1 " The telescope, in enabling us to look far out into space, also allows us to look back in time. Light travels at about 186,000 miles per second. When we look up into the daylight sky, we are not seeing the sun as it currently is but as it was about eight minutes ago, since it takes that long for the light radiating from this familiar star to travel 93 million miles to Earth. Similarly, when the Giant Magellan Telescope (GMT) receives light waves from the depths of the universe, those waves will have originated from points as far as 76 sextillion (76,000,000,000,000,000,000,000) miles away. It will have taken those waves some 13 billion years to arrive on earth, meaning they left their source about a million years after the big bang, and roughly nine to ten billion years before Earth even formed.

4 " Woodrow Wilson “Woody” Guthrie (1912–67) was born in Okemah, a small town in Oklahoma, and was named for the Democratic presidential candidate by his father, a businessman involved in real estate, newspaper writing, and local and state politics. "
5 " Washington used this sword after 1777. On its scabbard is etched “J Bailey, Fish Kill,” as the sword was remounted with a new hilt and silver cross guard in Fishkill, New York, by John Bailey, an immigrant cutler from Sheffield, England. It was used by Washington as his battle sword when commanding the Continental Army for much of the Revolutionary War. "
