Esperienza inSegna 2015 | PALERMOSCIENZA Dall'intervista immaginaria a Newton al "libro pazzo" sul Sole e le ombre Da sabato 21 a Palermo sette giorni su "Luce, energia e cibo" Al via "Esperienza inSegna", la più grande manifestazione scientifica del Sud Eventi, exhibit e spettacoli al Polididattico dell'Ateneo per una settimana Quanta energia consuma il nostro corpo e quanto cibo è realmente necessario? Forte del successo delle edizioni precedenti, con oltre diecimila visitatori per anno, da sabato 21 fino al 28 febbraio, il Polididattico dell'Università di Palermo diventerà un laboratorio aperto a chiunque voglia scoprire i segreti dei tre elementi alla base del ciclo vitale. La manifestazione si aprirà alle 10 con una tavola rotonda presieduta dal rettore Roberto Lagalla. Quarantatré scuole siciliane di ogni ordine e grado, l'Università, il CNR, numerosi enti di ricerca e associazioni, dopo aver lavorato fianco a fianco per mesi interi, si confronteranno durante le varie sessioni e attività.
Proof That White Dwarfs Can Reignite and Explode as Supernovae This sequence shows some of the steps leading up to and following the explosion. A white dwarf, a star that contain up to 1.4 times the mass of the Sun squeezed into a volume about the same size as the Earth, leeches matter from a companion star (image 1). The Integral measurements suggest that a belt of gas from the companion star builds up around the equator of the white dwarf (image 2). This belt detonates (image 3) and triggers the internal explosion that becomes the supernova (image 4). Material from the explosion expands (image 5) and eventually becomes transparent to gamma rays (image 6). New research shows without a doubt that white dwarf stars can reignite and explode as supernovae. Astronomers using ESA’s Integral gamma-ray observatory have demonstrated beyond doubt that dead stars known as white dwarfs can reignite and explode as supernovae. With that confirmation in hand, other astronomers could begin to look into the details of the process. Publications: E.
Explorations in Science :: Official Website of Dr. Michio Kaku Coral Castle Museum Supreme Council of Antiquities - Museums The Egyptian Museum in Cairo contains the world's most extensive collection of pharaonic antiquities; no visit to Egypt is complete without a trip through its galleries. The original collection was established in the late 19th century under Auguste Mariette and housed in Boulaq. The objects were moved in 1891 to the palace of Ismail Pasha in Giza before being transferred in 1902 to the current building at Tahrir Square, which is the first purpose-built museum edifice in the world. Designed in the Neoclassical style by Marcel Dourgnon, the Egyptian Museum boasts 107 halls filled with artifacts dating from the prehistoric through the Roman periods, with the majority of the collection focused on the pharaonic era. Labels are in Arabic and English HOURS OF OPERATION: Open daily, 9:00 AM-7:00 PM 9:00 AM-5:00 PM during Ramadan LOCATION: Midan al-Tahrir, Downtown Cairo DIRECTIONS: By metro: Sadat Station, follow signs to Egyptian Museum exit and walk straight along the street.
ANIEF - Homepage Readings - Bohmian-Mechanics.net This is part of a correspondence between Sheldon Goldstein and Steven Weinberg on Bohmian Mechanics. It is published here with the kind permission of both. From: oldstein@fermat.rutgers.edu To: WEINBERG@utaphy.ph.utexas.edu Subject: NYRB Date: Sun, Sep 22 1996, 17:14:44 Dear Professor Weinberg, In your recent response in the NYRB, you ask George Levine, my colleague here at Rutgers, to "suppose that physicists were to announce the discovery that, beneath the apparently quantum mechanical appearance of atoms, there lies a more fundamental substructure of fields and particles that behave according to the rules of plain old classical mechanics." I agree with your point that this should make little difference to our views about culture or philosophy. Best, Shelly Goldstein From: WEINBERG@physics.utexas.edu To: oldstein@fermat.rutgers.edu Subject: Bohm's quantum mechanics Date: Tue, 24 Sep 1996, 21:01:39 -0500 (CDT) Dear Professor Oldstein, I have carried out the experiment you requested.
