IIRC the highly diffractive nature of the medium limits resolution to something like 1 cm^3. I’m not an expert but I talked with some people working in the field a few years ago and this is what I remember. The computational problem is almo

Resistance is inherently dissipative, so there is no coherent path the electron can take. No quantum effects here, the electron is always interacting with the resistor lattice.

Not sure if that’s because I’m not a native speaker, but unless I make a conscious and quite tiresome effort to listen to the lyrics, the human voice is just another instrument among many.

I’m also talking about personal use. These are research devices for my PhD. I’m obviously not paying out of pocket, but my funding agency does. I’m trying to convey that if a tool increases your efficiency by more than it costs then it’s wo

I work in a cleanroom to fabricate semiconductor devices and I spend hundreds of euros per hour to use specific tools which mostly just use electricity and maintenance. Should we complain that it’s too expensive or should we use them becaus

I use qwerty-fr [0] for this. It's pretty nice, since it works on all three major OSes and is basically a few compose layers on top of a US base layout. I use it to type greek letters, swedish vowels, italian accents and math symbols.

Trapped-ion and neutral-atom QC require lasers because the light signal needs to be coherent. That's the main feature of a classical laser, really. The explanation with the number of photons doesn't really cut it, because even a p

This is a laser controlled device. Even the terminology of "interconnect" is not really applicable. Your best hope is an optical waveguide coupled to the device, definitely not a metal line. It's not even a transistor in the

This is an optical transistor, meaning that a current is controlled with an optical pulse. That means that you can't pipe these things into each other, unless you can build an equivalently fast and efficient light->charge transducer

Of course some works are indeed genuinely good ideas. But sometimes things just don’t work out quite as well. Many nature papers in my field are dead ends applications-wise. I’m not saying any of those works specifically are, just that rese

Don’t give too much importance to individual papers. At best, you’re mostly disregarding all the work that lead to it. At worst, you’re placing a lot of faith on an idea analyzed through rose-tinted glasses and presented with a lot of inten

How would you explain when these predictions then turn out to be right? People who are this skilled at reading others are rare, but they do exist.

Well, 2^53 milliseconds is indeed 285 414 years.

Well, maybe they’re not printed by yourself. But many academics, often young people included, still print papers.

I wonder if you could make deployment / installation even cheaper by making big “rolls” of panels and unfolding them directly on the ground. No ground pillars of any kind. If you built a zigzag pattern into the panel, possibly with som

I appreciate frugality, but a clothesline takes significantly longer to load and unload. It’s not an ideal replacement.

Definitely, if your analog substrate is implementing matrix vector multiplications (one of the most common approaches in this area). Then your differentiation algorithm is the usual backpropagation, which has rank 1 weight updates. With som

Why are you so surprised? We understand how gravity works to an incredible degree of precision, and anyone with a physics degree is able to explain it. You seem to have some misconceptions around physics. If you go through the formal traini

Are you proposing that atoms are organisms and/or that astronomical objects may be organisms? I feel like you are just inflating the meaning of “life” without justifying why. Defining it properly is a very interesting problem, but I th

I keep coming back to this thought. Maybe it’s how I was raised, but knowing that I’m doing something useful to other people / humanity is the entire point. When a machine can do everything better than we can, then what do we derive me

That’s right. Back in the day we used to have only clear and descriptive names, like C and GNU.

Dopamine is not permanent, though. We're talking about long-term synaptic plasticity, not short-term neurotransmitter modulation.

The Roman salute has no direct connection to the Roman Empire. It was largely an invention of the 19th and 20th centuries and was popularized by fascist movements. > The most reasonable criticism is calling it a Roman salute and saying i

I think the misconception you have is that nazism means “WW2 anti-semitism” for you. The education on the topic that we get in many European countries goes deeper than that. Would it be better if they called Elon a fascist? He did the fasci

Great example of how information is sometimes compartmentalized arbitrarily in the brain: I imagine you have never been confused by sentences such as “I’m running at 10 km/h”.

Not really. These are wafer-scale chips, which (as far as I'm aware) were first introduced by Cerebras. Cost reduction for cutting-edge products in the semiconductor industry has historically been driven by 1) reducing transistor size

Your comparison with Conway's Game of Life is interesting, since that's inherently local. More importantly, I'm skeptical towards non-locality because it is an extremely strong assumption with very weak effects: the only plac
