  • Therefore i¹⁰ = ln(-1)¹⁰/pi¹⁰ = -1

    This is true but does not follow from the preceding steps, specifically finding it to be equal to -1. You can obviously find it from i²=-1 but they didn’t show that. I think they tried to equivocate this expression with the answer for e which you can’t do, it doesn’t follow because e and i¹⁰ = ln(-1)¹⁰/pi¹⁰ are different expressions and without external proof, could have different values.



  • God I remember that fucking bullshit about the Chinese photographer/artist who made a piece dramatizing the crimes of Australia in Afghanistan.

    The Australian flag draped over the Afghan flag shaped as a puzzle piece on the floor.

    And the narrative the Australian media went with was “this is fake news, the image is fake.” Uh, yeah? That’s how art works, it’s not supposed to fool. Quit fucking distracting from the discussion about the crimes of Australia






  • 100% clean no, but 100% renewable is theoretically possible.

    If the electric grid entirely eliminates fossil sources of energy, and the supply chain electrifies, and if the extraction equipment electrifies, and if the storage facilities are run off non-fossil fuel energy, and the manufacturing facilities, and everyone involved didn’t consume or use cattle products because of their methane emissions, and all buildings are wooden construction, and all polymers are plant-based, etc etc, then one could say a company uses 100% renewable energy.

    But for practicality’s sake, 0% fossil fuel-generated electricity and heating is a good metric to call “100% renewable” for most things. If a manufacturing process inherently produces GHGs like portland cement concrete, you can adjust the definition appropriately.

    And yes cap and trade strategies and whatever else are bs

    Actual explanation

    “Subject alternately fixates on each of two proffered snacks, before choosing one. [The image shows the] average path of the decision variable according to the Krajbich model for three parameter settings. The decision variable ramps toward the left or right choice boundaries, with the slope determined by the true relative subjective value of the items (here, left is preferred), but biased to slope toward the item currently being fixated. The biases depicted are: high (green), medium (red, as actually inferred from the data) or none (blue). Clocks depict the excess time spent looking at the left versus the right option at each step.”

    TL;DR The leaning of the decision-maker is influenced by which choice they’re currently looking at, getting stronger with time, until a threshold is reached where the decision is made. A more eye-catching item is therefore more likely to be chosen because it gets more sight-time.

    Link to article. Although technically OP’s image is from a paper that yoinked the left half of the figure to waffle on about some economics bs. But this is the original source.
