Who invented the battery? In 1800,Allesandro Volta, Italian physicist and chemist (1745-1827) made and introduced the first successful demonstration of a modern battery, commonly referred to as the Voltaic pile.⬆️ This device consisted of a series of zinc and silver plates stacked together, with each plate separated by a cloth soaked in a solution of acid and salt. This invention paved the way for revolutionary advancements in long-distance communication, including the development of telegraphs in the late 1830s and the telephone in the 1870s. However, the original Voltaic pile encountered a challenge due to the development of hydrogen bubbles as a result of chemical reactions that adhered to the electrode surfaces. This issue led to a rapid decline in the performance of the battery, rendering it of limited practical use. ℹ️ The term "battery" was coined by Benjamin Franklin in 1749 to describe a set of linked capacitors he used for his experiments with electricity.

What is the “Baghdad Battery”? 🔋 Batteries are perhaps the most prevalent and oldest forms of energy storage technology in human history. 🔋 In 1938, Wilhelm Konig, a German archaeologist, unearthed earthenware jars of approximately the size of a human fist at Khujut Rabu, located near Bagdad, modern Iraq. These 2,200-year-old jars were comprised of an iron rod within a copper cylinder, sealed with an asphalt stopper. 🔋 It is speculated that these jars were utilized by the inhabitants of the Parthian civilization, which governed the region 2,000 years ago, as electrical batteries for electroplating gold onto silver. 🔋 According to researchers, this ancient battery could produce electric current of approximately two volts. 🔋 This assemblage has become known as the “Bagdad Battery”. ❗️ However, it is important to note that there is currently no concrete evidence supporting this speculation, and even the dating of these artifacts remains somewhat disputed.

What life-forms can emerge after death? In a new study, scientist expanded knowledge about so-called “third state” that lies beyond the traditional boundaries of life and death. Researchers described how certain cells – when provided with nutrients, oxygen, bioelectricity or biochemical cues – have the capacity to transform into multicellular organisms with new functions after death. It was found that: 📌 skin cells extracted from deceased frog embryos were able to adapt to the new conditions of a petri dish in a lab, spontaneously reorganizing into multicellular organisms called xenobots⬆️ 📌 solitary human lung cells can self-assemble into miniature multicellular organisms – anthrobots – that behave and are structured in new ways, being able not only able to navigate their surroundings but also repair both themselves and injured neuron cells placed nearby. These findings challenge the idea that cells and organisms can evolve only in predetermined ways. Subscribe- t.me/askmenow

Which planet in the solar system may once have had a ring like Saturn? Surprisingly but it’s Earth that may have sported a Saturn-like ring system 466 million years ago, after it captured and wrecked a passing asteroid, a new study suggests. The debris ring, which likely lasted tens of millions of years, may have led to global cooling and even contributed to the coldest period on Earth in the past 500 million years. Using computer models of how our planet's tectonic plates moved in the past, scientists analyzed 21 crater sites around the world (across modern Australia, China, Europe, India, North America and Russia) that researchers suspect were all created by falling debris from a large asteroid between 488 million and 443 million years ago, an era in Earth's history known as the Ordovician during which our planet witnessed dramatically increased asteroid impacts. ℹ️Saturn isn’t the only planet with rings. Jupiter, Neptune and Uranus have less obvious rings, too. Subscribe- t.me/askmenow

How many “hidden turbulences” in Van Gogh's “Starry Night”? The illusion of movement in “The Starry Night” is so vivid that scientists analyzed how closely van Gogh’s depiction mirrors the actual physics of atmospheric turbulence. They discovered two “hidden turbulences”: 1️⃣the sizes of the 14 whirls or eddies and their relative distance and intensity, follow a physical law known as Kolmogorov’s theory of turbulence. ℹ️In the 1940s, Soviet Russian mathematician Andrey Kolmogorov (1903-1987) described a mathematical relationship between the fluctuations in a flow’s speed and the rate at which its energy dissipates. 2️⃣the paint, at the smallest scale, mixes around with some background swirls and whirls in a fashion predicted by turbulence theory, following a statistical pattern known as Batchelor’s scaling. ℹ️Batchelor’s scaling mathematically represents how small particles (drifting algae in the ocean or pieces of dust in the wind) are passively mixed around by turbulent flow.

Where do lavas originate from? Lavas from hotspots likely originate from a worldwide, uniform reservoir in Earth's mantle, according to a new research. The findings indicate Earth's mantle is far more chemically homogenous than scientists previously thought - and that lavas only acquire their unique chemical "flavours" enroute to the surface, interacting with different types of rocks. Besides shedding entirely new light on hotspot lavas in oceanic parts of the world, the analysis also revealed an exciting new link to basaltic lavas on the continents. These melts, which contain diamond-bearing kimberlites, are fundamentally different from magmas found at oceanic hotspots. They nevertheless prove to have the same magma "ancestor." ℹ️A hotspot is a large plume of hot mantle material rising from deep within the Earth. A line of volcanoes develops as a plate moves over a hotspot, much as a line of melted wax forms as a sheet of waxed paper is moved slowly over a burning candle. Subscribe- t.me/askmenow

Why is morning wiser than evening? People are easily seduced by first impressions, even when they turn out to be inaccurate. At the same time, expressions like ‘morning is wiser than evening’ or ‘one should sleep on it’ exist in many cultures and languages. According to a new study, sleeping on it can really help people avoid judging a book solely by its cover. In “garage sale” experiments, the researchers asked participants to look through virtual boxes. All boxes were equally valuable, but rewards were either evenly distributed or clustered at the beginning, middle, or end of the sequence. A pattern (a psychological phenomenon called primacy bias) quickly emerged: when the participants had to make a decision right away, they tended to believe that some boxes were more valuable than they really were. However, participants who weren’t asked to decide until the next day were less likely to fall into these traps and made more rational choices. Subscribe- t.me/askmenow
