Explore the evolution of the theory of the atom - with an opportunity to get up close and personal with real experimental apparatuses. Some live data collection and analysis included.

Can you hear a magnet? Can you see a spin? What is the field in the nucleus of an iron atom? Why do our magnets explode if we don't feed them $4000 of liquid helium every year? Answers to all these questions and more!

Explore the evolution of the theory of the atom - with an opportunity to get up close and personal with real experimental apparatuses such as a Crookes tube, Rutherford's gold foil experiment, double-slit interference, cloud chamber trajectories, the photoelectric effect, discharge tubes, and a Stern-Gerlach apparatus. Some live data collection and analysis included.

From "opposites attract and likes repel" to why we say an atom has protons, neutrons, and electrons - an experimental journey into the basics of chemistry.

Discover the reality of the quantum model. Figure out what stops protons from pushing each other out of the nucleus. Impress your chemistry teacher with these and more!

Break protons and neutrons into quarks and gluons, think about waves, learn about energy and the rest of the Standard Model. For pure enjoyment - topics you won't see for 4+ years. First half is an overview, the rest is pure math.

Discover the reality of the quantum model. Figure out what stops protons from pushing each other out of the nucleus. Impress your first chemistry teacher with these and more!

Break protons and neutrons into quarks and gluons, think about waves, learn about energy and the rest of the Standard Model. For pure enjoyment - topics usually covered after high school. First half is an overview, the rest is pure math.

The essential properties of n-dimensional worlds. No classification of shapes, angle-finding, or proofs - just thought experiments about funky objects.

No magnitude. No direction. No arrows. No lies. The general truth about day 1 of every STEM class.

From Federalist Papers about factions to the Constitution, Jackson, slavery, populists and progressives, wars, civil rights, conservatives, and Trump. The themes they love in AP US History.

From Greek philosophy to models of the atom to relativistic quantum field theories, explore in depth how experiments have shaped the modern understanding of the constituents of matter.
