Science and Technology Quiz

Ada Lovelace wrote the first algorithm intended for Babbage's Analytical Engine in the 1840s, making her history's first computer programmer. Babbage designed the machine, Gates founded Microsoft, and Jobs co-founded Apple.

Dry ice is solid carbon dioxide that sublimates (turns directly from solid to gas) at -78.5°C. The 'Corbondioxide' option contains a typo but refers to the correct substance.

Sunlight takes approximately 8 minutes and 20 seconds (500 seconds) to reach Earth, traveling at 299,792 km/s across 150 million km. This is approximately 8 minutes.

Oracle was founded by Larry Ellison (along with Bob Miner and Ed Oates) in 1977. Bill Gates founded Microsoft, Larry Page co-founded Google, and Steve Wozniak co-founded Apple.

Sulfuric acid (H2SO4) is called the 'King of chemicals' due to its vast industrial applications, from fertilizers to chemical synthesis. It's the most-produced industrial chemical worldwide.

A rhino's horn is made of keratin - the same protein found in human hair and fingernails. It's not bone, teeth, or muscle tissue. The horn grows continuously throughout the rhino's life.

Louis Pasteur proved microbes existed in air through his swan-neck flask experiment (1859-1864), showing that microorganisms caused spoilage. Koch worked on germ theory and specific diseases, Aristotle lived before germ theory.

Ernest Rutherford discovered the proton in 1919 through nuclear experiments showing that nitrogen nuclei could be disintegrated by alpha particles, releasing hydrogen nuclei (protons). J.J. Thomson discovered the electron.

Larry Ellison co-founded Oracle Corporation (originally Software Development Laboratories) in 1977 with Bob Miner and Ed Oates. Bill Gates founded Microsoft, Larry Page co-founded Google, and Steve Wozniak co-founded Apple.

Sulphuric acid (H2SO4) is called the 'King of Chemicals' due to its enormous industrial importance - it's used in fertilizer production, petroleum refining, and chemical manufacturing. It has the highest production volume of any industrial chemical worldwide.

Sunlight takes approximately 8 minutes and 20 seconds (500 seconds) to travel from the Sun to Earth, based on Earth's average distance of 149.6 million km and light speed of 299,792 km/s. This is why we see the Sun as it was 8 minutes ago.

A rhino's horn is composed entirely of keratin - the same protein that makes up human hair and fingernails. It's not bone, teeth, or muscle tissue. This is why rhino horns can grow back if cut, unlike true horns which are permanent bone structures.

Ada Lovelace wrote the first algorithm intended for Charles Babbage's Analytical Engine in the 1840s, making history's first computer programmer. She was the daughter of Lord Byron and worked closely with Babbage on his mechanical computer designs.
