**getting ready for school in the morning:**sits on my bed without a shirt on for 10 minutes thinking about how much I hate school

Astronaut Chris Hadfield recently wrote a post for

Mashableabout what it’s like to orbit the earth.In just 92 minutes we go all the way around, incredulously gazing on place after place, barely known and only dreamed of. The colors and textures pour underneath, a refilling kaleidoscope of delight. Over the months in space that followed, I took thousands of photos to capture and remember it. My book

You Are Hereis the best of those photos — my guided tour of our planet, as if we were floating and looking out the spaceship window together. Here are a few.[

DM: You changed alignment

again? Make up your mind already!Player 2: I know, I know, I keep waffling on my decisions. I’m, uh, mostly lawful-neutral. I think.

DM: I’m going to mark you down as waffle-neutral.

Geometrical Constructions[part 1] - [part 2] - [part 3]I think “Geometrical Constructions” is a handy reference about geometry.

In figure 25: Draw a circle that will tangent two lines and go through a given point C on the line F C, which bisects the angle of the lines.Through C draw AB at right angles to C F; bisect the angles D A B and E B A, and the crossing on C F is the center of the required circle.

Or In figure 28: To plot out a circle arc without recourse to its center, but its chord A B and height h being given.

With the chord as radius, and A and B as centers, draw the dotted circle ares A C and B D. Through the point 0 draw the lines A O o and B O o, Make the arcs C o = A o and D o = B o. Divide these arcs into any desired number of equal parts, and number them as shown on the illustration. Join A and B with the divisions, and the crossings of equal numbers are points in the circle arc.
