Appreciation of Crash Course

It is quite boring and tedious, to study a subject that is far from your interest. However, some media tools make this process a lot easier. And I think it’s well worth to appreciate them. What I feel thankful this week is Crash Course, educational youtube channel. It has numerous subjects and many series about the each specific subject. World history, biology, chemistry, psychology, economy, astronomy, literature and many more.

As I was watching about the subjects I’m not an erudite, they catalyse me to cover my missing knowledge although they are probably design for teenagers.

Elaborately prepared and presented episodes keep my attention and teach it effectively, plus, they stimulate further questions around the topics. They are so much more than mediocre educational videos.

Meanwhile, You don’t have to pay fro watching videos.  Hence, you can watch freely.

Maxwell’s Equation

Scottish physicist James Clerk Maxwell(1831–79),  wrote equation that are simply enlightening. He worked on the ideas of Faraday and Kelvin, and succeeded in unifying electricity and magnetism, identifying the electromagnetic nature of light, and postulating the existence of other electromagnetic radiation.

Visible light, x-rays, sunlight , radio waves, television waves, wifi signals, bluetooth signals, cell phone transmission, and GPS all consist solely of Electric and Magnetic Fields. And how they propagate and interact with materials is completely determined by the above 2 equations of Maxwell.

First equation: The electric flux through a closed surface is proportional to the total charge enclosed by that surface.

Second equation: Maxwell second equation is also a form of Gauss’s law, only with magnetic flux instead of electric flux.

Third equation is modified version of Faraday’s equation.

Media History

Geological and Biological side of the media

As Jussi Parrika writes in his book called A Geology of Media “Media history conflates with earth history ; the geological materials of metals and chemicals gets deterritorialized from their strata and reterritorialized in machines that defines our technical media culture.” (pg 35)


For instance, obviously, cooper is essential for the modern life or Silicon and germanium (fiber optic cable, IR optical technologies) are fundamental for computer culture.

“Our media devices and political economy of digital culture are dependent on energy (cloud computing is still too a large extent powered by carbon emission – heavy energy production) and materials ( metals, minerals, and a long list of refined and synthetic components)” (pg 43, Parikka)

Standarts Organizations

Important organisations to put some order to computer networks and data communications:

  • IEC – International Electrotechnical Commission
  • ITU – International Telecommunication Union
  • EIA – Electronic Industries Association
  • TIA – Telecommunications Industry Association
  • IETF – Internet Engineering Task Force
  • IEEE – Institute of Electrical and Electronic Engineers
  • ISO – International Organisations for Standardisation
  • NIST – National institutes of Standards and Technology
  • IBM – International Business Machines


Communication change significantly by the invention of Samuel Morse in 1937. Telegraph enable to send information using electrical pulses over a copper wire. (morse code)

Alexander Graham Bell took the telegraph one step further in 1876. he proved that voice can be converted directly to electrical energy and transmitted over q wire using continuous diversified voltages.

Theory of Meme

According to the theory of Richard Dawkins memes just like genes have no  purpose beyond their own reproduction. Important contribution to Theory of Meme is done by computer programmer Richard Brodie “who defines the meme as the virus of the mind, and who identifies three method of infection: repetition, cognitive dissonance, and Trojan Horses.  The most effective way to insert meme into mind is the repetition. A brief glance at the modern communication, from advertising to the media’s obsessive repetition of keywords such as “terrorist” and “crisis” easily enables us to understand this process.” (Campenelli, Vito.
