This book is divided into two parts. One part contains scien- tific contributions of research scientists from various areas of Phy- sics as well as personal accounts and life of Lattes. The other part includes reprints of some of the more important contributions of Cesar Lattes. Some of the contributions represent sincere testimony on the controversial personality of Cesar Lattes. They are memories of an era which are real testimonials of the vigour of a true scientist not only as a scientist but also as a generous and human personality. Lattes gave us his own testimony on his years at Bristol and his participation in the discovery of mesons in "My work in meson phy- sics with nuclear emulsions". On his participation in the search for artificially produced mesons, we reproduce a letter sent by Lattes to José Leite Lopes in 1948. On his years in Bristol, Prof. Beppo Occhialini, in his testi mony "The Bristol years", reveals us all the force and excitement of Lattes, then a young scientist, comparing him with the hero of univer- sal literature: Don Quixote. It is on the subtitle of his chronicle that Occhialini brought with extreme facility of the real personality of Lattes of yesterday and today as he saw him in science and life - "to see infinity in a grain of sand and eternity in an hour". Those of us who are working today with Lattes, 28 years after the "Cigarette Tower", can affirm that he has not changed a bit in re lation to his years at Bristol. Continuing to smoke horrible cigars, his presence still brings the stirring of sprintime, transmitting to the young the force of determination of seeing infinity in a grain of sand. His excitement and enthusiasm continues to affect "Sancho Panza". For younger physicists, Lattes is an attraction not for being Lattes but for his contagious atmosphere, his culture, his generosity and for his irreverence to the existing university structures. "The light of tower is available all nights even on Sundays because they have guidance". II Lattes belongs to a class of scientists in extinction. His in terests and intuition cover all fields of science. For Lattes,a scien- tist is made in the battle ground, da/ to day research but not in class rooms. Jose Bellandi Filho Anniraju Penmaraju Ill ACKNOWLEDGEMENTS The editors express their sincere thanks to Magnífico Reitor of the Universidade Estadual de Campinas, Prof. José Aristodemo Pinotti who put at our disposal all the human and material resources needed through the editor of Unicamp, Prof. Jaime Pinsky, to make possible the publication of the Festschrift volume. The editors also thank all scientists who sent in their origi- nal scientific contributions and participated in this festive occasion. Lastly, but for the support of the administrative personnel, in particular Miss Sandra Fonseca and Miss Marilena Aparecida Borelli who worked extensively on retyping the various contributed articles, this volume would not have been completed. To them, we owe our many thanks.

I risultati scientifici raggiunti da Cesar Lattes con la scoperta e produzione artificiale del mesone D sono tali da collocarlo al primo posto nella Fisica bra siliana, ai primissimi nel mondo, e da rendermi orgoglioso di poterlo dire mio al^ lievo.ila oltre al rispetto e alla stima per il talento dello studioso, mi lega a Cesar Lattes una profonda amicizia, le cui basi sono state poste negli anni in cui il giovane Lattes affrontava pieno di entusiasmo le sue prime prove di scien- ziato e che si è poi sviluppata nel corso di una feconda collaborazione nello studio dei raggi cosmici ed in particolare della radiazione penetrante. Questa and cizia non si è interrotta dopo il mio ritorno in Italia ed è stata per me una gioia ravvivarla quando, proprio su iniziativa di Lattes, ho ritrovato, ormai in pensione dall'Università italiana, la strada del Brasile e, se cosi posso dire, un u rol un gamento di giovinezza alla Università di Campinas, ¡ii ò dunque particolarmente gradito associarmi a questa celebrazione, con i più calorosi rallegramenti all'amico Lattes ed i più fervidi auguri per lunghi e fecondi anni di lavoro scientifico.

Je l'ai renccntré souvent, soit à Bristol, avec Occhiaiini et C. Powell, et bien souvent aussi en France et ailleurs. C'était un jeune physiciexn plein de charme, aux yeux pétillant» d'intelligence, avec une très grande ouverture d'esprit. Nos conver- sations étaient toujours vivantes, animées, et nous pouvions aborder tous les sujets, parfois sérieusement, souvent de façon plus détendue. J'ai toujours été sensible a l'humour, et Lattes en possédait beau- coup. Son esprit chercheur, inventif était imprégné d'une grande fan- taisie, ce qui me plaisait particulièrement. Depuis plusieurs décennies, je n'ai pas eu la chance de le revoir longuement et je le regrette. J'étais de loin son aîné, puisque j'ai toujours vingt-trois ans de plus que lui.

TSA released a statement on the decision at the request of the US-Cuba Trade and Economic Council. TSA explained that In-Flight Security Officers (IFSOs), also known as federal air marshals, play a crucial role in aviation security. The agency plans to continue to work with Cuba to expand the presence of IFSOs on flights to and from Cuba. “This agreement will strengthen both parties' aviation security efforts by furnishing a security presence on board certain passenger flights between the United States and The Republic of Cuba,” TSA said in the statement, adding, “IFSOs serve as an active last line of defense against terrorism and air piracy, and are an important part of a multi- layer strategy adopted by the US to thwart terrorism in the civil aviation sector.” Commenting on the announcement, Rep. Michael McCaul (R-Texas), Chairman of the House Committee on Homeland Security, warned that despite the presence of federal air marshals on flights between the two countries, Americans traveling to Cuba remain at risk.

  • Electron-Positron Pairs in Physics and Astrophysics
    Electron-positron pairs in physics and astrophysics: from heavy nuclei to black holes Remo Ruffini1,2,3, Gregory Vereshchagin1 and She-Sheng Xue1 1 ICRANet and ICRA, p.le della Repubblica 10, 65100 Pescara, Italy, 2 Dip. di Fisica, Universit`adi Roma “La Sapienza”, Piazzale Aldo Moro 5, I-00185 Roma, Italy, 3 ICRANet, Universit´ede Nice Sophia Antipolis, Grand Chˆateau, BP 2135, 28, avenue de Valrose, 06103 NICE CEDEX 2, France. Abstract Due to the interaction of physics and astrophysics we are witnessing in these years a splendid synthesis of theoretical, experimental and observational results originating from three fundamental physical processes. They were originally proposed by Dirac, by Breit and Wheeler and by Sauter, Heisenberg, Euler and Schwinger. For almost seventy years they have all three been followed by a continued effort of experimental verification on Earth-based experiments. The Dirac process, e+e 2γ, has been by − → far the most successful. It has obtained extremely accurate experimental verification and has led as well to an enormous number of new physics in possibly one of the most fruitful experimental avenues by introduction of storage rings in Frascati and followed by the largest accelerators worldwide: DESY, SLAC etc. The Breit–Wheeler process, 2γ e+e , although conceptually simple, being the inverse process of the Dirac one, → − has been by far one of the most difficult to be verified experimentally. Only recently, through the technology based on free electron X-ray laser and its numerous applications in Earth-based experiments, some first indications of its possible verification have been reached. The vacuum polarization process in strong electromagnetic field, pioneered by Sauter, Heisenberg, Euler and Schwinger, introduced the concept of critical electric 2 3 field Ec = mec /(e ).

SALMERON COM GRANDE honra e imenso prazer que tenho a oportunidade de falar a respeito de Gleb Wataghin, o homem que ensinou aos brasileiros os funda- É mentos da física moderna, como aprender esses fundamentos e como fa- zer pesquisa em física. A história de Gleb Wataghin no Brasil é uma história de grande beleza e fora do comum. Não há muitos exemplos semelhantes de cientis- tas que, por suas ações pessoais, tiveram tão grande influência sobre tantas pessoas de gerações diferentes num país, que nem era o seu próprio país. Os alunos de Gleb Wataghin, e os alunos de seus alunos, espalharam-se por diferentes lugares, con- tribuindo para fazer da física brasileira o que ela é hoje. A descrição do trabalho de Gleb Wataghin no Brasil necessitaria muito mais do que uma simples palestra. Poderemos, entretanto, apresentar um pequeno resumo no qual tentaremos pôr em evidência alguns dos aspectos da sua persona- lidade como homem, como físico e como mestre. A fundação da Universidade de São Paulo Gleb Wataghin nasceu na Rússia, mas viveu na Itália, para onde sua família emigrou. Estudou naquele país e, em 1934, veio de Turim para São Paulo. Para compreender a influência que exerceu, e poder avaliar a sua extensão, é necessário conhecer algo a respeito das escolas superiores no Brasil naquele período. Havia no país uma só universidade, fundada em 1920 no Rio de Janeiro. Esta universi- dade era formada pelas escolas superiores já existentes antes da sua fundação: Engenharia, Medicina, Direito e Odontologia, colocadas então sob uma única administração, mas sem qualquer conexão – intelectual ou profissional – entre elas.

ICRANet seat in Nice (France). National Academy of Sciences of Armenia, which hosts the ICRANet seat in Yerevan (Armenia). (Above:) CBPF, which hosts the ICRANet seat in Rio de Janeiro. (Below:) The planned seat at Cassino da Urca (Brazil). II This brochure reviews some background facts concerning the founding of ICRANet and its current structures and then turns to the 2015 celebrations of the Year of Light and the ICRANet initiated International Relativistic Astrophysics Ph.D. program (the IRAP-PhD). It then addresses the birth of relativistic astrophysics following the first fifty years of the existence of general relativity plagued mainly by the absence of observational or experimental activity. Four events marked the onset of relativistic astrophysics: the discovery by Schmidt of the first quasar in 1962, of Scorpius X1 by Riccardo Giacconi in 1963, of the cosmic background radiation by Penzias and Wilson in 1964, and of pulsars by Jocelyn-Bell and Antony Hewish in 1967. These events led to a systematic development of the understanding of the four pillars of relativistic astrophysics: supernovae where observations of the CRAB Nebula are still relevant today, white dwarfs and neutron stars, black holes and their first identification in Nature in Cygnus X1 found by Riccardo Giacconi with the UHURU satellite based on the conceptual background developed by our group in Princeton, and finally the discovery of gamma ray bursts as the largest energy source delivered in the shortest time of any astrophysical phenomenon.

  • Entrevista Roberto Salmeron “ENSINO PAGO NAS UNIVERSIDADES PÚBLICAS SERIA UM CRIME” Por Lighia B
    OS CIENTISTAS ERGUEM A VOZ Uma coincidência reuniu, nas páginas da Revista Adusp, dois dos maiores físicos brasileiros. Roberto Salmeron, que vive na França há muitos anos, veio ao Brasil para lançar seu livro sobre a UnB, e passou pela USP, de modo que não perdemos a oportunidade de entrevistá-lo. José Leite Lopes, por sua vez, re- cebera o Prêmio Unesco de Ciências 1999 quando a edição anterior da revista já estava fechada. Indis- pensável, assim, buscar seu depoimento. Ambos reivindicam para a educação e a ciência a grandeza que o neoliberalismo dominante tem negado a uma e outra. Ambos conferem à universidade pública (e à pesquisa a ela vinculada) papel central na produção do conhecimento. Ambos saem em defesa da ciência brasileira, acuada pelo colapso dos programas de financiamento da pesquisa, intimidada pelos ataques à autonomia universitária, ameaçada pelo desmonte do sistema público de ensino em todos os níveis. Ainda que em tom mais contido, a SBPC também reage ao desmantelamento do saber nacional, partindo para a “cartografia” da C&T nas diferentes regiões do país, em inédita maratona que entu- siasma Glaci Zancan, nova presidente da entidade. Por fim, este bloco de matérias é enriquecido por artigo de Romualdo Portela e Sandra Zákia sobre critérios e métodos de avaliação da produção dos docentes universitários, tema muito pertinente quando se sabe que a elaboração de rankings da ciên- cia pode resultar desastrosa. ✦✦✦ Acumulam-se os sintomas de uma crise generalizada do capitalismo. Tensões, conflitos, uma reto- mada sob novas vestes de práticas e discursos (como o darwinismo social) que pareciam sepultados ao final da Segunda Guerra Mundial.
