We apply an online optimization process based on machine learning to the production of Bose-Einstein condensates. BEC is typically created with an exponential evaporation ramp that is optimal for ergodic dynamics with two-body s-wave interactions and no other loss rates, but likely sub-optimal for real experiments. Through repeated machine-controlled scientific experimentation and observations our ’learner’ discovers an optimal evaporation ramp for BEC production. In contrast to previous work, our learner uses a Gaussian process to develop a statistical model of the (...) relationship between the parameters it controls and the quality of the BEC produced. We demonstrate that the Gaussian process machine learner is able to discover a ramp that produces high quality BECs in 10 times fewer iterations than a previously used online optimization technique. Furthermore, we show the internal model developed can be used to determine which parameters are essential in BEC creation and which are unimportant, providing insight into the optimization process of the system.

Some people have supposed that utility is good in itself, non-in-strumentally good, as distinct from good because conducive to other good things. And in modern versions of this view, utility often means want-satisfaction, as distinct from pleasure or happiness. For your want that p to be satisfied, is it necessary that you know or believe that p, or sufficient merely that p is true? However that question is answered, there are problems with the view that want-satisfaction is a non-instrumental good. (...) What if you want something only because you have a false belief? What if the time at which you want that p is fifty or five hundred years before the time to which p itself refers? To meet these difficulties, qualifications have to be introduced, and much has been written about how exactly these qualifications are to be framed.1 There is however what may be a rather more serious objection to the view that want-satisfaction is a non-instrumental good, or rather to the combination of that view with the principle that it is sufficient for your want that p to be satisfied simply that p is true. The objection is that this combination forces you to give undue weight to the mere acquisition of desires when you come to make judgements about changes in the value of things. It forces you to say that for any true proposition p, which initially you do not want to be true, your mere acquisition of a desire that p will, other things being equal, make the world better. Non-instrumental value can be increased merely by multiplying desires, even though everything else remains the same. Surely, however, improving the world is not as easy as that. (shrink)

Robert Grosseteste was a prolific theological and scientific writer, a translator, bishop of Lincoln , and a candidate for sainthood. There have been several studies of his life and his works, the most recent being that of Richard Southern. Nevertheless, James McEvoy's comment in 1983 that “the course of Grosseteste's life up until 1225 is almost completely unknown” remains largely true. The problem is common in medieval history—there is a dearth of reliable sources for the subject's early life. I do (...) not intend to discuss here Grosseteste's youth, or even his life until 1198 . I will accept, with a few reservations, the model Southern presented for Grosseteste's life until 1198 — that Grosseteste came from an undistinguished family, acquired an education, and may have taught in local schools; after serving the bishop of Lincoln in a minor capacity, he managed to obtain an administrative position under Bishop de Vere in the diocese of Hereford. Unfortunately, Bishop de Vere died on Christmas Day 1198, and his household was disbanded. It is the period following 1198 until 1225 that needs scrutiny. The recent discovery of a reference to Robert Grosseteste in a thirteenth-century cartulary demands that we reconsider the way in which historians have structured Grosseteste's career, both because of what this manuscript records and because of the light it sheds upon the methodology that has underpinned Grosseteste scholarship.

Any study of the religious situation in Ukraine always faces one problem - the lack of detailed information on the number of believers of a particular denomination. The most recent census did not include the question of denominational affiliation, as it was considered a violation of the principle of freedom of conscience. The only officially recognized statistical unit we have is the religious community. Approximate number of adherents of a particular denomination is given by the results of sociological research. However, (...) it is precisely at the border of statistics and sociology that one of the paradoxes that the current religious situation in Ukraine is rich in is the paradox of the inconsistency of sociological data with statistics. Thus, according to the State Committee for National Religions of Ukraine as of January 1, 2009, there were 11539 communities of the Ukrainian Orthodox Church of the Moscow Patriarchate, 4128 communities of the Ukrainian Orthodox Church of the Kiev Patriarchate, and 1184 communities of the Ukrainian Autocephalous Orthodox Church. As the traditional Greek churches include the Ukrainian Greek Catholic Church and Roman Catholics, their number is 3570 and 907 communities, respectively. (shrink)

Throughout history, the nature of the UGCC is at the center of the attention of researchers. Until now, they are divided into "Westerners" - supporters of Romanization of the church, that is, its purely Catholic nature, and "Byzantines" - those who defend its eastern rite. In addition, the study of the history of the Ukrainian Greek Catholic Church can be divided into two groups: negativist works and apologetic works. The first group is primarily represented by the works of Ukrainian Soviet (...) historians of the postwar period, which have very well-known names: "Unia: the path of betrayal and disgrace", "UniCity - an instrument of clerical anti-communism", "Uniate Church - enemy of the Ukrainian people", "The reactionary role of the union in the history of Ukrainian people "etc. Of course, the significance of such ideologically exacerbated "research" as a scientific development is doubtful. They have, if not scientific, but rather a journalistic character. (shrink)

Los 18 trabajos recogidos en este volumen tienen como telón de fondo una preocupación por la racionalidad occidental. Mucho se ha hablado de su crisis o de su fracaso. De ello se ha ocupado durante décadas la Escuela de Francfort, en sus distintas reencarnaciones, y, más recientemente, el pensamiento posmoderno. Lo que este libro pretende es enfrentarnos a la crisis de la razón pero desde un ángulo insólito, desde el pensamiento judío. El judaísmo hizo su experiencia de la modernidad. Sintió (...) que no tenía sitio. Algunos de los autores aquí estudiados tuvieron que plantearse, en el momento de su madurez, que había que elegir entre ser moderno o marginarse. Durante siglos, la mayoría optó por lo primero, es decir, por la asimilación. Hasta que algunos plantearon y decidieron seguir siendo judíos sin renunciar a filosofar. Con ello el judaísmo se convierte en un lugar privilegiado para valorar el pulso de la razón occidental. El judaísmo era el límite de la Ilustración. Así lo planteaban los ilustrados y así lo vivieron durante mucho tiempo los propios pensadores judíos. Hasta que les dio por pensar por sí mismos. En este libro se reconstruyen algunos de esos memorables episodios. (shrink)
