What I wanted to build was an engineered double sided stone faced wall, backed with timber on each side, and the space between back filled with stone ...nd dirt. And, I wanted that wall to be twenty feet tall and close to two miles long. Let me put that into perspective. Stone blocks a couple of feet on a side weigh about 150 lbs per cubic foot, so each stone would weigh about half a ton each. Each wagon we used would carry between four to six stones per load. A mile of stone facing twenty feet. . pleasant. Not even the AIs can explain why this is.Due to the small size of my fast courier, I was able to safely drop into the system near the moon. Entering hyper my small footprint meant that I could jump from closer to either a planetary body or a star than any other hyper-capable ship.Considering that I knew my itinerary for this jump had not included Earth, I figured that we'd been diverted by a hypercomm signal.My courier, with me providing the "body english", nosed up to the command.

As you know, we're looking at nano-tunneling in power semiconductors modulated by cross-discipline energy inputs."It's as much ceremony as exam, really. There were a number of pro forma questions, causing me to flip through several auxiliary presentations for answers. I do GOOD PowerPoints. I learned from mentors who sat through too many bad ones. My slides are brief and serve only to emphasize what I'm saying. I show pictures of my lab work and the graphs of the data that come.
