Wanneer leren onze politici dat je het halen van harde doelen niet in wetgeving moet plaatsen? Dit kun je alleen doen wanneer je a) hard grip hebt op het behalen van doelen en b) dat je weet wat het gaat kosten om dit te halen (en dat dit betaalbaar is in relatie tot andere

Never before has an hour of Presidential rhetoric cost so many people so much. Markets continue to move after my previous tweet. The best estimate of the loss from tariff policy is now is closer to $30 trillion or $300,000 per family of four.

Niet terugslaan is het verstandigst als de Amerikanen tarieven afkondigen/verhogen. Schieten we onszelf mee in de voet, zoals Sandra Phlippen uitlegt.⬇️

Wat merken wij als de wereldhandel terugvalt? “Het kan heel pijnlijk worden,” vertelt hoofdeconoom ABN-AMRO Sandra Phlippen: “Als wij terugslaan met tarieven en Amerikaanse producten duurder maken, dan gaat dit over de rug van de Europese burger.” #Buitenhof

Puzzle: On a 1-way road with 2 lanes, blue and red cars are driving. The left lane contains only blue cars, the right lane only red. At a point, the cars have to merge to one lane. In doing so, the blue cars are bolder than the red ones, sometimes causing several blue cars 1/2

How do you handle outliers caused by heavy tails in an optimal way when you want to estimate (but not overestimate) the mean of a nonnegative random variable? With Bart van Parys, we answer this question in our preprint https://t.co/2nluxnnCDi

We consider the problem of constructing a least conservative estimator of the expected value $μ$ of a non-negative heavy-tailed random variable. We require that the probability of overestimating...

Does anyone know whether there an open-source implementation of the holomorphic embedding method to solve the AC power flow equations? Preferably the version where you can provide a nontrivial starting value.

How far would you go to finally get a reaction from an editor after inquiring multiple times about a paper status (submitted 12 months ago). Disclaimer: as editor, I messed up several times; this is not to complain. Am mainly curious. My postdoc advisor has (phone)called editors

Have been watching T&F since '84. As a 10-year old I could not understand how Carl Lewis jumped further than our living room. Most of the time the Dutch never won anything. But today interviews had to be kept short because there were so many gold medalists to talk to. Amazing.

Waarom deze voorzichtige formulering? Door het stoppen van wapenleveranties en het onthouden van inlichtingen hebben de Russen nu vrij spel. Russische raketten kunnen nu ongehinderd civiele objecten bestoken. Mogelijk gemaakt door Trump. Dit heet verraad. Niets anders.

Terwijl de Amerikaanse wapenleveranties en inlichtingenondersteuning stilvallen, voert Rusland massale luchtaanvallen uit op Oekraïne. Kunnen de raketten nog wel goed worden afgeslagen?
