Widely accepted estimate for the 1917 Halifax Explosion is ~2.9 kilotons of TNT.
Minor Scale (1985, New Mexico) — the largest non-nuclear manmade explosion ever.
It used 4,744 tons of ammonium nitrate/fuel oil, equivalent to ~3.2 kilotons of TNT. It was a deliberate U.S. Defense Nuclear Agency test to simulate nuclear blast effects.
In a May 18 procurement filing, NASA announced its intent to add six post-certification missions, or PCMs, to SpaceX’s commercial crew contract on a sole-source basis. The agency would order up to three of those missions at the time it added them, formally starting preparations for them.
... Adding six missions to the contract would cover three years of ISS operations, at a rate of one mission every six months. With the currently contracted missions, running through Crew-14, flying through the fall of 2027, the extension would provide coverage through late 2030, when the ISS is slated for retirement. NASA has previously stated the last crewed mission would likely spend a year at the station.
Though it is not stated yet exactly how much SpaceX will earn with these additional missions, based on previous contracts the revenue will likely range from $1 to $2 billion. Overall, SpaceX has probably received somewhere between $4 to $6 billion additional earnings that was supposed to go to Boeing.
Instead, Boeing is now out of the picture entirely, though NASA is being very coy about saying so.
Exactly. The top 2% will not take PEDs because it would disqualify them from the clean Olympics, which means no records will get broken.
Pavements are racetracks. Public space no longer feels safe.
Named for their ultra-thick tyres, fatbikes are capable of hitting speeds up to 60km/h. Sharing space on Amsterdam’s famously crowded cycle paths, they have increasingly become a source of friction with traditional cyclists who view the heavy, fast vehicles as a menace.
Last year saw a rise in public concern about the number of asylum seekers in the Netherlands who appear to be using these typically expensive items as their main mode of transportation.

"All told, a remarkable two-thirds of the Valley’s nearly 400,000 tech jobs are now held by those born abroad, according to a 2025 report from the think tank Joint Venture Silicon Valley."
Yep. Make us all goldfish in an aquarium.
Nevada, Maryland, and Ohio federal district courts sided with states.
Nevada: Dissolved Kalshi injunction; ruled sports contracts resemble gambling, not CFTC swaps.
Maryland: Denied preemption; state gambling laws apply.
Ohio: Denied injunction; similar reasoning.
New Jersey and Tennessee courts have favored Kalshi/CFTC.

Citadel CEO. I have seen work that would normally be done by people with a masters or PhD in finance over the course of weeks or months, being done by AI in hours or days.
