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.
Calculate your pulse. Note or remember how many heartbeats you counted. Your pulse rate is measured in beats per minute. For example, if you counted 41 for 30 seconds, double it to get 82 beats per minute. If you counted for 10 seconds, multiply the beats counted by 6, and if you counted for 15 seconds, multiply by 4.
