When all grains in a rock are large and easy to see, the rock is described as coarse-grained.
Robert Brown called the moving motion he saw brownian motion
The term used to describe the size and organization of the materials that comprise a rock is 'texture'.
grains
Granite does not have rounded grains but contains interlocking grains. An example of a rock with rounded grains is a sandstone.
Assuming this is the standard tale of a doubling of the grains of rice each day for thirty days: Day 1 = 1 grain, Day 2 = 2 grains, Day 3 = 4 grains, Day 4 = 8 grains, Day 5 = 16 grains, Day 6 = 32 grains, Day 7 = 64 grains, Day 8 = 128 grains, Day 9 = 256 grains, Day 10 = 512 grains, Day 11 = 1,024 grains, Day 12 = 2,048 grains, Day 13 = 4,096 grains, Day 14 = 8,192 grains, Day 15 = 16,384 grains, Day 16 = 32,768 grains, Day 17 = 65,536 grains, Day 18 = 131,072 grains, Day 19 = 262,144 grains, Day 20 = 524,288 grains, Day 21 = 1,048,576 grains, Day 22 = 2,097,152 grains, Day 23 = 4,194,304 grains, Day 24 = 8,388,608 grains, Day 25 = 16,777,216 grains, Day 26 = 33,554,432 grains, Day 27 = 67,108,864 grains, Day 28 = 134,217,728 grains, Day 29 = 268,435,456 grains, Day 30 = 536,870,912 grains. Adding them all together = 805,306,368 grains (805 million, 306 thousand, 368 grains) in total. At 29,000 grains of long-grain white rice per pound, she received 27,769 pounds of rice in total (approximately).
