Through-hole plating with Polypyrrole in Printed Circuit Boards
Abstract: The goal of this paper is to investigate the use of polypyrrole (PPy) in the through-hole plating (PTH) stage of the Printed Circuit Boards (PCB) manufacturing process. The method includes: etching of FR4, in situ deposition of a thin film of PPy, resulting in a FR4/ PPy electrode.Copper plated holes of FR4 multilayer PCB specimens were analyzed with the help of optical microscopy, Scanning Electron Microscopy (SEM) and EDS analysis. Tests on polypyrrole coated and copper plated holes also included conductivity and peel strength tests. Findings show that polypyrrole can be an equally good substitute for standard methods of hole-plating methods, like the ones based on palladium, carbon or graphite. Optical microscopy results indicate that a coherent copper layer is formed on the polypyrrole modified surface of the holes. The results of the SEM analysis help understand the mechanism of copper plating and show that copper nucleation is progressing with dendrite structures on the polypyrrole surface, following high conductivity paths. Improvements of the process of the specimens’ pre-treatment, like holes desmearing and stirring of the polymer solution, were also analyzed.

From Galileo to Hubble: Copernican principle as a philosophical dogma defining modern astronomy
Abstract: For centuries the case of Galileo Galilei has been the cornerstone of every major argument against the church and its supposedly unscientific dogmatism. The church seems to have condemned Galileo for his heresies, just because it couldn’t and wouldn’t handle the truth. Galileo was a hero of science wrongfully accused and now – at last – everyone knows that. But is that true? This paper tries to examine the case from the point of modern physics and the conclusions drawn are startling. It seems that contemporary church was too haste into condemning itself. The evidence provided by Galileo to support the heliocentric system do not even pass simple scrutiny, while modern physics has ruled for a long time now against both heliocentric and geocentric models as depictions of the “truth”. As Einstein eloquently said, the debate about which system is chosen is void of any meaning from a physics’ point of view. At the end, the selection of the center is more a matter of choice rather than a matter of ‘truth’ of any kind. And this choice is driven by specific philosophical axioms penetrating astronomy for hundreds of years now. From Galileo to Hubble, the Copernican principle has been slowly transformed to a dogma followed by all mainstream astronomers. It is time to challenge our dogmatic adherence to the anti-humanism idea that we are insignificant in the cosmos and start making true honest science again, as Copernicus once postulated.

Consciousness and the End of Materialism: Seeking identity and harmony in a dark era
Abstract: “I am me”, but what does this mean? For centuries humans identified themselves as conscious beings with free will, beings that are important in the cosmos they live in. However, modern science has been trying to reduce us into unimportant pawns in a cold universe and diminish our sense of consciousness into a mere illusion generated by lifeless matter. Our identity in the cosmos is nothing more than a deception and all the scientific evidence seem to support this idea. Or is it not? The goal of this paper is to discard current underlying dogmatism (axioms taken for granted as “self-evident”) of modern mind research and to show that consciousness seems to be the ultimate frontier that will cause a major change in the way exact sciences think. If we want to re-discover our identity as luminous beings in the cosmos, we must first try to pinpoint our prejudices and discard them. Materialism is an obsolete philosophical dogma and modern scientists should try to also use other premises as the foundation of their theories to approach the mysteries of the self. Exact sciences need to examine the world with a more open mind, accepting potentially different interpretations of existing experimental data in the fields of brain research, which are currently not considered simply on the basis of a strong anti-spiritual dogmatism. Such interpretations can be compatible with the notion of an immaterial spirit proposed by religion for thousands of years. Mind seems that is not the by-product of matter, but the opposite: its master. No current materialistic theory can explain how matter may give rise to what we call “self” and only a drastic paradigm shift towards more idealistic theories will help us avoid rejecting our own nature.

The fallacy of Education as a Source of Ethics
Abstract: For centuries, the major story of enlightenment was that education is and should be the cornerstone of our society. We try to educate people to make them respectable members of society, something which we inherently relate to being “better persons”, firmly believing that education makes humans less prone to evil. Today, modern research seems to validate that premise: statistics verify that more education results to less crime. But is this picture accurate and does this mean anything regarding morality per se? This paper tries to examine the facts with a more critical eye and determine whether education is indeed a source of ethics or not. The results of the analysis show that what we understand as education is not only unrelated to ethics but can also be a factor resulting in the degradation of morality in humans. Rousseau’s arguments against science and arts are re-enforced with arguments stemming from other great philosophers and from modern experience itself. Using modern statistical analysis regarding the correlation of crime and education and through the examination of the modern regression in ethical issues, it becomes evident that education cannot and should not be a source of ethics. Knowing what is ethical is not as important as living an ethical life. Pharisees were the first to be denied the entrance to the kingdom of God. As Oscar Wilde once said, “Education is an admirable thing, but it is well to remember from time to time that nothing that is worth knowing can be taught”.

On the untrustworthiness of axiomatic-founded science
Abstract: The idea of science being the best – or the only – way to reach the truth about our cosmos has been a major belief of modern civilization. Yet, science has grown tall on fragile legs of clay. Every scientific theory uses axioms and assumptions that by definition cannot be proved. This poses a serious limitation to the use of science as a tool to find the truth. The only way to search for the latter is to redefine the former to its original glory. In the days well before Galileo and Newton, science and religion were not separated. They worked together to discover the truth and while the latter had God as its final destination, the former had God as its starting point. Science is based on the irrational (unproven) belief that the world is intelligible along many other assumptions. This poses a serious limitation to science that can only be overcome if we accept the irrationality of the cosmos. The motto “Credo quia absurdum” holds more truth than one can ever realize at first glance. There is nothing logical in logic, whereas there is deep wisdom in the irrational. For while the former tries to build castles on moving sand, the latter digs deep inside the depths of existence itself in order to build on the most concrete foundations that there can be: the cosmos itself. The only way forward is backwards. Backwards to a time when religion led the quest for knowledge by accepting what we cannot know, rather than trying to comprehend what we do not. Science was anyway based on that in the first place.
