The wobbly beam of the Vela pulsar
At the center of the Vela supernova remnant is a madly spinning neutron star. It spins *11 times per second*, which helps it whip up a magnetic field so fierce it can actually defy the gravity of the star, which is a billion times stronger than Earth's! All of this help it generate two beams of matter and energy that blast away from its poles. Recent observations of this beam show that it appears to be wobbly, making a corkscrew motion over a period of 120 days. This movie is made from 8 images

Keywords have been more than ways of seeing: they have been influe

12.333 Atmospheric and Ocean Circulations (MIT)
In this course, we will look at many important aspects of the circulation of the atmosphere and ocean, from length scales of meters to thousands of km and time scales ranging from seconds to years. We will assume familiarity with concepts covered in course 12.003 (Physics of the Fluid Earth). In the early stages of the present course, we will make somewhat greater use of math than did 12.003, but the math we will use is no more than that encountered in elementary electromagnetic field theor

3.1.1 The cause

A small digression will be made here to question the use of the word ‘cause’ and to reflect on the view expressed by Kletz (1988, p. 2). He argues that the word has an air of finality about it, and is concerned that finding the cause discourages further investigation. He cites an example that the cause of a pipe failure was corrosion – which suggests that we know why the failure occurred. He draws the analogy of the cause of a fall being gravity – suggesting that nothing more can be d
