Mathematics
Interesting news
If mathematics is a language, then how does it seem to describe all the observed things in the universe from helical DNA structures to black holes. Mathematicians and scientists have talked about the unreasonable effectiveness of mathematics. So is mathematics inherent in the universe or is it part of the way the human brain is wired? This question is being studied and some recent research can be accessed here.
Famous Scientists
A list of all his works can be found here.

Square root of a number
The squre root of whole number is always less than the that square number ( ex; sqare root of 25 is 5, 36 is 6 etc) but in decimal it is reverse (ex; sqare root 0.8 is o.89) what is the reason? Shared by Suchetha SS, GHS Thyamagondulu.

YOUR PHONE NUMBER WILL REVEAL YOUR AGE |
Your Phone number will reveal your actual Age. It will take about 15 seconds,read and do it at the same time so that you will not lose the fun.
- Take a look at your last digit of your cell phone number
- Use this figure and multiply by 2
- Then add 5
- And then multiply by 50
- And then add the number 1765
- The last step; with this number, subtract your birth year.
Now you see a three-digit number. The first digit is the last digit of your phone number, the next two digits are your actual age! You can use the attached spreadsheet to solve this and find out why it works!!
