We know the story of Electron. Now we come to its opposite i.e. Proton. How we found it and know more about it. When the electron was discovered and it was also discovered that there is a negative charge on the electron. And at the same time we also knew that the atom is a modified particle. So now there were two types of possibilities. One is that if the atom is a modified particle and the electron that is present in the atom has a negative charge, then for adjustment it is necessary that there should be another particle in the atom that has a positive charge, that cancels the negative charge of the electron. The second is that the presence of a negative charge on an electron is a lie. Now, to declare one of these two as correct, various scientists started struggling. Among them, E Goldstein set up an experiment in 1886. The experimental setup of this experiment was exactly like a cathode ridge except that the porous cathode was used here and secondly, the pressure was 0.001atm  E...

 Should I use a free VPN? By: Saqib Ali At this time, everyone around the world tries to protect their privacy on the Internet, its data should be safe and at the same time the restrictions imposed by the government should be easily bypassed.  The rise of this trend in Pakistan for a year is not a new news. The famous magazine Forbes has reported an increase in the use of VPNs in Pakistan by 400 percent, including the closure of X (Twitter) behind it. »How do VPNs work?  To answer this question, let's talk a little about VPN first. If you use the Internet from DSL at home, you create a network with a home device that includes other mobiles and computers. The traffic on this network passes through this device, which means that any other person who is on the network and has a specific software can see everyone's traffic. But if a person is using a VPN on this network, his traffic will be encrypted, but it will be known that this person is using a VPN and it can also be asce...

  Rift valley of Iceland This image is of a valley in Iceland that is part of the Thingvellir National Park - this valley is not formed by the erosion of a river but by the moving of tectonic plates away from each other - at this point two tectonic plates are separated from each other - on the right is the Eurasian plate which consists of Asia and Europe while on the left The North American plate is composed of the continent of North America - most of the boundary of these plates is at the bottom of the sea so usually not visible - but in Iceland this boundary passes right in the middle of the country The Eurasian Plate is sliding to the right due to the movement of underground magma while the North American Plate is sliding to the left, which is also expanding the valley and increasing its depth - this type of valley is Rift valley. is done because such valleys are due to the rift of tectonic plates ie moving away from each other are formed. These plates are moving away from each ...

Death Valley , situated primarily in Inyo County, southeastern California, United States, is recognized as the lowest, hottest, and driest region within the North American continent. Spanning approximately 140 miles (225 km) in length, it trends predominantly north-south and measures between 5 to 15 miles (8 to 24 km) in width. The valley is delineated on the west by the Panamint Range and on the east by the Black, Funeral, and Grapevine mountains of the Amargosa Range. It is located near the undefined border between the Great Basin and the Mojave Desert. Geologically, Death Valley constitutes a segment of the southwesternmost part of the Great Basin. It shares similarities with other structural basins in the area but stands out for its depth. Parts of the great salt pan that make up the valley's floor represent the lowest elevations of the Americas. Approximately 550 square miles (1,425 square km) of the valley's surface are situated below sea level. A point in the Badwater Ba...

What is Lunar Soil or Moon Dust? Lunar soil, also known as lunar regolith, is the layer of loose, heterogeneous material covering the solid bedrock of the Moon’s surface. Unlike terrestrial soil, which includes organic materials and moisture, lunar soil is entirely inorganic, composed of small particles created over billions of years by processes such as meteorite impacts and volcanic activity. Composition The composition of lunar soil is complex and varies depending on the location on the Moon's surface. Key components include: Silicate Glass : A significant portion of lunar soil consists of tiny shards of silicate glass formed by the intense heat and pressure from micrometeorite impacts. These impacts melt the lunar rock, which then cools rapidly to form glassy particles. Minerals : Lunar soil contains a variety of minerals, including olivine, pyroxene, and plagioclase feldspar. These minerals are common in basaltic rocks, which make up much of the Moon's mare (dark plains) r...

How to refresh the mind? Usually the frequency of our brain is 14 to 30 htz۔ We run our brains on this frequency almost all day۔ With this frequency of the brain we communicate, work, express emotions and think carefully۔ When the brain is at this frequency, it is called Beta State of mind, and in this state, the rays coming out of the mind are called Beta waves۔ When we are thinking of something lost or an event or some fantasy in our thoughts at some part of the day, then the frequency of our brain decreases to 8 to 14 Hz۔ Or when we are going to sleep, the state of drowsiness is getting worse, even then our brain has the same frequency۔ It is called Alpha state of mind and the rays coming out in this state are called Alpha waves۔ The quality of light sleep is called Theta State of mind and its frequency is 4 to 8 htz۔ Dreams also come in this frequency۔ Deep sleep is called Delta State of Mind, its frequency is 1 to 4 htz۔ No dream comes in this frequency۔ Characteristics of Alpha S...

A crow is an intelligent bird, it knows how to find food by using the small twigs of a tree as tools۔ If the thieves and robbers take him into confidence, maybe they will open the lock of the biggest bank. The brain of a crow contains 1.5 billion neurons and the same number of neurons are found in many monkey species, but there is a difference here۔ The brain of a crow and the brain of a monkey are very different in size۔ All these neurons inside this tiny brain are very close and pack, meaning the foot signals move from side to side and the communication or interaction of the brain's neurons is very good۔ This is the reason why you bend to pick up the stone, then the crow has flown on the other side۔ Its IQ level is very high and experts consider its ability to think and understand as equal to the thinking ability of a child of seven years۔ Various experiments were conducted on crows in the laboratory and games were compiled where crows took out stones through straws from eight pl...
