What was the name of the drive and company that only just recently had a propulsion system launched into space for testing for the first test in space to see if it would produce thrust? It was very recent, last month I think

Alcohol helps to 'reset' my brain. I get to a point where I can't carry on. The pain is too much. The noise in my head is too much. The distress is too much. The confusion is too much. This goes on for days/weeks/but normally months until I can't take it any more and can't get through another day like this and I drink and fall asleep. When i wake its like my brain has reset itself and i can carry on. I can keep fighting. I can keep going. I have no idea why this happens or why I experience things like this, but I haven't yet found anything else that helps like alcohol does. Of course there are negatives as well which is why I'm trying to stop and stay stopped but wondered if explain this experience of 'reset'? I'm 89 days without alcohol.

Do CS students share classes with math undergrats in your cunt?
In Germany at my local university, we share

1st Semester
- Analysis I
- Linear Algebra I

2nd semester
- Analysis II
- Linear Algebra II

3rd semester
- Statistics

4th semester
- Numerical Math
- math as a choice class (you don't have to)

5th semester
- math as a choice class (you don't have to)

it is even possible to just get a math degree as a CS student here lmao

I feel like in other countries CS is less about math, is that true?

How would I prove that a bag of chips is filled with pure nitrogen?

2 replies omitted. Click Reply to view.
>> No.15899676

You're trusting that the description of solid weight content on the bag is accurate.

>> No.15899822

Weigh the bag. Empty bag, weigh chips. Find the volume of the bag without chips. Calculate the mass of air/nitrogen in that volume. Then sum the weights to see if it is air or nitrogen.

>> No.15899848

Now you're still assuming that the weighting scale is correct and that the reference for the mass/volume of nitrogen is correct. Your definition of true/false is limited to this network of references. I'm not OP by the way and he may have used this example as a metaphor to depict black box systems like humans.

>> No.15899863

You can make your own weighting apparatus. It's easy. But since these are reference based, you can start by using your fav rock, without any dependence to metric system.

>> No.15899887

In other words: consistency is key. Things must relate consistently in the same manner. That leads to the replication crisis: how many times have you measured the mass/volume of nittrogen to be sure what that is? Now we get a bellcurve distribution of m/v nitrogen.

The whole "It's impossible to domesticate zebra, Africans would have if it was possible" is the biggest bullshit. I cannot believe this shit gets sold as actual science. Domestication is just taming an animal and then breeding it for generations. Petting zoos all over the world have tame zebras. Movies use tame, trained zebras. There is no animal on earth that cannot be domesticated given enough effort

the true advantage a schizo possesses over others is an innate fluency with the nature of paradoxes
inevitably, when you reduce a truly hard problem down to its smallest kernel of dysfunction, you end up with a paradox
a paradox is in effect the de facto fundamental particle of the science of hard problems
therefor the intuitive understanding that schizos possess allows them to comfortably exist in a world where no true resolution of absolute objective fact is ever possible
