A photo of the front cover of issue 1655 of Private Eye magazine. The main headline reads "STARMER: UK WILL RECOGNISE PALESTINE." Below this is a photo showing a devastated urban landscape of destroyed buildings, over which a speech bubble from Benjamin Netanyahu in the foreground says, "No one will recognise Palestine after I've finished with it."

The title graphic from the musical Hamilton. Instead of a silhouette of Alexander Hamilton forming the tip of the large black star at the center of the image, there is a black and white image of a balding, sideburned William Hamilton.

William Rowan Hamilton was born #OTD in 1805.

His reformulation of classical Newtonian mechanics via the principle of stationary action is one of the most beautiful ideas in all of physics, and is at the heart of nearly every modern theory in physics. 🧪 ⚛️

Draft from me: The European mind cannot comprehend a $100 copay before service is rendered that doesn't count towards your deductible just for an out of network doctor to deny your prescription because the insurance company removed prior authorization for the medication you've been taking for half your life because it's a preexisting condition.

Total load of reactionary nonsense. Especially at sea wind turbines deliver clean electricity, with no noise, no emissions, no CO2-pollution, no dependence on totalitarian petro-states, no risk of environmental calamities and no risk of nuclear proliferation.
As such wind turbines are beautiful.

The White House post on X was captioned: "When ICE books you a one-way Jet2 holiday to deportation. Nothing beats it!" It has been met by some with criticism - one user said the clip was "embarrassing and unprofessional", while another said that it "shows a real lack of humanity". Others have praised Trump for his stance on immigration.

BBC News is really unequipped to deal with fascism

This past week, the 79-year-old president announced he’s ended six wars (some that have been going on for centuries), asserted that windmills drive whales insane, called for Beyoncé to be prosecuted, claimed Obama committed treason and complained a convicted pedophile “stole” teenage girls from him.

The “deal” that Brown made with the Trump admin is much more extreme than is being reported. It includes government oversight of course evaluations and no barrier to government interference in faculty hiring.
