During the 1950s and 60s, engineers and scientists sought ways to use nuclear weapons for major construction projects such as harbors, roads and even alternative routes for the Panama Canal.

The troubled spacecraft is scheduled to undock on Friday for a trip back to Earth while two NASA astronauts will stay in orbit.
I've been dealing with this for months. I've received yet another drawing from a company calling "Diameters on a common axis/center to be 0.XX" TIR U.O.I. "
Total Runout requires a Datum. Your "common axis" is not a datum and can not referenced. It's driving me mad. Like, where did everyone get this notion that it's acceptable? It'd be one thing if it was just one or two drawings, but I'm into the dozens at this point. It's getting to the point that I'm starting to question if I'm either the one in the wrong or everyone has some sort of mass psychosis.
Am I in the wrong here?

What aspect are you most passionate about and why ?
Hey folks, I'm working on a project involving the design of a heat exchanger, and I've hit a bit of a wall. I'm trying to optimize the fin design for maximum thermal efficiency while keeping the pressure drop within acceptable limits. I know the general principles, but I'm struggling with the specifics of selecting the right fin geometry and material.
Any tips or resources you could recommend for tackling this?
Appreciate any advice from those who've been down this road before!
