Top 10 STEM Words We Should Know!

1. Entropy

[ en-truh-pee ] Noun

Definition: A measure of disorder or randomness in a system. Why it matters: It explains why ice melts, why your room gets messy, and why the universe tends toward chaos. Basically, nature loves disorder!

Example: "The entropy of the system increased as the ice cube melted into water."

2. Algorithm

[ al-guh-rith-uhm ] Noun

Definition: A step-by-step set of instructions for solving a problem or completing a task. Why it matters: Without algorithms, your favorite apps, search engines, and even self-driving cars wouldn’t work. Think of it as a recipe but for computers.

Example: "Google’s search engine uses complex algorithms to show you the most relevant results."

3. Isotope

[ ahy-suh-tohp ] Noun

Definition: Variations of an element that have the same number of protons but different numbers of neutrons. Why it matters: Isotopes help in medical imaging, carbon dating, and even nuclear energy. Science wouldn't be the same without them!

Example: "Carbon-14 is a radioactive isotope used in archaeology to date ancient artifacts."

4. Vector

[ vek-ter ] Noun

Definition: A quantity that has both magnitude and direction (like force or velocity). Why it matters: Ever wondered how GPS knows where you are and where you’re going? It’s all about vectors!

Example: "The wind’s velocity vector pointed northwest at 20 kilometers per hour."

5. Catalyst

[ kat-l-ist ] Noun

Definition: A substance that speeds up a chemical reaction without being consumed. Why it matters: Catalysts make reactions happen faster—from digestion in your stomach to making eco-friendly fuel!

Example: "Enzymes act as catalysts in the body, speeding up important chemical reactions."

6. Quantum

[ kwon-tuhm ] Noun

Definition: The smallest possible amount of something, especially energy. Why it matters: Quantum physics explains mind-blowing things like teleportation (yes, really) and the existence of parallel universes!

Example: "A photon represents a quantum of light energy."

7. Resistance

[ ri-zis-tuhns ] Noun

Definition: The opposition to the flow of electric current in a circuit. Why it matters: Without resistance, we wouldn’t have light bulbs, heaters, or even the concept of Ohm’s Law.

Example: "The metal wire had low resistance, allowing electricity to flow easily."

8. Polymer

[ pol-uh-mer ] Noun

Definition: A large molecule made up of many repeating units. Why it matters: Plastics, DNA, and even slime (yes, the one you made in school) are all polymers!

Example: "DNA is a natural polymer that carries genetic information."

9. Equilibrium

[ ee-kwuh-lib-ree-uhm ] Noun

Definition: A state of balance where opposing forces are equal. Why it matters: It’s why bridges don’t collapse, why ecosystems stay stable, and why our bodies maintain a steady temperature.

Example: "The chemical reaction reached equilibrium when the forward and reverse reactions occurred at the same rate."

10. Hypothesis

[ hahy-poth-uh-sis ] Noun

Definition: A testable explanation or prediction based on observations. Why it matters: It’s the foundation of the scientific method—every cool discovery started with a hypothesis!

Example: Her hypothesis suggested that plants would grow faster when exposed to classical music.

The term "tachyon" was coined by Gerald Feinberg in 1967. . Most scientists do not believe that tachyons exist. Einstein's theory of special relativity states that nothing can accelerate faster than the speed of light, while tachyons are theorized to be constantly traveling faster than the speed of light. If a tachyon did exist, it would have an imaginary number as its mass. .

This phenomenon is a classical test of General Relativity. . Gravitational redshifts are an important effect in satellite-based navigation systems such as GPS. If the effects of general relativity were not taken into account, such systems would not work at all. . .

Electrophoresis is a laboratory technique used to separate DNA, RNA, or protein molecules based on their size and electrical charge. An electric current is used to move molecules to be separated through a gel. Pores in the gel work like a sieve, allowing smaller molecules to move faster than larger molecules. The conditions used during electrophoresis can be adjusted to separate molecules in a desired size range. . .

The term "day" is ambiguous, it can mean 1. The period when there is sunlight. 2. Complete 24 hours, and a few more meanings also exist for word "day". . So, to avoid this ambiguity, the above science term is used in literature to represent 24 consecutive hours. . .
