What did you expect? I think administration once told me degrees for people who graduate with less than 3.5 are meant to be consolatory toilet paper for all their troubles these past 4 years.

Im new and I was just wondering why /sci/ seems to really appreciate philosophy
Isn't it just empty thought / contemplation. I get thinking is important (ofcourcse) but you can just think logically and get a greater understanding than just guessing?

They don't recognize the symbols because they didn't pay attention in classes, somehow graze their ears through the finals, and can't be assed to learn them once they are out of school
>>
>>8914785
People don't get it. Don't want to learn and I have no idea how one could live with such an unstimulated brain. Unfortunately ignorance really is bliss for them so they take there emotions and place it infront of anything meaning full and live their lives blind and enjoy their happiness. It's like religion they just do what they are told to enjoy themselves probably havent even thought that this happiness they rely on is just conveniently moving atoms
>>
>>8914785
Seeing lots of unfamiliar symbols all at once just makes expressions incomprehensible. I remember being put off by algebra when I saw it until I actuslly started learning it, and just skipping over anything that had integrals in it when reading until I actually learned calculus.
Your brain basically just says
>ooooook, lots of shit I am not familiar here
>this will take some time to parse and understand, and I do not wish to spend that much time on this

These guys are rule-breakers and unorthodox in their approach to excellence, with undeniable results. I've once seen one say, "We're experts in becoming experts." Can /sci/ recommend any meta books that might sum up that quote, what might be useful in self study and learning of /sci/ related subjects?

I don't know how that's hard sci-fi though.
>>
>>8914530
Childhood's end by clarke was excellent and that's really where he shines, but I hesitate to call it "hard" scifi. 2001: a Space odyssey was mostly just sagan's "pale blue dot" repackaged as a novel, and they get progressively worse with each installment. Rendezvous with rama was interesting but I never read past the first one.
Asimov I remember hearing somewhere was actually an engineer so may have a few more insights worthy of being called "hard" scifi but I only read the first "foundation" novel and all I remember was that since every chapter 50 years passed, you could never get attached to any characters and it lost my attention. Sorry I can't be more help.

Consider that there is:
>luck in being born with a high IQ
>luck in being born with good genes to attract the opposite sex without trying
>luck in not being bullied and developing poor social interaction skills
>luck in choosing friends you can trust
>luck in learning new things with little difficulty
>luck in having good mental health and not killing yourself after persistent failures
Are there any points of our lives which we actually have any control of? Is free will just one big fat illusion?
Is "hard work = success" only possible if you have the luck to have good mental health and are in a supporting environment during your struggle?

This is a topic which has come up, fairly consistently, throughout human history.
The general consensus, is that conditions outside of your control weave the major threads of your life, but random chance and your actions decide the details.
In my experience, it is very difficult to consciously change the course of your life, but with insanely hard work and willpower, one can get control of about 50% of their path.
I am looking for a project to do over the summer to get acquainted with some tools used in the field of machine learning. Ive heard a lot of things about Tensorflow, would this be a good starting point? Google is not giving me much to work with, what are interesting things to do with it?

Bump. Projects using libraries other than TensorFlow are welcome as well, interested in anything machine learning actually.

So i was reading that large objects move slower to the perspective of smaller objects so if we had a super huge object like unrealistically big could we possible be able to travel faster than light? (please embrace my stupidity im just curious)

huh ?
>>
>>8914046
The volume of an object is irrelevant. Things do not appear faster or slower due to volume.
>>
>>8914046
what you're referring to is the time-dilation, due to gravity, acting on the larger mass, as observed by a frame of reference far from the same said gravitational field. To the outside observer objects within intense gravitational fields appear to be moving "in slow motion" just as from the perspective within the gravitational field those outside appear to be moving "in fast forward". Ironically both are simultaneously true due to the corresponding spatial dilations occurring concurrently.
long story short, no, your idea won't work because the ultimate transmittal rate of information remains the speed of light under all potential observation states.

>TL;DR - Is our glyph system efficient for computer science?
Let me elaborate. I'm taking an introductory computer science class as part of my engineering course, and a lot the material covers logic gates which leads into 2's Complement representation of negative numbers which leads to bit-registers & ALU'S which leads eventually to ASCII representation of visual characters represented with the hexadecimal.........you get my drift.
The point I'm trying to make is that the reason we seem to use hexadecimals at all is because it is an easier compromise between using only binary to represent all numbers and letters and symbols and while efficient enough to not be impossible to compute.
We only seem to *be* in this situation because we use 26 letters, 10 numbers, and 30-40 odd symbols and characters to represent term grouping, math functions, etc.
But do we actually need this many? Would a more efficient humanly readable, speakable, and teachable language make digital representation an easier process? Would compromising the number of unique symbols and glyphs mean a more complex code to represent the same thing?
Can we create a working human language and computer system with 32 unique glyphs? 10 letters, 12 symbols (a space included), 10 numbers?

I was under the impression that octal/hexadecimal are just used to make numbers more human friendly, not necessarily to relate them to ASCII.

What is that plastic taste when you drink out of a water bottle? Is it dangerous? From what I've read online people disagree whether or not it is dangerous.

it's plastic molecules
whatever you store your liquid in will have some particles from the inner surface diffuse into/bind onto the liquid
it's the reason milk tastes different when you get it in a jug or in a carton or in a bag

Fair enough but is it dangerous? Drinking plastic doesn't exactly sound like the safest thing for your health. All of the water I have tastes like plastic and I don't have any access to another source right now.

Dude in europe and italy most of all we drink from plastic bottles all the time, not from taps. No consequences.

Hello /sci/. I was watching a video where Neil Degrasse Tyson was having a conversation with an individual about the possibility of hostile aliens attacking earth with the intention of acquiring more territory. Tyson was saying that an alien species may not have the biological drive to be territorial and that there are species on our planet that are not biologically driven to be territorial. My question is, what specific species are not territorial? If there are any that are non-territorial? I'm searching but I can't find a conclusion for his claim.

Off the top of my head, the Lemon Shark is distinctly not territorial.
Also, a lot of schooling/herd animal aren't exactly territorial.
