Then we left to meet back up with the group, stopping for some fresh peaches on the way! Once we were all together, we headed to the train/metro station to visit the Bovisa Campus of Politecnico Milano, a technical university in Italy ranked #21 in the world for engineering! Our visit started with a basic presentation and some free gifts where they explained their international exchange program and what degrees they offer. All their masters degree courses are offered in English to attract a wide variety of international students. The craziest part was that their tuition, even for a graduate program, was 3500 euro per year! On a bad day, that's like $6000. My jaw actually dropped and the presenter started laughing saying, "Yes different from United States!" Maybe if I decide I need more schooling after my 5.5 years in undergrad (not likely), I'll just come over here!
Then we had a presentation from an assistant professor who worked on the Rosetta mission, where they attempted to send a piece of equipment to analyze the comet and its components. After four gravity assists (three from earth and one from mars) and ten years, the equipment made it to the comet's orbit in 2014. The next challenge was hitting a 100m target on a rotating comet from 20km away...and to make things more interesting, the comet was a completely different shape than what they expected. They ended up missing their target by a hair which caused the lander to bounce twice and settle over a "cave" type terrain. This was a problem for two reasons: there wasn't enough consistent sunlight at this point to recharge the lander's batteries and it wasn't centered over terrain, so it could not drill down to get a sample of the comet. Due to certain trade offs, the lander wasn't mobile so the mission was a bust. Since the batteries have died, they've made contact with the lander one time mid 2015, but haven't reached it since. Obviously this is the summary of what happened because the presentation was an hour long, but it was really interesting to hear from someone so invested in the project tell us about its failure. He had a wonderful attitude about it and kept saying, "There are many lessons learned from this." Because of their failed expedition, two more missions are now able to make contingency plans in case that were to happen on their expedition. That's one of the things I love about science and engineering - even in failure, there are many successes.
The third portion of the visit included a visit to the wind tunnel, which PoliMi (like our CoMo!) uses to test all sorts of specific aerodynamics - for sports wear, bridges, trains, planes, stadiums...so many things! They've even tested an airplane that takes off like a helicopter and then rotates its wings to fly like a plane! The future is here people. The wind tunnel uses scale models with equivalent strengths of materials to figure out the effects of wind speed, angles, and directions. A lot goes into making a model before the actual testing happens!
Finally, we got to talk to current graduate students at PoliMi and hear about what their studying. I talked to the electrical engineer about his work in the power industry where the systems can be reworked so that if people fail to pay their electric bills, their power can be cut off remotely instead of sending a person to physically do it. The U.S. and Italy have both done this, but many countries have not and its much more costly to pay a person for what a computer system can do now. He was very passionate about electrical engineering so he was interesting to listen to, even though I'm not sure I'm specifically interested in what he's studying.
I took a break after the visit to rest a little bit, and then went out for dinner. I wasn't super hungry so I ended up having bruschetta and limone schweppes. I was so hungry I forgot to take a picture of it before scarfing it down (I know, my priorities were totally messed up) but it was so good! The fresh ingredients here continue to impress me every day. Just another day in Italy! Tomorrow we're off to Florence - our last city! I can't wait to see yet another amazing city in this beautiful country!
We didn't see a whole lot of picturesque things today so there are only a few pictures.
Some cool free stuff!
