Yeah there’s a reason I’m leaving the energy sector. The choice to use fossil fuels for grid in the last 50yrs has been and will continue to be a purely political one.

PC: We’ll used nicer language to express our bigotry.
Woke: I realize some of my inherited ideology is bigoted, doesn’t represent my values, and I’m fixing it.
- Comment on the Home Alone house then and now 2 weeks ago:
I get your point but they’re both reflections of how the wealthy decorate in the different eras. The 80/90’s house would likely have been advertised with the same wallpapers and dressed up similar to the movie set by Realtors because that was the style.

Solidly A2 (European system) with that grammar(English translation) so 3-6 months (1-2 terms of university course).
- Comment on the Home Alone house then and now 3 weeks ago:
The before pictures are bourgie and give a 90’s generational wealth ick, but at least it still looks like there’s a human being living there experiencing something nearly recognizable as a human emotion from time to time.

But reference frame changes as the cube passes through the portal. The piston would feel resistance as its momentum is transferred to the cube to conserve it.

Turns out they’re the reason we haven’t had nuclear war. All this nonsense about MAD, HAHAHA no! The powerful just won’t do it without baikouts for their investments.

The nuclear war clause is in nearly every insurance policy, not just pets.

- Comment on Since Endorphins and Serotonin are two completely different chemicals which give the biggest "High"? And does the release of some of one of them overcompensate for the other? How come? 1 month ago:
Different systems. So probably synergistic effect but I’m not an expert.

- Comment on Why do tires have the width and diameter they do? 1 month ago:
Responding to:
More rubber on the road means more grip. As the weight and corner speeds increase, you need more of it.
However,
a larger area makes it so small patches of lower friction (sand patch or water or trash or whatever) have less of an impact, with more area you have a higher chance to still be in contact with the asphalt.
Unless we’re talking about liters of sand/gravel then this fails to explain how motorcycles have as much grip as cars do, as is evidenced by cornering ability.
More area also gives more opportunity for the ridges in tires to displace water or grip onto gravel/dirt.
Tread depth and pattern handle these.
…
Racing tires are wider because they need to handle higher loads. Racing slicks also maximize contact area to extend tire life and reduce wall thickness. There’s thermal conduction as well. Rubber is an insulator. Rubber friction changes with temperature. So does modulus, leading to more deformation and thus more heating. Too thick rubber makes a hot tire that loses friction coefficient. Too thin and it wears too fast, you’re on steel 3 laps in. so you make it wide enough to distribute the load, reduce stress, and control heating while trading off mass. This is also controlled by chemical composition. After that you’re designing for weather conditions.
Passenger vehicle tires focus more on climate and adverse road conditions and long life. Because they are much lower performance, they have much lower loads and use tires with less contact area. The same is the case for motorcycles and bicycles.
- Comment on Why do tires have the width and diameter they do? 1 month ago:
There is no pressure nor area in the friction equation. ‘Fu=u*Fn’
Fu - friction force
u - friction coefficient
Fn - normal force
Pencil thin tires of the same material have the same grip as extra wide ones in dry conditions. Tread geometry can change for wet but only to prevent hydroplaning, friction is still the same between the tires fire a given condition.
More contact area means less stress on the rubber which means the rubber wears less for the same load. A car weighs 2 tons, a bike+rider is less than 100kg/200lb. 1/20 the contact area for similar wear. If a car had bike tires they would probably melt after a few km

- Comment on Can energy be associated with/related to spacetime ? 2 months ago:
e=mc^2
So
c=√(e/m)
Or actually do calculus but screw that let’s just speculate that a photon having a lessr infinite energy is equivalent to a lower speed of light. Therefore space has shrunk or time has expanded or the opposite or whatever.
