5 unforgettable eternal ancient indian scientists

Hello guys, today we are going to discuss about 5 most greatest scientists of India whose radiance became dimmer with time and the most shameful part is that we could not save their research books cause the british took them to their country and thus got the reward too. The best part comes when we realize that whatsoever had been searched by our greatest scientist is a part of our "Veda" and "Purana" which had been written much and much before birth of them. So imagine how great we Indians are and what kind of people they would be who had written the "Veda" and "Purana" by going beyond time in future being present in past. We are gonna dedicate this post as a small tribute to them.

1)  The Maharshi Aryabhata(महर्षि आर्यभट): We have entitled Aryabhat as "The Aryabhat" because no body can acquire the fraction part of the position which he had. While calculating the list of greatest scientists of ancient time, Aryabhat should must acquire the first place. The time when the whole world was busy in collecting food and water for their daily need, at that time Aryabhat the great had pointed out the truth of galaxy where the other countries were not even able to calculate 1,2,3. World knows that the exact relationship between earth and sun was pointed out by Nicolaus Copernicus but most of them don't know that Aryabhat had revealed it 1000 years before Copernicus. Aryabhat said that earth completes its revolution on its own axis around the sun along with the other planets of galaxy. He also told that earth as well as moon does not shine with their own light but they shine up due to light that comes from the sun. He also revealed almost correct circumference of the earth. Aryabhat also divided time along with earth's rotation. But the invention of "zero (0)" had made him eternal forever. Zero without which considering mathematics would be futile as well as the whole digital world runs over binary number i.e, the combination of "0" and "1" had been revealed by Aryabhat. This invention along with other invention had made him eternal forever. Aryabhata wrote many mathematical and astronomical treatises. His chief work was the ‘Ayrabhatiya’ which was a compilation of mathematics and astronomy. Aryabhata also did a considerable amount of work in astronomy. He knew that the earth is rotating on an axis around the sun and the moon rotated around it. He also discovered the position of nine planets and stated that these also revolved around the sun. He pointed out the eclipses; both lunar and solar. Aryabhata stated the correct number of days in a year that is 365. He was the first person to mention that the earth was not flat but in fact a spherical shape. He also gave the circumference and diameter of the earth and the radius of the orbits of 9 planets. He also came up with an approximation of pi (π) and area of a triangle. He introduced the concept of sine in his work called ‘Ardha-jya’ which is translated as ‘half-chord’.




2)  Maharshi Kanada(महर्षि कणाद): He is known as the father of Nuclear science. He had developed the theory of atom thousand years before the birth of John Dalton who had taken all the credits of invention of atom. He said that every matter of the world has made with atoms. He also revealed three laws of motion before the birth of Newton. Indian scientist and philosopher Kanada (Hindi : कणाद) had given Vaisheshika Sutra (in 600 BCE) which describes relation between forcce and motion etc which are as follow:
a) वेगः निमित्तविशेषात कर्मणो जायते |
  Means Change of motion is due to impressed force.
b) वेगः निमित्तापेक्षात कर्मणो जायते नियतदिक क्रियाप्रबन्धहेतु  |
 Means Change of motion is proportional to the impressed force and is in the direction of the force.
c) वेगः संयोगविशेषविरोधी |
Means: Action and reaction are equal and opposite.




 3) Maharshi Baudhayana( महर्षि बौधायन):  It was ancient Indian's mathematicians who discovered Pythagoras theorem. This might come as a surprise to many, but it’s true that Pythagoras theorem was known much before Pythagoras and it was Indian who actually discovered it at least 1000 years before Pythagoras was born! Baudhāyana listed Pythagoras theorem in his book called Baudhāyana Śulbasûtra (800 BCE). Incidentally, Baudhāyana Śulbasûtra is also one of the oldest books on advanced Mathematics. The actual shloka (verse) in Baudhāyana Śulbasûtra that describes Pythagoras theorem is given below :

"दीर्घचतुरश्रस्याक्ष्णया रज्जु: पार्श्र्वमानी तिर्यग् मानी च यत् पृथग् भूते कुरूतस्तदुभयं करोति ॥"
Means: A rope stretched along the length of the diagonal produces an area which the vertical and horizontal sides make together.
Circling the square:
Another problem tackled by Baudhayana is that of finding a circle whose area is the
same as that of a square (the reverse of squaring the circle). His sutra i.58 gives this
construction:
“Draw half its diagonal about the centre towards the East-West line; then
describe a circle together with a third part of that which lies outside the square”.

Square root of 2:
Baudhayana gives the length of the diagonal of a square in terms of its sides, which
is equivalent to a formula for the square root of 2. The measure is to be increased
by a third and by a fourth decreased by the 34th. That is its diagonal approximately.
That is 1.414216 which is correct to five decimals.
Other theorems include:
Diagonals of rectangle bisect each other, diagonals of rhombus bisect at right angles, area of a square formed by joining the middle points of a square is half of original, the midpoints of a rectangle joined forms a rhombus whose area is half the rectangle, etc.




 4) Maharshi Bhaskaracharya(महर्षि भास्कराचार्य): The first principle of gravity was stated by “Bhaskaracharya” and “not Newton”. Bhaskaracharya stated the laws of gravity in the book Surya Siddhanta in 11th century. Thus the law actually exists even before the birth of Sir Isaac Newton (Newton was born in the 16th century).
Here are some of the slokas from his book Surya Siddhanta that mentions how gravitation works :
"मरुच्लो भूरचला स्वभावतो यतो,विचित्रावतवस्तु शक्त्य:।।"
सिद्धांतशिरोमणि गोलाध्याय - भुवनकोश
आकृष्टिशक्तिश्च मही तया यत् खस्थं,गुरुस्वाभिमुखं स्वशक्तत्या।
आकृष्यते तत्पततीव भाति,समेसमन्तात् क्व पतत्वियं खे।।"

- सिद्धांतशिरोमणि गोलाध्याय - भुवनकोश

“madhye samantandasya bhugolo vyomni tisthati
bibhranah paramam saktim brahmano dharanatmikam”
 [Surya Sidhantha 12th chapter 32 sloka]

This means: The spherical earth stands at the centre of earth in space due to the dharanatmikam sakti which prevents earth from falling away and helps it to stand firm.

“akrsta saktisca mahi taya yat svastham guru svabhimukham svasaktya
akrsyate tatpatativa bhati same samantat kva patatviyam khe”
[Sidhanta Shiromani, Bhuvanakosa, 6th sloka]

This means: Every object falls on the ground due to earth’s force of attraction. This force allows the sun, earth, moon and constellations to stay in the orbit.




 5) Maharshi Sushruta(महर्षि  सुश्रुत): Maharshi Sushrut (600 BCE) :Father of Plastic Surgery
  a genius who has been glowingly recognized in the annals of medical science. Born to sage Vishwamitra,   Acharya Sushrut details the first ever surgery procedures in “Sushrut Samhita,” a unique encyclopedia of surgery. He is venerated as the father of plastic surgery and the science of anesthesia. When surgery was in its infancy in Europe, Sushrut was performing Rhinoplasty (restoration of a damaged nose) and other challenging operations. In the “Sushrut Samhita,” he prescribes treatment for twelve types of fractures and six types of dislocations. His details on human embryology are simply amazing.

Sushrut used 125 types of surgical instruments including scalpels, lancets, needles, cathers and rectal speculums; mostly designed from the jaws of animals and birds. He has also described a number of stitching methods; the use of horse’s hair as thread and fibers of bark.

In the “Sushrut Samhita,” he details 300 types of operations. The ancient Indians were the pioneers in amputation, caesarian and cranial surgeries. Acharya Sushrut was a giant in the arena of medical science.

on your computer and also you can set default operating system on boot in case if you have more than one operating system.


c) Go to "startup" setting and disable those services which you think are not necessary to auto start while booting your operating system. Uncheck the services and select apply to apply the setting then select restart your computer option.


3) Uninstall the unnecessary programs: Check the list of installed softwares on your computer by going to Control panel and then programs and features. Check the list of installed programs. Uninstall the program which you think are not necessary for you. Sometimes while installing some softwares on your computer you will see some tiny software also get installed automatically with that software. It may be any virus or any unnecessary tool which takes up some space on your hard disk and affects the performance of your computer. So better to keep checking the list of installed packages/softwares on your computer regularly. Path of getting this window is given in the screenshot below.


4) Use Disk Cleanup Utility: This inbuilt tool of windows also delete the unnecessary files from your hard disk. So all you have to do is to just follow the steps below:

b) Then go to "General" tab. Select or click on "Disc Cleanup". It will calculate how much space you can free.


c) Once it gets completed, just select "ok" and then it will show you a confirmation message, so just click on "Delete Files" option there.



5) Do not play high definition games in low memory: If you don't have enough ram and graphics card in your computer then do not install hd games on your computer. As it will keep lagging your computer and thus slowing down your computer.

6) Delete unnecessary files: Delete unnecessary videos and files from your computer which are taking large space on your hard disk.

7) Do not use more than one antivirus: Some people install more than one antivirus on their computer thinking than it will enhance their computer security level. So if you one of them then let me tell you the truth that using more than one antivirus at a time can slow down your computer speed to much and much below. So better to use one antivirus at a time. Yes, you can use anti-malware software along with antivirus on your computer but do not use more than one antivirus at a time.

8) Use Cleaner softwares for your computer: Use some cleaner package for your computer. We recommend you to use CCleaner for your computer due to its excellent performance. Click on the link below to visit the download page and download cc cleaner for your operating system.

9) Manually delete program folders after uninstalling a program: Sometimes when you uninstall a program from your computer then though you have uninstalled the program but still the folder of that program exist inside of your program files whether in Program Files (*86) or Program Files. So all you need to do is manually delete those residual data of that program by going to program files folder which will be inside of the drive where you have installed your windows.

10) Use perfect uninstaller: Perfect uninstaller is a tool which will uninstall a program from your computer perfectly. It will delete all the junk files left over the drive along with the registry entry for that program inside of your windows registry. As we know when we install a program then a key associated with that program is created inside of the windows registry which is sometimes left inside the registry though after uninstalling that program. So using the perfect uninstaller tool will wipe every files, key of a program. Link to download this tool is given below. You can get it's key from internet easily. In case you don't get it then write it down below the comment section, we will give you the key for this software.

11) Disable Search Indexing: Disabling search indexing will free more space on your hard drive. To uncheck this follow steps below:
a) Right click on the drive and click on Properties.


 b) Now uncheck the box saying "Allow files on this drive to have contents indexed in addition to file properties" or see the screenshot below.



12) Defragment your hard drive: Defragmentation of your hard drive will free some space on your hard drive. Just select the drive to be defragmented and select properties option and then go to "tools" option then there would be an option saying "Defragment Now", so, select that option and follow the steps.
