4 things Jules Verne got right and 4 he didn’t

Jules Verne is often considered the father of science fiction, and his unique style is known throughout the world, as he is the second translated author after Agatha Christie. He wrote about space, projectiles, underwater travel and air before any real scientific progress in the field. Even today, scientists are amazed of how well he predicted certain things; but he

What is ecotourism and why we need more of it

It’s a way to do a massive difference and it’s something which I hope more and more people will start doing.

What are tsunamis and how they form

Most waves form due to winds or tides, but tsunamis have a different cause altogether.

How Quicksand Works and How to Escape its clutches

You trek through a marsh, minding your own business, when all of a sudden *smooosh. Quicksand!

MIT celebrates 15 years of open courseware – no excuse not to learn science!

It is my personal belief that education (including higher education) should be free — or at least heavily subsidized. Unfortunately, that’s not the case in many parts of the world, where people pay exorbitant sums for university studies. But no matter where you are, there’s no excuse for not learning science. With MIT’s Open CourseWare (OCW) or websites like Coursera

How to make diamond rings at Mach speed

These set of rings/disks that are formed in the exhaust plume are known as Shock Diamonds or Mach discs (and by many more names).

ELI5: Gravitational Waves edition

The existence of gravitational waves has been confirmed. But you probably heard that already. In this post, we will break down this profound discovery into more understandable chunks.

Why some countries drive on the left and some on the right

If you’re from countries like the UK or Australia, you probably can’t understand why other countries drive on the right. If you’re from the rest of the world, you might think the British are crazy for driving on the left. But where does this striking difference come from? The history of driving on the left In 1949, most of the

The layers of the Earth

Broadly speaking, the Earth has four layers: the solid crust on the outside, the mantle and the core – split between the outer core and the inner core. The crust The crust is everything we can see and study directly. The thinnest layer of the Earth, the crust still measures about 40 km on average, ranging from 5–70 km (~3–44 miles) in depth.

Why does your voice sound so different when recorded

Why you can never hear your own, real voice without assistance (recording yourself) has to do with how sound reaches your inner ear. Basically, your inner ear picks up acoustic vibrations like the chirping of birds, rattle of the city or people’s voices and translates these vibrations into electrical signals that the brain can process as “sound”. The inner ear, however, also picks up vibrations conducted by the bones in your neck and head. This combination of internal and external vibrations produces an uniquely characteristic voice which you won’t ever be able to hear elsewhere!

Sinkholes: what they are, where do they form, and why they’re so dangerous

We will discuss what sinkholes are, how they form, and what dangers they pose.

Science Myths and Misconceptions You Probably Belive Are True

The world (and especially the internet) is riddled with false information and misconceptions – it’s time to set this straight. Here, we’ll debunk some of the most common misconceptions and also cite the real, scientific information. So, here are things which most people believe, but are actually wrong:

Food-science Sunday : The geometry of a Pringle

Mathematics is not about equations, numbers, computation or algorithms: It is about Understanding! There are many ways to understand it – the one that this post is based on is real life visualization. The Pringle shape is what is known in mathematics / calculus as a hyperbolic paraboloid. Why are Pringles a hyperbolic paraboloid? The saddle shape allowed for easier

Gyroscopic wired animals

Chickens, Cats, Owls and some more animals have this ability to keep their heads fixed on a spot, regardless of their orientation. They are gyroscopic wired.

Crown Shyness – Trees can shy away too!

Crown shyness is a phenomenon observed in some tree species, in which the crowns of fully stocked trees do not touch each other, forming a canopy with channel-like gaps.
