Practical Astronomy Using Calculator
Over time, astronomers have concerned themselves with measurements. Believe it or not, astronomy can be tabulated by using a calculator.
But practical astronomy with calculators isn’t an easy subject. Most people will have a hard time dealing with this primarily because it tackles mathematical and statistical possibilities.
Take for example: equatorial coordinate conversions. These are the astronomical conversions. Good thing there are calculators online that will help the non-mathematical interested astronomer.
Then there’s taking inverse tan and local civil time. These are factors that contribute to astronomy. Local civil time is side by side with terrestrial dynamic time. The turn of the universe is meticulously studied by astronomers because this results to incidences in the solar system.
The equatorial horizontal parallax and the geocentric parallax rely heavily on the orbit of the planet earth. For the mere layman, this is deemed ‘”revolution” and “rotation” but for the astronomer, local sidereal time and inverse cause affect the solar elongation of each turn of the planet and its gravitational pull.
The hourly motions are attributed to the elliptic longitude and these decimal hourse depend entirely on the placement of the planet on the correct quadrant. With each elliptic latitude, the sin is inversed and the geocentric longitude results to ephemeris time.
At this point, you will realize that there are mathematical terms in this kind of astronomy. That being the case, mathematical experts know which buttons to press in a calculator to come up with the calculation that they are looking for.
Astronomy is closely related to mathematics. If you’ve seen the Jodie Foster and Matthew McConaughey 1997 movie “Gattaca”, you see the scientists there pittering and pattering away on their keyboards as if they were calculators. This only justifies the notion that the calculations astronomers need (the distance of one celestial object to another, the longevity of the particular planet to travel around its orbit, the number of days before a meteor hits planet earth – which is common to most American films), all these are achieved using mathematics.
For more information regarding the matter, there are books available discussing astronomy side by side with mathematics. A number of which also have illustrations that can entice the interested astronomer to know more of the science despite its mathematical demands.
Who knows? This maybe the case of interest prevailing over ability? You may not have the mathematical abilities for it but your interest in astronomy makes you come up with the calculations nonetheless.
