Why the Hardest Rocks Can Be Easy to Break
So, rocks are hard. But the scale we use to rank them, the Mohs scale, is only really good at quantifying that for one kind of hardness, and topaz is a perfect stone to talk about to explain that. And you can check it out in our SciShow...

History's Strangest Beauty Trends
It's impossible to meet the incredibly unrealistic and changing beauty standards of our world, and many of us have already spent way too much time trying to pluck, paint, or contour ourselves into stacking up. It may not be a surprise to...

Cleavage of Carbon-Carbon Bonds With Periodic Acid
Just as important as learning reactions that generate carbon-carbon bonds, we need ways to cleave carbon-carbon bonds as well.This is useful for splitting a molecule up into fragments, or transforming a cyclic molecule into a linear...

Overview of Geologic Structures Part 2: Faults and Folds
We just learned about the different types of rock deformation, so now let's get a closer look at some more specific structures. First we have faults, which can be normal, reverse, and strike-slip or reverse faults. We should also take a...

Stages of Animal Development: Cleavage, Gastrulation, Organogenesis
Before diving into animal diversity, we need a bit more information about animal development, as it will help us understand what we're looking at later. We know that animals reproduce sexually, so a sperm fertilizes an egg to yield a...
