A laser printer is one of the most common types of consumer electronic device used for recreating digital images to a variety of media, particularly papers, substrates, and other compatible surfaces. It is specifically a non-impact printer that works by firing a laser beam on a negatively charged, mechanical, and photosensitive cylinder called a drum. […]

Inkjet Printer: Advantages and Disadvantages
An inkjet printer recreates digital images by accurately pushing or depositing droplets of inks onto a paper or substrates and other printable surfaces. As one of the most common types of printers in the market, its availability ranges from inexpensive consumer units to more expensive commercial models. Four major companies manufacture and market inkjet printers […]
Why Is Venus Hotter Than Mercury?
Mercury is the nearest planet to the Sun. It orbits at an average distance of 58 million kilometers. However, despite this proximity, Venus remains the hottest planet in the Solar System. It is about twice as far from the Sun of average as Mercury. Specifically, it orbits at an average distance of 108 million kilometers. […]
Buoyancy Explained: The Archimedes’ Principle
Greek mathematician, physicist, and engineer Archimedes of Syracuse suggested in his 250 BCE work “On Floating Bodies,” that any object, whether totally or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object. The infamous assertion made by the ancient Greek polymath is […]
Glenn Borchardt: 10 Assumptions of Science
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 […]
