CYCLONE

Today we are going to know about cyclones like What they are, How they form & Why they are so destructive. Let's start
What is Cyclone 🌀 ???
 cyclone is a large scale air mass that rotates around a strong center of low atmospheric pressure. Cyclones are characterized by inward spiraling winds that rotate about a zone of low pressure. The largest low-pressure systems are polar vortices and extratropical cyclones of the largest scale.



To  understand the formation of a cyclone first we have to know about tropical region, winds movement & the most important coriolis force.

Tropical Region 
These are the regions which lies between equator & Tropic of Cancer in northern hemisphere and between equator & Tropic of Capricorn in southern hemisphere. Since Tropical Region is longitudinally at the centre of earth therefore it hit by the straight dun rays as compared to other regions where sun rays hit slantly. So, due to the straight sun rays oceans more heated in Tropical Region.



Wind Movement
Wind moves from high pressure area to low pressure area. Low pressure area are created due to heat. As I said earlier that tropical region is much heated than other regions therefore tropical region become low pressure area and polar regions become area of high pressure. Since wind moves from high pressure to low pressure, wind starts moving from polar region to tropical region.


Coriolis Force
As we see sun rise from East and drop in West direction because earth moves from East to West direction and due to this movement of earth a force develops called coriolis force. Since earth is a sphere and it is much thicker at the equator than the poles i.e it have more speed at the equator. So if  anything coming from poles to equator get deflected in the East direction due to the Coriolis Force. Due to the coriolis force winds in northern hemisphere turn right & winds in southern hemisphere turn left.


How they form?
When we look at a cyclone we find that always there is a center of cyclone which have low pressure as we know that winds moves from high to low pressure area we come to note that cyclone consists of cool air coming from high pressure area which surrounded by the central low pressure area this region is called eye of the storm or center of storm.

Let us consider a spot in the tropical region which is worm so air at this spot become warm and go up to fill the void created by this cool air from surrounding comes and the air that go up earlier cools due to the reason that air cool up as altitude goes up. Now the cool air keeps getting attracted towards the centre because that's where the warm low pressure zone is while moving towards the centre the cool air just getting deflected. Now thats create a spin in a anti clockwise direction in the southern hemisphere the coriolis effect moves air to the left opposite to what happened in the north hemisphere as a result the spinning of cyclone is in clockwise direction in southern hemisphere.



Why they are so destructive ?

Primary Hazards:

Primary hazards include strong winds, heavy rains, and storms. The sea level rises abnormally near the coasts as a result of which the low-lying areas near the coastal regions get submerged, drowning humans, their live stocks, and their inhabitations, destroying vegetation and soil fertility. Very strong winds damage the houses, trees, communication systems etc. resulting in huge loss of life and property.


Secondary Hazards:

Secondary hazards include floods, fire, and freshwater flooding. Heavy and prolonged rains cause floods in rivers which cause submergence of the nearby inhabited regions, erosion of valuable farming lands and destruction of buildings. Strong winds in forest regions result in forest fires which spread with the intensity of cyclonic winds.

HOW TO TIME TRAVEL


We have many ways to time travel but none of them is proved yet

  1. Traveling with the speed of light: According to the theory of relativity when an object travel with the speed of light, time passes slower for him than others.
  2. Huge gravity: when gravity become huge like of black hole, light also can't escape from its gravity and time become slower for an object approaching towards that huge gravity area.
  3. Multiverse: according to Quantum Mechanics multiverses exists. There is not a single universe where time changes but there are multiverses and in different universes different timelines exists.
  4. Tipler cylinder: according to american physicist Frank Tipler, if we move around a cylinder of infinite length having electric and magnetic fields then we can go in future or past.
  5. Wormholes: from centuries peoples thought that wormholes are roads built in higher dimensions that connects time and space.
  6. God particle: on 14 March 2013, scientists discover Higgs boson and they believed that this particle can do time travel.
  7. Cracks in universe: astronomers found that there are cracks in the universe wich can give birth to time loops.
  8. Black Holes: due to huge gravity of black holes physicists think that the trough it we can do time travel.

FALSE MEMORY



When I was a  child in school i never celebrate my birthday in my school because most of the time my birthday comes on holidays. One of my schoolmates name Sam and he was my classmate till the graduation. One day during lunch I said to Sam that I am a unlucky guy because I never celebrate my birthday in school and he replied that '' You celebrated your birthday when we were in 7th standard , you weared black clothes also " his that reply shoked me completely and I thought that how it is possible it was my birthday and why I don't remember that? And why I weared black clothes? That was not a funeral it was a birthday. I asked about that day to others they also don't know.


After a great reserch on internet I come to a point that it may be Mandela effect or Multiverse. But that theory which I thought was most accurate and it was FALSE MEMORY.
Sometimes people have memories which are not of their own. Let's understand how these memories form and why. From centuries psychologists try to understand it. In  1974, Elizabeth and John Palmer conducted a study to investigate the effects of language on the development of false memory. The experiment involved two separate studies

In the first test, 45 participants were randomly assigned to watch different videos of a car accident, in which separate videos had shown collisions at 20 mph (32 km/h), 30 mph (48 km/h) and 40 mph (64 km/h). Afterwards, participants filled out a survey. The survey asked the question, "About how fast were the cars going when they smashed into each other?" The question always asked the same thing, except the verb used to describe the collision varied. Rather than "smashed", other verbs used included "bumped", "collided", "hit", or "contacted". Participants estimated collisions of all speeds to average between 35 mph (56 km/h) to just below 40 mph (64 km/h). If actual speed was the main factor in estimate, it could be assumed that participants would have lower estimates for lower speed collisions. Instead, the word being used to describe the collision seemed to better predict the estimate in speed rather than the speed itself.

The second experiment also showed participants videos of a car accident, but the phrasing of the follow-up questionnaire was critical in participant responses. 150 participants were randomly assigned to three conditions. Those in the first condition were asked the same question as the first study using the verb "smashed". The second group was asked the same question as the first study, replacing "smashed" with "hit". The final group was not asked about the speed of the crashed cars. The researchers then asked the participants if they had seen any broken glass, knowing that there was no broken glass in the video. The responses to this question had shown that the difference between whether broken glass was recalled or not heavily depended on the verb used. A larger sum of participants in the "smashed" group declared that there was broken glass.

In this study, the first point brought up in discussion is that the words used to phrase a question can heavily influence the response given. Second, the study indicates that the phrasing of a question can give expectations to previously ignored details, and therefore, a misconstruction of our memory recall. This indication supports false memory as an existing phenomenon.

Replications in different contexts (such as hockey games instead of car crashes) have shown that different scenarios require different framing effects to produce differing memories.

Conclusion: False memory is a phenomenon where a person recalls something that did not happen or recalls it differently from the way it actually happened. Suggestibility, activation of associated information, the incorporation of misinformation and source misattribution have been suggested to be several mechanisms underlying a variety of types of false memory phenomena.

False memories are a component of false memory syndrome (FMS).

FUTURE OF HUMANITY

FUTURE OF HUMANITY  




Talking about the future of humanity fantasies all of us because all of us want to know that what will be the next level of humanity. Many a time when we think about our ansisters who live into a cave then we have a curiosity to know that will be our future.
Actually it is very difficult to make predictions but after analysing a lot of things we can make a prediction which can be accurate a lot. So to predict the future we have to understand how our ansisters of 1900 think of us, they will think we are wizards or sorcerers who have magic mirrors called mobile phones, flying carpets called jet airplanes.
So, i think if we look our descendant of 2100 they will be look like hindu gods like Hanuman who is immortal because i think in future the genetic engineering will be so adwance that we can take out the age causing geans out of our DNA anf became immortal.
Like Sanjay of Mahabharata, we will have more advanced drones who don't need any type of maintenance or they be self healing as today we are at the point where Lamborghini has created the world's first self-healing sports car. The Terzo Millennio, which translates as third millennium in Italian, has the ability to detect and repair cracks in its body work.
I think that the industries which will be the biggest in 2100 are mainly ARTIFICIAL INTELLIGENCE, NENO TECHNOLOGY, BIO TECHNOLOGY.



Ofcourse, now most of you have a question that will one day A.I became dangerous for humanity? Yes, but only if they become self aware. I think until they become self aware they are like workers for us. Also you have a question that will it reduce employment? No, because A.I reduce employment in one sector but increase employment in another sector. For example, when automated teller machine (A.T.M) was introduced people thought it will reduce employment in banking sector. But some times predictions also fail for example when internet was first introduced at CERN (the European Organization for Nuclear Research) so that scientists from all over the world can share their reserch and public thought that one day internet become a place for high culture art and society but today we all know that around 4% of internet if only filled by pornography.
