Hi. I have a TI-84 Plus CE and I've spent my four years in high school dicking around on this website and nothing to show for it. I'm now stuck with a bad GPA and mediocre ACT score.
TL;DR: How do I cheat on the ACT?

People aren't so excited about what SpaceX has done (though that's cool too). It's more about their rate of movement – from a single engine test rocket to a reusable 27 engine heavy lift rocket in a decade.

In an industry that has slowed to the speed of frozen molasses, that's a big deal. It's what they might achieve if (an admittedly big if) they can keep up this pace that's truly exciting. It'd be the long-awaited return of Apollo era speeds.

SLS would be cool too if its final form were launching in 2022 or 2024 maybe, but 2030+ (and potentially further with the delays inherent to the industry) is just plain sad, especially given how little of it actually new.

I've read something similar to what you're describing before but perhaps I am misinterpreting you so correct me if I'm wrong.

>Master's in FE/MCF/applied maths is enough to work with existing fundamental strategies in financial engineering.

>PhD is required for working with the strategies themselves rather than the application of them.

If this is the case I'll have to get a PhD. What's the best bachelor's if you're planning on getting a PhD?

It depends on the job, if you want to go into an analytical position that other PhDs apply to, probably not, but since a lot of jobs are code monkeying, I see no problem.

As in being a professor and doing research? You probably have to be good for that, that doesn't seem guaranteed at all, the thing is, it's the same for everyone, just put in the effort if that's what you really want to do, if it doesn't work out you have to get another job just like everyone else, it's not you're gonna be homeless

New Glenn will be first, BFR or SLS second depending on how smoothly everything goes for SpaceX

I personally root for SX but Elon Time is a thing, not to mention their lack of funding compared to Blue Origin.

Also fuck SLS, with the retarded amount of money they've wasted on that thing they could have finished BFR long time ago.

let's say we make contact with an extraterrestrial life form that has very advanced technology and scientific knowledge, etc, etc

furthermore they look maybe like pic related

furthermore, they have no sense of identity, no sense of individual consciousness, don't claim to have any sort of internal monologue, etc.

but nonetheless they're scientifically WAY beyond us and their technology is so advanced that it looks like magic to us

what do the NPC dumbasses think about that? do we somehow say "those supersmart aliens are useless beings, fuck them!!"

or do they instead say "oh wait yeah, the NPC meme is pretty retarded"

>>10016386
no, still a weak argument

magnets and x-rays aren't the end of the story brah. imagine their technology is all based on something really far-out, like their technology is based on their knowledge of the fundamentals of physics which only can only be confirmed by their 50,000 TeV hadron collider. like they have some ridiculously more advanced form of string theory they've been studying for 1000 years longer and they worked out all new equations of topological field theory and knot theory and applied that to design super-intricate nanoscale devices where every single atom is perfectly arranged to 1 part in 10^10?

in principle an alien species could have knowledge that would take hundreds of years to figure out, just like it took about 80 years to figure out quantum theory and make a reasonable Standard Model
>>
>>10016392
Then it takes a couple generation of us wheedling knowledge and prototypes out of them. Since you're assuming they're NPCs, they have predictable stimulus/response patterns that PCs would figure out and exploit.

The extra time/generations it takes just make them really high level.
>>
>>10016401
back to predictability

i disagree. what if they were defensive; they knew asshats like you can exist in this new planet they've discovered, and their collective non-consciousness based decision making apparatus decides to hide their actions, and for visible actions, throw a lot of noise in there and encrypt their true decisions

analogy: the allies in WW2 created completely fake "alternate" staging areas as fake places the invasion of France could have started from

anyhow, on a base level, i detect that your argument is "i believe in NPCs, and their converse, PeopleOfConsciousness (PCs, not personal computers). I believe that PCs are inherently more resourceful and creative and crafty than NPCs, so they win in the end"

and the entire point of the thought experiment is that this line of thinking is retarded, even if you assume that its assumptions are correct

NPC is a dumb meme and you guys need to stop spamming /sci/ with it. you'll have more success on /pol/ where they are looking for excuses to label certain types of people as "sub-human"
>>
>>10016421
Schroedinger's cat would make a shitty pet, that doesn't make it a dumb analogy

Similarly, extending the NPC analogy to hypothetical space aliens and going "nuh uh, they'd be *even* smarter" ad infinitum defeats the entire point as it applies to human interactions.

The fact you don't realize PC stands for "player character", think Operation Bodyguard is some super secret knowledge, and are spewing communist drivel shows you're in way out of your depth.

Please stay out of /sci/ at least until you graduate high school.
>>
>>10016434
>The fact you don't realize PC stands for "player character"
holy fuck, this is a /v/ meme after all

okay, now i know that your NPC meme consists entirely of psychopaths who think reality is a video game and that some people are Non-Player-Characters really sheds some light on how absolutely retarded this whole meme is

if you think that vidya teaches you anything about life, you need to GET THE FUCK OUT OF YOUR ROOM

the fact that you're telling me that this meme exists because of /v/ shit makes me totally confident that it should instantly warrant an insta-permaban on /sci/ from the mods from here on out

There was probably some carbon fiber company with congressmen in their pocket that was going to get an exclusive contract to manufacture those tanks. When the plan for the tanks changed, these congressmen just cancelled the project altogether. "If I can't have this business, nobody will."

This is one of the many problems with government-driven space development.

Dear Sires,

Hello,

In case if you want to use my invention?

As I've decided to submit my invention (pepetual motor machine !) to the interested companies on all over the world ,so here I'm giving a some detailed needs for your understanding .

Put aside all kinds of energy production systems!? and please notify to what is happened on the way of NEW & CLEAN ENERGY product systems ?? Now, It's ready to obtain the all humanity energy needs on this planet earth ,as free ! and, help all the existing live to go on it's good natured conditions ! So I'm requesting volunteers to help to utilize & carry out this matter.

What should be more important than this for you ?! This Meets All the climate change , Propulsion & Energy Needs ; and very more !? This invention depends with all human's safe life On the earth and, all other planets and even in SPACE !? I'm a self-starter by 74 years of old And have been busy my last 23 Years on this matter,During the days and nights , so believe or Not ; That's a serious question ?? Despite of impossible matter, if a person could do and prove a Real & Free and clean Energy generating MOTOR! (self sustain motor) What would Happen !!??....... BUT HOW it's been ENDED ?? : There , (potential power )Changes to Rotation form ;(kinetic energy) ??? in a tricky and special way !!??)) Even 1 to a 100 or more !!?? Yes ! The Theory Is , as this easy !? So, it's ready with all the physical & schematic plans and drawings to offer to all your expert's consideration and -confirmation. then by; if you're interested on this problem:Thank you.

Device was self-made, see photo. Any question? Please ask here.

FEA/CFD simulations are just that - simulations - and rely on a huge number of assumptions. Without understanding and controlling those assumptions, it's very easy to make a model that looks reasonable but doesn't match reality at all. Here's one example, where a flat plate rotated 10 degrees, with no applied loads, shows high stresses: https://www.comsol.com/blogs/what-is-geometric-nonlinearity/

That example may be obvious, but can be harder to pick out when the displacement or deformation is mixed in with (or caused by) other loading.

Don't get me wrong, FEA and CFD are powerful tools that can help you drastically reduce prototyping costs and make better designs, but it's worth investing some time learning about how they work, and even then, I would check your model against some simple prototypes before spending a lot of money.
