# Isaac Newton What Did He Invent?
Isaac Newton published three books and invented the Newtonian reflecting telescope, a significant improvement on previous reflecting telescopes. Isaac Newton formulated the laws of universal gravitation and motion. He invented differential calculus at the same time as the German math... | |
# How does cooling scale with volume?
What equation would give me the answer to the question, "If i have a cup of water at a tempature of say boiling, how long would that cup of water take to cool off compared to say half that size of a cup of water." So the volume is in half. Its a general question I am just looking ... | |
# Is there a way to estimate or calculate the tidal range induced on a water-bearing planet?
Consider a system in which a central star is orbited by a planet with liquid water oceans, which is itself orbited by a moon.
Given the masses and distances between these three objects, is there some formula that outputs the ... | |
# Verifying Mathematical Expressions
This is a part of my calculator program. I have to check if the input entered by the user is a valid mathematical expression. The first check is performed by another program, where the program checks if the numbers and symbols are valid and it converts the string into tokens for fu... | |

Given an object, using the destructuring syntax you can extract just some values and put them into named variables:
const person = {
firstName: 'Tom',
lastName: 'Cruise',
actor: true,
}
const { firstName: name, age } = person //name: Tom, age: 54
name and age contain the desired values.
The syntax also works on ar... | |

# Seeking closed form for $\sum\sum\left\lfloor\frac{kr}{n-1} \right\rfloor$
I'm trying to get a closed form for $$f(n) = \sum_{k=0}^{n-1}\sum_{r=0}^{k-1}\left\lfloor\frac{kr}{n-1} \right\rfloor$$
It is fairly obvious that for large $n$ this grows like $\frac{n^2}{6}$ but for a step in a problem I am working I need t... | |

### Residence time in presence of moving defects and obstacles
We discuss the properties of the residence time in presence of moving defects or obstacles for a particle performing a one dimensional random walk. More precisely, for a particle conditioned to exit through the right endpoint, we measure the typical time n... |
