Voltage is simply electric potential difference and if you have a buildup of potential in one electrode through buildup of H+ ions, you can expect the measurement for potential energy difference between one electrode and the other to be higher.

>> No.12273067

hmm, every molecule in the solution is a staticy balloon, what happens if touch balloon? zap zap.

adding H+ is like rubbing some balloons with wooley feet, more static per molecule, when they touch potentio meter they go zap zap and it moves

Dot products increase when the two vectors are more similar, decrease (into the negatives) when they are more dissimilar (ie: when the arrow in k space is pointed the opposite direction.).

So this is the set of all vectors x that are less similar to vector p than some measure, B.

In a space visualization, this would draw a decision boundary (set by B) as some hyperplane cutting through k dimensional space. If vector x lies on one side of the boundary, it's in the set A; on the other side, it's not on the set A.

The number of such possible vectors is infinite, this it's an open set.

>when we are successful $ will be a successful byproduct
>Our goal is to fundraise soon but in the beginning the salaries will be slightly below market rates
The moment someone offers a job with the promise that they MIGHT pay you eventually if it works out, that is the moment you instantly jump ship. There is zero reason to ever bother with any this type of startup. There is no point in even trying to entertain the idea.
>Who need consistent direction + mentorship + need to be told what to do + how to do it
So they want to hire an army of interns but at the same time they want a highly professional team of experts that will instantly know what to do.
>Someone who is willing to live the 'ramen + instant coffee' lifestyle for a bit before we raise venture capital
You could probably earn more as a hobo begging for cash in front of the supermarket in the middle of a pandemic than what you would be getting from a job like this.
>Someone who is deeply passionate about the intersection of climate change + fashion + apparel
>A Doctorate or atleast a Masters in either Materials Science & Engineering, Fiber & Polymer Science, Chemical Engineering, Electrical Engineering, Chemistry, Physics or the like
>lab-based experimantal roles
So this is a female fashion designer (which is a term I use generously here since she has no clue that nobody wants to wear polyester clothing) that wants to make eco-friendly clothing with inbuilt circuitry with the cheapest polyester clothing imaginable. And she wants it developed by experimentation (meaning she isn't an ideas person since she doesn't even have an idea yet), created from scratch using raw crude oil and she wants it done in a environment-conscious manner.

Are there any advantages of being bilingual beside being able to communicate with more people? Most anglo-countries are monolingual, and they are doing quite well.

People from Switzerland and Luxembourg are usally trilingual, and they have the highest HDI in the world. However, you can probably find many examples that prove the exact opposite also. People in India usually speak many language, but it doesn't seem to be of any advantages to them. The examples I gave are extremely binary, and there are other variables to take into account of course.
