Websites and apps are increasingly utilizing layered authentication to promote security and privacy online. As a backgrounder, layered authentication is an identity and access management process that uses two or more layers based on the so-called factors of authentication. A user needs to present two or more factors to grand him or her access to […]

Hard Disk Drive vs. Solid-State Drive
Hard disk drive or HDD and solid-state drive or SSD are two major types of data storage device. Take note that phonographic recording and optical discs, as well as DNA-based storage, are other types of storage mediums and technology. However, HDDs and SSDs are more popular because of their reasonable manufacturing cost and better storage […]
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 […]
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 […]
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 […]
The Pros and Cons of Augmented Reality
Augmented reality or AR involves the addition of digital elements such as graphics, audio, haptic feedback, and other sensory information to the real world, thus creating an immersive and interactive user experience. The Pros of Augmented Reality: Benefits and Applications The applications of augmented reality or AR come from the fact that it augments or […]
The Pros and Cons of Big Data
Big Data is not just a fad or a buzz terminology. The rate at which societies in developed and developing countries generate data has become a goldmine for organizations seeking to use large data sets to understand their audience and improve their performance. This article concisely discusses the pros or advantages, as well as the […]
“Good Theory” According to Stephen Hawking
What is a good theory? What are the components that make a theory good? How do renowned thinkers describe a good theory? In his book “A Brief History of Time: From the Big Bang to Black Holes” first published in 1988, widely celebrated theoretical physicist Stephen Hawking briefly discussed what he strongly deemed are the […]
