- QI has been unable to find this precise quotation in the writings of Ayn Rand. However, QI hypothesizes that the sentence was derived from a dialog in her best-selling 1943 novel “The Fountainhead”.
The question isn’t who is going to let me; it’s who is going to stop me.

- Mesoproterozoic (Wikipedia)
The Mesoproterozoic Era is a geologic era that occurred from 1,600 to 1,000 million years ago. The Mesoproterozoic was the first era of Earth’s history for which a fairly definitive geological record survives. Continents existed during the preceding era (the Paleoproterozoic), but little is known about them. The continental masses of the Mesoproterozoic were more or less the same ones that exist today, although their arrangement on the Earth’s surface was different.
