Microchips: Make And Usage
Built on multiple layers, microchip makers use a process called photolithography using chemicals and light. It is generally covered with a thin layer of aluminium.
Apart from computers and laptops, Smartphones are the most common electronic devices carrying a whole lot of chips. Television sets, GPS devices, ID cards and Air Force missiles use this technology.

Smaller than a fingernail, Microchips are integrated circuits providing computer circuitry that is one of the most important inventions of the human race.
A microchip is basically an interconnected circuitry of transistors and resistors etched on semiconducting material like germanium or silicon. The Microprocessor of a computer, and the computer memory, both contain microchip circuits. Most modern gadgets contain this piece of technology.
An organic solar cell is a type of photovoltaic that uses organic electronics—a branch that deals with conductive organic polymers or small organic molecules for light absorption and charge transport to produce electricity from sunlight using photovoltaic effect. Organic solar cells are cheap, resulting in low production costs to form large volumes. Due to the high optical absorption coefficient () of organic molecules, large amounts of sunlight can be absorbed easily and efficiently.
Consciousness is everything you experience - taste, pain, love, feeling. Where these experiences come from is a mystery.
Many modern analytic philosophers of mind either deny the existence of consciousness, or they argue that they can never be meaningfully studied by science.
The Escalator, or ‘moving stairs’ is an infrastructural technological development which is actually a trademark, a brand that became so common that its name became a ‘trademark genericide’, just like Aspirin, or Cellophane.
Escalators came after elevators and of course, stairs, both of which were serving the purpose, but had many constraints like vertical expansion of space and a limit on how much a person can ascend or descend manually.
