Radiation astronomy/Courses/Principles/Syllabus/Spring

For those wishing to take a formally structured undergraduate university semester-length course, this is the Spring offering for principles of radiation astronomy. Resource titles here are conventional although the actual resource may appear slightly different. For example, X-ray astronomy has been changed to Radiation astronomy/X-rays which is a suggestion for naming resources. See Wikiversity:Naming conventions which is a proposal. There are no consensus approved naming conventions at Wikiversity. Re-directs will automatically take you to each resource.

General course details may be found at the Syllabus.

"Scientists have found minerals formed near the sun or other stars in the samples returned to Earth by NASA's Stardust spacecraft in January [2006]."[1]

"The interesting thing is we are finding these high-temperature minerals in materials from the coldest place in the solar system."[2]

"We have found very high-temperature minerals, which supports a particular model where strong bipolar jets coming out of the early sun propelled material formed near to the sun outward to the outer reaches of the solar system."[3]

"It seems that comets are not composed entirely of volatile rich materials but rather are a mixture of materials formed at all temperature ranges, at places very near the early sun and at places very remote from it."[3]

Spring hits for 30 d periodEdit

For some 219 course resources such as laboratories (L), lectures, mini-lectures, lessons, problems, and quizzes, the total hits over the 219 elements was 9302 for the last full week in February combined with the first full three weeks in March.

The breakdown per course elements was laboratories (L), 1.96 %, lectures, 76.1 %, lessons, 4.38 %, problems, 2.57 %, or quizzes, 14.9 %.

Highest individual course element is Mathematical astronomy at 1,007.

Alternate examinations that may be used by your college or university for credit (and a grade) in this course will be available from Wikiversity by courier for closed, proctored session testing of proficiency.

HypothesesEdit

  1. Courses offered in the Spring have higher student participation than ones offered in the Fall.
