"Counterexamples in Analysis" by Gelbaum and Olmsted.
You will find that many of your intuitions you picked up in calculus are violated in analysis. For instance, in calculus, many examples are both continuous and differentiable everywhere. But is every continuous function also differentiable? Nope! See the Weierstrass function [0].
The book is full of such counterexamples that will help you understand analysis at a deeper level (and avoid many pitfalls)
Imagine what an app could do if they had access to your entire message history! (Why would anyone give apps access to their messages? So that they can send / receive special emoji, for example.)
$300m buys a lot of good will, and maybe some favirbale coverage.
And although companies would be able to deduct salary expense to reduce their own tax bill, they still benefit from the tipping scheme. If the worker receives, say, $10 in tips, the company would have to pay them $15-$20 to give them the same after-tax income, since a large portion of the wages would go towards income tax and social security. So, if the worker makes the same take-home pay through tipping rather than wages, the company and the customer both pay less! The real cost is borne by the taxpayer, who has to pay higher taxes elsewhere to make up for the loss.

When blue apron first started, you couldn't even cancel it through the web interface -- You had to send an email to request cancellation.
edit:
Blue Apron still uses these slimy tactics. I created a screenshot [0] of the Blue Apron cancellation page [1] (in case they change it.) Look at how difficult they make cancellation! The question is literally, "How do I cancel my account?" and the answer should be a simple button to cancel. Instead, the first paragraph tells you not to cancel, just delay, and then the third and fourth paragraphs are just additional needless text.
Then, when you email them to cancel, they don't actually cancel your account -- they send you a link to the cancellation page. Why do they require you to email them to get the link? Why don't they just put it on the FAQ page? The answer is that they're using slimy tactics to increase friction and demotivate you from cancelling.

Uh, Einstein published four papers that revolutionized four areas of physics in one year:
* The photoelectric effect
* Brownian Motion
* Special Relativity
* Mass-Energy Equivalence
Sure, he didn't do it alone. But even publishing one of those papers as part of a group would be an extraordinary feat for a physicist of the time, and he did it again and again.
Since high sugar levels cause plaque buildup, perhaps that explains the correlation?
They definitely have some false positives, but they also have examples of absolutely ridiculous and obvious campaigns
I'm sure there's some reason it wouldn't work, but it's fun to think about.

My claim was that some fields avoid data altogether so that they can't really be "disproved", only disagreed with. But in these cases, there are rigorous approaches that rely on data: e.g. analytic philosophy, rigorous history, linguistics, etc. and those approaches generally have a large impact.
In linguistics, Chomsky made such a huge impact on human languages because he had developed a rigorous grammar and was able to find counterexamples to many of the existing hypotheses. Chomsky had made testable hypotheses, which could only be backed up or disproven by rigorously studying human languages. And the most recent counterexamples to his grammar (e.g. that some languages lack subordinate clauses) augment rather than disprove it.
Similarly, advances in philosophy largely came from rigorous approaches -- Russell's attempts to formalize logic (and somewhat subsequent failure) resulted in Wittgenstein's formalization of the relationship to language, which had a huge impact on subsequent philosophy.
Maybe 0K (Kelvin) is special, since that implies zero gas entropy, but 0C doesn't have any magical properties.

If Fredericks and Losada had written nearly the same thing, using the same evidence but without the fancy maths, it would no doubt be accepted and lauded within English departments. Any attempts to fight it could be battled in the same way the humanities departments responded to Sokal in the 90's: by derriding him as "a pedant, a literalist and a cultural imperialist".
1. your posture is terrible (shoulders, arms, etc.)
2. you are arching / lowering your wrists
3. you are humming to yourself while playing ala keith jarrett
4. you are using the correct fingerings
5. you are playing in a way that can be sustainable for hours a day (e.g. you can play poorly for 1 hour but not for 40 hours / week)
That is, rather than lifting the bar using the legs, lifting the bar by bending back. Of course, Rippletoe would never recommend doing this, and while leaning forward doesn't guarantee improper form, it can sure make it easier.
> Experts say such technology (dynamic pricing) is most likely to be used to offer discounts to customers with loyalty status and to generate bundled fare offerings that fit the customer's profile.
They don't need AI to do that--the airlines could do this already if you log in to their site. But they don't change pricing based on loyalty; instead, they often give "perks" that are not very valuable. And because of the inflation in airline miles, it is harder and harder to get those perks in the first place -- to get a sky lounge membership through Delta requires 47,000 miles, or the equivalent of 10 roundtrip flights from LA to NYC. So, it seems disingenuous to claim that airlines will give preferential treatment to loyal customers. If anything, it would do the opposite: customers who are loyal (and trying to get the next "perk") are more willing to pay a higher price, not less willing!
