Neil deGrasse Tyson (@neiltyson) retrieves a dollar bill from his wallet to make a point about the U.S. budget for research and development
"You can take a dollar and cut off this edge but don't get into the ink. Then cut off the other edge and don't get into the ink. Those two amounts of this dollar, that's the R&D budget of the United States. The rest is everyone complaining that our economy is losing ground in the world." -Neil deGrasse Tyson (@neiltyson)
