The Aizawa attractor, a particular case of the Lorenz attractor, has this system of differential equations: dx = (z-b) * x - d*y dy = d * x + (z-b) * y dz = c + a*z - z³/3 - x² + f * z * x³

Well, Bohr's model of the Atom has not held up; and Einstein's "Space-Time" gravity view is still Sci-Fi. And neither could explain how an Atom creates Gravity. All that is known about Gravity today is, Gravity gets stronger with increasing density of Atoms in a volume.

It’s absolutely misguided to think that scientists using bloated, overly complicated language in their papers are somehow impressive to other scientists In reality the opposite is the case. It’s impressive if you can communicate complicated ideas in simple terms.

One of the strangest coincidences in physics is the fact that Newtonian fluid dynamics in three dimensions is exactly equivalent to a scalar field theory in FOUR dimensions, with a Lorentzian signature metric. I know of no intuitive reason for this to be true, but it is.

I'm looking for recent (<10y) #compchem papers that predicted phenomena before any experiments. It's for a talk on this topic. Do you know any? Please send me the DOI.

This "frugal CRISPR kit" costs about $2. It includes a cell-free extract (no living cells), plasmids encoding colorful proteins, and Cas9 + guide RNAs. Students express colorful proteins in the extract & then use CRISPR to cut the protein-coding genes, leading to loss of color.

What you are seeing is the end of an officially enforced MASS DELUSION. This was always almost certain to happen. Joe Biden has been mentally unfit for his entire administration. And this has been clear to EVERYONE who isn't compromised. Think of *everyone* who stayed silent. The psychiatrists. The neurologists. The geriatric medicine specialists. The party leaders. The news organizations. The universities. Essentially all the experts. That is why I sound crazy to many of you. But we were right and...somehow...somehow...they were all silent. From the Februrary 19, 2024 release of Modern Wisdom: youtube.com/watch?v=p_swB_KS… --------Transcript------- CHRIS WILLIAMSON (1:26:40): We’re way too close [in February 2024] to the 2024 election for anybody to be cleared out now. ERIC WEINSTEIN: Really?? CW: I mean what's going to happen between now and November? EW: I don't know….I mean how old is Joe Biden? CW: I don't know. EW: Okay, what are the odds that Joe Biden has a debilitating event between now and November? Including death. So he runs a 1 in 20 chance of dying in any given year or above that, so I don't think you know whether he's even going to make it to November. CW: [Biden is] 81. EW: Yeah. You have no idea what [is about to happen]! It's a million years between now and November. ------------- End Transcript--------- We've had an assasination attempt and a campaign abandonment. It is still a million years between now and November. As I said in Februrary, I *still* don't know which names will be on the ballot. If you still think you do, how the heck do you know? Really?? You don't. You never did. This is Managed Reality. And it just cracked. Again. You are living through wall-to-wall, cradle to grave OFFICIAL mass delusions. This is governmentally enforced mass disinformation and it is coming from inside the house. And you will know the tiny number of people pointing this out to you as they will be PRE-BUNKED as grifters, charlatans, narcissists, gurus, self-important blowhards, attention seekers, etc. Wake up. If not now, when?

The hilarious part is that Planck, IIRC, came up with the number as a placeholder, until we could figure out what really goes there.

Why's Einstein there? His maths teacher called him a 'lazy dog' and he had to get help with the maths for his Theory. He was a physical imaginer not an abstract thinker. As a boy he asked himself what it would be like to ride a light beam. It probably all came from that.

There is nothing supernatural about the process of self-organization to states of higher entropy; it is a general property of systems, regardless of their materials and origin. It does not violate the Second Law of thermodynamics since the decrease in entropy within an open system is always offset by the increase of entropy in its surroundings. - Ervin László

Gabriel's Horn, also known as Torricelli's Trumpet, is a geometric figure that has the paradoxical property of having infinite surface area but finite volume. It is formed by revolving the curve y = ¹⁄ₓ around the x-axis from x = 1 to infinity.

Before the advent of quantum mechanics, classical physics predicted that black bodies (perfect absorbers of radiation) should emit radiation with infinite energy at ultraviolet and shorter wavelengths, a prediction clearly at odds with physical reality. This problem, known as the ultraviolet catastrophe, was resolved by Max Planck in 1900, who introduced the idea that energy is quantized, laying the foundation for quantum mechanics.

Several months after Einstein presented his papers on General theory of relativity in 1915, a young German soldier serving at the Russian front solved Einstein's field equations. His solutions revealed the existence of black holes.

Oliver Heaviside also introduced several terms and symbols that are still widely used in mathematics and physics today? For example, he coined the words impedance, admittance, conductance, and permeability. He also used the symbols j for the imaginary unit, ∇ for the del operator, and / for division. Heaviside was also a prolific writer, publishing many papers and books on various topics. He had a distinctive and witty style of writing, often using humour and sarcasm to make his points. He was not afraid to criticize the errors and shortcomings of other scientists, even the most eminent ones. He once wrote: “Mathematics is of two kinds, Rigorous and Physical. The former is Narrow: the latter Bold and Broad. To have to stop to formulate rigorous demonstrations would put a stop to most physico-mathematical inquiries. Am I to refuse to eat because I do not fully understand the mechanism of digestion?” Heaviside was also fond of poetry, and sometimes composed verses to illustrate his ideas. Here is an example of a poem he wrote about the Heaviside step function, a mathematical function that he invented: Heaviside's Function by Oliver Heaviside There was a young fellow named Heaviside Who had a most wonderful brain He could make a step function With very little instruction And he did it again and again

The Chudnovsky algorithm has been used to achieve numerous world record calculations of π, such as 2.7 trillion digits in 2009, 10 trillion digits in 2011, 22.4 trillion digits in 2016, 31.4 trillion digits in 2019, 50 trillion digits in 2020, 62.8 trillion digits in 2021, and 100 trillion digits in 2022.
