Hey /sci/,

There are two modes of being: Coexisting and Dominating. Define Coexisting as existing in such a way that the damage done to other beings is minimized. Define Dominating as maximizing the spread of patterns that are similar to one's own patterns.

The majority of history has largely been a history of Dominating. This includes biologic and anthropologic history, as well as modern economics and zeitgeist. A Dominating society requires Balance of Power to sustain Individual Rights (=IR), a Coexisting society does not. Note that a Dominating society with IR will be violents towards beings outside of society (like animals in our case), while a Coexisting society will not.

Now, at one point in the future the Technological Singularity will come. AI built in a Dominating society will be Dominating itself. However, because the power of AI is both variabled and not limited by architecture, there will be no Balance of Power in a society with AI. This means that eventually the entire society will become part of only one entity - the strongest AI. The Technological Singularity will predate near Lightspeed-Travel.

Putting this all together: If we are visited by Aliens (biological or artificial) whose society contains more than one individual, then they will not intend to harm us, because they are Coexisting. If they weren't Coexisting, they couldn't have more than one individual because of the above reasoning.

You didn't understand it. Read the definition. It's not about the "hierarchical status" but about world-view.

How hard is it to design a wing?

I know little about aerodynamics, but I imagine it would mostly just be plugging numbers into equations.

>>
>>7797700
design a wing for what?
If you already have a wing model and just need to know its characteristics, sure you could plug and chug.
If you want to design a new form or whatever, you need to model the whole thing, simulate, make prototypes, run trials, analyze data, improve initial design and so on until you reach a satisfactory design.

But that's not a job for an "engineer" with a mere BSc
>>
>>7797718

Design one from scratch, but to keep things relatively simple it would just be a glider i think - im smart enough to be worrying about fuel lines and control systems.

Do you know what I could use to model potential design? Would Solidworks be practical?
>>
anyone can build a bridge, it takes an engineer to just barely build a bridge.

A wing that just works wouldn't be too hard. But does this wing work well? Is it held up to any safety standards to commercial use? There are alot of questions.

Book ten.

Propositions 85-90.

A couple things, first of all, why is the porism on proposition six constantly referenced? In the case of the former pair, it is always BC and CD, square numbers, and the latter is just another whole and annex squared. This would make more sense if there were a triplet of proportional lines for the former case because then the square lines could be as the first to the last.

But barring that, my second concern is in the vein of how they are used. Like why isn't
the whole squared : annex squared :: whole number : larger square number

Instead it's 'smaller square number : whole number', which doesn't make any logical sense.

I wonder if trees would be able to grow taller in such an environment because less gravity the closer you are to axis so the easier it becomes to transport nutrients further from the roots.

Will we ever be able to see the multitude of colors and stuff that the 3 cones in our eyes don't allow us to?
Is it really completely impossible without implanting more cones or something? Would even doing that work?

Please respond, it bothers me that there's stuff I'm not seeing.

Maybe if we could design retinal pigments that react to different frequencies than our own do, and then implant them into stem cells and let them grow in there.
>>
>>7796020
>>7796020
this means that you would have to design enzymes that anabolize those new pigments and then introduce genes for those new enzymes into that stem cell, too. we are talking about up to hundred genes plus all their regulators sequences introduced in a way that does not switch off any important original shit
seems more or less impossible to me because designing those new synthethizer genes alone could take hundred years or so.
>>
*forgot:
and it would be much easier to simply modify the already existing pigments with highly selective drugs, bound to aptamers or something

Why do people go into these courses if they have no interest beyond getting a degree? It's like no one has read about the topics they're studying.

people have other things to do, surprisingly.

It's because you're studying a meme degree instead of a professional degree. That's the kind of quality classmates you can expect untill you get to grad-school.

You need to find post-docs and 'senior' grad students in the group and talk to them.

Find someone who knows more than you do and who is willing to talk to you about the most recent literature on a daily basis.

Find someone who has published with your boss and ask them how they brought the project to completion.

Hey do you guys know what the best radioactive material is to keep you warm while being as safe as possible?
Preferably from like 0 to 5 meters distance from the source of the heat decay. I'm in my 2nd year of applied physics at Uni and may get some access to certain useful elements
