Scientists
This Serbian-American inventor, electrical engineer, and mechanical engineer is best known for his contributions to the development of alternating current (AC) electrical systems.
Who was Nikola Tesla?
This theory suggests that the universe began as an infinitely small, hot, and dense point roughly 13.8 billion years ago and has been expanding ever since.
What is the Big Bang theory?
This 18-year-old Indian chess grandmaster became the World Chess Champion in December 2024, defeating Ding Liren to claim the title, and is now the youngest player in history to do so.
Who is Gukesh D?
This process, often associated with the petroleum industry, involves the catalytic conversion of long-chain hydrocarbons into shorter, more valuable products like gasoline and diesel.
What is catalytic cracking?
This phenomenon describes the movement of molecules from an area of high concentration to an area of low concentration, playing a critical role in processes like diffusion and osmosis.
What is diffusion?
This French physicist proposed the wave-particle duality theory, suggesting that particles, such as electrons, exhibit both wave-like and particle-like properties, which earned him the Nobel Prize in Physics in 1929.
Who is Louis de Broglie?
This is the nearest galaxy to the Milky Way and is on a collision course with our galaxy, expected to merge in about 4 billion years.
What is the Andromeda Galaxy?
This Indian badminton player has won multiple medals at the World Championships and the Olympics, including a silver medal at the 2016 Rio Olympics.
Who is P.V. Sindhu?
This high-temperature process is used to extract metals from their ores by reducing them with a substance like carbon, typically performed in a blast furnace or a smelting furnace.
What is smelting?
This law, central to mass transfer, states that the flux of a solute through a medium is proportional to the concentration gradient and the diffusion coefficient of the solute in that medium.
What is Fick's Law of diffusion?
This English chemist and X-ray crystallographer made critical contributions to the understanding of the molecular structures of DNA, RNA, viruses, coal, and graphite.
Who was Rosalind Franklin?
This hypothetical particle, first proposed in the context of relativity, is said to travel faster than light, though it has not been observed and remains a speculative concept in physics.
What is a tachyon?
This American golfer, often regarded as one of the greatest of all time, has won 15 major championships, including five Masters titles, and is known for his incredible comeback after a series of personal and professional challenges.
Who is Tiger Woods?
This technique is used to separate charged particles from a liquid or gas phase by applying an electric field, commonly utilized in processes like the purification of water or the removal of particulate matter from exhaust gases.
What is electrostatic precipitation?
This ratio, in distillation columns, defines the amount of liquid returned to the column as reflux relative to the liquid taken as the distillate, influencing the separation efficiency and the number of stages required for a desired product purity.
What is the reflux ratio?
This Indian-American astrophysicist, who won the Nobel Prize in Physics in 1983, is known for his work on the structure and evolution of stars, particularly the limit named after him, which describes the maximum mass of a stable white dwarf star.
Who is S. Chandrasekhar?
This American astronomer is best known for his observation that the universe is expanding, leading to the formulation of a Law, which suggests that galaxies are moving away from each other at speeds proportional to their distance.
Who is Edwin Hubble?
This New Zealand cricketer holds the record for the highest individual score in a Cricket World Cup match, with 237* runs against West Indies in the 2015 tournament.
Who is Martin Guptill?
This thermal cracking process, used in refineries, involves the mild heating of heavy crude oil fractions to break down large molecules into lighter, more valuable products like gasoline and diesel while reducing the viscosity of residual oils.
What is visbreaking?
This method, often used in the design of distillation columns, determines the number of theoretical stages required for a given separation, using a graphical approach that plots the operating line and equilibrium curve on a _________ diagram.
What is the McCabe-Thiele method?
This English mathematician and writer is often considered the first computer programmer for her work on Charles Babbage's early mechanical general-purpose computer, the Analytical Engine.
Who was Ada Lovelace?
This supermassive black hole, located in the center of the galaxy, became the first black hole ever imaged by the Event Horizon Telescope in 2019, showing its distinct glowing ring.
What is M87?
This Russian fighter defeated Conor McGregor in 2018 at UFC 229 to retain his UFC lightweight title, maintaining his undefeated record and sparking a heated rivalry between the two.
Who is Khabib Nurmagomedov?
the difference between the wet bulb temperature (WBT) of the surrounding air and the temperature of the water leaving the cooling tower
What is Approach temperature?
He was an American chemical engineer and founding member of the National Academy of Engineering. He published the first text on mass transfer in 1937 entitled Absorption and Extraction , which was republished in 1974 as Mass Transfer.
Who was Thomas Kilgore Sherwood?
