How many times do you look in a mirror every day? Have you ever stopped to wonder how they actually work? Mirrors do strange things to our world, seemingly flipping everything so that what was right is left and what was left is right....

This video is about the Ozma problem of distinguishing the chirality (ie left-handedness or...

Scientists picked up two unusual signals that seemed to be coming up from the ground instead of down from space. They're still working on understanding why, but despite what you may have heard, they aren't evidence for a parallel...

Tal Golesworthy is a boiler engineer -- he knows piping and plumbing. When he needed surgery to repair a life-threatening problem with his aorta, he mixed his engineering skills with his doctors' medical knowledge to design a better...

What is a Neutrino?

The shape of molecules is super important to life as we know it. In this episode of Crash Course Organic Chemistry we’re learning about stereochemistry and how to identify molecules as chiral or achiral. And as always, we’ll be doing a...

Improve your understanding of molecular properties with this lesson on the fascinating property of chirality. Your hands are the secret to understanding the strange similarity between two molecules that look almost exactly alike, but are...

This video, entitled "Verify Transformation Type," explains the different types of transformations that can occur with a two-dimensional figure.

What is the origin of mass in the universe? Symmetry breaking. Symmetries in quantum mechanics result in 3 of the fundamental forces of nature - electromagnetic, weak and strong forces. However, the breaking of...

In this video I explain what supersymmetry is, why physicists think it should exist, why we haven't discovered it, and why it is necess

Pupil outcome: I can employ repetition to raise awareness of social issues and amplify underrepresented voices. Key learning points: - Art can bring awareness to social issues from around the world and can be about anything. - Art...

Pupil outcome: I can reflect polygons in a line of symmetry, including when there are no sides parallel to the line of symmetry. Key learning points: - When you reflect a shape, it will be the same distance from the mirror line on both...

Pupil outcome: I can reflect polygons that are dissected (cut in half) by the line of symmetry, and explore the new shapes that are created when a polygon is reflected. Key learning points: - When you reflect a shape, each vertex will be...

Pupil outcome: I can describe how an object has moved or changed. Key learning points: - A congruent shape has not changed size - Two shapes can be congruent even if one has been reflected or rotated - An image can be described in terms...

Pupil outcome: I can understand the nature of rotations and appreciate what changes and what is invariant. Key learning points: - The length of the lines do not change when rotated - The angles inside an object do not change when rotated...

This Video Explains the Mirror Image Rule - Contract Law

TikTok's inversion filter reverses a facial selfie and shows you what your face looks like when its not reflected in a mirror. Or, in other words, how the world sees you and not what the mirror shows. Thus, the effect of this reversal is...

Matter composed of antiparticles. For every particle of ordinary matter there is a corresponding antiparticle which has the same mass but the opposite charge. A Twig Science Glossary Film. Key scientific terms defined in just 60 seconds...

For a molecule to exhibit optical activity, it must be chiral, meaning it has no internal plane of symmetry. Additionally, the solution or compound should not contain equal amounts of enantiomers (racemic mixture), as these cancel out...

Chirality refers to molecules that have a non-superimposable mirror image due to an asymmetric carbon atom. These chiral compounds are vital in many biological systems, as their mirror images often have different effects

Optical isomerism occurs in molecules that are chiral, meaning they cannot be superimposed on their mirror images. These isomers, known as enantiomers, differ in their optical activity—they rotate plane-polarized light in opposite...

Mr. Addit explains the term reflection. He also reflects various plane shapes across the line of symmetry and examines the reflected images.

Mr. Addit explains the line of symmetry, and examines a variety of plane shapes to find lines of symmetry.
