A coin flip by any other name (2023)

A Coin Flip by Any Other Name… Consider the following graph. If we remove each edge with independent probability 1 / 2 , 1/2, 1/2, what's the probability that there is still a path from the top to the bottom vertex? Since each subset of edges is equally likely to be removed, this is the same as asking how many ways there are to cut this graph in two—that is, how many sets of removed edges would disconnect the top and bottom vertices. In general, getting through a combinatorics problem like th

This new Gemini feature is the best and worst thing that’s happened for my learning

androidauthority.com Unknown 2025-09-21 17:00:00

Megan Ellis / Android Authority I’m typically a generative AI skeptic, but this doesn’t mean I’m not open to new AI tools that could be useful. After all, I found ways to use NotebookLM in my daily life even though I’m not a student. I even use Gemini’s Live mode to practice my second language. So when Guided Learning rolled out to the Gemini app, I wanted to test out whether it could turn my eagerness to learn new things into actual knowledge. The results were mixed, however.

If we remove each edge with independent probability 1 / 2 , 1/2, 1/2, what is the probability that there is still a path from the top to the bottom vertex? Since the removal of each subset of edges is equally likely, this kind of question is equivalent to counting the subsets of edges that we can remove without disconnecting two vertices.

On the morning of 20 January 1811, somewhere off the west coast of Africa, the crew aboard the Amelia ordered the ship’s captives onto the deck. Much like every other morning, they planned to impose a strict routine of exercise, meals, and then confinement back belowdecks. But that day, things would be different. As the captives clambered from their confines in the hull and into the morning sun, the crew looked on in horror: they were armed with wooden planks. By nightfall, the ship was under ne

Lawyers for Google and the Justice Department will return to a federal courthouse in Alexandria, VA for a roughly two-week trial about how to restore competition to the advertising technology markets that Google illegally monopolized.
