Find Direction Between 2 Points: A & B

Thread starter RAHIL008
Start date May 20, 2011

AI Thread Summary

To calculate the direction from point A to point B using their latitudes and longitudes, the spherical sine law and spherical cosine law can be applied. These mathematical principles help in determining the angular distance and bearing between the two points on the Earth's surface. For detailed formulas and explanations, resources such as Wikipedia on spherical trigonometry can be useful. Understanding these laws is essential for accurate navigation and geolocation tasks. Accurate calculations ensure effective direction finding between any two geographic coordinates.

Hi RAHIL008!

Use the spherical sine law and the spherical cosine law …

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.
