Almost literally. For those that don't know, Biff was based on Donald Trump:
How about some general calc tips. The whole subject revolves around understanding the concept of the limit and the difference quotient. Go to YouTube, Kahn academy, until that concept clicks.
Most of what you will do with derivatives are shortcuts to manually running things through the difference quotient and doing a ton of algebra and trig. Some stuff is easy to memorize, like differentiating and integrating trig ratios.
If you have a solid under of the above, integrals to derivatives are very similar to what division is to multiplication. I.e. undoing it (but not all the way, you'll understand why it is impossible when you get to it). The things you memorized for derivatives will be super helpful here.

Eh why not? A guy in charge of an oil company leading a climate conference? Makes sense. I was worried there might be a conflict of interest at that sort of thing.
I even question the usefulness at high levels. It doesn't measure how much wealth is produced. Say our GDP is 10 billion. Let's say 2 billion is tshirts that suck and get thrown away. Next year we make tshirts that last 5 years and our GDP is 11 billion because they cost more. Year 3, it shrinks to 9 billion because we don't have to make as many tshirts. We are better off in year 3 than year 1 by a billion, because we actually kept those shirts instead of tossing them.
I would like to see GDP numbers adjusted for useful production. E.g. since 40% of food is trashed, cut that portion of the GDP by 30% (we need some wiggle room so a bad crop doesn't cause a famine)
Almost everything you buy is produced using fossil fuels to extract the raw materials, transport the materials to a factory, power the factory, and transport it to you.
Buy less stuff. Buy stuff used, that is recyclable, or sellable/donatable.
Buy quality. E.g. pima cotton shirts, 50 year shingles or metal roofing instead of 25 year shingles, mid-high end compute devices. Quality costs a little more up front but will save $$$ and GHG in the long run. It also works better. I have found the biggest bang for buck is building materials. When I replaced my roof, 50 year shingles over 25 only increased a 5 figure project cost by 500 dollars and cut in half the cost of roof replacements over time. If 25 year roofs were eliminated, we probably cut the GHG from shingle production by some double digit percentage.
Does the bill specify the cost of the lease? What is stopping the federal government from making the lease so expensive that it isn't desirable or gives us enough cash to build HSR connecting every MTA with >500K population from Portland Maine to Miami
What about ramping up bamboo production? It grows super fast and is relatively useful.
Thank you. I'm not a fan of GDP. If you and I started crotch kicking businesses and paid each other $1,000,000 dollars to kick each other in the crotch, we just contributed $2,000,000 to the GDP with nothing of value created. My testicles hurt and your $PARTS hurt.
Lots of things are holding us back.
-
Too much risk starting a business. There is no guarantee you will get a job as good as you left if the business fails. You can lose the opportunity cost on investments so you can retire or cover a major expense. Health insurance is usually provided by jobs, so you risk access to medical care.
-
Health insurance is provided by employers. Changing job carries risk of getting insurance that will screw you over or have more out of pocket costs than any raise can make up for.
-
Housing costs are so high moving is risky. Buying a place to live at these levels could land you underwater if the market crashes.
-
Transportation almost requires a car, which are money pits even if you get a reliable car that is efficient and you DIY maintenance. You still need parts, insurance, registration, taxes, and fuel. Driving in the United States of Asphalt sucks because traffic jams are frequent in many areas. Since it is practically mandatory, you get to share the road with high people, irresponsible people, people driving cars that are unsafe to even look at, sleep deprived people, and people that for whatever reason can't drive well.
-
Child care. We get so little parental leave that isn't even paid leave and pay out the ass for early childhood care. If you have more than 2 small children, it is probably cheaper to hire a private nanny.
-
Shitty shit. Shitty toys. Shitty furniture. Shitty appliances. Shitty clothes. Shitty shingles. Shitty carpet. There is a lot of shitty shit out there that should never have been made that is long term more expensive than good shit. All that shitty shit filling our shitty houses that we drive home in shitty canyoneros took energy and materials provided by or extracted using fossil fuels. Then it was shipped using fossil fuels. Then when a fire/tornado/hurricane/whatever wrecks our shitty shit we have to pay a shitty insurance deductible and a higher shitty premium.
From the article:
"and a missing adapter for use at nearby chargers. The Tesla went dead as Liebau searched for a charging station,"
It sounds like they did try to charge it. It sounds like they couldn't use the nearby charging locations without the adapter.
I'm not German, but if I were to guess It's all about the cars. We need to stop driving cars en mass. Isn't the car industry a significant portion of your economy?
Do you have a case? You need to mount it in a case. Next you need to install an OS. For bare metal installs, you will typically use a thumb drive to install from.
I'm guessing you didn't use ESD protection. If you didn't there is no guarantee it will work or for how long:
