The musk biography made me believe that I should have gotten a physics degree. Or at least taken physics. Can anyone recommend any online physics?

Seconded, definitely need to watch or listen to a few minutes of that link.
I loved the bit where Fisheries and Wildlife refused to provide the shark density information because they didn't trust their own department with it! Apparently SpaceX must wait patiently to take humanity to the stars because sharkfin poachers have infiltrated spies into a wildly unrelated government agency. I feel like SpaceX should just launch the damned rocket and then if anyone from the government takes issue jus…
If it turned out the federal government was just dicking around out of some unrelated grudge towards Elon Musk, half the country would still support them. Some days most of HN would too.

#23Did Fisheries and Wildlife finally figure out the areal density of whales in the ocean for impact probability estimation? https://youtu.be/JN3KPFbWCy8?t=4742
I recommend the above link because it gets even weirder than you might surmise from the parent's comment.
The seal story is amusing as well. Isn't there some other way to figure that out besides a real test? Does no one know the hearing ability of seals before?

I mean that’s kinda working with regulators sometimes… you just get lists of random questions every once in a while for several months. It’s fun when the employee turns over and you get to go through the same thing again with random questions that go off a slightly different tangent.
What else could they possibly do? Some dude at the Fish & Wildlife Service isn’t gonna bust out COMSOL. I don’t really know what people expect.

It would be about the same chance of hitting a shark or whale when driving a boat for about 10 meters.
Footage of a boat hitting a shark - https://youtu.be/yYuh_TNLThg?t=332 this unusual event being .1% of their trip for the day.

The gov is not a monolithic entity. If an organization has power over an important private entity, it comes down to a couple of people and their ego's and I am damn sure their ego loved the idea of making the all important SpaceX and Musk do a little dance for them.

#29It is interesting that T-0 says "Excitement guaranteed" instead of "launch" or something. Besides being funny, it seems like they are officially accepting the reality that it may not go as planned (even at so early a stage), but will be thrilling nevertheless!
Re: Starship’s second flight test
#30If Starship meets its reusability goals it's going to be absolutely nuts. Flying to orbit and back multiple times in a day like an airliner or something, carrying more than the entire habitable volume of ISS every time. It's impossible to overstate how much that would change access to space, and how much of an advantage it would give SpaceX over its competitors (even other nations).
But more important first is to put headphones on seals and play sonic boom sounds to test and make sure they aren't startled by the scary rocket sounds.
(Ok, stretching a little. That is what a seemingly similar survey did at Cape as a part of some similarly goofy bureaucracy thing that has been holding Starship back the last month or so. For Starship they're worried for the risk of what happens if Starship literally falls on a shark) Source: about 1:18:02 https://twitter.com/lexfridman/status/1722686021781835928
