Rhodochrosite is a manganese carbonate mineral with chemical composition MnCO3. In its (rare) pure form, it is typically a rose-red color, but impure specimens can be shades of pink to pale brown. It streaks white, and its Mohs hardness varies between 3.5 and 4. Its specific gravity is between 3.5 and 3.7. It crystallizes in the trigonal system, and cleaves with rhombohedral carbonate cleavage in three directions.

If you want to be Dart Vader, you will have to deal with his everyday problems, too. That’s what Paweł Kadysz is doing with his new photo project. He aims to take a picture every day for a year – and each one of them should show the Dark Lord of the Sith tackling everyday life. Washing dishes, ironing clothes, eating breakfast – all those little things that heroes do off screen.
