Material Science Quotes

“Since 1963, LEGO bricks have been manufactured from acrylonitrile-butadiene-styrene copolymer - ABS copolymer for short - a plastic with a matte finish. It is very hard and robust - import criteria for a children's toy. Laboratories in Switzerland and Denmark regularly test the quality of the ABS. The plastic is distributed to factories as granules rather than in liquid form. These grains of plastic are heated up to 232ºC and converted into a molten mass. Injection moulding machines weighing up to 150 tonnes squeeze the viscous plastic mass into the desired injection moulds - of which there are 2,400 varieties. After seven seconds, the brick produced in this way has cooled down enough to be removed from the mould. The injection moulding method is so precise that out of every million elements produced, only about 18 units have to be rejected. Unsold bricks are converted back into granulates and recycled.”

“...If we can achieve this, then one day whole rooms, buildings, perhaps even bridges may generate their own energy, funnel it to where it is needed, detect damage, and self-heal. If this seems like science fiction, bear in mind that it is only what living materials do already.”

“Solid, liquid, transient materials, to which controlling their structure is still fiction, but possible.”
