Let's not paper over that gap and find the root cause instead

Let's unblock that gate

What? No one says you can't say hello. It just shouldn't be the only thing you say

Hello's an established communication protocol that allows the speaker to verify the target is available, listening and ready to initiate a conversation. I've only ever seen this site quoted to defend people's brutish behaviour. If we're going to discard centuries of consensus, I say why stop there.

If you gotta call someone for support, do you say hello and wait for them to say hello back or do you just unload your question?

> If we're going to discard centuries of consensus

are we? imo there's just a different form of consensus for async communication, a more apt comparison would perhaps be a snail-mail letter: would you send a letter with "Hello!" and wait for a reply? just include the hello with the rest of the message :P

maybe the disconnect people are having with this is whether instant messaging is actually async, or does one draw the line at email?

> Hello's an established communication protocol that allows the speaker to verify the target is available, listening and ready to initiate a conversation

Which isn't relevant at all in asynchronous communication methods like messaging.

Phone calls and messaging are different.

Almost all chat apps provide presence and availability to would-be chatters. They already know if I am available and open to chat.

Phone calls are not the same communication mechanism as instant messaging. Look at the timestamps in the mock screenshots and think about holding the other person on the phone for that long before you say your second line.

Imagine in the 19th century, you receive a telegram consisting of only

  HELLO STOP

(Didn't you have to pay per message?)

That's probably already true for 7 days or less

Large storms regularly result in some customers with lack of utility power for more than 7 days for some customers. When storms take out major transmission lines and roads and bridges, you can end up with some pretty lengthy outages, and fuel deliveries will also be difficult.

Look at data center responses from Hurricanes Katrina and Sandy. This guy [1] was onsite for Katrina. Lost utility power on August 29. They did have some access to fuel on Sep 1, but pretty spotty until maybe the 3rd. Looks like power started coming back in some places Sep 8, and maybe widely restored on Sep 14th.

I would say, by 7 days in you'll probably have a good idea of if 30 days might not be enough.

I need to bring this out:

7 days of unreliable electricity wouldn't be unheard of for a very large storm

If you define the initial conditions such that their relative velocity is zero or parallel to the plane, yes. But that's not the case in general.

I'm pretty sure there is always a unique solution to the equations of motions (safe for some pathological edge cases perhaps). Classical mechanics is deterministic, after all. But for more than two bodies, there is in general no solution in closed form, and it's often chaotic, so not even computeable for arbitrary time frames.

The "about" info states that all of these are computed numerically.

It's well organized, the animations are smooth, and it looks beautiful... I'm not sure what to do with the information, but it's mesmerizing and fascinating. Great find!

Get inspired and spend a rest of your life looking for new 3bp solutions.

Handy if you get really good at it because "the rest of your life" will be indicated by the unavoidable countdown timer that shows up in your vision!

Something cool and interesting for its own sake. A rare find.

Pretty useful if you’re a Puppeteer, though.

Or trying the solve a Three Body Problem.

Klemperer rosette FTW.

I also don't remember checks, but I believe that having an email address of an approved organization was enough to pass.

No. You do have checks, it's just that once you publish 4-5 papers, 99% of your field is open to you so you never have to do the checks again.

I checked, you're right, but I think it's important to note that the prize did go to Perelman and he declined to accept.
