All stars are formed from the material that was available to them before they collapsed. Not all stars go supernova, but those that do will populate the interstellar medium with metals that were produced in the star during its lifetime. There are actually many different kinds of supernova and...
It is well known in electrodynamics that a changing electric field causes a changing magnetic field and vice versa. If you created a scheme whereby you created an oscillating electric field, then an orthogonal oscillating magnetic field would also be created, so that you are making photons. The...
This is yet another good question.
In my last post, I determined that whether or not a gas cloud will collapse has to do with its initial temperature and density. Keeping this in mind, we can explain why some stars are born larger than others. The larger stars were born in larger gas clouds...
Hello daisey,
You bring up an excellent point! Normally, we are accustomed to thinking of gas as a crazy concoction of fast-moving molecules that are weakly interacting (i.e. an ideal gas). In the case of stellar formation, there are actual a couple of extremes we must consider. I will go...
After a lot of experience tutoring students in your position, I often find that students better understand the concepts of trigonometry by drawing the problem they're trying to solve. The human mind is able to more naturally see connections when aided with visuals!
Perfect practice makes...
