A solar cooker, also known as a solar oven or solar stove, is a device that utilizes the energy from sunlight to cook or heat food. It uses the principles of concentrating solar power and the greenhouse effect to trap and convert solar radiation into heat energy. Solar cookers are typically used in areas where
Refraction is a phenomenon that occurs when light waves travel from one medium to another and change direction. It happens because the speed of light is different in different substances. When light passes through a medium with a different optical density (refractive index), such as air to water or air to glass, it bends or
Nikola Tesla was a renowned inventor, electrical engineer, and physicist who made significant contributions to the fields of electricity and magnetism. He was born on July 10, 1856, in Smiljan, which was part of the Austrian Empire (present-day Croatia), and he passed away on January 7, 1943, in New York City, United States. Here are

Staphylococci are a type of cocci bacteria that form in grape-like clusters. They are Gram-positive bacteria and are facultative anaerobic organisms, meaning they are capable of growth both aerobically and anaerobically. Staphylococcus bacteria are commonly found on the skin or in the nose of many healthy people. Most of the time, these bacteria cause no
Cocci bacteria are generally round, oval or spherical in shape¹. They can grow in pairs, chains, or clusters, depending on their orientation and attachment during cell division¹. Based on the arrangement of cocci cells, they can be further divided into: In contrast to many bacilli-shaped bacteria, most cocci bacteria do not have flagella and are
Bacteria can have different shapes based on how they divide and grow. The three basic shapes of bacteria are: coccus, bacillus, and spiral¹²³. An average coccus is about 0.5-1.0 micrometer (µm) in diameter, while an average bacillus is about 0.5-1.0 µm wide and 1-4 µm long¹. Spiral bacteria can vary in size and shape depending
Bacteria are microscopic, single-celled organisms that belong to the prokaryotic group¹. They are very diverse and can live in many different environments, such as soil, water, hot springs, radioactive waste and even inside other organisms¹². Bacteria play a vital role in many biological processes, such as recycling nutrients, fixing nitrogen, decomposing dead matter, producing cheese
Hill’s reaction is a process in photosynthesis where light energy is used to split water molecules into oxygen and hydrogen¹. The process is named after English scientist Daniel Hill, who first described it in 1887¹. In vivo, the final electron acceptor in the light reactions is NADP+¹². The Hill reaction can be measured in isolated
Adenosine triphosphate is a molecule that carries energy within cells. It is the main energy currency of the cell, and it is an end product of the processes of photophosphorylation, cellular respiration, and fermentation. It is composed of three components: a nitrogenous base (adenine), the sugar ribose, and a chain of three phosphate groups bound
