Fun

If you watched the 55th Grammy Awards one week ago, you saw the alternative rock band named Fun (stylized as fun.) perform live. I have become a fan of this band, a group that less than one year ago was playing in front of small audiences. In April 2012, Fun was at the Fort Collins Aggie Theater, a music venue that holds 650 people. The cost to see them: $15. A week ago, they performed in front of 28 million. The band took home two Grammy Awards, including Best New Artist, from six nominations.

I was lucky to see Fun live on December 13, 2012 in Broomfield, Colorado, near Denver. The arena holds 6,500 people, making it the largest audience for Fun, at the time. Our daughter and her friend allowed me to join them at the concert, something that would have been difficult for me to do when I was her age. The music and performance were excellent! It was band’s final performance of 2012.

If you have not seen or heard Fun, it’s not hard to find video clips of them at YouTube. One that stands out is a special acoustic version of We Are Young, a composition that won the Grammy for Song of the Year. Janelle Monáe joins lead singer Nate Ruess in some of the best vocals and music I’ve heard in years by any group or musician.

Yesterday, I tried to buy tickets for an August 2013 Fun concert at Red Rocks, a spectacular outdoor amphitheater on the west edge of Denver. My only time at Red Rocks was a short day visit in 1976. I have always wanted to attend a concert there, but it may not happen in August. I was unable to secure tickets, even though I tried the minute they went on sale. This is an indication of how far the band has come in such a short time.

SolidWorks World 2013

I attended SolidWorks World 2013 last week in Orlando, Florida, and it was another excellent event. About 4,500 people were in attendance. For me, two of the highlights were presentations by Vijay Kumar, an engineering professor at the University of Pennsylvania, and Elias Knubben, head of Corporate Bionic Projects at Festo.

Kumar shared the impressive work by him and his students. They have designed flying robots that are equipped with sensors and other devices that give them some intelligence. The aircraft, which can fit in the palm of a hand, can fly into buildings and tight places and gather information using small cameras. A likely application is search and rescue after a natural disaster. Another is going into areas where enemies and other threats may exist. Swarms of robots can fly in formation and avoid collision with one another—something I found particularly interesting.

Knubben of Festo showed some extraordinary parts and products, such as robot grippers made by laser sintering, a popular method of additive manufacturing. The gripper itself does not look all that interesting, until it is used. When instructed, the gripper flexes and wraps itself around an object, such as a piece of fruit, before picking it up. Knubben was kind enough to give the gripper to me and I found the design surprisingly simple, but effective.

Knubben’s team at Festo also designed a large bionic bird, called SmartBird, and it flies by flapping its wings. Knubben had the bird with him on stage. When it started to flap its wings, he gently flung it into the air and it began to fly. SmartBird circled the ballroom a couple times before landing in Knubben’s hands. I had never seen anything like it. Similar to Kumar’s small aircraft, many parts of the bird were designed with SolidWorks and produced by laser sintering.

Attending SolidWorks World was again worthwhile. If you want to get an update on the latest in SolidWorks software, applications, and company, it is the event to attend. The morning speakers are usually very good, although no celebrities made appearances this year. The exhibits are also worth some time. SolidWorks World 2014 is January 26-29 in San Diego, California.
