They want the right to be ignored by the people who they see as being “in their business.” Teens are not particularly concerned about organizational actors; rather, they wish to avoid paternalistic adults who use safety and protection as an excuse to monitor their everyday sociality. (Boyd, 56) This chapter, and in particular this section, […] Continue reading
I believe that given the time he has written this in, Simon Singh has done an excellent job of predicting how the upturn of technology would shift our society and our world towards one of automatic work and technical organization. It turns out that Singh largely underestimated the rate at which all of this would […] Continue reading
It’s almost comical to read Singh’s prediction, considering the digital world we live in today. He predicts that “electronic mail will soon become more popular than conventional mail,” and that governments will use the internet to help run their countries. These statements have long been true. In fact, I can’t remember the last time I […] Continue reading
It’s impossible to be a citizen of the 21st century without being somewhat familiar with the ubiquitous, ever-changing phenomenon of “Internet culture”. My generation never even knew a time without the Internet. Every day of our lives, we consume thousands of bite-sized chunks of micro-content from our smartphone screens designed to grab our attention and […] Continue reading
It is said that history is written by the winners, but many forget the second part of of that statement, that history is also written about only the powerful and important. The examples of cryptography that survived throughout the ages were those that caused great uproar, such as the beheading of Mary Queen of Scots. […] Continue reading
Space propulsion is different from regular propulsion methods that deal with situations on the ground or in the air. It’s also different from launch propulsion which space propulsion methods exclusively deal with propulsion systems used in vacuum of space. Before introducing different propulsion methods, there are couple of concepts that are really important related to … Continue reading Introduction to various spacecraft propulsion methods → Continue reading → Continue reading
As a species, we need multiple paths to survival. One of which is living in space. With this in mind, companies like SpaceX have plans to colonize Mars. But why Mars? It is the next most habitable planet after Earth. It contains water, temperatures that are not too hot nor too cold, enough sunlight, ability … Continue reading The Quest to Inhabit Mars → Continue reading → Continue reading
A propulsion method I was unaware of is electric propulsion (EP). An EP system consists of thruster components, propellant components, power components, and an optional pointing mechanism. Essentially, electric and magnetic fields react to charged particles in the rocket’s exhaust which accelerates charged particles that make up propellant. This requires less energy than chemical rockets … Continue reading Electric Propulsion → Continue reading → Continue reading
In the center of the galaxy M87, stars seem to orbit an invisible object. By observing the path of the stars, scientists concluded that there is a supermassive black hole that is dense enough to cause these motions. Although the black hole itself is invisible, we can still observe the ring of light bended by … Continue reading Hello Powehi → Continue reading → Continue reading
