Yes, I didn’t thing too much about food/calories in the past, so when I read about the connection it is in hindsight obvious, but I didn’t get the idea by myself.

Thanks a lot! Great write up, and the energy-stored view of calories makes a lot of sense and is very intuitive!

Thank you for your answer!

Thanks a lot! To the point and on an abstraction level that is very clear!

I care how much taxes I pay for several reasons (Germany):

• Rich people are taxed less than working people
• Given that we have one of the highest tax rates in the world, a big part of my taxes go into corruption, incompetence or the pensions of civil servants (pensions for civil servants are way higher than for normal people, especially for some pencil pushing)
• It gets even more fun, when I think about how many big companies are getting subsidized by my taxes with billions (speaking about companies which are making billions for their stake holders)
• In our system, costs for health care system and workers pensions are also mandatory deducted from my income (they don’t call it tax)… Given, what an average worker pays, we get not enough out of it, neither from health care nor when thinking about the pensions
• A final tax, which is not called tax, is for public TV/state propaganda. There were more scandals about that money recently than anything else: The higher ups in that system earn more money than the president of Germany (no kidding), people get special pensions for the rest of their life which are obscenely high (after working like a few months, again, no kidding)

Don’t get me wrong: I would happily pay taxes if the biggest parts would go towards services, infrastructure, public transport, health care, people in need and smart/strategic investments of the economy.

As it is right now, my taxes are siphoned into the pockets of the so called elite instead , so I care.

If you don’t care about paying taxes, you are either mostly happy about were the money goes or have too much money to care.

Wanted (2008) - The comics are brilliant, sharp, funny and intelligent. By leaving out everything smart/interesting from the comics they managed to create a mediocre action movie.

Thank you, sir! :-)

• Teaching math is mostly done w/o context and history, IMHO a lot of math makes much more sense when the original problem is understood, before the level of abstraction is being raised.
• Math is a also a language and a notation. Unless one uses math regularly, there is simply not enough practice/repetition to read/speak this notation.
• Math is a tower of abstractions, depending on other abstractions. A lot of topics in math depends on people understanding a lot of basic parts, which means if a student just got by with a prior topic, it is near impossible to catch up/understand what is currently being taught. (Compare to other topics: For example, if a student is bad in their Greek history, they get a fresh start when the topic is industrialization in England w/o any penalty.)
• Math in the primary and secondary schools is mostly computation, ‘real math’ is only taught to people studying MINT.

tl;dr

• we need a better curriculum in the primary/secondary schools
• we need more exercises in reading/writing the mathematical notation (sorry, just understanding math is not enough, because understanding doesn’t make one fluent)
• at least in my school years, math was not repeated enough.
• reading/understanding math is really hard, at the higher levels, understanding 2-3 pages on a textbook per day is an acceptable pace. I guess all the entertainment nowadays makes it not easier to sit still in a room and get math into ones brain

For me the ‘breakthrough’ with math was, simply to accept that at the higher levels we are speaking about symbols (abstractions) that follow certain rules and everything else is derived by pure logic. Just accepting that one is manipulating symbols with rules to get to other symbols and learning the rules, made it click for me. Disclaimer: Was lucky with great math teachers in university, but even in my university there were people who simply could not accept the game of mathematics and were frustrated, because they wanted easy question/answer style formulas in the sense: When you see this, substitute PI with 3.14 and multiply r by r and write down the number that your calculator shows. They never made any effort to understand where PI comes from, where the radius comes from and why it makes sense.

What is insane, is how many people studied computer science but are totally unable to apply mathematics to the problems they try to solve. Supposedly most of them learned relational algebra and discrete mathematics during their studies (and formal languages/complexity theory)… it is like something is missing in their ability to transfer what they learned in the university to basically the same problems where the symbols have different names. That is something I would love to understand.

there is no android phone that I am passionate about,

Not what you asked for:

A phone is a tool which should enable you to do stuff. Be passionate about friends, hobbies, art, not a piece of plastic.

Being forced to use iOS (work phone) and Android (Samsung, also work), both suck IMHO but Android sucks less.

My next Android will be a Pixel, as others suggested custom roms are the way to go, but even vanilla Android is more functional/open/practical for my needs than iOS.

I would never buy Apples shit with my own money: Dumped down, locked down and in the end you are renting a device from Apple to pay fees for their Appstore and Cloud offerings and vendor lock in. No thanks.
