it would be nice if it were portable

Learn to program and make one yourself.

I recommend Haskell, the language for true mathophiles.

See >>>/g/ for more friendly and useful advice.

say f:N->R is a mapping from the natural numbers to the rational numbers in [0, 1]. does the infinite sum from 0 of f(n) converge?

i meant a bijection, not only a mapping

I would assume not, there is probably a conflicking rules proof you can make to prove it. Like why is 1^infinity undefined kind of thing

Chicken_Pie.jpg

Hello /sci/
I want to make a pie. For that I will be using a dish that is 36cm (14 inches) long, 25cm (10 inches) wide and 10cm (4 inches) high.

I want to cover the base, the sides and have a lid as well.
How much flour and fat will I need to have enough dough to achieve this, if I want the dough to be about 3-5mm (0.11-0.19) thick and I am using half flour to fat (so 600 grams of flour and 300 grams of butter)

Thanks for your answers.

Picture related; a pie.

Can entropy ever be reversed totally?
10 posts and 2 images submitted.
>>
Let there be light.

>>8716650
Constraints give entropy form, but no entropy means no adaptation.
In the case of living systems on earth, entropy needs to be ordered but not eliminated
*puts atmospheric carbon into the ground*
>>
>>8716650
It can't even be reversed partially in any amount at all. If something exists, there will be forward moving entropy, no exceptions.

Is the production of solar panels more environmentally polluting than oil/gas?

I'm not finding a compounded report on comparing the total effect of mining/processing crystalline silicon, amorphous silicon, cadmium tellurium, copper indium gallium diselenide, silver, tellurium and indium. Or the materials used for the batteries, lithium, etc.
But I'd bet if you could compile it all, it would dwarf oil/gas

Solar and Lithium Ion battery production also has a significant amount of waste but that can be disposed off safely unlike Oil/Gas which is released into the atmosphere.
