How could that possibly happen? Do you left-foot-brake?

or when all other forms have been neglected

Oddly enough that also makes individual transportation by car crap again lol. Cities that have ditched all other forms of transportation are some of the most congested.

No, which Apple would have to integrate into iMessage.

Until all phones use the same protocols in their stock messages app

Literally the point. Everyone is waiting for Apple, EU is considering forcing them (again.)

It goes further than that. Young's modulus does indeed determine the elasticity (springiness) of a material but don't go ahead and think it's only relevant for systems with moving parts that deform and go back into their original shape. Young's modulus is literally at the very heart of every structural engineering calculation, static or dynamic.

The stiffness of any structure is determined (among others) by E*I, I being the second moment of area determined by the shape of an object and E being Young's modulus of the material. The tension in any structure is also determined (among others) by (load)/E*I. So Young's is proportionally responsible for an objects ability to resist deformation under force and inversely proportional for the stress inflicted to the material by those forces. Both deflection and stress are potential causes for failure. If your structure loses a significant amount of its structural rigidity, it might fail. If the stress in parts of your structure rises significantly, they might fail.

So steel may only melt at 1400C, but it has already lost half its load bearing capabilities at around 550C. Whether a structure collapses entirely is mostly a question of what factor of safety the engineers have applied when dimensioning the components. If the temperature was 550C (hypothetical, for this example) and the steel beams did indeed lose half of their ability to resist deformation by the loads they were bearing, and the tension in them did double, even a relatively high factor of safety of 2 ( i.e. everything is built twice as strong as it needs to be) would be the tipping point for catastrophic failure. In reality the factor of safety was probably lower, between 1.5 and 2.

Okay, I suppose you wouldn't do that when replacing and old furnace but rather go for a hybrid system. In Europe loads of people are reacting to hiked gas prices and have perfectly fine furnaces in place that they don't want to get rid of.

You'd usually run two or more units in a cascade/multiplex when requiring large amounts of power rather than having one giant unit. Means you can turn off one or more units entirely for low heating demand.

In Germany this will likely still be a controversial take in 2026. Our political right managed to shift this debate into ideology territory and a good chunk of people believe heat pumps are environmentalists' fever dreams that don't really work in cold Germany.

A split system AC is a heat pump in any context. So is a refrigerator. They're all the same technology that move energy via a refrigerant's latent heat by compressing it into a warm part and letting it expand into a cold part.

Ich steck da nicht so drin, deswegen mal die Frage: das ist doch ausschließlich bei Corona Impfstoffen so, oder, gab es das schon jemals in der Geschichte von Arzneimitteln, dass Leute großflächig bestimmte Hersteller ablehnen und die Impfbereitschaft droht zu sinken wenn nur der bezuschusst wird? Das ist doch am Ende nur wieder dünn verschleiertes mRNA Geschwurbel, oder?

Wie kann ich mir das vorstellen, der Zug ist doch bestimmt nicht 8 Kilometer lang entgleist? Gibt es irgendwo eine Dokumentation des Unfallhergangs?

edit: hab's gefunden, wer Suchmaschinen benutzt ist klar im Vorteil. Und die Antwort ist: doch, ist er!

Klingt gefährlich wenn die Fahrzeuge durch die Gegend geschleudert werden wo andere laufen könnten, ich schlage einen 2 Meter breiten Metallschredder vorne an jeder Tram vor!

Joke's on them I don't tap I swipe
