    What a surgeon. His treatment of DNA replication with sensitivity to physics, mathematics, and biochemistry are more remarkable than most people realize. Dr. Lander, we are truly spoiled

    You know if rep-rap or some other 3D printers could print out several smaller versions of themselves, then those smaller 3D printers could print smaller versions and so on (sort of like the broomsticks in Disney's fantasia) until you get to the molecular scale and you can build 3D print enzymes, protein builders, and DNA in a controlled way O_o.

The way Professor Eric makes this inherently complex process sound so simple and harmonious is so interesting. Hopefully, I'd imbibe some of his teachings and pass onto my future students.

    David Chen the way this professor teaches is so much more clear and effective. The powerpoint slides a lot of instructors use have too much information for your brain to process. Him writing the information as he tells it to you makes him slow down the information to the same speed as a student can take it in. He’s also very logical and explains the rationale behind things. He seems like an awesome instructor!

    @@tasmaniandevil6750 modern topics, especially those in proteomics/biochemistry can't be drawn quickly and the class covers less materials. You can cover much more material in a powerpoint, and students are better prepared for graduate school. If I had to wait for my biochemistry prof to finish drawing all the structures of AA's or other metabolites (especially complex ones like steroids), we probably wouldn't get very far.

    I'm blown away by this mans teaching style. I always assumed professors at the university level were not as attentive or worried about making the class interesting, but here I am, sitting through the whole video entranced about the subject. This does not comapre to the education I'm receiving at a community college.
