Self-assembly processes can also be observed in systems of macroscopic building blocks. These building blocks can be externally propelled [42] or self-propelled. [43] Since the 1950s, scientists have built self-assembly systems exhibiting centimeter-sized components ranging from passive mechanical parts to mobile robots. [44]

Lipids (oleaginous) are chiefly fatty acid esters, and are the basic building blocks of biological membranes. Another biological role is energy storage (e.g., triglycerides ). Most lipids consist of a polar or hydrophilic head (typically glycerol) and one to three non polar or hydrophobic fatty acid tails, and therefore they are amphiphilic .

The single-stranded nature of protein molecules, together with their composition of 20 or more different amino acid building blocks, allows them to fold in to a vast number of different three-dimensional shapes, while providing binding pockets through which they can specifically interact with all manner of molecules.
Capital accumulation is the dynamic that motivates the pursuit of profit, involving the investment of money or any financial asset with the goal of increasing the initial monetary value of said asset as a financial return whether in the form of profit, rent, interest, royalties or capital gains.
This accounting definition of assets includes items that are not owned by an enterprise, for example a leased building (Finance lease), but excludes employees because, while they have the capacity to generate economic benefits, an employer cannot control an employee. In economics, an asset (economics) is any form in which wealth can be held.
The idea that matter was built of discrete building blocks, the so-called particulate theory of matter, appeared in both ancient Greece and ancient India. [6] Early philosophers who proposed the particulate theory of matter include the Indian philosopher Kaṇāda ( c. 6th century BCE ), [ 7 ] and the pre-Socratic Greek philosophers Leucippus ...
