If the metal of the paper clip was comprised of more tightly packed crystals, as is the case with steel, for example, the paperclip would not bend.
Rather, it would snap in half, as the crystals would have no room to maneuver. So, put simply, soft materials are soft because their substructures are packed more loosely.
Stuff Matters Key Idea 3: Living and non-living matter differ mostly in how they react to stimuli. Atomically, our bodies are composed of some of the most common elements on earth: carbon, hydrogen, oxygen and nitrogen.

Consider what happens when a material encounters an external stimulus like fire, for example. Sure, non-living materials can react to it by bending, snapping or resonating, but this is a mere passive reaction: the fire acts on them rather than the other way around.
Stuff Matters Key Idea 4: Our choice of materials often has an emotional as well as a practical component. Have you ever wondered why we have such high regard for material possessions in modern society?
In fact, archeological evidence shows us that as soon as humanity developed tools, we also began to produce items of pure social value, like decorative jewelry, art and clothing. And sometimes the social or emotional value of an object can even be more important than its utility, as the materials we use for certain items tells us. Consider the fact that stainless steel is cheap, highly durable and easy to clean.
Why do we instead rely on delicate, breakable ceramics in the dining room and bathroom? Nor do we like steel to be part of the passing our most intimate wastes. So where do these emotional bonds with materials come from? The connotations we give materials are influenced by where we encounter them in our everyday environment.
By looking at these tiny particles on a smaller scale, we can better understand their properties, and begin to create even more incredible materials in the future. Suggested further reading: A Short History of Nearly Everything by Bill Bryson A Short History of Nearly Everything offers an enlightening summary of contemporary scientific thinking relating to all aspects of life, from the creation of the universe to our relationship with the tiniest of bacteria.

See chemistry above. It can be transformed from rustic to official, from retro to glamorous, simply by changing the surface layer.
Controlling these aesthetic considerations is vital to the economic fortunes of commercial publications.
Perhaps this is because there is an undeniable reality to the newspaper itself: it is a real material object. That authenticity rubs off on the news.
It can be pointed to, underlined, cut out, pinned on notice boards, stuck in a scrap-book, or archived in libraries. The news becomes an artifact, frozen in time; the event may be long gone, but it lives on as an indisputable fact because of its material presence—even if it is untrue. The circumference of the earth at the equator is about 40, km.
A calculation the author did literally on an envelope featured in this chapter. Upon heating to a temperature of Celsius, the mixture starts to fall apart and form calcium silicates.
Correct proportions of aluminum and iron rich rock impurities are needed to turn it into concrete. Once cooled down, the resulting ashy mixture is called cement. When water is added to cement, it starts to form a gel that hardens into a matrix composed of crystal-like calcium silicate hydrate fibrils.
As the fibrils grow in the presence of water, they expand and mesh together trapping more and more of the water until it changes from a gel-like consistency back to hard rock. Adding too much water will result in residual water unreacted with calcium silicates weakening the concrete.
Too little water leaves unreacted cement which also weakens the structure of the concrete. He was trying to construct plant pots that were not made of terra cotta or fired clay due to its weakness. He tried concrete but it was still weak. To strengthen it, he embedded loops of steel inside the concrete. As his luck would have it, the concrete calcium silicate fibrils bonded both the rocks and the metals.
The strength and endurance of reinforced concrete also have to thank very similar coefficient of expansions between concrete and metal. They are embedded along with starch in the concrete within the calcium silicate fibrils.
With embedded bacteria, the bacteria themselves are also released, feed on the starch, grow and replicate, and produce calcite a form of calcium carbonate that can then bond and seal the crack.
Microscopic crystals of titanium oxide layered on the surface.Published on Jul 22, Janus ink is composed of dye particles that have a white side and black side of opposite electrical charges. And sometimes the social or emotional value of an object can even be more important than its utility, as the materials we use for certain items tells us.
Yellowing can also be caused by residual lignin which reacts with oxygen producing chromophores which turn paper yellow e. In other cases — say, setting an aperture that balances diffraction with depth of field — you may have plenty of time to do trial-and-error in the field assuming typical conditions without really understanding the topic.
