Ok look, you don't have to be negative about it!

Maybe your attitude is the reason your body is falling apart?

Saying fascists have lost Joe Rogan's support is like saying that your dog has lost all interest in playing with tennis balls forever because they got distracted by something else, just wait 5 minutes and things will reset.

You asked "how do you know that" and I answered you.

It is very simple.

  1. Electric engines are far more efficient than fossil fuel engines.

  2. The generation of electricity from a large powerplant to charge an Electric Aircraft's batteries whether a fossil fuel powerplant or a sustainable energy one is going to be an order of magnitude more efficient than converting fossil fuels into energy in a minipowerplant on the airplane. This is a simple consequence of the efficiency of scale.

  3. Electric Aircraft can maximally reduce the cost of energy by charging when the grid is oversupplied with electricity, this provides a capability to trade waiting time for reduced energy footprint/grid impact and in many situations the energy stored in an Electric Aircraft's batteries that can be used to then accomplish real work might have simply gone to waste if there hadn't been another battery hooked up to the grid.

  4. The production of aviation fuel in particular is costly and energy intensive requiring discrete production infrastructure whereas the charging of a battery for an electric aircraft just takes normal old electrons like any old battery.

If the cost of using an Electric Aircraft is minimal, than comparing it to fossil fuel powered Aircraft isn't really relevant since the fossil fuel powered Aircraft is going to use far more energy and resources to accomplish the same amount of work.

That doesn't mean there aren't drawbacks to Electric Aircraft, but one of their undeniable advantages is that they are far less wasteful with energy use than normal Aircraft in a way that is difficult to compare directly with simple numbers.

How do you value alternative electricity production that is going to waste?

That is a question with a manifold of implications and it makes your question far more difficult to parse than you realize.

I don't like Harris but Biden was far less competent and suited to the moment.

Obama's biggest mistake was playing it safe with a DEI hire for an ideologically bankrupt, incompetent old white guy for his VP.

Harris doesn't have charisma with normal people (though she is apparently great at getting fundraising from the rich and powerful..) but at least she showed some kind of awareness of how to play politics unlike Biden who stumbled through his presidency and failed campaign for re-election like a dementia patient sleepwalking out onto a busy highway.

Around a decade ago, Semyon Dyatlov(opens a new tab), a mathematician at the Massachusetts Institute of Technology, was studying whether quantum particles behave differently than ordinary particles when put into the same chaotic situations. Sometimes, an object moving chaotically can become trapped into following a fractal-like path forever. Could quantum particles do the same?

Quantum particles tend to spread out like waves, which blurs their exact location. To figure out whether quantum particles blur too much to take on these intricate trapped paths, Dyatlov needed a new uncertainty principle — one that could tackle fractals.

In 2016, with key ideas from Jean Bourgain — a renowned mathematician who died shortly after this work — Dyatlov proved the fractal uncertainty principle for one-dimensional fractals, which look like jagged lines. These lines can represent the paths taken by objects moving in two dimensions, like balls traveling around a billiard table. That fall, Dyatlov and Bourgain gathered mathematicians from around the world in New Jersey for a workshop, hoping to extend the proof to higher dimensions. An extended proof could be used to study the three-dimensional world and would become a universal mathematical tool in its own right.

...

It wasn’t until years later that Alex Cohen(opens a new tab), while a doctoral student at MIT, finally made a breakthrough. In a paper(opens a new tab) published in 2025 in the Annals of Mathematics, widely considered to be the field’s top journal, he extended the fractal uncertainty principle to all higher dimensions. The result became Cohen’s thesis and earned him an assistant professorship at New York University at the age of 25.

*Opportunistic Ethnic Cleansing NOT Famine.

There was absolutely enough food being grown in Ireland for the Irish, just not enough to make England feel empathy for the starving Irish who had to sell all of the food that did grow to England in order to "survive".

That is also what innocent people who have had their lives shattered and obliterated by these machines were likely screaming through tears and terror as they were beaten and violently forced into the back of an unmarked SUV by thugs with machine guns.

Remember NONE of this was really ever about making money or good art.

This is a product of a cancerous and pseudo-spiritual ideology in the ruling class that the working class are fundamentally only temporarily useful.

Why do I keep getting the feeling that the Dolphins keep trying to use tools and props to warn us Earth is about to be demolished for a hyperspace bypass?

How is that relevant? It is WAY higher.

Neighbourhoods across the United States that experienced a growth in their undocumented population also saw property-related and violent crime fall, not rise, according to an analysis of 11,500 neighbourhoods in more than 100 cities.

In a paper published in the Journal of Urban Affairs on 10 August1, researchers combined estimates of numbers of undocumented residents with crime statistics from between 2010 and 2018.

“Our study is the first to analyse these numbers across neighbourhoods and using such a diverse national sample,” says co-author Charis Kubrin, a criminologist at the University of California, Irvine. “That’s important because neighbourhoods are very proximate spaces to people. That’s where perceptions form.”

Meanwhile US mainstream media is obsessed with scaremongering about Hasan Piker who says the US needs socialism to root out a lack of access to healthcare.
