Quote by Johannes Kepler

"Geometry will be a powerful instrument in our hands for knowing God's omnipotence."

"I much prefer the sharpest criticism of a single intelligent man to the thoughtless approval of the masses."

"Truth is the daughter of time, and I feel no shame in being her midwife."

"I believe in working hard for what you want."

"Never underestimate the power of determination."

"I don't need a reason to fight."

"The most important thing is the mission. Nothing else matters."
