## What is a dimension? In 3D…and 2D… and 1D

Minute Physics provides an energetic and entertaining view of old and new problems in physics — all in a minute! In this episode we talk about dimensions and how we know that we live in 3D (or do we?)

## 8.01x – Lect 11 – Work, Kinetic & Potential Energy, Gravitation, Conservative Forces

Content : Work – Kinetic Energy – Potential Energy – Newton’s Universal Law of Gravitation

## Tutorial: creating the sound of hydrogen

Minute Physics provides an energetic and entertaining view of old and new problems in physics — all in a minute! In this tutorial I show how I synthesized the sound of hydrogen for the “Sound of Hydrogen” video using mathematica – it’s a little technical, but you’ve been requesting it! Created by Henry Reich

## Adding Past Infinity

Minute Physics provides an energetic and entertaining view of old and new problems in physics — all in a minute! In this episode we take a break from physics and do a little fuzzy math. But not really: this is actually relevant to physics! Come back and I’ll explain later. Created by Henry Reich

## What is Quantum Tunneling?

Minute Physics provides an energetic and entertaining view of old and new problems in physics — all in a minute! In this episode we explain what quantum tunneling is and how it works!

## The Sound of Hydrogen

Minute Physics provides an energetic and entertaining view of old and new problems in physics — all in a minute! This episode is a little bit different from the norm, because I’ve created the sound of hydrogen – or, that is, what if it would sound like if it emitted sound instead of light waves! Created by Henry Reich

## What is the Uncertainty Principle?

Minute Physics provides an energetic and entertaining view of old and new problems in physics — all in a minute! In this episode, we talk about the Heisenberg uncertainty principle and how it’s not really that weird – it’s just a property of waves!

## How the Sun works: Fusion and Quantum Tunneling

Minute Physics provides an energetic and entertaining view of old and new problems in physics — all in a minute! In this episode, we learn about how the sun can burn for billions of years without running out of fuel.

## The First & Zeroth Laws of Thermodynamics

we’ll explore thermodynamics and some of the ways it shows up in our daily lives. We’ll learn the zeroth law of thermodynamics, what it means to reach a thermal equilibrium, and define the first law of thermodynamics. We’ll also explore how stationary, adiabatic, and isochoric processes can make our lives as engineers a little easier. Note: Different branches of engineering sometimes define the first law of thermodynamics differently, depending on how work is defined. Essentially, work released from a system might be defined as a positive value or a negative value, and thus the first law can be defined as either Q-W or Q+W. Both are acceptable forms, depending on how the system is defined! We chose to focus on only one definition here to limit the confusion.

## The Law of Conservation

We’ll discuss conversion and yield, accumulation, and how generation and consumption can affect how much accumulation there is in a system.

## What is the Wave/ Particle Duality?

Minute Physics provides an energetic and entertaining view of old and new problems in physics — all in a minute! In this episode, we discuss the Wave Particle Duality and why quantum mechanics is weirder than anything we’re used to in our daily lives! Minute Physics provides an energetic and entertaining view of old and new problems in physics — all in a minute! In this episode, we discuss the Wave Particle Duality and why quantum mechanics is weirder than anything we’re used to in our daily lives!

In this episode, I revisit the wave particle duality and present an intuitive analogy for understanding how it works.

## What is Dark Matter?

Minute Physics provides an energetic and entertaining view of old and new problems in physics — all in one minute!

In this episode, we discuss Dark Matter, an exotic type of matter we know very little about, despite the fact that it makes up around 80% of all matter in the universe!

## what is Gravity?

One Minute Physics provides an energetic and entertaining view of old and new problems in physics — all in one minute!

In this episode, we discuss the basic nature of gravity, one of the four fundamental forces in our universe.
