  • Tracing the Pulse of the Electron: From Attoseconds to XLEAP

    #2023 W 42 D 2 GMT +08:00. Indicate #75 days to go in 2023. In 2005, the University of Ottawa wondered how fast it was a classical electron made one Bohr orbit in 150 attoseconds. However, the trouble was that to meet the goals of attosecond physics, advances in a single neat extreme ultraviolet pulse…

  • Atten for 18. Atten for Unit. Atten for Attosecond.

    #2023. W 42 D 1 GMT +08:00. Indicate #76 days to go in 2023. Since the beginning of 2010, there has been a study of electrons’ movement in atoms and molecules that are so rapid and measured in attoseconds. An attosecond is a study to represent the time frame it takes for the light to…

  • Operationalizing the Evidence-to-Claim Ladder in STREAM Education

    Learn to distinguish what AI can demonstrate from what we merely assume it understands—and what the evidence actually justifies us in claiming. Product Descriptions Navigating AI Robotics, Epistemic Rigor, and Safety Governance How much can an AI benchmark really prove? When does a correctly cited source fail to support a scientific claim? And how can…

  • Scientific Creativity Begins with Constraints

    Shifting from Fixed Laws to Actionable Boundaries in AI, Physics, and STEAM 2026, version 1.0 Product Description Can limitations make us more creative? Scientific discovery does not happen in a world without boundaries. Every new idea must contend with physical laws, available knowledge, limited resources, and assumptions that can either guide or obstruct progress. Scientific…

  • Beyond the Formula Two Volume Collection

    Product Description Physics is more than remembering equations. Part I explores the science of understanding physics. Part II shows how active learning and conceptual assessment can help develop that understanding. Understand the thinking. Improve the learning. Move beyond the formula. What Readers Will Learn Beyond the Formula — Part I: The Science of Understanding Physics…
