A solid-state drive or SSD is one of the two major types of data storage device alongside a hard disk drive or HDD. Both HDDs and SSDs are more popular because of their reasonable manufacturing cost and better storage capacity. However, in choosing an SSD over an HDD, it is important to take note of […]

OLED vs. IPS LCD: Which One is Better?
Two display technologies currently dominate the consumer electronics market. These are organic light-emitting diode or OLED displays and in-plane switching liquid crystal display or IPS LCD. As a backgrounder, an OLED uses organic compounds that emit light in response to an electric current. On the other hand, an IPS is a specific type of LCD […]
TN LCD: The Pros and Cons
Twisted nematic or TN LCD is a type of thin-film transistor liquid crystal display or TFT-LCD that is commonly used in an array of consumer electronic devices such as digital watches and calculators, as well as computer monitors and mobile phones. Note that it is the most common type of LCD technology because of its […]
IPS LCD: The Pros and Cons
In-plane switching or IPS LCD is a type of LCD technology first introduced in the mid-1990s and became popular in the mass market in the mid-2000s. Note that its development marked an improvement in tested nematic LCD and its further utilization rivals modern display techs such as OLED technology, Quantum Dots, and QLED technology. The […]
OLED Display: The Pros and Cons
The Pros of OLED Display Technology Below are the advantages and applications of this display technology: 1. One of the strengths of an organic light-emitting diode or OLED display technology over other technologies such as LED and LCD is that it consumes less power. Each diode in an OLED panel emits light. The entire panel […]
The Difference Between DNA and RNA
Both deoxyribonucleic acid or DNA and ribonucleic acid or RNA are macromolecules called nucleic acids that play a role in the coding, decoding, regulation, and expression of genes. Along with other macromolecules such as carbohydrates, lipids, and proteins, DNA and RNA are essential for all known forms of life. Another similarity between DNA and RNA […]
Quantum Dots Explained
Quantum dots or QDs are nanocrystalline semiconducting materials that have optical and electrical properties. Their sizes range from two to fifty nanometers. Most types of quantum dots have either photoluminescent or electroluminescent properties. In other words, they emit light when excited by light or electricity. What Are Quantum Dots? What Are Their Properties? It is […]
Special Relativity vs. General Relativity: The Difference
Renowned theoretical physicist Albert Einstein first introduced the Special Relativity Theory in the paper “On The Electrodynamics of Moving Parties” he published in 1905. In 1915, he also introduced another theory called the General Relativity Theory. What Is The Difference Between the Special Relativity and General Relativity? Note that both theories were derived from the […]
Newtonian Gravity vs. the Geometric Gravity of Einstein
There have been several theories postulated and formulated to define and explain the natural phenomenon now known as gravity. Two of these is the Law of Universal Gravitation introduced by Sir Isaac Newton in 1687 and the General Relativity Theory developed by Albert Einstein between 1907 and 1915. Note that Newton and Einstein had different […]
Why Is The Sky Blue: The Scientific Reason
The sky is not blue because it reflects the ocean. It does not work that way. If that is the case, then it does not explain why it remains blue when seen from a landlocked area within a vast landmass. Nonetheless, there is a simple scientific reason behind the color of the sky. The Scientific […]
