Pork-chop plot showing total delta-v needed for moving from Mars to Jupiter.
It does not make use of Oberth maneuvers or multiple orbits around the sun, so these values are a bit higher than they would be in a real mission. Given that these are intended for use in a roleplaying game, that is probably enough precision anyway.
The probability density of human-level AI implied by the answers to the Winter Intelligence conference survey. Respondents gave not only their estimates for when it was 50% chance of human-level AI but also 10% and 90%. Fitting a skew Gaussian or a triangular probability distribution to each answer, the resulting average probability density gives an estimate of the collective belief. The blue field represents skew Gaussian fits, the red line triangular fits.
The probability density in the past is due to tails of the component distributions being forced to extend before the present by certain answers.
I wrote a Matlab program that does a coherent "time delay of arrival" analysis on the seismic channels (currently only considering the Z direction). In examining the waveforms from the Mt. St. Helens event, the analysis gives a bearing to the source of 261.9 degrees. Computing a bearing using the published epicenter of the earthquake and the LHO location using the WGS84 earth model gives an actual bearing to the published epicenter of 263.9 degrees, a difference of 2 degrees. At the distance of Mt. St. Helens this corresponds to a distance of 7.5 km.
The figure at left shows the waveforms from the six seismometers at this time, after filtering with an elliptical bandpass filter with a pass band of 1-5 Hz, and decimation by a factor of ten. I estimated (using Google Maps) the location of the seismic vault in "LIGO coordinates" to be X=1040m, y=186m. The figure at right shows the "power" (not well-defined) associated with various wavevectors; the X axis gives "east slowness" and the Y axis gives "north slowness," in seconds per kilometer. The circle indicates a velocity of 5000 m/s, the approximate velocity of P-waves in rock. The seismometer locations are superimposed for directional reference only.
I am interested in whether this could be used to image local seismic noise.

Scientific discoveries can last for thousands of years, and technological inventions can be kept fresh for only a few decades, and they will be obsolete in a few hundred years. Such as electronic product updates, quite quickly. Life cycles are short, as are smart cars, smartphones, etc. Of course, the technological limit may also reach hundreds of years. Even scientific discoveries are not permanent. Tens of thousands of years later, people will have a new leap in understanding the universe and natural laws of natural phenomena. For example, people are on the moon and on Mars, and the human wisdom finds that the invention of wisdom is unbelievable. For us people on earth, we have become uncivilized ancient human beings. The intelligence quotient of lunar humans is dozens and hundreds of times that of our current Earth humans. The scientific discovery of that time was unimaginable. Mathematical, physical and chemical, natural, agricultural, medical, industrial, legal and commercial, literature, history, philosophy, classics, education, etc., everything will be renovated and mutated.
math
The science of studying quantitative relationships and spatial forms in the real world. It is produced and developed in the long-term practical activities of human beings. Originated from counting and measurement, with the development of productive forces, more and more quantitative research on natural phenomena is required; at the same time, due to the development of mathematics itself, it has a high degree of abstraction, rigorous logic and wide applicability. It is roughly divided into two categories: basic mathematics (also known as pure mathematics) and applied mathematics. The former includes branches such as mathematical logic, number theory, algebra, geometry, topology, function theory, functional analysis and differential equations; the latter includes branches such as probability theory, mathematical statistics, computational mathematics, operations research and combinatorial mathematics

Modern mathematics is a edifice built from a series of abstract structures. It is based on the innate belief of human beings in the inevitability and accuracy of mathematical reasoning, and it is the concentrated expression of confidence in the capacity, origin and power of human reason. Deductive reasoning based on self-evident axioms is absolutely reliable, that is, if an axiom is true, then the conclusions deduced from it must also be true. By applying these seemingly clear, correct, and perfect logics, mathematicians The conclusions reached are clearly unquestionable and irrefutable. Naturally, mathematics is constantly developing and alienating, and eternal mathematics is also unrealistic, mainly due to the changes in the logical thinking structure of the human brain, and mathematics will continue to mutate or alienate. Mathematical logic, natural logic, image logic, hybrid compound logic.
In fact, the above-mentioned understanding of the essential characteristics of mathematics is carried out from the aspects of the source, the way of existence, and the level of abstraction of mathematics, and the essential characteristics of mathematics are mainly seen from the results of mathematical research. Common general-purpose mathematical software packages include: Matlab, Mathematica and Maple, where Matlab is good at numerical calculation, while Mathematica and Maple are good at symbolic operation and formula derivation
(2) Dedicated math packages include:
Drawing software: MathCAD, Tecplot, IDL, Surfer, Origin, SmartDraw, DSP2000

Obviously, the result (as a deductive system of the theory) does not reflect the whole picture of mathematics, another very important aspect that constitutes the whole of mathematics is the process of mathematical research, and in general, mathematics is a dynamic process, a " The experimental process of thinking" is the abstract generalization process of mathematical truth. The logical deductive system is a natural result of this process. In the process of mathematical research, the richness of mathematical objects, the invention of mathematics by human beings, "Mathematics is a language", mathematical activities are social, it is in the historical process of the development of human civilization, human beings understand nature, adapt to It is the crystallization of a high degree of wisdom that transforms nature and improves self and society. Mathematics has a key influence on the way of thinking of human beings. It is of great significance. Mathematics, physics and chemistry, mathematics is the first priority, and it is not an exaggeration.
Based on the above understanding of the essential characteristics of mathematics, people also discussed the specific characteristics of mathematics from different aspects. The more general view is that mathematics has the characteristics of abstraction, precision and extensive application, among which the most essential characteristic is abstraction. In addition, from the perspective of the process of mathematical research and the relationship between mathematics and other disciplines, mathematics also has imagery, plausibility, and quasi-experience. The "falsifiability" feature of Matlab is suitable for the engineering world, especially toolboxes, fast code, and many integrations with third-party software, such as optimization toolboxes
The most obvious third party is comsol
Mathematica syntax is excellent, so good that it comes with almost all programming paradigms
. The understanding of the characteristics of mathematics is also characteristic of the times. For example, regarding the rigor of mathematics, there are different standards in each period of mathematics historical development, from Euclidean geometry to Lobachevsky geometry to the Hilbert axiom system. , the evaluation criteria for rigor vary widely, especially when Gödel proposed and proved the "incompleteness theorem... Later, it was found that even axiomatic, a rigorous scientific method that was once highly regarded, was flawed. Therefore, the rigor of mathematics is shown in the history of mathematics development and has a relativity. Regarding the plausibility of mathematics,
◆◆◆ Mathematics is the tool and means of physical research. Some research methods of physics have strong mathematical ideas, so the process of learning physics can also improve mathematical cognition. Mathematical logic is the study of symbolic and mathematical logic in formal logic.

The Lyapounov exponent measures how rapidly orbits diverge from each other. Here I calculated it approximatively for the Mandelbrot set.
Points inside the set converge to various cycles and hence have negative exponents. The shining centers of the components are the points that are right on a cycle. Points outside diverge to infinity, and have positive exponents. The unseen but intricate border includes both chaotic and periodic points.
Zooms of the Mandelbrot set around a point projected so that the distance to the point forms a logarithmic scale. Details on the left edge are ~10^15 times smaller than on the right edge.
The rightmost black blob in the pictures is the main "continent" of the set. Satelite sets of different sizes can be seen linked by fractal chains of varying complexity.
The colors are set using the distance estimator method.
Section through the Mandelbrot-Julia set, defined as the points (z,c) in C^2 where z_{n+1}=z_n^2+c does not diverge for z_0=z. This section corresponds to z_0 = a real number, plotted from above to show that the "equator" z_0=0 is the Mandelbrot set. The color denotes the magnitude of the smallest iterate.

En el texto MATLAB: aplicaciones a las matemáticas básicas, se abordarán una serie de problemas matemáticos utilizando el software MATLAB; así el estudiante mismo podrá estimar las bondades de esta poderosa herramienta y confrontarla con los métodos anuales.
El objetivo de este texto no es el de enseñar a programar en MATLAB, que es su aplicación fundamental, sino de mostrar sus alcances en problemas propios de las matemáticas básicas; para ello se ha seleccionado una serie de ejercicios de diferentes áreas de las matemáticas como el álgebra, la estadística y el cálculo.
Con la anterior consideración, el texto se presenta como un inicio al trabajo con MATLAB para ser empleado en cursos de apoyo e inducción; a su vez es una gran ayuda para que el estudiante cualifique su formación matemática básica y contribuir, de paso, a disminuir los niveles de pérdida y deserción de asignaturas
Here I color the Mandelbrot set based on the orbit of the points: each step adds red if it has negative real part, green if it has positive imaginary part and blue if it is outside the circle |z|=2/3. Each iteration contributes exponentially less, resulting in a color mixture.
It nicely fills in the "aura" close to the set.
