Voxel
A voxel represents a value on a regular grid in three-dimensional space.
Basically, the 3D equivalent of the 2D pixel.

Definition: Accretion Disk
Accretion Disk
The disk of stuff you see circling black holes in artist renderings like the one in the picture.
More formally..
An accretion disk is a structure (often a circumstellar disk) formed by diffuse material in orbital motion around a massive central body. The central body is typically a star. Friction causes orbiting material in the disk to spiral inward towards the central body.
Hear about accretion disks and a LOT more interesting and mind blowing stuff about astrophysics in the TEDRadio Hour podcast below!

Definition: Radical Transparency
Radical Transparency
Radical transparency is a phrase used across fields of governance, politics, software design and business to describe actions and approaches that radically increase the openness of organizational process and data. Also used for showing the internal workings of a product, service, or organization that are usually hidden from view, when applied even more innovatively than just within an organization.
- Wikipedia (first sentence)
The examples of radical transparency, when you can find it, are really refreshing and innovative for how things can be done within an organization! In an equally innovative way, the 99% Invisible podcast below talks about how the transparency was used to let customers/users fully look into the operations of something so they can appreciate what goes into it rather than oversimplifying it and not appreciating it. The best example, for me, was how the operators of the shinkansen high speed bullet trains in Japan let riders see the amazing work done by the cleaning crews in seven minutes between rides, turning it into a spectacle of theatrical wonder, rather than hiding it all and getting angry and impatient riders wondering why they have to wait “so long” to get on to the trains between rides! See video at bottom. Brilliant!

Definition: Self Determination Theory (SDT)
Self Determination Theory (SDT)
Self-determination theory (SDT) is a macro theory of human motivation and personality that concerns people’s inherent growth tendencies and innate psychological needs. It is concerned with the motivation behind choices people make without external influence and interference. Practically, it states that for life to be happy and meaningful, we all (universally) need a good extent of life situations where we feel we have competence, autonomy, and relatedness (ability to relate to others and they to you).

“Nutrients” in the tweet should have been “nutriments”, which means something that nourishes (Merriam-Webster Dictionary), which is close enough to “nutrients” that the definition source lists nutrients as a pretty close synonym.
Definition: Truth Default Theory (TDT)
Truth Default Theory (TDT)
Truth Default Theory is a communication theory which predicts and explains the use of veracity and deception detection in humans. This theory gets its name from its central idea which is the truth-default state. This idea suggests that people presume others to be honest because they either don’t think of deception as a possibility during communicating or because there is insufficient evidence lending them unable to prove they are being deceived.
