![]() ![]() If you label it with an eq: label, you will then be able to reference it using the reference tool. To obtain a numbered formula, you need to use the Ĭlick outside of the LaTeX block (or on another block in the document) to render the LaTeX equation: For example, type: An inline equation is $e=mc^2$. In the LaTeX block, you can insert an inline formula by typing the equation inside $.$. If you want to write more complex math, insert a LaTeX snippet in your document To insert a LaTeX block, click on Insert -> LaTeX. when you click on a different part of the document or when you enter preview mode. The number will appear when you quit editing, e.g. Note: to number your equation, select NEW LINE in the equation editor. Strange.You can click on the math symbol in the toolbar x^2y and compose both inline and new line equations (numbered) both using a visual editor with many math symbols or via a LaTeX math editor with preview. So who knows, maybe the sphere eversion will hold the secrets of the universe? We just probably have to travel through a black hole to do it or hang out with Dr. The cutting edge of a ton of fields use topological techniques and mathematics. The field shows up in really random places, from computer coding to chemistry and into the weird world of string theory, a physics theory to describe all of reality. If it's really hard to see why anybody would care about this stuff, don't worry, most people have a hard time thinking of applications of topology. Without computers, here is what the equations look like. Now, topology people can do it all the time, especially since computers can crunch the equations for us. ![]() Doing one of these mathematically was impossible to prove for a long time. Just watch the video above to see how weird a sphere eversion is. How can you turn something inside out without tearing or folding it? With math! That's impossible to do or even imagine in real life. As for whether it's a good idea to start classifying attractiveness by mathematics, that's a discussion for philosophers. It uses some complex vector mathematics, and if it works, will allow a computer to predict the beauty of a human face with more accuracy than the Golden Ratio. A whole race of Tom Cruises isn't that interesting.Īn MIT team made a better model for beauty and developed an equation that accounted for variations by focusing on the contour and shape of the face on its own, not just relying on a ratio. Or does it? Sure, having a really symmetrical face is nice, but what about variation? People's faces are beautiful for different reasons, and if everybody fit the Golden Ratio, the human race would be kind of boring. It's even possible to change pictures of faces to fit the Golden Ratio and make them even more beautiful. If a person's face matches the Golden Ratio more perfectly, then we like that person's face more. The Ratio shows up all over nature, including in human faces. One of the best ways to predict the beauty of a person is using the Golden Ratio equation. We always knew that Tool held the secrets to the universe. The same song has the time signatures arranged in the Fibonacci sequence, and when the tracks are arranged in the album according to the Fibonacci sequence, the album flows smoother. The first line has one syllable, followed by another with one syllable, followed by a line with two, on and on. The band Tool, never ones to shy away from the weird, put the sequence in their song "Lateralus." The syllables of the lines in the first verse follow the Fibonacci sequence. Not content with letting nature have all the fun, humans have used it for their own creation. It seems like the universe just loves this sequence and keeps producing it. Pupils found 8×7 nearly as tricky as former education minister Stephen Byers, who once famously answered that particular sum incorrectly. This was closely followed by 8×6, then 11×12, 12×8 and 8×12. Why does it show up everywhere? Nobody really knows. The hardest multiplication was six times eight, which students got wrong 63 of the time (about two times out of three). Big things do too: the shape of spiral galaxies follow the Fibonacci sequence, as do the shapes of tropical storms and hurricanes. We can use the Fibonacci Sequence to draw spirals and shapes, which show up in a whole lot of places (some random spirals are falsely described as Fibonacci spirals, but there are also an amazing number of real ones out there). ![]()
