Refining form, 2026. Thit Senstius. Pen on paper.

Refining: the process of purification of a physical material.
The term is usually used of a natural resource that is almost in a usable form, but which is more useful in its pure form.
The term is broad, and may include more drastic transformations.
Methods such as (1) being compressed until liquified or (2) extraction with a selective solvent that dissolves away either the substance of interest, or the unwanted impurities.

In some cases by an alteration of the contact time it is possible to alter the selectivity of the extraction.

Many solids can be refined in an impure material; the regular structure tends to favor the desired material and exclude other kinds of particles.

Gravisphere, 2024. Ink on paper
Artist: Thit Senstius @thitsenstius

Gravisphere
/ˈɡrævəˌsfɪər/
NOUN
the area in which the gravitational force of a celestial body is predominant

Origin
[gravi(ty) + sphere]
Latin adjective gravis, meaning “heavy”.

Sphere Gravitational Force: Newton showed that the gravitational force on a body of mass m from a spherically symmetric body of total mass M whose center is located a distance r away is equivalent to the force on m from a point mass M located a distance r away

Gravitate
/ˈɡravɪteɪt/ verb
1. : to be drawn or attracted especially by natural inclination
2. PHYSICS: move towards attractive force. "the electron does not gravitate towards the nucleus"

Gravity
: a fundamental physical force that is responsible for bringing us back down to earth
: the natural attraction that any two masses have for each other; the force of gravity

First known use in print: Same year as “adaptable” was used in print for the first time.

Sphere
NOUN [C] (AREA)
range or area of activity

Spherolite (from Gr. sphere + -lit)
: spherical formation of thin crystal needles radiating from the center.

Ellipsoid : a sphere that has been stretched or compressed in one or more directions

Inescapable Inertia, 2023. Ink on paper. Artist: @thitsenstius

Inescapable Inertia
[ˌɪnɪˈskeɪpəbl ɪnˈɜːʃə]

A property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.

The power required to overcome friction and the inertia of the moving parts.

Physics: the tendency of a body to maintain its state of uniform motion unless acted upon by an external force

types:
- moment of inertia:
the tendency of a body to resist angular acceleration.
- mechanical phenomenon:
a physical phenomenon associated with the equilibrium or motion of objects

Synonyms: ineptus, rudis, indocilis, incapāx

Washout, 2025. Ink on paper (A2 format)

Outwash • / ˈaʊtˌwɒʃ/
noun
Geology.
• Minerals and sediments locked within the ice of a glacier when carried and deposited by the streams of water derived from melting glaciers.

Occurs naturally through the processes of weathering and erosion.
When broken down and subsequently transported by the action of water and ice or by the force of gravity acting on the particles.

Glaciers move downhill by the force of gravity and the internal deformation of ice.

Some irregular hills form when meltwater deposits sediments through openings in the interior of the ice.

Small amounts of stress can result in a large amount of strain, causing the deformation to become a plastic flow rather than elastic. Then, the glacier will begin to deform under its own weight and flow across the landscape.

The rate of internal flow, can be modeled as follows
Σ = kτ^n
where:
Σ = shear strain (flow) rate
τ = stress
n = a constant between 2–4
k = a temperature-dependent constant

A large piece of compressed ice, or a glacier, appears blue, due to water molecules absorbing other colors more efficiently than blue.

Glaciers furthermore appear blue due to the lack of air bubbles. All air is squeezed out by the increasing pressure.
