When can you call yourself a scientest?

After bachelor's?
When you're published?
When other people refer to you as one?

Ok /sci/ this is less of a pure scientific issue, but a global, social one.
Undeniably it would benefit all scientific fields both researching and industrial, if humans began cooperating as one species and came to a planetary understanding of our.. well, planetary existence.

it would be in the interest of science to remove the social stigma of the hardsciences being for virgin-nerdy-males, to see to better science education in schools, to.. for example make the internet globally available, to enable more people to study sciences. Education

i wouldn't know of such an effort by the science community, other than the occasional prominent scientist giving his opinion in interviews and such (please tell me, if there are).

essentially, world peace and global cooperation is in the interest of science and should therefore be worked towards, or isn't it?

the lie of egalitarianism makes you believe that anybody can do this science stuff.

since antiquity its always been a social minority that were the gatekeepers to civilization. thats not going to change just because you force feed textbooks to kids.

A man of science meets a priest. The former demands the latter to abandon his dogmatic beliefs and join the pursuit of knowledge. Humans must unite he says. The priest refuses and laments the shallow wisdom of the scientist. Oil and water cannot become one.

This is the only thing left of human civilization, miraculously preserved in ice for millions of years. By some strange coincidence an advanced alien species finds it and studies it in detail.

You mean a connection between the Earth to the Moon?

Disregarding the scale in question, how do you propose to have the Earth-side of the connection move across the planet to keep in place with the Moon?

I don't know where else to ask this, but google is really not being very helpful. Is there ANY place where I can get Shigley's Mechanical Engineering Design *IN SI UNITS* *HARDCOVER*, preferably 10th edition. I can easily find softcover print in SI, and hardcover in burger units, but don't they make both?

Theories of Intelligence Thread?

You're all smart folks here so what the hell is intelligence anyway? Is it a fixed, immutable quality? Are there multiple intelligences? Is it possible to substitute knowledge for smarts? What gives?
35 posts and 7 images submitted.

Intelligence is defined to be the ability to have cognitive abilities, or think. The word has been defined by us, so it's safe to assume that we're what we refer to. There's a difference between instinct and intelligence, a bird flys south for the winter because it knows it has to, and a computer follows code because it's designed to. If a bird or computer want to be intelligent, they need the ability to think for themselves, in these cases, an example would be a computer being to write their own code, and follow it.

>You're all smart folks here
Not all of /sci/ studies either math or physics.

>what the hell is intelligence anyway?
Ability to derive new information from old information.

>Is it a fixed, immutable quality?
Pretty much. You can temporarily boost it by using creatine (blood starts to better rush into your brain) or getting mild electric shocks to your brain, but the results are not that impressive.

>Are there multiple intelligences?
Of course there are. For example people who have had brain injury may sometimes lose some of their abilities while others stay. This indicates that all intelligence is not a single entity.

>Is it possible to substitute knowledge for smarts?
If you have a lot of information in your hands, you don't need to derive so much new information. So yes.
>>
>>8316913
>What the hell is intelligence?
What's intelligence for you?

For me it's the high abstration ability the human being has. You can say it's immutable, but there are different types of POV lessons that each kid have more/less difficult to understand. This cirumstance makes defining intelligence more difficult.

I think there is a innate part of inteligence, which makes it easy to associate ideas, even though your learning skill depends of your mood, physical state, goals, anti-anxiety routines, association methods, etc...
A great example are kids geniuses who got their degree at the age of 15/16.

Most people can actually do a double Math/Physics degree. It's not that difficult, but there are some requisites people don't have:
-Strong math basis
-Physics overview
-Routine stablished

I personally found time for bussiness/public relations and my "hobbies", when I was studying for my degree.

I agree it's very difficult, specially if you got autodestructive habits. But I read started to read a lot of self-improvement books and efficiency-efficacy texts which made me understand better my past depression-anxiety cycle.

>Are there multiple intelligences?
No. I think there are multiple interests that people pursuit. If you have passion for something, often you will get good with that passion of yours. But most people let their habits sabotage their dreams.

> Is it possible to substitute knowledge for smarts?
I don't understand this question.

I stopped caring about biochemistry when I was introduced to the concept of enzymes. What a crock of shit. If your reaction can only be completed by inventing random coils that don't exist, like some kind of life deity , then you are fucking wrong and the chemistry is flawed. Same for protein folding solutions that basically say "the correct answer is whatever the correct answer is". Thats what the thermochemistry said transcribed to words but god forbid if i wrote in down in english instead of the ancient greek runes the teacher word mark me wrong.

Biochemistry is logical and calorimetry never lies my ass. It is just as flawed as any other human construct.
