Claiming to be neutral and even-handed, President Xi Jinping supports a ceasefire. Yet he refuses to condemn Hamas for its 7 October atrocities and criticises Israel. He knows a ceasefire would benefit Hamas – but also that it’s a crowdpleaser in the countries of the global south. What really in...

Does the following hold?: $$ \sum_{a, b \in \mathbb{N}^+, \ \gcd(a,b) = 1} \frac{1}{ab(a+b)} \ = \ 2 $$ Numerical computations suggest this may hold, but on the other hand it would be quite surprising if that sum is indeed an integer. If it indeed holds: is this a known identity?

Consider a sprinkle working in a no-friction universe (no air drag, no friction in the bearing). If this sprinkle ejects water with a constant flow rate, shouldn’t it be accelerating forever?

I am using Mapzen global terrain to create a topographic map. How can I get a very simplified result like on the map of Greece? Should I use contours lines ? And how to smooth them ? (wich algorithm to use ?). What I have: What I want : What I tried : Scale reduction in symbology (but i am sti...

I would as a teacher I would like to add to my pdf (usually it is an article) a sequence of images for some geometry proofs. For example, it would be nice to have something like: Draw the triangle ABC Draw the bisector of A Draw the height of AB passing through C ... For each step, I would like...

what if a miner just broadcast the header and never broadcast the body .For example: A miner after succesfully mined some block , he just broadcast the header for all other miners and hide the body or never give the information of the body. Under this situation what will happen ? All other miners...

I'm looking for any information on how to replace or repair this potentiometer. It's an AB R450 J-type potentiometer on a Brent ceramic wheel from the early 70's, I believe. I cannot find anything online that matches it. The problem being it is stuck at high speed only with only a slight variatio...

Let $F$ be the set of all continuous functions $f : [1, 3] \to [-1, 1]$ such that $\int_{1}^{3} f(x) = 0.$ Then, find $$ \sup \int_{1}^{3} \frac{f(x)}{x} dx,$$ where $f \in F$. Now, my first thought was to try Cauchy - Schwarz inequality, but it can only be applied when all terms are positive, bu...

Prove that: $$\lim_{x\to 0}\frac{A^x-B^x}{x}=\ln\frac{A}{B}$$ Without using L'Hôpital Rule or the classic definition of the derivative. I find that $$\lim_{x\to 0}\frac{(e^x)^{\ln{A}}-(e^x)^{\ln{B}}}{x}$$ but no other ideas

I have an invention in mind, but there is a certain patent with claims that look nearly identical except for one minor part, where the existing patent differs. This minor part is in the very first claim itself. Yet, the existing patent and my invention differ wildly in outcome if this minor part ...

I am trying some samples. They make a frame around the text. I know there are already realized commands for it but I want to practice leaders, rules and boxes in LaTeX. So the examples below are kind of artificial. \documentclass[a4paper,12pt]{article} \usepackage[utf8]{inputenc} \begin{document...
