Welcome to the Physical Sciences Portal! This page connects browsers to the learning materials that have been developed by the various Wikiversity Physical Sciences content development projects. This portal features exciting examples of Physical Sciences learning resources.
The content development projects are the schools, departments and divisions linked to from this page. Wikiversity participants who are interested in the Physical Sciences are invited to create and develop learning projects and learning resources and help organize access to them by developing this portal.
The star HD 209458 has an extrasolar planet orbiting it.
The Observational astronomy learning project has activities for participants that guide them through the same process that an astronomer uses to analyze data. Participants in the Extrasolar planet project explore telescope data to find planets orbiting distant stars. The goal is to create a learning group where participants can compare notes and document the search process and to create an extended learning activity about exoplanets. No prior experience is needed; participants get step by step instructions on how to get started.
The Euler-Lagrange equation of classical mechanics was discovered during attempts to find a curve for which the time taken by a frictionless particle sliding down it under uniform gravity to its lowest point is independent of its initial starting point.
"We must not forget that when radium was discovered no one knew that it would prove useful in hospitals. And this is a proof that scientific work must not be considered from the point of view of the direct usefulness of it". - Marie Curie
