They’ve switched from using writing rooms, to having fully pitched and written pilots and seasons before an order comes out.
That’s why we have a lot more awesome first seasons, and complete crap second ones lately.

I can understand that, Satire is fairly new, having been invented in the early 90s by Professor James Satire who was inspired by the dance/funk ballad ‘Pump up the Jam!’ by Technotronic.

Not in comparison to… normal things like people and manufacturing.
And oil is oil, it’s self-powering. Many/most are powered off of the propane out-gassing to dedicated turbines.
- Comment on Know thy enemy 5 months ago:
Yeah, but Alaska uses dramatically less energy than… like, everywhere. Given that there are no people and the only industries are either oil or resources.
- Comment on Know thy enemy 5 months ago:
I’m not disagreeing, but if the energy is surplus, might as well make hydrogen, at least we don’t end up with pollution.
- Comment on Know thy enemy 5 months ago:
I mean, yeah, but also, that’s not really efficient or effective for burning.

We can make hydrogen, we can’t ‘make oil’.

So, if you’re an atlatl expert I see it.
But this is why we transitioned to crossbows from longbows, takes a lifetime of training to make a good longbowman.
Then again, not like they had anything better to do.

Yeah, I didn’t do the carbonic acid, then there’s the increased bicarb buffering around the pleura, couple other facts.
www.ncbi.nlm.nih.gov/books/NBK539815/
Upon entrance into red blood cells, carbon dioxide is quickly converted to carbonic acid by the enzyme carbonic anhydrase. Carbonic acid immediately dissociates into bicarbonate and hydrogen ions. As previously stated, an increase in hydrogen ions stabilize the hemoglobin in the T-state and induces oxygen unloading which leads to shifting of the dissociation curve to the right.[6]
Thus the acidity causes o2 release. Temperature (lungs tend to be very cold in the body) is important too.
Oxygen unloading is favored at higher temperatures which will cause a rightward shift. On the other hand, lower temperatures will cause a leftward shift in the dissociation curve. A notable example of this is exercise, where the temperature of muscle increases secondary to its utilization, thus shifting the curve to the right and allowing oxygen to be more easily unloaded from hemoglobin and deliver to tissues in need.
It’s amazing how subtly it works to gently increase efficiency where we need it. Otherwise it’s just a very weak oxygen bond (which is hard enough given oxygen is extremely non-polar and all you have are the valence pairs.
www.jbc.org/article/…/fulltext
Wow, I’m impressed, they’re using spin-coupling which is a pretty dicey effect.
Thus, we can conclude that the facile binding of O2 to hemo- and myoglobin arises primarily as an effect of the topology of the binding curves for the four relevant spin states. This topology, with nearly degenerat>e and parallel curves, is caused by the near degeneracy (within 10 kJ/mol) of the triplet and quintet states of deoxyheme. Therefore, the design by nature of iron porphines having close-lying spin states of a particular symmetry and energy is a means to tune binding of small ligands and overcome the activation barriers of these spin-forbidden reactions, despite the moderate SOC of first-row transition metals. The resulting barrier height makes up most of the rate enhancement due to the exponential dependence on the rate, whereas one or two orders of magnitude may come from the increase in the transmission coefficient.
That’s some fucking crazy ass engineering by nature, A weak, highly reversible bond with the molecule keyed to both pH and thermal triggers. That was a fun rabbit hole.
- Comment on Colours of Blood 5 months ago:

It’s sensitive to pH, so it absorbs oxygen more readily in the lungs, and releases it slightly more near tissues that need it, as they have co2 which slightly acidifies the blood in solution (h2co3).
-
It’s effective and well tuned for our biology, it doesn’t bond strongly, and is well suited for the air-blood interface, unlike others that often favor water-blood or water-the fluid worms use instead.

- Comment on Why are laptop adapters so much larger than phone adapters of same power rating? 5 months ago:
-
They don’t have to, I have Gan chargers that do a lot.
-
Less pressure on laptop manufactures to shrink as much.
-
Duty load: the big one.
You’re not just charging an hour at 20w and unplugging it, or tapering the charge, you could be using it at max rated output for days, that means much more stress, it needs to radiate more heat, and generally needs to be bigger.
As for fluctuating load, shouldn’t be as much of an issue, laptops often do their own power conditioning because the battery is fairly rough, and you’re going from 12-20v down to 5 and 3.3 then 1.6 and 1.3 to vcc for the chip, there’s plenty of filtering at each stage and they’re isolated by the smps controllers and input caps.
But pulling constant rated duty cycle basically doubles the size of power supplies normally, GaN technology helps a lot (which is why those little power bricks can do 100w+ now even though they got a lot more dense).
