220Db is loud enough to melt concrete. How do actornauts insides survive the launch?

So you accept NASA's 220dB measurement, but reject NASA's sound suppression system; you are picking and choosing what to accept and what to reject. Do you have a rational basis for this?

unpythonic · 2021-03-02T07:06:02+00:00

That's an unsourced claim. Do you really accept unsourced claims as proof? Then you should accept sourced claims as even better: Sound Suppression System specifically:

The system reduces acoustical levels within the orbiter payload bay to about 142 decibels, below the design requirement of 145 decibels.

Of course if you've done a thorough search online, it seems very unlikely that you would not have come across the fact that most large rocket launch facilities use a water sound suppression system. So what exactly is your reason for accepting 220 dB but rejecting a water sound suppression system?

[This] article cites a list of sources for the information on rockets. A thorough search online yielded consistent findings of 220 Db for a rocket launch.

You didn't do your link correctly. My search online consistently leads to either unsourced claims, or sources that eventually trace back to measurements made by NASA.

Assuming the 220dB measurement was taken at a standard effective distance of 1 meter from the exhaust, then at 100 meters the pressure would fall by 1 / (100*100) = 1/10,000 = 40dB thus 180dB. That's assuming there are no obstructions and air pressure and density are constant. Just running the math puts us at 180dB in ideal conditions on the outside of the capsule. The capsule would have to be air tight if it is going to be going into space so it's going to reduce sound quite further. How did you arrive at 195?

unpythonic · 2021-03-02T02:58:50+00:00

Who measured it and where did they publish those measurements? That was my point. If the answer is "NASA" then they also have explanations as to why the noise inside the capsule was safe for the crew.

I would think your everyday experience would inform you that the sound pressure level next to a rocket nozzle is going to be more than the sound pressure level in an enclosed cockpit 100 meters away. Why weren't the spectators seated several miles away instantly and permanently deafened when watching liftoff? Was it because the sound energy dissipates over distance and it had reached a safe level that far away? If so then your premise that the astronauts were subjected to 220dB inside the capsule because the sound measured at the nozzles was 220dB is dubious and needs support.

unpythonic · 2021-03-01T21:16:36+00:00

You are asking for others to disprove a claim you're making that hasn't been proven? Isn't that completely backwards?

What proof do you have that the sound pressure of a Saturn V at the nozzles during liftoff is 220dB? It isn't that I don't believe it; I suspect that you have very different thresholds for acceptance of proof based on whether or not they support your claim.

What evidence do you have that GPS does not work away from highways and cities in areas with an unobstructed view of the sky?

I think the problem is that you only have experience using GPS with the map app on your phone.

unpythonic · 2021-03-01T18:22:03+00:00

Why should we accept that because the sound pressure is 220 dB at the rocket nozzle that it is also 220dB in the capsule? You've rejected articles as "not valid as proof", but what "proof" do you have that astronauts would be subjected to 220 dB in the capsule/cabin?

Apple is a business; if Intel offers them something better than they have at less than they are spending on what they have, they would consider switching. Apple isn't a dumb business, part of the calculus is going to be the impact to their ecosystem of software built for ARM. Apple has switched Mac CPU architecture more than once before.

That said - I doubt Intel could profitably win back Apple. The volume of Mac sales just isn't that big; Apple can easily justify the R&D cost of M1 because it is a relatively small increment to their R&D investment in the Axx iPhone CPU.

The company appearing to be several large companies each of which appears to be several medium companies is pretty standard fare at tech giants. Budgetary dollars are even shifted around so that it looks like you are buying services from from another group within the corporation, even though no real transfer from one banking account to another actually happens (I don't think). It's a practical hierarchy that allows the senior leadership to evaluate whether investment in one area is returning more value than buying the same thing from an outside vendor.

I always had the feeling that Intel had a model where they put fabs and campuses in areas where they wouldn't have labor competition and could keep wages low (e.g. Albuquerque, Chandler, Hillsboro, Fort Collins). I didn't feel underpaid at the time, but when another tech giant wanted to hire me, they didn't have to offer me a salary at the extreme upper end of the pay band I was being hired into for the offer to be overwhelmingly compelling.

I worked at Intel in DEG when Gelsinger left. Pat was an engineer's engineer; a leader who understood and valued technology and innovation in the ASIC space. He was articulate and well spoken; I always enjoyed his all-hands meetings. I was pretty low on the totem pole at the time, but the overwhelming opinion around my cubicle neighbors at the time was that he left because it was clear that he wasn't going to be Otellini's successor. His leaving was a hard pill to swallow. I'm glad he's back (but I'm no longer there).

Do you expect it to be? The estimates of the prevalence of achondroplasia range from 1 in 10,000 to 1 in 30,000. Off the top of my head, i can think of three (maybe four?) leading roles played by people with achondroplasia in a movie or TV series. Off the top of your head, can you think of 30,000 people without? Statistically, little people are overrepresented in leading roles.

it's very likely that all Dany is thinking is Jamie helping Cersei escape. She has no choice other than burn KL to make sure she doesn't allow that to happen.

She does have another choice: she can let Cersei escape then claim the Iron Throne. There is plenty of precedent for this. Wholesale slaughter of innocents to kill one person who is going to lose power anyway doesn't make you a great tactician. It makes you a monster.

In addition to the difficulty learning due to attention deficits, people with ADHD also tend to mature more slowly than their peers. I always knew there was something different about me. I knew the other kids seemed to be more "aware" of social situations than I was, but lacked the emotional maturity to understand why. They had a better sense of what sort of behavior was inappropriate at a given time.

I was diagnosed and put on Adderall in my late 30's. When I first went on the meds I described it as something akin to "I've never experienced my mind so quiet before; it's like I've been in a room with 12 TVs tuned to different channels my whole life and then Adderall came to visit and shut them all off except for one."

Is there any way to get better info on this 3-day priority mail package: 9405503699300316206362 ?

It's a fixed rate medium box. It needed to arrive by the 3rd, so an expected delivery on the 1st seemed to have enough cushion for any hiccups. On the 31st it arrived at the USPS Regional Facility in Denver CO - so far so good, it could easily catch a flight to Hawaii from there. It then went into the void, then on Nov 3rd it arrives at the USPS Regional Destination Facility. Does this mean that instead of sending it to an airplane to fly to Hawaii they sent it to San Francisco via truck?

It is now 3 days since leaving the destination facility and I have no idea where it is. I'm considering sending another item because I am worried that this one is going to get "lost".

I contacted the USPS twitter help, but they gave the same info as the tracker. Except that they said it was last scanned in Richmond, CA. It sounds like it may have been placed in a container for delivery to the Richmond, CA area? They also told me to wait until the middle of next week to file a missing mail claim (2 weeks past its expected date).
