Robert Brown
A botanist who discovered the nucleus in plant cells and described Brownian motion, the random movement of particles in a fluid.
Most quoted
"I have, however, been enabled to satisfy myself that the particles or molecules of the pollen of plants, and indeed of many other organic as well as inorganic bodies, when suspended in water, are in a state of constant and rapid oscillatory motion."
— from A Brief Account of Microscopical Observations Made in the Months of June, July, and August, 1827, on the Particles Contained in the Pollen of Plants; and on the General Existence of Active Molecules in Organic and Inorganic Bodies., 1827
"This motion was such as to satisfy me, after frequently repeated observation, that it was not caused either by currents in the fluid, or by its gradual evaporation, but belonged to the particle itself."

All quotes by Robert Brown (343)
The nucleus is the fundamental organizing center of the cell.
In the pollen grains, I observed a continuous motion which must be inherent to the particles themselves.
Nature's diversity in the plant kingdom is boundless and worthy of endless study.
The cell is the basic unit of life, a microcosm of creation.
Through the microscope, we glimpse the secrets of the universe.
Brownian motion reveals the unseen dance of matter.
In every seed lies the potential of a forest.
The study of botany humbles the soul before nature's grandeur.
Particles in suspension move as if alive, defying our expectations.
Life's essence is encoded in the smallest forms.
The nucleus governs as the king of the cellular realm.
Exploration of the Australian flora opened my eyes to wonders untold.
In the quiet of the lab, truth emerges from the chaos.
The irregular motion of granules is a phenomenon of perpetual interest.
Plants teach us resilience in the face of adversity.
Discovery is the child of patient observation.
The cell wall is nature's fortress, protecting life's core.
To understand the whole, begin with the parts unseen.
Brownian movement persists even in the stillest solutions.
My voyages have shown me that knowledge is an endless sea.
