Lambda Quotes

Without a doubt, Einstein’s greatest blunder was having declared that lambda was his greatest blunder.

Fourth is Lambda, the cosmological constant, which determines the acceleration of the universe.

So lambda’s sole job was to oppose gravity within Einstein’s model, keeping the universe in balance, resisting the natural tendency for gravity to pull the whole universe into one giant mass.

Et puis, comme à chaque fois, c'est plus simple d'acquiescer et de ne rien dire pour éviter les problèmes en pensant qu'un court moment de joie apportera comme par magie le bonheur à long terme.

Le monde était de trop. On n'en avait clairement pas besoin. On n'avait pas grand chose... Mais on était tout. Il ne nous manquait rien. On riait trop fort. On riait pour des choses nulles trop longues à expliquer, vous savez, celles où « il faut être là pour comprendre. » Il fallait être là pour comprendre. Et ça, pour être là, j'étais là. C'était une alchimie rare, évidente. Nous avions l'impression de faire briller le soleil. Qu'est-ce qu'on était beaux.

But since we’re on the topic of identity and narrative voice - here’s an interesting conundrum. You may know that The Correspondence Artist won a Lambda Award. I love the Lambda Literary Foundation, and I was thrilled to win a Lammy. My book won in the category of “Bisexual Fiction.” The Awards (or nearly all of them) are categorized according to the sexual identity of the dominant character in a work of fiction, not the author. I’m not sure if “dominant” is the word they use, but you get the idea. The foregrounded character. In The Correspondence Artist, the narrator is a woman, but you’re never sure about the gender of her lover. You’re also never sure about the lover’s age or ethnicity - these things change too, and pretty dramatically. Also, sometimes when the narrator corresponds with her lover by email, she (the narrator) makes reference to her “hard on.” That is, part of her erotic play with her lover has to do with destabilizing the ways she refers to her own sex (by which I mean both gender and naughty bits). So really, the narrator and her lover are only verifiably “bisexual” in the Freudian sense of the term - that is, it’s unclear if they have sex with people of the same sex, but they each have a complex gender identity that shifts over time. Looking at the various possible categorizations for that book, I think “Bisexual Fiction” was the most appropriate, but better, of course, would have been “Queer Fiction.” Maybe even trans, though surely that would have raised some hackles. So, I just submitted I’m Trying to Reach You for this year’s Lambda Awards and I had to choose a category. Well. As I said, the narrator identifies as a gay man. I guess you’d say the primary erotic relationship is with his boyfriend, Sven. But he has an obsession with a weird middle-aged white lady dancer on YouTube who happens to be me, and ultimately you come to understand that she is involved in an erotic relationship with a lesbian electric guitarist. And this romance isn’t just a titillating spectacle for a voyeuristic narrator: it turns out to be the founding myth of our national poetics! They are Emily Dickinson and Walt Whitman! Sorry for all the spoilers. I never mind spoilers because I never read for plot. Maybe the editor (hello Emily) will want to head plot-sensitive readers off at the pass if you publish this paragraph. Anyway, the question then is: does authorial self-referentiality matter? Does the national mythos matter? Is this a work of Bisexual or Lesbian Fiction? Is Walt trans? I ended up submitting the book as Gay (Male) Fiction. The administrator of the prizes also thought this was appropriate, since Gray is the narrator. And Gray is not me, but also not not me, just as Emily Dickinson is not me but also not not me, and Walt Whitman is not my lover but also not not my lover. Again, it’s a really queer book, but the point is kind of to trip you up about what you thought you knew about gender anyway.

All our puzzles about whether or not lambda exists and, if so, what is responsible for giving it such a strange value, are like questions about the inflationary scalar field's potential landscape. Why is its final vacuum state so fantastically close to the zero line? How does it 'know' where to end up when the scalar field starts rolling downhill in its landscape? Nobody knows the answer to these questions. They are the greatest unsolved problems in gravitation physics and astronomy. The nature of their answers could take many forms. There could exist some deep new principle that links together all the different forces of Nature in a way that dictates the vacuum levels of all the fields of energy that feel their effects. This principle would be unlike any that we know because it would need to control all the possible contributions to lambda that arise at symmetry breakings during the expansion of the Universe. It would need to control physics over a vast range of energies.

Instead, this time he made what he called a “slight modification” to his theory. To keep the matter in the universe from imploding, Einstein added a “repulsive” force: a little addition to his general relativity equations to counterbalance gravity in the overall scheme. In his revised equations, this modification was signified by the Greek letter lambda, , which he used to multiply his metric tensor gμv in a way that produced a stable, static universe. In his 1917 paper, he was almost apologetic: “We admittedly had to introduce an extension of the field equations that is not justified by our actual knowledge of gravitation.” He dubbed the new element the “cosmological term” or the “cosmological constant” (kosmologische Glied was the phrase he used). Later,* when it was discovered that the universe was in fact expanding, Einstein would call it his “biggest blunder.” But even today, in light of evidence that the expansion of the universe is accelerating, it is considered a useful concept, indeed a necessary one after all.14 During

spacetime is flat, that about 5 per cent of the mass of the Universe is in the form of baryons (including bright stars and gas and dust), some 27 per cent is in the form of cold dark matter, and 68 per cent is in the form of the lambda field, also known as dark energy.

You can use user data scripts and cloud-init directives or AWS OpsWorks lifecycle events to automatically set up new EC2 instances.[6] You can use simple scripts, configuration management tools like Chef or Puppet. AWS OpsWorks natively supports Chef recipes or Bash/PowerShell scripts. In addition, through custom scripts and the AWS APIs, or through the use of AWS CloudFormation support for AWS Lambda-backed custom resources

A functional interface in Java 8 is an interface with a single, abstract method. As such, it can be the target for a lambda expression or method reference.

Lambda expressions can only be assigned to functional interface references.

AWS Lambda is a compute service that lets you run code without provisioning or managing servers.

For even if we expunged all the matter in the Universe the lambda force could still exist, causing the universe to expand or contract. It was always there, acting on everything but unaffected by anything. It began to look like an omnipresent form of energy that remained when everything that could be removed from a universe had been removed, and that sounds very much like somebody's definition of a vacuum.

The laws of physics—as we understand them—depend on constants. If those constants were even slightly different, this universe would not exist—or would be of a different nature completely. For example, omega, the name the humans used for the universal density parameter, governs gravity and the expansion energy in the universe. The value of omega is one. If it were any stronger, the universe would have collapsed before life could have evolved. Alternatively, a lower value would have resulted in weaker gravity, potentially preventing stars from being formed. “The same is true for epsilon—the measure of the efficiency of fusion of helium from hydrogen. It’s also true for lambda—the cosmological constant. Most alarmingly, D, the number of spatial dimensions in spacetime, is three. If D were a different number—that is, if the spacetime we experience were defined by two or four dimensions, or any other number—the universe would be a radically different place.” “What are you telling me?” “It is highly probable that the grid we created isn’t the first one ever created.” “You believe this universe is a grid virtualization instance?” “I believe those are the terms we have that best describe it. However, it’s likely that the true nature of the universe is something else entirely, a reality we are unable to fully understand

Note that the hash function you pass will be compared by identity to that of other RDDs. If you want to partition multiple RDDs with the same partitioner, pass the same function object (e.g., a global function) instead of creating a new lambda for each one!

His long black hair and beard dripping sweat under a blistering Mediterranean sun, Portheus shouldered his lambda emblazoned hoplon, snatched up his spear and barked, “Axios, arm yourself!

[Currying] Named after Haskell Curry, one of the inventors of combinatory logic. Curry always insisted that he got the idea of using h from M. Schönfinkel’s [Sch24] (see [CF58, pp. 8, 10]), but most workers seem to prefer to pronounce ‘currying’ rather than ‘schönfinkeling’. The idea also appeared in 1893 in [Fre93, Vol. 1, Section 4].

Later Turing proved that Turing machines could compute exactly the same functions as lambda calculus, which proved that all three models of computation are equivalent. This is a truly remarkable result, considering how different the three models of computation are. In Church's 1941 paper he made a statement that is now known as the Church-Turing thesis: Any function that can be called computable can be computed by lambda calculus, a Turing machine, or a general recursive function. Recall the point that was made about functions describing relationships between numbers and models of computation describing functions. Well, the Church-Turing thesis is yet another level more fundamental than a model of computation. As a statement about models of computation, it is not subject to proof in the usual sense; thus, it is impossible to prove that the thesis is correct. Once could disprove it by coming up with a model of computation over discrete elements that could calculate things that one of the other models could not; however, this has not happened. The fact that every posed model of computation has always been exactly equivalent to (or weaker than) one of the others lends strong support to the Church-Turing thesis.

When one looks at the numbers, the situation becomes even more perplexing. The effect of lambda grows steadily with respect to the familiar Newtonian force of gravity as the Universe gets bigger. If it is only recently becoming the dominant force, after billions of years of expansion of the Universe, it must have started out enormously smaller than the Newtonian force. The distance of that final minimum energy level in Figure 8.14 from the zero line in order to explain the value of lambda inferred from the supernova observations is bizarre: roughly 10^-120 - that is, 1 divided by 10 followed by 119 zeros! This is the smallest number ever encountered in science. Why is it not zero? How can the minimum level be tuned so precisely? If it were 10 followed by just 117 zeros, then the galaxies could not form. Extraordinary fine tuning is needed to explain such extreme numbers. Extraordinary fine tuning is needed to explain such extreme numbers. And, if this were not bad enough, the vacuum seems to have its own defence mechanism to prevent us finding easy answers to this problem. Even if inflation does have some magical property which we have so far missed that would set the vacuum energy exactly to zero when inflation ends, it would not stay like that. As the Universe keeps on expanding and cooling it passes through several temperatures at which the breaking of a symmetry occurs in a potential landscape, rather like that which occurs in the example of the magnet that we saw at the beginning of the chapter. Every time this happens, a new contribution to the vaccum energy is liberated and contributes to a new lambda term that is always vastly bigger than our observation allows. And, by 'vastly bigger' here, we don't just mean that it is a few times bigger than the value inferred from observations, so that in the future some small correction to the calculations, or change in the trend of the observations, might make theory and observation fit hand in glove. We are talking about an overestimate by a factor of about 10 followed by 120 zeros! You can't get much more wrong than that.

It is the cosmological vacuum energy that contributes a repulsive lambda force to the gravitational force of Newton.

Lambda calculus has proven useful in describing, analyzing and implementing program- ming languages.

In particular, we can combine the chain() function with the contextlib.ExitStack() method to process a collection of files as a single iterable sequence of values. We can do something like this: from contextlib import ExitStack import csv def row_iter_csv_tab(*filenames): with ExitStack() as stack: files = [stack.enter_context(open(name, 'r', newline='')) for name in filenames] readers = [csv.reader(f, delimiter='\t') for f in files] readers = map(lambda f: csv.reader(f, delimiter='\t'), files) yield from chain(*readers)

... we [humans] are an organic life form that became too sentient of our own existence. When we reached the moment we began to questionise our origin and our demise, that was the moment we should have stop evolving.

J'admire Shakespeare. Son théâtre est à l'image de la vie, qui juxtapose sans fausse honte le rire et les larmes, l'amour et la haine, la religion et le sexe. Les tragédies les plus émouvantes de Shakespeare comportent des scènes drôles et salaces. Ce livre-ci s'inscrit dans la même recherche d'authenticité que les pièces de Shakespeare, mais à la différence de Roméo et Juliette ou de La Tempête, ce n’est absolument pas une fiction. Il est très difficile à écrire parce que je n'édulcore rien, je ne déguise rien, et pour une musulmane c'est une démarche inédite, un effort à contre-courant. Les musulmanes sont censées choisir entre deux options opposées mais également insatisfaisantes : soit se taire comme des saintes-nitouches en plâtre, soit clamer haut et fort leur allégeance sans faille à République. Entre le destin de la potiche voilée et celui d'Henda Ayari, il n'y aurait rien à vivre. Je m'insurge contre cette dichotomie. Avec ou sans voile, une musulmane a le droit de dire tout ce qu'elle pense et de parler d'absolument tout ce dont elle veut parler, de la même manière qu'un homme lambda a ces droits-là. Elle a même le droit de parler de ses pulsions.

Our work is not to get rid of viruses, or we would, by definition, fail. Our work is to live alongside viruses and to protect as many human lives as we can. This depends, in part, on what viral stories we tell, what viral metaphors we use. A virus killed my friend. I miss her every day. I live alongside viruses every day, missing her. Her memory will make me smile; her memory will make me cry. It will make me angry, forever, at influenza, the virus that took her away, but that anger won’t get her, or us, a second chance. As individual humans and the collective we together form, death or symbiosis are our only options. The planet cannot continue to sustain our abuse. Will we eat it alive, use up its resources, and leave it an unsuitable host for further human reproduction? What will this earn us? Continued wealth for a small number of human animals is all. Human reproduction is not driving global warming; wealth production is. Human wealth will be lytic, killing our host planet and us with it. Lysogeny may still be an option. Symbiosis. We could understand, like one of lambda’s stories, that treating the host well is treating us well. The earth’s well-being is our own well-being. Lambda has its choice made for it by molecules and circumstances and luck. We have our molecules and circumstances, but we can make more than luck. We must choose it, actively and every day, a lysogenic viral story, a living with and caring for the earth because it means caring for ourselves. A virus is not an enemy; if it is, we will only lose. Viruses aren’t the problem, they’re a fact of the world. We are the problem when we refuse to protect one another’s lives as the most precious things we have. You are precious to me. We might well prefer a world without viruses, their everyday annoyances, the fever or runny nose, the cold sores, the never-ending possibility of pandemic. We won’t get a day without them. I miss Sarah every day. Viruses aren’t going anywhere. We get to choose what we become. For my part, I live to be lysogenic. Won’t you join me here?

There are too many of numbers for them to arise as a result of human intellectual activity. Consider, for example, the following series of functions: 2 lambda n is two to the second to the second .... to the second n times. The second member is ##2 (n); the third 3#2(n), etc.

lambda-cold-dark-matter”. This says that spacetime is flat, that about 5 per cent of the mass of the Universe is in the form of baryons (including bright stars and gas and dust), some 27 per cent is in the form of cold dark matter, and 68 per cent is in the form of the lambda field, also known as dark energy. This confirmation that the Universe is flat was the clinching evidence that some form of inflation is the key to understanding the origin of the Big Bang. But by the end of the 1990s, the inflationary scenario had gone through several stages of development, and related ideas were around even before Guth coined the name.    What is now recognised as the first inflationary model was developed by Alexei Starobinsky, at the L. D. Landau Institute of Theoretical Physics in Moscow, at the end of the 1970s — but it was not then called “inflation”. It was a very complicated model based on a quantum theory of gravity, but it caused a sensation among cosmologists in what was then the Soviet Union, becoming known as the “Starobinsky model” of the Universe. Unfortunately, because of the difficulties Soviet scientists still had in travelling abroad or

I HAVEN’T HAD the Dream in a long time. But it’s back. And it’s changed. It does not begin as it always has, with the chase. The woods. The mad swooping of the griffins and the charge of the hose-beaked vromaski. The volcano about to erupt. The woman calling my name. The rift that opens in the ground before me. The fall into the void. The fall, where it always ends. Not this time. This time, these things are behind me. This time, it begins at the bottom. I am outside my own body. I am in a nanosecond frozen in time. I feel no pain. I feel nothing. I see someone below, twisted and motionless. The person is Jack. Jack of the Dream. But being outside it, I see that the body is not mine. Not the same face. As if, in these Dreams, I have been dwelling inside a stranger. I see small woodland creatures, fallen and motionless, strewn around the body. The earth shakes. High above, griffins cackle. Water trickles beneath the body now. It pools around the head and hips. And the nanosecond ends. The scene changes. I am no longer outside the body but in. Deep in. The shock of reentry is white-hot. It paralyzes every molecule, short-circuiting my senses. Sight, touch, hearing—all of them join in one huge barbaric scream of STOP. The water fills my ear, trickles down my neck and chest. It freezes and pricks. It soothes and heals. It is taking hold of the pain, drawing it away. Drawing out death and bringing life. I breathe. My flattened body inflates. I see. Smell. Hear. I am aware of the soil ground into my skin, the carcasses all around, the black clouds lowering overhead. The thunder and shaking of the earth. I blink the grit from my eyes and struggle to rise. I have fallen into a crevice. The cracked earth is a vertical wall before me. And the wall contains a hole, a kind of door into the earth. I see dim light within. I stand on shaking legs. I feel the snap of shattered bones knitting themselves together. One step. Two. With each it becomes easier. Entering the hole, I hear music. The Song of the Heptakiklos. The sound that seems to play my soul like a guitar. I draw near the light. It is inside a vast, round room, an underground chamber. I enter, lifted on a column of air. At the other side I see someone hunched over. The white lambda in his hair flashes in the reflected torch fire. I call to him and he turns. He looks like me. Beside him is an enormous satchel, full to bursting. Behind him is the Heptakiklos. Seven round indentations in the earth. All empty.

Son regard faisait du bien, comme un plaid chaud posé sur le coeur.

A forEach operation that does anything more than present the result of the computation performed by a stream is a “bad smell in code,” as is a lambda that mutates state.

as this little function isn’t needed elsewhere, it was written inline as a lambda.

Python has a host of tools that most would consider functional in nature, which we enumerated in the preceding chapter — closures, generators, lambdas, comprehensions, maps, decorators, function objects, and more.

Because Lambda executes in a custom environment managed by AWS, it can be difficult to work through this cycle. Fortunately, a number of open source third-party libraries have sprung up to fill the need for testing. Ultimately, these tools mimic the “event” and “context” objects, along with their properties and method to simulate the environment in which Lambda functions launch once uploaded.

Two other guests made their appearance. The first was the Star King, who strode to the far end of the room in a flutter of rich garments: an individual with skin dyed jet-black, eyes like ebony cabochons as black as his skin. He was taller than average height, and carried himself with consummate arrogance. Lusterless as charcoal, the skin dye blurred the contrast of his features, made his face a protean mask. His garments were dramatically fanciful: breeches of orange silk, a loose scarlet robe with white sash, a loose striped gray and black coif which hung rakishly down the right side of his head. Gersen inspected him with open curiosity. This was the first Star King he had observed as such, though popular belief had hundreds moving incognito through the worlds of man: cosmic mysteries since the first human visit to Lambda Grus.

Amikor visszajöttem, az asztalon két sör állt, és az apám éppen a naptáramba irkált valamit. Bikst: lambda/3x (Gik Gst–Gis Gkt) – olvastam. – Hát ez meg mi? – kérdeztem. – Ez a Riemann–Christoffel-féle tenzor, a világegyetem mérésére szolgál – mondta. – És én mihez kezdjek vele? – Te? Semmit. Ihatsz még egy vodkát.

But deep down, she’s a developer. She’s a developer who loves functional programming because she knows that pure functions and composability are better tools to think with. She eschews imperative programming in favor of declarative modes of thinking. She despises and has a healthy fear of state mutation and non-referential transparency. She favors the lambda calculus over Turing machines because of their mathematical purity. She loves LISPs because she loves her code as data and vice versa.
