This principle states that two identical fermions cannot occupy the same quantum state within a quantum system simultaneously.

Pauli exclusion principle

These variations of an element, differing in the number of neutrons, can affect a compound’s physical properties.

Isotopes/Isotopic Variations

This molecule, essential for life, stores genetic information and is made up of a long chain of nucleotides.

DNA

This scientist’s 1869 publication laid the foundation for the modern periodic table of elements.


Dmitri Mendeleev

If two lasers of differentfrequencies are shone into thesame medium, how would theirspeeds compare?

Both lasers would travel at the speed of light in thatmedium, as the speed depends on the refractiveindex, not frequency.

These elements, found in the d-block of the periodic table, often form colorful compounds and have variable oxidation states.

Transition metals

This organelle is responsible for producing energy in the form of ATP.

mitochondrion

This 19th-century English naturalist proposed the theory of evolution after his voyage on the HMS Beagle.

Charles Darwin

Describe the Casimir effect and its implications for quantum field theory.
The Casimir effect is the attractive force between two uncharged, parallel plates in a vacuum, caused by quantum fluctuations of the electromagnetic field. It confirms the reality of zero-point energy.

This theoretical region on the periodic table is believed to contain superheavy elements that could have unusually long half-lives and potential applications in fields like medicine or technology.

Island of stability

300

This process, where messenger RNA is used to synthesize proteins, occurs after transcription and involves ribosomes translating the mRNA sequence into an amino acid chain.

Translation

In 1928, he discovered penicillin, marking the beginning of the antibiotic era.

Alexander Fleming

Explain how quantum tunneling enables nuclear fusion in stars.

Quantum tunneling allows particles to overcomethe Coulomb barrier (electrostatic repulsionbetween protons) despite not having enoughclassical energy to do so

400

This highly reactive and unstable compound of xenon can be isolated by cooling it to very low temperatures and using an inert atmosphere to prevent its breakdown.

Xenon hexafluoride (XeF₆)

400

This enzyme adds repetitive DNA sequences to the ends of chromosomes, helping protect them from shortening, which is important for cell division and is often active in cancer cells.


Telomerase

400

This lesser-known 20th-century physicist predicted the existence of antimatter and proposed a now-famous equation relating quantum mechanics and special relativity.

Paul Dirac

How would a gyroscope behave ifit were placed in orbit around arapidly spinning neutron star?​​​​​​​​
The gyroscope’s axis would precess due to frame-dragging caused by the neutron star’s intensegravitational field and rapid spin (Lense-Thirringeffect).

This type of reaction, where the product can be converted back to the original state by exposure to light, is often used in light-sensitive data storage systems.

Photochromic reaction

500

This process, occurring in the mitochondria, involves the transfer of electrons through a series of protein complexes and is crucial for the production of ATP through oxidative phosphorylation.


electron transport chain

This 18th-century scientist developed the principle of conservation of mass and is often called the "Father of Modern Chemistry." He was executed during the French Revolution.
