# A trivially copyable ticket for a unique_ptr
In Chandler Carruth’s CppCon 2019 talk “There Are No Zero-Cost Abstractions,” he talked a lot (not exclusively, but a lot) about the hidden performance cost of std::unique_ptr. See, unique_ptr may be the same size as a native pointer, but because it has a user-defined des... | {} |

• Unit 5: The Integral
While previous units dealt with differential calculus, this unit starts the study of integral calculus. As you may recall, differential calculus began with developing the intuition behind the notion of a tangent line.

# Is the metric ${d(x,y)}\over {1+d(x,y)}$ complete where $d$ is the usual Euclidean metric on $\mathbb R^{2}$
Let $d(x,y)$ be the usual Euclidean metric on $\mathbb R^{2}.$ $\mathbb R^{2}$ is complete under $d(x,y)$. I have this subspace given $$[0,1]\times [0,\infty )\ \ of\ \ \mathbb R^{2}.$$ I thought this is also... | {} |

# 2.3. Create gridded sections¶
Once the section longitude and latitude endpoints have been defined, and the param.py file has been properly set, the next step is to process the model grid. This is achieved in three steps:

# Calculating proper time using schwartzchild metric
1. Mar 3, 2012
### demonelite123
I am using the schwartzchild metric given as $ds^2 = (1 - \frac{2M}{r})dt^2 - (1 - \frac{2M}{r})^{-1} dr^2$, where I assume the angular coordinates are constant for simplicity.
So if a beam of light travels from radius r0 to small... | {} |

All Peano axioms except the induction axiom are statements in first-order logic. The induction axiom is written as $$\forall X(0 \in X \land \forall n(n \in \mathbb{N} \rightarrow (n \in X \land n' \in X)) \rightarrow \mathbb{N} \subseteq X$$, where $$n'$$ i... | {} |
# Constant acceleration of velocity

### TickleMeElma
A falling stone takes 0.28s to travel past a window 2.2m tall. From what height above the top of the window did the stone fall?
So we have time and dinstance, but not the acceleration, which confuses me terribly. Do I need to find velocity? Or do ... | {} |
# When can we write the square of a matrix as the product of the matrix and its transpose?
I often see something like $(A - B)^2$ being written as $(A - B)(A - B)^T$ . Here $A$ and $B$ are two matrices. I can see that this is possible when $A$ and $B$ are scalars (i.e) single element matrices. In what other cases does... | {} |
