How Everything in Physics Fits Together – Map

Unless you have an innate knowledge of physics, it’s pretty hard to figure out how all the concepts and theories fit together

Physics is a huge, complex field. It also happens to be one of the most fascinating, dealing with everything from black holes and wormholes to quantum teleportation and gravitational waves.

But unless you have an innate knowledge of the field, it’s pretty hard to figure out how all these concepts actually fit together.

After all, everyone is constantly trying to prove Einstein wrong, and Stephen Hawking famously struggled to come up with a ‘theory of everything’, so it’s easy to get confused about how things do actually fit together in physics (if at all).

YouTuber Dominic Walliman has created a map that shows how the many branches of physics link together, from the earliest days of classical physics and Isaac Newton, all the way through to Einstein’s relativity and quantum physics (with a little bit of philosophy thrown in there for good measure).

The Brain Dictionary

Where exactly are the words in your head?

Functional magnetic resonance imaging (fMRI) was used to measure brain activity in seven people while they listened to more than 2 hours of stories from The Moth Radio Hour. This data was used to estimate voxel-wise models that predict brain activity in each voxel (volumetric pixel) based on the meaning of the words in the stories. Read the paper describing this research here.

Scientists have created an interactive map showing which brain areas respond to hearing different words. The map reveals how language is spread throughout the cortex and across both hemispheres, showing groups of words clustered together by meaning. The beautiful interactive model allows us to explore the complex organisation of the enormous dictionaries in our heads.
