I was employed by the Federal Highway Administration from the mid 70s to 2008. I did work in many subject areas over this time but am probably known most for managing one of the big discretionary programs, for creating Interstate designation content and for research and management in the area of highway economic development.
I did other things over the years: e.g., taught people in the FHWA how to play the card game called "schafskoft", raised a family, served in the US Navy reserves, served on the board of various civic and religious organizations.
My daughter lives in Israel and the rest of the family have visited there many times.
Tonight we got some images of Lev studying Tractate Makkot. Lev might use them in the marketing phase of the build out of his for profit learning and doing yishiva. This would assist in the vertical scaling of the enterprise (although Lev admits that he doesn't know what words and phrases like "build out", "marketing phase" or "vertical scaling of the enterprise" mean.
The first image is from an interior page 22b which is part of perek III of Tractate Makkot. It shows a type of whip made from the hide of a donkey and the hide of a calf. It also has some commentary by RAMbam.
The second image is of Lev examining the back of the volume. As you can see, the volume includes both Makkos and Shavuot (vows).
The third image shows the same page as the first image but from a greater distance so you can see Lev studying it.
The fourth image is a smaller version of the first image. Somehow it popped up on the post and it is hard to get rid of it.
