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.
The heart rate is the number of heartbeats in one minute. The pulse is the physical measurement used to calculate the heartbeat found in different parts of the body-apical, femoral, carotid, radial to name a few. The actual pulse is the distension of the arterial wall with each heartbeat.
