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.
When taking your pulse: 1  Using the first and second fingertips, press firmly but gently on the arteries until you feel a pulse. 2  Begin counting the pulse when the clock's second hand is on the 12. 3  Count your pulse for 60 seconds (or for 15 seconds and then multiply by 4 to calculate beats per minute).
