Writing for The Observer, Kitty Empire was scathing, describing the medley as "execrable". When the single reached number 1 in the Irish Singles Chart, RTÉ described the news as "shocking", noting the single as "just a bit ho hum". The Belfast Telegraph was equally critical, blasting the cover as a "travesty" that had been "re-worked into a sanitised Comic Relief single", which were "scrappy shadows of the originals".
Our ability to hear is crucial for providing information about the world around us. Sound is produced when an object vibrates the air around it, and this vibration can be represented as a wave that travels through space. For example, if a branch falls off a tree and hits the ground, the air pressure around the branch changes when it hits the earth and, as a result, the vibration of the air produces a sound originating from the collision. One thing that many people do not realize is that sound waves have physical properties and are therefore influenced by the environment in which they occur. In the vacuum of space, for instance, sounds cannot occur because, in a true vacuum, there is nothing to vibrate and cause a sound wave. The two most important physical qualities of sound are frequency and amplitude. Frequency is the speed at which a sound wave vibrates, and it determines the pitch of a noise. Higher frequency sounds have a higher pitch, like a flute or a bird chirping, while lower frequency sounds have a lower pitch, like a tuba or a large dog barking. The amplitude of a sound wave can be thought of as the strength of the vibrations as they travel through the air, and it determines the perceived loudness of the sound. As you can see in Figure 1, when the peak of the sound wave is smaller, the sound will be perceived as quieter. If the peak is larger, then the sound will seem louder. It might even help to think of sound waves like waves in an ocean. If you stand in still water and drop a pebble near your legs, it will cause a small ripple (a tiny wave) that does not affect you much. But if you stand in the ocean during stormy weather, the large incoming waves may be strong enough to knock you down! Just like the size and strength of water waves, the size, and strength of sound waves can have a big effect on what you hear.
One important function of human ears, as well as the ears of other animals, is their ability to funnel sounds from the environment into the ear canal. Though the outer ear funnels sound into the ear, this is most efficient only when sound comes from the side of the head (rather than directly in front or behind it). When hearing a sound from an unknown source, humans typically turn their heads to point their ear toward where the sound might be located. People often do this without even realizing it, like when you are in a car and hear an ambulance, then move your head around to try to locate where the siren is coming from. Some animals, like dogs, are more efficient at locating sound than humans are. Sometimes animals (such as some dogs and many cats) can even physically move their ears in the direction of the sound!
Humans use two important cues to help determine where a sound is coming from. These cues are: (1) which ear the sound hits first (known as interaural time differences), and (2) how loud the sound is when it reaches each ear (known as interaural intensity differences). If a dog were to bark on the right side of your body, you would have no problem turning and looking in that direction. This is because the sound waves produced by the barking hit your right ear before hitting your left ear, resulting in the sound being louder in your right ear. Why is it that the sound is louder in your right ear when the sound comes from the right Because, like objects in your house that block or absorb the sound of someone calling you, your own head is a solid object that blocks sound waves traveling toward you. When sound comes from the right side, your head will block some of the sound waves before they hit your left ear. This results in the sound being perceived as louder from the right, thereby signaling that that is where the sound came from.
Video games and movies become more immersive and life-like when paired with these tricks of 3D audio. When watching a movie, for example, sets of speakers within the movie theater can focus the sound direction to allow for a match between what you are seeing and what you are hearing. For example, imagine that you are watching a movie and an actress is having a phone conversation on the right side of the screen. Her speech begins to play mostly through the right speakers, but as she moves on the screen from right to left, the sound follows her gradually and smoothly. This effect is the result of numerous speakers working in tight synchrony, to make the 3D audio effect possible.
Virtual reality (VR) takes this immersive experience to a higher level by changing the direction of the sound based on where you are looking or are positioned in virtual space. In VR, by definition, you are virtually placed in a scene, and both the visual and auditory experiences should mirror your experience of the real world. In a successful VR simulation, the direction of your head movements and where you are looking determine where you perceive the audio as originating from. Look directly at a space ship and the sound of its engines come from straight ahead of you, but turn to the left and now the sound comes at you from the right. Move behind a big object and now the virtual sound waves hit the object directly and hit you indirectly, dampening the sound and making it more seem muffled and quieter.
The One Direction fanbase believes the boys were roped into signing contracts that gave them pretty much no creative freedom. After a leak revealed The X Factor contract in 2008 which protected Simon from any of the acts saying defamatory things about him, Directioners definitely think the boys had to hold their tongues while working with him and not express any of the anxieties or pressures they were feeling.
LEDs are all around us: In our phones, our cars and even our homes. Any time something electronic lights up, there's a good chance that an LED is behind it. They come in a huge variety of sizes, shapes, and colors, but no matter what they look like they have one thing in common: they're the bacon of electronics. They're widely purported to make any project better and they're often added to unlikely things (to everyone's delight).
Unlike bacon, however, they're no good once you've cooked them. This guide will help you avoid any accidental LED barbecues! First things first, though. What exactly is this LED thing everyone's talking about
In electronics, polarity indicates whether a circuit component is symmetric or not. LEDs, being diodes, will only allow current to flow in one direction. And when there's no current-flow, there's no light. Luckily, this also means that you can't break an LED by plugging it in backwards. Rather, it just won't work.
The positive side of the LED is called the "anode" and is marked by having a longer "lead," or leg. The other, negative side of the LED is called the "cathode." Current flows from the anode to the cathode and never the opposite direction. A reversed LED can keep an entire circuit from operating properly by blocking current flow. So don't freak out if adding an LED breaks your circuit. Try flipping it around.
The brightness of an LED is directly dependent on how much current it draws. That means two things. The first being that super bright LEDs drain batteries more quickly, because the extra brightness comes from the extra power being used. The second is that you can control the brightness of an LED by controlling the amount of current through it. But, setting the mood isn't the only reason to cut back your current.
The interesting thing about resistors is that they'll dissipate extra power as heat, so if you have a resistor that's getting warm, you probably need to go with a smaller resistance. If your resistor is too small, however, you run the risk of burning out the LED! Given that you have a handful of LEDs and resistors to play with, here's a flow chart to help you design your LED circuit by trial and error:
Another way to light up an LED is to just connect it to a coin cell battery! Since the coin cell can't source enough current to damage the LED, you can connect them directly together! Just push a CR2032 coin cell between the leads of the LED. The long leg of the LED should be touching the side of the battery marked with a "+". Now you can wrap some tape around the whole thing, add a magnet, and stick it to stuff! Yay for throwies!
Next, we've got this fan-shaped graph that represents the viewing angle of the LED. Different styles of LEDs will incorporate lenses and reflectors to either concentrate most of the light in one place or spread it as widely as possible. Some LEDs are like floodlights that pump out photons in every direction; Others are so directional that you can't tell they're on unless you're looking straight at them. To read the graph, imagine the LED is standing upright underneath it. The "spokes" on the graph represent the viewing angle. The circular lines represent the intensity by percent of maximum intensity. This LED has a pretty tight viewing angle. You can see that looking straight down at the LED is when it's at its brightest, because at 0 degrees the blue lines intersect with the outermost circle. To get the 50% viewing angle, the angle at which the light is half as intense, follow the 50% circle around the graph until it intersects the blue line, then follow the nearest spoke out to read the angle. For this LED, the 50% viewing angle is about 20 degrees. 59ce067264
