Good–Turing frequency estimation is a statistical technique for estimating the probability of encountering an object of a hitherto unseen species, given a set of past observations of objects from different species. (In drawing balls from an urn, the 'objects' would be balls and the '... | {} |

# Pole-Zero Plots Diagram Explanation
I experiment with the coefficient quantization in an IIR filter. I change some values like the passband ripple and also how many bits i want for the quantization method. In the first picture i have 1db passband ripple , 'round'and 7-bits as the quantization method:

Infinite loop spaces
Let $X, Y$ be infinite loop spaces: $X = QA$ and $Y = QB$, where $A,B$ are connected topological spaces, and $Q$ stands for $\Omega^\infty S^\infty.$ Let $f:X \to Y$ be a continuous map such that $\Omega f: \Omega X \to \Omega Y$ has a left inverse, i.e. there is a map $g: \Omega Y \to \Omega X$ s... | {} |

# Introduction
While gene expression profiling is commonly used to gain an overview of cellular processes, the identification of upstream processes that drive expression changes remains a challenge. To address this issue, we introduce CARNIVAL (Liu, Trairatphisan, Gjerga et al 2019), a causal network contextualization... | {} |

# Tensor product of two vector spaces (finite dimension)
I'm studying the tensor product from wikipedia.
If $V$ has a basis $e_1,\dots,e_m$ and $W$ has a basis $f_1,\dots,f_n$, then the tensor product $V\otimes W$ can be taken to be a vector space spanned by a basis consisting of all pair-wise products of elements fr... | {} |

### Smooth23
Okay, the biggest problem I'm still having 12 weeks into physics 2 is that I cannot for the life of me see how the direction of r-hat is determined. Can anyone explain it to me? Specifically in regards to Biot-Savart law, etc.
