This is Not the Blog You Are Looking For

Mr. Gilroy’s classes each now have their ownblogs:

DO NOT POST HERE ANYMORE!

The Universe Episode

I think it’s cool that they have computer simulators to model what happens when different sized stars collide and fuse to become one star so they determine what certain explosions in the sky may look like. Or to see what would happen with a white dwarf colliding with our sun making it into an egg shape sun instead (killing our sun in just an hour). GO UNIVERSE!

about the movie

In the video there was a demonstration about the two starts colliding together creating a larger star. There were pictures to prove the exploding supernova, so I wonder what led the scientists to believe that two stars can collide together and create a larger star, instead of them both exploding like (which is what happens when the white dwarf came close to a large star and took its energy). What could be the evidence, since they could not have actually witnessed it, that led them to their conclusions.

ALL CLASSES: The Once and Future Blog

As mentioned in September, the addition of a blog to the class has been an experiment. One thing I’ve come to decide is that it was a mistake to mix all three classes into one blog. So now I’ve set up a new blog for each class:

(There are underscores rather than spaces in those names: “Blog_AP_Phys” not “Blog AP Phys”.)

It will be necessary to register on the new blog. This time, there is a set rule for usernames: As username, use your last name + your expected year of graduation. For example, Bob Smith (a senior) would use smith09. Jane Jones (a junior) would use jones09. Degeneracies in this system (such as two seniors named Smith) will be handled on a case-by-case basis.

You must register on the blog no later than 11:59 PM on 2008 Nov 17. Failure to do will incur a -5 point penalty on the quarter total, with an additional 1 point penalty per day. Selecting an incorrect username will cause that name to be deleted, meaning you won’t have registered; if this makes you late, the same penalty applies.

As of tonight all users will be set to “contributor” status, meaning you can read the blog but cannot create posts any longer. I will move all relevant posts to the new blogs. Sometime in February, this original blog will be deleted entirely.
