Because their equations make remarkable predictions (about the future!) that hold true time and again against a plethora of different hypothesis postulated to break their equation.

Von Neumann wrote an interesting essay open-mindedly discussing how the concept of mathematical (and scientific) rigour has changed many times. He himself jokes that he had changed his mind about it three times!

So it’s worth noting that even the idea of what constitutes mathematical rigour can and does evolve.

As he points out, too, the prevailing view of physicists in the 20th century came to be that a theory was a good theory if it either unified a set of previously disparate laws, or made predictions outside of existing observations that were then empirically validated. ie the idea that “physical laws” or theoretical models answer the “why” questions in a deep philosophical sense does not feature. (Hence the famous video where Feynman lectures the interviewer for asking a “why” question about magnetism.) That mindset does not preclude inserting terms into models where necessitated by the empirical facts. The resulting equations are merely our best models. //

I can't tell if this post is for real or not (sorry if it isn't - but in these threads I can't always tell) but if it is then: No. It doesn't work like that. External shells have no gravitational effect.

One of our early exercises in calculus / physics was the Newtonian version of the same effect. Basically as you descend into the Earth (assuming even distribution - close enough) gravitational attraction from any mass at a greater radius than you cancels out. Shoots the Hollow Earth people all to pieces - in Freshman year.

Records are made to be broken. In March 2022, we calculated 100 trillion digits of pi using Compute Engine. This is the second time we’ve used Google Cloud to calculate a record number of digits for the mathematical constant, tripling the number of digits in just three years after our world record with 31.4 trillion digits in 2019.

Check out the official blog for more details about the technical details and architecture of the calculation. And for more on the history of calculating pi, check out this post on The Keyword.

We’ve updated the API to serve all of the 100 trillion digits of pi. We’ve also published the entire results on Cloud Storage so you can download the files (caution: they are really big). //

Listen (Piano Genie)

What does Pi sound like? Each Pi digit is converted to a musical note so you can get to know Pi via music!

Piano Genie is an neural network model that allows you to play a note from 1 to 8, and intelligently map it to a great sounding piano performance. In this demo, we use each digit for [0, 7] and reuse the last digit for [8, 9], and use Piano Genie to map to the next logical note for great sounding Pi.

With 100 trillion digits and playing at 314 BPM, it'll play for 605 516 years!

The Jan. 6 Committee completely sidestepped the verifiable evidence of systemic violations of election law, illegal voting, and more. //

“The fact is we had already found many more illegal votes than the margin (11,779),” Mitchell told The Federalist, “We didn’t need to ‘find’ anything.” “We already knew which votes were illegal and had been included in the certified total,” the election lawyer said, stressing that, under Georgia law, if the “evidence established that there are more illegal or irregular votes than the margin of victory, the remedy is a new election.” //

it’s unlikely most members of Congress know of these systemic problems with our electoral system. But with midterms around the corner and Democrats likely facing a bloodbath, don’t be surprised if left-leaning politicians and their friends in the press discover substantial problems in about five months’ time.

Everyone seems to love nuclear plants, but do they forget about the tons and tons of waste you have to store somewhere basically forever?

1. Not all "radioactive" waste is the same.

Amongst the amount of radioactive waste generated by nuclear power, research, medical and a few others activities, there are different kind of waste, distinguished by their activity and their half life.

I'm most familiar with the French classification, so I'll use that one, but countries usually account for this is similar ways.

High Activity waste represent 0.2% of the volume and 94.9% of the radioactivity.

Medium Activity with long half life represent another 2.9% fo the volume and 4.9% of the activity.

The volume in France of those two categories is 4 000 + 42 000 m3. If you spread these on a football field, it raises up to 7 meters. That's the waste for the whole country.

The remainder usually is composed of shorter half life (<31 years) and medium activity, low and very low activity waste, and very short half life stuff that you can keep in storage until they get inert.

Dealing with those is significantly easier. (And generally no worse than dealing with normal industrial waste, of which we have significantly larger volumes).

2. Proper underground storage is a reliable way to deal with High Level Waste.

The underground storage projects are not stupid dig how, bury, forget process. They are designed using serious geology studies, including what can be learn from the Oklo natural reactor that ran 2 billions years ago.

The vitrified waste is in such a form that water has to actually dissolve the glass to free-up the waste (that's not happening very fast, especially given that there are a few barriers before water even comes into contact with the glass), and the storage is built in low permeability rocks were water barely flows at all. As such by the time water manages to dissolve some amount of waste, it usually has decreased significantly and gets diluted to homeopathic doses by the time it gets anywhere near surface.

What are all those streaks across the background? Satellite trails. First, the foreground features picturesque rock mounds known as Pinnacles. Found in the Nambung National Park in Western Australia, these human-sized spires are made by unknown processes from ancient sea shells (limestone). Perhaps more eye-catching, though, is the sky behind. Created by low-Earth orbit satellites reflecting sunlight, all of these streaks were captured in less than two hours and digitally combined onto the single featured image, with the foreground taken consecutively by the same camera and from the same location. Most of the streaks were made by the developing Starlink constellation of communication satellites,

One of the separators between childhood and maturity is the ability to discern the true gravity of any given situation. The seemingly unbearable anguish of teenage love gone awry fades and folds in the presence of a marriage gone wrong. The grief of a pet passing diminishes when one must say goodbye to a parent, sibling, or other loved one. It is not a case of the former possessing no meaning, but rather how life’s hammer blows places them in proper context.

Those who belong to the unfortunate fellowship of having buried a large piece of their heart alongside an immeasurable part of their life face two paths going forward. They can be forever bitter and burning with envy at those not similarly marked. Or, they can open their hearts with the understanding gained solely by painful experience to others who have unwillingly joined their ranks. The unfortunate fellowship knows, understands, and shares the grief of those freshly bereaved. //

Or, they can open their hearts with the understanding gained solely by painful experience to others who have unwillingly joined their ranks. The unfortunate fellowship knows, understands, and shares the grief of those freshly bereaved.

There is invariably an element of wondering why life on this earth must be so fragile and brief. Regardless of how fervently and firmly one believes in immortality and the promised reunion, even with the promise that He will wipe every tear from our eyes and there will be no more death or mourning or crying or pain, today there is death and mourning and crying and pain. We see it in the innocent victims of war. We see it in our own lives when we reflect on those no longer here.

The wise store treasure in heaven by freely giving love’s treasure on earth. This is the delineation between the hopeful and hysterical. The latter forever cry outrage as they endlessly preach love, yet practice only hate. If one chooses perpetual grievance over trifles, what will he or she do when genuine grief comes to call? //

The unfortunate fellowship listens far more than it speaks. There is grace in silence; comfort in unspoken sharing. An understanding presence does far more good than all the platitudes and attempts to comfort with forced cheer the world has to offer. This is Scriptural, not always quoting Scripture but rather living it by actively being there when people need one another. As the song says, before He danced, Jesus wept.

No one gets over grief. We get through it. //

Researchers have proposed that the emergence of religion was a cultural adaptation necessary for promoting self-control. Self-control, in turn, may serve as a psychological pillar supporting a myriad of adaptive psychological and behavioral tendencies. If this proposal is true, then subtle reminders of religious concepts should result in higher levels of self-control. In a series of four experiments, we consistently found that when religious themes were made implicitly salient, people exercised greater self-control, which, in turn, augmented their ability to make decisions in a number of behavioral domains that are theoretically relevant to both major religions and humans' evolutionary success. Furthermore, when self-control resources were minimized, making it difficult for people to exercise restraint on future unrelated self-control tasks, we found that implicit reminders of religious concepts refueled people's ability to exercise self-control. Moreover, compared with morality- or death-related concepts, religion had a unique influence on self-control.

Thomas Jefferson is the most enigmatic of the American Founding Fathers. The author of the Declaration of Independence, he is sometimes called the “Author of America.” As a son of the Enlightenment and the American founding, he is claimed by many sides.

And as Thomas Kidd reminds us in his splendid new biography, we still haven’t quite got Thomas Jefferson right, especially in his religious and philosophic views. What Kidd reveals is that Jefferson was, and remains, America’s chief political theologian articulating a theology of liberty. //

Jefferson the thinker, and “sect unto himself,” was a man who combined elements of “Christianity, Epicureanism, the Enlightenment emphasis on rationalism and universal rights, and the republican values of virtue, limited government, and political liberty.” The problem with discerning Jefferson’s moral universe and commitments from our standpoint comes from the fact that we live in an age of dogmatic ideology.

We impose a dogmatic reading of Jefferson, whereas Jefferson lived in age of intellectual experimentation that usually left contradictory and incompatible philosophies contesting, without seeking to resolve them. Jefferson’s mishmash of views was only possible to weave together because of the intellectual excitement and relative openness the Enlightenment afforded.

Dogmatists of the secularist post-Enlightenment want an only secular and rationalist Jefferson and misleadingly (ignorantly or otherwise) present the third president in that light. Dogmatists of the new Christian right present a misleading portrait of what Kidd describes as a “brilliant but troubled person,” as they selectively cobble together some of Jefferson’s positive comments about the relationship of Christianity and public virtue with contemporary anti-statist politics. //

Jefferson’s moral universe, a universe undergirded by a God of justice, a moral order knowable through rational inquiry, and an individual soul seeking the felicity of tranquility in all relations, becomes the spirit and flesh that comes to govern — however imperfectly, and imperfect it was — Jefferson’s life.

Jefferson’s life seeking union with the moral universe that he conceived in his mind became, in soft cultural form, the moral universe of the United States and its people, even if we don’t always realize it. We too want a God of justice, a moral order to conform to by the dictates of reason, and a tranquil soul and community where liberty abounds within that harmony under God’s justice and moral rationalism. In sum, we are still Jefferson’s children. Jefferson’s political theology has become our own. //

Because Jefferson’s moral imagination and universe drew upon many worlds, Jefferson remains an enigma for narrow-minded dogmatists who want an equally narrow Jefferson contrary to who Jefferson actually was. But, as Kidd shows in this splendid biography, we benefit by entering Jefferson’s worlds on his terms, not ours. We do ourselves, and Jefferson, a gross abuse by trying to impose our ideological presuppositions on him rather than becoming better humans by learning from the life and intellect of the Sage of Monticello. And Jefferson’s moral universe was one in which God, liberty, and man were meant to be united

It’s important to remember that a red flag law is effectively a societal nod to strip someone of their 2nd Amendment right, not because they committed a crime, but because you think they might. More accurately, someone can be stripped of their right to bear arms off of the mere accusation that they intend to cause harm. //

Red flag laws are ripe for abuse and we already have leftists with blue check marks on Twitter openly admitting that they’re ready to take advantage of them just by claiming an innocent man is insane for wanting to defend his children from people who want to take them in order to indoctrinate them with radicalized thought. //

Without the right to gun ownership, the rest of the Bill of Rights is a wishlist. Do we really want to live in a world where someone like Eric Swalwell can wave his hand and strip you of rights given to you by God?

zxcvbn is a password strength estimator inspired by password crackers. It recognizes and analyzes over 40 thousand common passwords using pattern matching and conservative estimation and filters out common first names, last names, popular words from Wikipedia and common words in many cultures, and recognizes common patterns like dates, repetitions (e.g. 'aaa'), sequences (e.g. 'abcd'), keyboard smashes (e.g. 'qwertyuiop'), and l33t speak.

Consider using zxcvbn as an algorithmic alternative to password composition policy — it is more secure, flexible, and convenient in websites that require a minimal complexity score.

What scientists know about "infantile amnesia." //

Despite the fact that people can’t remember much before the age of 2 or 3, research suggests that infants can form memories—just not the kinds of memories you tell about yourself. Within the first few days of life, infants can recall their own mother’s face and distinguish it from the face of a stranger. A few months later, infants can demonstrate that they remember lots of familiar faces by smiling most at the ones they see most often.

In fact, there are lots of different kinds of memories besides those that are autobiographical. There are semantic memories, or memories of facts, like the names for different varieties of apples, or the capital of your home state. There are also procedural memories, or memories for how to perform an action, like opening your front door or driving a car.

Research from psychologist Carolyn Rovee-Collier’s lab in the 1980s and 1990s famously showed that infants can form some of these other kinds of memories from an early age. Of course, infants can’t exactly tell you what they remember. So the key to Rovee-Collier’s research was devising a task that was sensitive to babies’ rapidly changing bodies and abilities in order to assess their memories over a long period.

When faced with these conditions, our bodies call upon a well-known mechanism to keep us from overheating: sweating. As perspiration evaporates from the skin, it cools the body’s temperature. But if the air is not only hot but also already filled with moisture, less sweat can evaporate, and this safety feature fails. In India, high temperatures and humidity are increasingly combining to pose a deadly threat—one the country isn’t prepared for.
This danger to human life is measured using “wet-bulb temperature”—the lowest temperature that air can be cooled to via evaporation. It’s determined by wrapping the bulb of a thermometer in a wet cloth and seeing what temperature is recorded. Essentially the bulb is you—or me, or Lakshmanan—the wet cloth is our sweating skin, and the temperature recorded is the coolest we can hope to get by sweating.

When heat and humidity combine to push wet-bulb temperatures past 32° Celsius, physical exertion becomes dangerous. Consistent exposure to high wet-bulb temperatures—35° Celsius and above—can be fatal. At this point the sweating mechanism shuts down, leading to death in six hours. //

At night the body should recover from the daytime assault of heat, but because nights are getting hotter, that recovery is hampered, says Dutta. Whenever people talk about the effects of heat, they usually refer to its direct effects—such as heat exhaustion and stroke, which can be fatal or debilitating—but these are only the tip of the iceberg, he says. “If heat stays high in the night, it affects the body’s homeostasis, its ability to regulate and maintain its internal body temperature.” Upset this and your cellular and metabolic activities become disrupted, which can be a driver of disease, and can even be fatal itself.

The Biden administration has initiated steps that undermine former President Donald Trump’s decision to establish the U.S. embassy in Jerusalem, media reports suggest.

The Biden State Department has set up a separate diplomatic office for the Palestinians in Jerusalem. With this move, “Washington is reversing a Trump administration policy on U.S.-Palestinian relations ahead of President Joe Biden’s possible visit to Israel” set to take place in July, The Associated Press reported Thursday.

The Biden administration’s decision seeks to rollback President Trump’s recognition of Jerusalem as the undivided capital of the State of Israel. The Washington Free Beacon, citing former U.S. diplomats, described the Biden administration’s move as “the first step to walking back the United States’ historic recognition of Jerusalem as Israel’s capital.” //

Senator Bill Hagerty
@SenatorHagerty
I unequivocally oppose this plan. It's inconsistent with the full & faithful implementation of the Jerusalem Embassy Act of 1995 & suggests the Admin is again trying to undermine America’s recognition of Jerusalem as Israel’s eternal & undivided capital.
