The Underlying Science And Physics Behind Touchscreens On Iphones

In the article "Energy Story". I learned that electricity figures are everywhere and where electricity comes from. Did you know that electricity comes from atoms? atoms are the proton, the neutron, and the electron. Nevertheless, electrons contain negative charge, protons are positive and neutrons are neutral, I also learned that a charged atom is called an ion.

* Protons and electrons have equal and opposite electrical charges. Protons are positively charged, and electrons are negatively charged.

Electrons are the negatively charged particles that can be found in the atom. Electrons will be located around clouds that surround the nucleus of an atom. All Together the atom creates a negative charge that will make sure that it balances the positive charge of the protons in the atomic nucleus. These clouds are at a certain distance from the nucleus which is properly put into the shells. Due to the fact that electrons move so quickly it is impossible to see where they are at certain point in time. The overall shape of the shells change depending on how many electrons an element contains. The higher the atomic number the more higher the shells plus an electron of an atom will have. The main in electrons is the way that all the elements rely on each other without the negative charge is the positive will not be good in any use. The electrons are an everyday use to use because of the fact of electricity. The small particles flows through wires and circuits that create currents of electricity. Electrons flow from negative charged parts to the positive charged. The negative charge part of a circuit will have extra electrons, meanwhile the positive charge will want more electrons. When electrons move throughout

One of these properties is called an electrical charge. Protons have a "positive" (+) charge, electrons have a "negative" (-) charge, and neutrons have no charge, they are neutral.

An electric current exists when there is a net flow of charge through a given area. Electrons flow from the negatively charged region to the positively charged region. This is usually accomplished by using an electrical conductor which allows the electrons to pass freely through the material (Serway, et al. 709). This flow of electrons can generate heat when collisions between the molecules and electrons occur. These collisions then cause the molecules to break apart thus releasing heat. Some common examples of electrical energy are lightning, static electricity, and wiring outlets (Coleman, et al. 82). For the wildland firefighter, lightning is probably the

In the nucleus of an atom there are protons and neutrons the number of protons and neutrons depends on the element and ,if it is an isotope of that element. E.g. carbon 12, carbon 12 has six neutrons six protons and 6 electrons . Electrons are located around the nucleus of the atom. Electrons are in shells, the shell closest to the nucleus is 1 , the one after 2 and so on. Each shell can only hold up to a certain number of electrons . the first can hold up to 2 , the second 8 (2+6) the third up to 18 (2+6+10). The general formula for finding out how many electrons a shell can hold is 2n^2. Electrons have a negative charge , while protons have a positive and neutrons have no charge. A atom has the same number of protons and electrons. An ion is formed when an atom loses or gains a electrons .

It starts with subatomic particles, such as protons and electrons, produce electrical fields. These relating electrical fields are composed primarily of electrons,

I know this because in the article it directly say’s “But what is electricity? Where does it come from? How does it work?”. The article begins talking about how energy works, what it is, and where it comes from by explaining what atoms are. It talks about how they are made up of three main particles, protons, neutrons, and electrons. Lastly, it talks about how atoms have a positive and negative charge and also what atoms can pass through.

We are all born with the ultimate pointing device—our fingers—and iPhone uses them to create the most revolutionary user interface since the mouse.” (Apple)

All materials with which we work are made up of atoms. Though atoms are neutral, the atoms themselves are made up of charged particles: Protons which are positively charged, neutrons which have no charge, and electrons which are negatively charged. Even though atoms are neutral, charge can still be transferred through the fact that not all atoms or molecules hold on to their electrons with the same strength, and when two substances are in contact the transfer of charge can occur. In this experiment we will examine the way different objects interact and how under dry conditions some objects become positively charged(Loses electron) and the other become negatively charged(gains electrons).

An Atom is the the basic building block of all matter. Atoms are made up of Particles, called: Protons, neutrons and Electrons. Protons carry a positive charge, the neutron carry 's a neutral charge and the electron carry’s a negative charge. The Atom has two main parts the Nucleus and the Electron Shell. The Nucleus contains the Protons and Neutrons. The electron Shell Contains the The electrons.

The merger of a Palm handheld computer and a mobile telephone is the first device that combines cell phone mobility with powerful computing. Thus, merger of mobility and muscle produces pocket-size prodigy. Hirsch mentioned the Smartphone, by San Diego-based Kyocera, combines a cell phone and a fully functional Palm in a single pocket device. Compared with a regular Palm, it is a little thicker, a little taller and seems a fraction of a second slower to respond to the stylus. The screen is slightly smaller and the device slightly heavier, though the difference is not very noticeable. But the negatives

Apple was the first to integrate a MP3 player into a cell phone. After Apple invented the iPhone, downloading music on ones phone became common. With the unbelievably sharp screen, iPhones took over the gaming market. The phones highly technological A7 chip delivers the type of detailed graphics and multifaceted visual effects that in the past only Mac computers, PCs, and gaming consoles could display (“iPhone” 5). IPhones also introduced the on screen keyboard which were previously unheard of. In addition, Apple launched the touchscreen revolution (Elgan 6).

The iPhone’s success has resulted in the widespread application of touchscreens in many devices. Touchscreens now become a fundamental tool which facilitates daily tasks, such as e-mail, navigation and web browsing. Compared to traditional input devices such as keyboards and mice, touchscreens provide a more natural and direct way to interact with the digital world. However, one drawback of touch interactions in most current devices is that they are still ’two-dimensional’ – the interface feels like flat glass because it produces no tactile feedback, and our interaction is still highly dependent on a pattern of visual feedback. To illustrate, we first look at the content displayed on the screen.

The outer shell of electrons that orbit the nucleus of an atom is called the valance shell. This is what makes a copper atom conduct. For a copper atom the number of electrons is one. When a charge of electricity is placed in the end of a wire the electrons move into the wire. Since there is only one electron in the valance shell of a copper atom it can be easily dislodged with a small amount of energy causing it to jump to the next atom. This will then cause the valance electron of that atom to jump to the next atom and so forth. This movement happens very fast making it possible for a large number of electrons to move through the wire. An example of a conductive atom is shown figure 1.
