Uranus at opposition is just barely visible to the naked eye and was undoubtedly seen by the ancients. But it moves very slowly, about four degrees per year, so that its motion is not readily apparent. With no special reason to watch this particular dim star over the course of several months, none of the ancient records identify it as a planet.
Pulse (or the count of arterial pulse per minute) is equivalent to measuring the heart rate. The heart rate can also be measured by listening to the heart beat directly (auscultation), traditionally using a stethoscope and counting it for a minute. The radial pulse is commonly measured using three fingers.
Your pulse is a measure of how many times per minute your heart beats. You can find your pulse by lightly pressing on your skin anywhere there's a large artery, such as the side of your neck or the inside of your wrist just below your thumb. When you're resting your heart probably beats about 60 to 100 times per minute.
