First Year At QED Insight

Today marks the first anniversary of the beginning of this blog, and I’d like to thank everyone who dropped by. It’s been fun, and I’ll continue in the new year.

Of the 125 posts at this blog in the past year, the most frequently viewed have been:

  1. When a metal ring is heated, does the hole expand, contract, or stay the same size?
  2. An Operator Method for Solving Second Order Differential Equations
  3. Peering Into An Eagle’s Nest: Raptor Resource Project
  4. “The Coconut Problem”; Updated With Solution
  5. An Operator Method for Solving Second Order Differential Equations, Part 2
  6. The Field Concept in Physics
  7. Puzzle: A Cube Of Resistors, Updated With Links To Solutions
  8. The Disney World of Good vs. Evil
  9. Why Radian Measure Makes Life Easier In Mathematics And Physics
  10. The Logic Puzzles Of Raymond Smullyan; Updated With Solution
  11. A Practical Use For Logarithms, Part 2: How We Multiplied Large Numbers 40 Years Ago, And How Integral Transforms Use The Same Basic Idea
  12. Why Does A Propane Torch Get Cold When Used? Updated, With Refrigerators
  13. Teaching Critical Thinking: An Example From Electricity And Magnetism
  14. On teaching how to prove mathematics theorems
  15. How To Read A Mathematics Textbook

I’ll be updating the resource pages and blog links soon; doing this regularly will (I hope) make them increasingly useful.

Blessings to everyone for good health and a great new year!

About Santo D'Agostino

I have taught mathematics and physics since the mid 1980s. I have also been a textbook writer/editor since then. Currently I am working independently on a number of writing and education projects while teaching physics at my local university. I love math and physics, and love teaching and writing about them. My blog also discusses education, science, environment, etc. Further resources, and online tutoring, can be found at my other site
