HEARTS ON HIGH: It's Valentine's Day, so hearts abound! Above is a photo of the aptly named Heart Nebula. It's about 7500 light years away from Earth, in the Perseus Arm of the Galaxy in constellation Cassiopeia. There are lots of lovely photos of this nebula out there - just Google 'heart nebula images' if you care to see more.
Here's a heart seen from on high. It's a photo NASA astronaut Karen Nyberg took during her most recent stint on the International Space Station.

Even though Mars is the god of War, there are hearts on the Red Planet. Here are several images from JPL to prove that point.
While many people receive or give chocolate as gifts today, on board the ISS, they're flushing 'em down the toilet - all in the name of science, of course. Check out this story:

TESTED: "Stress! Stress! Stress! Stress! Oh my god, stress!" Annabelle declared just before launching the timed genetics and evolution midterm test this afternoon.
We've spent several hours studying for the test, and a lot is on the line, as it accounts for about half of our grade in the course.
We each had 90 minutes to take the test from the time you log in. To say it didn't go well would be an understatement.
Almost immediately, my computer crashed, HARD. It took forever to reboot. Calculators wouldn't work. Dogs barked. There were multiple questions we've never seen before in any form. The printer crashed from its shelf to the hardwood floor. Annabelle became hysterical. CJ turned into a zombie.
Such fun! And that was only the first half of the test.
Afterward, we reviewed what went very, VERY badly, and what went well (I think our math was sound, and we each did get every question answered. I pointed out to them the second half of the test almost HAS to go better, but that we're not doing it today. Enough is enough!
Your test experiences matched your expectations - as they usually do. You may have been OOD as some in my Astronomy class refer to themselves. (OOD is Out of Our Depth. Happens often in Coursera classes because there are no prerequisites to get in). I congratulate all of you for taking the exams instead of auditing the class. By the way, I'll bet your experience was the norm.
