> ...gasoline gallon has 33kW worth of energy in it... kW are a unit of power (energy/time, 1 W = 1 Joule/s), which is not relevant to measure energy content (for a gallon of gas). You'd want plain Joules for that.

The blade of a standard 10" table saw rotates at very close to 100mph (150 fps). Of course, the teeth of the blade point such that they will maximally engage the wood if it gets loose. So anything of small-to-moderate size will accel

OTOH, reading between the lines, it seems like there was contention between the story author and the rebuttal author all through fact-checking. This hints that there is another side to this story.

Much of the discussion of nuclear power on HN centers on the engineering view: nuclear doesn't have climate consequences and uses a very energy-dense fuel. No doubt true. The "administrative" picture is not so rosy! Of cour

I think the article is not in disagreement with you - probably the headline was drafted to generate clicks, but the substance of the article is different in tone. Mostly the article points out that the transportation system is complex, and

I also am strongly allergic to the "family" analogy with the workplace. It should not be analogized to that - even though management sometimes likes to do it. You can leave a company, or the company can lay you off, or re-org and

Second shout out to that particular item, which I bought July 17, 2017, and have used about once a day in the 18 months since, on a gas stove. One of the best nonstick skillets I have owned. Even heat distribution, and no issues with peel

I appreciate the reply. I happen to know some of the GRACE team, so I'm personally predisposed to respect their results. But, it's also significant evidence that the retrieval was re-implemented by 2 other teams, one US, one Ger

You know less than you think you do. GPS is not part of the measurement suite in OP, but better than 1.8 cm vertical resolution from GPS has been possible since the late 1990s, using after the fact orbit determination. It is now routine to

Well, six times faster mass loss now than in the recent past. I linked this press release because it has a link to the PNAS article, which is free and describes the findings in greater detail.

I also skimmed the video. I felt it to be superficial in dismissing solar, which others nearby have pointed out has costs /kWh that are comparable to fossil fuel. The arguments presented for dismissing solar were non-quantitative and

Yes, almost all folks at Moffett (NASA Ames Research Center) are US government employees, just as at NASA Goddard. They will be on furlough unless their job is essential. STScI/APL in Baltimore, like JPL in Pasadena, are technically c

That’s for selected people, and $6k max. It won’t solve the problem, and it’s a bandaid that shouldn’t be necessary anyway. You don’t tell your employees to just hang on indefinitely and ask around for loans.

This could indeed be. I thought your remark that there had been so many national emergencies was interesting. This turns out to be true — color me surprised. Almost all of them seem to not involve spending money — they are prohibitions on

Thanks for that alternate way of thinking about it. As an engineer, half of my intuition about the FFT comes from the notion of the "frequency domain", and the other half from "change of basis". The explanation you gave

I'm surprised to hear this claim: about equations being easy in Word. I've written long documents in both, and (1) the math layout in Word is crude/inelegant; (2) there seems to be no easy way to change notation in Word. If

Here we seem to disagree. I think it's clear that this "devaluation of the press" is being pushed far beyond reason by people who have their own reasons to cloud the notion of an objective truth. My caveat was more circums

The author, James Risen, has had a long trajectory as a reporter. The OP (which I admit I have not read all of yet) touches on Risen's reporting on the Wen Ho Lee case while at the NYT. Risen and Gerth's story, and their later f

I do like the notion of using a relay. In 1999, JPL lost Mars Polar Lander, and didn't have telemetry to know why . One of the major lessons learned from this loss was to always have telemetry of Entry, Descent, and Landing (EDL)
