Paul Andersen describes how free energy is used by organisms to grow, maintain order, and reproduce. A brief discussion of the first and second law of thermodynamics is also included. Disruptions in the amount of free energy can cause...

In this video Paul Andersen explains how you can use the Gibbs Free Energy equation to determine if a process is spontaneous or not spontaneous. If the _G is less than zero the process is spontaneous. If the _G is greater than zero the...

Blank and Free Verse are sometimes confused as being interchangeable, but they aren't! Also, we sometimes believe we're writing in Free Verse, but we're actually denying ourselves credit we deserve.

We know that the free energy change associated with a process will tell us whether it is spontaneous or not. And we also know that this depends on the change in enthalpy and the change in entropy for that process, as well as the...

Imagine if heating and powering homes became free in the next decade. What would that mean for the world?

Free Energy Functions: A Physiological Perspective

Free Verse Poetry reviews the elements of a free verse poem and composes one of at least five lines about a famous person in history.

We know that a lot of thermodynamic data is collected under standard conditions, but sometimes we will want to assess the free energy change associated with a process that is not occurring under standard conditions. Any other conditions...

Imagine a world in which electricity was free. Heating and powering homes for nothing would bring obvious benefits, but there would be downsides too.

This video is about Free Verse poetry and Walt Whitman.

Mercy me, how are cell potential, equilibrium constants, and free energy change all related? By a few different equations, that's how. See if you can solve for these values given some data!

In this video Paul Andersen explains how free-body diagrams can be used to solve kinematics problems. The only two parts of a free-body diagram are the object and all external forces acting on the object. Numerous situations are...

Do we really have free will? Today Hank explores possible answers to that question, explaining theories like libertarian free will and it’s counterpoint, hard determinism.

Physicists have a long history of sticking our noses where they don’t belong - and one of our favorite places to step beyond our expertise is the question of consciousness and free will. Sometimes our musings are insightful, sometimes...

Telegram founder Pavel Durov, a self-proclaimed free speech absolutist, faces scrutiny as his platform navigates the complexities of enabling open communication while addressing criminal misuse, including child sexual abuse material....

Without the internet, how would you have coped with the pandemic -- from work and school, to maintaining your closest relationships? In the digital age, reliance on the internet is so common and seems ubiquitous, yet billions of people...

Many people are looking for ways to reduce their consumption of animal products. And these days, there are a ton of plant-based alternatives to help them do that. But many companies are working on ways to make animal-free animal products...

Mr. Andersen shows you how to draw free body diagrams of various objects. The major forces (like gravity, normal, tension, friction, air resistance, etc.) are discussed and then applied to various problems.

Too many people believe in something closer to freedom from speech rather than freedom of speech, says attorney Greg Lukianoff. In a timely talk, he warns against the rise of "mob censorship" — and reminds us why free speech is the best...

Paul Andersen attempts to explain Gibbs Free Energy. He begins by using three spontaneous reactions to explain how a change in enthalpy, entropy and temperature can affect the free energy of a system. He then applies this concept to...

In this video Paul Andersen explains how thermodynamic and equilibrium reasoning can be related through changes in free energy and the equilibrium constant. When the delta G is negative the reaction shifts to the right or favors...

The simplest definition of free will is the ability to have made a different choice. Our more precise definition: it is the ability of conscious beings to make choices that are not solely determined by prior physical...

What do you like doing in your free time? Do you have any interesting hobbies? Talking about free time and hobbies is a good way to start a conversation in English, or find things in common when you speak to others in...

This video covers: - What a resultant force is - What free body diagrams are - How to calculate the resultant force from a free body diagram - The idea of splitting up the forces into horizontal and vertical components General info: -...
