Thomas Adams invented modern chewing gum in 1869 while experimenting with chicle, a natural rubber from the sapodilla tree. He originally intended to use it as a rubber substitute but found it made better chewing gum, founding the American Chicle Company.

Orville and Wilbur Wright invented, built, and flew the world's first successful airplane in 1903 at Kitty Hawk, North Carolina. Their three-axis control system made fixed-wing powered flight possible and remains the standard for aircraft today.

Rudolph Diesel invented the diesel engine in the 1890s, patenting it in 1892. The diesel engine works on compression ignition rather than spark ignition, making it more efficient for heavy-duty applications like trucks, ships, and industrial machinery.

Thomas Alva Edison invented the phonograph (1877), perfected the practical lightbulb (1879), and played a pivotal role in developing motion pictures. His inventions established the modern electric and entertainment industries, earning him over 1,000 patents.

Biotechnology uses living organisms, cells, and enzymes to produce useful products on an industrial scale. It includes making drugs, vaccines, hormones, and antibiotics through fermentation processes using microorganisms like bacteria and yeast.

Haematology is the branch of medicine concerned with the study of blood, blood-forming organs, and blood diseases. It covers red and white blood cells, platelets, bone marrow, and conditions like anemia, leukemia, and clotting disorders.

Phycology (or algology) is the branch of biology that studies algae, including their classification, physiology, ecology, and uses. Algae range from microscopic diatoms to giant kelp forests and are crucial for oxygen production and aquatic ecosystems.

Phonetics is the study of speech sounds - how they are produced (articulatory), transmitted (acoustic), and perceived (auditory). It analyzes the physical properties of spoken language sounds, unlike phonology which studies sound patterns abstractly.

Mycology is the branch of biology concerned with the study of fungi, including their genetics, biochemical properties, taxonomy, and uses. Fungi include yeasts, molds, mushrooms, and are essential for decomposition, medicine (antibiotics), and food production.

Telepathy is defined as communication between two minds at a distance without using known sensory channels or physical interaction. The given definition 'Communication between two minds at a distance with the help of emotions thoughts and feelings' correctly describes the concept of telepathy. Taxonomy is classification, Physiology studies living organisms, and Neurology studies the nervous system - none match the definition.
