We often think learning is about intense concentration—hitting the books hard, drilling through problems until something clicks. That’s only half the picture. Our brains operate in two distinct modes: focused and diffuse. The focused mode is active concentration—what happens when you’re solving a p...

From A Mind for Numbers: How to Excel at Math and Science (Even If You Flunked Algebra)

Learning doesn’t happen in a flood of information. It occurs in chunks—discrete, interconnected pieces of knowledge that our brains compress into compact, usable patterns. When you practice a concept until it becomes familiar, your neurons form links that represent that idea as a unit. That’s chunki...

From A Mind for Numbers: How to Excel at Math and Science (Even If You Flunked Algebra)

Learning is not about keeping your mind in an unbroken state of concentration. The human brain actually learns most effectively by alternating between two distinct modes. The focused mode feels familiar — it’s what we experience when we’re consciously solving a problem, reading intently, or practici...

From Learn Like a Pro: Science-Based Techniques to Accelerate Your Learning

We often assume that repeating information in a short burst cements it in memory. In truth, memory is strengthened not by repetition alone, but by time and struggle. One of the cornerstones of learning science that we present in *Learn Like a Pro* is spaced repetition — revisiting material at increa...

From Learn Like a Pro: Science-Based Techniques to Accelerate Your Learning

Every learner experiences two complementary modes of thinking: the focused mode and the diffuse mode. The focused mode is deliberate and analytical — like looking through a microscope, zeroing in on a single concept or problem. This is the mode we enter when we solve equations, memorize vocabulary, ...

From Uncommon Sense Teaching: Practical Insights in Brain Science to Help Students Learn

Working memory is remarkably limited. Neuroscientist Terrence Sejnowski often likens it to a mental scratchpad, holding only a few items at once. Without conscious reinforcement, most information written there disappears within seconds. Long-term memory, in contrast, functions like a vast warehouse ...
