Fact check courtesy of Google’s AI: ninjas are not mammals
No, ninjas are not mammals. This statement is a playful, humorous claim often found online, particularly on platforms like Tumblr. In reality, ninjas were historical Japanese warriors and spies, skilled in martial arts and espionage. The "mammal" claim likely stems from a misunderstanding or a deliberate misinterpretation of the term "ninja" as it relates to the Magic: The Gathering card game, where some ninja creatures are indeed mammals.

I would favor that but this conversation did start with an observation that the US exports a ton of plasma—I can’t find comprehensive data but it does look to me like all of the countries you mentioned import US plasma. Even with public administration you may need to pay people to donate

I had wondered why the Census Bureau is so weird about this! I tell them I'm female anyway because my "biological attributes of men and women (chromosomes, anatomy, hormones)" are ambiguous so I've always figured I get to break the tie how I please
Sex Definition For the purpose of Census Bureau surveys and the decennial census, sex refers to a person's biological sex. Distinction between the concepts of gender and sex In general discussions, the concept of gender is often confused with the concept of sex, and the terms are used interchangeably. The meanings of these two concepts are not the same: sex is based on the biological attributes of men and women (chromosomes, anatomy, hormones), while gender is a social construction whereby a society or culture assigns certain tendencies or behaviors the labels of masculine or feminine. These assignments may differ across cultures and among people within a culture, and even across time. Gender may or may not correspond directly to sex--depending on the society or culture or period. That means, for example, that people may associate themselves with femininity (as defined by their culture) while being biologically male. At the Census Bureau, the sex question wording very specifically intends to capture a person's biological sex and not gender. Ambiguity of these two concepts interferes with accurately and consistently measuring what we intend to measure--the sex composition of the population.

Maybe a bit petty but it seems bad to me that purported data nerd Sean McElwee doesn’t know how common denominators work.
"I think of bad relationships as 'lowest common denominator' relationships," Mr. McElwee said. "Each person pulls the other down. If one eats poorly, the other will eat poorly. But a good relationship is a 'highest common denominator' relationship."

And bus ridership is down by 37% since pre-pandemic so it won’t take a ton of new buses/drivers to accommodate a 33-38% increase www.mta.info/agency/new-y...
Bus ridership experienced a modest annual increase of 0.3% to 426 million rides, 63% of the 2019 level. This was slower than the 11% growth observed in 2022. Significant factors contributing to slower growth include rising bus fare evasion and the introduction of a fare-free pilot program on five bus routes starting in September 2023.

Some of the questions you raise here have been answered by the MTA elsewhere even though Mamdani doesn’t answer them! E.g. about a quarter of the new riders in the pilot would have taken other MTA options previously www.mta.info/document/147...
27% of new riders used other MTA bus/subway pre pilot

He got $250 billion wrong a couple days ago too
The European Union, which was formed for the primary purpose of taking advantage of the United States on TRADE, has been very difficult to deal with. Their powerful Trade Barriers, Vat Taxes, ridiculous Corporate Penalties, Non-Monetary Trade Barriers, Monetary Manipulations, unfair and unjustified lawsuits against Americans Companies, and more, have led to a Trade Deficit with the U.S. of more than $250,000,000 a year, a number which is totally unacceptable. Our discussions with them are going nowhere! Therefore, I am recommending a straight 50% Tariff on the European Union, starting on June 1, 2025. There is no Tariff if the product is built or manufactured in the United States. Thank you for your attention to

My “I designed my AI with safety measures to limit the risk of it being misused specifically for the development or acquisition of chemical, biological, radiological, and nuclear weapons” t-shirt has people asking lots of questions already answered by my shirt
"You could try to synthesize something like COVID or a more dangerous version of the flu-and basically, our modeling suggests that this might be possible," Kaplan said. Because of that, the company released the Al model with safety measures it said are "designed to limit the risk of Claude being misused specifically for the development or acquisition of chemical, biological, radiological, and nuclear (CBRN) weapons."

I happen to be studying for the CPA exam and it has a very condensed section on basic microeconomics concepts, presented very conventionally. Here's the part where it says that nondiscretionary purchases have inelastic demand curves.

I'm comforted by the conclusion in this paper that both the length and ease of amendment have strong positive effects on longevity—you want the constitutional settlement to be clear but also have it be subject to renegotiation/democratic contestation.

But in flight mechanics (both in space and atmospheric flight), which is the context in which people talk about g-forces/accelerations, the equivalence principle is always assumed. Freefall or orbit is 0g. Sitting on earth is 1g.
For example, a force of 1 g on an object sitting on the Earth's surface is caused by the mechanical force exerted in the upward direction by the ground, keeping the object from going into free fall. The upward contact force from the ground ensures that an object at rest on the Earth's surface is accelerating relative to the free-fall condition. (Free fall is the path that the object would follow when falling freely toward the Earth's center). Stress inside the object is ensured from the fact that the ground contact forces are transmitted only from the point of contact with the ground.

Now, you might say, sure that's true but who cares? On a small scale we can just use Newtonian physics with an accelerating reference frame, and treat gravity as a force. And you can! It works fine.
For weak gravitational fields, the results of general relativity do not differ significantly from Newton’s law of gravitation. But for intense gravitational fields, the results diverge, and general relativity has been shown to predict the correct results. Even in our Sun’s relatively weak gravitational field at the distance of Mercury’s orbit, we can observe the effect. Starting in the mid-1800s, Mercury’s elliptical orbit has been carefully measured. However, although it is elliptical, its motion is complicated by the fact that the perihelion position of the ellipse slowly advances. Most of the advance is due to the gravitational pull of other planets, but a small portion of that advancement could not be accounted for by Newton’s law. At one time, there was even a search for a “companion” planet that would explain the discrepancy. But general relativity correctly predicts the measurements. Since then, many measurements, such as the deflection of light of distant objects by the Sun, have verified that general relativity correctly predicts the observations.

Einstein's insight is that this is not a coincidence: what gravity *is* is mass creating curvature in spacetime, not truly a force. When we are standing on earth, we *are* accelerating—away from the center of the earth.
The general theory of relativity challenges this long-held assumption. Only empty space is flat. The presence of mass—or energy, since relativity does not distinguish between the two—distorts or curves space and time, or space-time, around it. The motion of any other mass is simply a response to this curved space-time. (Figure) is a two-dimensional representation of a smaller mass orbiting in response to the distorted space created by the presence of a larger mass. In a more precise but confusing picture, we would also see space distorted by the orbiting mass, and both masses would be in motion in response to the total distortion of space. Note that the figure is a representation to help visualize the concept. These are distortions in our three-dimensional space and time. We do not see them as we would a dimple on a ball. We see the distortion only by careful measurements of the motion of objects and light as they move through space. Figure 13.29 A smaller mass orbiting in the distorted space-time of a larger mass. In fact, all mass or energy distorts space-time.

Ok! The starting intuition for general relativity is the "equivalence principle": if I'm in a sealed room sitting on the earth's surface, or in a sealed room accelerating through deep space at 1g, I will have the same experience: if I drop something it will fall, I feel the ground pushing up, etc
According to general relativity, objects in a gravitational field behave similarly to objects within an accelerating enclosure. For example, an observer will see a ball fall the same way in a rocket (left) as it does on Earth (right), provided that the acceleration of the rocket is equal to 9.8 m/s2 (the acceleration due to gravity on the surface of the Earth).

I beg you, look up either general relativity or g-force to understand how these words are used before you correct people. Acceleration is described relative to the freefall condition, general relativity explains why this is correct (freefall is constant velocity thru curved spacetime)
For example, a force of 1 g on an object sitting on the Earth's surface is caused by the mechanical force exerted in the upward direction by the ground, keeping the object from going into free fall. The upward contact force from the ground ensures that an object at rest on the Earth's surface is accelerating relative to the free-fall condition. (Free fall is the path that the object would follow when falling freely toward the Earth's center). Stress inside the object is ensured from the fact that the ground contact forces are transmitted only from the point of contact with the ground.

Here’s more from ChatGPT on how flight uses the relativistic framework and “1g of acceleration” means not accelerating relative to the earth
ChatGPT v In an atmospheric flight context, what does it mean to be under 1g of acceleration? In an atmospheric flight context, saying an aircraft (or pilot) is under 1g of acceleration usually means: • The net acceleration experienced by the aircraft (and by people inside) feels the same as normal gravitational acceleration at Earth's surface - about 9.8 m/s downward. • Importantly, it also means the lift force generated by the wings exactly balances the gravitational force nulling downward. • For the pilot. it feels like "normal weiaht" — Ask anything 叉 ... ChatGPT can make mistakes. Check 7:494 ・？100 chatgpt.com 凸 ChatGPT v • For the pilot, it feels like "normal weight" - no extra or reduced forces pressing them into or pulling them out of their seat. In practical flight terms: • If an airplane is flying straight and level at constant speed, it is typically at 1g - lift equals weight, and there is no vertical acceleration. • If the airplane pulls up into a climb, or banks into a turn sharply, the pilot may experience more than 1g (for example, 2g in a tight turn — they feel twice as heavy). • If the plane dives or falls freely (like in a parabolic "zero-g" flight), the apparent g-forces felt can dror & low 1g, even to 0g.

You could even ask ChatGPT to explain it to you
ChatGPT v • Experiencing 1g of acceleration: From a physics perspective (specifically, in terms of forces), you are experiencing an acceleration. Gravity pulls you downward with a force equivalent to 1g (about 9.8 m/g₴ ), but the ground pushes up on you with an equal and opposite "normal force." This upward force counters gravity and keeps you from falling. However, in the framework of general relativity (Einstein's view), standing still on Earth is equivalent to accelerating upward at 1g, because you are being prevented from following your natural "free fall" path through spacetime.

Google thinks ten minutes on earth can kill you
A sustained acceleration of 1 g for 10 minutes would cause significant physiological effects, potentially leading to loss of consciousness or even death. While 1 g is the standard acceleration experienced on Earth due to gravity, prolonged exposure at that level can be dangerous. Prolonged 1 g is dangerous: While 1 g is normal for short periods, sustained acceleration at that level can lead to serious physiological effects, including: • Loss of consciousness. • Cardiac arrest. • Brain damage.
