This video is a formal analysis of Pieter Bruegel's painting The Procession to Calvary.

STONEHENGE THE SUN IS REVEALED FROM BEHIND THE SCUDDING CLOUDS AND BATHES THE LICHEN COVERED STONES. THEY WERE DRAGGED HERE FROM THE MOUNTAINS OF WALES AND THE MARKS OF THE ANCIENT STONE CUTTERS ARE CLEARLY SEEN ESPECIALLY ON SOME THAT...

One of the most insidious problems project managers face is scope creep. Scoping is hard - perhaps the hardest discipline within project management. So knowing how to prevent scope creep will be critical...

In this video, you will explore class variables in Python OOP, how they differ from instance variables, and their use cases in creating shared attributes among class instances.

Vincent ventures to the Canadian north and Haute-Savoie to build and sleep in an igloo, testing if it can really keep you warm. With expert guidance, he learns about the insulating properties of snow and the construction process of...

Earth's orbit is constantly evolving through Milankovitch Cycles.

Dr. Boyd details his experience seeing a rare Puerto Rican Amazon (Parrot) sighting in Puerto Rico.

Pi (π) is a fascinating number with many applications in mathematics, physics, and engineering. Its infinite decimal representation is a reminder of its fundamental nature in the universe. Mathematician Johann Lambert proved that pi is...

The tangential velocity is measured at any point tangent to a rotating wheel. Thus, angular velocity, w, is related to tangential velocity, Vt, through the formula: Vt = wr. Here, r is the radius of the wheel. Tangential velocity is the...

Resonance is a way of describing delocalized electrons within certain molecules where a single Lewis formula cannot express the bonding. To understand resonance in chemistry, you need to first understand covalent bonds, sigma and pi...

No, a straight line isn't always the shortest distance between two points. The shortest distance depends on the geometry of the object or surface in question. While a straight line is the shortest distance between two points on a flat...

The debate around how many holes a straw has, is one of fascinating debates to be a part of! There are those who say there are two holes while some feel there is only one whole. Some have gone so far as to claim that a straw has zero...

A circle is 360 degrees But have you ever thought why is a circle not a simpler number, like 10 degrees or 100 degrees? As it turns out 360 is actually a very good number. From a purely mathematical standpoint, a number like 10 or 100...

A rainbow is not actually shaped like a semicircle or an arc; that is simply the shape that we see. In fact, a rainbow is a circle, but we can’t see the full shape because the horizon cuts off the lower half. However, if you were...

Planetary orbits are elliptical because gravitational interaction over time changes the delicate balance of mass, velocity and distance from the star which otherwise keeps planetary orbit circular. For a very long time, from Ptolemy to...
