Flutter Induced By Dry Friction
It may seem surprising that aeroelastic flutter is a phenomenon sharing similarities with instabilities due to friction. This was recently experimentally discovered by Bigoni and Noselli (2011), who have produced a follower force through dry friction at the contact between two sliding bodies, see the animation on the right and watch a movie for more details.

“After the brief bivouac of Sunday,
their eyes, in the forced march of Monday to Saturday,
hoist the white flag, flutter in the snow storm of paper,”

“Few can be induced to labor exclusively for posterity; and none will do it enthusiastically. Posterity has done nothing for us; and theorize on it as we may, practically we shall do very little for it, unless we are made to think we are at the same time doing something for ourselves.”
—Abraham Lincoln (1809–1865)
“If you are one of the hewers of wood and drawers of small weekly paychecks, your letters will have to contain some few items of news or they will be accounted dry stuff.... But if you happen to be of a literary turn of mind, or are, in any way, likely to become famous, you may settle down to an afternoon of letter-writing on nothing more sprightly in the way of news than the shifting of the wind from south to south-east.”
—Robert Benchley (1889–1945)
“The admission of Oriental immigrants who cannot be amalgamated with our people has been made the subject either of prohibitory clauses in our treaties and statutes or of strict administrative regulations secured by diplomatic negotiations. I sincerely hope that we may continue to minimize the evils likely to arise from such immigration without unnecessary friction and by mutual concessions between self-respecting governments.”
—William Howard Taft (1857–1930)
