""I want you to share my excitement at the discoveries, past and present, which have revolutionized the way we think. From the Big Bang to black holes, from dark matter to a possible Big Crunch, our image of the universe today is full of strange sounding ideas, and remarkable truths. The story of how we arrived at this picture is the story of learning to understand what we see." "

"A "How it's made" video showing how they make something that makes other things. Specifically, a laser cutting machine. The coolest thing we didn't know before seeing the video is that a laser beam must be the appropriate shape in order to cut optimally, just like a router bit or a kitchen knife designed for a specific task.

"Build a bridge and test your construction skills. Help your workers collect items located on the other side of the valley. Instructions Build a bridge using the components and the budget available. Once it is done, click "Test your bridge" to see if it will sustain the weight of the workers and the cargo. Your workers will use it to get items located at the other side of valley, and bring them back to the shop. Your goal is to collect all items in level."

"That is the most beautiful film I have ever seen. And to think...these are the Noble Creatures that Monsanto and other giant pesticide makers are destroying with neonicotinoid pesticides with the full approval of the Environmental Protection Agency. GMO crops sprayed with glyphosate and other deadly pesticides are killing these beautiful bees, bats, hummingbirds and so many other insects. Can't we just figure out a Monsantocide and save these beauties?"

GLOBE at Night is a worldwide, hands-on science and education program for primary and secondary schools. The GLOBE at Night project encourages citizen-scientists worldwide to record the brightness of the night sky. During four select sets of dates, children and adults match the appearance of a constellation (Orion or Leo in the northern hemisphere, and Orion and Crux in the southern hemisphere) with seven star charts of progressively fainter stars. The map is located at http://www.globeatnight.org. Participants then submit their choice of star chart online with their date, time and location to help create a light-pollution map worldwide.

"On April 13, 1970, disaster strikes 200,000 miles from Earth when oxygen tank No. 2 blows up on Apollo 13, the third manned lunar landing mission. Astronauts James A. Lovell, John L. Swigert, and Fred W. Haise had left Earth two days before for the Fra Mauro highlands of the moon but were forced to turn their attention to simply making it home alive. Mission commander Lovell reported to mission control on Earth: "Houston, we've had a problem here," and it was discovered that the normal supply of oxygen, electricity, light, and water had been disrupted. "

"Saturday, April 11, 1970 at 13:13 CST. At five and a half minutes after liftoff, Swigert, Haise, and Lovell felt a little vibration. Then the center engine of the S-II stage shut down two minutes early. This caused the remaining four engines to burn 34 seconds longer than planned, and the S-IVB third stage had to burn nine seconds longer to put Apollo 13 in orbit. "
