Crossed molecular beam experiments are chemical experiments where two beams of atoms or molecules are collided together to elucidate the dynamics of the chemical reaction, and can detect individual reactive collisions.
Famous quotes containing the words crossed and/or beam:
“What I have crossed out I didn’t like. What I haven’t crossed out I’m dissatisfied with.”
—Cecil B. De Mille (1881–1959)
“What do we plant when we plant the tree?
We plant the ship that will cross the sea,
We plant the mast to carry the sails,
We plant the planks to withstand the gales—
The keel, the keelson, and beam and knee—
We plant the ship when we plant the tree.”
—Henry Abbey (1842–1911)
