This collection of videos was created in ~1969 to explain fluid mechanics in an accessible way for undergraduate engineering and physics students. See http://web.mit.edu/hml/notes.html for notes associated with these videos.

In these Messenger Lectures on "The Character of Physical Law," originally delivered at Cornell University and recorded by BBC Nov. 9-19, 1964, physicist Richard Feynman offers an overview of selected physical laws and gathers their common features into one broad principle of invariance. From 1945 to 1950, Feynman taught theoretical physics at Cornell. He went on to accept a professorship at Caltech and was named co-winner of the 1965 Nobel Prize in physics.
Admissions in Fall 2020 to the PhD program at Mahindra University are open. Application deadline is 20 June.

Hello,
I have defined general shell section properties in my model in Abaqus. When I run the simulation, there's no stress out put data available. What could be the reason for this?
Challenge yourself to snap a spaghetti stick in half by bending two ends. It always snaps into three or more pieces, but not two. But why? Indeed this phenomenon has puzzled many people, including the great Richard Feynman, for many years. The puzzle was only solved in recent years. Slow mo videos by ultrahigh speed camera reveal why.

Dear iMechanicians,
I hope the present work is of interest to you. We present a new formulation for resolving the electrochemical-diffusion interface in hydrogen embrittlement modelling
