Beyond 'absolute zero' temperatures get hotter It sounds like a contradiction in terms but scientists have reached temperatures that go beyond absolute zero in a lab, and get hotter as they do so. Whereas we’re all aware of what happens when temperatures hit negative temperatures on the Fahrenheit and Celsius scales (hint: it gets really cold), the Kelvin scale is an absolute temperature scale in physics where it is not possible to go beyond 0 degrees Kelvin. Therefore, the lowest point that any temperature can reach is 0 K or −460 °F (−273.15 °C); at least that’s what scientists thought until till now. When they cooled an atomic gas to extreme lows, known as ‘ultracooling’, physicists at the Ludwig-Maximilians University Munich and the Max Planck Institute of Quantum Optics in Germany created a gas that went beyond absolute zero. They found that the atoms in the ultracooled gas attract each other and give rise to a negative pressure. Instead of standing still when they go beyond 0 K, the gas becomes hotter.
24 Terrifying, Thoughtful and Absurd Nursery Rhymes for Children In more repressed times, people were not always allowed to express themselves freely, for fear of persecution. Gossiping, criticizing the government or even talking about current events were often punishable by death. In order to communicate at will, clever rhymes were constructed and passed around to parody public figures and events. The first nursery rhymes can be traced back to the fourteenth century. While the Bubonic Plaque ravaged England, peasants used a rhyme to spread the word about equality. The "Adam and Eve" rhyme made peasants realize that they were important to the economy and contributed to the Peasants Revolt of 1381. Other nursery rhymes don't seem to carry a particular message at all, but convey a macabre sense of humor. Humpty Dumpty Humpty Dumpty sat on a wall,Humpty Dumpty had a great fall,All the King's Horses and all the King's menCouldn't put Humpty together again. In children's books, Humpty Dumpty is portrayed as a large egg, usually dressed like a little boy.

Souto de Moura e il disegno “Bic/Bic/Bic – Bic Cristal – Nessuno disegna tanto per disegnare. Disegnare non è un hobby, disegnare, in Architettura, significa dover risolvere un problema. Gli architetti disegnano per dovere, non per piacere; come nella Scuola di Belle Arti, dove c’era un orario, un modello, un professore, e noi alunni chiusi tra i cavalletti. Disegnare, in Architettura, è correre contro il tempo, prendere ciò che sta a portata di mano: una scatola di fiammiferi, un biglietto del tram, un pacchetto di sigarette rovesciato, i sacchetti per il mal d’aria che si trovano in aereo, oppure il nostro quaderno, che non deve avere carta di pregio. La carta, se è di buona qualità, spessa, ci intimidisce, facciamo cerimonie, ci inibisce i gesti, e non è per la grammatura della carta che passiamo ai posteri. Anche la penna deve essere banale, leggera, anonima e disponibile in ogni angolo della città.
Is dark energy static or dynamic? (Phys.org)—While hypothesized dark energy can explain observations of the universe expanding at an accelerating rate, the specific properties of dark energy are still an enigma. Scientists think that dark energy could take one of two forms: a static cosmological constant that is homogenous over time and space, or a dynamical entity whose energy density changes in time and space. By examining data from a variety of experiments, scientists in a new study have developed a model that provides tantalizing hints that dark energy may be dynamic. The scientists, Gong-Bo Zhao of the University of Portsmouth in the UK and the Chinese Academy of Science in Beijing; Robert G. Crittenden of the University of Portsmouth; Levon Pogosian of Simon Fraser University in Burnaby, British Columbia, and the University of Portsmouth; and Xinmin Zhang of the Chinese Academy of Science, have published their paper on the evidence for dynamical dark energy in a recent issue of Physical Review Letters.
Alice's Adventures in Wonderland Background[edit] Page from the original manuscript copy of Alice's Adventures Under Ground, 1864 Alice was published in 1865, three years after the Reverend Charles Lutwidge Dodgson and the Reverend Robinson Duckworth rowed in a boat, on 4 July 1862[4] (this popular date of the "golden afternoon"[5] might be a confusion or even another Alice-tale, for that particular day was cool, cloudy and rainy[6]), up the Isis with the three young daughters of Henry Liddell (the Vice-Chancellor of Oxford University and Dean of Christ Church): Lorina Charlotte Liddell (aged 13, born 1849) ("Prima" in the book's prefatory verse); Alice Pleasance Liddell (aged 10, born 1852) ("Secunda" in the prefatory verse); Edith Mary Liddell (aged 8, born 1853) ("Tertia" in the prefatory verse).[7] The journey began at Folly Bridge near Oxford and ended five miles away in the village of Godstow.

Starting With Nothing and Ending Up With Everything by Bruce Rawles Question: What's black and white and blinks in and out of existence 1044 (a lot) times per second? And is in every 1/1033 cubic centimeter of space (every teeny tiny bit)? Answer: Hey ... Everything! —W. Okay, it's time to dig down into the mental archives of your high school geometry class. If your geometry teacher was typical, the subject of the infinitesimal point was probably glossed over quickly to usher you into more "important" theorems and pragmatic applications. But let's hit the virtual PAUSE button on the subject of the point for a while, and give it the attention it deserves. The Infinitesimal Point A pure, ideal, mathematically pristine and glittering point occupies no space. Wait just a picosecond. If so, or even if you did boggle on it a while, let's explore the dimensionless point a bit further ... so you'll get my point ... about the point. Now that could come in handy. I've also found, to the delight of Ram Dass fans worldwide, that "here" appears to be quite portable.
Sephirot Sephirot (/sfɪˈroʊt/, /ˈsfɪroʊt/; Hebrew: סְפִירוֹת Səphîrôṯ), meaning emanations, are the 10 attributes/emanations in Kabbalah, through which Ein Sof (The Infinite) reveals himself and continuously creates both the physical realm and the chain of higher metaphysical realms (Seder hishtalshelus). The term is alternatively transliterated into English as Sefirot/Sefiroth, singular Sephirah/Sefirah etc. Alternative configurations of the sephirot are given by different schools in the historical development of Kabbalah, with each articulating different spiritual aspects. The tradition of enumerating 10 is stated in the Sefer Yetzirah, "Ten sephirot of nothingness, ten and not nine, ten and not eleven". In Hasidic philosophy, which has sought to internalise the experience of Jewish mysticism into daily inspiration (dveikus), this inner life of the sephirot is explored, and the role they play in man's service of God in this world.

New phase of water could dominate the interiors of Uranus and Neptune (Phys.org) —While everyone is familiar with water in the liquid, ice, and gas phases, water can also exist in many other phases over a vast range of temperature and pressure conditions. One lesser known phase of water is the superionic phase, which is considered an "ice" but exists somewhere between a solid and a liquid: while the oxygen atoms occupy fixed lattice positions as in a solid, the hydrogen atoms migrate through the lattice as in a fluid. Until now, scientists have thought that there was only one phase of superionic ice, but scientists in a new study have discovered a second phase that is more stable than the original. The new phase of superionic ice could make up a large component of the interiors of giant icy planets such as Uranus and Neptune. The scientists, Hugh F. Exotic water As the scientists explain, water has an unusually rich phase diagram, with 15 crystalline phases observed in laboratory experiments and eight additional phases predicted theoretically.

Scrivere Architettura. Instabilità del “genere” e trivellazione della “forma” | alienlog Antonello Da Messina. San Gerolamo nello studio. 1474 – 1475 Intervento proposto nel corso del convegno “Presente Teorico condizioni e possibilità per una teoria dell’architettura” Una premessaIo penso che l’architetto debba includere nel proprio patrimonio di conoscenze, oltre agli aspetti tecnico-deontologici e scientifici, un vettore “critico” in grado di porlo in modo non incerto al centro delle questioni fondamentali della disciplina, alfine di acquisire una complessiva consapevolezza dell’importanza politica e culturale che ricopre nella società. Io penso infatti che l’abiura, il sofferto disincanto, lo scetticismo rassegnato che ha contraddistinto il modo di guardare all’architettura e all’identità professionale ed intellettuale dell’architetto negli ultimi anni, derivi dall’aver estromesso volontariamente l’istanza culturale, teorico-critica, dalla nostra ottica complessiva.
