Nice job making yourself look stupid as hell. I actually left my hometown to get educated and see the world while you continued to live in some hodunk countryside while your company abuses your body for manual labor (he had a workplace injury). Is this what it’s like to be poorly educated? Living a shit life and just talking down others to reaffirm yourself?

How can I determine the molecular density of a solid? My goal is to ensure that two particles of different substances are a similar weight and size.

mars power

No.10306690 ViewReplyLast 50OriginalReport
Reminder to all redditor spacebrainlets that solar power on mars is IMPOSSIBLE. Nuclear is the ONLY way and that's why NASA is working on it.

Calculations from this video https://youtu.be/X__AKRqlK4s confirm sunlight is reduced to 0.00002% in dust storms that last for months meaning your panels are absolutely fucking worthless and anyone relying on them will die a horrible death.

100kw/h power will be reduced to... 2 watts. Yikes.

Even square miles worth of solar panels won't produce enough power for few lights so good luck with those top lel.

Grothendieck's Notebook

No.10314009 ViewReplyOriginalReport
Apparently Grothendieck is said to have written new results in his previously unpublished notebook. Mathematicians have said it would take some time to go through it and said it is hard to understand even with modern math.

Who here can read French and understand it?

Hey /sci/ brainlet here,
are the 3 axioms of a metric space really just axioms or can they be proven from within set theory or something?
