[PSA] Basic principles of outfitting your ship for laser ...

Mining lasers should be class 2 (medium) if you have appropriate hardpoints, because medium lasers have better energy-per-fragment ratio than class 1 (small). One medium mining laser consumes 3 megawatts per second (MW/s). Ideally, you should have this amount supplied by re-charge rate of your PD. Un-engineered 7A PD has the recharge rate (for weapons) of 6.1 MW/s, which is just enough to ...

Crystallization | physical process | Britannica

In mineral deposit: Pegmatite deposits. The crystallization of magma is a complex process because magma is a complex substance. Certain magmas, such as those which form granites, contain several percent water dissolved in them. When a granitic magma cools, the first minerals to crystallize tend to be anhydrous (e.g., feldspar), so… Read More

Rocks and Minerals - Geology (U.S. National Park Service)

Rocks and minerals are important for learning about earth materials, structure, and systems. Studying these natural objects incorporates an understanding of earth science, chemistry, physics, and math. The learner can walk away with an understanding of crystal geometry, the ability to visualize 3-D objects, or knowing rates of crystallization.
