In his book “The Ten Assumptions of Science: Toward a New Scientific Worldview,” Dr. Glenn Borchardt presented a set of assumptions he deemed would define 21st-century scientific philosophy. He specifically argued that assumptions and not absolutes are necessary for scientific thinking. Furthermore, he noted how critical choices among underlying assumptions either clarify or muddle scientific […]

Pros and Cons of Carbon Capture and Storage
The entire process of carbon capture and storage or CCS involves capturing carbon dioxide from point sources, processing and transporting the captured CO2 for storage, and storing or disposing them to a final location selected and in most cases, reinforced to prevent the captured CO2 from entering the atmosphere. The process has been positioned as […]
The “Agent Smith” Android Malware: Facts
Researchers from the security firm Check Point Software Technologies discovered in July 2019 a new type of malware affecting Android devices. Dubbed as Agent Smith, it works by replacing a portion of selected Android apps with its own code. The malware does not steal data from Android users or cause their devices to malfunction beyond […]
Harmful Algal Blooms: Causes and Effects
Algal bloom or algae bloom is a phenomenon characterized by a rapid increase in the population of algae in marine and freshwater ecosystems. Furthermore, this increase in population is evident from the discoloration in water from algal pigments. Nonetheless, some instances of algal blooms are harmless, while others called harmful algal blooms can present problems […]
Triada: The Android Malware
Triada is a malware that targets Android devices. It is specifically a module mobile Trojan that exists mostly in the RAM of devices and actively uses privileges to substitute system files with malicious ones. Initially, it worked by exploiting root vulnerabilities, thus gaining root access and leveraging access privileges. However, it later came preinstalled in […]
Centrifugal Force: Examples and Applications
According to Newtonian mechanics, a centrifugal force is an inertial force or an apparent force that acts on objects moving around a center or along a curved path and away from the center of the curve. Because of the force, these objects would move away from the center as they move around it or follow […]
Difference Between Absorption and Adsorption
Absorption vs. Adsorption: What is the Difference? The Basics of Absorption Absorption is a physical and chemical phenomenon in which or atoms, molecules, or ions enter or get trapped in a solid or liquid material. Unlike adsorption, the atoms, molecules, or ions are taken up by the volume and not by the surface. There are […]
Activated Carbon: Properties and Applications
An activated carbon or activated charcoal is a collective name for processed carbons with extremely porous structure and extensive surface area that allow them to effectively capture and hold materials, thus making them suitable for adsorption and chemical reaction. The processing of carbon into an activated carbon generally involves the treatment of char with heat […]
Purpose of Bird Vocalization
Research in ornithology has explored and explained the different functions of bird vocalization. Ornithologists specifically determine these functions by analyzing the acoustic structures of bird calls and bird songs, how specific species of birds produce them, how they are perceived by conspecifics, and the context in which they are produced. Difference Between Bird Calls and […]
AMOLED Display vs. PMOLED Display
AMOLED display and PMOLED display are two subtypes of OLED display technology based on an underlying principle of addressing pixels. The former stands for active matrix organic light-emitting diode or active matrix OLED while the latter corresponds to passive matrix OLED. What is the Difference Between AMOLED display and PMOLED display? What are Active Matrix […]
