On March 3rd 2017, I was invited to deliver a talk on very basic rheology for the group of people mostly from Japanese cosmetic industry. As usual, there was virtually no Q&A at the end of the session. This situation is quite normal for Japanese people who have been trained to be quiet as possible during the lecture. So, I have to find another way to have their feedbacks. My favorite way is to see the number of people sleeping in the lecture room. The sleeping during lectures is another characteristics for Japanese who have been trained to stay there up to the end. Nevertheless, I found very few sleepers, so that my lecture there should be fair, I believe.
My talk there was mostly for Non-Newtonian fluids like shear-thinning fluids, shear-thickening fluids, plastic bodies and viscoelastic fluids.
Relating to this topic, I have found a nice article from NewYork Times; “How to Get Ketchup From a Bottle Without the Wait, Watery Goo and Splatter”
And, the video embedded in the article is very nice, in a sense that, the ideas of Newtonian and Non-Newtonian fluids are excellently presented. I put the link below. This video is really great and I have learned a lot for the way of conveying the idea of rheology.
