Scientific Studies, Names & Discoveries

An altimeter (note correct spelling) is an instrument used to measure altitude, typically in aviation and mountaineering. It works by detecting changes in atmospheric pressure which decreases with increasing elevation.

Oology is the branch of ornithology (study of birds) that specifically focuses on the study of bird eggs, including their structure, development, and classification. The term comes from the Greek word 'oon' meaning egg.

Frederick Soddy was a British radiochemist who, along with Ernest Rutherford, demonstrated that radioactive decay involves the transformation of one element into another. He coined the term 'isotope' and received the 1921 Nobel Prize in Chemistry for his work on isotopes.

Gossypium hirsutum is the scientific botanical name for upland cotton, which is the most widely cultivated species of cotton globally. The genus name comes from the Latin word for cotton, and 'hirsutum' means hairy, referring to the plant's characteristics.

Sequoia gigantea refers to the giant sequoia (Sequoiadendron giganteum), which is indeed the largest tree in the world by volume. These massive trees can grow over 250 feet tall and are found naturally only in the Sierra Nevada mountains of California.

Histology is the study of the microscopic structure of biological tissues. It involves examining tissues at the cellular level using various staining and microscopy techniques to understand their organization and function in both plants and animals.

Plaster of Paris is calcium sulphate hemihydrate (CaSO4·0.5H2O), a white powder that forms a hard paste when mixed with water and then dries. It's called 'Plaster of Paris' because gypsum, the main source material, was abundantly available near Paris.

Trichloromethane (CHCl3) is commonly known as chloroform. It's a dense, sweet-smelling organic compound that was historically used as an anesthetic. The name 'chloroform' is a contraction of its chemical name: 'chloro' (from chlorine) and 'form' (from methane/CH4).

Dr. Charles H. Townes was an American physicist who invented the maser (microwave amplification by stimulated emission of radiation) and later co-invented the laser with Arthur Schawlow. He received the 1964 Nobel Prize in Physics for this fundamental work in quantum electronics.

A scotophyte (from Greek 'skotos' meaning darkness) is a plant that can grow or survive in dark conditions. These plants have adaptations that allow them to thrive with minimal or no light, such as enhanced chlorophyll sensitivity or alternative energy-gathering mechanisms.

The Atomic Energy Commission (AEC) of India was established in 1948 under the Atomic Energy Act to oversee nuclear energy research and development. Homi Bhabha was its first chairman, and it played a crucial role in establishing India's nuclear program.

Phycology is the branch of biology that studies algae. The term comes from the Greek word 'phykos' meaning seaweed or algae. It is distinct from bacteriology (study of bacteria) and protozoology (study of protozoa).

The Central Tobacco Research Institute is located in Rajahmundry, Andhra Pradesh. It was established in 1947 and is under the Indian Council of Agricultural Research (ICAR). Anand is known for dairy research, while Nagpur has multiple research institutions but not this one.

An obligate parasite is an organism that can only survive and reproduce on living host organisms. Unlike facultative parasites that can live independently, obligate parasites cannot complete their life cycle without a host. This term applies to certain fungi, viruses, and bacteria.

Sir Joseph Swan is credited with the invention of rayon, the first artificial fiber, in the late 19th century. He was a British physicist and chemist who worked on various inventions including early electric lighting. Chrome plating, lactometer, and spindles have different inventors and purposes.

Morphology is the biological study of the form and structure of organisms and their specific structural features. This includes external appearance (shape, size, color) and internal structure (anatomy). The other options are not standard biological terms.

Oryza sativa is the scientific (botanical) name for Asian rice, one of the most important cereal crops globally. The term comes from Latin, with 'Oryza' being the rice genus and 'sativa' meaning cultivated. It is not related to Satan worshippers or animal names.

Dakshin Gangotri is India's first permanent research base in Antarctica, established in 1983. It is located in the Schirmacher Oasis region. The name connects to the Gangotri glacier in India, symbolizing India's scientific presence in the southern polar region.
