Below you will find some of the hidden features searchs (Easter eggs) of Google. Their name in Google's slogan is Easter eggs, apparently coming from Kinder Surprise. 
The Easter eggs you can find on Google, but do not be sure they will stay, as these hidden features may disappear at any time. We have personally tested each of the things mentioned below and at the time of writing this article they all work. Let's go then:
1. Real Easter egg
Look for the following:
1.2 + (sqrt (1- (sqrt (x ^ 2 + y ^ 2)) ^ 2) + 1 - x ^ 2-y ^ 2) + 10000 / 3) from -5 to 7
What we are seeing here is the awesome power of Google's hidden calculator.
2. Google In 1998
Search for "Google In 1998" and you will get a functional page of the service as it was in 1998 when it started.
