For as long as we have had mathematics, forward-thinking scholars like Grienberger have tried to imagine the far limits of engineering, even if the technology of the time was lacking. Over the centuries, they have dreamt of machines to lift the world, transform the surface of the Earth, or...
To test that sunPosition() works correctly, I've compared its results with those calculated by the National Oceanic and Atmospheric Administration's Solar Calculator. In both cases, sun positions were calculated for midday (12:00 PM) on the southern summer solstice (December 22nd), 2012. ...
Finding longitude by lunar distance observations with the formerly lengthy data reduction is simplified with a pocket calculator method described. Such calculators are coming into use for small boat navigation. In contrast to the recent lunar altitude methods using LOP constructions, which attracted ...
distance = DistanceCalculator.distance( position.getLatitude(), position.getLongitude(), last.getLatitude(), last.getLongitude()); distance = BigDecimal.valueOf(distance).setScale(2, RoundingMode.HALF_EVEN).doubleValue(); }if(filter && last.getValid() && last.getLatitude() !=0&& last.getLo...
($ipswich,$london);// You can then compute the distance...$distance=$distanceCalculator->get();// you can also chain these methods together eg. $distanceCalculator->get()->asMiles();// We can now output the miles using the asMiles() method, you can also calculate and use as...
