​​Become a billionaire by owing NFTs! What are NFTs(NON-Fungible Tokens)

  ​​What are NFTs ? NFT stands for Non-Fungible Tokens, Non-fungible is an economic term that means an unique item without interchangeable value, for a digital artist this can be an unique piece of art, for a creator it can be a song file and for a manufacturer of software it can be a program file .  Fungible in economic terms stands for items that are non-unique and interchangeable for each other. For example currency, 1USD will buy you a chocolate, the value of the dollar bill is set and it is not unique, there are many 1 dollar bills and each bill will buy you a chocolate that costs 1USD. NFT's transforms digital assets by adding a unique digital signature, that makes a blockchain based digital certificate like many cryptocurrencies.  It secures digital assets from being copied, forged or shared as without the original digital signature, the authenticity and legitimacy of the original digital asset created will not be present.  An example, Imagine a photogra...

​​Which One Is Better Among AMOLED vs LCD displays

Hello guys, Let’s start with the pricing. Most AMOLED display smartphones always cost more than an LCD smartphone. Although the trend is changing a bit. But still, if you want to get a good quality AMOLED display you have to go for the flagship devices.  The colors are also very sharp and vibrant with the AMOLED displays. And they look much better than any LCD display. The brightness is something where LCDs stood ahead of the AMOLED display. So using an LCD display outdoors gives much better results. The last thing is battery consumption, and there is no one near to the AMOLED displays in terms of battery. As of now, all smartphones feature a Dark Mode and most of the apps and UI are dark black with a black background. This dark UI on smartphones doesn’t require any other light, it gives the AMOLED displays a boost in battery performance. Looking at all these factors and comparing AMOLED vs LCD displays, the AMOLED displays are certainly better than the LCDs. Also, the big dis...

​​What Can Affect Phone Radiation

  ​​What Can Affect Phone Radiation? The more your phone is trying to connect to the network, the more radiation it pumps out. Sometimes, you may even feel your phone heat up in your hand if you’re trying to make a call in an area with poor signal. This is evidence of your phone routing all available power to the antennae. It is really going all out to try and locate the network and connect you. So because radiation is essentially how the phone connects to the network, it is a big factor in the amount of radiation your phone gives off. When network coverage is low and there is a poor signal the phone works much harder to connect, putting out much higher amounts of radiation. Low signal has one of the biggest effects on phone radiation. Each make and model of phone is designed and manufactured differently so each will have a different amount of radiation it emits. Manufacturers have limits they must adhere to, called the Specific Absorption Rating. You can check your phone’s SA...

​​What is a Space Pen?

The Space pen is a concept design pioneered by American Engineer Paul C. Fisher, he designed the space pen factoring gravity, atmospheric pressure and variance in temperature.  Fisher developed the concept frustrated with leaking ball points for aeronautical applications and received no funding from NASA or any other government agency for its design, reeling from the controversy of 1965, it was not until 1967 that NASA after rigorous testing adopted Fishers Space Pen for astronauts who were part of Project Apollo. 400 Pens were purchased at a unit cost of 6$.  Fishers space pen could write on almost any substance from butter to steel, in any temperature ranging between -30 to 250 degrees Fahrenheit, at any angle and used pressurized ink cartridges with a special kind of ink called as Thixotropic ink. A type of viscous ink that only flowed under stressful conditions perfect for aeronautical and astronomical applications.  The body was constructed with tungsten carbide and ...

Neutron stars can be used to detect dark matter

 In today's science, the search for the nature of dark matter ranks among the greatest challenges, but the key to fully understanding this substance may well lie within the stars. Specifically, the neutron star     Scientists have inferred the existence of dark matter, but have not observed it directly. It is extremely difficult to detect dark matter particles in experiments on Earth, because dark matter particles rarely interact with regular matter. In order to detect these rare signals, we would need an enormous detector, perhaps so large that it would be impossible to build one on Earth. Natur offers an alternative option in the form of neutron stars - the entire neutron star can act as a dark matter detector. Researchers have found a way to use the information gained from these unique natural dark matter detectors more accurately in research published in Physical Review Letters. They form when giant stars explode in supernovae explosions, making them t...

A strange radio signal is coming from the Milky Way.

  A strange radio signal coming from the center of the Milky Way Galaxy has been discovered by astronomers. Researchers have been studying variations in radio waves for a long time, but the waves detected are distinct from any previously studied variations. What is unusual about this signal? According to a statement by the University of Sydney, Wang said the scientists found the new signal most strange because it had a "very high polarisation".  He explained that its light rotates with time, but that it is only in one direction at a time. Polarisation, in simple terms, describes the direction in which light waves oscillate. The study author also noted that this was a never-seen-before phenomenon. It was noted that the brightness varied dramatically and that the signal would turn on and off at random, he said, adding that the brightness varied by a factor of 100 during those episodes.  studying  radio waves for variable or transient objects is one way to unravel...

2 sci-fi concepts that are possible (in theory)

Wormholes As a story-driver, the wormhole - a shortcut through space - seems to be a fictional concept. It existed long before sci-fi writers became familiar with it under its more formal name of an Einstein-Rosen bridge. It comes out of Albert Einstein's theory of general relativity, which views gravity as a distortion of space-time caused by massive objects. Theorizing that black holes have a direct connection to each other in 1935, Einstein worked with physicist Nathan Rosen. Wormholes grew out of this analysis. In the 1980s, astrophysicist Carl Sagan decided to write a sci-fi novel, he began considering the idea of actually traveling through a wormhole. Physicist Kip Thorne developed a rapid method for traveling interstellar distances based on Sagan's advice, according to the BBC. Thorne duly devised a way — possible in theory, but highly improbable in practice — that humans might achieve interstellar travel by traversing a wormhole unscathed. After being adapted into...
