Why didn't the theia impact create a set of rings around earth instead of a moon?
It did, but it's been millions of years since then and it all stuck together after a while
>>8302682
Rings are formed by the breakup of satellites or as the remnant of protoplanetary disk. Theia impact was a totally different scenario
why don't we make human clones? surely, in places where it's legal we could clone richfags, dead famous people and so on. running a human cloning business could be massively profitable as well. and it could benefit humanity as a whole like if you clone genetically gifted smart or otherwise non-degenerate people.
>>8302668
What do you do when a fuck-up occurs and a clone turns out to be a sentient monstrosity? Still wanna kill it? But it's a human? Or is it?
Technology too primitive for it, might end in disaster. Wait at least 100 years to see cloning become a thing.
>>8302668
Mostly because the fuck up rate is phenomenally high and there's no real point
>>8302668
>why don't we make human clones?
Why would we bother? It's hard work, and it's not like there's a shortage of people willing to fuck each other.
>we could clone richfags, dead famous people and so on.
What good would that do?

Anyone know how to find the 'precise' big O for this?
[code]
for (int i = 0; i < n; i++)
{
for (int j = i; j < n; j++)
{
sum += i;
}
}
[/code]
It's one of these, but I'm too stupid to figure it out. My shit isn't adding up.
1. O(4N2 + 5N + 2)
2..O(2N2 + 7N + 2)
3. O(N(N + 1) / 2)
4. O(3N^2 + 11N + 4)/2
5. O(N2)
>>8302534
I stopped caring about computer science when I was introduced to the concept of Big O notation. What a crock of shit. If your algorithm can only be analyzed by inventing an asymptotic limit that can't exist, like some kind of computer science deity , then you are fucking wrong and the computer science is flawed.
>>8302534
They're all correct.
>>8302559
ya know, he ain't wrong
It's also O(1)
sum = (n-1)n(n+1)/6

Picture related allows to approximate the square root of any positive number.
I had an argument with two of my professors. They insisted that "sometimes" [math]R_i - R_{i+1}[/math] is a negative number
I argued that it only happens when you do [math]R_1 - R_{2}[/math] and never again
Who's right? Who's wrong?
>>8302521
What the fuck? Rn+1 will always be bigger than Rn are you retarded?
Like, what makes you think that making a number bigger will make its square root smaller?

(Seriously though can anyone explain this shit?)
astronomy is not science
its all guess work, nothing is empirical
>>8302229
This is somewhat related: https://en.wikipedia.org/wiki/Olbers%27_paradox
Also, keep in mind that although stars are very large, and there are a shit ton of them, they are also separated by vast amounts of space. Your room gets filled with light because your room is small and the light can reflect off the walls and the other objects in your room. In space, there are no walls; just a shit ton of empty space that takes years upon years for light to traverse.
>>8302229
The short answer is there's nothing for starlight to bounce off of. No air, no walls, no desk.
Do transhumanists have any empirical proof that the whole consciousness-merging singularity thing is actually possible or are they just larpers. I've heard that it'll happen in the next like 50 years and I'm very skeptical as to the scientific validity of this shit. Thanks
>>8302218
No.
The human mind is not compatible with our rudementary computing capabilities.
Anyone who says otherwise is either stupid, trolling, or too scared of death to admit it'll never happen.
>>8302226
For now or simply impossible?
Honestly I can see why it's such an appealing ideology. I mean all you have to do is survive for another 50 years and you'll become an immortal god
> actually possible
It's not physically impossible like going faster than the speed of light or perpetual motion machines, but IMO It's like how in 2001 a Space Odyssey there were moon bases etc. This was an entirely believable future to audiences in 1968. Predicting the future of technology and society isn't possible and anybody who claims they can is full of shit.
There are two yellow jacket hives in my backyard. One under my chair (pic related) and one behind a powerbox.
The chair hive appears to be an offshoot of the much larger powerbox hive. I have counted a total of 16 yellow jackets in the two hives.
The oddity is that these yellow jackets aren't aggressive. The hives popped up in late April and there hasn't been a single sting. Even when deliberately provoked these yellow jackets will not sting. The yellow jackets appear to be cautiously passive (they will 'buzz' you if you kick the chair) and even allow people to pick them up and move them.
Anybody have any guesses as to the cause of this behavior?
>>8302202
What the fuck is a yellow jacket?
>>8302209
Adding to this, just realized that they might not even be a wasp but rather something that mimics the look of a wasp to keep potential predators away. They may also be a type of wasp that don't even sting. There's been a lot of changes in wasp behavior lately such as collecting nectar and making honey since bees are dying out.
so after seeing this article of a man who is 145 years old I've been wondering if it's possible there are unrecorded humans who have lived to that age or even past it. because while modern medicine is key to our average lifespan, I believe a few lucky people throughout history could have survived a very long time, as we really don't have a "max" age for a human being, just an approximate age when shit starts going wrong in your body, if we had /bio/ I'd post it there but I wanna know your thoughts
>>8302193
>I've been wondering if it's possible there are unrecorded humans who have lived to that age or even past it.
Yes it is.
Lifespan is like Zombocom
It's all a matter of probability. Eventually there will be a fuck up that causes a vital organ to fail, but this guy might just every bullet up to the last one.
Just a heads up I wouldn't trust anything being published by news outlets from SE Asia they're constantly publishing stories about people who didn't eat or sleep or defecate since 1965.
Hey mathgeniuses, engineer here. I want to make a prank to my math teacher. I want to ask her something that's seemingly easy but it's actually really complicated.

How many of the following can you check off your list to form at least a mediocre human being?
History: At the very least, a broad overview of Egyptian, Phoenician, Hebreaic, Heroic Age Greece, Roman Republic and Empire periods, and the history of Western Europe from the Dark Ages to today. Given current world events of the last decade, special focus on the origins of Islam, it's original spread and resistance thereto, and the origins of the newer more radical movements (Qutb particularly) are well worth getting a grounding in.
I'd personally suggest supplementing the above by finding some historical reenactors in your area and/or western martial artists and/or a modern soldier up on his doctrine and military history. Not necessarily for the art itself, but to better understand the mindset of the people doing the fighting - since so much of human history has been fighting, sadly.
Economics: Smith, Keynes,Marx/Engles, Friedman/Hayek - know at least the names and summarize their views.
Literature: Work through any 101 or 201 syllabus prior to 1960 or so... the Big Milestones are usually Beowulf, Chaucer, a couple Shakespeare plays and sonnets, maybe Milton or Donne or Spencer.. then a couple Romantics like Byron or Blake, and a 19th c. novel or three. I'm not overly fond of Dickens, but he was popular and gives a decent feel for the age. Maybe Doyle would be more fun. :~
Humanities: "History of Art" and "History of Music" 101 level.
In both literature and the humanities, I'd definitely stick with canons put together prior to the PC era. Not because there aren't great and important works done by people of all manner of minority status, but because you're looking for fundamental milestones in the art - and modern canons frequently give short shrift to the latter so as to give more time to the former.
I'd also add - have at least one means of artistic expression. Doesn't matter if it's playing Blues guitar instead of Classical violin, or drawing Manga instead of Renoir copies, but have at least one artistic hobby. Just 'cause.
Law: don't know enough to give an opinion. But Roman law and the origins of Common Law (plus if you're American, a good working knowledge of the Constitution and the arguments on both sides leading up to it, along with being able to list the Bill of Rights (if not recite from memory)) should be in there.
Medicine: basic anatomy and first responder level of medical treatment
Physicality: Practice at least one sport or other physical endeavor... better if it has a cultural history with big names to know (be it Owens or Musashi) - but at least something.
