Hey! 😊 I want to write a function in Python that returns the multiplication table $20\times 20$. We do that using lists in lists, right? I have written the following : def mul_table() : Prod = [] Table = [] for i in range(21) : for j in range(21) ...

I am new to the field of climate change. Are there publicly available simulation code for Earth's temperature history, going back, say 2000 years, with a resolution on the order of years? Thank you very much.

Hello, I have a few questions and I'd appreciate if you can please help me. 1. If I want to say "for every ## i \in \Bbb N ## and ## 0 \leq j \leq i ## define ## A_{i,j} := i ## and ## B_{i,j} := i \cdot j ## ", then is the logical formula used for this is as such?: ## \forall i \in \Bbb N...

The K-L condition has projection operators onto the codespace for the error correction code, as I understand it. My confusion I think comes primarily from what exactly these projections are? As in, how would one find these projections for say, the Shor 9-qubit code?

Hello everyone. I have been recently working in an optimization model in the presence of uncertainty. I have read https://www.researchgate.net/publication/310742108_Efficient_Simulation_of_Stationary_Multivariate_Gaussian_Random_Fields_with_Given_Cross-Covariance in which, a methodology for...

What would be the best way to cover the 3 digit code at the back of a credit card? Some suggest using correcting liquid (but it is easy to remove it and apply new one). Many restaurants still get our cards to swipe at their counter. Only very few go to table to swipe it. Also sometimes we gave...
