Finally a Doctor on the News Talking Fucking Sense

newtboy says...

Yes, but my understanding is that the point isn't to starve the virus for hosts until it's dead, it's to slow the spread enough that hospitals aren't overrun. When they are, death rates explode, logically from 3-3.5% up to 15-20%. Of course, this plan relies on the hope that immunity is relatively full and permanent, something we don't know yet.

If people weren't morons, I would agree about parks and beaches....but they are. Even those smart enough to try and social distance in public often forget and hug goodbye, and most aren't being that smart.

The problem with sending people back is we don't have a single study on immunity. We don't know if you have full immunity after recovering from being infected, or if so how long it might last. Many other coronaviruses mutate enough that immunity is for one season at best. We need to study the virus in detail before making assumptions on life and death issues, and it's smart to err on one side of caution with stakes this high until we know. Opening up before we know is a pure gamble....the odds might be good, but the stakes are sky high.

In a near worst case scenario, it's possible that Covid19 is going to remain as dangerous as it is today for some time with reinfection possible, and that any future vaccines will need yearly changes and booster shots to be effective, like the flu shot but hopefully more effective. In that case, the best we can really do is be prepared for a constant flow of large numbers of patients and deaths. That's going to require a complete retooling and expansion of the medical system, but silver lining, it's hundreds of thousands of good paying jobs that robots can't do...yet.

If everyone somehow isolates and we get down to only only 10 new cases a day, and we let everyone out, that only resets the clock to February with the addition of a million or so people already infected and immune. Everything goes back to shit in another couple months. People's behavior changing will help slow the spread, but will not prevent it. There's plenty you can do outside the home a safe distance from other people with minimal risk, certainly less than just going to shop for food. It's ridiculous they are shutting down beaches where it's simple to walk 20' away from anybody else. To limit crowds just close down parking spaces.

Antibody tests should allow recovered people back into regular life, but the only way we get a lot of recovered people is to have a lot of sick people first. Keep the elderly and high risk people confined, and let everyone else out with reasonable precautions(no gatherings over 20, etc). The only other alternative is a 6-12 month lockdown and 100% testing, which is simply never going to happen. You would still have to lock down the borders until the rest of the world has it under control too.

SpaceX's Falcon Heavy Lands All Three Boosters

How a 1929 Silent Film Created the Countdown to Launch

BSR says...

Before the space shuttle would launch, the main engine would ignite first. After six seconds the two solid rocket boosters would ignite and the shuttle would launch.

The six second delay was necessary because the main engine ignition would rock the "stack" or the entire assembly of the shuttle, fuel tank and boosters forward. It took 6 seconds for the stack to return to the upright position.

This 6 second period of sway was referred to as "twang."

Figured I'd pass that little bit of info on to you in case you're ever asked about twang on a radio quiz show.

Today i learned the water used during a launch is used to dampen sound waves.

Launch Of Elon Musk's $250,000 Tesla Into Space 2/6/18 LIVE

Jinx says...

Watched it live. Hype was infectious. Seeing the two side boosters coming down together in almost perfect synchronisation was quite a thing.

Best of the best Shuttle launches

BSR says...

I lived in Cape Canaveral during the shuttle program and was fortunate enough to watch all but 5 launches live.

An excellent video with scenes I thoroughly enjoyed in slow motion and HD.

A brief mention in the video about the 6 seconds from when the main liquid engines ignite until the solid boosters ignite is called "twang."

When the main engines ignite, the power causes the whole assembly to rock forward. It takes 6 seconds for the assembly to fall back to vertical again and then the boosters light up and away it goes.

Boston Dynamics New Nightmare Inducing Robot-Handle

Jinx says...

ahhhh yeah

geekgasm at the end there.

But ok, now the wheels need to be able to lock tight so it can walk on them and then attach rocket boosters to help it pick up speed and/or hover/fly and you've got mechas. All we need now is to develop hairspray strong enough to maintain those anime dos and we are golden.

NASA’s new High Dynamic Range Camera Records Rocket Test

newtboy says...

I had not realized that the solid rocket boosters were steerable....at least I hope they are moving the nozzle intentionally and that it's not moving around on it's own.
Incredible camera...at 1/4 speed you can see the pressure waves move through the flame trail.

Late Night with Seth Meyers: Kansas Tax Cuts

MilkmanDan says...

@eric3579 Thanks for the quality!

My mom is president of a district school board in Kansas, so the "education" parts of the cuts have hit really close to home for her (and by extension me, even though I'm not living there). Very very tight budgets. Most music programs got drastic cuts years ago, and are effectively gone now. AP programs for college credit? Gone. Good teachers for academic subjects? Usually bail for greener pastures very quickly.

...But, being rural Kansas, plenty of money gets spent on bus / coach / equipment / facilities for the football team. To be fair, a good chunk of that comes from booster clubs rather than gov't. Still shows where the priorities are.
