“Having discovered the existence of a new kind of rays, I of course began to investigate what they would do. … It soon appeared from tests that the rays had penetrative power to a degree hitherto unknown.”

Wilhelm Röntgen (1845–1923) German physicist

The New Marvel in Photography (1896)
Context: Having discovered the existence of a new kind of rays, I of course began to investigate what they would do. … It soon appeared from tests that the rays had penetrative power to a degree hitherto unknown. They penetrated paper, wood, and cloth with ease; and the thickness of the substance made no perceptible difference, within reasonable limits. … The rays passed through all the metals tested, with a facility varying, roughly speaking, with the density of the metal. These phenomena I have discussed carefully in my report to the Würzburg society, and you will find all the technical results therein stated.

“Placing your stick at the end of the shadow of the pyramid, you made by the sun's rays two triangles, and so proved that the pyramid [height] was to the stick [height] as the shadow of the pyramid to the shadow of the stick.”

“For as children tremble and fear everything in the blind darkness, so we in the light sometimes fear what is no more to be feared than the things that children in the dark hold in terror and imagine will come true. This terror, therefore, and darkness of mind must be dispelled not by the rays of the sun and glittering shafts of daylight, but by the aspect and law of nature.”
Nam veluti pueri trepidant atque omnia caecis in tenebris metuunt, sic nos in luce timemus interdum, nilo quae sunt metuenda magis quam quae pueri in tenebris pavitant finguntque futura. hunc igitur terrorem animi tenebrasque necessest non radii solis neque lucida tela diei discutiant sed naturae species ratioque.

“The light came through the window,
Straight from the sun above,
And so inside my little room
There plunged the rays of Love.”

Context: p>The light came through the window,
Straight from the sun above,
And so inside my little room
There plunged the rays of Love.In streams of light I clearly saw
The dust you seldom see,
Out of which the Nameless makes
A Name for one like me.</p

“For mum we're fly. What mum you don't know who am I? I am Józio. And this is my sister Rózia. Now we're fly in sky! There is better than mum. See how heads in ray. Clothes with lucifer light. And on my hand as butterfly airfoil in sky we have all what we want, every day other toy, where we go here is grass, where we touch here is a flower. But we have what we want, torture us boring and trepidation. Oh mum for Your children road to heaven has been closed! On Always!”

Do mamy lecim do mamy! Cóż to, mamo nie znasz Józia? Ja to Józio ja ten samy. A to moja siostra Rózia. My teraz w raju latamy, Tam nam lepiej niż u mamy. Patrz jakie główki w promieniu, Ubiór z jutrzenki światełka, A na oboim ramieniu Jak u motylków skrzydełka, w raju wszystkiego dostatek, Co dzień to inna zabawka, gdzie stąpim wypływa trawka, gdzie dotkniem rozkwita kwiatek. Lecz choć wszystkiego dostatek dręczy nad nuda i trwoga. Ach mamo dla twoich dziatek zamknięta do nieba droga!

“We see from Lenard's table that a cathode ray can travel through air at atmospheric pressure a distance of about half a centimetre before the brightness of the phosphorescence falls to about half its original value. Now the mean free path of the molecules of air at this pressure is about 10-5 cm., and if a molecule of air were projected it would lose half its momentum in a space comparable with the mean free path. Even if we suppose that it is not the same molecule that is carried, the effect of the obliquity of the collisions would reduce the momentum to half in a short multiple of that path. Thus, from Lenard's experiments on the absorption of the rays outside the tube, it follows on the hypothesis that the cathode rays are charged particles moving with high velocities, that the size of the carriers must be small compared with the dimensions of ordinary atoms or molecules. The assumption of a state of matter more finely subdivided than the atom of an element is a somewhat startling one; but a hypothesis that would involve somewhat similar consequences—viz. that the so-called elements are compounds of some primordial element—has been put forward from time to time by various chemists.”

J. J. Thomson (1856–1940) British physicist

“And in that moment we all thought of the space that her round arms would occupy moving backward and forward with the rolling pin over the dough, her bosom leaning over the great mound of flour and eggs, […] and we thought of the space the flour would occupy, and the wheat for the flour, and the fields to raise the wheat, and the mountains from which the water would flow to irrigate the fields; […] of the space it would take for the Sun to arrive with its rays, to ripen the wheat; of the space for the Sun to condense from the clouds of stellar gases and burn; of the quantities of stars and galaxies and galactic masses in flight through space which would be needed to hold suspended every galaxy, every nebula, every sun, every planet, and at the same time we thought of it, this space was inevitably being formed, at the same time that Mrs. Ph(i)Nk0 was uttering those words: "… ah, what noodles, boys!" the point that contained her and all of us was expanding in a halo of distance in light-years and light-centuries and billions of light-millennia, and we were being hurled to the four corners of the universe, […] and she, dissolved into I don't know what kind of energy-light-heat, she, Mrs. Ph(i)Nk0, she who in the midst of our closed, petty world had been capable of a generous impulse, "Boys, the noodles I would make for you!," a true outburst of general love, initiating at the same moment the concept of space and, properly speaking, space itself, and time, and universal gravitation, and the gravitating universe, making possible billions and billions of suns, and of planets, and fields of wheat, and Mrs. Ph(i)Nk0s, scattered through the continents of the planets, kneading with floury, oil-shiny, generous arms, and she lost at that very moment, and we, mourning her loss.”

“Nature may reach the same result in many ways. Like a wave in the physical world, in the infinite ocean of the medium which pervades all, so in the world of organisms, in life, an impulse started proceeds onward, at times, may be, with the speed of light, at times, again, so slowly that for ages and ages it seems to stay, passing through processes of a complexity inconceivable to men, but in all its forms, in all its stages, its energy ever and ever integrally present. A single ray of light from a distant star falling upon the eye of a tyrant in bygone times may have altered the course of his life, may have changed the destiny of nations, may have transformed the surface of the globe, so intricate, so inconceivably complex are the processes in Nature. In no way can we get such an overwhelming idea of the grandeur of Nature than when we consider, that in accordance with the law of the conservation of energy, throughout the Infinite, the forces are in a perfect balance, and hence the energy of a single thought may determine the motion of a universe.”

Nikola Tesla (1856–1943) Serbian American inventor

“I shall not attempt to paint to you the feelings of this heart, nor the majestic beauty and glory which surrounded us on this occasion; but you will believe me when I say, that earth, nor men, with the eloquence of time, cannot begin to clothe language in as interesting and sublime a manner as this holy personage. No; nor has this earth power to give the joy, to bestow the peace, or comprehend the wisdom which was contained in each sentence as they were delivered by the power of the Holy Spirit! Man may deceive his fellow-men, deception may follow deception, and the children of the wicked one may have power to seduce the foolish and untaught, till naught but fiction feeds the many, and the fruit of falsehood carries in its current the giddy to the grave; but one touch with the finger of his love, yes, one ray of glory from the upper world, or one word from the mouth of the Savior, from the bosom of eternity, strikes it all into insignificance, and blots it forever from the mind. The assurance that we were in the presence of an angel, the certainty that we heard the voice of Jesus, and the truth unsullied as it flowed from a pure personage, dictated by the will of God, is to me past description, and I shall ever look upon this expression of the Savior’s goodness with wonder and thanksgiving while I am permitted to tarry; and in those mansions where perfection dwells and sin never comes, I hope to adore in that day which shall never cease.”

“This is our mission: to cast a ray of light and pass on.”

Maria Montessori (1870–1952) Italian pedagogue, philosopher and physician

Source: The Discovery of the Child (1948), Ch. 8 : The Exercises, p. 141
Variant translation:
This then is the first duty of an educator: to stir up life but leave it free to develop.
Context: This is our mission: to cast a ray of light and pass on. I compare the effects of these first lessons the impressions of a solitary wanderer who is walking serene and happy in a shady grove, meditating; that is leaving his inner thought free to wander. Suddenly a church bell pealing out nearby recalls to himself; then he feels more keenly that peaceful bliss which had already been born, though dormant, within him.
To stimulate life, leaving it free, however, to unfold itself, that is the first duty of the educator.
For such a delicate mission great art is required to suggest the right moment and to limit intervention, last one should disturb or lead astray rather than help the soul which is coming to life and which will live by virtue of it's own efforts.
This art must accompany the scientific method, because the simplicity of our lessons bears a great resemblance to experiments in experimental psychology.

“Men have gone towards each other because of that ray of light which each of them contains; and light resembles light.”

Henri Barbusse (1873–1935) French novelist

Light (1919), Ch. XVI - De Profundis Clamavi
Context: Men have gone towards each other because of that ray of light which each of them contains; and light resembles light. It reveals that the isolated man, too free in the open expanses, is doomed to adversity as if he were a captive, in spite of appearances; and that men must come together that they may be stronger, that they may be more peaceful, and even that they may be able to live.
For men are made to live their life in its depth, and also in all its length. Stronger than the elements and keener than all terrors are the hunger to last long, the passion to possess one's days to the very end and to make the best of them. It is not only a right; it is a virtue.

“In a few minutes there was no doubt about it. Rays were coming from the tube which had a luminescent effect upon the paper.”

Wilhelm Röntgen (1845–1923) German physicist

The New Marvel in Photography (1896)
Context: I was working with a Crookes tube covered by a shield of black cardboard. A piece of barium platino-cyanide paper lay on the bench there. I had been passing a current through the tube, and I noticed a peculiar black line across the paper. … The effect was one which could only be produced, in ordinary parlance, by the passage of light. No light could come from the tube, because the shield which covered it was impervious to any light known, even that of the electric arc. … I did not think; I investigated. I assumed that the effect must have come from the tube, since its character indicated that it could come from nowhere else. I tested it. In a few minutes there was no doubt about it. Rays were coming from the tube which had a luminescent effect upon the paper. I tried it successfully at greater and greater distances, even at two metres. It seemed at first a new kind of invisible light. It was clearly something new, something unrecorded.

“Shadow is not the absence of light, merely the obstruction of the luminous rays by an opaque body.”

Leonardo Da Vinci (1452–1519) Italian Renaissance polymath

The Notebooks of Leonardo da Vinci (1883), III Six books on Light and Shade
Context: Shadow is not the absence of light, merely the obstruction of the luminous rays by an opaque body. Shadow is of the nature of darkness. Light is of the nature of a luminous body; one conceals and the other reveals. They are always associated and inseparable from all objects. But shadow is a more powerful agent than light, for it can impede and entirely deprive bodies of their light, while light can never entirely expel shadow from a body, that is from an opaque body.

“By art alone we are able to get outside ourselves, to know what another sees of this universe which for him is not ours, the landscapes of which would remain as unknown to us as those of the moon. Thanks to art, instead of seeing one world, our own, we see it multiplied and as many original artists as there are, so many worlds are at our disposal, differing more widely from each other than those which roll round the infinite and which, whether their name be Rembrandt or Vermeer, send us their unique rays many centuries after the hearth from which they emanate is extinguished.This labour of the artist to discover a means of apprehending beneath matter and experience, beneath words, something different from their appearance, is of an exactly contrary nature to the operation in which pride, passion, intelligence and habit are constantly engaged within us when we spend our lives without self-communion, accumulating as though to hide our true impressions, the terminology for practical ends which we falsely call life.”

Par l’art seulement, nous pouvons sortir de nous, savoir ce que voit un autre de cet univers qui n’est pas le même que le nôtre et dont les paysages nous seraient restés aussi inconnus que ceux qu’il peut y avoir dans la lune. Grâce à l’art, au lieu de voir un seul monde, le nôtre, nous le voyons se multiplier, et autant qu’il y a d’artistes originaux, autant nous avons de mondes à notre disposition, plus différents les uns des autres que ceux qui roulent dans l’infini et qui, bien des siècles après qu’est éteint le foyer dont il émanait, qu’il s’appelât Rembrandt ou Vermeer, nous envoient encore leur rayon spécial.<p>Ce travail de l’artiste, de chercher à apercevoir sous la matière, sous de l’expérience, sous des mots, quelque chose de différent, c’est exactement le travail inverse de celui que, à chaque minute, quand nous vivons détourné de nous-même, l’amour-propre, la passion, l’intelligence, et l’habitude aussi accomplissent en nous, quand elles amassent au-dessus de nos impressions vraies, pour nous les cacher entièrement, les nomenclatures, les buts pratiques que nous appelons faussement la vie.

“But in the judgments they exercise they are most accurate and just, nor do they pass sentence by the votes of a court that is fewer than a hundred. And as to what is once determined by that number, it is unalterable. What they most of all honor, after God himself, is the name of their legislator [Moses], whom if any one blaspheme he is punished capitally. They also think it a good thing to obey their elders, and the major part. Accordingly, if ten of them be sitting together, no one of them will speak while the other nine are against it. They also avoid spitting in the midst of them, or on the right side. Moreover, they are stricter than any other of the Jews in resting from their labors on the seventh day; for they not only get their food ready the day before, that they may not be obliged to kindle a fire on that day, but they will not remove any vessel out of its place, nor go to stool thereon. Nay, on other days they dig a small pit, a foot deep, with a paddle (which kind of hatchet is given them when they are first admitted among them); and covering themselves round with their garment, that they may not affront the Divine rays of light, they ease themselves into that pit, after which they put the earth that was dug out again into the pit; and even this they do only in the more lonely places, which they choose out for this purpose; and although this easement of the body be natural, yet it is a rule with them to wash themselves after it, as if it were a defilement to them.”

Firuz Shah Tughlaq photo

“Forcible marriages, euphemistically called matrimonial alliances, were common throughout the medieval period. Only some of them find mention in Muslim chronicles with their bitter details. Here is one example given by Shams Siraj Afif (fourteenth century). The translation from the original in Persian may be summarised as follows. Firoz Shah was born in the year 709 H. (1309 C. E.). His father was named Sipahsalar Rajjab, who was a brother of Sultan Ghiyasuddin Tughlaq Ghazi. The three brothers, Tughlaq, Rajjab, and Abu Bakr, came from Khurasan to Delhi in the reign of Alauddin (Khalji), and that monarch took all the three in the service of the Court. The Sultan conferred upon Tughlaq the country of Dipalpur. Tughlaq was desirous that his brother Sipahsalar Rajjab should obtain in marriage the daughter of one of the Rais of Dipalpur. He was informed that the daughters of Ranamall Bhatti were very beautiful and accomplished. Tughlaq sent to Ranamall a proposal of marriage. Ranamall refused. Upon this Tughlaq proceeded to the villages (talwandi) belonging to Ranamall and demanded payment of the whole year’s revenue in a lump sum. The Muqaddams and Chaudharis were subjected to coercion. Ranamall’s people were helpless and could do nothing, for those were the days of Alauddin, and no one dared to make an outcry. One damsel was brought to Dipalpur. Before her marriage she was called Bibi Naila. On entering the house of Sipahsalar Rajjab she was styled Sultan Bibi Kadbanu. After the lapse of a few years she gave birth to Firoz shah. If this could be accomplished by force by a regional officer, there was nothing to stop the king.”
