“Journey to the Center of the Earth” is a curated collection of articles published by the Smithsonian magazine. As you scroll down the page, you move deeper into the Earth — a thermometer and a depth gauge keep track of how far down the page you’ve scrolled. At each division (surface, crust, mantle, outer core, inner core), you’re given a selection of pieces about that layer as well as quick facts about the materials and physics which can be found at that depth.
It’s a lot to take in, but it’s very interesting!
This is a super-useful tool for quick calculations and graphs. Try entering something like “surface area of sun”, “pi to 100 digits”, “life expectancy france 1910”, or “Who formulated the halting problem?” in the search bar!
This website looks like a regular search engine, but returns facts, figures, and charts, rather than just URLs to other pages.
Here’s a cool subreddit where people ask STEM-related questions like:
“If you fired a handgun from the ISS, pointing away from Earth, would it be able to escape Earth’s gravitational pull?”
“What is the advantage of having five, rather than four or six, fingers?”
“How is information encoded between the eye and the brain?”
…some questions on this board are pretty easily answered, but others provoke long, interesting discussions! Usually these questions are answered by people who have some professional knowledge of the topic on which they’re commenting.
“Founded in 2002 by Nobel Laureate Carl Wieman, the PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations. PhET sims are based on extensive education research and engage students through an intuitive, game-like environment where students learn through exploration and discovery.”
Hyperphysics is an extensive resource for many subfields of physics. Topics usually include a brief introduction and thorough description, the basic relevant formulas, and links to related topics.
