You know you're a physics geek when...

you look at the curved mirrored exterior of the Wynn Las Vegas resort and wonder what the focal length of the building is. Seriously, it was the first thing I thought of when I drove by the hotel.

Today's our last full day in Vegas and our last chance to cram in a few more things to see. On the docket were the Atomic Testing Museum, Star Trek: The Experience, Chinatown Plaza, dinner at the Stratosphere and Cirque du Soleil's Mystere at Treasure Island.

The first stop of the day was the Atomic Testing Museum. I have to say, this is one cool place. The museum chronicles the history of atomic weapons testing and has plenty of artifacts and models to go along with the displays. You learn all sorts of neat things like how various things associated with the blast were measured, different types of tests conducted and the tools they used. I could have spent the whole day there, but the in-laws were starting to get munchy, so we headed down to the Chinatown Plaza for more dim sum.

Star Trek: The Experience at the Las Vegas Hilton was another place I could have spent a good chunk of the day at. There's a complete timeline of the Star Trek Universe to browse through along with lots of props, models and costumes to check out. Klingon Encounter was the better of the two rides at the end, although both were pretty cool. When you're done, the gift shop has some cool Star Trek props to buy if you've got some cash to spare, or you can have something to snack on at Quark's. Lots of fun, but I could only stay there for a few hours.

We had just enough time after that to go check out the fountain show at the Bellagio (very cool. prepare to get misted depending on the wind direction) before rushing back to get dressed up for dinner at the Top of the World restaurant at the Stratosphere. Nice place, great food, fantastic view. Make sure you have lots of money to spend, because it's rather pricey. The food is good though, but the Chocolate Stratosphere we had for dessert was a little disappointing. I though the mousse was a little too dense to be called a mousse. Tasty if you like chocolate, but a little pricey at $10.

The last show of the week was Mystere at Treasure Island (forgot the tickets back at the room so we had to run back to grab the tickets after dinner) which was another good Cirque production. The big dinner beforehand had me a little sleepy though and I ended up dozing off a little bit during some of the slower parts.

We were all pooped at the end of the show, so we headed back and called it a night. Lots of packing up to do before leaving the next day.
