Homo liber nulla de re minus quam de morte Based on lectures delivered under the auspices of cogitat; et sfhrodinger sapientia non mortis sed vitae the Dublin Institute for Advanced Studies at meditatio est.
Trinity College, Dublin, in February This is regarded as a matter of noblesse oblige. For the present purpose I beg to renounce This little book arose from a course of public the noblesse, if any, and to be the freed of the lectures, delivered by a theoretical physicist to an ensuing obligation. My excuse is as follows: We audience of about four hundred which did not have inherited from our forefathers the keen substantially dwindle, though warned at the longing for unified, all-embracing knowledge.
But be utilized. The reason for this was not that the the spread, both in and width and depth, of the subject was simple enough to be iw multifarious branches of knowledge by during without mathematics, but rather that kife was much the last hundred odd years has confronted us too involved to be fully accessible to with a queer dilemma. We feel clearly that we mathematics.
Another feature which at least are only now beginning to acquire reliable induced a semblance of popularity was the material achrodinger welding together the sum total of all lecturer's intention to make clear the fundamental that is known into a whole; but, on the other idea, which hovers between biology and physics, hand, it has become next to impossible for a to both the physicist and the biologist.
For single mind fully to command more than a small actually, in spite of the variety of topics specialized portion of it. I can see no other involved, the whole enterprise lifr intended to escape from this dilemma lest our true who aim convey one idea only -one small comment on a be lost for ever than that schrodonger of us should large and important question.
In order not to lose venture to embark on a synthesis of facts lifee our way, it may be useful to outline the plan very theories, albeit with second-hand and incomplete briefly in advance. The large and important and knowledge of some of them -and at the risk of very much discussed question is: How can the sfhrodinger fools of ourselves.
So much for my events in space and time which take place apology. The difficulties of language are not cshrodinger the spatial boundary of a living organism negligible. Schrodihger native speech is a closely fitting be accounted for by physics and chemistry?
The garment, and one never feels quite at ease when preliminary answer which this little book will it is not immediately available and has to be endeavor to expound and establish can be replaced by another. My thanks are due to Dr summarized as follows: The obvious inability of Inkster Trinity College, Dublinto Dr Padraig present-day physics and chemistry to account for Browne St Patrick's College, Maynooth yb, such events is how to stop perspiration under arms naturally reason at all for doubting that last but not least, to Mr Lice.
They were they can be accounted for liffe those sciences. Organic chemistry, indeed, amply accounted for. Today, thanks to the in investigating more and more complicated how to treat a dog with a cut work of biologists, mainly of molecules, has come very much nearer to that geneticists, during the last thirty or forty years, 'aperiodic crystal' which, in my opinion, is the enough is known about the actual material material carrier of life.
And therefore it is small structure of organisms and about their wonder that scgrodinger organic chemist has already functioning to state that, and to tell precisely made large and important contributions to the why present-day physics and chemistry bj not problem of life, whereas the physicist has made possibly account for what happens in space and next to none. I experimental and theoretical research. Yet the propose to develop first what you might call 'a difference which I have just termed fundamental naive physicist's ideas about organisms', that is, is lofe such a kind that it might easily appear slight the ideas which might arise in the mind of a to pddf except a physicist who is thoroughly physicist who, after having learnt his physics imbued with the knowledge that the laws of and, whxt especially, the statistical foundation of physics and chemistry are statistical throughout.
It is well-nigh contributions to the question. It will turn out that unthinkable that the laws cshrodinger regularities thus he can.
The next step must be to f compare his discovered should happen to apply immediately theoretical anticipations with the biological facts. The non-physicist cannot be expected appreciably amended. Even if I should be right in this, I do just used. To give the statement life and colour, not lief whether my way of approach is really let me anticipate what will be explained in much the best and simplest. But, in short, it was mine. And I could not part of a living cell-the chromosome fibre may find any better or clearer way towards the goal suitably be called an aperiodic crystal.
In physics than my own crooked one. To what is a wigi board used for nature puzzles his wits. Yet, compared begin with, they are very small whaat.
Every with the aperiodic crystal, they are rather plain little piece of matter handled in everyday life and dull. The difference in structure is of the contains an enormous number of them. Many same kind as that between an ordinary wallpaper examples have been devised to bring this fact in which the same pattern is pxf again and home to an audience, none of them more again in regular periodicity and a masterpiece of impressive than the one used by Lord Kelvin: embroidery, say a Raphael tapestry, which shows Suppose that you could mark the molecules in a no dull repetition, but schrodinyer elaborate, coherent, glass of water; then pour the contents of the glass meaningful design traced by the great master.
Must that be so? Is there an throughout the seven seas; if then you took a intrinsic reason for it? Can we trace back this glass of water anywhere out of the ocean, you state of affairs to some kind of first principle, in would find in it about a hundred of your marked order to ascertain and to understand why nothing molecules.
Now this, for schrodknger, is a what are the health benefits of cranberries which yellow light.
The comparison is significant, the physicist is able to clear up completely. The because the wave-length roughly indicates the how to patch euro truck simulator 2 to all the queries is in the affirmative.
Now, why are schridinger so If it were not so, if we were organisms so small? Clearly, the question is an evasion. For it schrodnger that a single atom, or even a few atoms, is not lifee aimed at the size of the vy. It is could make a perceptible impression on our concerned with the size of organisms, more senses -Heavens, what would life be like! To particularly with the size of our own corporeal stress one point: an organism of that kind would selves. Indeed, the atom is small, when referred most certainly not be capable of developing the to our civic unit of length, say the yard or the kind of orderly thought which, after passing metre.
In atomic physics one is accustomed to through a long sequence of earlier stages, use the so-called Angstrom abbr. Awhich is ultimately results in forming, among many other the pef part of a metre, or in decimal notation ideas, the idea of an atom.
Even though we select 0. Atomic diameters range this one point, the following considerations between 1 and 2A. Now those civic units in would essentially apply also to the functioning of relation to which whhat atoms are so small are organs schodinger than the brain and the sensorial closely related to the size of our bodies. There is system.
Nevertheless, the one and only thing of a story tracing the yard back to the humour of an paramount interest to us in ourselves is, that we English king whom his councillors asked what feel and think and perceive.
To the physiological pdr to adopt -and he stretched out schroidnger arm process which is responsible for thought and sideways and said: 'Take the distance from the sense all the others play an auxiliary part, at least middle of my chest to my fingertips, that will do from the human point of view, if not from that of all right.
Moreover, it will our purpose. The king would naturally I indicate greatly facilitate our task to choose for a length comparable with that of his own body, investigation the process which is closely knowing that anything else would be very accompanied by subjective events, even though inconvenient. With all his predilection for the we are ignorant of the true nature of this close Angstrom unit, the physicist prefers to be told parallelism.
Indeed, in my view, it lies outside that his new suit will require six and a half yards the range of natural science and very probably of of tweed -rather than sixty-five thousand human understanding altogether. Whay are thus millions of Angstroms of tweed. It thus being faced with the following question: Why should settled that our question really schrodigner at the ratio an organ like our brain, with the sensorial system of two lengths -that of our body and that of the attached to it, of necessity consist of an atom - with an incontestable ldf of enormous number of atoms, in order that its independent existence on the side of the atom, physically changing state should be in close and the question truly reads: Why must our bodies be intimate correspondence with a highly developed so large compared with the atom?
I can imagine thought? On what grounds is the latter task of the that many a keen student of physics or chemistry said organ incompatible with being, as a whole may have deplored the fact that everyone of our or in some of its peripheral parts which interact sense organs, forming a more or less substantial directly with the environment, a mechanism part of our body and hence in view of the sufficiently refined and sensitive to respond to magnitude of the said ratio being itself and register the impact of a single atom from composed of innumerable atoms, is much too outside?
The reason for this is, that what we call coarse to be affected by the impact of a single thought 1 is itself an orderly thing, and 2 can atom.
We cannot see or feel or hear the single only be applied to material, i. Lufe hypotheses with regard to them differ experiences, which have a certain degree of widely from the immediate findings of our gross orderliness.
This has two consequences. An entire newcomer with my thought must be a very well-ordered should not expect to obtain schrodinnger the following organization, and that means that the events that few pages a full understanding and appreciation happen within it must obey strict physical laws, of the subject, which is associated with the at least to a very high degree of accuracy.
If you fill bodies from outside, schgodinger correspond to the an oblong quartz tube with oxygen gas and put it perception and experience of the corresponding into a magnetic field, you find that the gas is thought, forming its material, as I have called it.
The magnetization is due to the fact Therefore, the physical interactions between our that the oxygen molecules are little magnets and system and others must, as a rule, themselves tend to orientate themselves parallel to the field, possess a certain degree of physical orderliness, like a compass needle. But you must not think that is ny say, they too must obey strict physical that they actually all turn parallel.
For if you laws to a certain degree of accuracy. This is a particularly clear And why could all this not be fulfilled in the case example of a whah statistical law. The of an organism composed of a moderate number orientation the field tends to produce is of atoms only and sensitive already to the impact continually counteracted by the heat motion, of one or a few atoms only?
How to do short scene hair for guys we know which works for random orientation. The effect all atoms to perform all the time a completely of this striving is, actually, only a small disorderly heat motion, which, so to speak, preference for acute over obtuse angles between opposes itself to their orderly behaviour and does the dipole axes and the field. Though the single not allow the events that happen between a small atoms change their orientation incessantly, they number of atoms to enrol themselves according produce on the average owing to their enormous to any recognizable laws.
Only in the co- number a constant small preponderance of operation of an enormously large number pff orientation in the direction of the field and atoms do statistical laws begin to operate and proportional to it.
This ingenious explanation is control the behaviour of these assemblies with an due to the French physicist P.
It can accuracy increasing as the number of atoms be checked in the following way. If the observed involved increases. It is in js way that the weak magnetization is really the outcome of rival events acquire truly orderly features.
All the tendencies, namely, the magnetic field, which physical and chemical laws that are known to aims at combing all the molecules parallel, and play an important part in the life of organisms the heat motion, which makes for random are of schrodiinger statistical kind; any other kind of orientation, then it wwhat to be possible to lawfulness and orderliness that one might think increase the magnetization by weakening schrldinger of is being perpetually disturbed and made heat motion, that is to say, by lowering the inoperative by the unceasing heat motion of the temperature, instead of reinforcing the field.
That atoms. In this case we no this condition of things -a condition which in longer iss that double the scurodinger strength will modern physics and chemistry is as fundamental double the magnetization, but that the latter will as, say, the fact that organisms are composed of increase less and less with increasing field, cells is in biology, or as Newton's Law in approaching what is called 'saturation'.

In many countries, it was issued as the second single from the album, in February , becoming a top-ten hit in the United States, Canada and elsewhere, and topping singles charts in Australia and Switzerland. Harrison co-produced the recording with Phil Spector , whose Wall of Sound production also employed a prominent string arrangement by John Barham and multiple acoustic rhythm guitars, played by Harrison's fellow Apple Records signings Badfinger. An uptempo composition in the soul genre, "What Is Life" is one of several Harrison love songs that appear to be directed at both a woman and a deity.
Built around a descending guitar riff , it is one of Harrison's most popular compositions and was a regular inclusion in his live performances. Rolling Stone magazine has variously described it as a "classic"  and an "exultant song of surrender". Ronnie Aldrich , the Ventures and Shawn Mullins are among the other artists who have covered the track. Even before his temporary departure from the Beatles in January documented in the song " Wah-Wah " ,  their Apple Records label was an "emancipating force" for Harrison from the creative restrictions imposed on him within the band, according to his musical biographer, Simon Leng.
In his autobiography, I, Me, Mine , Harrison describes it as having been written "very quickly" and recalls that he thought it would be a perfect, "catchy pop song" for Preston to record. Harrison biographer Simon Leng describes "What Is Life" as " Motown -spiced" and a comparatively rare example of its composer's willingness to embrace the role of "entertainer" in his songwriting.
The lyrics have a universal quality, being both simple and uplifting. Theologian Dale Allison finds no religious content in "What Is Life" but comments that the "failure of words to express feelings" implied in the opening line "What I feel, I can't say" is a recurring theme in Harrison's spiritual songs. The second verse repeats what Inglis refers to as the "somewhat confusing promise" from Harrison in lines 3 and 4 should his love be "rejected": .
What I know, I can do If I give my love out to everyone like you But if it's not love that you need Then I'll try my best to make everything succeed. The track opens with Harrison playing the fuzztone guitar riff,  which is then joined by Radle's bass and "churning" rhythm guitar from Clapton, before Gordon's drums bring the full band in.
On "What Is Life", Spector provided what music critic David Fricke terms "echo-drenched theater", in the form of reverb -heavy brass, soaring strings arranged by John Barham and "a choir of multitracked Harrisons".
After recording the album's backing tracks with Spector, Harrison carried out most of the overdubbing without him, working at Trident Studios with former Beatles engineer Ken Scott.
While describing the initial impact of All Things Must Pass , author Robert Rodriguez includes the song as an illustration of how the depth of Harrison's talents had been "hidden in plain sight" behind John Lennon and Paul McCartney during the Beatles' career.
The front of the single's US picture sleeve consisted of a photo of Harrison playing guitar inside the central tower of Friar Park. The poster featured a painting of the Hindu deity Krishna watching a group of naked maidens beside a bathing pond. As with the parent album, the single was a commercial and critical success. Reviewing the reissue of All Things Must Pass , for Rolling Stone , James Hunter wrote of how the album's music "exults in breezy rhythms", among which "the colorful revolutions of 'What Is Life' Writing in the book 1, Recordings to Hear Before You Die , author Tom Moon refers to "the upbeat single 'What Is Life'" as an example of how Harrison "grabs what he needs from his old band — that insinuating hook sense — and uses it to frame an utterly comfortable metaphysical discourse".
Galluci wrote of the track having "a giant pop hook as its guide" as well as "the catchiest chorus Harrison ever penned". I will never forget the tingle I felt while standing, when I was around 11, at a jukebox in a diner in early-'70s Ann Arbor, dropping a coin into the machine to play a song that was still new to me: "What Is Life".
That descending guitar line crackled out of the speaker like a sassy, jagged lightning bolt. The drums were as thunderous as Led Zeppelin 's, only it was romantic thunder, and Harrison's yearning vocals rode atop Phil Spector's now-electrified wall of sound like a jubilant cry of triumph: He had broken free!
Free of the Beatles, of the '60s, of the material world It was one of the most ecstatic things I'd ever heard, and ever would hear. It was the spirit of love speaking through George Harrison, as it would speak through him throughout that album. An alternative studio version of "What Is Life" was one of the five bonus tracks included on the remaster of All Things Must Pass.
So all I could do on the [initial] take was to give the band the cue line — the first line of each verse — and then go back to playing that riff. So that rough mix without the vocal — I'd forgot all about it …"  [nb 5].
Coinciding with the release of the Apple Years —75 box set in September , Harrison's widow and son, Olivia and Dhani Harrison , held an online competition in which filmmakers were invited to create a video clip for "What Is Life". A live version of the song, recorded with Eric Clapton and his band in December ,  is available on Harrison's album Live in Japan album.
Released as a single in some countries, this version reached the UK top 20 in March ,   peaking at number The following musicians are believed to have played on "What Is Life":  .
