  JC Church 9/15/26 Digital Media: Theory and Practice Questions for Media and Digital Technology 1. What is mediation? How do digital technologies illustrate mediation in modern social, political, and economical life?      Mediation is the process through which a medium such as technology shapes how people communicate, understand information, and experience the world. Instead of experiencing many events or relationships first hand, people often encounter them through some form of mediation. In social life, technologies such as social media, messaging apps, and video-calling platforms mediate how people communicate and maintain relationships. They allow people to interact across long distances and create online communities. In political life, digital technologies mediate how citizens receive political information and participate in public debate. Social media and online news platforms allow people to follow politicians, discuss political issues, organize movements, a...

Molecular Gastronomy   By: Shahminah Mahar-ullah Date:3/22/19 Molecular Gastronomy is both a fusion of science and cooking. The scientific discipline gives the chef complete control of what the texture, taste, and physical appearance of the dish. Molecular Gastronomy is a modern unique style of cooking that some would say it could be considered art. There are three aspects of Molecular Gastronomy, as i said before it is texture,taste,and physical appearance. Molecular Gastronomy can have a very simple and familiar taste or a new and unique taste. Taste is often a aspect that is forgotten about in Molecular Gastronomy. Mostly because people who don't know much about the style of cooking kinda forget that its actually cooking ,not just some form a science. Taste is the main focus with cooking in general and with molecular cooking taste can be brought to a whole new level since you have complete control over each part of the dish. Same goes for physical appearance and ...

Magnetism in credit cards Shahminah Mahar-ullah 3/29/19 The ­stripe on the back of a credit card is a magnetic stripe, often called a mag-stripe. The mag-stripe is made up of tiny iron-based magnetic particles in a plastic-like film. Each particle is really a very tiny bar magnet about 20 millionths of an inch long. After you or the cashier swipes your credit card through a reader, the EDC software at the point of sale, terminal dials a stored telephone number via a modem to call an acquirer. An acquirer is an organization that collects credit authentication requests from merchants and provides a payment guarantee to the merchant. When the acquirer company gets the credit card authentication request, it checks the transaction for validity and the record on the mag-stripe for merchant ID, valid card number, expiration date, credit card limit, and card usage. In my opinion I think this can get us pretty far in the future. We already use magnetism in so many things ...

Helium atoms Shahminah Mahar-ullah 3/28/19 A helium atom is an atom of the chemical element helium, a basic element found on the periodic table of elements. Helium as a chemical element is composed of  two protons, two electrons and two neutrons. Because it has two protons and two neutrons, helium's atomic weight is 4. It is an inert gas and therefore one of the noble gasses. A substance being inert indicates that it does not chemically react. When a balloon is filled with helium, it rises because of the difference in densities between the inside of the balloon and the air outside of the balloon. Because helium itself is a very light atom, the helium gas in the balloon is lighter than the air around it, making its density relatively low and so it rises. If a balloon is filled with helium slowly deflates over time. That's not including temperature and without puncturing the balloon, because the helium atoms are small enough to escape between the molecules of the b...

Earth's Magnetic Poles Shifting Earth's north pole has seemed to start moving faster than usual. For earth's magnetic poles to move is not unusual and actually happened often in the past. The north pole which located in the Canadian Arctic, has slowly started to move to the Russian, around a staggering 37 miles a year. In the 1800 it was known for the poles to drift but in the later 1900 the poles have seemed to move at a faster rate. It even went so far to cross over a national date line in 2018, this shows how fast the magnetic poles can switch. The question on why this is happening might show up. Well the magnetic poles have switched before around 720,000 years ago. From what scientist can estimate we are in the stone age of the magnetic poles flipping. This is a result of earth's liquid iron core, and the large magnetic field running through it has a center that center is decreasing every year and increasing more somewhere else. Through the years it will  ...

Claudia Morales                                                                                                           3/27/19 Are Electricity and Atoms the Same? Electricity is the movement of electrons between atoms.  The electrons stay a constant distance from the atom`s nucleus in specific shells.  The inner shell can hold 2 electrons while the outer shell can hold up to 8 electrons or more.  The inner shell attracts more protons than the outer shell.  Since the outer most shell doesn't have as much of a strong force with the protons those electrons start to shift.  This shift is what causes electricity. While atoms are made up from smaller particles calle...

Magnetic Tattoos   Tattoos have been a prevalent part of culture since ancient times. They represent a rite of passage and could symbolize religious meaning. Throughout history tattoos have improved and changed ever since the invention of the tattoo gun in the 1800’s. Currently, some tattoo inks contain certain amounts of ferrous metals such as iron oxides. Red tattoo ink is most commonly the carrier of these types off metals and can rarely have negative effects. One example is that these metals can sometimes react to very powerful electromagnetic fields.    Red tattoo ink only contains trace amounts of iron and that can react very violently to powerful electromagnetic fields in certain circumstances. But imagine if magnetic materials were purposefully added to tattoo ink. Nokia had patented for an idea for tattoos that could potentially buzz when your phone rings.   Only very few metals are magnetic regardless of popular belief. Iron, nickel...
