Links to Resources

We think there is an incredible wealth of information freely available on S.T.E.M. topics. Below is a very brief listing of some of the sources that have inspired us and that we think are excellent. We also support and refer to Wikipedia regularly, though we recognize it is crowdsourced and cannot be taken as the ultimate authority on most matters.

We are also raising a daughter who loves to code. At time of writing (early 2021, during the COVID-19 pandemic), the author has come to realize, especially due to COVID, that computers, coding and AI, and all things virtual, will only grow in influence and importance. It's not hard to foresee a world where great coders and technology innovators are more powerful than Prime Ministers, Presidents, and other World Leaders. Perhaps Bill Gates is already there at time of writing (2021), and of course, Elon Musk. Perhaps others. Resistance is futile.

Also, the author will sleep at night believing that this online store, and learning about physics, chemistry, etc. is in fact very simpatico with coding - electromagnetic signals interact with silicon in an almost miraculous way at the transistor level, and it's been unleashing breathtaking creative genius among coders worldwide. Have you seen the graphics in A-list games these days !?! It's almost getting better than reality.

So we've reorganized the list to include coding-related links FIRST (including generally "math" related sites), and the "physical" sciences (and everything else) SECOND. Sites that include some of each are in the FIRST grouping. Within each list, most items are ordered chronologically by when we first became aware of the item.

Our lists below will always be incomplete. Please feel free to email us your favourites and we'll be happy to add them below.

1. Coding and Virtual Sites

Kid's Online Learning Tools for Science, Technology and Beyond.  This site was suggested to us and contains links to tons of Science Fair Project ideas to explore, STEM Activities for Kids, and coding and programming resources for all ages. An awesome (and free) source if you want to build your own electronics, Internet of Things (IoT) device, drones and/or robots.
