    • What is Rhodium Plating?

      What is Rhodium Plating?

      Rhodium plating is a type of metal plating that prevents an object from being scratched or tarnished and improves the object’s color quality. Rhodium is a precious metal that is five to twenty-five times as expensive as gold and is used for plating jewelry and other objects in order to make them brighter, smoother, and

    • Dielectric Constant

      Dielectric Constant

      A dielectric constant measures the extent that a material concentrates electrostatic flux and is also known as the relative static permittivity, static dielectric constant, and relative dielectric constant. It is essential when determining if a substance can be used in a capacitor or various chemistry and physics applications. A material’s dielectric constant value must be

    • Seebeck Effect

      Seebeck Effect

      The Seebeck Effect was first discovered in 1821. It describes the thermoelectric phenomenon that results when the temperature differences between dissimilar metals in a circuit are converted into electric current. This is one of three similar processes that relate to conductivity, temperature, and thermoelectricity that was discovered in the 1800s. The Thomson Effect was first

    • What is Photolithography?

      What is Photolithography?

      Photolithography is the process of making integrated circuits through optical erosion. Rather than directly cutting into an integrated circuit, photolithography is used due to its ability to perform more precise incisions. Photolithography is a highly complex technique and requires both an extremely clean substrate surface and ideal temperature conditions. It can only be used to

    • Who Invented Electricity?

      Who Invented Electricity?

      No one person invented electricity, but its modern day use is the result of the work of inventors, scientists, and researchers who toiled over the subject for millennia. In order to fully understand electricity in our modern world, one has to first understand the pioneers who date back to as early as the ancient Greeks,

    • The Venturi Effect

      The Venturi Effect

      The Venturi effect is the phenomenon that occurs when a fluid that is flowing through a pipe is forced through a narrow section, resulting in a pressure decrease and a velocity increase. The effect is mathematically described through the Bernoulli equation and can be observed in both nature and industry. Many industry applications rely on

    • What Causes Optical Illusions?

      What Causes Optical Illusions?

      In simple terms, an optical illusion is caused by the structure of both the eye and brain and how they work together. Because of the anatomical make up of the eye and the complexity of the way images of transmitted from the eye to the brain, optical illusions are not as rare as one might

    • Total Harmonic Distortion

      Total Harmonic Distortion

      Total Harmonic Distortion (THD) is a measured difference in audio levels between the input audio signal’s harmonics and the harmonics of the output audio signal of an amplifier or other audio device. Output Distortion Level As the signal passes through an amplifier it is always somewhat distorted at its output. The waveform at the input

    • What is Luminous Flux?

      What is Luminous Flux?

      Luminous flux (luminous power) is the measurement of the (perceived) power of light. It is adjusted to take the human eye’s sensitivity to the different wavelengths of light into account. Luminous flux differs from radiant flux in this manner, since radiant flux is a measurement of the total power of light emitted independent of wavelength.

    • 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
