I will be taking the step 1 boards this spring and am wondering if anyone knows of particularly good study aids/books. I heard that there are some Goljan DVDs--where can one get them? Also, how exactly is the USMLE scored? What is a solid number for top residencies?

Today is October 6, 2006, and the moon glows brighter today then I could ever remember. What could be the reason for this? It seems to shine a pure white of light as if it was a spot light. Could this have something to do with the sun or the aliments of the planets?

I had a 90 avg coming out of high school, I study at least 4-5 hours a day (full days sometimes), yet I still am finding engineering to be depressing because I am not doing that good. It feels like I'm always falling behind, and I am jealous of those who do better than me. I fear this jealousy is clouding my judgement. What should I do, how should I think?.. and dropping engineering is not an option for me.

We know that plants gather immense ammounts of energy from the sun through photosynthesis.

How does their energy absorption capacity compare to modern solar cells, and can we someday engineer algae or other simple plants to collect energy for us?

If you agree with the ennumerated statement, go to the next. If you agree with every statement it seems that I've proven perpetual motion.

1. Consider two unsupported weights of equal mass connected by cord. The cord runs over a pulley. They balance, no? There is no movement.

2. Now one weight rolls on a horizontal track leading up to the pulley. The free falling weight should be sufficient to move it the full length of the track, unless there is an obstruction to either of the weights. My experimentation confirms this.

3. Now the tracked weight runs up at a 45 degree angle, leading to the pulley. Since the tracked weight is partially supported by the track, the falling weight still should be sufficient to move it.

4. Now both weights are set on arced tracks fixed on top of see-saws. When one weight is pushed to the opposite end of its see-saw, a cord attached to the end of the see-saw running over a pulley should be sufficent to pull another tracked weight. Horiz --> Vert.
