Direct/mathematics

Famous quotes containing the words direct and/or mathematics:

“As for your friend, my prospective reader, I hope he ignores Fort Sumter, and “Old Abe,” and all that; for that is just the most fatal, and, indeed, the only fatal weapon you can direct against evil ever; for, as long as you know of it, you are particeps criminis. What business have you, if you are an “angel of light,” to be pondering over the deeds of darkness, reading the New York Herald, and the like.”
—Henry David Thoreau (1817–1862)

“I must study politics and war that my sons may have liberty to study mathematics and philosophy.”
—John Adams (1735–1826)
