In ancient times, the most powerful and influential cities in the world were located primarily in Asia, Africa, and the Middle East. Places like Alexandria, Jericho, and Carthage once were thought to be as influential or powerful as...

It seems counterintuitive, but ESA's newest space telescope, CHEOPS, is designed to take blurry images of stars. But this helps astronomers to understand more about orbiting exoplanets than a clear image would. Here's why!

A post on Medium in May 2016 attempted to tackle a seemingly unanswerable question: what's the weirdest town in America? To do this, Lyman Stone used 20 different variables, including what percentage of each city's population was...

Tempered glass is stronger than regular glass and can withstand higher temperatures. It is also manufactured in a way that causes it to break into smaller pieces, which is safer than regular glass shattering into large shards. Unlike...

The term drone is actually taken straight from the sci-fi world. Drones are used for many reasons for filming, military surveillance, and recreational activities. Drones fall under the intersection of aerospace, robotics, and...

Spacetime, as a concept, is related to a space that consists of 4 dimensions instead of the regular 3-dimensional space. As early as 1905, Einstein proposed a now widely popular theory that the speed of light is independent of the motion...

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...

Dark matter is an invisible matter that occupies more than half of the space of the observable universe but cannot be detected directly as it doesn’t interact with electromagnetic radiation, like visible light and gamma rays. One of the...

Carrying a pole helps the walker increase their rotational inertia, which aids in maintaining stability while walking over the narrow rope. The pole also adds more weight below the center of gravity of the walker, which is another bonus...

A frequent reason for a healthy cat to refuse to eat from a bowl with plenty of food left behind is that the cat may have whisker fatigue. Some cats experience whisker fatigue when their highly sensitive whiskers are constantly being...

The clarity of ice cubes is determined by the temperature of the water used to make them. Warmer water contains more impurities, which are released when the water is cooled and frozen. Ice cubes made from distilled or boiled water are...

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...

Discover how urban expansion affects local agriculture through the eyes of a Clark County farmer facing the encroachment of urban growth boundaries. Learn about the complexities of investing in farming operations amidst uncertainties of...

From ancient civilizations to modern breakthroughs, learn about the nine most important cosmic discoveries that changed the way we look at our Sun, Moon and beyond. Learn how Copernicus challenged the status quo, Kepler unveiled the...

Unreachable by man, scientists have developed a complex experiment to demonstrate the heat and pressure at the centre of the Earth. Earth Science - Geology - Learning Points. The Earth's core is a dense ball of iron and nickel. To...

The answer is not as straight-forward as it might seem, because all triangles have more than one centre! How many centres does a triangle have, and how do you find them? Maths - Shape A Twig Math Film. Reinforce and extend the learning...

Water is added to dry and bent matchsticks to let us see capillary action at work. The wood absorbs the water causing the matchsticks to straighten. Biology - Plants - Learning Points. Water is a polar molecule because the electrons are...

Scientists believe there is a supermassive black hole 26,000 light years away at the centre of our Galaxy. But how do they know, when they can't see it? Physics - Universe - Learning Points. Black holes are formed when massive stars...

Learn about the history of the famous cathedral in Paris, the Notre-Dame and the efforts to rebuilt it after the recent fire damage.

Newman projections are a powerful tool for visualizing the three-dimensional conformations of cycloalkanes. By looking down the axis of a particular bond, this projection allows chemists to depict the spatial arrangement of atoms and...

Symmetry and optical activity are intricately linked in organic molecules. A molecule is optically active if it can rotate the plane of polarized light. Optical activity arises from the molecule’s lack of symmetry—specifically, its...
