Thank you, glad that you found it interesting.   

Dear Professor @Moshe Deutsch , thank you for sharing this.  It is so elegant, so beautiful ! 

@Moshe Deutsch Thank you for your kind comment. The biblical verse that inspired Reiner's definition of what is now known as the Deborah number. Reiner  quoted Prophetess Deborah as  saying, 'The mountains flowed before the Lord' [1]. As I pulled up some further literature, I see  it indeed contrasts with the King James version that states, 'The mountains melted from before the Lord' - which you have rightly pointed out.   I imagine that the verse may have a different context and scope, yet, Reiner's use of it to define the Deborah number is intended to indicate the fluidity of materials at different time scales. A famous example of which is the pitch ball drop experiment. Thank you again for the note.
