Among the variety of liquids consumed by humans Water is by far the Number 1 refreshment, nutritious and necessary drink ever. Drinking Water is normally just this: a transparent newtonian liquid of low viscosity with a lot of nutritious minerals, it has no taste, basically no color, no smell , it is just clean and...

The Hidden Dangers of Kerosene in Air Travel – How safe is Kerosene to propel airplanes?
Each time when I travel by plane that’s for me an extreme life adventure. Simply because I am in the situation when I can not be anymore in full control of my life. I can only trust the science and knowledge of the few other people that surely must have a better knowledge than me... Continue Reading →
Understanding Liquid Properties: Viscosity, Surface Tension, and More
A liquid lacks both the strong spatial order of a solid, though it can have the high density of solids (a liquid has volume but doesn't have shape) and the absence of total disorder of a gas that results from the low density of gases i.e., gas molecules are relatively free of each other’s influence...

The Science of Swimming: Floatation and Cold Water Challenges
When we talk about how humans behave in relation with water, there are 2 categories of people: Those who love water, therefore they love to swim Those who are afraid of water, therefore in most cases they don’t know how to swim. Myself I am a swimmer since I was 9 year old. And by... Continue Reading →
For How Long Can We Survive Without Water?
Although water molecules are simple have a simple structure, technically such a molecule is made of 2 atoms of Hydrogen and 1 of Oxygen, the outcome being a substance noted as H2O, the physical and chemical properties of water are extraordinarily complicated. It’s not a secret for anyone that without water you won’t live long.... Continue Reading →
Aerogels: The Lightweight Material with Superpowers
Aerogels are synthetic, porous, ultralight, dry materials (unlike “regular” gels you might think of, which are usually wet like gelatin dessert). The word "aerogel" refers to the fact that aerogels are derived from gels – effectively the solid structure of a wet gel, in which the liquid component has been replaced with air or other...

HOW CAN WE MAKE ANTIMATTER?
Antimatter is by far the most expensive and difficult stuff to get. The efficiency of antimatter production and storage is extremely low. Just to for context reference, about 1 billion times more energy is required to make antimatter than is finally contained in its mass. Using E = mc2, it was found that 1 gram... Continue Reading →
STATE OF MATTER – How atoms combine and create matter?
Matter is made of atoms and the way how they combine to create structures is fundamental knowledge for our understanding of everything in the universe. Well, just to generalize a little bit, because practically speaking this is a bit of overstatement. We are still far to understand "everything", for example we know almost nothing about...

WHAT IS AEROGEL?
In a world where we say we value creativity and give out medals to reward its success, it’s odd that we still use gold, silver and bronze to do so. In a world where we have industrialized so many materials, including those we used to hold sacred, such as gold and diamond, I like to... Continue Reading →
THE MYSTERY OF MISSING ANTIMATTER – Why there is nothing there?
Antimatter is at the center of one of the biggest mysteries: why isn't there more of it in the universe? The established wisdom is that the energetic fireball of the Big Bang 14 billion years ago spawned matter and antimatter in perfect balance.This transubstantiation of radiant energy into particle and antiparticle is not a one way...
