STEM & History Components: Formulas and Timelines

This post shows the academic components in action — built for students writing about math, chemistry, physics, and history.

Math: formulas inline and as blocks

You can drop math right into a sentence, like the Pythagorean theorem $a^2 + b^2 = c^2$ , or set it apart as a display equation:

x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

The quadratic formula

When you want to teach a result, the formula card lays out the equation with a legend explaining every variable:

Newton's second law

\vec{F} = m\vec{a}

Physics: quantities with units

Reported measurements look right with proper units and uncertainty: gravitational acceleration at sea level is $9.81 \pm 0.02\,\mathrm{m/s^2}$ , and the speed of light is $2.998 \times 10^8\,\mathrm{m/s}$ .

Chemistry: reaction equations

Chemical equations use mhchem syntax, so arrows, subscripts, and states all render correctly:

\ce{2H2 + O2 -> 2H2O}

Combustion of hydrogen

\ce{CO2 + H2O <=> H2CO3}

Age of Exploration

1492

Columbus reaches the Americas

Sailing west in search of a route to Asia, Columbus made landfall in the Bahamas, opening sustained contact between Europe and the Americas.

1498

Da Gama reaches India

Vasco da Gama completed the first sea route from Europe to India by rounding the southern tip of Africa.

1513

Balboa sights the Pacific

Crossing the Isthmus of Panama, Balboa became the first European to see the eastern Pacific Ocean.

1519

Magellan's voyage begins

The expedition that would first circumnavigate the globe set out from Spain under Ferdinand Magellan.

1522

Circumnavigation completed

The Victoria returned to Spain, completing the first voyage around the world.

That's the full set — formulas for the sciences and a timeline for the humanities, all matching the notebook aesthetic.
