Highlights: posts that did unusually well for the person who wrote them, everything they published at length, each release and new project, and every belief — at most two a day from anyone. Day by day, newest day first; within a day, the people with the most beliefs on this site come first. Nothing else orders it. Show everything instead.
The quoted blocks are what people actually said; a beneath one is the belief those words support, in korrents' wording. Nobody here wrote their own page.

From one piece Sean Carroll: General Relativity, Quantum Mechanics, Black Holes & Aliens | Lex Fridman Podcast #428 2 beliefs, in the piece's order there
-
Their words
I tear my hair out when people who are not physicists accuse physicists, like you say, of losing the plot because they need dark matter and dark energy. I don’t want dark matter and dark energy; I want something much cooler than that. I’ve tried. But you got to listen to the equations and to the data.
-
Their words
I think this is one of the biggest things that physics can help with, and it’s an obvious kind of low-hanging fruit situation where the heat generation, the inefficiency, the waste of existing high-level computers is nowhere near the efficiency of our brains. It’s hilariously worse, and we haven’t tried to optimize that hard on that frontier.

But compute is different. Intelligence is going to be more like energy or something like that, where the only thing that I think makes sense to talk about is, at price X, the world will use this much compute, and at price Y, the world will use this much compute.

Their words
And each major accident, that means global freeze on the nuclear reactor production for at least another 10 years. So that’s what I mean that nuclear industry is politic, not just in terms of technology and not just in terms of radiation, impact on health, but also politically a very, very unreliable option.

-
Their words
Compromise, the advantage of compromise as a resolution mechanism is that it's low energy, but it doesn't lead to truth. And so in things like the height of the ceiling where truth is a noble thing, you shouldn't allow compromise to be used when you can know the truth.

In fact, I would say it’s more surprising that the matter that we know about is constitutes as big a fraction of the universe as it does. We’re limited, we’re human. The fact that we see 5% of the energy density of the universe, about one sixth of the energy density in matter, that’s remarkable.

Physicists actively want the standard model to break down, because only the deviations can tell us what underlies it.Their words
One of the things we do as physicists is we actually want it to break down at some level, we’re looking for the precision measurement or the energy or whatever it will take where the standard model is no longer working. Not that it’s not working approximately, but we’re looking for the deviations.

The terrorist attacks on 9/11 killed 2996 people in a day of singular horror. Our ongoing indifference to regulatory inefficiency, considering only the area of green energy development, kills more people every year – more than 10 people per day, and that’s only within the US.

The logical end state of this displacement is not some hybrid grid with around 20% solar backed up by spinning generation, but a much more dynamic, versatile grid with around 200% solar generation and hours to days or weeks of battery storage, fully decoupling time of generation and consumption.

the electric technology used for cars only has to beat energy hogs that are below 10% in efficiency, our everyday car. But to qualify for aircraft use, the technology has to equal or beat what is used today, which is at the 30% to 40% efficiency level using modern turboprop or turbofan engines.

From one piece Does energy imbalance (calories in > out) cause obesity? 3 beliefs, in the piece's order there

No matter what your model of obesity is, in order to explain the development of an obese body, energy imbalance has to be a link in the model’s causal chain.

And beyond that, by the time solar scale has doubled 4 more times, to the equivalent of 16% of today’s electricity demand (and somewhat less of future demand), we should see solar at 3 cents per kwh in the sunniest areas, and 4.5 cents per kwh in moderately sunny areas.
Their words now
Both of those forecasts were wrong. Solar has plunged in price faster than anyone – including me – predicted.

From one piece Sustainable Energy — without the hot air 5 beliefs, in the piece's order there
-
Their words
While wave power may be useful for small communities on remote islands, I suspect it can’t play a significant role in the solution to Britain’s sustainable energy problem.
-
Their words
Just like Britain, Europe can’t live on its own renewables. So if the aim is to get off fossil fuels, Europe needs nuclear power, or solar power in other people’s deserts (as discussed on p179), or both.

So to fix climate change, we need to sort out a new way of getting energy. The climate problem is mostly an energy problem.

For most materials, the embodied energy per unit weight is greater than or equal to 10 kWh per kg – the same as the energy per unit weight of fossil fuels.

planes are already almost as energy-efficient as they could possibly be. Planes unavoidably have to use energy for two reasons: they have to throw air down in order to stay up, and they need energy to overcome air resistance. No redesign of a plane is going to radically improve its efficiency.

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.
