen hair?
how do deep gashes heal?
Are there weavers in her scalp?
factories made of steel?
i marvel that a crawling babe
from its mother's womb can come
grown only by the food she eats
how is this transformation done?
we've looked within by microscope
and still it's mystery
till by centuries of dirty labor
we learned whats chemistry
we watched microscopic urchin egg
split to two then four then eight...
till more and more form embryo
the cells move 'round and differentiate
it is the way with all living beings
from cells do other cells become
and we've found single cells in ponds
behave like miniature animals
what are these living sacklike beings?
more cells inside em ad finitum?
no! we discovered molecules
that run round and round and exite em.
two hundred years of fruitful confusion
in laboratories of fire and glass
we learned to weigh the very air
completing accounts for chem reactions
lucretius imagined molecules
that made everything we know
it took till 1922
that by measuring we could show
jiggling in the palm of your hand
the number of atoms boggles the mind
six hundred thousand billion billion
of 92 different kinds
each living amoeba single cell
contains a swirling multitude
of molecules who's number exceeds
all the bricks in new york city
these molecules are more than bricks
they jiggle and swirl all around
sensing each other upon collision
making decisions of what to do
springloaded mechanisms guided by equations
join each to each or disband
building structures quite complex
and dynamic patterns profound
thru networks of these logical decisions
protein molecules in your cells
engage in elaborate computations
coordinate behavior of a complex being
....
a poem on molecules?
Molecular Zine I wrote on a folded piece of paper once
Sometimes the world seems so solid. but then it rains on a cold spring morning and you go out for a jog anyway and you notice your breath exhale as mist and you wonder am I water too?
and you wonder so hard you do some chemistry and find your breath does condense into water on a cold window pane and further.. if you breath into a solution of slaked lime your breath can precipitate out as limestone... some of your breath can turn into rock?
and the plants, the tall firm trunks of wood, all made of breath, can be burnt back into breath like you can when you are finnished.
and if you wonder so hard at such transformations that you math the hell out of them like Einstein and Perrin did and decide that breath is a billion billion molecules who's collisions can be cleverly counted
and you patiently count and count and yes... 623,000,000,000,000,000,000,000 of them in the palm of your hand and you look deeper and deeper and you watch yourself when you were an
egg
in your mother's womb and watch that tiny amoeba suckle at her womb and grow so lush it splits into two amoebas and then 4 and 8 and 16 and 32 and 64 and 128 and 256 and 512 and 1024 and 2048 and everyday it's
growing, 4096... 262164...524188... 1048576... 2 million, 4 million amoebas bustling and hustling and building and learning to dance eyeballs and heartbeat and muscles and lungs
and 268435456... 536870912 and a billion and 2 billion and 4 billion and a vast nation of amoebas connecting and conversing and inventing and talking up a whole brainful of thoughts and desires to look inside themselves asking what is this amoeba
life? with its hustling and bustling of 623,000,000,000,000,000 molecules each amoeba is and how does it live? more molecular robots than there are bricks in all of New York City
in motion and jiggling and wiggling and dancing with each other, calculating... and calculations come together to make comparisons, and counting and differentiating and deciding and sifting and sorting through
random jiggling quantum fluctuations of the universe to create nano transformer robots a society of them a clever squaredance of one hundred different dances with a
thousand robot dancers in each one and they all swirl together so that out of the crowd of jostling robots they can recreate any dance and spilling this tale out from scratch with pen and paper surely
got hopelessly lost in a bustling confederation of a trillion squaredances of a hundred thousand billion dancers each and it takes more than 12 small pages to comprehend life.
