electric potential is analogous to gravitational potential energy, but with electrostatics!

\begin{equation} P_{E} = qV \end{equation}

where \(q\) is the change on the particle in question, and \(V\) is the voltage, the difference in electric potential between two places.

Yes, voltage is defined vis a vi electric potential: that is, it represents a differential of electric potential.

additional information

electric potential is analogous to gravitational potential

Let \(A, B, C\) be positrons, and the lines are the electric field. Which one has the highest electric potential? \(A\), because it has the most distance to travel to until it can get all the way to the right.

Mathematical Systems

• Systemic influences with various pieces
• Hopfield Networks

Mouse Video Games

Derivatives are essentially a high pass filter

Methods of neuro imaging

• calcium channel florescence
• Electrode measurements
• Optogenetics

primary methods

• analyzing monke with neuro-imaging methods above
• creating in silico models based on those responses, in a large systems of differential equations
• play with those equations to figure possible novel responses
• try them on monke

For matrix \(A\), we want to make a series of matrix \(M\) which will zero columns out. This is a algorithms approach for doing this, which is also applied columnwise.

nicely, we can undo our operations

and you can compose them by subtracting together

*THIS IS ONLY TRUE when we are applying in the right ordering, row \(1\) to row \(2\), etc.

pivoting

this procedure breaks on:

Wizenbaum (1966)

works pattern-action rules by rephrasing user’s questions

“You hate me” => “what makes you think I hate you”

Rogerian psycotherapy: assume no real-world knowledge; simply draws out patient’s statements

I need X => what would it mean to you if you got X.

uses regex

capture specific adjectives, “all”, “always”, etc. and responds accordingly

Eliza Rules

patterns are organized by keywords: a keyword has a pattern and a list of transforms:
