It was postponed because of the 2020 pandemic of the coronavirus SARS-CoV-2, which causes COVID-19, which has spawned a series of comic on xkcd

This concept, popular in some circles, is based on the assumption that earlier civilizations lacked the technology to build such large structures. There are also also geometric or other scientific properties to these structures, which some people assume that humans of that era would have been incapable of creating Smaller than the Planck length, which is more than a quintillion times smaller than the diameter of a proton, the ideals of Euclidean geometry no longer apply and space itself may be composed of a quantum foam where the very geometry of spacetime itself fluctuates, meaning coordinate systems based on an assumption that space doesn't change would no longer work. String theory, on the other hand, assumes that at a short enough distance the world is composed of ten space dimensions. One of these days we should probably figure that out. Here's the geometry of a typical fuel storage pool: The heat wouldn't be a big problem. The water temperature in a fuel pool can in theory go as high as 50°C, but in practice they're generally between 25°C and 35°C—warmer than most pools but cooler than a hot tub

The RGB value for a name is based on the location in the RGB color space where there was the highest frequency of responses choosing that name. This was tricky to calculate. I tried simple geometric means (conceptually flawed), a brute force survey of all potential center points (too slow), and fitting kernel density functions (math is hard). In the end, I used the average of a bunch of runs of a stochastic hillclimbing algorithm. For mostly boring notes on my data handling for. The geometric mean is less well-known but works similarly to the arithmetic mean. The geometric mean of n positive numbers is the nth root of the product of those numbers. If all of the numbers in a sequence are identical, then its arithmetic mean, geometric mean and median will be identical, since they would all be equal to the common value of the terms of the sequence. However, if the sequence is not constant, the Based on its speed and number of cars, the loop appears to have a radius of about 70 meters, which is part of why it's shown going so fast—the actual Di 4 would be just a little too slow, and would fall off the track at the top. The digital one, however, makes it around the loop in about five seconds, no problem

When New Horizonsflew by Jupiter, it gained about 4,000 m/s of velocity, while Jupiter lost about 10-21m/s.[2] The geometry is a little complicated, since they were changing both speed and direction.

Here is a very good explanation of cross-product: http://xkcd.com/199/ With complex numbers, the cross product is implemented as \( (\mathbf{a}+i\mathbf{b}) \times (\mathbf{c}+i\mathbf{d}) = (\mathbf{a} \times \mathbf{c} - \mathbf{b} \times \mathbf{d}) - i(\mathbf{a} \times \mathbf{d} - \mathbf{b} \times \mathbf{c})\ This week: Excerpts from What If articles written in a world which, thankfully, is not the one we live in: and most SCUBA equipment functions relatively well when immersed in human blood.

The problem arose from having the geometry package set single-sided pages (i.e. it set all pages to recto), and the fancyhdr package being given a specification for verso pages, which, as far as the fancyhdr package was concerned, did not exist. The solution is to ensure that all page specifications are consistent: if twoside is.

The 3rd of august XKCD was all about complex numbers and how mathematicians are too cool for regular vectors. the linked title was: I'm trying to prove that mathematics forms a meta-abelian group, which would finally confirm my suspicions that algebreic geometry and geometric algebra are the same thing XKCD is a great comic strip by Randall Munroe that takes a quirky look at the world of science. Randall recently posted a set of questions for a substitute teacher to pose to a math class that were interesting and attracted the attention of some problem-solving enthusiasts..

Fun fact: the Arithmeric-Geometric Mean can be (and is) used to efficiently compute elliptic integrals. See also this mathworld entry.

The XKCD version seemed a little extreme, but I could definitely do with a script that would make me wait 50 seconds before reading Facebook. I estimated it would take me about two hours to read/learn the API and write the code to put this together; it turns out my estimate was roughly correct. I'm a Firefox user, so it made sense for me to try and put this together as a Firefox extension. A. Usually, these odds are around 1 in 300. With 68,000 launches, then, we can expect a little over 200 nuclear accidents, which probably isn't good. But it would all be worth it if we could slow down Jupiter! Sadly, 68,000 New Horizons probes aren't nearly enough. We'd still only rob Jupiter of a tiny fraction of its speed

This performance improvement is now extended to Axes3D. This also fixes some issues with autoscaling being triggered unexpectedly in Axes3D The first issue is geometry. The biggest vertical loop which a train could conceivably go around has a radius of about 200 meters. If it's any bigger than that, even the fastest trains will fail to complete the loop. Unfortunately, a 200 meter loop is much too tight. Most high-speed trains are limited to vertical curves with radii no shorter than 20 kilometers. The reason for those limits. Using the same geometry from the Moon example, you can work out how far away you'll need to hold the camera in order to take a selfie with Venus or Jupiter: about 4 miles. Advertisement.

Geometry was one my favorite subject since 5th grade in Korea. My geometry teacher who was well known among Korean Olympiad community, I was shocked by his first few classes. Before I learned this olympiad geometry, I did all the simple geometry that appeared in school exams by hands not ruler and compass at all. When he first gave me a problem, I did what I used to do. Then he told me to. Contingency table. For cross-tabulation that aggregates by summing, averaging, etc. (rather than only by counting), see Pivot table.

Shapely provides two ways of testing the equivalence of geometries: Using the == operator, e.g. a == b Using the .equals method, e.g. a.equals(b) The result of the two methods are not identical, although it may appear that way at first.
