Will this thing EVER break down?
I mean, it's been like truckin' for like 13 years.
>The Mars Exploration Rovers carry two 8-amp-hour lithium batteries.
I wish I had a 8000MAh lithium battery that would last this long. Can't seem to go for more than 3 years before mine puff up with gases and become a fire hazard.
Though I suppose you don't really need to worry about a fire in an atmosphere that is nearly vacuum and primarily composed of fire retardant.

I hope not, it's cool as hell.
>>7786764
Eventually and without maintenance, it will break down. I mean I'm pretty shocked it's still going.
What's your favorite branch of math?
>>7784433
Complex Geometry
Algebra
>>7784433
set theory, it's also the most useful desu
How many energy points did you earn this week ?
What are you working on ?
Mission progress ?
pic related is what I'm doing. brainlets only, no high iq shitposters needed. some of us are 25+ iqlets brainwashed by pop math into wanting to underachieve intellectually so don't spoil these threads for us
>dat distributive property
>dat rigorous reasoning to obtain a value for y
makes my peepee firm, /sci/
feels so good to get those correct answers
thanks uncle Sal
dem energy points, feels so good
>mirin avatar, /sci/ ?
/g/ here, can you please tell your man to stick to the cosmos?

Why do even have BSG in your feed? Unfollow whoever retweeted it to you.
No one here respects pop-scientists.

>create unhackable systems
I respect the man but this shows complete ignorance of the subject.
It is literally impossible to create unhackable systems.

He's good for the kids and pseudo-intellectuals.
How much confidence do you have in modern society to overcome the increasingly daunting problems of achieving sustainability with the Earth?
I have every confidence in the future of humanity. The reasons are best explained in this manifesto, which I highly recommend you read.
http://www.ecomodernism.org/
Key reasons;
- increasing development leads to less environmental dependence, and therefore impact, per capita
- the world has reached 'peak child', where global fertility rate is a stable ~2.6 children per woman. Result; better education and opportunities for children resulting in rapid development.
- projected global population at end of century is easily fed by farming current farmland more efficiently (inefficiency in developing world is staggering due to poor access to modern agricultural technology)
Earth is kill my friend. Focus on terraforming Mars.

Well people have been predicting malthusian collapse for a little over 200 years, it's still not happened. So I'm pretty confident.
What made you major in maths? What are you guys going to do in the future?
>>7782611
Because it's challenging and fills me with joy. Research in pure math obviously.
>>7782613
Would your fun and strive for challenging work stall; if you majored in physics or other sciences?
>>7782619
Not him but I started disliking the sciences back in high school. I was always good at them but the lack of precision and the limitations of nature made me feel powerless doing it and thus it wasn't very enjoyable.
Math on the other hand let's me explore my ideas in more depth without running into stupid issues such as: is this possible?
I'd like to do research or some comfy software dev

Is smoking being ridiculously bad for you just popscience? /sci/ is supposed to be for smart people but they insist that secondhand smoke is bad when it clearly isn't, especially when smoking in itself is incorrectly linked with many health problems caused by other factors.
Why do people, especially supposedly smart people, buy into this? Most smokers can suffer a small number of health problems...

>>7781565
what an absolute camel shagging wife beating gypsy peasant you are
shut the fuck up and stuff that ciggy up your arsehole
>>7781565
what the fuck is wrong with you idiots coming into /sci/ daily with this "smoking isn't bad" shit? fuck off and die from cancer already
1 - 0.9999... = 0.000...1
0.9999... =/= 1
prove me wrong
protip:you cant
This is bait.
>>7781261
it doesnt matter how many times u roll a 10 faced dice, there is one case such as 77777.... you cant deny its existence.
That is, y = (10^x - 1)/10^x, if y can be 1, then 10^x = 10^x - 1, then 1 = 0.
0.999... is just not 1, give it up
>>7781275
The probability of it being 777777... is 0. Note that probability 0 [math]\neq[/math] impossible.
Sage because bait.
Hey /sci/,
Name a single good textbook published by Pearson, I fucking dare you to try.
Hint: There are none
>>7779877
Algebra by Artin
Linear Algebra by Friedberg, Insel, and Spence
Applied Partial Differential Equations by Haberman
>>7779877
Pretty sure they have published Spacetime and Geometry by Carroll.
Really any Giancoli physics text is pretty good, despite the shekel grubbing at Pearson
I might as well give it a go.
Post whatever you are working on, share the best books for beginners and people that is interested in learning or taking engineering.
>What are you studying/did you study?

>Did you go to college or are you autodidact?
>Which books are the best for your area?
If it goes well we might have a wiki or a pastebin.

CS. Machine Learning Specialization.

Eating and breathing through the same hole is utterly retarded.
Thanks God.
>>7774450
But oxygen is the most potent electron receiver, and it is also abundant in the athmosphere. Without using it for energy, complex multicellular life could never have evolved!
Have sites like khanacademy, veritasium, minutephysics, vsauce and movies like The Martian etc oversaturated all the STEM fields with hurr durr science wannabes who'll (lets be honest here) never work in a STEM field anyway?
>>7785197
Khanacademy is just a resource for education, like a book. Retards could always pick up books so nothing is being changed.
The rest you list is simple entertainment. No one watches the martian and then thinks he wants to be a botanist. At least I hope so.
>>7785197
Does it matter? They're going to get weeded out by their second year.
