It can, but the probability is overwhelmingly small.

You have a near infinitely higher chance of having the window partially tunnel through the fly and killing it.

Why are French people so good at mathematics?
38 posts and 7 images submitted.

I never heard that stereotype. I know it's true for russians because their educative system is more math oriented than others, to maybe it's something similar in France

Germans and Russians (specially the ashkenazim) are better.

France is so boring that mathematics is a popular form of escapism, although not as popular as being drunk or fucking boys.

How do you power a base? Solar, nuclear or both?
86 posts and 27 images submitted.

nuclear, solar will get fucked by sand storms.

Reddit said that solar is about 2/3 as effective as on earth. Further away from sun bad. Thin atmosphere good.

>>8764924
Would likely be determined to some extent by availability of resources on Mars, for a base of long term sustainability and size. Obviously, solar will suffer from distance, but if resources for it are abundant, there is plenty of room at least.

This is an old line of thought from his blog and from a casual text he wrote years ago.

It's actually probably the non-mathematical writing I like the most (the worst being the Hillary shilling).

It's valuable because a lot of guys don't understand that rigor and formal logic isn't the end state of math, or that math in practice doesn't look like the field of logic of theoretical computer science. Let alone that most mathematicans probably couldn't name 5 of the 10 or so axioms of ZFC.

You'd get mad if you were to use the scientific method in real life to find "truths".

You can of course do experiments and find stuff, but the truth of it would be so weak it's totally irrelevant, the world is way too vast to use the scientific method in a non retarded way as an individual.

Conway's Game of Life should be the most popular CA but there's a lot more to it.

It is a good way to understand the numerous possibilities of Turing complete CAs.

I think they're cool, I thnk that kids should be exposed to them at a young age considered how easily they are defined and convey very well the message thay simple rules can lead to very interesting. I also think Wolfram went a bit too far and forcifully tried to build a whole philosophical system around there without really much scientific to say...

When did you get redpilled on the career prospects in science?

Out of my graduating class of mathematics bs, 3 years later all either ended up in retail or working as teachers.

The few that went to graduate school, myself included are the only mildly successful ones.

The War on Biological Science continues. This thread is for discussion of the science of genetic determinism and not politics. Meaning, why the science behind genetic determinism should be allowed instead of banned. Science merely unveils truths. Banning said truths is always bad.


https://openparliament.ca/bills/42-1/S-201/

This enactment prohibits any person from requiring an individual to undergo a genetic test or disclose the results of a genetic test as a condition of providing goods or services to, entering into or continuing a contract or agreement with, or offering specific conditions in a contract or agreement with, the individual.

Banning genetic tests is similar to these ideas

Ban academic tests - no one should be judged by their academic success

Ban criminal history - no one should be judged for their past criminal activity

etc

The idea that Genetic Tests are somehow not allowable or exactly similar is ludicrous. All anti-genetic determinism does is slow down and hold back society. If a genetic test can inform an employer on the success rate of their employee, it should be allowable. A full on genetic test ban is too heavy handed and stupid.

This is Pierre Louise Lions, 1994 Fields Medal recipient. His citation reads
>"... such nonlinear partial differential equation simply do not have smooth or even C1 solutions existing after short times. ... The only option is therefore to search for some kind of "weak" solution. This undertaking is in effect to figure out how to allow for certain kinds of "physically correct" singularities and how to forbid others. ... Lions and Crandall at last broke open the problem by focusing attention on viscosity solutions, which are defined in terms of certain inequalities holding wherever the graph of the solution is touched on one side or the other by a smooth test function."

Albino plants and animals are white because they have no pigment to reflect light with. If you gave a plant chlorophyll that didnt reflect light at all, chlorophyll that would itself be black because it doesnt reflect light, would the plant be its natural white color or take on the color of the chlorophyll?

This is fucking with my head because the answer to both colors being the dominant one is as far as i can tell the same.

Chlorophyll is green, it does reflect light.
Guess what, it reflects green light.
It's even in the name, chloro.
