Capstan! A 6 century old bad ass piece of machinery. Thousands of rugged men used it to lift cargos to make a living, or travel the wild sea, or just turning it around for no obvious reason but building a body that would make even Hercules jealous.
The 20th century came, and humanity still uses ...

Scales are fun! Scales are for everything and they can express the most bizarre concepts in a more sophisticated way.
For example, there is the Hot/Crazy scale Barney Stinson made to validate his dates. It is a universal scale, with which you measure your date's feasibility and probability ending up having a Stalker ...
Do you know Elon Musk? He is a Genius Billionaire Playboy Philanthropist. Well we are not sure about the Playboy part, but when you quote Tony Stark you do it correctly.
Some people may think that he is just like Tony Stark or (if you are a DC Universe fan) Ray Palmer (AKA "The Atom ...
Flag! A piece of fabric that defines a place and a (usually) large group of people! From football club flags to National flags many events have occurred due to their existence, or they are just used as an excuse for some not so friendly and loving events! But who says that a piece of cloth ...
You all know Nikola Tesla, the brilliant multi talented Serbian-American mustached man! He was an inventor, electrical engineer, mechanical engineer, physicist and many more! One could say he was a more recent and more geeky version of Leonardo da Vinci. 
One of the most fun to watch stuff he made is the famous Tesla Coil ...

Lasers. We have talked about them two more times in the past. First was the Laser Cutting and the Gaussian beam. Then, the Laser Razor and the Wavelengths of light came by.
In both these stories, the "hot, burning and cutting" laser archetype was confirmed.
We all have in mind that lasers are for cutting ...

Our last two posts, were about that fascinating Google attempt to provide internet access to our planet's remote areas. Project Loon.
First we wanted to find out, what a balloon needs in order to fly, so we added a Hot Air Balloon Lift calculator to fxSolver's database. Then, we wondered how the electronics ...
Earlier this week, we talked about Google's project loon, and the brand new Hot air balloon lift calculator fxSolver now has.
After discussing the topic with the whole fxSolver team, G. was wondering how Google will protect its Wireless Routers from the low stratospheric temperatures. The payload of the balloon is limited, therefore they ...
