I’m learning about friction and heat. I don’t have an expert understanding, but I think I am learning. I think I understand that force of friction equals the coefficient of friction multiplied by normal force.

The coefficient of friction is a dimensionless number. It represents the number of frictional characteristics of a surface.

Friction converts kinetic energy into heat — which is then transferred between objects due to thermodynamics.

Why should you care? Why do I care?

Gather many types of people into a room and try to solve a problem. Gather people from all walks of life. How easy will it be to create consensus without argument?

Each area of diversity adds to the coefficient of friction in the room. The group will birth a marketplace of ideas as they try to attack the problem. Ideas will be tested, edited, cut, and rebuilt. The winning idea will rise to the top.

The winning idea gets implemented.

Work ships, energy gets transferred.

Change happens.
