The Colbert Report Season 4 Episode 39 Dean Kamen

In season 4 episode 39 of The Colbert Report, Stephen welcomes inventor Dean Kamen to the show. Kamen is best known for creating the Segway, a self-balancing electric transportation device. As they sit down to chat, Colbert asks Kamen about some of his other inventions, including a wheelchair that can climb stairs and a portable water purifier.

Throughout the interview, Kamen emphasizes the importance of science education and encourages young people to pursue careers in STEM fields. He also discusses his charitable organization, FIRST (For Inspiration and Recognition of Science and Technology), which aims to inspire young people to get involved in science and engineering.

Colbert and Kamen also have some fun with the Segway, taking it for a spin around the studio and even attempting to ride it up onto Colbert's desk. Kamen even demonstrates a new project he's working on - a robotic prosthetic arm that has a range of motion and dexterity comparable to that of a human arm.

As always, Colbert injects plenty of humor into the conversation, jokingly asking Kamen if he's ever invented anything that "scares the crap out of people." Kamen responds by discussing his experience working on medical devices and the importance of ensuring their safety and effectiveness.

Overall, the episode is a lighthearted but insightful look at the world of invention and science education. Kamen comes across as a passionate and knowledgeable advocate for science, and Colbert's irreverent humor adds an entertaining element to the discussion.
