The Fibonacci sequence starts like this: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 and so on forever. Each number is the sum of the two numbers that precede it. It’s a simple pattern, but it appears to be a kind of built-in numbering system to the cosmos. Permission to post was granted by the video owner: @yoshisodeoka

“If a wire has too much electric current flowing through it, it will heat up. In this demonstration called “the capacitor discharge”, Daniel Davis and I took that notion to the extreme, pumping a peak current of 49,000 amps (by my calculations) through the wire to melt it and spray it across the room. It shot outwards across the room because of the Lorentz Force, the force that the electrons in the wire feel as they are moving through the wire and also through the magnetic field created by the rest of the steel wire. The reason that the steel fireworks didn’t catch anything on fire in the room is because the temperature of the molten balls of steel are high, but their tiny size means they have very little heat, and heat transfer would be the dominant factor in starting a fire this way. “ Captions, video credit and permission to post granted by @backmacsci Do you like our content?

The venue’s exterior also features 580,000 sq ft (54,000 m2) of LED displays. The Sphere measures 366 feet (112 m) high and 516 feet (157 m) wide at its broadest point. The sphere-shaped project was designed by Populous, with an interior that includes the world’s largest LED screen. MSG initially estimated the project cost at $1.2 billion. In February 2020, the company said the cost had increased to $1.66 billion as a result of design changes consisting of guest enhancements. The cost continued to increase, eventually surpassing $2 billion due to the 2021–2023 global supply chain crisis and the 2021–2022 inflation surge. With a final expected cost of $2.3 billion, it is the most expensive entertainment venue in Las Vegas history, beating out the $1.9 billion Allegiant Stadium. Like our content?

Here’s why it’s wrong👇 1. ⁠Not all of the light from the light bulb will fall on the solar panel, so some (really, most) of the energy is lost to the environment. 2. ⁠Solar panels are not 100% efficient. In fact, the maximum theoretical efficiency for normal solar cells is about 33%. That means that even if all of the light from the light bulb hit the solar panel, 66% of that energy would be lost as heat instead of converted into electricity. And since, as we noted, most of the light from the bulb doesn’t hit the solar panel, that’s a tiny amount that ultimately gets converted into electricity. 3. ⁠Not all of the electricity sent into the light bulb is converted into light. A good chunk of it is lost as waste heat. So with every step of the process, most of the energy in the system is lost as heat, and the whole thing winds down extremely quickly. - Explanation by MultiFazed (Reddit user) Like our content?

Spider silk is made of a blend of different proteins linked together into a chain, produced by special glands call spinnerets on the spider’s rear end. All spiders produce silk (some spiders can produce several different kinds), but not necessarily as webs like those depicted in Halloween decorations. Unlike silk-making insects, which tend to produce only one kind of silk, spiders make many varieties, each specialized for its own range of purposes. No one is sure how many types exist, as biologist and spider-silk expert Cheryl Hayashi recently told the Associated Press, but researchers have identified several basic categories of spider silk, each produced by a different silk gland. An individual spider can typically make at least three or four kinds of silk, and some orb weavers can make seven. Like our content? Follow 👉 @sciencefunn for more science and daily facts.🤓

Dear humanity

In the early 19th century, a new, safer method of mirror-making was invented, using silver nitrate and ammonia solution to replace the highly toxic mercury. The silver “precipitates” out of solution, forming a thin layer on the glass. This soon replaced mercury altogether. Today we use aluminium in mirrors. It’s lighter and cheaper, and crucially, not poisonous. Modern mirrors are largely produced by the wet deposition of silver or aluminium. The process begins with the cleaning and polishing of the glass substrate to remove impurities and contaminants. The glass then requires a series of coatings beginning with tin chloride because silver will not bond directly with glass. Checkout @sciencefunn for more science and daily facts.

The wind – even just a gentle breeze – makes the blades spin, creating kinetic energy. The blades rotating in this way then also make the shaft in the nacelle turn and a generator in the nacelle converts this kinetic energy into electrical energy and that’s what turns on the LEDs.
