The general form would be implicit differentiation! d/dx dx/dy e^x = e^x dx/dy

Fighting fire with fire sets the whole neighborhood ablaze, sure, but this isn't fire with fire. The current administration cut support and sent Marines in to patrol US streets. Newsome should punish those who cooperate with federally sanctioned hostile forces (don't kid yourself, as a marine I can tell you we are only deployed against hostiles) but this measure doesn't even explicitly punish. He's just not supporting the supporters.
People, stop ruining music! Tell your kids you've never heard of AC/DC but they have got to hear this band called Nickelback. If they respond "you don't know good music" then your job is done and they think AC/DC is amazing.
Not Costco tho!
Ach wheel
Just an explanation for anyone else, Biden started his term with a higher rate of deaths (steeper slope) and finished with a lower right (shallower slope) thanks for showing the removed graph!
Totally read that in Abe Simpsons voice
It's more complicated. Silicon has an overwhelming advantage on manufacturing because of IC, ultimately that will make the dollar per watt hard to beat. That's why Alta focused on applications with limited area.
I mentioned halides earlier (also called perovskite unfortunately). If you look at the NREL chart https://www.nrel.gov/pv/cell-efficiency the bottom right showed halides rapidly increasing in efficiency and the manufacturing has the potential to scale a lot. I remember a conference presentation a few years back showing efforts to repurpose newspaper printing machinery and just roll out cells at high volume.
My secret little inside tin foil hat voice says China might not be comfortable with an American supremacy in tech that can make relatively inexpensive drones that stay in the air indefinitely.
The earth is just a big rock
Silicon is hardly the best path forward but we have seen evidence of international sabotage of progress
Alta had custom implementation of 3-5 growth in order to produce high efficiency solar cells at a price competitive for ships, drones, etc. But once the tech for GaAs becomes competitive with silicon then the industry shifts, that's not a welcomed change.
Just an opinion.

All models are wrong, some models are useful. A model that is 100% correct is just reality. Science and physics boils down to observation followed by explanation which comes in the form of modeling.
New physics started when plank discovered quantization while integration raleigh-jean and weins laws for blackbody radiation. Schrodinger proposed a model among several proposed models and his fit the best.
Anyone who is surprised by science not knowing all the answers had fundamentally misunderstood science.
Finally, five fields: electromagnetic, gravity, strong, weak, and higgs. Magnetism is just an effect of leptons interacting with the electric field. That's the model, one day when we can explain more with another model there will be more questions.
Bonus points for anyone who knows the quote "who ordered that?"
