So you put your coin on any number of your choice on this roulette wheel.
>After betting (again, a-f-t-e-r betting) you have 1 chance out of 36 to win singles, right?
>Let's ignore the green '0' in this scenario.
>Half a minute earlier when you came up to the table, you had to make a choice, this number, that number, or this here number out of the 36.
>One number out of 36 to choose, and one chance out of 36 that your number comes up.
>So from that exact moment half a minute ago when you d-e-c-i-d-e-d for your number, did you have.....
>1 chance out of 36 times 36 = 1 chance out of 1296 possibilities to win,....
>or did you have just 1 chance out of 36???
>Again, this is at the exact time when you d-e-c-i-d-e to play, before you even placed your bet.
This is no trick-question, I just can't find an answer that is better than the other. Does /sci/ know?
.... So, help, or something.

Before you bet, you had no chance of winning, as you have not placed a bet, you fucking moron.

So you just decided to be a dick, huh?

Lexicographers are trying to change word Orientate to Orient, which I think is a mistake; Orientate is not attention to east - but a salute to the east, in terms of semantics.

Orient is a false word if it is to replace orientate, but can serve as a different word.

False Orient definition:

align or position (something) relative to the points of a compass or other specified positions.
is said to replace Orientate

to aim something at someone or something, or make something suitable for a particular group of people:

Orient is aligning self to compass and Orientate is aligning self from compass.

Like a focused shaking of the head from left to right.

Profile freeze of character and activity.

Smiling and other relax process to be critiqued.

You forgot to take your meds today didn't you?
>>
i oriented myself around the compass

It sounds good, but it's nonsensical, it's not correct grammar. This false sentence which can be corrected supports similarity between orient and orientated.
>>
Lexicograpehrs don't try to change words and if they do they are stupid. They observe the words how they are used and then document that in dictionaries. If the meaning of the word has changed in public usage then it's pointless to hang on to an outdated definition.

Can someone explain why /v/, /pol/, and /r9k/ are more popular than /sci/? I'm a first timer on this board and it's really slow.

Science and math aren't as popular in general as video-games, politics, and meme spouting are.

As a general rule, though, on 4chan the less posts per minute a board gets the higher quality the posts are.

If FH launches successfully I'm switching sides. I was a dedicated "SpaceX BTFO" guy as well but NASA has let me down for the last time. Space Shuttle - flop, Constellation - flop and now SLS - flop. They should just shut down everything except JPL.

NASA shouldn't be making rockets. They should make probes and play around with experimental propulsion systems.

The new anti-science administration gutted their budget, what do you expect? Wait a few years until the republicans go away and then you'll see some actual work being done. Though at that point the damage everywhere will be so massive I'm not sure fixing NASA's budget would even be a secondary priority.

I've been saying it for years. Women were a mistake. Women should be kept captive in prisons where men can come in and rent and or buy them.

That way if Elon wanted her, all he had to do was go into the prison and buy her. Then when the bitch gets crazy he can just kill her or sell her, as she would be his property.

It is not too late americans. We can still change the laws and make women cattle before it is too late.

Are Dyson Sphere's Theoretically Possible to Build?

If you could keep the panels from getting incinerated, then I don't see why it wouldn't aside from the risk of screwing up the earth's climate, though transparent panels would probably solve that problem.

Why Are You Capitalizing Every Word You Mongoloid?

Not only are they possible, they're inevitable if humanity ever gets off Earth and doesn't discover some unknown power sources. Pretty much as soon as the first off-Earth colony is built the construction of the first Dyson sphere will begin. Dyson spheres aren't really rigid structures like your picture portrays, they're more of a cloud of objects, your picture would be better described as a Matrioshka brain. They could be, but there's not much point in building an actual sphere. But yeah, its not a question of "if", if we ever leave Earth they definitely will be built since there's more than enough material lying around and letting all the Sun's energy go to waste is pointless.

Hi, /sci/!

I need your help.

I have this really shitty brain, so I have a hard time studying.
pls, somebody tell me how to get high quality adderall without getting caught by the police (it's illegal in my country even ritalin).
I have heard it's really cheap and high quality in India is it true?

I'm really desperate and I hope you will help me.

Why do so many otherwise "logical" people say that it's likely there is life on other planets?

Given the data that we have no one can make that statement. No one knows how rare life is to create, we only know of 1 example of it ever occurring so far.

You can not logical extrapolate from this data no matter how big the universe is. Life could be incredibly rare, the only reason we know of this occurrence is because we're part of it.

It could also be relatively common as well, my point is you cannot actually say anything about it logically.

There are ways to estimate probability of something happening other than raw statistical measurement. In this case, the estimates are based on a detailed understanding of biology and biochemistry.
>>
People who describe themselves as logical are usually not very logical.

Also, the average person's opinion on whether there's life out there is worthless. In fact, so is every expert's opinion. Until we know exactly how life appeared on Earth, which we don't yet know, we can't say how likely it is that it appeared on other planets.

No one understands biology and biochemistry to the point of knowing how to create new life from no life.

Freshman math major here. Grades for pre-Algebra just got posted. I made an A, highest grade in the class. Ready to take on College Algebra this summer.

What is that math with the big sloopy 'f' and that uses the variable d a lot? What year do I take it?

That's Real Analysis. You won't take it until your senior year. It only has a 20% pass rate for the first time taking it. My first time taking it, there were only 5 people in the class and it only some Asian girl passed it and got a 100.
