Junius Stinney was the youngest person in America to be executed on death row in 1944 at age 14. He was quickly accused by the (white police) of ‘killing’ two little (white girls) with lack of evidence. His conviction and sentencing opened and closed in one day. There were no witnesses called and there was no transcript of the trial details and black people were not allowed inside the courtroom during that time.
[I always repost this because i don’t want anyone to forget about him!]

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.
