With an optimistic 10% annual return, this would amount to 1/5 of Cornell's budget.

As a European, I cannot make any sense of the low-contrast pictograms in "modern" software (VS Code, Obsidian, etc.).

They have never demonstrated even a single physical qubit. Microsoft has claimed for a while to have observed some signatures of quantized Majorana conductance which might potentially allow building a qubit in the future. However, other res

The recession due to COVID made it pretty much impossible for an incumbent party to win an election in 2024.

The VSCode agent is so bloated that it tends to OOM raspberrypi pies. Truly remarkable for a piece of software whose job it is to forward some text.

This text is so confidently incorrect, that I have to wonder if it is LLM-generated. The control loop for a frequency comb is actually very simple. Generating the carrier-envelope offset frequency signal is the hard (Nobel prize worthy) par

Frequency combs are optical synthesizers. This means that the frequency of the n th comb mode is exactly n times a radio frequency (+ another radio frequency), where n is a (very large) integer. The speed of light does not matter at all.

Willow has only ~99.7% 2-qubit gate fidelity and poor connectivity. This is many orders of magnitude too low to run Shor's algorithm for a 50-bit number. The improvement has also stalled quite a bit over the last years (in 2019 they ha

I doubt that "land use" is a big issue in one of the least densely populated countries on earth. Surely one could find a place for an industrial site that is not within 5 km of the world's prime telescope site. Using the exis

In the case of MH370, this was most likely intentional, not due to a system failure. Hard to defend against a pilot with a death wish.

I find the wording highly deceptive. The main feature making the internet globally scalable is not that it goes through fibers, but that it uses package routing. Nobody knows how to do this with qubits, so quantum communication doesn't

The gravitational redshift is proportional to the gravitational potential (~1/distance), not to the gravitational acceleration (~1/distance²). This suppresses the effect of small masses nearby a lot compared to the effect of the e

A decent frequency counter can resolve a frequency difference of 1E-15 in a few minutes of averaging. Modern GPS-based frequency comparisons (dual-band, post-processed using precise point positioning) are also accurate to the 1E-15 level wi

Wuhan has a BSL-4 lab since 2018, but it wasn't used for coronavirus research. Most unversity cities have virology groups, and coronaviruses became a popular research subject after SARS, particularly in China. The probability of findin

The report spends 5 pages on COVID origins (re-hashing tired old arguments with zero hard evidence), and 46 pages on shit-talking Andrew Cuomo. Clearly, finding truth was never the objective.

Most countries use way more primary energy for heating and transportation than for electricity generation. It would be disingenuous not to include this.

You can measure the flow of power by calculating the vector product of the current and voltage in the power line. EEVblog has a very good explanation video how this is done in an (analog) domestic watt-hour meter: https://www.you

France has 12% of Europe's population, and its primary energy is 45% from fossil fuels and 40% from nuclear power. The effect on Europe as a whole is therefore pretty small.

According to the IEA [1], 43% of the energy consumption is oil (transportation, heating), 18% is natural gas (mostly heating), and 25% is electricity. Switching to resistive heating would require doubling the electricity production. Using h

It's a very simple explanation why the fire killed his children and not him.

It is undisputed that Willingham's kids slept in the room where the fire broke out, while he slept in a different room. This is a pretty solid explanation for what happened.

This doesn't make any sense. Germany has storage for more than a season's worth of natural gas. The price went up because Russia stopped selling cheap gas to western Europe after its attack on Ukraine.

£54 bn over eight years is around 0.2% of the UK's GDP. A lot of money, but doesn't sound unreasonable for a major overhaul of a central price of infrastructure. Ruling out the possibility of storing energy at industrial scale mig

The same devices were put up among others in Los Angeles, New York City, Philadelphia, San Francisco, and Portland with zero incidents. So yes, it is surprising that the Boston police decided to treat them like IEDs.

QKD is only safe against MITM if you have pre-shared keys between the parties. At that point you might as well use symmetric cryptography which is immune against hypothetical quantum computers and infinitely more efficient than QKD.
