The Woman Behind the First Manned “Journey to the Moon”

Margaret Hamilton The Woman Behind the First Manned “Journey to the Moon” Background “We choose to go to the Moon''. These words by the then US president John F. Kennedy, addressing the crowd of prestigious Rice University in 1962, was no sort of relief for Americans who feared the overwhelming Soviet Union and the US falling short in what was to be ‘first’ to land man on the moon. Soon after, the courageous and ambitious ‘Journey to the moon’ had its first dedicated mission ‘The Apollo Program’ which despite initially being destined for a trip to Mercury shifted its ambitions a little close to the earth, the lunar surface. The Apollo program, by NASA, was successful in landing the first Manned spacecraft on the Lunar surface just 7 years after its rejuvenation under President John F. Kennedy. The first Lunar module landed the likes of Neil Armstrong, Micheal Collins, and Edwin Aldrin but little do they know the mind behind the software that orchestrated the mo...

Understanding Prime Numbers

One of the most intriguing things in Mathematics is Prime Numbers. To put it in simple words, the numbers are all out in the "number world" all by themselves. They have no relatives i.e. factors other than themselves and the "universal factor" called 1. So, what's really unique about prime numbers? Over the history of Mathematics and especially Number Theory, many theorems based on prime numbers have been proposed. The best thing about prime numbers is that they are the building block of the whole number system. If you add two prime numbers, it always gives an even number greater than 2. Likewise, if you were to pull off a number line so infinitely long then most of the numbers except for the prime number themselves, would just be the multiple of prime numbers or in other words products of prime numbers. To put into Euclid's own words, " Every natural number can be represented as a product of prime numbers. " Here's a fun activity f...

Why is any number over 0 undefined or what we say infinity?

Why is any number over 0 undefined or what we say infinity? We are used to dividing a certain number by another or by the same number since we started learning mathematics. That’s not a big deal. But here’s one big deal that we are always warned about i.e., to divide any number by zero (0). But Why? Because you get infinity when you do so. But how and why we tend to get so when we divide any number by zero? Let’s have a look at it to better understand!!! ▪ Firstly, what’s multiplication? Nothing but repeated addition. Example: 2×3=6 which means we need to add 2 thrice to get 6. ▪ And secondly , what’s division? Nothing but repeated subtraction unless we get zero. Example: 15/5=3 which means subtracting 5 thrice from 15 to get 0. i.e, 15-5-5-5=0 But let’s check in case of 1/0. Accordin...
