Is It possible that at some point before the age of mammals there could've been some sort of civilization during the age dinosaurs? I mean they were around for about 65 million years and we've only been around in a civilized state for over a few thousand years.

I'm guessing enough time has passed that entire civilizations remnants would have disappeared by now.
Thoughts on this?

They don't appear to anatomically equipped for it. Our predecessor species had tools, fire, cooking, clothes and more. Us homo sapiens inherited all of that. It means such things are pretty much intrinsic to us as a species, part of our biology, just as language is. No others seem to display the requirements or indicators of a civilisation or a species able to create civilisation.

Taking real analysis and abstract algebra in the fall, how blasted will my ass be - edition

Hello, can anyone give me a reference to a book or some other publication that states the problem in this math exchange question:
https://math.stackexchange.com/questions/2058905/limit-of-complex-line-integral-over-a-uniformly-convergent-sequence-of-curves

Perhaps someone who knows complex analysis and knows a lot about the literature? I need to find a precise statement, as the comments suggest that the asker did not express the problem correctly. but then they are vague as to what is missing and how to prove it. Please help, I've been looking for days.

> Elon Reeve Musk (born June 28, 1971) is a South African-born Canadian-American business magnate, investor, engineer, and inventor.

> He is the founder, CEO, and CTO of SpaceX; a co-founder, a Series A investor, CEO, and product architect of Tesla Inc.; co-chairman of OpenAI; founder and CEO of Neuralink. He was previously co-founder and chairman of SolarCity; co-founder of Zip2; and founder of X.com, which merged with Confinity and took the name PayPal. As of May 2017, he has an estimated net worth of $15.2 billion, making him the 80th-wealthiest person in the world. In December 2016, Musk was ranked 21st on the Forbes list of The World's Most Powerful People.

> Musk has stated that the goals of SolarCity, Tesla, and SpaceX revolve around his vision to change the world and humanity. His goals include reducing global warming through sustainable energy production and consumption, and reducing the "risk of human extinction" by "making life multiplanetary" by establishing a human colony on Mars.

> In addition to his primary business pursuits, he has also envisioned a high-speed transportation system known as the Hyperloop, and has proposed a VTOL supersonic jet aircraft with electric fan propulsion, known as the Musk electric jet.

Is he legit?

If his achievements aren't enough to answer that question I'm not sure how to convince you that he is. He's more of a businessman than an engineer if that's what you're asking, I doubt he does any kind of engineering work.

According to his interviews he spends about ~80% of his time on engineering and works around 80 hours a week. If he spends 64 hours a week on engineering work then he's more of an engineer then your faggot ass.

Can anyone explain what the computer simulation theory is all about? Like, what does it mean to me, as an average Joe? Will I wake up into an advanced civilization when I die? If I ask please, will the people running the simulation let me run the simulation again, but as a rich ass playboy? Seriously. Please explain how it works exactly.

Why have we been getting more and more disturbing anomalies in our Magnetosphere?

>>9020086
Its not a conspiracy theory. The Earths magnetic field has flipped many times throughout history. This is fact, as evidenced by ice core samples dating back many thousands of years, and is not up for debate. Looking at the history of Earths magnetic flips we are long overdue for another one. Its not a question of if, its a question of when.

>>9020238
now what causes it?
Naturally occurring phenomena of magnetism? Something we don't yet understand about planetary dynamics?
Or something else?

So my teacher told my class today that, in an spherical plane, "lines" parallel at one point eventually converge.

It blew my mind, I can't understand why. Lines sorted like latitudes on earth are actually parallel at all points and never converge. Can someone explain this to me? I know my teacher isn't wrong cause I googled it as soon as I got home but I have no clue what I'm missing.

>>9020052
it's because the lines have to be greater circles
>>
>>9020052
Latitude lines are constantly curving to be what they do. They're sorta parallel or at least their tangents are but those tangents would intersect
>>
>>9020052
There are no lines on a spherical plane. At best the tiniest portion of a line would touch the plane. Remember, lines are straight, if they are not straight, they are something other than lines.

Feels bad that I'm not more intelligent and that I'm some feeble-minded normie who will never be able to attain a P.H.D and contribute valuably to science.

I love the field I mentioned with a passion, but will I ever be "good enough"?

I know what I'm pursuing isn't physics or engineering but is my IQ enough to become a molecular biologist and excel at my field?

Will I struggle in college?

I wish I had a gifted level of intelligence. Hopefully brain implants will give me a game changer one day...

If you're legitimately interested in something you will find a way to learn about it at least to an undergrad level.
There is no need to worry about IQ unless you want to be a leader in your field.
I'm guessing that if you're here asking this question you're probably not going to the most prestigious university for what you desire. Just remember you will only succeed in your field if you actually are interested in it.

>There is no need to worry about IQ unless you want to be a leader in your field

I don't care about that, I just want to be good enough at my job to contribute to the field

Yeah, neither rich nor smart enough for that.

Write out grad u in terms of partial derivatives of u. Equate that to A. This gives three differential equations you can solve.

is that cross product what the hell is this notation
>>
>>9019163
First you have to make sure that the rotation of A is 0 so
a = 3
b = 1
c = 0
then it becomes simple integration:
U = 2 x^2 + xy + 3xz - y^2 + z^2 + C
