An old brick has a natural cavity on one side, providing a cool daytime slug hiding place. Look under any you have around the garden and dispose of the slugs found sheltering. Purposely position a few to create slug shelters, and check daily. A brick also makes a handy squishing implement.
Q Angle of the Knee. The Q angle of the knee is a measurement of the angle between the quadriceps muscles and the patella tendon and provides useful information about the alignment of the knee joint.
Q has a number of uses in physics... It could be... The first moment of area about a neutral axis The quality factor of an oscillator An arbitrary coordinate Electric charge Heat The position operator in quantum mechanics (in some cases) Those are a few, if I've forgotten any my apologies.
