A facial reconstruction of Homo floresiensis, a diminutive early human that may have ... Organic aerosols make up 20 to 90% of the particulate mass of the troposphere and are important factors in both climate and human heath. However, their sources and removal pathways are very uncertain, and their atmospheric evolution is poorly characterized. Jimenez et al. (p. 1525; see the Perspective by Andreae) present an integrated framework ...The variable most frequently used in tracing elephantid evolution is lamellar frequency of the molar teeth (LF), defined as the number of enamel plates in a 10-cm length of crown ().Fourteen European samples are plotted in Fig. 2, spanning ∼2.6 Ma to 25 ka, and show a largely directional trend: Rank correlation against time is highly significant (P < 0.001) ().

The timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth.

Several scientists worked over almost a century to assemble the elements into this format. Among the …1 INTRODUCTION. It would be an understatement to say that the field of science education has dramatically changed over the last 100 years. Through wars and geopolitical events, reforms, epistemological, theoretical, and methodological revolutions, and constant work by an engaged community, science education today looks much different than it did in 1920.Since evolution is an active science, this process will also highlight where there are "missing pieces" that are still being sought by scientists. All of this is well and good, since the purpose of this course is not so much to convince anyone of the validity of evolutionary theory, but rather to inform readers about the nature and scope of ...

Some models of science dynamics have attributed the evolution of fields to branching, caused by growth and new discoveries 5,6 or specialization and fragmentation 7. Examples of this kind of ...With the advent of quantum mechanics and the Schrödinger equation in the 1920s, atomic theory became a precise mathematical science.Austrian physicist Erwin Schrödinger devised a partial differential equation for the quantum dynamics of atomic electrons, including the electrostatic repulsion of all the negatively charged electrons from each …We introduce an automated method for the bottom-up reconstruction of the cognitive evolution of science, based on big-data issued from digital libraries, and modeled as lineage relationships between scientific fields. We refer to these dynamic structures as phylomemetic networks or phylomemies, by analogy with biological evolution; and we show that they exhibit strong regularities, with ... ….

In particular, the human cerebral cortex is greatly expanded, allowing accommodation of the evolutionary increases in the number of cortical ...The teaching of the scientific theory of evolution has been at the heart of numerous cases brought under the establishment clause, the free exercise clause, and the free speech clause of the First Amendment. Since the early part of the 20th century, those critical of evolution have attempted to ban it from public school curricula.A fundamentally new approach to the history of science and technology This book presents a new way of thinking about the history of science and technology, one that offers a grand narrative of human history in which knowledge serves as a critical factor of cultural evolution.

The Miller–Urey experiment (or Miller experiment) was a chemistry experiment carried out in 1952 that simulated the conditions thought at the time to be present in the atmosphere of the early, prebiotic Earth, in order to test the hypothesis of the chemical origin of life under those conditions. The experiment used water (H 2 O), … general practice attorneyskansas team statskansas vs alabama basketball In short, the evolution of science is due to a high level of functional interaction between science, technology and society over time and space. Hence, the scientific development is due to advances with parallel and integrated relationships between different scientific and technological domains.The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was first identified.
