I make short, to-the-point online math tutorials. I struggled with math growing up and have been able to use those experiences to help students improve in math through practical applications and tips.

Fullerenes are hollow carbon molecules where each atom is connected to exactly three other atoms, arranged in pentagonal and hexagonal rings. Mathematically, they can be combinatorially modeled as ...

An audiogram can diagnose your hearing loss and indicate what type of hearing loss you have. It can distinguish your hearing in each ear and whether you have hearing loss on one or both sides. You can ...

A new technical paper titled “Fabrication of graphene field effect transistors on complex non-planar surfaces” was published by researchers at Imperial College London. “Graphene field effect ...

Abstract: A new method is proposed to synthesize arbitrary-tiled arrays fitting multiple, generally conflicting, requirements for multiantenna systems operating beyond 100 GHz. The array structure is ...

We may never know why it occurred to Donald Trump or someone with access to his Truth Social account to post a graph about immigration at 2:20 a.m. Fox News was re-airing Sean Hannity’s show during ...
