Our 2-year old understands pretty well that he can't disturb me when I'm working. It's not like there's zero distraction, but it's no worse than random people stopping by to chat when I used to work in an office. I

Well, if Starlink isn't profitable, it won't be long until all those sats have deorbited, either.

Except you're not actually demonstrating the density. That could have been one satellite if you exposed long enough. It's like taking a picture of the one car every day driving on some empty road and then coadding them and claim

You don't really need a lot of kinetic energy, it's not like satellites are armored. I'd think a pretty small kinetic energy, like a rifle bullet, would do it (depending on where it hit, obviously.) The trick is delivering th

Well, one reason is that without metrics, prejudice and bias is much more likely to win the day. "I just don't feel like they're doing a good job" is affected by all kinds of things unrelated to actual performance. At le

If you don't need that accuracy, why would you use a DS18B20 in the first place. You can use a dirt cheap NTC.

That's not what it's saying though, it's merely saying that structured enrichment activities are no better at improving your cognitive skills than the other things kids choose to spend their time on if they weren't for

The difference is that we can assume that this online-only move, unlike enrolling in an online-only university, is temporary. It does not seem reasonable to kick students out because one semester is online. It's extremely disruptive to

Absolutely not. Maybe the US should , but according to the rules, a student visa is "nonimmigrant intent" and expressing the desire to stay in the US after your studies are over may in fact be grounds for denial of a visa because

Another thing that we discovered when testing out using Modelica for some stuff is that it is very easy to design yourself a model that can't be solved. The whole premise of the "object orientation" is that you can just compo

You missed the "controlling for no other factors" qualifier.

Weren't those projections for the "business as usual" scenario? Isn't the fact that the number of actual cases are far lower just a reflection of the fact that society has, in fact, responded by changing the situation an

Satellites spend most of their time near their extrema in latitude, though, so that's why the current constellation offers northern US/Canada and not areas south of there.

Sorry, but an anecdote of the government failing to do something is no more an argument it won't work than an anecdote of a company failing to do something is an argument that won't work. Especially in light of the OP's exi

You need the user terminal and it seems unlikely those countries would allow SpaceX to ship the UTs there without an agreement.

I don't quite get everyone arguing about these uncertain death rates. It's beyond dispute that over 100,000 people have died in the US, does that somehow become more acceptable if there are twice as many people that have had it bu

I don't know that it's political , per se, to observe that some people say stuff that most of the time seems unrelated to facts and thus acquire a behavior of discounting said people. Distrust can be earned regardless of politics

I don't think that's true. As far as I know, typical AEB systems are radar-based and can't determine what's on or off the road, so they rely on Doppler to pick out the car in front from the environment. If you're dr

Indeed. If you want to switch to a less efficient propellant, you also have to explain how to make the launch escape system work with it, otherwise you've traded the extra safety of not having to handle hypergols for a massive extra ri

Actually, SpaceX was founded in 2002, so closer to two decades than one.

Believe me, it's absolutely disappointing. Not unexpected , mind you, but people would definitely prefer to not have things blow up.

A few months is enough time for breast cancer to go from stage 1 to stage 2 ... Do women normally have breast exams every few months?

It seems pretty far from "worst imaginable". I mean, it's not like it goes into an uncontrollable dive.

* I think if the scientific community were being honest, they'd say they don't work great, but it's something, and every bit can count. Funny, because that's exactly my impression of what they are saying.

"They are NOT effective in preventing general public from catching #Coronavirus" This statement (my emphasis) is, as far as I know, still correct, because masks are only effective if fitted properly and people are trained to use

Science is science and policy is policy. In the end, if you want science to be useful, you have to recommend a policy, and scientists can do that, too. You just have to be clear on what is scientific results and what is policy recommendatio

John Insprucker just talked about this on the webcast and pointed out that with the chilled propellants used by the F9, it's also not possible to wait after prop load has started because the propellants will warm up and change engine p

It depends on the target orbit. For launches to the ISS, you have to launch at the correct instant because even a few minutes later means the ISS is so far ahead it will take much longer, and use more propellant, to rendezvous. I think they
