Pocas personas acuden a una sala de cine con la pretensión de desentrañar los misterios científicos que se ocultan tras las espectaculares escenas de una película de ciencia ficción: las hazañas increibles y sobrehumanas de los superheroes, los vertiginosos viajes de naves espaciales equipadas con armas devastadoras y sistemas de defensa futuristas, maquinas del tiempo fantasticas, etc.Sin embargo, unas pocas de esas mismas personas, entre las que se encuentra el autor de este libro, deciden ir mas alla y plantearse las posibilidades reales de las ideas propuestas por los guionistas de Hollywood.

Ante la necesidad de adquirir nuevos conocimientos y definiciones concisas, este diccionario expone una serie de conceptos que instruyen a estudiantes y docentes en la mejora del proceso de la investigación científica. Las definiciones que se presentan fueron recolectadas por la autora en obras antiguas y actuales de diversas materias que, en complemento, originan conceptos generales de gran utilidad para los investigadores de cualquier profesión como: medicina, ingeniería, comunicación y contaduría, entre otras, además de incluir los símbolos matemáticos, lógicos y otros de uso frecuente en la literatura científica.

Frank Close delves into fundamental particles and forces to find clues to a deep unsolved mystery of physics why is matter neutral Human beings have long been aware of the electric and magnetic forces around us from the electrostatic charge built up by rubbing amber with fur to the pull of the lodestone and scientific investigation showed that the two are intimately connected as electromagnetism Lightning shows how devastating electricity can be in nature while humans learned to exploit the flow of negatively charged electrons that make up an electric current In the early part of the 20th century the experiments of Ernest Rutherford showed that at the heart of atoms lies a positively charged nucleus The positive charge comes from protons Atoms are neutral because the charges of the electron and proton cancel out And that enables the much weaker force of gravity always attractive to dominate at large scales building planets stars and galaxies Things would have been very different had the charges not cancelled As far as we know the charges of the proton and electron are opposite and exactly equal even though the proton is far bigger and composed of three quarks tightly bound within it while the electron is a fundamental particle But why are they

Ever since Darwin science has enshrined competition as biology s brutal architect But this revelatory new book argues that our narrow view of evolution has caused us to ignore the generosity and cooperation that exist around us from the soil to the sky In Sweet in Tooth and Claw Kristin Ohlson explores the subtle ways in which nature is in constant collaboration to the betterment of all species From the bear that discards the remainders of his salmon dinner on the forest ground to the bright coral reefs of Cuba she shows readers not only the connectivity lying beneath the surface in natural ecosystems but why it s vital for humans to incorporate that understanding into our interactions with nature and also with each other Much of the damage that humans have done to our natural environment stems from our ignorance of these dense webs of connection As we struggle to cope with the environmental hazards that our behaviour has unleashed it s more important than ever to understand nature s billions of cooperative interactions This way we can stop disrupting them and instead rely on them to renew ecosystems In reporting from the frontlines of scientific research regenerative agriculture and urban conservation Ohlson shows that a shift from focusing on compe
