With the semester back in full swing, the guys have their plates full. Steve and Caleb's schedules are now filled with reading, writing, lab work, teaching, and classes are keeping them both very busy. Steve talks about testing out his new force platform, the Achilles II, after weeks of design work and building. Caleb finally tells us about his purple bacteria that he found when he was in the field in Washington.

Steve shares some advice on always being skeptical of what you are taught. He spent some time going back over the anatomy of the muscles that he records from using the Achilles II. He used a book called The Anatomy of the Rat, by E. C. Greene, an amazing female anatomist from the early 20th century. Then Caleb talks about how important going back in time through the literature can be crucial for your research. Sometimes some very effective techniques can become forgotten over time.

After a long in-depth explanation of how muscle cells are organized and how they work, Steve and Caleb talk about how crazy it is that humans have figured out all of this detailed information about how the world works. They also can't believe that they get to be a part of it all. This episode is jam packed. They go all over the place but they end it with a bit of UFC talk.
