What is dust made of? – Michael Marder

View full lesson:

Less than a tenth the size of an ant, a dust mite’s whole world is contained in the dusty film under a bed or in a forgotten corner. This realm is right under our noses, but from our perspective, the tiny specks of brilliant color blend together into a nondescript grey. What are these colorful microscopic particles? Michael Marder explores the science of dust.

Lesson by Michael Marder, animation by Mette Ilene Holmriis.

  • Say a star from another universe blew up, vaporizing everything around it, a very unkown chemical from that universe makes its way to earth, getting past the atmosphere, mixing with one of our chemicals, and blowing up our planet due to them being unique to eachother🤔🤔I want this to be a book

  • From somewhere I remember a quote which says something like "we're all made of stardust". And also, interestingly, in the Bible it is said humans are made from dust and to dust we shall return. Not religious but the coincidence is hard to ignore.

  • Genesis 3:19
    New International Version
    By the sweat of your brow you will eat your food until you return to the ground, since from it you were taken; for dust you are and to dust you will return."
    How did they know this back then?
