Science Inventions and Discoveries

The Lockheed Martin X-33 was an unmanned, sub-scale technology demonstrator for the VentureStar, a proposed reusable launch vehicle. The project was intended to test the 'single-stage-to-orbit' concept before being canceled in 2001.

Halley's Comet orbits the Sun approximately every 75-76 years. Its last appearance was in 1986, so the next return will be around 2061 (1986 + 75 = 2061). The comet has been observed since ancient times and is the only short-period comet visible to the naked eye.

The Sun is the closest star to Earth, located at an average distance of about 93 million miles. Alpha Centauri is the closest star system to our solar system, but not the closest star to Earth itself.

Bats use echolocation to navigate and hunt in the dark. They emit high-frequency sound waves that bounce off objects, allowing them to 'see' their surroundings through sound. Owls have excellent vision but do not use sonar.

Humans are warm-blooded (endothermic) animals, meaning we maintain a nearly constant internal body temperature regardless of the environmental temperature. Cold-blooded animals (ectotherms) rely on external heat sources.

Humans are classified as mammals because they possess mammary glands (which produce milk for offspring), have hair or fur, and are warm-blooded vertebrates. This is a fundamental biological classification.

Coprophagy refers to the consumption of feces. Many animals, such as rabbits and various insects, engage in this behavior to recover nutrients that were not fully absorbed during the first passage through the digestive tract.

Aristotle is traditionally known as the 'Father of Zoology' due to his extensive observations of animals and his attempts to classify them based on their characteristics and habitats in works like 'History of Animals'.

Mary Anderson was granted the first patent for an automatic car window cleaning device (windshield wipers) in 1903. The question uses 'Windshield' as shorthand for the wiper system. Marie Curie and Katherine Blodgett worked in physics and chemistry.

Patricia Billings, a sculptor, invented Geobond, a non-toxic, fireproof building material, while trying to find a durable plaster for her art. Valerie Thomas and Bette Nesmith Graham are famous for unrelated inventions.

Katherine Blodgett was the first woman to earn a PhD in physics from Cambridge and invented 'invisible' or non-reflecting glass by adding monomolecular film coatings to surfaces. This technology is essential for cameras and eyeglasses.

Marie Curie is renowned for her pioneering research on radioactivity and her development of mobile X-ray units during WWI. While Wilhelm Röntgen discovered X-rays, Curie's work was fundamental to the technology's medical application.

Sally Fox is an inventor and breeder who developed 'FoxFibre,' the first commercially viable naturally colored cotton that could be spun by machines. Hedy Lamarr co-invented frequency hopping, and Ruth Handler created the Barbie doll.

Bette Nesmith Graham, a secretary, invented 'Mistake Out' (later Liquid Paper) in her kitchen to correct typing errors. Mary Anderson invented windshield wipers, and Margaret Knight invented the flat-bottomed paper bag machine.

Josephine Garis Cochran invented the first commercially successful hand-powered dishwasher in 1886. Lyda Newman is known for hairbrushes, and Valerie Thomas for the illusion transmitter. Julie Newmar is an actress, not an inventor.

Amanda Theodosia Jones, an American inventor, patented the vacuum-packed canning process in 1873. Her innovation involved using a vacuum to remove air from containers before sealing them, which significantly improved food preservation by reducing bacterial growth. This technique laid groundwork for modern vacuum-sealing food storage methods. Katherine Blodgett invented non-reflective glass, while Alice Parker invented a gas-powered heating furnace.

Valerie Thomas, a NASA scientist, invented the Illusion Transmitter in 1980. This optical device uses concave mirrors to create 3D optical illusions, capturing an image at one point and projecting it as a three-dimensional illusion at another point. Her invention received a NASA patent and has applications in medical imaging, television, and video technology. Mary Walton invented pollution-reduction devices, Mary Anderson invented windshield wipers, and Carol Wior invented slimming swimwear.

Vitamin B12 (cobalamin) is essential for DNA synthesis and red blood cell formation in bone marrow. Deficiency causes megaloblastic anemia where bone marrow produces immature, abnormal red blood cells. B1, B2, and B6 are important for metabolism but not directly critical for marrow function like B12.
