This is the entire video I started today in class. I’ve spoken about many of the locations in this video, and it illustrates much of the information we covered in class.

Dynamic Earth Web Assignment
Sorry this post is late guys, so I’m extending the due date to Monday, October 6. And yes, the assignment is Sedimentary Rocks, not Igneous Rocks.
What Drought is Doing to California
As mentioned in Dynamic Earth Class. The “slider” effect really shows the change.

Dynamic Earth – Web Assignment #1
Here it is…
Please ignore the August 2012 due date, I haven’t updated the web page.
The Most Important Video You Will Ever See
Greetings! Here is the promised link to Dr. Bartlett’s lecture. I mistakenly said the Dr. Bartlett was still alive, sadly he passed away last September.
Here is the whole playlist if you want to watch all the segments.

And here is his entry in Wikipedia
Creep Leads to Retaining Wall Collapse in Baltimore
Doesn’t sound as good as “Landslide in Baltimore” but it’s more correct. Recent rains caused extra pressure on a retaining wall next to railroad tracks. The wall begins to give way slowly, by around 1:10 the fun starts.
And here’s a link to some cool pictures…

Cosmos is on HULU!!!
Awesome! I forget who told me this in class (thank you Ramneet) but I am thrilled. I missed the second episode, but was able to watch it in HD on hulu. Here is the link for all three episodes so far….
Saturn Has an Aurora
Wow, and before you tell me the images are grainy, remember, this is from a probe we humans put around Saturn! Saturn’s northern and southern lights glow in red on the bottom and purple on top in visible light, according to Cassini photos.

WHAT?!
Okay, this makes me mad.
Quarter of Americans Convinced Sun Revolves Around Earth, Survey Finds
This year marks 45 years since we put a human on the Moon, and 54 years since the first human orbited the Earth. How is this possible? In all my years of teaching, I have NEVER met a kid who thought the Sun went around the Earth, not one. Frankly, I doubt I’ve met many adults who thought that either (and like most folks, I’ve met some really dumb people). Anyone who doesn’t understand how the Earth orbits probably can’t blame it on our educational system. Certainly not in a state like Ohio where it has been taught since long before I was born. This is ignorance by choice.

The Oldest Star We Have Ever Found
Earth in the Martian Night Sky
Mars rover Curiosity snapped this photo of Earth (and the Moon) high in the Martian sky. You can see it much clearer in the larger size (click on the link). Humans can be amazing sometimes.

Is This the Timeline for Our Future?
The BBC has created this infographic to illustrate some predictions on the far future. All the way to 100 trillion years from now. Not sure I buy a lot of it though.

R.I.P. John Dobson
One of the oddest, most interesting characters in amateur science. He revolutionized home astronomy and taught thousands of people how to make powerful home telescopes, he died on January 15th at 98.

Winter in Antarctica
Well it looks like we’ll be seeing some truly cold weather as school starts back up. It’s summer in Antarctica right now, but it’s a good time to reflect on how cold it can get on our planet (remember, being in the Southern Hemisphere, their winter is during our summer). Few scientists can take wintering on the Antarctic continent. The population of the whole continent drops to only a few hundred over the winter and they must pass a rigorous screening process before they are allowed to do so. The video below shows what “Condition 1” weather is like. No travel outside quarters is permitted during these conditions.
Makes you feel warmer already, doesn’t it?

“The “Super Ball Bot”, under development at NASA Ames, is a robotic exoskeleton designed to land on the surface of Titan without a parachute or airbag.”

Since we have discussed this in Dynamic Earth, I came across this story and immediately thought, “Cave diving is crazy dangerous.”
