On Conoids and Spheroids

On Conoids and Spheroids (Ancient Greek: Περὶ κωνοειδέων καὶ σφαιροειδέων) is a surviving work by the Greek mathematician and engineer Archimedes (c. 287 BC – c. 212 BC). Consisting of 32 propositions, the work explores properties of and theorems related to the solids generated by revolution of conic sections about their axes, including paraboloids, hyperboloids, and spheroids. The principal result of the work is comparing the volume of any segment cut off by a plane with the volume of a cone with equal base and axis. The work is addressed to Dositheus of Pelusium.

Sphericon—The Shape That Meanders Instead of Rolls

In this video I show you the sphericon and talk about how it works. I also show you a homemade version of the sphericon you can make at home using coins. Hexagonal Sphericon STL: https://www.thingiverse.com/thing:2999598 Original Sphericon STL: https://www.thingiverse.com/thing:3013544 M

Types of Plant Cells

If we want to learn about plant structure and function, we have to start with the smallest components, and those would be plant cells. Just like animals, plants are made of eukaryotic cells of different types, and in plants these are called meristematic cells, parenchyma cells, collenchyma

Types of Silicates Part 2: Inosilicates, Phyllosilicates, and Tectosilicates

In the previous tutorial we learned about some types of silicates, so now let's learn about the rest. That will be inosilicates, phyllosilicates, and tectosilicates. These can get pretty complicated so let's take a closer look! Script by Jared Matteucci and Bryne Hadnott Watch the whole

Phylum Rotifera Part 1: General Characteristics

It's time to wrap up our study of Gnathifera, and this means investigating phylum Rotifera. These are the wheel animals, and we will need a few tutorials to get through them all. Some species are free-living and some are parasitic, and you've probably had some in your body, since they're p

Phylum Rotifera Part 2: Four Major Clades

Now that we understand the general characteristics of phylum Rotifera, let's dig into some of the clades within this phylum. These would be Bdelloidea, Seisonidea, Monogononta, Acanthocephala. Their relationships and phylogeny are still not firmly known, but let's talk about what we do kno
