how do i prove given any integer X that X,X+2 or X+4 is always divisivle by 3?
>>7662724
think about what numbers are divisible by 3 and their relation to each other.
By way of contradiction, I'd wager
>>7662724
Given an integer X, we can consider its remainder when divided by 3. This remainder can only be 0, 1, or 2. That is, there exists an integer k such that X = 3k, X = 3k + 1, or X = 3k + 2.
Case 1: X = 3k
Then X is divisible by 3.
Case 2: X = 3k + 1
Then X + 2 = 3k + 3 = 3 (k + 1) is divisible by 3, as desired.
Case 3: X = 3k + 2
Then X + 4 = 3k + 6 = 3 (k + 2) is divisible by 3, as desired.
I'm about to fully submerge this (glass) bottle of chocolate milk into boiling hot water for 20 mins.
Is it safe?
yeah, for a bit at least
>>7662681
Are you looking to heat it up for a good reason or are you just having a larf?
>>7662686
I'm trying to replicate the taste of Cocio. They claim that they submerge their bottles, caps on, in 100 degree water for 20 mins.
The boiling point for milk is higher than that of water, am i right? (=will it even cause pressure inside the bottle?)
What is the relationship between intelligence and creativity? Which is more important to an engineer? Can one be successful as an engineering, in the sense of creating something novel and functional, without being a top student?
Every developed discovery has been entirely novel. Newton exhibiting great creativity during the synthesis of observation and mathematics during his development of calculus back in mid 17th century England. Especially during the bubonic plague.
Ask all engineers and you'll find a mix of answers.
Depends on what success means to you bloke.
>>7662642
Creativity is the rafined form of imagination that is necessary for some fields, other than that it's absolute useless as imagination is.
Intelligence does not have a direct relationship with your creativity, with your imagination.
You can live all your life in the cold reality as it is without imagining anything and still discover something that will change out the course of reality.
Imagination is really a disease of human brain.

yes, i had many stupid moments

no, its because most new ideas are trash and most people are fucking morons

>Terrified of his own eventual death, obsessed with immortality
As an atheist I've come to terms with death. I do not care about when my conscience ends.
>Poor diet, does little exercise
Unfortunately true but I'm trying to increase the amount of exercise I do. And I am not fat, actually pretty skinny. Doing exercise to get muscle.
>Believes himself to be a genius
I won't believe myself to be a genius until I prove a new theorem that changes mathematics forever.
>Is only good at one narrow subject field and not even anywhere near the best at it.
We can only do one thing in college right? Unless you are autistic and do double-major. But my university psychology test said that I'm good at learning and applying that knowledge pretty fast so in theory I could succeed in many things.
>Used to be full of "clever" ideas as a kid
I do not remember. Probably not.
>Now attacks any new ideas because his own childhood ideas were trashed.
Completely false. Nobody does this.
>Claims to not care about money
I only care about getting enough for my own needs. That is why I'm unnafected by faggots who claim that they are better than me because their meme degree will pay them more. But obviously money is pretty important if you do not want to live a shit life.
>Laughs at non-STEM graduates for being "unemployable"
I only laugh at gender studies types who are literally unemployable. Even an artist can succeed and I admire many artists myself.
>Claims to be an engineer after two or three years in university
Not an engineer. But I do not claim to be a mathematician because I am just a retarded student, no where near to the geniuses of my field.
>Never actually designed anything, can barely even use CAD software.
Like I said, I'm not studying cad-monkeying. I mean, engineering.

>Has no evidence that there is no God but believes so regardless
I choose my believes. Arguments that assume that there is no god are more consistent than arguments that assume that there is. This is specially true for religions like Islam and Christianity that are so inconsistent that there is no one "christianity", there is a fuckload of denominations because of how inconsistent it is.
>Looks down on those who have no evidence that there is a God but believes so regardless
I do not look down on anyone who is a good person. Christians and muslims that do not do suicide bombings are good people. I do not criticize believe unless they use it as fuel for harm.
>Doesn't believe in aliens
I believe the possibility of aliens existing is pretty high.
>Disdain for pop-sci
Not for popsci but for people who like popsci. These people just memorize a bunch of vsauce videos and then talk like they are experts. Like when a 12 year old comes here to talk about quantum mechanics and he cannot present well argumented opinions because he hasn't even done a quantum mechanics 101 for babies class.
>Pop-sci is where he got all his knowledge on relativity and quantum mechanics from
That is true for me but that is because I am not a physics student. I also get knowledge from what other anons post here but I am actually not interested in quantum mechanics or anything related to physics. Pure mathematics is way more appealing.

Which would be more interesting, but sadly, no, that guy really does just suck hard at math.
How is mathematics (specifically algebraic topology and algebraic geometry) applicable to the construction of goat towers?
>>7662602
You can use functional analysis to calculate a goat tower which provides maximal enjoyment for the goats.
>>7662602
You can use knot theory to construct cool staircases for the goats
>>7662602
You can use mathematical logic to interpret the profound wisdom contained in the sayings of the goats.
What are the implications of a toroidal shaped planet. How could a toroidal planet be distinguished from a spherical planet by inhabitants without going into outer space?
their planet is toroidal not their spacetime
they would be able to see the rest of the planet just fine unless it was cloudy or something
>>7662584
What if the "inner" part of the torus is just ocean or uninhabited?
>>7662582
>What are the implications of a toroidal shaped planet.
The "implications" are probably that it would collapse into a sphere at once. If it didn'r, then the implications are that magic exists and is used to keep the planet from deforming.
>How could a toroidal planet be distinguished from a spherical planet by inhabitants without going into outer space?
By exploring and mapping it.
Also if the toroidal planet was oriented such that the interior surface gets enough light to be habitable, one side of the interior would probably be visible from the other.
How does an average day look for a working:
>Chemist
>Physicist
>Mathematician
>Engineer
?
>>7662507
I am in software engineering (my degree is in EECS - Course VI at MIT). In my average day I get up, get coffee, go to my job, and have a boring meeting with my boring manager, whose name is Rob. Rob generally says some bullshit like "You're very diligent but your output stinks. Your code is not functional or elegant." I think he's an idiot who should probably just write the code himself, but I don't say this out loud because I am not crazy. Then I code some more and drink some Tab and Mountain Dew. Sometimes I hang around the front desk and flirt with the receptionist, telling her that her sweater looks nice, offering to buy her a soda, and bring her a cup and ice. She generally declines, because she believes that soda will make her fat and she tells me that she is busy with the telephone and has no time to chat. So I walk back to by cubicle and sit down and pretend to work. Honestly, my job is not fulfilling or creative.
>>7662513
>drink some Tab and Mountain Dew
Nice meme.
Also software engineering isn't engineering this thread isn't for you.
>>7662520
I have a degree in EECS, an SB (Scientiae Baccalaureus) in Electrical Engineering and Computer Science. It is an engineering degree.

What does the stuff inside the barrels look like? Google searches only return pictures of the barrels, not the contents
Try "spent nuclear fuel" instead. There's probably other stuff in there too like reactor components.
>>7662374
The fuel itself is just metallic looking rods in various states of corrusion so they may be grey-ish or whitish as well rather than shiny. Other items in the barrels can be contaminated building materials or soil, so bolts and nuts, odd metal bits, and dirt.
The barrels are often topped off with an anti-corrosive, neutron modulating liquid, but it depends on the contents, really.

Why is our world the only one within our solar system not to be named after a Roman or Greek god or goddess?
Also, please tell me that NASA has plans to launch a probe or a rover to Pluto in a short amount of time?
I really want to see the surface of this dwarf world before I die and if NASA launches a mission in the next couple of years it might be possible. Doesn't it only take about nine years to get there?
>>7661805
>Why is our world the only one within our solar system not to be named after a Roman or Greek god or goddess?
Because to the Greeks and Romans the planets WERE the gods. I guess if you want a god for the earth you could use Terra, that's Roman.
