if heat rises, why is the upper atmosphere cold?
Parts of the upper atmosphere are warm. It's complicated.
>>8778645
it rises too high and gets sucked into space

Heat does not rise.
Heat radiates.

Can someone explain the Bogdanoff affair to me? How were two guys so easily able to troll the scientific world and get PhDs by bullshitting? How do I know that many other people didn't bullshit their way to PhDs as well?

What I'm so surprised about with these niggers is their hair. These guys obviously care about how they look (whether or not you think they do a good job of that is irrelevant) yet they both have horrible, dry, damaged hair that looks like shit.

I came across this star gate project recently, which is as I understood it basically a bunch of testings held by CIA to research remote viewing.
https://www.cia.gov/library/readingroom/search/site/Star%20gate
A lot of them were successful actually and CIA saw some potential to it.
It makes me wonder why most people claiming they have "abilities" look like bullshit artists and can't do shit and why doesn't mainstream science pay more attention to things like this.
Just because the results are statistically significant, doesn't mean they're useful. What we consider a "small" amount of information is actually a shitload of information, and remote viewing can only acquire truly small pieces of information. We also can't really "look into" it until a mechanism for the process is isolated.
If somebody were to try to study it anyway, I think it would be better to look into precognition and telepathy(read only). If you read about project stargate, it at some point mentions that these two things are just remote viewing with a different type of target. The thing is though, the information you get from remote viewing tends to be more "abstract" because it doesn't set a boundary on the thing you are trying to see, so you get information from a bunch of different angles, which the human brain isn't use to dealing with. With telepathy and precognition, your brain is basically just mimicking the structure of another brain(precognition is reading the mind of your future self), so it will tend to stay within a more "digestible" form.
It should be noted that telepathy can't really pick up "thoughts" because they are very weak patterns. Reading a mind is taking an extremely brief slice of somebody's senses and their body's motions, then copying it onto yourself. If the target is moving around when you do this, it causes your body to jerk as though to copy their motions. I would hypothesize that a "good" target for telepathy is one that is very active, because they produce more "distinct" patterns and thus their is a more concrete indication of success.

meme-tier with NO credibility
How to be CIA:
1. be really secretive about most things so that everyone, including your enemies, are interested in what you're doing
2. Occasionally "leak" documents or otherwise reveal "information" about your organization. Most, if not all of this "information" should be lies, so as to confuse your enemies.
3. ???
4. Become shadow gubmint
I have a hunch that the documents about the CIA having remote viewers is just a ploy to scare enemy spy agencies. Enemy spies could become fearful of almighty CIA remote viewers, or they could fruitlessly invest time and resources into developing their own remote viewers. In all likelihood, the CIA enlisted the help of a science fiction writer to forge some documentation about ESP technology. That's what those documents sound like when you read them - science fiction.
Why aren't more of you scientist becoming entrepreneurs? Is it secretly because you have weak hearts? I know you have some bad ass invention ideas too baka.

Hey /sci/, i've got a really interesting problem for you.
If you have a standard 52 card deck, and you lay the entire thing out face up (assuming its been perfectly randomly shuffled), what is the probability that any random deck will have at least one sequence of at least 5 cards that are the same color (black or white).
Ive solved this using a simulation in MATLAB, and I got around 93% of all decks will have at least 1 sequence of >5 cards following this rule, but im wondering how to solve it using regular combinatorics.
If anyones interested I can post the code.
>>8773025
Whoops, I meant Black or Red. Sorry about that
I'm not going to do your homework for you but I'll help you out.
If you break it down you have a finite number of reds and blacks (26 each) and you start by laying your first card down it's a 50/50 chance it will be red or black. Now you have 51 cards cards (26 of one and 25 of the other) and what happens is as you deplete the cards the likely hood of certain streaks increases and those streaks will weigh against the remaining cards resulting in a rather high probability of a sequence of 5+ cards in a row.
50%

Do you believe humanity will ever colonize another planet? Another solar system?
Do you believe humanity will ever survive long enough to reach that point?
How do you think humanity would approach the colonization attempt? Small crew with embryos and artificial wombs or larger passenger vessels?
Do you believe that the majority of labor in a colonization attempt would be primarily automated or would the human element still remain?
Which nation is currently the best contender for first successful space colonization?
What do you believe are the biggest problems that we face when it comes to space colonization?
Would you be willing to join a space colonization attempt if the destination was a rather featureless planet like Mars?
What are some movies involving space colonization, either the journey there, the initial colonization, or years after?
>Do you believe humanity will ever colonize another planet? Another solar system?
I would say 100 years for mars and our solar system in general and 200 years for outer solar system stuff, but both times pretty limited first unless we can find way to make it profitable (Space mining).
>Do you believe humanity will ever survive long enough to reach that point?
Unless a nuclear war happens, I`m pretty sure we will reach that point
>How do you think humanity would approach the colonization attempt? Small crew with embryos and artificial wombs or larger passenger vessels?
A mix of both,
>Do you believe that the majority of labor in a colonization attempt would be primarily automated or would the human element still remain?
The human element will definitly remain, but very much stuff will be automated simply to drive down labor cost
>Which nation is currently the best contender for first successful space colonization?
Currently the US and PRC if we talk about single nations, but considering how far in the future it would be, I wouldn't be surprised if it will be some african transnational space agency.
>What do you believe are the biggest problems that we face when it comes to space colonization?
Establishing a proper biosphere and the communication delay, especially outside the solar system.
>Would you be willing to join a space colonization attempt if the destination was a rather featureless planet like Mars?
Sure, it would be madness not to join such a project.

Now, good goy, please learn more mathematics so that you understnad that the shape of the world is actually spherical I fucking swear.
Yes, I fucking swear. If you just walk in one direction you will just reach the same point. You will definitely not reach the edge of the earth where god will meet you and give you your yearly allowance so that you, the true jewish religion, can live above everyone else.
Indeed, that is ridiculous as there is not even an edge of the earth!

Last day of Spring break here, and my email is already blowing up about how I made a grading mistake and they had the correct answer. They're even attaching pics of their tests to the emails. HAHAHA our department policy is to scan and copy every exam before we grade it, and guess what? They're changing their answers, so 5 out of 7 that have emailed me. This should make for an interesting week since we are way past the drop deadline and our policy is automatic F if caught cheating.
On a related note, it will be nice to get back into the swing of things. I have a result that might be publishable so I am keeping my fingers crossed when I meet my advisor later this week.
My field is statistics.
How was everyone elses Spring break?

WHY do you want to advance science?
Do you even know WHY or are you just a machine following orders from your environment?
Curiosity, There's so much we don't know. Finding out what that is gives us meaning.

I have been intenesely curious about how everything works since I was a child.
I can't wrap my brain around the idea of people who lack curiosity.
Is there any good reason why this wouldn't work?
I want to run for office in a decade on a pretty bland populist platform, and want the space elevator to set me apart.
it works on paper. the build challenge is finding a light enough material with the strength needed.
carbon nanotube or graphmeme can do it. yet if you place one atom wrong, you lose significant strength. after so many wrong atoms the whole thing is useless.
you have to place it on the equator. South America is the only place stable and secure enough to put it. Africa and SEAsia, not so much. Pacific Islands are out because none are big enough.

Orbital debris will cut the cable.
A space elevator would be under enormous tension and would need to be almost atomically precise across its entire length in order to be strong enough. A fleck of paint or grain of sand moving at low Earth orbit speeds would hit with a relative velocity of nearly 7 kilometers per second, and cause significant damage to the cable. The damaged cable would not be able to handle the tension forces and therefore would snap.
The only options are to either overbuild the cable by a ridiculous amount, making it way thicker and heavier than necessary, and thus making it much more expensive and difficult to build, or you could attempt to track every piece of orbiting material larger than microscopic and use some kind of active defense system to vaporize the debris before it impacts the cable. Both are pretty bad options, but you can't go ignoring the problem and having your cable be cut after a few weeks or months of it being up, every time you put it up, if you're lucky.
Space elevators only really make any sense aroudn very small worlds with low gravity and a fast spin, needing only a short cable and not requiring ultra-strong materials (although we'd use them anyway just for the margin they provide, because space debris would still be a problem there as well).

not him, but you have 3 basic shapes, circle, triangle and boxy. look at flips around the horizontal and vertical axes. you have the complete circle, the circle flipped around two vertical axes, and then one with one half flipped. if you pay attention though, the right half that circle is also flipped along a horizontal axis. that explains the weird triangle shape. the top right square is the only one that fits the pattern for the others.
