      What is Neuromarketing?

      Neuromarketing is a field of marketing that involves studying the way people react to marketing techniques and adjusting those techniques to maximize sales and inform the public about a specific product, idea, or campaign. Neuromarketing includes the use of biometric sensors, social studies, and subliminal messaging. While neuromarketing is a relatively new technique, it has

    • What Are the Steps of the Rock Cycle?

      What Are the Steps of the Rock Cycle?

      The rock cycle is an essential geological model that depicts the unique changes that rock undergoes during a set time period. The three major rock types are sedimentary, metamorphic and igneous. Rocks are formed and obliterated in cycles. The rock cycle depicts the formation, destruction and restoration of rocks. These changes take place due to

    • What Are Pennies Made Of?

      What Are Pennies Made Of?

      Before 1982, the penny was made of copper which is why they, unlike most other coins, don't look silver. However, after 1982, the U.S. government realized that it was too expensive to make a penny–more than the penny was worth in money–so they decided, instead, to make it with a mixture of two different metals.

    • How Does an Ultrasonic Nebulizer Work?

      How Does an Ultrasonic Nebulizer Work?

      An ultrasonic nebulizer is a small, portable device that uses ultrasonic sound waves to break liquid particles down into a fog so that they can be inhaled easily. Patients who have asthma, COPD, pneumonia, chronic bronchitis, emphysema, or other chronic conditions, most often use them for medicinal purposes. While other devices can deliver the medicine

    • How Do Quasars Form?

      How Do Quasars Form?

      Quasars are a phenomena that, to this day, continue to baffle and confuse astronomers. There are different theories. One is that a quasar is formed from a super, massive black hole. Another theory is that a quasar is actually a baby galaxy and is at the earliest stages of development. However, since no one really

    • Speedometer Calibration

      Speedometer Calibration

      One of the most prominent gauges on an automobile’s dashboard is the speedometer. Its primary function is to give a visual indication of a vehicle’s speed in miles or kilometers (or both) per hour. Since the majority of these devices are still analog, they may require speedometer calibration when new tires are installed, major automotive

    • How a Volcano Erupts

      How a Volcano Erupts

      A volcano is any opening in the Earth’s surface that allows molten rock and volcanic gases to escape from far below the Earth’s surface. Although many volcanoes are mountainous in shape, a volcano can exist in nearly any form, including volcanic vents on the ocean floor, ice volcanoes, which have been found on a variety

    • 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

    • Boltzmann Constant

      Boltzmann Constant

      The Boltzmann Constant (Boltzmann’s Constant) is a fundamental physics constant that plays a pivotal role in almost every single statistical formulation in both quantum and classical physics. It is named after Austrian physicist, Ludwig Boltzmann (1844 – 1906), who made significant contributions to the foundation and development of a particular branch of theoretical physics known

    • How Do Quartz Watches Work?

      How Do Quartz Watches Work?

      A quartz watch is one that uses a tiny, paper thin piece of quartz to measure the time. An electrical pulse is sent into the quartz which causes it to vibrate. This vibrating is then picked up by the watch and it is measured. Then, the vibrating pulse is sent to the hand which turns
