The Eye of the Beholder…

Hey guys,

I had a really hard time deciding what to talk about this week! However, what really stuck out to me was our last lecture and more particularly its format.

I felt like Tuesday we discussed how much group activity there normally is in lecture, however, on Thursday we only barely started one of the lecture tutorials. Our class was focused more on lecture, but not what I would traditionally think of as lecture.

In most of the science courses I’ve taken here at Vandy (which have been many as a pre-med physics student), lecture consists of professors talking at me while I scramble to copy what they are writing on the chalkboard (or presenting in a powerpoint). What was interesting to me about Thursday’s lecture (and what I’ve noticed in all of the “mini” lectures we’ve had so far) is that Dr. G doesn’t really write a whole lot in a powerpoint or even on the board. Do you think she does this in an effort to make us pay attention to what she is saying? Does this keep us more engaged? Or is it an attempt to make sure people attend lecture?

The other thing about Thursday in particular that stuck out was the use of visuals. We talk a lot about how big the universe is and how hard it is to comprehend the scale, but Thursday’s lecture included a lot of models and physical demonstrations. Did this help you understand scale? Clear up any issues you had with the reading?

And lastly, why this idea really caught my attention, I’ve always heard of different learning styles- people will claim to be auditory or visual learners. Do you think there is any truth to learning styles? Does Dr. G do a good job of catering to all of them or do you feel that any particular style would feel left out?

(If you have no clue what I’m talking about or would like to read more about the debate over learning styles and their validity, this wikipedia article is a good place to start)

2016 Planetary Alignment!

As described in class, here are my two favorite articles about this alignment:

Get Up Early, See Five Planets at Once! from Sky and Telescope

How to View Five Planets Aligning in a Celestial Spectacle from The New York Times

I happen to adore the NYT diagram because it shows the Solar System view as well as the view from Earth:

Planet Nine!

Caltech Researchers Find Evidence of a Real Ninth Planet

This is legit folks!  For those who are at a university (like Vanderbilt), this press release has a link to the actual research article in the Astronomical Journal.  It’s a bit heavy at times but well done.

There’s also a pretty good article on Wired: This Isn’t the First Time Astronomers Have “Found” a Planet Nine

P9_KBO_orbits_labeled-NEWS-WEB

(from the press release) The six most distant known objects in the solar system with orbits exclusively beyond Neptune (magenta) all mysteriously line up in a single direction. Also, when viewed in three dimensions, they tilt nearly identically away from the plane of the solar system. Batygin and Brown show that a planet with 10 times the mass of the earth in a distant eccentric orbit anti-aligned with the other six objects (orange) is required to maintain this configuration.

Hello!

This is me. This blog works. I love science, writing, singing, and enjoying the time I have to spend with my family (because I’m an international student from Lebanon, I don’t have a lot of it!)

Saturn’s Titan doesn’t have it’s own magnetosphere!

So whilst finding out some information about Saturn’s orbiter Cassini, I came across this story: Cassini Catches Titan Naked in the Solar Wind.  We’ve been talking a lot about magnetospheres when we discuss the giant worlds so this whole thing is really interesting!

The space probe Cassini was going by Titan in 2013 when a big solar storm hit Saturn’s magnetosphere and compressed it.  This left Titan without the protection of that magnetosphere.  According to the newly published data, Titan has no appreciable magnetosphere because particles interacted with its atmosphere just like the particles in the atmospheres of Venus and Mars (no magnetospheres due to not spinning fast enough and solid core, respectively).  The scientists interviewed for the article talk about how this information shows them that computer models developed for closer worlds can still be used for worlds farther away and that’s awesome 🙂  I love the Universe 🙂

My favorite tides

DIFFERENTIALS!! 🙂

During class today, I talked about tides and how there is a great deal of misinformation out there.

My favorite websites for the astronomical explanation of tides are:

The YouTube videos of the awesome spring and neap tides in Clovelly.

Here’s a great animation about tides from the Nebraska ClassAction collection of Astronomical Simulations and Animations.
