Trillionth Digit of ‘Pi’ Calculated

You all might be knowing pi ( ∏ ) is an irrational number with infinite digits after the decimal. There’s no end to the road of digits after it that’s why scientists and mathematicians over the time have always tried to grab its maximum number of digits as possible. But one pi lover has set a new benchmark. Shigeru Kondo, ... Read More »

How Was The Length of Metre Decided

Ever wondered how the length of metre was specified ? It’s a chain of events before we came to know about the metre we know today.   1. Back in 17th century, Christopher Wren was the person who suggested that the length of metre be the length of pendulum that takes 1s to sweep from one side to another. His ... Read More »

Why Voltage Remains Same in Parallel Combination ?

You must have studied in your school physics that when several components are connected in parallel across two points, the voltage drop is same for all of them. Why this is so ? Well we explain it from another point you must have read.   Electric field is a conservative field just like gravitational field i.e work done in electric ... Read More »

World may soon run out of Phosphorus

Phosphorous is an essential element for life. Living organisms, including humans, have small amounts and the element is crucial for driving the energetic processes of cells. In agriculture, phosphorous mined from ancient marine deposits is widely used to boost crop yields. The element also has other industrial uses. A team of researchers warns that the world’s stocks may soon be ... Read More »

Why Pressure drops in a Venturi ?

You might have studied or at least heard of Bernoulli’s principle which states that the sum of pressure head (P/specific weight), velocity head (0.5v^2)  & elevation head (z) remains constant in a streamlined flow. An important deduction of this is a “Venturi”. Venturis are used everywhere around in our lives especially in the cars (though obsolete now) Interesting question arises ... Read More »
