Nice job as always, Dr. Larry! Thank you

Perfect sound and auditory quality!! Thanx. Material was excellent and presented in a very understandable manner. I am "hearing impaired" but I could hear every word. Please make more presentations using this quality of presentation. I wish you well, LP

Every once in a while I find a video I can actually listen too from start to finish. I like the SHORT version. Facts. Observations. Information. Not the long version of a one hour bla bla bla build up to get to the point. I see a suppressed sense of humor too, I like that. :) Get em Larry.

Very fascinating. I learned a lot here. Thank you.

very interesting and useful - thank you - wondered if you are familiar with the work of LASI at Sussex University (UK) ...
