Sonar (Sound Navigation and Ranging) is a technology used to detect objects underwater and measure distances using sound waves. It is widely used in navigation, submarine detection, fishing, and oceanography. 🐟🚢 Sonar works by sending sound pulses into the water and listening for echoes that bounce back from objects. The time it takes for the […]

Speciation is the evolutionary process by which populations of organisms diverge into distinct species. It is a central concept in evolutionary biology, explaining the diversity of life on Earth. Speciation occurs when genetic differences accumulate within populations, eventually leading to reproductive isolation—meaning members of one group can no longer interbreed successfully with members of another.
Sociology is a social science that focuses on society, human social behavior, patterns of social relationships, social interaction, and aspects of culture associated with everyday life. It uses various methods of empirical investigation and critical analysis to develop a body of knowledge about social order and social change. While some sociologists conduct research that may be applied directly to social policy and welfare, others focus primarily on refining the theoretical understanding of
Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula H2. It is colorless, odorless, non-toxic, and highly combustible. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus “habitat” is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which
The hydrosphere is defined as the total mass of water found on, beneath, and above the surface of a planet, minor planet, or natural satellite. Despite the fact that the Earth’s hydrosphere has been existing for roughly 4 billion years, it is still changing shape. This is created by seafloor spreading and continental drift, which
Overview Carnegie Mellon University (CMU) is a private research university in Pittsburgh, Pennsylvania, United States. Established in 1900 by philanthropist Andrew Carnegie as the Carnegie Technical Schools, the institution became the Carnegie Institute of Technology in 1912. In 1967, it merged with the Mellon Institute of Industrial Research, forming what is now Carnegie Mellon University.

A microprocessor is a computer processor where the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer’s central processing unit. The integrated circuit is capable of interpreting and executing program instructions
Electrical Engineering (EE) is a core branch of engineering that focuses on the study, design, and application of systems and devices that use electricity, electronics, and electromagnetism. It encompasses a vast range of subfields, from the generation and distribution of electrical power to advanced electronic systems, communications, and control technologies. Electrical engineering is foundational to
