Interesting scientific theories

Here are the top interesting theories you should to know about it.



We all know about scientific theories, as we study at our school and Colleges.first of all we will see, What is scientific theory means.

What is scientific theory ?

A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. wait, but don't confuse between fact and theory. Fact and theories both are different. In the scientific method, there is a clear distinction between facts, which can be observed and measured, and theories, which are scientists' explanations and interpretations of the facts.


Here top interesting scientific theories.


Minkowski space 


If you want to find a position of particle, you'll need a 3d dimension graph. In Real world which consists full of events. If you want to define events mathematically you need time as well. So basically events are measured by 3d space and time. This space is known as minkowski space. This concept was initially developed by the Scientist Hermann Minkowski for Maxwell’s equation of electromagnetism.





Information theory


In 1948 scientists named Claude Shannon proposed a theory to find fundamental limits on signal processing and communication operations such as data compression. Information is defined as the measure of the decrease of uncertainty for a receiver.

Shannon gave information a numerical or mathematical value based on probability defined in terms of the concept of Shannon entropy (information entropy). 


Heliocentrism



Heliocentrism is the astronomical model in which the Earth and planets revolve around the Sun at the center of the Solar System. This theory proposed by mathematician, astronomer, and Catholic cleric Nicolaus Copernicus, leading to the Copernican Revolution.

Did you know geocentric theory was supported by astronomer and mathematician Ptolemy. He believed that the Earth was the center of the Universe. The word for earth in Greek is "geo".


Heisenberg uncertainty principle





Introduced first in 1927 by the German physicist Werner Heisenberg, the uncertainty principle states that the more precisely the position of some particle is determined, the less precisely its momentum can be predicted from initial conditions, and vice versa.

If you don't understand, I will explain you with example. Let see....

Heisenberg principal define as every events are uncertain in nature. We cannot predict future. We have many plans in 2020 but we all know what happened in 2020. All plans failed because of corona virus. This is perfect example of uncertainty principle.

Whereas there many scientists believe we can predict or define events using mathematics and physics.


I will update this or give you interesting theories in another blog. What do think about this blog let know in the comment section.

Science and technology

Abhishek Sharma



 Science







We have always read about science since childhood, but what does science really mean.

So,what is science?

Science basically derived from Latin word 

"scientia",which means knowledge.

Is a systematic enterprise that constructs and organizes knowledge about the universe in the form of testable explanations and predictions


In simple words

Science provides systematic knowledge about the physical world.


Technology




Technology increasing day by day but we are not fully aware of its power.
So, what is the power technology ?
Firstly, we have to understand what technology is.

What is technology?

Technology derived from Greek word ("τέχνη",techne, "art, skill, cunning of hand"; and -λογία, logia.)
It means science of craft.
Technology can be the knowledge (science) of techniques, processes, and the like, or it can be embedded in machines to allow for operation without detailed knowledge of their workings.

In simple words
A object which reduces human effort or human hard work.

Difference between of science and technology


The words science and technology can and often are used interchangeably. But the goal of science is the pursuit of knowledge for its own sake while the goal of technology is to create products that solve problems and improve human life. Simply put, technology is the practical application of science.












Look in the image.


Importance of science and technology

It give vision to see the world differently
It helps us find out where the universe started and where is headed towards.


Science and technology are important parts of our day to day life. We get up in the morning from the ringing of our alarm clocks and go to bed at night after switching our lights off. All these luxuries that we are able to afford are a resultant of science and technology. Most importantly, how we can do all this in a short time are because of the advancement of science and technology only. It is hard to imagine our life now without science and technology. Indeed our existence itself depends on it now. Every day new technologies are coming up which are making human life easier and more comfortable. Thus, we live in an era of science and technology.


Final words

Science and technology is important but we do not have to depend completely on it.
