This is one of my favorite stories. In short, one of John Burk's (@occam98) students wanted to launch a space balloon. If you want all the details, this post at Quantum Progress pretty much says it ...

If we know the length of the base of an isosceles triangle, with the two long (very long!) sides being the distance to an object, then we can solve for that distance given just one angle.

When we measure “distances” on the sky, we use angles, or angular distances, and angular sizes… The angular distance from one horizon to another is 180o The angular distance from one horizon to the ...

Observations with the Very Large Telescope Interferometer (VLTI) at the ESO Paranal Observatory (Chile) have provided the first-ever direct determination of the angular sizes of the disks of the solar ...

But when the Sun, Earth, and Moon all align to produce a total eclipse, it teach us how far astronomical distances truly are. During a lunar eclipse, the Earth's shadow falls on the Moon; showing that ...

Astronomers utilize angular measurement techniques for determining the spatial separation between celestial objects. The methodology involves measuring the angular distance or size. Angular ...

Early Astronomy Angular Size When we measure “distances” on the sky, we use angles, or angular distances, and angular sizes… The angular separation (distance) between the stars at the end of the bowl ...

When I watch the World Cup, I always think about set pieces. This is when the ball is placed at a certain spot and a team is allowed to then kick the ball (called a free direct kick). If this kick ...

Stereo or '3D' vision is an important but costly process seen in several evolutionarily distinct lineages including primates, birds and insects. Many selective advantages could have led to the ...
