The world is always abuzz with sounds, many of which human ears simply can’t hear. However, other species have extraordinary adaptations that grant them access to realms of sonic extremes. And some of them don’t even have ears— at least,...

To study a system as complex as the entire universe, astrophysicists need to be experts at extracting simple solutions from large data sets. What else could they do with this expertise? In an interdisciplinary talk, TED Fellow and...

A mountain separating two lakes. A room papered floor to ceiling with bridal satins. The lid of an immense snuffbox. These seemingly unrelated images take us on a tour of a sperm whale's head in Herman Melville's "Moby Dick." Though the...

Animals like bats and dolphins navigate the world using echolocation, but there’s also another animal capable of such a feat: humans.

The mirror test is supposed to be a way to figure out when an animal is self-aware, but there might be only one particular animal this test works well on: humans.

Twenty four hundred years ago, Plato, one of history's most famous thinkers, said life is like being chained up in a cave forced to watch shadows flitting across a stone wall. Beyond sounding quite morbid, what exactly did he mean? Alex...

In this Algebra 1 lesson, we will identify the correct vertex form of the given graph of a quadratic function. We dive into Common Core Standard HS.F-BF.3 as we explore how transformations affect functions — specifically...

This video illustrates the sequence that a geometric figure takes through a transformation. Transformations may include translations, reflections, and/or rotations.

In this video, the teacher explains the concepts of reflections and translations using examples of Pentagon L and Triangle T on a coordinate plane. The viewer is presented with multiple choice questions to test their understanding of...

In this video, the teacher explains how to identify the correct statements about a transformation of a triangle on a coordinate plane. The teacher goes through each answer choice and explains why it is either correct or incorrect,...

In this video, a math teacher demonstrates how to solve a standardized test math question involving reflections over the Y axis. The teacher explains the concept and provides step-by-step instructions for finding the image of a point...

👉 Learn how to apply transformations of a figure and on a plane. We will do this by sliding the figure based on the transformation vector or directions of translations. When performing a translation we are sliding a given figure up,...
