At 25 would it be too late for me to learn math and science so I can contribute in a significant manner? I only know functions and basic calculus like rate of change and the slope of a tangent line. Stuff like limits allude me if I try to explain them to somebody else.

Lets say in 500 million years another intelligent species evolves. Is there anything chance of the knowing humans existed?
What of ours would make it that long into the future? Maybe our plastics and fossils?

So technically speaking, wouldn't Calculus 2 be considered the hardest course a computer science major has to take? cal 2 is considered the hardest math in undergrad and computer science courses are pretty simple unless the professor is a dick and wants it to be hard.

>Mathematics Requirements in Computer Science
>While nearly all undergraduate programs in computer science include mathematics courses in their curricula, the full set of such requirements varies broadly by institution due to a number of factors. For example, whether or not a CS program is housed in a School of Engineering can directly influence the requirements for courses on calculus and/or differential equations, even if such courses include far more material in these areas than is generally needed for most CS majors. As a result, CS2013 only specifies mathematical requirements that we believe are directly relevant for the large majority of all CS undergraduates (for example, elements of set theory, logic, and discrete probability, among others). These mathematics requirements are specified in the Body of Knowledge primarily in the Discrete Structures Knowledge Area.

>We recognize that general facility with mathematics is an important requirement for all CS students. Still, CS2013 distinguishes between the foundational mathematics that are likely to impact many parts of computer science—and are included in the CS2013 Body of Knowledge—from those that, while still important, may be most directly relevant to specific areas within computing. For example, an understanding of linear algebra plays a critical role in some areas of computing such as graphics and the analysis of graph algorithms. However, linear algebra would not necessarily be a requirement for all areas of computing (indeed, many high quality CS programs do not have an explicit linear algebra requirement). Similarly, while we do note a growing trend in the use of probability and statistics in computing and believe that this trend is likely to continue in the future, we still believe it is not necessary for all CS programs to require a full course in probability theory for all majors.

can anyone convince me that the moon landing was real?
i dont believe conspiracy theories, but the moon landings are clearly fake. im surprised how People can actually believe it.
the Cold war was at its peak, and this achivement was the thing that could "win the race".
and when it comes to the evidence, its just too much to even dive into.
the one thing that 100% convinced me that its fake, is the lack of stars.
NASA said it was because of the bad image quality, but even in the high res photos, you see no stars. and the crew had a high quality color-filmcamera With them, but they never recorded With it on the moon?
on later missions they even brought a car.

oh, and the plans for building a New rocket powerfull enough for the trip, are gone. the scientist who knew them died.
look it up. thats what they said.

and the Whole thing didnt need many People to cover up.
you send some guys into orbit or something.
you send fake data to all the workers.
and only a handful of People know about it.
oh, and nasa lost all the data With the positioning.

somepne please give me a reason for why they landed. i just cant see it.

thats not what NASA said. they said it was because of the low quality film.
even footage from the spacecraft shows stars.

i can even see a few Bright stars during the day here on Earth.
is the moon as Bright as we see it from Earth, or as Bright as in the NASA Pictures? because thats 2 way different brightnesses

INTP here.

I think it describes me very well.
I am generally introverted.
I am very good at math so you could say intuition is my talent.
I tend to think a lot.
I am good at prospecting.

For random variables I am trying to understand what the below equation means:

Pr[X=v] := Pr[X^-1(v)]

Is it basically saying the probability of v in set V is the same as the probability of falling into the pre-image of v in set U?

Launch is at 05:26AM UTC (01:26AM EDT)

The payload is a KU/KA-band geostationary satellite. It's a heavy bird, so 1st stage landing will be quite difficult.

Has depression or any other mental illness gotten in the way of your studies?

What was the result?
89 posts and 4 images submitted.

>>8269483
If you just reject depression it simply goes away.

It's been proven pretty much that depression ages your body - damages your cells.. it's more physical that we thought.

So why the fuck would I want to go trough that - just reject it and it will be gone, do not accept it under any condition - stay happy.

I haven't meet a person who can't do that naturally if he actually tries - only people that enjoyed being depressed because they brought it into social circles and in their mind they thought it was eccentric or something.

"The lack of new physics deepens a crisis that started in 2012 during the LHC’s first run, when it became clear that its 8-TeV collisions would not generate any new physics beyond the Standard Model....... theorists are increasingly bracing themselves for their “nightmare scenario,” in which the LHC offers no path at all toward a more complete theory of nature."

"Some theorists argue that the time has already come for the whole field to start reckoning with the message of the null results. The absence of new particles almost certainly means that the laws of physics are not natural in the way physicists long assumed they are. “Naturalness is so well-motivated,” Sundrum said, “that its actual absence is a major discovery.”
