    • Supercavitation

      Supercavitation

      Cavitation happens when water moves at extremely high speed around an obstruction in its normal flow. This causes the water pressure around the propeller to drop, creating air bubbles which dissolve after a few moments and causing water to rush in on the empty space created previously by the bubbles then crashing against the obstruction.

    • What Causes Earthquakes?

      What Causes Earthquakes?

      An earthquake is caused when two blocks or plates of the Earth slip past each other in the lateral, vertical, or a combination of directions in a sudden manner. Due to the large pressures that develop between the Earth’s plates along fault lines at the Earth’s surface, one of the bodies will eventually give way.

    • What is Flocculation?

      What is Flocculation?

      Flocculation is when microscopic particles bind together to form larger particles in liquids. It occurs naturally or artificially in water as well as other solutions. Flocculation is used in applications such as water purification, sewage treatment, cheese production, and brewing. It is also used in surface and physical chemistry, biology, and civil engineering. The term

    • How Do Oil Rigs Work?

      How Do Oil Rigs Work?

      As recent events concerning oil spills in multiple locations have flooded the news, many people are wondering how oil drilling works and why something like an oil spill can happen. This article will attempt to answer these questions by explaining how the various processes of oil drilling work. What is an Oil Rig An oil

    • What Causes Copper to Turn Green?

      What Causes Copper to Turn Green?

      Copper turns green because of a process known as oxidation which is the removal of electrons from the substance. Specifically, copper turns green because of something known as copper carbonate. This is the substance that is found on top of copper–whether they be copper pipes, pennies, statues or anything else. So, the cause of copper

    • Why is Geography Important?

      Why is Geography Important?

      While many of us labored to learn geography in school, we always wondered why it mattered. Here are some reasons why a sound understanding of geography is more important today than ever before. Politics We live in a world that is shaped by the political climate in various locations around the globe. In order to

    • What is an Ultrasonic Fogger?

      What is an Ultrasonic Fogger?

      An ultrasonic fogger is a device that uses ultrasonic sound waves to break water into millions of individual water droplets that are then sprayed into the air as a thick fog. Ultrasonic foggers are most often used for Halloween decorations as a dry ice replacement. The fog that an ultrasonic fogger produces is not created

    • Magnetic Levitation

      Magnetic Levitation

      Magnets are mainly characterized for having poles: if you put together poles of the same charge they repel and if you put together charges of different pole, they attract. A body will be under Magnetic Levitation when it floats due to that special repelling quality of the magnets, i.e. when the force generated by the

    • How Do Neurons Work?

      How Do Neurons Work?

      The neuron is the cell responsible for the transfer of information and electrical impulses around the body. Neurons work by transferring electrical charges from neuron to neuron to get from one point to another. All data, therefore, is transferred in this electrical fashion which is why computer science has become such an important tool in

    • Weather Modification Technology

      Weather Modification Technology

      Weather modification refers to willful manipulation of the climate or local weather. Research done in this field goes back to as far as the early 1940s when the US military experimented with cloud seeding to stimulate rain. Today, private corporations have joined the weather modification research effort to protect people, cities and assets from the
