Here we talk about the most common type of solids. Use them on daily basis. If you stop for a second and look around you, you will notice that most of the objects that you have are either made up of metals or contains a metal. For example, your watch has metal components, and your... Continue Reading →
WHAT ARE THE MOLECULAR SOLIDS?
During the wintertime in case you are blessed enough to be in a place where it's snowing, if you are like most school kids, you get pretty excited about snow days. On your day off, you might go outside and play in the snow as you watch the snowflakes fall. When a snowflake lands on... Continue Reading →
WHAT ARE THE IONIC SOLIDS?
This category of solids have very much to do with our food. We literally eat Ionic Solids. But let's dive deeper a little bit. WHAT IS A IONIC SOLID? By definition of the word “ionic”, indicated that we are dealing with something that is obviously related to, or involves ions. A ION is a particle,... Continue Reading →
WHAT ARE THE COVALENT NETWORK SOLIDS?
Solid is the 1st state of matter and also the most studied and used. Anyone entering into materials science engineering the 1st stage of study starts with learning and understanding solids. In my previous article I was briefly introducing the concept of SOLID, what is it, how does it occur and what are it main... Continue Reading →
THE 1st STATE OF MATTER – SOLID
The Periodic Table of Elements currently contains 118 elements we have knowledge about, yet the element 118 is definitelly not the last one. The same I can say about the states of matter. Before anything else let's recall the definition of matter. MATTER is referred to as anything that has mass and occupies space. So... Continue Reading →
MERCURY: The atmosphere on the smallest planet in our solar system
Mercury is a planet without much of atmosphere and its surface full of craters tells us about the great cosmic bombardment a.k.a. the Late Heavy Bombardment which is a hypothesized event thought to have occured approximatelly 3.9 billion years ago. It's not easy to find information about the early life of this globe, because Mercury... Continue Reading →
MERCURY: The 1st Planet from the Sun and smallest in our solar system.
All the technology we have so far is based on materials available on our planet. At least for now. However at one point in time as technology continues to advance we might be able one day to exploit natural resources available in our Solar Sistem. Except Earth there are 4 bodies outhere we can consider... Continue Reading →
MECHANICAL DESIGN ENGINEERING – Geometrical Dimensioning and Tolerancing_What is the TOTAL RUNOUT tolerance?
Description Definition: Total Runout is how much one entire feature or surface varies with respect to a datum when the part is rotated 360° around the datum axis. Total runout controls both the amount of variation in the surface as the part is rotated, but the amount of variation in the axial dimension. Both radial... Continue Reading →
MECHANICAL DESIGN ENGINEERING – Geometrical Dimensioning and Tolerancing_What is the CIRCULAR RUNOUT tolerance?
Runout is one of the oldest and simplest concepts used in GD & T. Maybe as a child you stood your bicycle upside down on the ground and spun a wheel. If you fixed your stare on the shiny rim where it passed a certain part of the frame, you could see the rim wobble... Continue Reading →
The Clouds – Why clouds are mostly white?
Recalling my trip to New York by plane back in 2019, as I gazed out the window into the whiteness, I found it hard to reconcile a cloud as being fundamentally liquid. The individual droplets that make up a cloud are of course too small to see, but they are also transparent. So why are... Continue Reading →
The Clouds – Why clouds are neither pure nor innocent and how humans can artificially create them?
I use to travel by plane every year, sometimes for holiday; sometimes for business. Everytime when I am up there I take a look out of the window and I see the clouds just below the plane I am in. They appear to be objects, sometimes fluffy as if made of wool, and sometimes denser,... Continue Reading →

LEAN MANUFACTURING – DESIGNING A CAR – The Techniques of Lean Design
It's wonderful to know that new products can be produced faster with less effort and fewer errors. However, innovations are most useful when they are available to everyone and practices at General Motors, Volkswagen and the other mass producers, lag far behind. I know because myself I was doing this for years and during the... Continue Reading →
MECHANICAL DESIGN ENGINEERING – Geometrical Dimensioning and Tolerancing_What is the SYMMETRY tolerance?
Among the 14 used GD & T symbols in the category of Location Tolerances there are 3 types. 1. The Position Tolerance 2. The Concentricity Tolerance 3. The Symmetry Tolerance From these 3 tolerance types, only the Position Tolerance is often used as it is also easy to measure. The other 2 are in general... Continue Reading →
MECHANICAL DESIGN ENGINEERING – Geometrical Dimensioning and Tolerancing_What is the CONCENTRICITY tolerance?
The functionality of a part in an assembly is usually well defined by the 4 form tolerances (straigthness, flatness, circularity and cylindricity) and among the orientation tolerances by the 3 most frequent ones: the position, the perpendicularity and the parallelism tolerance. Yet we have 14 different types of tolerances in total, which can be anytime... Continue Reading →

THE COOLING LIQUIDS STORY – Part 2 – How cooling liquids that make refrigerators + air-conditioning safe and effective could have the potential to make liquid-breathing possible?
Air-conditioning systems are essentially refrigerators for air. In your car, for instance, the air-conditioning system passes the cabin air over copper tubes containing refrigerant, thus cooling the air. Cool air can't maintain a high concentration of water, which is why water droplets form on air conditioners (this is also why clouds form as air rises... Continue Reading →

MECHANICAL DESIGN ENGINEERING – Geometrical Dimensioning and Tolerancing_What is the POSITION tolerance?
Location tolerances determine the nominal location or ideal location of a feature relative to one or more references. This results in 3 types: Position: the nominal location is determined by theoretical dimensions Coaxiality/Concentricity :The nominal location is the axis or the center of the reference element Symmetry: The nominal location is the median plane or...

MECHANICAL DESIGN ENGINEERING – Geometrical Dimensioning and Tolerancing_What is the ANGULARITY tolerance?
Objects made as an assembly of more than 1 component, in order to be functional besides a clearly specified form each component, must have at least 1 clearly specified orientation (parallel, perpendicular or angular). For the parallelism and perpendicularity the orientation is quite simple to understand , it is either at 0° or at 90°,... Continue Reading →
