Subject: Mathematics Who invented zero? Although we have always understood the concept of nothing or not having, but the concept of zero is relatively new and was fully developed in India around the 5th century AD, today zero is known both as a symbol and as a number. The existence of any quantity whose application is such that it allows us to calculate calculus, perform complex equations and invent computers. Peter Gubets, Secretary of the ZerOrigIndia or Zero Foundation, said: The Indian zero, or the number widely seen as one of the greatest innovations in human history, is the cornerstone of new mathematics and physics, as well as spin-off technology, the foundation, which is based in the Netherlands. is based, researches about the roots of the number zero... Zero means none or null, and math students and professors deal with it a lot, and in most university calculations, they use very small numbers (decimal) or, like many computer programs, zero and one. @Beteacher32

Scientific: What would happen if human eyes were cameras? According to the conducted research, it was concluded that the resolution of the human eye is about 140 megapixels, and we must consider that this resolution of an eye (piscles) are unevenly distributed in it. In the center of the visual field, there are 200,000 color receptors per square millimeter, and significantly less in the periphery @Beteacher32

Another wonder of artificial intelligence Researchers have recently developed a brain implant that decodes thoughts into synthesized speech and allows paralyzed patients to communicate through a digital avatar. The implant converts brain signals into text at a rate of 80 words per minute. and focuses on speeding up phonemes versus whole words, bringing the technology closer to real-world use. @Beteacher32

Subject: Biology (insects) Can insects live without a head? In response, it should be said that when the insect's head is cut off, the insect's breathing continues because air enters its body through the openings on the insect's body. Although the connection between the nerve network and the living brain is interrupted, the nerve node in each part of the insect's body can continue the involuntary muscle activity of that part. But the problem is that the insect is fed through the mouth and after some time the insect dies of hunger! @Beteacher32
