Here's my answer (albeit a bit fantastic)… Let’s assume that Vibranium is a lattice structure of some sort.  Kinetic energy (maybe other forms as well like heat and radiation) hitting perpendicular to the lattice is absorbed completely without loss.  This energy is stored in the lattice.  We’ve seen instances of the energy expanding from the center of the shield, so maybe the energy naturally propagates to the outer edge of the lattice.  This stored potential is released when impacted with energy parallel to the lattice (i.e., hit the edge of the shield).  This would explain 1) why the shield bounces when thrown, 2) why more energy is released when bouncing than put into the throw (i.e., hit the Hulk and release previously stored energy to throw him), and 3) why we see an explosive reaction on the plane of the shield when hit with Thor’s hammer (the hammer’s kinetic energy is too much to store in the shield’s lattice)

Take a look, it's in a book!

+Levar Burton just launched a #kickstarter  campaign to relaunch #readingrainbow  on the web.  Pretty much anyone under the age of 35-40 has fond memories of Reading Rainbow, so I expect this kickstarter to be WILDLY successful.

But don't take MY word for it, check out the link below. ;-) 
Drop everything: LeVar Burton wants to resurrect Reading Rainbow, and he wants it as universally available as possible. So this morning, he launched a Kickstarter, aiming to raise a million dollars to fund the development of a web version. That great swooshing sound you just heard was the entire Internet opening its wallets simultaneously.

WOOHOO! Congrats +Levar Burton !

College Students Exposed to "Common Core" Math

"Common Core" curriculum has been in the news recently, with examples of extremely tedious math problems being widely circulated.

Here's an interesting video showing a Common Core math problem to college students, and their reactions. I think school kids would have an easier time learning matrix algebra than this convoluted method of performing simple math.  What are your thoughts on Common Core?

Hehe, sorry. It should be 520++. Start from the smaller bounds and expand outwards (easier than subtracting inwards).

Happy Star Wars Day!

Did you know today is officially Star Wars Day?

Here's a special +NASA video which includes a cameo by none other than R2-D2! May the fourth be with you!

Five Ways to Get Blocked on Google+

From the home office in Sioux City Iowa, here's the top five things that will get you blocked. 

5.) Random invites to hangouts.

4.) Invite to a marketing spam page.
3.) Invite to a Google+ community that isn't relevant to a person.
2.) Post comments that have absolutely nothing to do with the topic, or consist of one or two words that don't contribute value to the conversation.

1.) Post hateful comments and/or comments that are disrespectful to others.  

Seriously folks, this holds true for anyone you circle on Google+, or any other form of social media. Take 30 seconds and read their about page. Mass spamming people with invites will NOT build your brand.

Taking the time to engage with others isn't a sure-fire recipe for success, but it sure beats pissing everyone off and getting blocked/reported/banned.

How I Feel On The Internet Today

As someone who is generally uninterested in professional sports (except for Rally Racing), this is pretty much me during   #worldcup2014  

h/t to +Matthew Inman / The Oatmeal.

Also generally uninterested. Last World Cup I really surprised myself and got excited about football. New Zealand doesn't qualify often but I feel quite sad we are not there this time.

Comets, Asteroids, and Meteor Showers, oh, my!

Lately I've been asked "how do you discover asteroids and comets?"

The process is rather simple, and made easier through the use of digital imaging and computer processing.  My group takes several images in an area of the sky, and then we overlay the images, using the background stars as a guide.  

Anything that is moving against the background stars in certain directions and velocities is flagged by our system as a potential object. The software isn't 100% accurate, which is where us astronomers come in. We review these images real-time and sort out what's real from what's not. 

Speaking of meteors, asteroids, and comets, there might be a new meteor shower this saturday morning. - Look due north just after midnight local time. We might be in for a treat!

*PS the object below is a real object.

Catch Chris Hadfield's performance of David Bowie's "Space Oddity!"

When +Chris Hadfield sang  #spaceoddity  aboard the ISS, and put it up on YouTube, the license was only for one year, which expires today!

Catch the video while it's still available!

Not a bad way to make your own saber hilt, especially since many vintage camera dealers WON'T sell Graflex/Heiland flashes if they know they'll get cut up.

Home Depot and Lowes are ideal places to search for light saber parts. That's pretty much where I got all the parts I needed.

Official Cast Announcement for Star Wars Episode VII!

Earlier today +Star Wars announced the cast of the highly-anticipated 3rd Star Wars Trilogy:

The Star Wars team is thrilled to announce the cast of Star Wars: Episode VII.

Actors John Boyega, Daisy Ridley, Adam Driver, Oscar Isaac, Andy Serkis, Domhnall Gleeson, and Max von Sydow will join the original stars of the saga, Harrison Ford, Carrie Fisher, Mark Hamill, Anthony Daniels, Peter Mayhew, and Kenny Baker in the new film.

Director J.J. Abrams says, "We are so excited to finally share the cast of Star Wars: Episode VII. It is both thrilling and surreal to watch the beloved original cast and these brilliant new performers come together to bring this world to life, once again. We start shooting in a couple of weeks, and everyone is doing their best to make the fans proud."

Star Wars: Episode VII is being directed by J.J. Abrams from a screenplay by Lawrence Kasdan and Abrams. Kathleen Kennedy, J.J. Abrams, and Bryan Burk are producing, and John Williams returns as the composer.

I'm pretty excited about this, despite how badly JJ mucked up Star Trek, I think he'll do well with the Star Wars franchise. Considering Lawrence Kasdan is working on the script, and the original trilogy cast is in the movie, it should be good.

Just Googled that lot to find out more.  It's interesting that, out of the 7 newcomers, 4 are from the British Isles and one is Swedish!

John Boyega was okay in Attack the Block but I'm not sure how he'll cope with something as big as SW.  I suppose it depends on the character he's playing.

Daisy Ridley is very new to film & TV acting, but what I've seen of her so far has been excellent.  She'd make a great daughter to Han & Leia in character, but the accent might be a problem for that role...

We all know Andy Serkis, at least in voice (Gollum, King Kong, Caesar from Planet of the Apes, etc.) so he's certainly got the acting chops for this.

Domhnall Gleeson is also pretty well known and accomplished, so that's all good.  I can see him as another Kenobi.

Finally, Max von Sydow.  Wow, there's a presence!  I hope this dude plays a bad guy!  Liet Kynes and Vigo, enough said.

Bringing space back down to Earth!
After nearly two decades in Information Technology, I made the leap from "backyard" to "professional" astronomer. I observe and catalog asteroids in our solar system, and have two publications on variable stars. I also assist with various astronomy education and outreach efforts. 

I've blogged for Universe Today, , the Planetary Society , and my own blog, Dear Astronomer. I was co-director of outreach for Yuri's Night 2012, and am currently a NASA/JPL Solar System Ambassador. I also do outreach and informal education at CosmoQuest. You can follow me on twitter at: @cosmic_ray

During what little spare time I've got, I play guitar, "paper and dice" role-playing games, table top games, and pursue all things nerdy/Sci-Fi. 

Add me to your circles if you are a fan of space exploration, science fiction, and all things nerdy. My shenanigans are cheeky and fun!

Contrary to popular belief, I did not destroy 3/4 of a star system... more like 5/6 - it's not an exact science.
