Which Is Worse: Underpopulation Or Overpopulation?
To learn more about this topic, start your googling with these keywords:
Overpopulation: a situation in which there are too many people for the amount of food, materials, and space available.
Underpopulation: a situation in which there are too few people to realize the economic potential of an area or support its population's standard of living.
Exponential growth: a pattern of data that shows greater increases with passing time, creating the curve of an exponential function.
Extreme poverty: an income below the international poverty line of ~$2/day
Total fertility rate: the average number of children born to each woman over her lifetime.
Population bomb: a theory that the human population would grow faster than available food supplies.

What if We Replaced Nuclear With Potatoes
To learn more about this topic, start your googling with these keywords:
Calorie: the energy needed to raise the temperature of 1 gram of water through 1°C (now usually defined as 4.1868 joules).
Energy: power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.
Joule: the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour.
Watt: the SI unit of power, equivalent to one joule per second, corresponding to the power in an electric circuit in which the potential difference is one volt and the current one ampere.
Watt-hour: a measure of electrical energy equivalent to a power consumption of one watt for one hour.

How We Learned That Water Isn't An Element
To learn more about this topic, start your googling with these keywords:
Chemical element: is a species of atoms that have a given number of protons in their nuclei. Chemical elements cannot be broken down into simpler substances by any chemical reaction.
Atom: is the smallest unit of ordinary matter that forms a chemical element.
Molecule: is a group of two or more atoms held together by attractive forces known as chemical bonds.
Inflammable air: an old name for hydrogen.
Hydrogen: is the most abundant chemical substance in the universe. Early chemists identified hydrogen gas because it was colorless, odorless and highly combustible. Hydrogen means "maker of water" in Greek.
Dephlogisticated air: an old name for oxygen.
Oxygen: is Earth's most abundant element. Early chemists identified oxygen gas because it was colorless, odorless and was essential for respiration and combustion.
Diatomic molecules: are molecules composed of only two atoms, of the same or different chemical elements. At standard conditions, both hydrogen and oxygen are gasses of diatomic molecules (H2 and O2, respectively).
Water: is an inorganic, transparent, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms.
Combustion (or burning): is a chemical reaction between a fuel and an oxidizing agent (like oxygen gas), that produces oxidized, often gaseous products, in a mixture termed as smoke.
Electrolysis: is a technique that uses direct electric current to drive an otherwise non-spontaneous chemical reaction.
Avogadro's Law (sometimes referred to as Avogadro's hypothesis): is an experimental gas law that states that equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.

From the creators of the popular science show with millions of YouTube subscribers comes the MinuteEarth podcast. Every episode of the show dives deep into a science question you might not even know you had - but once you hear the answer, you’ll want to share it with everyone you know. Our team of scientists digs into the research and breaks it down into a short, entertaining explanation jam-packed with science facts and terrible puns. We’ll tell the incredible story of how monkeys crossed the Atlantic ocean on natural rafts, and we’ll explain why it gets hotter the deeper you dig underground.
