Phylum Nematomorpha: Parasitic Horsehair Worms
Very similar to Nematoda is phylum Nematomorpha, or the horsehair worms. This is an entirely parasitic phylum. What is their morphology and life cycle? What is pseudoparasitism? Let's take a look!

Introduction to Verbs in Latin
Переглядів 8 тис.11 годин тому
Let's continue working our way through the parts of speech in Latin. With nouns covered, let's talk about verbs. The inflection for verbs, or conjugation, is very complicated, and dreaded by most students. But don't worry, we aren't going to go too crazy yet, let's just talk about the very basics: person, number, tense, mood, voice, and transitive/intransitive. Let's define these concepts now s...
Eric Dubay Sucks at Life (200 Flat Earth “Proofs” Debunked)

It's been quite some time since I checked in with flat earthers, those pathetic grifters peddling the dumbest hoax in the history of the human species. But I felt compelled to revisit the subject in order to debunk the fraud who is still regarded as some kind of flat earth messiah, Eric Dubay. His ridiculous pamphlet commonly referred to as "200 Flat Earth Proofs" was just a rehashed version of...

Now that we have some information regarding nematodes, or roundworms, it's time to get a closer look at the parasitic variety. Some parasitize plants, some parasitize insects, and some parasitize humans, causing diseases in certain parts of the world.

Word Order in Latin (Syntax)
Переглядів 8 тис.14 днів тому
With some understanding of phonetics and the parts of speech, we are ready to start looking at simple Latin sentences. But this requires discussing the concept of syntax, or word order. Does Latin have rigorous syntax like in English? It does not! Because of the inflection of words, the role of each word in a sentence is known from its form, and the word order is totally irrelevant. Let's see h...
The Anthropoids
Переглядів 8 тис.14 днів тому
Moving along with the history of primates, as we approach the Eocene-Oligocene boundary, we find the anthropoids, sometimes called simiiformes. This group encompasses the lineage of both new and old world monkeys, or platyrrhines and catarrhines. These first evolved in the Fayum of Egypt around 37 million years ago, and there are a few subcategories we are going to look at. Let's get started! S...
Logic in Late Modern Philosophy
Переглядів 9 тис.21 день тому
How did logic continue to develop as the modern period in philosophy progressed? Mill and Comte discussed the inverse deductive method. But then a huge figure arose, George Boole. He innovated new logical symbology that got us closer to reducing logic to pure mathematics. Then Peirce developed abductive or retroductive logic. Let's get a closer look at these figures now!

    Oh my GOD. I could for the life of me not comprehend eigenvectors the way my prof taught us. He taught an overcomplicated way of finding eigenvalues so THAT was a lot to unpack. This is so much easier! This is the FIRST video explication i had to watch in the whole first year of uni... goes to show how overcomplicated it was. Tho for eigenvectors it could've been explained a little bit better because what we do is setting x1 to 1 and removing the first row for Lambda 1. Then setting x1 to 1 and removing 2nd row for Lambda 2 And so on. Tbh i have no idea if it's ok to do it like this but this subject has drained me so much to the point i don't even care anymore

If you haven't seen it, he is on a miles-long straight of this track and it is specifically stated that standing at one end of the straight you can't actually see the other end of the track because it follows the curvature of the Earth.
