I wrote the wrong equation on the last problem on the exam, but some of you did heroic things with it.

“In this presidential election season, one thing is certain: candidates will rarely — if ever — be asked what they would do to keep this nation at the forefront of science and innovation.
The truth is in the numbers. In the 1960s, the United States devoted nearly 17% of discretionary spending to research and development, reaping decades of economic growth from this sustained investment. By 2008, the figure had fallen into the single digits. This occurs at a time when the private sector has cut back on its research investment and other nations have made significant gains in their own research capabilities. China, for example, is projected to outspend the United States in research within the next decade. East Asia as a whole already does.”

Battered Earth
A new study published by NASA researchers seems to confirm that 4-4.5 billion years ago almost the entire planet was showered in an intense bombardment of giant asteroids.
This period would’ve effected the whole planet, essentially melting the surface into molten rock multiple times over, boiling any water oceans into a steam-atmosphere and dramatically altering the geological landscape.

From an excellent post by Jason Davis
From Washington, D.C., the rings would only fill a portion of the sky, but appear striking nonetheless. Here, we see them at sunrise.
From Guatemala, only 14 degrees above the equator, the rings would begin to stretch across the horizon. Their reflected light would make the moon much brighter.
From Earth’s equator, Saturn’s rings would be viewed edge-on, appearing as a thin, bright line bisecting the sky.
At the March and September equinoxes, the Sun would be positioned directly over the rings, casting a dramatic shadow at the equator.
At midnight at the Tropic of Capricorn, which sits at 23 degrees south latitude, the Earth casts a shadow over the middle of the rings, while the outer portions remain lit.
