All articles predate the outbreak in Wuhan. Does the simple fact that Wuhan had a new and perhaps inexperienced team looking into bat coronavirus equate to a lab-leak? No... but it is highly coincidental. Especially when considering the source of the bats studied is quite a ways away from Wuhan. Regardless - all terrestrially sourced. Not alien

Okay - I'm the furthest from 'a math guy' you are likely to find here - but I'm guessing you are contemplating a 'fly straight up, turn 90 degrees' thing? Newton probably handles this - and if you have one great big ship with a honking Viking Beard of a shield at the back... Just how much force you need to move it should be simple to work out... But I don't think we even need to. Problem is that the debris is tiny. So let's analogize - how many BBs do need to shoot at a garbage truck rolling uncontrolled down hill towards your house to push it out of your yard? Answer is 'lots'. You need lots of BBs. You also have a time problem. Because you are in a race against gravity. So you need lots of BBs hitting the truck in a short period of time. (You also have a 'space' problem (because space is big) - so you need lots of BBs all hitting the truck in a short time and they all need to be concentrated in time and space to save your house. You can start to guess at the weight needed, because if you have a whole bunch of BBs hitting all at the same time, rather than calculate each individual F=MA for thousands of BBs you can pretty much just smoosh all the BBs together and figure out what F=MA you get for one giant BB... But we don't like math, so we can keep analogizing. So how big is that smooshed BB? Okay - shifting analogies a bit - you ever try to move a bowling ball with a cue ball? Cue to 7 gets the 7 moving right quick, but Cue to bowling? Man, if you chuck it hard it can shift the bowling ball and if you have a bucket of cue balls and a good arm you can get it moving. So clearly we don't need a garbage truck sized BB. Now I'm guessing that a bucket of cue balls weighs more than a bowling ball an... ... ... Huh. Now I realize why people do math.

This is why you need a really good Stellar Navigator team. Or person. Like Spock. (As others have said - the multi-probe thing could do it... another way would be to take a bunch of measurements - fly 1LY, take a bunch of measurements... compare the two, handwave the math and fly to a rendezvous point.

After all individual mirror segment deployments are completed, the detailed optical mirror alignment process begins which is about a 3 month process. In parallel, as temperatures cool enough, instrument teams will turn on their instruments and begin each instrument's commissioning process. Mirrors Webb/NASA

What could possibly go wrong? (Darwin Award?)

"...higher narcissism and lower intelligence." What a fabulous combo.

I've gotten several by just shopping Best Buy mid week. Around 11-1, online site. Mind you, that's just 3070s... but again that was all I was shopping for. Edit - that was all last year, btw (Fall 2020 and Early Spring 2021). I don't know what the supply situation is currently, but it should be better than a year ago - one would hope.

Thanks - that was great! Interestingly, he says that what actually happens is the exact opposite of what I feared: there are two small areas at the poles that are constantly viewable. Wow.

Yeah - I'm getting that - but wondered if there was a region above or below the 'pole' of the orbit that it could not resolve b/c of the shade

Question - with the requirement of keeping the sun shield between the observatory and the sun, are there parts of the sky in the axis of the orbit that cannot be imaged?

Grin - agreed. Besides, predators taste bad. Leaf eaters taste good. Absolutely - keeping the children entertained and exercised is a great thing for the scavenger to do. None of which was my point, however. When we set out to domesticate the cow and sheep and goat and horse and etc. we likely had to kill most males and obnoxiously dangerous females and then teach the babies to not freak out and get all the other hoofed meat angry-scared and kicking down the enclosure. So using the dog (which likely domesticated itself) to calm down the baby food and show that it's OK to be calm around people probably sped up the process.

Sorry - coronavirus was one of the things studied in Wuhan, including those that had been previously found in humans and those that had not. There was an article that came out a year or two before the pandemic about the development of the facility and concerns of it being rushed to certification before the building and staff were ready.

The simplest explanation is usually correct. Wuhan had a research facility doing research on human coronavirus before the covid outbreak. The outbreak started in Wuhan and spread to the world. .

It only takes one... Some of what I enjoy reading is 'rise of civilization' and 'early human' research. You will often find reference to our domestication of various animals at guessed at times, but rarely do you get explication of how that happens. How early humans who were dangerous hunters managed to capture and keep calm their 'save for later' food. From this (unrelated) article - I'd hazard the safe guess that we were helped by dogs. https://www.huffpost.com/entry/dog-raised-cheetah-cubs-coby-dies_n_61d9c356e4b0bcd2195fd7d5 (Article mourns the death of a famous zoo dog that helped infant animals to be less instinctively nervous around people.)

Not sure I understand your question. Are you asking if someone takes a licensed design and improves on it, if that makes it unique? Or are you asking whether when stolen tech gets upgraded does it count as a domestic product? Not sure it matters, does it? Is the J-20 a uniquely Chinese design? No. But it is still a Chinese aircraft.

And yet, somehow we muddle along. @SunlitZelkova - I get and respect your concern. I just don't share your sense of the inevitable that the worst is going to happen. Bad things can and do happen... but that does not mean they always must.

My dear friends from the 1800s agree!

is exactly what I'm hoping for. We need a new

Chevy, Ford, Porsche, Oshkosh and General Dynamics Defense. You get companies putting out cars, utility vehicles, sports cars, transports and military vehicles. You don't have massive government oversight, because they are as common as cars. Maybe (and I say MAYBE) NHTSA (NSTSA?)

The first science images are expected in about six months. "We start with the mirrors off by millimeters, and we're driving them to be aligned within less than the size of a coronavirus, like to tens of nanometers," said Jane Rigby, Webb operations project scientist. "It's this very deliberate process that is time consuming." Rather than showing off initially blurry "first light" images in the next few weeks, "we want to make sure that the first images that the world sees ... do justice to this $10 billion telescope," she said. "So we are planning a series of 'wow' images to be released at the end of commissioning." Webb telescope deployments complete as side mirrors rotate into place - CBS News

There could be 18 ways to mess that up.

Let's put this to rest: its not extraterrestrial. It originally infected humans in Wuhan China. Somehow jumped from animals to people (regardless of whether it leaked from a lab or not). Spread from there to everywhere. Anything else is subterfuge and obfuscation.

Actually... no. You can see the projectile. Mostly as a black flicker - but you can trace the arc of fire. Strongly depends on the angle of view and lighting. Artillery is much easier (beeeger bullet). ... Now for something weird: one time after spending a week on a rifle range, the atmospherics were just right for me to see the flight of 5.56 bullets and call the strike locations before the targets had been pulled and marked. I really freaked out a few Marines by demonstrating that I knew, before the target marking crew did, where the bullet had hit the target. What I was actually seeing is reminiscent of a contrail; the disturbance in the air, caused by the passage of the bullet made it clear to me where each round hit. I only encountered similar humidity, light and temperature twice more - and that's in 20 years of professional shooting. It only worked if I was standing over the Marine while he shot. It's pretty cool. @ARS Not sure if my story answers your question: but wiki shows these flying 8-900m/s. 5.56×45mm NATO - Wikipedia Edit again: Having been on both (many?) sides of bullets flying I can tell you that you can almost never see crossing rounds. You can see the after-image of tracers but the bullets themselves, no. Incoming and outgoing are a different matter. This is pretty clearly Marines in school (despite the narrator talking about 11 charlie (or whatever) which is an Army MOS designation). Notice how young and clean and uniform they all are. If you look at about 4:00 in the video you posted, they're using only a single increment. Later on he splices in some Army crews and other Marine crews firing... but never, as far as I can see from a short view, does the camera angle get where it needs to be for you to see the round fly. The camera angle is not set up for you to see what I describe in watching mortar and artillery fire. You need to be in line with the gun and the angle of flight, for the most part. With the bigger stuff, like arty, you have a bit more wiggle room, but with 60s just stand behind the tube on a sunny day, or when the lighting is just right and you can watch it arc up and away. You generally only get to see a short bit of the flight; the upward arc. With the rifle rounds I described above - we were shooting at about 1/2 klick. With mortars its often farther.

There are 3 increments visible - but it's been over 20 years since I worked with mortars so I can't get more detailed
