What do sandwiches have to do with AI? Data reformist Kasia Chmielinski helps us think about artificial intelligence with a useful food metaphor — and breaks down why AI systems should have "nutrition labels" to ensure the development of...

The impact of the baby boom generation is impossible to ignore. The roughly 76 million people born between 1946 and 1964 have reshaped American society at each stage of their lives. Philip Bump of The Washington Post takes a closer look...

In this video Paul Andersen explains how contour lines show areas of equal elevation or equal gravitational potential. Contour lines are used as an analogy for lines of equipotential in electric fields.

One of the most significant scientific discoveries of the early 21st century is surely the Higgs boson, but the boson and the Higgs Field that allows for that magic particle are extremely difficult to grasp. Don Lincoln outlines an...

It's 1997. The United States Senate has called a hearing about global warming. Some expert witnesses point out that past periods in Earth's history were warmer than the 20th century. Because such variations existed long before humans,...

In this video Paul Andersen explains how the average value of the electric field can be determined by dividing the potential difference by the displacement. Equipotential lines can be used to determine the potential in an electric field...

Last week we introduced Thomas Aquinas’s four cosmological arguments for the existence of god; today we introduce his fifth argument: the teleological argument, and the ensuing dialogue it initiated.

Paul Andersen explains the concept of coevolution. He begins with an analogy comparing the relationship of humans to technology with those of coevolving species. He then discriminates between coevolution and convergent evolution. He...

We’re picking up where we left off last time, exploring the “ethics of care” and how it applies to extreme poverty. Are we responding to global poverty in a moral way? Philosophers like Peter Singer argue that we have an obligation to...

Mr. Andersen describes the relationship between voltage, current and resistance in an electric circuit. Ohm's Law is introduced through a circuit simulation.

Mr. Andersen shows you how to use the factor label method to solve complex conversions.

In this video Paul Andersen explains why the slowest elementary step in a chemical reaction is the rate-limiting step. This step can be used to determine the overall rate law of the chemical reaction.

Join Jessi this week at the fort and learn about the unexpectedly awesome organism that's made up of two living things: LICHEN!

In this video Paul Andersen explains how elements and molecules are made of atoms. In a pure sample of a pure substance the average mass remains the same. If more than one atom is found in a molecule the ration of average masses...

This video, entitled "Connections," explains what analogies are and how to use them.

Pupil outcome: I can analyse the dream settings in ‘Jekyll and Hyde’. Key learning points: - Mr. Utterson’s dream is full of images of evil and violence. - Stevenson writes the dream sequence in quick moving prose to mimic the shifting...

Pupil outcome: I can use context to explain the complicity of other characters in the actions of Hyde. Key learning points: - Whilst Jekyll is clearly culpable for the creation of Hyde, arguably others are complicit in his crimes. - Dr....
