Commerce is the activity of buying and selling of goods and services. The system includes legal, economic, political, social, cultural and technological systems that are in operation in any country or internationally. Thus, commerce is a system or an environment that affects the business prospects of economies. It can also be defined as a component of business which includes all activities, functions involved in transferring goods from producers to consumers. — Wikipedia
Business is the activity of making one’s living or making money by producing or buying and selling products (such as goods and services). — Wikipedia
Money is any item or verifiable record that is generally accepted as payment for goods and services and repayment of debts, such as taxes, in a particular country or socio-economic context. The main functions of money are distinguished as: a medium of exchange, a unit of account, a store of value and sometimes, a standard of deferred payment. Any item or verifiable record that fulfils these functions can be considered as money. — Wikipedia

Science
Economics is the science that studies the production, distribution, and consumption of goods and services. Economics focuses on the behavior and interactions of economic agents and how economies work. Microeconomics is a field which analyzes what’s viewed as basic elements in the economy, including individual agents and markets, their interactions, and the outcomes of interactions. Individual agents may include, for example, households, firms, buyers, and sellers. Macroeconomics analyzes the economy as a system where production, consumption, saving, and investment interact, and factors affecting it: employment of the resources of labor, capital, and land, currency inflation, economic growth, and public policies that have impact on these elements. — Wikipedia

Communication, transportation and commerce have been intertwined since the beginning of human history, and they remain closely related.
The success of the first electronic telegraph line in 1844 opened an era of modern communication. Before the telegraph there existed no separation between transportation and communication. Information traveled only as fast as the messenger who carried it. — D. J. Czitrom, Media and the American Mind
This reality was even codified in the Dewey Decimal library classification system:

Recent News from Science Daily …
- This new 3D chip could break AI’s biggest...on December 24, 2025 at 6:21 am
Researchers have created a new kind of 3D computer chip that stacks memory and computing elements vertically, dramatically speeding up how data moves inside the chip. Unlike traditional flat designs, this approach avoids the traffic jams that limit today’s AI hardware. The prototype already beats comparable chips by several times, with future versions expected to go much further. Just as important, it was manufactured entirely in a U.S. foundry, showing the technology is ready for real-world […]
- AI detects cancer but it’s also reading who you...on December 18, 2025 at 4:53 am
AI tools designed to diagnose cancer from tissue samples are quietly learning more than just disease patterns. New research shows these systems can infer patient demographics from pathology slides, leading to biased results for certain groups. The bias stems from how the models are trained and the data they see, not just from missing samples. Researchers also demonstrated a way to significantly reduce these disparities.
- Princeton’s new quantum chip marks a major step...on November 17, 2025 at 6:07 am
A Princeton team built a new tantalum-silicon qubit that survives for over a millisecond, far surpassing today’s best devices. The design tackles surface defects and substrate losses that have limited transmon qubits for years. Easy to integrate into existing quantum chips, the approach could make processors like Google’s vastly more powerful.
- Breakthrough optical processor lets AI compute at...on October 28, 2025 at 1:14 pm
Researchers at Tsinghua University developed the Optical Feature Extraction Engine (OFE2), an optical engine that processes data at 12.5 GHz using light rather than electricity. Its integrated diffraction and data preparation modules enable unprecedented speed and efficiency for AI tasks. Demonstrations in imaging and trading showed improved accuracy, lower latency, and reduced power demand. This innovation pushes optical computing toward real-world, high-performance AI.
- 90% of science is lost. This new AI just found iton October 13, 2025 at 12:46 pm
Vast amounts of valuable research data remain unused, trapped in labs or lost to time. Frontiers aims to change that with FAIR² Data Management, a groundbreaking AI-driven system that makes datasets reusable, verifiable, and citable. By uniting curation, compliance, peer review, and interactive visualization in one platform, FAIR² empowers scientists to share their work responsibly and gain recognition.
