Scientific American is the essential guide to the most awe-inspiring advances in science and technology, explaining how they change our understanding of the world and shape our lives.

The arrival of Albert Einstein in Argentina in 1925 had an impact, equally relevant, on the scientific community and on the general public. In this paper we discuss that visit from three different perspectives. Firstly, we consider the conditions that allowed for such visit to be possible. Then we focus on the institutional actors that facilitated it, as well as on the expertise and written references on topics related to relativity theory circulating at the time in the local community. In the last section we consider the implications of that visit for the local scientific environment.

The scientific method refers to ways to get facts, correct errors and mistakes, and test theories. The Oxford English Dictionary says that scientific method is: "a method or procedure that has characterized natural science since the 17th century". It is observation, measurement, and experiment, plus the formulation, testing, and modification of hypotheses. A scientist gathers empirical and measurable evidence, and uses sound reasoning. New knowledge often needs adjusting, or fitting into, previous knowledge. Criterion What distinguishes a scientific method of inquiry is a question known as the criterion'. It is an answer to the question: is there a way to tell whether a concept or theory is science, as opposed to some other kind of knowledge or belief? There have been many ideas as to how it should be expressed. Logical positivists thought a theory was scientific if it could be verified (proved true). Karl Popper thought this was a mistake. He thought a theory was not scientific unless there was some way it might be refuted (shown to be wrong). On the other hand, Paul Feyerabend thought...

Science magazine has chosen “the seemingly unstoppable growth of renewable energy” as the most notable scientific advance of 2025. The journal highlights that this year was the first in which solar and wind energy surpassed fossil fuel-based energy in certain areas. In this transition, Science highlights the role of China, which now dominates global production of solar panels, wind turbines, and lithium batteries, and has managed to make renewable energy technology cheaper. Among the obstacles, the magazine cites the continued widespread use of coal and political resistance in countries such as the United States.

Le methodo scientific es le studio systematic, controlate, empiric e critic de propositiones hypothetic super allegate relationes inter differente phenomenos natural e es le mechanismo empleate in le scientias experimental pro validar o invalidar un theoria, per medio del experimentation o del observation. Il ha duo pilares basic del methodo scientific. Le prime de illos es le reproducibilitate, in altere parolas, le capacitate de repeter un determinate experimento in qualcunque loco e per qualcunque persona. Iste pilar emplea pro su practica, essentialmente, le communication e le publicitate del resultatos obtenite. Le secunde pilar es le falsificabilitate (refutabilitate). In altere parolas, que cata proposition scientific debe haber le possibilitate de esser falsificate (refutato). Isto implica que on pote designar experimentos que in le caso de dar resultatos differente al predicite negarea le hypothese que on verifica. In le actualitate le resultatos del recerca scientific es publicate in revistas scientific specialisate post criticas o commentarios de altere expertos, correctiones ab le autores e etiam verification del experimentos per altere...

Some of the most remarkable scientific breakthroughs in the field of medicine and healthcare have the potential to improve medical treatments

Digital Repository of Scientific Institutes (RCIN) was established and is being developed mainly as an outcome of two projects acquired and jointly accomplished by a group of Polish scientific institutes.

Scientific formalism is a family of approaches to the presentation of science. It is viewed as an important part of the scientific method, especially in the physical sciences. Levels of formalism There are multiple levels of scientific formalism possible. At the lowest level, scientific formalism deals with the symbolic manner in which the information is presented. To achieve formalism in a scientific theory at this level, one starts with a well defined set of axioms, and from this follows a formal system. However, at a higher level, scientific formalism also involves consideration of the axioms themselves. These can be viewed as questions of ontology. For example, one can, at the lower level of formalism, define a property called 'existence'. However, at the higher level, the question of whether an electron exists in the same sense that a bacterium exists still needs to be resolved. Some actual formal theories on facts have been proposed. In modern physics The scientific climate of the twentieth century revived these questions. From about the time of Isaac Newton to that of James...
