I understand your sentiment, but the public absolutely pays for cars. Road construction and repair subsidies car ownership and is paid for by the government.
If you didn't include the cost of the tracks in a light rail public transportation proposal you bet your ass there would be more built!
Stumbles his way into being a background character; an annoyance to the main actors and the plot. Then turns out to be the puppet master all along. I love this fan theory mostly because it is the only way to make Jar Jar a retroactively tolerable character.
This is the exact path I took, and I highly recommend it. Code academy python then immediately wrote some code to scrape some websites and email me if something I wanted to buy dropped to a price I'd be willing to spend.
I'd say all in all it took 3 weeks to a month, but I've been able to not code for months at a time and still feel comfortable when I come back.
I am NOT a programmer, I am someone who can cobble something together to accomplish a specific task. I never got to the more abstract concepts you listed, but maybe one day!
I love these videos so much and cannot recommend them enough. No narrative, no music, no ads, just well placed camera shots to make the whole thing self explanatitory. I feel like I have learned so much from him and I have never heard his voice.
Ok stupid question time. The temperature during the Cretaceous was on average hotter than the 3.9C increase stated to halt photosynthesis. There was certainly photosynthesis going on then, how is that possible? Do we assume the plants had enough time to adapt to that new temperature, changing their photosynthetic machinery to work at higher temperatures than today?
Russian assassination are pretty clear. Anyone with half a brain can put the pieces together, but there is just enough plausible deniability that there cannot be direct retaliation legally or politically. It is a clear threat but just barely veiled enough to avoid legitimate retaliatory action via legal or international responses.
What about a fertilized but unhatched duck egg? That's kinda both a duck and not a duck.
I think you'd consider a roast duck a duck, but what about a duck drumstick? Would you say that's not a duck? If so, how much of the roast duck needs to be connected for it to be a duck?
I agree that planting trees is generally good, but doing so can't sequester the amount of carbon released by humans since the start of the industrial revolution. We need other avenues to do that. If we returned forests back to how they were 100,000 years ago (untouched by modern humans) the new trees that would grow wouldn't be able to soak up the CO2 released. Returning the forests to that state with the current world population isn't feasible either as we need some of that land for agriculture.
I get your sentiment, but we're beyond a 'plant trees' solution.
This is such a stupid headline. It gives no context for that number. Is that big or small compared to other years? Is it big compared to other countries's military contractors? What does 'made' mean? Is this revenue or profit?
It's obviously intended to make us outraged because it's a big number, but the article actually said it went down by 3% last year. Why wasn't that the headline?
You certainly would see longer ranges for the same battery if you just swapped the cabling and motor over to superconducting versions, but there are kind of two scenarios at play here.
You have highway driving where a lot of your losses are mechanical due to high sustained speeds (air resistance and friction). Those wouldn't go away, but your "electrical to mechanical" losses would be reduced, so you'd see modest improvements.
Then you have around town driving where your losses from accelerating and decelerating are much larger than the mechanical losses (air resistance and friction). Here with proper design changes I think you would see spectacular improvements in efficiency.
Unfortunately, this doesn't help much with the EV 'range anxiety' issue haha. Go figure.
There are two major mechanisms at work with a solar panel circuit. The production of "free electrons" and then the flow of the "free electrons". Solar panels are basically special crystals that make the "free electrons" when they're hit with sunlight. Once the 'free electrons' are produced, they flow through conductors to do whatever electrical work we want them to do.
The that special crystal is what is inefficient and it can't be replaced with superconductors. Only the flow portion of this circuit could be replaced with superconductors.
I hope this helped, it's a pretty simplified explanation.
Semiconductors are used for transistors because they give us the ability to electrically control whether they conduct or resist electrical current. I don't know what mechanism you'd use to do that with superconductors. I agree you don't 'have' to have resistance in order to achieve this functionality, but at this time semiconductors or mechanical relays are the only ways we have to do that. My focus is not in semiconductor / IC design either so I may by way off base, but I don't know of a mechanism that would allow superconductors to function as transistors (or "electrically controlled electrical connections"), but I really hope I'm wrong!
