This theory explains how Earth's crustal plates drift and collide over millions of years.

What is plate tectonics?

This Nobel-winning technique uses a heat-stable polymerase, originally isolated from a bacterium living in hot springs, to exponentially amplify a target DNA sequence in vitro.

What is PCR (polymerase chain reaction)?


300

This effect describes how adding a soluble salt that shares an ion with a slightly soluble salt actually decreases the latter's solubility.


What is the common-ion effect?

This decision problem asks whether some assignment of true/false to variables can satisfy a given Boolean formula — the first problem proven NP-complete, via the Cook–Levin theorem.



What is the Boolean satisfiability problem (SAT)?




300

This 1905 theory rests on two postulates: the laws of physics are identical in all inertial reference frames, and the speed of light in a vacuum is the same for every observer.

In the Hardy-Weinberg equation p² + 2pq + q² = 1, this term represents the expected frequency of heterozygotes in a population at genetic equilibrium.

What is 2pq?

400

Its purpose is to form carbon-carbon bonds to build larger organic molecules.

It is a reaction between a nucleophile and an electrophile.

(CH3MgBr) Methyl magnesium bromide is a widely used Grignard reagent.

Below a critical temperature, electrons in certain materials form these bound pairs, allowing electrical current to flow with exactly zero resistance.


What are Cooper pairs (giving rise to superconductivity)?

This radiometric dating method relies on the decay of a potassium isotope, with a half-life of about 1.25 billion years, into an inert gas — useful for dating very old volcanic rock.


What is potassium-argon dating?

This spectroscopic technique exploits the magnetic behavior of nuclei like hydrogen-1 or carbon-13 in a strong external field to map out a molecule's structure.

What is NMR (nuclear magnetic resonance) spectroscopy?

A programming language type system that lets you mix static typing (checking types before running code) and dynamic typing (checking types while code runs) within the same program

What is Gradual Typing?
